Hepatitis cases in children linked to adeno-associated virus AAV2
Recent acute hepatitis cases of unknown origin in children have now been linked to the virus AAV2 in two new UK studies, with no evidence of a direct link to SARS-CoV-2 infection. Submitted to MedRxiv as pre-prints, both studies found that the common virus AAV2 (adeno-associated virus 2) was present at high levels in all samples from patients with unexplained hepatitis.

Self-reflection linked to improved late-life cognition and brain health
Self-reflection linked to improved late-life cognition and brain health
Self-reflection is positively associated with cognition late in life as well as glucose metabolism, a marker of brain health, finds a new study led by UCL researchers. The authors of the new study, published in Neurology , say that older adults who engage in self-reflection may have a reduced risk of dementia.

Lonely old deers: ageing red deer become less social as they grow older
Lonely old deers: ageing red deer become less social as they grow older
A new social network analysis of female wild red deer on the Isle of Rum in Scotland shows that ageing deer tend to adopt a life of solitude in their advancing years. A multidisciplinary team led by researchers from the Universities of Oxford and Edinburgh has found that wild red deer become less sociable with age.

Novel way to 'see' the first stars through the fog of the early Universe
Novel way to ’see’ the first stars through the fog of the early Universe
A team of astronomers has developed a method that will allow them to -see- through the fog of the early Universe and detect light from the first stars and galaxies. The first stars were surrounded by clouds of hydrogen, which absorb light really well, so it's hard to detect or observe the light behind the clouds directly.

Shift workers ’can’t all adjust to a night shift’: new research
Sleep quality and circadian rhythms in night shift workers was found to be poorer than in those who worked day shifts University of Warwick study fitted hospital workers with wearable tech to monitor physical activity and body temperature day and night Workers would still show these effects even if they had been working the night shift for years before, suggesting that they do not adjust over time Scientists at the University of Warwick, jointly

No evidence that depression is caused by low serotonin levels, finds comprehensive review
After decades of study, there remains no clear evidence that serotonin levels or serotonin activity are responsible for depression, according to a major review of prior research led by UCL scientists. The new umbrella review - an overview of existing meta-analyses and systematic reviews - published in Molecular Psychiatry , suggests that depression is not likely caused by a chemical imbalance, and calls into question what antidepressants do.

Calls for opioid agonist treatments to be used in the treatment of injecting-related infections
Calls for opioid agonist treatments to be used in the treatment of injecting-related infections
Medications such as buprenorphine and methadone should be used to help treat patients with opioid use disorder who come to hospital with injecting-related infections, finds new research from UCL and UNSW, Sydney. Injecting-related bacterial and fungal infections are an increasingly common causes of pain, disability, and death among people who inject drugs.

Chemical production breakthrough could make £9bn industry greener and cleaner
Researchers at a Scottish university have found a greener, cleaner way to produce a common chemical relied on by multibillion-dollar industries. In a new paper published today in the journal Cell Reports Physical Science , researchers from the University of Glasgow demonstrate a new method of creating anilines - chemicals commonly used in the manufacture of products including dyes, plastics and insulation, and pharmaceuticals like paracetamol.

More children aged 8-17 trying to lose weight than a decade ago, including children of a healthy weight
Over a quarter (26.5%) of children reported trying to lose weight between 2015 and 2016, a 5% increase over 1997 and 1998, finds new research from the University of Oxford. The largest increases in weight loss attempts were seen in boys, older children, Asian children, and children from lower income households, according to the study published today in the Archives of Disease in Childhood.

Research project lends helping human hand to AI decisionmakers
A new research project is setting out to help artificial intelligence systems make fairer choices by lending them a helping human hand. Researchers from the University of Glasgow and Fujitsu Ltd. have teamed up for the year-long collaboration, which is called 'End-users fixing fairness issues', or Effi.

Scientists shed new light on how SARS-CoV-2 evades the immune response in early infection
Scientists shed new light on how SARS-CoV-2 evades the immune response in early infection
A new study led by Cardiff University has shed light on how the COVID-19 virus "interferes" with the body's initial immune response to avoid detection. In the lab scientists showed how SARS-CoV-2 can evade natural killer (NK) cells - a type of white blood cell and a crucial part of the early immune response - by shutting off several ways these cells recognise the virus.

Covid infection doubles risk of mental health and financial problems in older adults
Adults over the age of 52 appear to be twice as likely to develop mental health problems such as depression and anxiety, alongside suffering from financial difficulties after contracting Covid-19, finds a new UCL-led study. The study, published in  PNAS , used data from 5,146 adults between the ages of 52 and 74 who participated in the English Longitudinal Study of Ageing, to examine the immediate and longer-term impact of Covid-19 infection on the mental health, wellbeing, social interactions, and financial outcomes of older adults.

Asteroid impacts create diamond materials with exceptionally complex structures
Asteroid impacts create diamond materials with exceptionally complex structures
Shockwaves caused by asteroids colliding with Earth create materials with a range of complex carbon structures, which could be used for advancing future engineering applications, according to an international study led by UCL and Hungarian scientists. Published today in  Proceedings of the National Academy of Sciences , the team of researchers found that diamonds formed during a high-energy shock wave from an asteroid collision around 50,000 years ago have unique and exceptional properties, caused by the short-term high temperatures and extreme pressure.

Opinion: Obesity - neither genetics nor social background is a very good predictor of body weight
Writing in The Conversation, Dr David Bann and Liam Wright (IOE, UCL's Faculty of Education and Society) and Neil Davies (University of Bristol) explore the connection between genetics and social background and body weight in adulthood. There's long been a debate about whether genetics or the environment people are raised in is the biggest cause of obesity.

Elephant genes could hold the key to avoiding cancers
Elephant genes could hold the key to avoiding cancers
Scientists modelling the cancer-suppressing p53 gene identify how the 20 different molecules unique to elephants get activated for increased sensitivity and response against carcinogenic conditions - with implications for cancer treatments in humans. Scientists from seven research institutions including the University of Oxford and the University of Edinburgh have used pioneering bioinformatic modelling to investigate the molecular interactions of the p53 protein known to give protection against cancers.

Early life infection increases sensitivity to pain in newborn babies
Researchers from Oxford's Department of Paediatrics have discovered that infection can increase a baby's sensitivity to pain, which may last longer than the infection. In a new study published in Nature Communications , researchers observed 65 newborn babies who had received a standard heel-prick blood test to look for signs of potential infection.
