Adults who voluntarily take part in mindfulness courses are less likely to experience symptoms of anxiety and depression for at least six months after completing the programmes, compared to adults who do not take part, a new analysis pooling data from 13 studies has confirmed.

This study is the highest quality confirmation so far that the in-person mindfulness courses typically offered in the community do actually work for the average person.Dr Julieta Galante

University of Cambridge researchers looked at participants of group-based and teacher-led mindfulness courses, conducted in person and offered in community settings.

They say the results, published in the journal Nature Mental Health, should encourage uptake of similar teacher-led programmes in workplaces and educational institutions keen to help prevent mental health problems developing in members of their community.

“In our previous work it was still not clear whether these mindfulness courses could promote mental health across different community settings,” said lead researcher, Dr Julieta Galante, who conducted the research while at the University of Cambridge. “This study is the highest quality confirmation so far that the in-person mindfulness courses typically offered in the community do actually work for the average person.”

Mindfulness in these courses is typically defined as “the awareness that emerges through paying attention on purpose, in the present moment, and nonjudgmentally to the unfolding of experience moment by moment”.

These courses, formally known as mindfulness-based programmes (MBPs), often combine elements of meditation, body awareness and modern psychology, and are designed to help reduce stress, improve wellbeing, and enhance mental and emotional “resilience”. They consist of groups of participants led by mindfulness teachers, who promote reflection and sharing over several one-to-two hour sessions.

The body of research into the effectiveness of MBPs to date has been mixed. Cambridge researchers sought to confirm the effect of MBPs on psychological distress ‒ which encompasses disturbing or unpleasant mental or emotional experiences including symptoms of anxiety and depression.

They pooled and analysed data from 2,371 adults who had taken part in trials to assess the effectiveness of MBPs. Roughly half the participants had been randomly allocated places on mindfulness programmes that lasted for eight weeks, with a one- to two-and-a-half hour session per week and compared them to those that were not through self-reported questionnaires.

The study found that MBPs generated a small to moderate reduction in adults’ psychological distress, with 13% more participants seeing a benefit than those who did not attend an MBP.

The researchers found that existing psychological distress, age, gender, educational level and a disposition towards mindfulness did not change the effectiveness of MBPs.

Galante said: “We’ve confirmed that if adults choose to do a mindfulness course in person, with a teacher and offered in a group setting, this will, on average, be beneficial in terms of helping to reduce their psychological distress which will improve their mental health. However, we are not saying that it should be done by every single person; research shows that it just doesn’t work for some people.

“We’re also not saying you should absolutely choose a mindfulness class instead of something else you might benefit from, for example a football club – we have no evidence that mindfulness is better than other feel-good practices but if you’re not doing anything, these types of mindfulness courses are certainly among the options that can be helpful.”

The researchers conducted a systematic review to select previous studies for inclusion in their large-scale analysis. They obtained complete but anonymised data from 13 trials representing eight countries. The median age was 34 years-old, while 71% of participants were women.

While mindfulness apps are on the rise, researchers remain unsure whether it is the practice of mindfulness that reduces psychological distress, or the fact that courses involve in-person group-work with a teacher present.  

“Apps may be cheaper, but there is nowhere near the same evidence base for their effectiveness,” said Galante. “Some apps may say they are evidenced based, but they are often referring to trials that are in-person with a teacher and a group.”

The effectiveness of smartphone apps, as well as what happens when people continue to practice mindfulness meditation by themselves, will be investigated by Galante, who has recently taken up a new position as Deputy Director of the Contemplative Studies Centre, at the University of Melbourne.

“If you are offered an in-person four- or eight-week mindfulness course in a group setting with a teacher, and you are curious about it, I’d say based on this study, just go ahead and try it,” said Galante. “And for organisations wondering about offering these types of mindfulness courses to members of their community – this research suggests it may be a good investment if their communities express an interest.”

This research was funded by the National Institute for Health Research.

Helping adolescents to feel competent and purposeful – not just happy – may improve grades

Students in the classroom

source: www.cam.ac.uk

Study of 600 teenagers suggests that having stronger self-awareness and sense of purpose may raise GCSE Maths scores “by a couple of grades”.

Wellbeing education needs to move beyond notions of ‘boosting’ happiness towards deeper engagement, helping adolescents to realise their unique talents and aspirationsRos McLellan

Encouraging adolescents to feel capable and purposeful – rather than just happy – could improve their academic results as well as their mental health, according to new research which recommends changing how wellbeing is supported in schools.

The University of Cambridge study, involving over 600 teenagers from seven English schools, examined two separate aspects of their wellbeing: life satisfaction and ‘eudaimonia’. While life satisfaction roughly equates to how happy a person is, eudaimonia refers to how well that person feels they are functioning. It incorporates feelings of competence, motivation and self-esteem.

Researchers found that students with high levels of eudaimonia consistently outperformed their peers in GCSE-level assessments, especially Maths. On average, those achieving top Maths grades had eudaimonic wellbeing levels 1.5 times higher than those with the lowest grades.

No such link was found between academic performance and life satisfaction. Despite this, child wellbeing policy in England tends to focus on life satisfaction. The Government has, for example, recently added ‘happiness’ to national curricula as part of its Relationships, Sex and Health Education (RSHE) guidance, emphasising teaching adolescents how to feel happy and resilient while managing negative emotions.

Previous research has pointed to the importance of fostering adolescents’ eudaimonic wellbeing by nurturing their personal values, goals and sense of self-worth. The new study appears to strengthen that case by demonstrating a positive link between eudaimonia and academic performance.

Its lead author, Dr Tania Clarke, is a psychologist of education who now works for the Youth Endowment Fund, but undertook the study for her doctoral research at the Faculty of Education, University of Cambridge. The findings are published in School Psychology Review.

“Wellbeing education often focuses on teaching students about being happy and not being sad.” Clarke said. “That is over-simplistic and overlooks other vital qualities of wellbeing that are particularly salient during the formative period of adolescence.”

“Adolescents also need to develop self-awareness, confidence, and ideally a sense of meaning and purpose. Judging by our findings, an adolescent who is currently getting a 3 or 4 on their Maths GCSE could be helped to rise a couple of grades if schools emphasised these qualities for all students, rather than just promoting positivity and minimising negative emotions.”

The study involved 607 adolescents, aged 14-15. Participants completed an established psychological assessment called ‘How I feel about myself and school’, which measures both life satisfaction and eudaimonia, as well as feelings of interpersonal relatedness and negativity.

These measures were compared with their scores in mock English and Maths GCSEs. The research also assessed whether the students exhibited a ‘growth mindset’: a belief in their personal capacity for improvement. Many educators consider this essential for enhancing academic performance.

The students’ overall wellbeing – their eudaimonia and life satisfaction combined – clearly correlated positively with their exam results. Those attaining top Maths grades (Grades 8 or 9) had, on average, a wellbeing score of 32 out of a possible 50. This was nine points higher than those with a Grade 1, and three to four points higher than the average for all 607 students.

When they analysed the separate dimensions of wellbeing, however, the researchers found a positive relationship between eudaimonia and higher attainment, but no correlation with life satisfaction. In Maths, the average eudaimonic wellbeing score of Grade 9 students was 17.3 from a possible 25, while that of Grade 1 students was just 10.9. These results held true even when accounting for potentially confounding factors, such as school attended, gender, socio-economic status, or special educational needs.

The study also found that a growth mindset did not predict good academic results, although students with high eudaimonic wellbeing did tend to exhibit such a mindset. Other research has similarly struggled to draw a clear link between growth mindset and academic progress, but does link it more generally to positive mental health. This implies that eudaimonia, as well as supporting better attainment, may also underpin important aspects of self-belief, leading to broader mental health benefits.

Clarke’s wider research suggests that various constraints currently limit schools’ capacity to promote eudaimonic wellbeing. In an earlier Review of Education article she published the results of in-depth interviews with some of the same students, which highlighted concerns about a ‘performativity culture’ stemming from a heavy emphasis on high-stakes testing. These interviews indicated that many students associate ‘doing well’ with getting good grades, rather than with their own strengths, values and goals.

Students said they often felt worthless, inadequate or “dumb” if they failed to get high marks in tests. “You let your scores define you,” one student told Clarke. “Then you feel really low about… your worth and everything. You think it’s literally the end of the world.” Ironically, the new findings suggest that by limiting teachers’ capacity to support students’ personal growth, the heavy emphasis on exam results and testing may be undermining academic progress, at least in some cases.

Clarke suggested that eudaimonic therapy, which increasingly features in professional mental health psychology for adolescents, could be incorporated more into wellbeing education. In particular, her study underscores the need to help students understand their academic work and progress in the context of their personal motivations and goals.

“There is a link between better wellbeing and a more nuanced understanding of academic success,” Clarke said. “Because schools are under heavy pressure to deliver academic results, at the moment students seem to be measuring themselves against the exam system, rather than in terms of who they want to be or what they want to achieve.”

Dr Ros McLellan, from the Faculty of Education, University of Cambridge, who co-authored the study, said: “Wellbeing education needs to move beyond notions of ‘boosting’ happiness towards deeper engagement, helping adolescents to realise their unique talents and aspirations, and a sense of what happiness means for them, personally. This would not just improve wellbeing: it is also likely to mean better exam results, and perhaps fewer issues for students later on.”

Cambridge Enterprise, the research commercialisation arm of the University of Cambridge, marked its 15th anniversary with a remarkable series of achievements.

With 304 patent applications filed, 144 licences executed, a record 441 consultancy contracts signed, and a seed fund portfolio valuation at an all-time high of £124 million, Cambridge Enterprise is helping the University deliver real impact.

Cambridge Enterprise’s contribution to the UK economy through innovation is part of the wider financial impact of the University of Cambridge – which, according to a recent London Economics report, contributes almost £30 billion to the UK economy. Over 77% of this total contribution is the result of commercialisation of knowledge transfer activities.

Last year Cambridge Enterprise returned over £20 million to the University and its departments – supporting the development of an entrepreneurial culture and re-investing in research and education. The scale of these returns affirms the crucial role of Cambridge Enterprise in fuelling innovation on behalf of the University, and demonstrates the overall success of Cambridge Enterprise’s activity.

It has been a year for demonstrating the value and potential of University research commercialisation activities. Cambridge Enterprise also played a leading role in the publication of the TenU University Spin Out Investment Terms (USIT) guide. The guide was developed in partnership with six leading university technology transfer offices and a number of leading venture capital firms and represented the first joint commitment of both the university sector and venture capitalist community.  The guide sets out a landing zone for University led spin out deals and will be a critical tool in transforming research commercialisation in the UK, speeding up negotiations and attracting greater levels of investment.

In partnership with Cambridge Innovation Capital and the University of Cambridge, Cambridge Enterprise has also this year led to the creation of Innovate Cambridge  – a new initiative to develop an inclusive, forward-looking and ambitious vision for the future of Cambridge and its innovation ecosystem. More than one hundred organisations have pledged their support by signing the Innovate Cambridge Charter, which promotes collaboration, enhancement, and the development of ecosystem-wide initiatives to realise the shared vision. Through the University Enterprise Network, Cambridge Enterprise has additionally established a new IE Cambridge initiative, which aims to make it easier for those who are interested in the Cambridge innovation space to navigate and engage meaningfully with existing activity.

Other standout moments for Cambridge Enterprise this year include:

  • The acquisition of portfolio company Gyroscope Therapeutics – a company Cambridge Enterprise has supported since its initial IP disclosure – by Novartis Pharmaceuticals for an impressive sum of up to $1.5 billion.  
  • £50 million Series B funding round secured by portfolio company Nyobolt, propelling the company’s mission in sustainable energy storage, and scaling up manufacturing operations.
  • A new Commercialisation of Research out of Social Science (CRoSS) initiative in partnership with the University’s Social Sciences Impact team, funded by the UKRI Economic and Social Research Council, inspiring novel approaches to social sciences commercialisation.
  • The ongoing success of DigiVis, an innovative software to self-administer eye tests and improve medical support for eye care, the copyright of which was licensed by Cambridge Enterprise to Cambridge Medical Innovation Limited.
  • Ongoing work to tackling the innovation gap needed to achieve Net Zero with a newly launched Sustainability Initiative, as part of the University’s leadership on and commitment to Net Zero.
  • A total of £10.6 million invested in 34 spin outs in the last financial year.

There has been much to celebrate this year. Universities have long been bastions of optimism and innovation, continuously seeking solutions to global challenges. Cambridge Enterprise is unwavering in its commitment to translating these solutions into real-world impact, benefitting both the economy and the broader society. With the rapid advancements in artificial intelligence and the convergence of physical and digital worlds, the coming decade is poised to be more disruptive than ever. Cambridge Enterprise will therefore seek to increase the impact and influence of University research, acknowledging the urgency for these transformative technologies and supporting the thriving UK innovation ecosystem.

University clinical academic nurse named in NHS Top 75

A clinical academic community nurse at the University of Cambridge has been named as one of the top 75 nurses and midwives who have contributed in a significant way to the National Health Service since its creation.

Dr Ben Bowers, a Wellcome Postdoctoral Research Fellow, has been honoured by Nursing Times as part of celebrations of the 75th anniversary of the founding of the NHS.

Based at the University’s Department of Public Health and Primary Care, Ben specialises in palliative and end-of-life care and is a Postdoctoral Associate at Jesus College, Cambridge. An alum of Homerton College and Trinity Hall, he left school at 16 with no qualifications to his name and it was a chance visit to an Accident & Emergency department that inspired him to go into nursing.

“I am delighted about this award, I’m actually still a bit in shock!” says Ben.

“To be named as one of the leading lights in my field, I can’t even process it properly.”

As a clinical academic, Ben has a dual role, working in healthcare at Cambridgeshire and Peterborough NHS Foundation Trust while researching ways to improve patient outcomes. He is also an interdisciplinary nurse researcher, working with colleagues across engineering, patient safety, social sciences, primary care and palliative care. Ben also co-founded and leads the UK-wide Queen’s Nursing Institute Research Forum, helping to develop community nursing research capacity.

Ben’s research is focused on anticipatory prescribing, under which ‘just in case’ medicine boxes are given to patients who are reaching the end of their life at home. Containing strong prescription painkillers and other drugs, the boxes are intended to ensure that patients have quick and easy access to medicine to ease symptoms of pain and discomfort.

However, Ben’s research has found that prescribing medicine boxes can alarm families, or that they may receive inadequate information about the drugs and symptoms that can be experienced in the last days of life. His research has also found that anticipatory medicine is sometimes used as a ‘sticking plaster’ solution to a more complex problem. 

While Ben fully supports anticipatory prescribing, his research has highlighted a need for better communication with patients and their loved ones. “It’s a critical intervention, we just sometimes need to communicate it better, and put it in place at the right time,” he says.

And his research has had an immediate impact on clinical practice. Ben says: “I’ve had community services come to me and say: ‘It’s so important what you are doing. You’re making us question motherhood and apple pie, challenging clinical assumptions and helping us to improve end-of-life care.’ It’s great to hear that my work is having that impact.”

Ben thinks part of the reason he’s been given the award is because he is still a relatively rare beast in the world of medicine.

“There’s an ambition for at least one in 100 nurses to be clinical academics, when in reality it’s probably less than one in 1,000, so if this award does anything I hope it encourages nurses to consider clinical academia – it’s a brilliant career and can give you the chance to improve patient care on a really wide scale,” says Ben.

Radiotherapy boost cuts breast cancer treatment time by at least one week

Professor Charlotte Coles

source: www.cam.ac.uk

Treatment times for radiotherapy could be reduced for some early breast cancer patients, according to a trial led by University of Cambridge and The Institute of Cancer Research, London.

This is a careful step towards even shorter courses of radiotherapy that include more complex techniques. By delivering more targeted boost radiotherapy over shorter time periods, women can get on with their lives more quicklyCharlotte Coles

Results from the IMPORT HIGH trial, published in The Lancet, show that giving some breast cancer patients a targeted additional dose of radiotherapy at the same time as treament to the whole breast (known as simultaneous integrated boost or SIB) cuts the time taken to complete treatment by at least one week.

The trial, funded by Cancer Research UK and the National Institute of Health Research and Care Research (NIHR), found that SIB radiotherapy given at the right dose works just as well as existing radiotherapy techniques in reducing the risk of the cancer returning in the treated breast.

The chance of the cancer returning to the treated breast remained very low after 5 years across all treatment groups. Patients given the lower dose of SIB radiotherapy reported similar rates of side-effects, like breast hardening or firmness, as those who received the standard sequential radiotherapy schedule.

Currently, women with a higher than average risk of cancer coming back in their treated breast are given an additional radiotherapy dose to the original site of the tumour after radiotherapy is given to the entire breast. This approach, known as sequential boost, maximises the chances that any remaining cancer cells are removed from the breast.

But it takes longer for women to complete sequential boost radiotherapy, requiring them to attend more hospital appointments. In the UK, many women requiring breast boost radiotherapy are given 4 weeks of radiotherapy – 3 weeks to the whole breast with 1 week boost afterwards. In some countries, women are given 6.5 weeks of radiotherapy – 5 weeks of whole breast radiotherapy with 1-1.5 weeks boost afterwards. SIB radiotherapy cuts this down to just 3 weeks in total.

A boost treatment also increases the chance of having potentially long term side-effects after treatment, including changes in shape, size and texture of the breast that can affect women’s self-esteem and wellbeing.

In total, 2,617 patients at 76 centres took part in the trial. Patients were divided into three groups. The first group received whole breast radiotherapy with a sequential boost over 4.5 weeks in total. The second and third groups each received two different doses of SIB radiotherapy. Patients received whole breast radiotherapy with a simultaneous boost of either lower or higher dose a dose over 3 weeks in total. There was no advantage shown for those who received the higher boost dose it also led to slightly increased rates of side effects.  

Professor of Breast Cancer Clinical Oncology at Cambridge University, NIHR Professor and chief investigator for the trial, Professor Charlotte Coles, said: “Some women have to live with permanent breast changes after radiotherapy which may affect their well-being. With SIB, we can deliver high-quality effective radiotherapy whilst minimising toxicity from it.

“This is a careful step towards even shorter courses of radiotherapy that include more complex techniques. By delivering more targeted boost radiotherapy over shorter time periods, women can get on with their lives more quickly.”

The NIHR-funded FAST Forward trial, which was also led by the ICR-CTSU and reported results in 2020, showed that whole breast radiotherapy could be given over a week. Researchers are now hoping to run another clinical trial to find out if SIB radiotherapy can be delivered to patients requiring a boost in just one week.

Professor Judith Bliss, Professor of Clinical Trials at The Institute of Cancer Research, London,  Director of the Cancer Research UK-funded Clinical Trials and Statistics Unit at the ICR which is managing the IMPORT HIGH trial, said: “For some patients who have a higher risk of seeing their cancer return in the treated breast, delivering an extra, targeted boost of radiotherapy to breast tissue close to the original tumour site is an effective way to lower that risk and help keep cancer from returning to the breast.

“IMPORT HIGH has uncovered how we can streamline our delivery of these radiotherapy boosts – giving them simultaneously with whole breast radiotherapy – without impacting the effectiveness of treatment, or causing patients additional side effects.  We hope this trial will change clinical practice – allowing women to benefit from sophisticated radiotherapy delivery with shorter treatment times and fewer hospital visits.”

The team hope that SIB radiotherapy could reduce the costs for patients travelling to hospital and cut the time taken to undergo treatment and recovery. It could be quickly adopted by the NHS and health systems worldwide as standard radiotherapy equipment is used, freeing up valuable appointment visits that could be used to treat more cancer patients sooner.

Chief Executive of Cancer Research UK, Michelle Mitchell, said: “At a time when health services across the UK are facing chronic staff shortages in cancer services, we need to look at new ways to get more patients treated as quickly as possible. In addition to training up more staff, more precise forms of radiotherapy can help to reduce the number of people who are waiting too long to begin vital treatment.

“Trials like IMPORT HIGH are leading the way in delivering smarter radiotherapy with existing technology. We hope that treatment centres across the UK and globally will rapidly adopt this approach to beat breast cancer sooner and give patients more precious time with their loved ones.”

Helen Lee (46) from Mepal near Cambridge

In October 2013, Helen Lee first noticed an unusual twinge in her right breast and had a hunch that something wasn’t right. Her GP couldn’t feel anything when she examined Helen but referred her to the Breast Unit at Addenbrooke’s Hospital for a mammogram to reassure her.

But, at the young age of 36, Helen was diagnosed with breast cancer. The mammogram revealed a tumour just over 2cm in size located deep in her breast tissue. She remembered:

“I felt quite relieved because I knew there was something wrong. And my surgeon said it was so deep I wouldn’t have felt it. So I was actually really lucky otherwise I would have come in at 51 for screening and it might not have been treatable by then.”

Helen had surgery a few weeks after her diagnosis, followed by a course of chemotherapy. When she was due to begin radiotherapy treatment she was asked if she would like to take part in the IMPORT HIGH trial. Helen was assigned to a group receiving a targeted radiotherapy boost delivered simultaneously during her whole breast radiotherapy treatment, which reduced her treatment from 23 sessions over 4.5 weeks to 15 sessions over 3 weeks.

After undergoing surgery, chemotherapy and radiotherapy treatment, Helen has now been clear of cancer for nearly 10 years. Since her diagnosis and treatment, she has taken part regularly in Cancer Research UK Race for Life, Pretty Muddy and Shine Night Walk events in Cambridge, Bedford and Stamford, fundraising for life-saving research into future treatments for cancer patients.

Reflecting on her cancer journey, Helen said: “One thing that really struck me, at one of the first Cambridge Race for Life events that I did after my diagnosis, was watching the screen on Parker’s Piece where they’re playing the films where the scientists are talking about what they’ve been working on.

“I felt so overwhelmed that all of the people there that day were part of saving my life, and that all the people who took part in trials 10 years ago, 15 years ago, 20 years ago, everything they’ve done meant that I survived my cancer.”

Mission to map the dark Universe sets off on space journey

Euclid space telescope

A European mission to explore how gravity, dark energy and dark matter shaped the evolution of the Universe soared into space today from Cape Canaveral.

The Euclid mission will finally uncover the mysteries of how these ‘dark’ forces have shaped the cosmos that we see today, from life here on Earth, to our Sun, our Milky Way, our nearby galaxy neighbours, and the wider Universe beyondNicholas Walton

The Euclid space telescope will map the “dark Universe” by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky, to gather data on how its structure has formed over its cosmic history.

Led by the European Space Agency (ESA) and a consortium of 2,000 scientists, including from the University of Cambridge, Euclid will spend six years venturing through space with two scientific instruments: a UK-built visible imager (VIS) that will become one of the largest cameras ever sent into space, and a near infrared spectrometer and photometer, developed in France. The mission is supported by funding from the UK Space Agency.

“Watching the launch of Euclid, I feel inspired by the years of hard work from thousands of people that go into space science missions, and the fundamental importance of discovery – how we set out to understand and explore the Universe,” said Chief Executive of the UK Space Agency, Dr Paul Bate. “The UK Space Agency’s investment in Euclid has supported world-class science on this journey, from the development of the ground segment to the build of the crucial visible imager instrument, which will help humanity begin to uncover the mysteries of dark matter and dark energy.”

Euclid took off on board a SpaceX spacecraft from Cape Canaveral in Florida at 4.11pm (BST) on 1 July.

Cambridge’s Institute of Astronomy team has been involved in Euclid since 2010, supporting development of the astrometric calibration pipeline for the optical image data from Euclid, ensuring that the positions of the billions of sources to be imaged by Euclid can be determined to exquisite accuracy.

“Dark energy and dark matter fundamentally govern the formation and evolution of our Universe,” said Dr Nicholas Walton from the Institute of Astronomy. “The Euclid mission will finally uncover the mysteries of how these ‘dark’ forces have shaped the cosmos that we see today, from life here on Earth, to our Sun, our Milky Way, our nearby galaxy neighbours, and the wider Universe beyond.”

The Science and Technology Facilities Council (STFC) also contributed to design and development work on Euclid instrumentation and provided funding to UK astronomy teams who will analyse the data returned from the mission about the physics responsible for the observed accelerated expansion of the Universe. 

“This is a fantastic example of close collaboration between scientists, engineers, technicians, and astronomers across Europe working together to tackle some of the biggest questions in science,” said Mark Thomson, Executive Chair at STFC.

UK Space Agency funding for the Euclid mission is divided between teams at University College London, The Open University, University of Cambridge, University of Edinburgh, University of Oxford, University of Portsmouth and Durham University.

The wider Euclid Consortium includes experts from 300 organisations across 13 European countries, the US, Canada and Japan.

The Environmental Sustainability Team at the University of Cambridge hosted its first-ever Sustainability Showcase on 21st June at Wolfson College.

Departing from the traditional format of separate award ceremonies, the showcase brought together numerous sustainability engagement programs administered by the Environmental Sustainability Team (EST), along with initiatives from other departments within the university.

Dr Sally Pidgeon, Head of Environmental Sustainability at the EST, opened the showcase which celebrated the exceptional efforts of volunteers, staff, and students, with a particular focus on the Green Impact program. 

A total of 43 awards were bestowed for outstanding contributions to sustainability, including an impressive 12 teams that achieved Platinum status. To earn Platinum recognition, teams had to successfully complete 80% of the Green Impact workbook, demonstrating their dedication to sustainable practices. 

The esteemed institutions and teams that attained Platinum status this year included Cambridge University Press and Assessment Cape Town, Cancer Research UK, IMS-MRL, The Department of Obstetrics & Gynaecology, The Green Genies – DPHPC, Christ’s College, Churchill College, Clare College, Gonville & Caius College, Robinson College, St John’s College, and Wolfson College.

Additionally, nine teams achieved Excellence status, which involved undertaking a seven-month project centred around a specific sustainability theme of their choosing. These projects encompassed a wide range of sustainability aspects and addressed various challenges. 

Some notable projects included:

Clean, sustainable fuels made ‘from thin air’ and plastic waste

Carbon capture from air and its photoelectrochemical conversion into fuel with simultaneous waste plastic conversion into chemicals.

Researchers have demonstrated how carbon dioxide can be captured from industrial processes – or even directly from the air – and transformed into clean, sustainable fuels using just the energy from the sun.

We’re not just interested in decarbonisation, but de-fossilisation – we need to completely eliminate fossil fuels in order to create a truly circular economyErwin Reisner

The researchers, from the University of Cambridge, developed a solar-powered reactor that converts captured CO2 and plastic waste into sustainable fuels and other valuable chemical products. In tests, CO2 was converted into syngas, a key building block for sustainable liquid fuels, and plastic bottles were converted into glycolic acid, which is widely used in the cosmetics industry.

Unlike earlier tests of their solar fuels technology however, the team took CO2 from real-world sources – such as industrial exhaust or the air itself. The researchers were able to capture and concentrate the CO2 and convert it into sustainable fuel.

Although improvements are needed before this technology can be used at an industrial scale, the results, reported in the journal Joule, represent another important step toward the production of clean fuels to power the economy, without the need for environmentally destructive oil and gas extraction.

For several years, Professor Erwin Reisner’s research group, based in the Yusuf Hamied Department of Chemistry, has been developing sustainable, net-zero carbon fuels inspired by photosynthesis – the process by which plants convert sunlight into food – using artificial leaves. These artificial leaves convert CO2 and water into fuels using just the power of the sun.

To date, their solar-driven experiments have used pure, concentrated CO2 from a cylinder, but for the technology to be of practical use, it needs to be able to actively capture CO2 from industrial processes, or directly from the air. However, since CO2 is just one of many types of molecules in the air we breathe, making this technology selective enough to convert highly diluted CO2 is a huge technical challenge.

“We’re not just interested in decarbonisation, but de-fossilisation – we need to completely eliminate fossil fuels in order to create a truly circular economy,” said Reisner. “In the medium term, this technology could help reduce carbon emissions by capturing them from industry and turning them into something useful, but ultimately, we need to cut fossil fuels out of the equation entirely and capture CO2 from the air.”

The researchers took their inspiration from carbon capture and storage (CCS), where CO2 is captured and then pumped and stored underground.

“CCS is a technology that’s popular with the fossil fuel industry as a way to reduce carbon emissions while continuing oil and gas exploration,” said Reisner. “But if instead of carbon capture and storage, we had carbon capture and utilisation, we could make something useful from CO2 instead of burying it underground, with unknown long-term consequences, and eliminate the use of fossil fuels.”

The researchers adapted their solar-driven technology so that it works with flue gas or directly from the air, converting CO2 and plastics into fuel and chemicals using only the power of the sun.

By bubbling air through the system containing an alkaline solution, the CO2 selectively gets trapped, and the other gases present in air, such as nitrogen and oxygen, harmlessly bubble out. This bubbling process allows the researchers to concentrate the CO2 from air in solution, making it easier to work with.

The integrated system contains a photocathode and an anode. The system has two compartments: on one side is captured CO2 solution that gets converted into syngas, a simple fuel. On the other plastics are converted into useful chemicals using only sunlight.  

“The plastic component is an important trick to this system,” said co-first author Dr Motiar Rahaman. “Capturing and using CO2 from the air makes the chemistry more difficult. But, if we add plastic waste to the system, the plastic donates electrons to the CO2. The plastic breaks down to glycolic acid, which is widely used in the cosmetics industry, and the CO2 is converted into syngas, which is a simple fuel.”

“This solar-powered system takes two harmful waste products – plastic and carbon emissions – and converts them into something truly useful,” said co-first author Dr Sayan Kar.

“Instead of storing CO2 underground, like in CCS, we can capture it from the air and make clean fuel from it,” said Rahaman. “This way, we can cut out the fossil fuel industry from the process of fuel production, which can hopefully help us avoid climate destruction.”

“The fact that we can effectively take CO2 from air and make something useful from it is special,” said Kar. “It’s satisfying to see that we can actually do it using only sunlight.”

The scientists are currently working on a bench-top demonstrator device with improved efficiency and practicality to highlight the benefits of coupling direct air capture with CO2 utilisation as a path to a zero-carbon future.

The research was supported in part by the Weizmann Institute of Science, the European Commission Marie Skłodowska-Curie Fellowship, the Winton Programme for the Physics of Sustainability, and the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation (UKRI). Erwin Reisner is a Fellow and Motiar Rahaman is a Research Associate of St John’s College, Cambridge. Erwin Reisner leads the Cambridge Circular Plastics Centre (CirPlas), which aims to eliminate plastic waste by combining blue-sky thinking with practical measures.

source: www.cam.ac.uk

‘Lightning McGreen’ and the ‘The Sustainable Hulk’ will lead a new fleet of nine electric buses plying routes travelled by students and staff across the University of Cambridge on the Universal bus route, scheduled to be put into service later this year by bus operator Whippet. 

Alongside the two famed children’s animation and comic book-inspired characters, the names ‘Greenhopper’, ‘Net-Zero Hero’, ‘Pollution Solution’, ‘The Peregreen Falcon’, ‘Eco Eddie’ and ‘The Green Clean Machine’, were also chosen for the fleet from a selection offered by students from the University of Cambridge Primary School in a bus naming competition. 

The competition invited students from the school in the University-built neighbourhood of Eddington to unleash their imagination. Participants were encouraged to consider factors such as the sustainability benefits and innovative features of the new buses in their naming choices. This initiative aimed to engage young minds in a fun and educational way, while also contributing to the enhancement of public transport within the local community.  

Over the past few weeks, the competition captured the attention and enthusiasm of a large number of Eddington school children, attracting well over 100 entries. Their creativity and thoughtfulness were truly remarkable, making the selection process a challenging yet enjoyable task for the judging panel.

The final selection was made by a panel of representatives from the University of Cambridge and Whippet’s parent company, Ascendal Group. The panel carefully evaluated each entry and assessed the names based on originality, relevance, and the potential to resonate with the local community.

“We were overwhelmed by the incredible response from the young participants,” said Nicoletta Gennaro, Ascendal’s Group Head of Marketing. “The names suggested by these talented children were not only impressive but also reflected their deep understanding of our community’s values and aspirations. We are thrilled to involve them in shaping the identity of our new electric buses.”

Winners of the competition received special recognition at a dedicated award ceremony at the University of Cambridge Primary School, where they received prizes from representatives from Whippet and the University.

“We believe that involving the youth in important community projects like this fosters a sense of belonging and ownership,” added Mike Davies, Transport Manager at the University of Cambridge. “Through their contribution, we hope to inspire future generations to actively participate in shaping the development of our city and how we move.”

Both Whippet and the University of Cambridge would like to extend their sincere gratitude to all the participating students and staff at the University of Cambridge Primary School for their invaluable contributions to the competition. The event marks a significant milestone in promoting creativity, community engagement, and the importance of sustainable public transport.

Project launched to provide guidance on research using human stem cell-based embryo models

The University of Cambridge has launched a project to develop the first governance framework for research involving stem cell-based human embryo models in the UK.

We hope that the resulting self-governance framework will enable scientists to proceed with their research with confidence, while maintaining public trust in this vital area of researchKathy Niakan

The Governance of Stem Cell-Based Embryo Models (G-SCBEM) project is led by Cambridge Reproduction and brings together scientists, legal scholars and bioethics experts, as well as representatives from major funders and regulators of this research.

Stem cell-based embryo models (SCBEMs) are three-dimensional structures that mimic aspects of embryo development. They can be created from embryonic stem cells, which can be persuaded to form structures that share a number of features with the embryonic blastocyst stage – the stage at which, in conception, the embryo begins the process of implanting into the uterus.

SCBEMs may offer insight into these critical stages of early development – stages that are normally inaccessible to researchers. They also offer potential for understanding some of the problems that can affect early pregnancies and lead to miscarriage or birth defects. Given that one in four pregnancies is estimated to end in miscarriage, this research has the potential to transform treatments for recurrent miscarriage and to improve the success rates of IVF and other fertility treatments.

Research using human embryos in the UK is tightly regulated by the Human Fertilisation and Embryology Act, which prohibits scientists from culturing human embryos in the lab beyond 14 days.  However, despite the resemblance to human blastocysts (the cluster of cells that forms about five days after an egg is fertilised), SCBEMS are not themselves embryos.  They can be derived from embryonic stem cells but can only form in specific conditions within the laboratory.  Because of this, they do not fall under the remit of the HFE Act. 

Currently there is no dedicated regulatory framework addressing research using SCBEMs, although existing UK law does prohibit them from ever being transferred into a woman’s womb.  Nonetheless, the absence of clear, transparent guidance in this area hinders research and risks damaging public confidence.

Cambridge Reproduction, working in partnership with the Progress Educational Trust (PET), aims to break this deadlock by producing a clear and comprehensive recommended governance framework for research using SCBEMs. As this is an emerging area of research, the team is consulting widely to determine the opportunities, areas of consensus and concerns posed by SCBEMs.

The consultation will also lay the groundwork for engaging the public and other stakeholders in a parallel two-way dialogue around the use of SCBEMs for research and in translation.

“This is a fast-developing area and the project will open important dialogues with researchers, funders, regulators and the general public,” said Professor Kathy Niakan, Chair of Cambridge Reproduction. “We hope that the resulting self-governance framework will enable scientists to proceed with their research with confidence, while maintaining public trust in this vital area of research.”

“Given the similarities that SCBEMs have with human embryos, they offer enormous potential to unlock secrets of early pregnancy,” said Professor Roger Sturmey from Hull York Medical School, Chair of the G-SCBEM Guidelines Working Group. “However, because of these similarities, it is important that scientists working in this field maintain high standards and public confidence and so we hope that a self-governance framework will provide this.”

Sandy Starr, Deputy Director of PET and a member of the G-SCBEM Oversight Group, said, “SCBEMs open up avenues of research that are vitally important for people affected by infertility or genetic conditions. Use of SCBEMs can advance our understanding of human development, disease and reproduction, improving established reproductive technologies while opening up new possibilities. For this research to thrive, it needs to be conducted responsibly and governed in a clear and transparent way, which is where the G-SCBEM project comes in.”

The G-SCBEM guidance will be launched in the late autumn, and will be regularly reviewed to ensure that it keeps pace with new scientific developments.

The G-SCBEM project is funded by grants from the BBSRC Impact Acceleration Account and the University of Cambridge Impact and Knowledge Exchange fund.

Trinity College prayer book belonged to Thomas Cromwell, new research suggests

The Hardouyn Hours, a jewelled fifteenth-century prayer book in Trinity College Library belonged to Thomas Cromwell, chief minister to King Henry VIII, new research has found.

The most exciting Cromwell discovery in a generation – if not more.Tracy Borman

Hever Castle curator, Alison Palmer, recognised the bejewelled, silver gilt binding of Trinity’s Book of Hours from the famous portrait of Thomas Cromwell painted by Hans Holbein the Younger in 1532-3, which hangs in the Frick Collection in New York. Palmer then worked with colleagues Kate McCaffrey and Dr Owen Emmerson to uncover the mystery of the book’s ownership.

The researchers followed a provenance trail that links the book from its donor, Dame Anne Sadleir, directly back to Thomas Cromwell. A team of experts have reviewed the new evidence and are confident that this is the very same book in the Holbein painting and that it belonged to Thomas Cromwell.

The Hardouyn Hours is thought to be the only object from any Tudor portrait to survive to this day.

The team established that the book, printed in Paris by Germain Hardouyn in 1527 or 1528, would have been among the books left by Cromwell to his secretary and protege Ralph Sadleir.

The book came to Trinity from Dame Anne Sadleir who married the grandson of Cromwell’s secretary. Anne was the daughter of the eminent lawyer Sir Edward Coke, a member of Trinity. She donated this Book of Hours, along with Trinity’s best-known manuscript – The Trinity Apocalypse – to the College in 1660.

Trinity’s Librarian Dr Nicolas Bell has collaborated with researchers at Cambridge and beyond to find out more about the Hardouyn Hours.

Based on a note in the front of the book, the gems on the covers and clasps were thought to be jaspers or jacinths, but analysis by Joanna Symonowicz, a doctoral researcher working with Dr Giuliana Di Martino in the University’s Department of Materials Science & Metallurgy, has used Raman spectroscopy to identify them as grossular garnets.

Michèle Bimbenet-Privat, formerly curator of metalwork at the Louvre in Paris, has confirmed that the silver gilt edging was made by Pierre Mangot, goldsmith to King Francis I of France. Mangot, who had moved to Paris the previous year from Blois, also made items for members of the Boleyn family. Mangot’s hallmark is the letter ‘M’ and a lower case ‘a’ tells us that the binding was made between December 1529 and 1530, in Paris, only a year or two after the book was printed.

The Holbein portrait celebrates Cromwell’s appointment as Master of the Jewel House which may explain why the Hardouyn Hours features so prominently.

Dr Nicolas Bell said: “This book of devotional prayers is remarkable for its unusually grand binding, covered with velvet, jewels and highly decorated silver gilt borders, all of which date from the time it was printed and illuminated. It has been enormously exciting to position this luxurious creation in the very centre of the court of Henry VIII, where we know that both Catherine of Aragon and Anne Boleyn owned copies of the very same edition.”

Kate McCaffrey, from Hever Castle, said: “We now believe that Anne Boleyn, Catherine of Aragon, and Thomas Cromwell all owned a copy of the same prayer book… We are confident that this discovery will shed new light on the often-troubled relationship between these giants of the Tudor court.”

Dr Tracy Borman said it was: “The most exciting Cromwell discovery in a generation – if not more.”

Hever Castle recently exhibited Catherine of Aragon’s 1527 prayer book (on loan from the Morgan Library in New York) alongside Anne Boleyn’s 1527 Book of Hours.

The Hardouyn Hours will be on loan to Hever Castle for their exhibition Catherine & Anne: Queens, Rivals, Mothers which runs until 10 November 2023. This is the first time that the book has ever been lent by Trinity College since it was received on 10th August 1660.

DNA discovery highlights how we maintain healthy blood sugar levels after meals

Cola

source: www.cam.ac.uk

A study of the DNA of more than 55,000 people worldwide has shed light on how we maintain healthy blood sugar levels after we have eaten, with implications for our understanding of how the process goes wrong in type 2 diabetes.

What’s exciting about this is that it shows how we can go from large scale genetic studies to understanding fundamental mechanisms of how our bodies workAlice Williamson

The findings, published today in Nature Genetics, could help inform future treatments of type 2 diabetes, which affects around 4 million people in the UK and over 460 million people worldwide.

Several factors contribute to an increased risk of type 2 diabetes, such as older age, being overweight or having obesity, physical inactivity, and genetic predisposition. If untreated, type 2 diabetes can lead to complications, including eye and foot problems, nerve damage, and increased risk of heart attack and stroke.

A key player in the development of the condition is insulin, a hormone that regulates blood sugar – glucose – levels. People who have type 2 diabetes are unable to correctly regulate their glucose levels, either because they don’t secrete enough insulin when glucose levels increase, for example after eating a meal, or because their cells are less sensitive to insulin, a phenomenon known as ‘insulin resistance’.

Most studies to date of insulin resistance have focused on the fasting state – that is, several hours after a meal – when insulin is largely acting on the liver.  But we spend most of our time in the fed state, when insulin acts on our muscle and fat tissues.

It’s thought that the molecular mechanisms underlying insulin resistance after a so-called ‘glucose challenge’ – a sugary drink, or a meal, for example – play a key role in the development of type 2 diabetes. Yet these mechanisms are poorly-understood.

Professor Sir Stephen O’Rahilly, Co-Director of the Wellcome-MRC Institute of Metabolic Science at the University of Cambridge, said: “We know there are some people with specific rare genetic disorders in whom insulin works completely normally in the fasting state, where it’s acting mostly on the liver, but very poorly after a meal, when it’s acting mostly on muscle and fat. What has not been clear is whether this sort of problem occurs more commonly in the wider population, and whether it’s relevant to the risk of getting type 2 diabetes.” 

To examine these mechanisms, an international team of scientists used genetic data from 28 studies, encompassing more than 55,000 participants (none of whom had type 2 diabetes), to look for key genetic variants that influenced insulin levels measured two hours after a sugary drink.

The team identified new 10 loci – regions of the genome – associated with insulin resistance after the sugary drink. Eight of these regions were also shared with a higher risk of type 2 diabetes, highlighting their importance.

One of these newly-identified loci was located within the gene that codes for GLUT4, the critical protein responsible for taking up glucose from the blood into cells after eating. This locus was associated with a reduced amount of GLUT4 in muscle tissue.

To look for additional genes that may play a role in glucose regulation, the researchers turned to cell lines taken from mice to study specific genes in and around these loci. This led to the discovery of 14 genes that played a significant role in GLUT 4 trafficking and glucose uptake – with nine of these never previously linked to insulin regulation.

Further experiments showed that these genes influenced how much GLUT4 was found on the surface of the cells, likely by altering the ability of the protein to move from inside the cell to its surface. The less GLUT4 that makes its way to the surface of the cell, the poorer the cell’s ability to remove glucose from the blood.

Dr Alice Williamson, who carried out the work while a PhD student at the Wellcome-MRC Institute of Metabolic Science, said: “What’s exciting about this is that it shows how we can go from large scale genetic studies to understanding fundamental mechanisms of how our bodies work – and in particular how, when these mechanisms go wrong, they can lead to common diseases such as type 2 diabetes.”

Given that problems regulating blood glucose after a meal can be an early sign of increased type 2 diabetes risk, the researchers are hopeful that the discovery of the mechanisms involved could lead to new treatments in future.

Professor Claudia Langenberg, Director of the Precision Healthcare University Research Institute (PHURI) at Queen Mary University of London and Professor of Computational Medicine at the Berlin Institute of Health, Germany, said: “Our findings open up a potential new avenue for the development of treatments to stop the development of type 2 diabetes. It also shows how genetic studies of dynamic challenge tests can provide important insights that would otherwise remain hidden.”

The research was supported by Wellcome, the Medical Research Council and the National Institute for Health and Care Research.

Limited resources leave school leaders with few options to manage poor behaviour

Boy in school corridor

source: www.cam.ac.uk

School leaders in England feel compelled to continue using a system of escalating punitive measures to manage student behaviour, even though they recognise it fails some pupils, new research suggests.

This is not a call to scrap the existing system, but to consider ways to enhance itLaura Oxley

The findings are from a qualitative study which investigated why more school leaders are not exploring alternative approaches to behaviour management. It argues that resource limitations and other concerns have left teachers feeling trapped within the prevailing system of mounting punishments. Under this, more than a thousand students are excluded, and almost 150,000 suspended, every year.

Educators interviewed for the study often acknowledged the potential benefits of alternative methods, but believed they had little choice but to follow the established orthodoxy. The most common reasons included cost, resource constraints, parental perception, and lack of time.

Most schools in England follow a ‘behaviourist’ approach to student discipline, reinforcing positive behaviour and implementing escalating sanctions for repeated misconduct. Initially, students may receive a verbal warning for poor behaviour, followed by mid-level punishments like detention. Those who persist eventually face suspension and ultimately may be excluded from mainstream education.

The approach seems effective with many students, but there are concerns that it is still failing a significant minority. Government data have, for many years, consistently shown that persistent, disruptive behaviour is the main reason for suspensions or exclusions from school. The latest available figures suggest that about 1,500 students are excluded, and 148,000 suspended, each year for this reason.

The study was conducted by Dr Laura Oxley, now at the Faculty of Education, University of Cambridge, drawing on research she undertook while at the University of York. The newly-published element documents very in-depth interviews with a small group of 14 school leaders in England using a method called Interpretative Phenomenological Analysis. This was just part of the full study, which also surveyed 84 behaviour referral units in England and involved interviews with teachers in other education systems with different approaches to discipline.

Given the scale of the research, the findings should be interpreted cautiously. They do, however, highlight a possible cycle shaping behaviour management policy in England. Specifically, political and resource constraints limit schools’ capacity to experiment with alternative approaches, resulting in scarce evidence for their efficacy. This reinforces the view that the existing model is the only option.

Prior to her academic career Oxley worked with children who were at risk of exclusion from school, their families, and senior school leaders to support schools to provide appropriate educational provision for children who exhibited persistent misconduct. She held roles as an Exclusions and Reintegration Officer in East Yorkshire, and as an Education Inclusion Officer in Cambridgeshire.

“This is not a call to scrap the existing system, but to consider ways to enhance it,” she said. “For significant numbers of children, the current approach isn’t working.”

“Fundamentally, if a child persists with the same behaviour despite multiple punishments, it’s unlikely that they don’t comprehend the consequences. In those situations, instead of escalating the punishment, we should be asking why we aren’t trying something else? Unfortunately, even if school leaders have the motivation to try a different approach, they often feel that they have little choice. This means the same, standardised approach often prevails, even though it doesn’t suit every child.”

Widely-cited alternative behaviour management techniques include ‘restorative practice’ (RP) and ‘collaborative and proactive solutions’ (CPS). RP focuses on rebuilding positive relationships between students, or students and teachers, after breakdowns occur. CPS involves identifying the triggers behind persistent misbehaviour and addressing them collaboratively.

While neither method suits every situation, trials have yielded encouraging results. A 2019 study, for example, found that RP improved behaviour and reduced bullying. Although these approaches are already used by some schools in England, neither is currently used widely.

In Oxley’s study, school leaders identified cost, time and resource constraints as barriers to these alternatives, as they tend to be labour-intensive and require a thorough culture change. Most feared that they would place an intolerable extra burden on already overstretched staff. Issuing sanctions was seen as more efficient. Even providing space for private discussions with challenging students was sometimes considered unfeasible. One teacher explained: “We don’t have the staffing or capabilities for that”.

Some school leaders were concerned that teachers might perceive restorative approaches as a challenge to their authority in the classroom. There is evidence that training can change teachers’ perspectives on handling challenging students, fostering a deeper understanding of the psychological context. Again, however, limited time and resources pose barriers to this, the study suggests.

Participants also expressed unease about parental reactions to alternative approaches. One school leader told Oxley: “A lot of pupils would tell you that it’s harder to do a restorative meeting than it is to miss your break time. It’s more difficult to get the message across to parents.” Some cited cases where heads had been “held to ransom” by parents demanding the exclusion of so-called “problem” pupils.

Oxley suggests these pressures have fostered a culture of risk aversion in schools, impeding potential reforms. “We need to give teachers and parents opportunities to understand the alternatives available,” she said. “The fact that researchers know methods like RP could work in situations where the current approach is not promoting behaviour change is irrelevant if teachers don’t share that confidence.”

The study highlights insufficient promotion of alternative methods in current Government guidance, which prioritises the sanctions-based approach. It emphasises, however, that providing adequate funding and time to enhance teachers’ and parents’ understanding of collaborative and restorative behaviour management techniques is essential to cultivating a “desire for change”.

“At the moment, alternative approaches are often dismissed as unrealistic,” Oxley said. “This stems from a lack of large-scale evidence due to limited opportunities to explore them in schools. Education researchers must address that by studying real experiences in schools, moving beyond limited trials. This will empower more school leaders to see restorative practice and other methods as valuable and viable, generating momentum for change.”

The findings are reported in the Psychology of Education Review.

Early universe crackled with bursts of star formation, Webb Telescope shows

This infrared image from NASA’s James Webb Space Telescope (JWST) was taken for the JWST Advanced Deep Extragalactic Survey, or JADES, programme.

source: www.cam.ac.uk

Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? The James Webb Space Telescope (JWST), a partnership between NASA, the European Space Agency and the Canadian Space Agency, is already providing new insights into this question.

I’m excited that the telescope works so well, allowing us to do such detailed measurements of galaxies that are so distantSandro Tacchella

One of the largest programmes in Webb’s first year of science is the JWST Advanced Deep Extragalactic Survey, or JADES, which will devote about 32 days of telescope time to uncover and characterise faint, distant galaxies. While data is still coming in, JADES has already discovered hundreds of galaxies that existed when the universe was less than 600 million years old. The international team, including researchers from the University of Cambridge, also has identified galaxies sparkling with a multitude of young, hot stars.

The extragalactic research group at the Cavendish Laboratory co-led by Professor Roberto Maiolino and Dr Sandro Tacchella is playing a leadership role in JADES, which is a partnership between the science team of NIRCam — JWST’s primary imager — and NIRSpec — JWST’s primary spectrograph.

In the autumn of 2022, JADES took deep imaging and spectroscopy in and around the iconic Hubble Ultra Deep Field. The JADES imaging is deep, extends further into the infrared, and covers a wider area than any previous imaging with the Hubble Space Telescope. Results based on this data, which have not yet been peer-reviewed, are being reported at the 242nd meeting of the American Astronomical Society in Albuquerque, New Mexico.

“With JADES, we want to answer a lot of questions, like: How did the earliest galaxies assemble themselves? How fast did they form stars? Why do some galaxies stop forming stars?” said Marcia Rieke of the University of Arizona, co-lead of the JADES programme.

For hundreds of millions of years after the big bang, the universe was filled with a gaseous fog. By one billion years after the big bang, the fog had cleared and the universe became transparent, a process known as reionisation. Scientists have debated whether active, supermassive black holes or galaxies full of hot, young stars were the primary cause of reionisation.

As part of the JADES programme, researchers studied these galaxies to look for signatures of star formation – and found them in abundance. “Almost every single galaxy that we are finding shows these unusually strong emission line signatures indicating intense recent star formation. These early galaxies were very good at creating hot, massive stars,” said Ryan Endsley from the University of Texas at Austin.

These bright, massive stars pumped out ultraviolet light, which transformed surrounding gas from opaque to transparent by ionising the atoms, removing electrons from their nuclei. Since these early galaxies had such a large population of hot, massive stars, they may have been the main driver of the reionisation process. The later reuniting of the electrons and nuclei produces distinctively strong emission lines.

The team also found evidence that these young galaxies underwent periods of rapid star formation interspersed with quiet periods where fewer stars formed. These fits and starts may have occurred as galaxies captured clumps of the gaseous raw materials needed to form stars. Alternatively, since massive stars quickly explode, they may have injected energy into the surrounding environment periodically, preventing gas from condensing to form new stars.

Another JADES result released today concerns the structural evolution of galaxies. The team used imaging and spectroscopy data to tackle a key unknown in extragalactic astrophysics, which is how the structural diversity of galaxies we observe today came to be.

The team discovered a galaxy in the infant universe – just 700 million years after the big bang – but with the structure of a far more mature galaxy. The galaxy is 100 times less massive than the Milky Way, but it is highly compact. Most of the young stars of this galaxy are in the outskirts, indicating that this galaxy is growing from the inside out.

“I was surprised to find such a compact galaxy this early in the universe,” said Tacchella, from Cambridge’s Cavendish Laboratory and Kavli Institute for Cosmology. “I’m excited that the telescope works so well, allowing us to do such detailed measurements of galaxies that are so distant.”

Another element of the JADES programme involves the search for the earliest galaxies that existed when the universe was less than 400 million years old. By studying these galaxies, astronomers can explore how star formation in the early years after the big bang was different from what is seen in current times.

The light from faraway galaxies is stretched to longer wavelengths and redder colours by the expansion of the universe – a phenomenon called redshift. By measuring a galaxy’s redshift, astronomers can learn how far away it is and, therefore, when it existed in the early universe. Before Webb, there were only a few dozen galaxies observed above a redshift of 8, when the universe was younger than 650 million years old, but JADES has now uncovered nearly a thousand of these extremely distant galaxies.

The gold standard for determining redshift involves looking at a galaxy’s spectrum, which measures its brightness at closely spaced wavelengths. But a good approximation can be determined by taking photos of a galaxy using filters that each cover a narrow band of colours to get a handful of brightness measurements. In this way, researchers can determine estimates for the distances of many thousands of galaxies at once.

Kevin Hainline of the University of Arizona in Tucson and his colleagues used Webb’s NIRCam (Near-Infrared Camera) instrument to obtain these measurements, called photometric redshifts, and identified more than 700 candidate galaxies that existed when the universe was between 370 million and 650 million years old. The sheer number of these galaxies was far beyond predictions from observations made before Webb’s launch. The observatory’s resolution and sensitivity are allowing astronomers to get a better view of these distant galaxies than ever before.

“Previously, the earliest galaxies we could see just looked like little smudges. And yet those smudges represent millions or even billions of stars at the beginning of the universe,” said Hainline. “Now, we can see that some of them are actually extended objects with visible structure. We can see groupings of stars being born only a few hundred million years after the beginning of time.”

“We’re finding star formation in the early universe is much more complicated than we thought,” said Rieke.

Robot ‘chef’ learns to recreate recipes from watching food videos

Robot ‘chef’ learns to recreate recipes from watching food videos

Researchers have trained a robotic ‘chef’ to watch and learn from cooking videos, and recreate the dish itself.

We wanted to see whether we could train a robot chef to learn in the same incremental way that humans can – by identifying the ingredients and how they go together in the dishGreg Sochacki

The researchers, from the University of Cambridge, programmed their robotic chef with a ‘cookbook’ of eight simple salad recipes. After watching a video of a human demonstrating one of the recipes, the robot was able to identify which recipe was being prepared and make it.

In addition, the videos helped the robot incrementally add to its cookbook. At the end of the experiment, the robot came up with a ninth recipe on its own. Their results, reported in the journal IEEE Access, demonstrate how video content can be a valuable and rich source of data for automated food production, and could enable easier and cheaper deployment of robot chefs.

Robotic chefs have been featured in science fiction for decades, but in reality, cooking is a challenging problem for a robot. Several commercial companies have built prototype robot chefs, although none of these are currently commercially available, and they lag well behind their human counterparts in terms of skill.

Human cooks can learn new recipes through observation, whether that’s watching another person cook or watching a video on YouTube, but programming a robot to make a range of dishes is costly and time-consuming.

“We wanted to see whether we could train a robot chef to learn in the same incremental way that humans can – by identifying the ingredients and how they go together in the dish,” said Grzegorz Sochacki from Cambridge’s Department of Engineering, the paper’s first author.

Sochacki, a PhD candidate in Professor Fumiya Iida’s Bio-Inspired Robotics Laboratory, and his colleagues devised eight simple salad recipes and filmed themselves making them. They then used a publicly available neural network to train their robot chef. The neural network had already been programmed to identify a range of different objects, including the fruits and vegetables used in the eight salad recipes (broccoli, carrot, apple, banana and orange).

Using computer vision techniques, the robot analysed each frame of video and was able to identify the different objects and features, such as a knife and the ingredients, as well as the human demonstrator’s arms, hands and face. Both the recipes and the videos were converted to vectors and the robot performed mathematical operations on the vectors to determine the similarity between a demonstration and a vector.

By correctly identifying the ingredients and the actions of the human chef, the robot could determine which of the recipes was being prepared. The robot could infer that if the human demonstrator was holding a knife in one hand and a carrot in the other, the carrot would then get chopped up.

Of the 16 videos it watched, the robot recognised the correct recipe 93% of the time, even though it only detected 83% of the human chef’s actions. The robot was also able to detect that slight variations in a recipe, such as making a double portion or normal human error, were variations and not a new recipe. The robot also correctly recognised the demonstration of a new, ninth salad, added it to its cookbook and made it.

“It’s amazing how much nuance the robot was able to detect,” said Sochacki. “These recipes aren’t complex – they’re essentially chopped fruits and vegetables, but it was really effective at recognising, for example, that two chopped apples and two chopped carrots is the same recipe as three chopped apples and three chopped carrots.”  

The videos used to train the robot chef are not like the food videos made by some social media influencers, which are full of fast cuts and visual effects, and quickly move back and forth between the person preparing the food and the dish they’re preparing. For example, the robot would struggle to identify a carrot if the human demonstrator had their hand wrapped around it – for the robot to identify the carrot, the human demonstrator had to hold up the carrot so that the robot could see the whole vegetable.

“Our robot isn’t interested in the sorts of food videos that go viral on social media – they’re simply too hard to follow,” said Sochacki. “But as these robot chefs get better and faster at identifying ingredients in food videos, they might be able to use sites like YouTube to learn a whole range of recipes.”

The research was supported in part by Beko plc and the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation (UKRI).

House of moveable wooden walls unveiled, promising a cheaper, greener alternative to ‘knocking through’

Ephemeral exhibit at the London Design Biennale 2023

source: www.cam.ac.uk

Cambridge architects are inviting visitors to the London Design Biennale to experience a prototype home constructed with flexible wooden partition walls which can be shifted to meet the changing needs of residents. The invention aims to reduce waste and carbon while also improving living conditions for those who cannot afford expensive refurbishments.

This is what our cities of the future need – caring for people and the environment at the same timeAna Gatóo

House-owners the world over consider ‘knocking through’ walls to achieve more open-plan living or changing layouts to accommodate new arrivals or circumstances. The results may be impressive, but they come at a sizeable financial and environmental cost. But what if it wasn’t necessary to demolish internal brick and/or plaster walls and build new ones?

Researchers at Cambridge’s Centre for Natural Material Innovation and partners PLP Architecture have just unveiled ‘Ephemeral’, an innovative alternative using engineered wood, at the London Design Biennale at London’s Somerset House (1 – 25 June 2023).

The project, led by Cambridge researcher Ana Gatóo, invites visitors to step into a home constructed around principles of affordability, sustainability, flexibility and adaptation. The flexible wooden partition walls – developed by Gatóo as part of her Cambridge PhD research – are made using kerfing, which allows wood to bend without breaking, the same technique employed in the construction of guitars and other stringed instruments.

The resulting wooden walls are simple, resilient, foldable and movable, meaning they can respond to the changing needs of residents, for instance, as children are born or leave the nest; as age or mobility bring changing requirements; or as homeworking patterns change.

Gatóo says: “Self-assembly and modular furniture have improved so many people’s lives. We’ve developed something similar but for walls so people can take total control of their interior spaces.”

“If you have lots of money, you can hire a designer and alter the interiors of your house, but if you don’t, you’re stuck with very rigid systems that could be decades out-of-date. You might be stuck with more rooms than you need, or too few. We want to empower people to make their spaces their own.”

The team’s ‘rooms of requirement’ provide elegant, affordable solutions which can be built into the fabric of the building from its first design, or seamlessly retrofitted – avoiding the mountains of carbon associated with demolition and reconstruction.

Gatóo says: “We’re using engineered timber, which is affordable and sustainable. It’s a natural material which stores carbon, and when you don’t need it anymore, you can make something else with it. So you are creating minimal waste.”

Gatóo and her colleagues are based in the University’s Centre for Natural Material Innovation, a world leader in research into innovative and sustainable uses of timber in construction.

The team emphasises that their system could be used anywhere in the world, in workplaces as well as in homes, and the researchers have already had encouraging conversations with industry, including with affordable housing developers in India.

Gatóo says: “I’ve worked in development and post-disaster housing with NGOs in many countries around the world, always using sustainable materials. When I started my PhD, I wanted to merge making housing more affordable and social with technical innovation and sustainability. This is what our cities of the future need – caring for people and the environment at the same time.”

Implemented at scale, this innovation could change the construction industry for the better, empowering people to adapt their spaces to their needs while slashing housing costs and overcoming some of the hurdles which the construction industry must tackle to be part of a sustainable future.

Working with Cambridge Enterprise, the research team is seeking industry and policy partners to further advance product feasibility for industry-wide adoption.

The project is supported by PLP Architecture, The Laudes Foundation, the Future Observatory and the AHRC Design Accelerator.

US gun violence: half of people from Chicago witness a shooting by age 40, study suggests

Police line in Chicago, Illinois, USA

source: www.cam.ac.uk

Study following thousands of Chicagoans from across the city over a 25-year period found that 50% of the study participants had seen a shooting before middle age.

A substantial portion of Chicago’s population could be living with trauma as a result of witnessing shootings and homicidesCharles Lanfear

A study tracking the lives of Chicagoans from childhood and adolescence in the 1990s to the start of middle age has found that 56% of Black and Hispanic residents from across the city witnessed at least one shooting by the time they turned 40.

White residents were exposed to gun violence at less than half the rate of Black and Hispanic residents, although it was still high: 25% of White Chicagoans had witnessed a shooting before turning forty.  

Across racial categories, 50% of all the study’s participants had been exposed to gun violence by age 40. The average age to witness a shooting was just 14 years old.  

Of those in the study, more than 7% of Black and Hispanic people had themselves been shot before turning forty, compared to 3% of White people. The average age for being shot was 17 years old.

Researchers also compared the locations of gun violence incidents* in the year leading up to recent study interviews in 2021. Rates of shootings within a 250-metre radius of the homes of Black participants were over 12 times higher than those of White participants. Rates of shootings near the homes of Hispanic people were almost four times higher than for White people.

The research team continued to gather data for participants who had moved out of the city, although the vast majority of gun violence took place within Chicago. 

The sustained stress of living with the potential for gun violence likely takes a “cumulative physiological toll” on Chicago’s citizens – and people in cities across the US, argue researchers.

Findings from the latest study, led by a University of Cambridge criminologist in collaboration with researchers from Harvard and Oxford universities, are published in JAMA Network Open, a journal of the American Medical Association

“Existing evidence suggests that the long-term stress of exposure to firearm violence can contribute to everything from lower test scores for schoolkids to diminished life expectancy through heart disease,” said study lead author Dr Charles Lanfear, from the University of Cambridge’s Institute of Criminology.

“We expected levels of exposure to gun violence to be high, but not this high. Our findings are frankly startling and disturbing,” said Lanfear. “A substantial portion of Chicago’s population could be living with trauma as a result of witnessing shootings and homicides, often at a very young age.”

“It is clear that Black people in particular are often living in a very different social context, with far higher risks of seeing and becoming victims of gun violence in the streets near their homes lasting into middle age.”

The Project on Human Development in Chicago Neighborhoods (PHDCN), a Harvard University study, has followed thousands of children since they were first surveyed in the 1990s, gathering life experiences as they grow up in the city or move away. Participants are from households selected at random from a set list of eighty Chicago districts – carefully chosen to reflect Chicago’s spectrum of race and levels of social advantage, or lack thereof.   

The latest research focused on data gathered from 2,418 of participants born in the early 1980s through to the mid-1990s, equally split between men and women.**   

The oldest study participants, born in 1981, hit adolescence in the early-to-mid 1990s when lethal violence reached a peak in the US. “The nineties saw a demographic bump collide with high poverty levels and rises in gang crime resulting in part from the crack epidemic,” said Lanfear.

“However, since 2016 we have seen another surge in gun violence. Rates of fatal shootings in Chicago are now higher than they ever were in the nineties.”

Men are far more likely to be involved in violent crime, and this is reflected in the risks of actually being shot by age 40, which are five times higher for men than women. However, there was a much smaller difference between the sexes for exposure to gun violence: 43% of women and 58% of men had seen someone shot.

“The chronic stress effects on women from being so highly exposed to firearm violence may well be substantial in Chicago, and indeed in many US cities,” said Lanfear.

“The study participants are taken from right across Chicago, and only a tiny fraction will be involved in any kind of crime. Given the levels of women and children witnessing gun violence in the city, the vast majority of this exposure will be as bystanders in public spaces, in streets or outside schools.”    

“The public health consequences of life in violent and traumatised neighbourhoods will be playing out not just in Chicago, but in many cities right across the United States,” Lanfear said.


Notes

*Taken from the Gun Violence Archive, and not-for-profit organisation that collates data on gun violence drawn from sources including police departments, media and government agencies.
** Racial make-up of the study participants as follows: 890 Black respondents, 1146 Hispanic respondents, and 382 White respondents. The research looked at data from PHDCN study groups born in 1984, 1987 and 1996. The research team say they can safely estimate exposure to gun violence up to age 40 for the majority of the study participants. Even the younger group, now 27, are on track to compare with older cohorts, as most shootings are witnessed during youth.

The King breaks ground on Cambridge’s New Whittle Laboratory

His Majesty The King visited the University of Cambridge today, in his first public engagement following the Coronation.

His Majesty was in Cambridge to break ground on the New Whittle Laboratory, where he also met with staff and researchers, leaders from the aviation industry and senior government representatives.

The New Whittle Laboratory, a £58 million facility, will be the leading global centre for net zero aviation and energy. Its mission is to halve the time to develop key technologies to support a sustainable aviation industry.

Alongside the ground-breaking, senior figures from government and industry gathered for an international roundtable as part of an initiative led by Cambridge and MIT. This will present insights based on global aviation systems modelling capabilities developed through the Aviation Impact Accelerator, a project led by the Whittle Laboratory and the Cambridge Institute for Sustainability Leadership.

Today, it typically takes six to eight years to develop a new technology to a point where it can be considered for commercial deployment in the aerospace and energy sectors, recent trials in the Whittle Laboratory have shown this timeframe can be accelerated by breaking down barriers that exist between academia and industry.

The New Whittle Laboratory will incorporate the Bennett Innovation Laboratory – made possible through a philanthropic gift from the Peter Bennett Foundation – to bring together a critical mass of talent, giving them the right skills, tools, culture and working environment to solve complex multidisciplinary challenges. It will also be home to the UK’s National Centre for Propulsion and Power, built around a fast feedback model pioneered in Formula One, to cut the time to develop technologies from years to months.

Participating organisations in the roundtable included the UK Government, UK Aerospace Technology Institute, the US Federal Aviation Administration, NASA, EU Clean Aviation Joint Undertaking, Airbus, Boeing, Rolls-Royce, and the Sustainable Markets Initiative.

As The Prince of Wales, His Majesty previously visited the Whittle Laboratory in January 2020, and March 2022, to encourage the acceleration of sustainable aviation, as well as hosting an industry roundtable in February 2020 in London with the Sustainable Markets Initiative and World Economic Forum to explore solutions for decarbonising air travel.

Professor Rob Miller, Director of the Whittle Laboratory, said:

“We need to completely transform the innovation landscape in the aviation and energy sectors if we are to reach net zero by 2050. The new Whittle Lab has been designed as a disruptive innovation laboratory targeting the critical early stages in the lifecycles of technologies, where there are windows of opportunity to translate scientific strengths into global technological and industrial leadership.

“The Lab is designed to work at the intersection of cutting-edge science and emerging engineering applications, providing fast feedback between the two, and dramatically cutting the time to deliver zero-emission technologies.”

Grant Shapps, the UK Government’s Energy Security Secretary, said:

“The UK is leading a revolution in aviation, looking to new technologies to cut emissions.

“Having established the Jet Zero Council three years ago by bringing together government, industry and academia, I strongly welcome the Whittle Laboratory being at the forefront of that endeavour today.

“This will further help the best minds from the fields of energy and aviation push ever-further and faster with the latest innovations in order to solve the problem of environmentally friendly and affordable flying.”

Mark Harper, the UK Government’s Transport Secretary, said:

“Having already invested £165 million into the production of sustainable aviation fuels, this Government is determined to harness the economic benefits of flying while supporting industry and academia to create cleaner skies for the future.”

“The breaking ground of Whittle Laboratory is great news for the UK’s world-leading aviation sector, representing another step towards the UK hitting our Jet Zero goals.”

Peter Bennett, University of Cambridge alumnus, philanthropist and founder of the Peter Bennett Foundation, said:

“To tackle the most complex challenges, we need to take a whole systems approach, where innovative technologies can be explored within the context of the realities that may impact their roll out. Rigorous testing using models such as the Aviation Impact Accelerator expedites the process of innovation and implementation.

“We need new ways to work together at speed, which is why the Bennett Innovation Lab will bring together global experts from government, industry and academia, enabling  radical collaboration. I believe by using Cambridge’s convening power, this can make a real difference, fast.”

Grazia Vittadini, Chief Technology Officer at Rolls-Royce, said:  

“The Whittle Laboratory and Rolls-Royce have worked together for 50 years. Over this time the partnership has delivered hundreds of technologies into Rolls-Royce products. Deep technology partnerships like this are critical if the UK is to maintain its role as a science superpower and to create high value jobs in the UK. The New Whittle Laboratory offers an exciting opportunity to raise this ambition by bringing together cutting-edge science and engineering application in one building with the aim of meeting the challenge of net zero flight by 2050.”

Jim Hileman, Vice President and Chief Engineer, Sustainability and Future Mobility at Boeing said:

“Boeing’s partnership with the University of Cambridge is central to the effort of making aviation carbon neutral. As well as helping us to find technology solutions, it is bringing together different companies and academic disciplines from across the sector to drive change at the system level. We are excited by the way in which the New Whittle Laboratory has been designed to break down silos, bringing together a wide range of disciplines to take on the most challenging net zero aviation problems.”

Eisaku Ito, Chief Technology Officer at Mitsubishi Heavy Industries, said:

“At Mitsubishi Heavy Industries we have a goal to achieve carbon neutrality by 2040, through our Mission Net Zero initiative. But we know that we can only reach this through accelerating the pace of innovation, and scaling up the development of net zero technologies. We have benefited from a strategic research partnership with the Whittle Laboratory since the 1980s, so we are excited to see work begin on this new facility that will become an important global centre for collaboration and disruptive innovation.

“We look forward to continuing our relationship with the Whittle Laboratory over the coming decades, and we want our engineers to think of the new Lab as their European home – a unique environment where they can participate in a culture that brings together the best global ideas, expertise, software, tools and testing facilities that can help solve the challenge of climate change.”

It is a great honour to have our Black Pine included as part of the choreographed display.Beverley Glover, CUBG Director

As part of the weekend of Coronation celebrations, 10 locations around the UK including Cambridge University Botanic Garden – as well as landmarks in Blackpool, Sheffield, Cardiff, Edinburgh, Newcastle and Gateshead, Cornwall and Belfast – were lit up in a stunning live sequence called Lighting Up The Nation.

Billed by the BBC as ‘a truly spectacular part of the Coronation Concert… a very special moment for people all across the country to come together in celebration’, the event showcased the country’s diverse cultural heritage in music, theatre and dance, with the amazing light display as a stunning centrepiece using projections, drones, laser displays and illuminations to bring iconic locations to life.

The majestic Pinus nigra tree, which forms part of the Garden’s iconic tree collection, is located along the Garden’s Main Walk and helps form the backbone of the Heritage Landscape. On the evening of Sunday 7 May the tree and surrounding landscape was seen as never before – dressed in a stunning display of 12,500 lights, powered by 25 eco-bikes, ridden by Cambridge University students, Garden staff and volunteers to create a kinetic power display to highlight the King’s commitment to green energy and conservation.

Beverley Glover, CUBG Director, said: “It is a great honour to have been selected as one of 10 iconic locations to form the centrepiece of Lighting up the Nation, broadcast live from Windsor Castle, and to have our Black Pine included as part of the choreographed display.

“CUBG’s tree collection dates back to the founding of the Garden on this site and is the vision of our founder and Charles Darwin’s mentor – John Stevens Henslow. The Pinus nigra, Black Pine, is one of the first Garden plantings and it is interesting because it was selected by Henslow to demonstrate how plants even within the same species can be different. Some species of Black Pine from warm climates hold their branches erect, while Black Pines from cold areas, have sloping branches to allow snow to slide off them to limit the snow load on their branches and ensure the leaves are free to photosynthesise.”

Ice sheets can collapse faster than previously thought possible

Sentinel-1 image composite depicting the highly fractured and fast-flowing frontal margin of the Thwaites and Crosson ice shelves

source: www.cam.ac.uk

Ice sheets can retreat up to 600 metres a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured.

An international team of researchers used high-resolution imagery of the seafloor to reveal just how quickly a former ice sheet that extended from Norway retreated at the end of the last Ice Age, about 20,000 years ago. 

The team, including researchers from the University of Cambridge, mapped more than 7,600 small-scale landforms called corrugation ridges across the seafloor. The ridges are less than 2.5 metres high and are spaced between about 25 and 300 metres apart.

These landforms are understood to have formed when the ice sheet’s retreating margin moved up and down with the tides, pushing seafloor sediments into a ridge every low tide. Given that two ridges would have been produced each day, the researchers were able to calculate how quickly the ice sheet retreated.

Their results, reported in the journal Nature, show the former ice sheet underwent pulses of rapid retreat at a speed of 50 to 600 metres per day. This is much faster than any ice sheet retreat rate that has been observed from satellites or inferred from similar landforms in Antarctica.

“Our research provides a warning from the past about the speeds that ice sheets are physically capable of retreating at,” said Dr Christine Batchelor from Newcastle University, who led the research. “Our results show that pulses of rapid retreat can be far quicker than anything we’ve seen so far.”

Information about how ice sheets behaved during past periods of climate warming is important to inform computer simulations that predict future ice sheet and sea-level change. 

“This study shows the value of acquiring high-resolution imagery about the glaciated landscapes that are preserved on the seafloor,” said co-author Dr Dag Ottesen from the Geological Survey of Norway, who is involved in the MAREANO seafloor mapping programme that collected the data.

The new research suggests that periods of such rapid ice-sheet retreat may only last for short periods of time: from days to months.

“This shows how rates of ice-sheet retreat averaged over several years or longer can conceal shorter episodes of more rapid retreat,” said co-author Professor Julian Dowdeswell from Cambridge’s Scott Polar Research Institute. “It is important that computer simulations are able to reproduce this ‘pulsed’ ice-sheet behaviour.”

The seafloor landforms also shed light into the mechanism by which such rapid retreat can occur. The researchers found that the former ice sheet had retreated fastest across the flattest parts of its bed.

“An ice margin can unground from the seafloor and retreat near-instantly when it becomes buoyant,” said co-author Dr Frazer Christie, also from the Scott Polar Research Institute. “This style of retreat only occurs across relatively flat beds, where less melting is required to thin the overlying ice to the point where it starts to float.”

The researchers conclude that pulses of similarly rapid retreat could soon be observed in parts of Antarctica. This includes at West Antarctica’s vast Thwaites Glacier, which is the subject of considerable international research due to its potential susceptibility to unstable retreat. The authors of this new study suggest that Thwaites Glacier could undergo a pulse of rapid retreat because it has recently retreated close to a flat area of its bed.

“Our findings suggest that present-day rates of melting are sufficient to cause short pulses of rapid retreat across flat-bedded areas of the Antarctic Ice Sheet, including at Thwaites”, said Batchelor. “Satellites may well detect this style of ice-sheet retreat in the near future, especially if we continue our current trend of climate warming.”

Medieval monks accidentally recorded some of history’s biggest volcanic eruptions

By observing the night sky, medieval monks unwittingly recorded some of history’s largest volcanic eruptions, according to a new analysis of 12th and 13th century European and Middle Eastern chronicles.

An international team, including researchers from the University of Cambridge, drew on readings of medieval texts, along with ice core and tree ring data, to accurately date some of the biggest volcanic eruptions the world has ever seen. Their results, reported in the journal Nature, uncover new information about one of the most volcanically active periods in Earth’s history, which some think helped to trigger the Little Ice Age, a long interval of cooling that saw the advance of European glaciers.

It took the researchers, led by the University of Geneva (UNIGE), almost five years to examine hundreds of annals and chronicles from across Europe and the Middle East, in search of references to total lunar eclipses and their colouration.

Total lunar eclipses occur when the moon passes into the Earth’s shadow. Typically, the moon remains visible as a reddish orb because it is still bathed in sunlight bent round the Earth by its atmosphere. But after a very large volcanic eruption, there can be so much dust in the stratosphere – the middle part of the atmosphere starting roughly where commercial aircraft fly – that the eclipsed moon almost disappears.

Medieval chroniclers recorded and described all kinds of historical events, including the deeds of kings and popes, important battles, and natural disasters and famines. Just as noteworthy were the celestial phenomena that, to the chroniclers, might foretell such calamities. Mindful of the Book of Revelation, a vision of the end times that speaks of a blood-red moon, the monks were especially careful to take note of the moon’s colouration.

Of the 64 total lunar eclipses that occurred in Europe between 1100 and 1300, the chroniclers had faithfully documented 51. In five of these cases, they also reported that the moon was exceptionally dark.

Asked what made him connect the monks’ records of the brightness and colour of the eclipsed moon with volcanic gloom, the lead author of the work, UNIGE’s Sébastien Guillet said: “I was listening to Pink Floyd’s Dark Side of the Moon album when I realised that the darkest lunar eclipses all occurred within a year or so of major volcanic eruptions. Since we know the exact days of the eclipses, it opened the possibility of using the sightings to narrow down when the eruptions must have happened.”

The researchers found that scribes in Japan took equal note of lunar eclipses. One of the best known, Fujiwara no Teika, wrote of an unprecedented dark eclipse observed on 2 December 1229: ‘the old folk had never seen it like this time, with the location of the disk of the Moon not visible, just as if it had disappeared during the eclipse… It was truly something to fear.’

The stratospheric dust from large volcanic eruptions was not only responsible for the vanishing moon. It also cooled summer temperatures by limiting the sunlight reaching the Earth’s surface. This in turn could bring ruin to agricultural crops.

“We know from previous work that strong tropical eruptions can induce global cooling on the order of roughly 1°C over a few years,” said Markus Stoffel from the University of Geneva, a specialist in converting measurements of tree rings into climate data, who co-designed the study. “They can also lead to rainfall anomalies with droughts in one place and floods in another.”

Despite these effects, people at the time could not have imagined that the poor harvests or the unusual lunar eclipses had anything to do with volcanoes – the eruptions themselves were all but one undocumented.

“We only knew about these eruptions because they left traces in the ice of Antarctica and Greenland,” said co-author Professor Clive Oppenheimer from Cambridge’s Department of Geography. “By putting together the information from ice cores and the descriptions from medieval texts we can now make better estimates of when and where some of the biggest eruptions of this period occurred.”

To make the most of this integration, Guillet worked with climate modellers to compute the most likely timing of the eruptions. “Knowing the season when the volcanoes erupted is essential, as it influences the spread of the volcanic dust and the cooling and other climate anomalies associated with these eruptions,” he said.

As well as helping to narrow down the timing and intensity of these events, what makes the findings significant is that the interval from 1100 to 1300 is known from ice core evidence to be one of the most volcanically active periods in history. Of the 15 eruptions considered in the new study, one in the mid-13th century rivals the famous 1815 eruption of Tambora that brought on ‘the year without a summer’ of 1816. The collective effect of the medieval eruptions on Earth’s climate may have led to the Little Ice Age, when winter ice fairs were held on the frozen rivers of Europe.

“Improving our knowledge of these otherwise mysterious eruptions, is crucial to understanding whether and how past volcanism affected not only climate but also society during the Middle Ages,” said Guillet.

The research was supported in part by the Swiss National Science Foundation.

A new image reveals the most detailed map of dark matter distributed across a quarter of the entire sky, reaching deep into the cosmos.

We have mapped the invisible dark matter across the sky to the largest distances, and clearly see features of this invisible world that are hundreds of millions of light-years acrossBlake Sherwin

The findings, from the Atacama Cosmology Telescope collaboration involving researchers from the University of Cambridge, provide further support to Einstein’s theory of general relativity, which has been the foundation of the standard model of cosmology for more than a century. The results offer new methods to demystify dark matter, the unseen mass thought to account for 85% of the matter in the universe.

For millennia, humans have been fascinated by the mysteries of the cosmos. From ancient civilisations such as the Babylonians, Greeks, and Egyptians to modern-day astronomers, the allure of the starry sky has inspired countless quests to unravel the secrets of the universe.

And although models that explain the cosmos have existed for centuries, the field of cosmology, where scientists use quantitative methods to understand the evolution and structure of the universe, is relatively new—having only formed in the early 20th century with the development of Albert Einstein’s theory of general relativity. 

Now, a set of papers submitted to The Astrophysical Journal by researchers from the Atacama Cosmology Telescope (ACT) collaboration has produced a new image that reveals the most detailed map of matter distributed across a quarter of the entire sky, reaching deep into the cosmos. It confirms Einstein’s theory about how massive structures grow and bend light, with a test that spans the entire age of the universe.

“We have mapped the invisible dark matter across the sky to the largest distances, and clearly see features of this invisible world that are hundreds of millions of light-years across,” said co-author Professor Blake Sherwin from Cambridge’s Department of Applied Mathematics and Theoretical Physics, where he leads a group of ACT researchers. “It looks just as our theories predict.”

Although dark matter makes up a large chunk of the universe and shaped its evolution, it has remained hard to detect because it doesn’t interact with light or other forms of electromagnetic radiation. As far as we know, dark matter only interacts with gravity. 

To track it down, the more than 160 collaborators who have built and gathered data from the National Science Foundation’s Atacama Cosmology Telescope in the high Chilean Andes observe light emanating following the dawn of the universe’s formation, the Big Bang—when the universe was only 380,000 years old. Cosmologists often refer to this diffuse light that fills our entire universe as the “baby picture of the universe,” but formally, it is known as the cosmic microwave background radiation (CMB).

The team tracks how the gravitational pull of large, heavy structures including dark matter warps the CMB on its 14-billion year journey to us, like how a magnifying glass bends light as it passes through its lens.

“We’ve made a new mass map using distortions of light left over from the Big Bang,” said Mathew Madhavacheril from the University of Pennsylvania, lead author of one of the papers. “Remarkably, it provides measurements that show that both the ‘lumpiness’ of the universe, and the rate at which it is growing after 14 billion years of evolution, are just what you’d expect from our standard model of cosmology based on Einstein’s theory of gravity.” 

“Our results also provide new insights into an ongoing debate some have called ‘The Crisis in Cosmology’,” said Sherwin. This crisis stems from recent measurements that use a different background light, one emitted from stars in galaxies rather than the CMB. These have produced results that suggest the dark matter was not lumpy enough under the standard model of cosmology and led to concerns that the model may be broken. However, the team’s latest results from ACT were able to precisely assess that the vast lumps seen in this image are the exact right size. 

“When I first saw them, our measurements were in such good agreement with the underlying theory that it took me a moment to process the results,” said Cambridge PhD candidate Frank Qu, lead author of one of the new papers. “But we still don’t know what the dark matter is, so it will be interesting to see how this possible discrepancy between different measurements will be resolved.”

“The CMB lensing data rivals more conventional surveys of the visible light from galaxies in their ability to trace the sum of what is out there,” said Suzanne Staggs from Princeton University, Director of ACT. “Together, the CMB lensing and the best optical surveys are clarifying the evolution of all the mass in the universe.” 

“When we proposed this experiment in 2003, this measurement wasn’t even on our agenda; we had no idea the full extent of information that could be extracted from our telescope,” said Mark Devlin, from the University of Pennsylvania, Deputy Director of ACT. “We owe this to the cleverness of the theorists, the many people who built new instruments to make our telescope more sensitive, and the new analysis techniques our team came up with.”

With ACT having been decommissioned in late 2022, further papers highlighting some of the other final results are slated for submission in the coming year. Observations will continue at the site with the Simons Observatory, including a new telescope due to begin in 2024 that can map the sky almost ten times faster.

The pre-print articles highlighted in this release are available on act.princeton.edu and will appear on the open-access arXiv.org. They have been submitted to The Astrophysical Journal
