Analysis: Coronavirus mutations - what we’ve learned so far
Dr Lucy van Dorp (UCL Genetics, Evolution & Environment) explains the mutations that Covid-19 is undergoing and how we're still facing fundamentally the same virus as we were at the start of the pandemic. In early January, the first genome sequence of Sars-CoV-2 - the virus that causes Covid-19 - was released under the moniker "Wuhan-1".

Placenta is initiated first, as cells of a fertilised egg divide and specialise
The first stages of placental development take place days before the embryo starts to form in human pregnancies. This new finding highlights the importance of healthy placental development in pregnancy, and could lead to future improvements in fertility treatments such as IVF, and a better understanding of placental-related diseases in pregnancy.

Predatory bacteria escape unharmed from prey cell using unique tool - study
Predatory bacteria, capable of invading and consuming harmful bugs such as E.coli and Salmonella, use a unique tool to help them escape the cell they have invaded without harming themselves, according to a new study. Researchers at the Universities of Birmingham and Nottingham have identified a particular enzyme used by the bacteria to rupture the cell wall of its prey bacteria and exit without damaging its own cell wall.

Chromium steel was first made in ancient Persia
Chromium steel - similar to what we know today as tool steel - was first made in Persia, nearly a millennium earlier than experts previously thought, according to a new study led by UCL. The discovery, published in the Journal of Archaeological Science , was made with the aid of a number of medieval Persian manuscripts, which led the researchers to an archaeological site in Chahak, southern Iran.

Do rats like to be tickled?
Not all rats like to be tickled but by listening to their vocalisations it is possible to understand in real-time their individual emotional response, according to new research by the University of Bristol. The study, published today [21 September] in Current Biology, suggests that if this same relationship is observed for other situations, then it may be possible to use call patterns in rats to measure their emotional response and understand how best to improve their welfare.

An international team of astronomers, including researchers from the University of Cambridge, has discovered a new class of planet, an 'ultrahot Neptune', orbiting the nearby star LTT 9779. This planet is particularly exciting because of its peculiarity: how did this planet come to arrive on such a short period orbit and why does it still possess an atmosphere? Ed Gillen The planet orbits so close to its star that its year lasts only 19 hours, and stellar radiation heats the planet to over 1700 degrees Celsius.
Homicides near schools affect students’ educational outcomes says new study
Homicides near schools negatively impact on the educational attainment of children, a new study in the Journal of Labor Economics reports. During this unique study, researchers from the University of Birmingham and University of Surrey investigated if exposure to homicides had an impact on the educational outcomes of children in schools close by.

Life reconstruction of Euparkeria highlighting the body parts investigated in this study. Illustration: Oliver Demuth. The oblique ankle joint did not allow Euparkeria to assume a fully upright posture as the foot also turns medially when the ankle joint is extended. An ankle joint allowing a more upright posture evolved later independent from the hip structure.
Five things we’re doing to help prevent the spread of Covid-19
Our ground breaking research has never been so critical during the Covid-19 pandemic. Amongst other things, we're helping to detect the virus, support people suffering from the effects of lockdown and understand how we could be better prepared if there was another pandemic. Here are five things our researchers have done to help prevent the spread of Covid-19.

Hospitals miss mental illness diagnosis in more than a quarter of patients
Severe mental illness diagnoses are missed by clinicians in more than one quarter of cases when people are hospitalised for other conditions, finds a new study led by UCL researchers. People from ethnic minority groups are even more likely to have previously diagnosed mental illnesses go unnoticed by medical staff, according to the findings from hospitals in England, published in PLOS Medicine .

The Government of India's use of nudge theory in the first three months of the pandemic helped to tackle the virus on numerous fronts, a new study suggests. The government urgently needed to buy time and... bring a deeply divided population together to fight a common struggle Ronita Bardhan India has reported nearly five million COVID-19 cases and well over 80,000 deaths (as of 17 September 2020), making the country one of the worst hit in the world.
Housing wealth matters for children’s mental health
Children growing up in families with expensive homes have fewer emotional and behavioural problems, finds new research led by the UCL Centre for Longitudinal Studies (CLS) based at the UCL Social Research Institute. The study, published today in Child Development, is one of the first to look at the links between family wealth and children's development.

Analysis: Post-traumatic stress disorder linked to increased risk of dementia
Dr Vasiliki Orgeta (UCL Psychiatry) shares new research which shows that PTSD is a risk factor for developing dementia. Dementia is one of the greatest global health challenges. As the world's population continues to age and to live longer, the number of people affected by dementia is expected to rise to 130 million by 2050.

Invaders, pirates, warriors - the history books taught us that Vikings were brutal predators who travelled by sea from Scandinavia to pillage and raid their way across Europe and beyond. The results change the perception of who a Viking actually was.
9/11 can teach us how to support those bereaved during COVID-19, researchers find
Researchers from a leading end-of-life charity have looked to 9/11 and other mass death events for approaches to support people bereaved through COVID-19. The team from the Marie Curie Palliative Care Research Centre in Cardiff and the University of Bristol, led by Dr Emily Harrop with senior authors Professor Anthony Byrne and Dr Lucy Selman, conducted a rapid review looking at which approaches were most effective in times of mass bereavement.

High levels of a growth factor increases risk for several cancers
A study of almost 400,000 British participants has identified a new link between raised levels of the growth factor IGF-1 and increased thyroid cancer risk and has confirmed associations with breast, prostate and colorectal cancer. This could lead to new preventative strategies, including diet and lifestyle interventions.

PTSD may double risk of dementia
People who have experienced post-traumatic stress disorder (PTSD) are up to twice as likely to develop dementia later in life, according to a new study by UCL researchers. The research, published in the British Journal of Psychiatry , is the first meta-analysis of global evidence on PTSD and dementia risk.

Slower growing broiler chickens are healthier and have more fun than conventional breeds of birds, new evidence from an independent commercial scale farm trial has shown. The study carried out by researchers from FAI Farms, the University of Bristol and The Norwegian University of Life Sciences, is published today [16 September], in Scientific Reports.
Mediterranean and tropical biodiversity most vulnerable to human pressures
Animals in tropical and Mediterranean areas are the most sensitive to climate change and land use pressures, finds a new study by UCL researchers. The findings, published today in Nature Ecology & Evolution , show how extinction risks are not evenly distributed worldwide, and suggest that large declines in tropical biodiversity are likely to occur imminently.
