How easily birds can fly between suitable areas strongly determines whether a particular species can survive habitat fragmentation. A new study shows why tropical birds are likely to be more vulnerable to forest fragmentation, and suggests conservation policies need to take into account the role of climate in determining the ability of animals to move across fragmented landscapes.
Study of 2,500-year-old latrines from the biblical Kingdom of Judah shows the ancient faeces within contain Giardia - a parasite that can cause dysentery. Toilets with cesspits from this time are relatively rare and were usually made only for the elite Piers Mitchell A new analysis of ancient faeces taken from two Jerusalem latrines dating back to the biblical Kingdom of Judah has uncovered traces of a single-celled microorganism Giardia duodenalis - a common cause of debilitating diarrhoea in humans.
Researchers from UCL, the UK Dementia Research Institute, Imperial College London and Newcastle University, are involved in a major new collaboration to develop a technology that could help identify people at risk of developing dementia by analysing their sleep patterns. Using a Sleep Analyzer tracking mat produced by technology company, Withings, the researchers created The Dementia Sleep Index - by comparing sleep patterns of people living with dementia to data that equates to 3.7million nights of sleep in the general population.
Scientists propose revolution in complex systems modelling with quantum technologies
Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly reduced memory. Complex systems play a vital role in our daily lives, whether that be predicting traffic patterns, weather forecasts, or understanding financial markets.

Five subtypes of heart failure that could potentially be used to predict future risk for individual patients have been identified in a new study led by UCL researchers. Heart failure is an umbrella term for when the heart is unable to pump blood around the body properly. Current ways of classifying heart failure do not accurately predict how the disease is likely to progress.
A cleft lip or palate arises from the combined effects of genes and inflammatory risk factors experienced during pregnancy, such as smoking or infections, finds a new study led by UCL researchers. The study, published in Nature Communications , has revealed for the first time how genetic and environmental factors come together to form a cleft lip or palate in a developing foetus.
Hearing loss unlikely to be common symptom of Covid, say scientists
Hearing loss is unlikely to be a common symptom of Covid-19, a study led by The University of Manchester and the National Institute for Health and Care Research (NIHR) Manchester Biomedical Research Centre (BRC) scientists have shown. The virus has been blamed for a range of health problems including hearing loss and other auditory disorders.

Anticoagulation treatment after an ischemic stroke should be started earlier
An international clinical trial, which involved experts from Glasgow, has concluded that anticoagulation treatment could be safely started earlier than current recommended guidelines in patients following ischemic stroke with atrial fibrillation. The study - published in the New England Journal of Medicine and led by the led by the Stroke Center, Inselspital, University Hospital Bern, and the University of Bern - found the chances of suffering a recurrent event with earlier treatment were likely to be lower compared to a later start, without an increase in risk of complications.

The biology underpinning a rare genetic mutation that allows its carrier to live virtually pain-free, heal more rapidly and experience reduced anxiety and fear, has been uncovered by new research from UCL. The study, published in Brain , follows up the teams' discovery in 2019 of the FAAH-OUT gene and the rare mutations that cause patient, Jo Cameron, to feel virtually no pain and never feel anxious or afraid.
Researchers have found a stark gender imbalance after carrying out the largest-ever study of video game dialogue, published today. The research, published in the journal Royal Society Open Science , analysed more than 13,000 video-game characters and found that men speak twice as much as women. The study, led by Dr Stephanie Rennick at the University of Glasgow and Dr Seán G. Roberts at Cardiff University, performed the first large-scale test of gender imbalance in the dialogue of 50 role-playing video games (RPGs).
Research led by UCL, in partnership with the MRC Laboratory of Molecular Biology (MRC LMB) and AstraZeneca, has identified a new compound that can stimulate nerve regeneration after injury, as well as protect cardiac tissue from the sort of damage seen in heart attack. The study, published in Nature , identified a chemical compound, named '1938', that activates the PI3K signalling pathway, and is involved in cell growth.
University of Glasgow researchers prepare for next gravitational wave observing run
Researchers from the University of Glasgow's School of Physics & Astronomy are preparing for the next observing run of the international LIGO-Virgo-KAGRA (LVK) network of gravitational-wave detectors. The LVK collaboration consists of scientists across the globe who use a network of observatories-LIGO in the United States, Virgo in Europe, and KAGRA in Japan-to search for gravitational waves, or ripples in space-time, generated by colliding black holes and other extreme cosmic events.

Gender trumps politics in determining people’s ability to read others’ minds
Psychologists surveyed over 4,000 people to test social ability to analyse what factors determine how well you understand and get on with others. Political parties regularly claim to have their finger on the pulse and be able to read the public mood. Yet a new study challenges the idea that being political makes you good at understanding others: it shows gender, not politics, is a far more important factor in determining people's social skills.

Credit holidays, which allowed borrowers to postpone their credit repayments during the pandemic, helped improve the mental health of those who used them finds Dr Jacques Wels (UCL MRC Unit for Lifelong Health & Ageing), writing in The Conversation. Like other countries, the UK implemented a number of initiatives to mitigate the effects of the COVID-19 pandemic on people's economic circumstances.
What’s behind burnout and exhaustion in nursing staff?
A research survey of almost nine-hundred nursing staff has found that long hours combined with poor staffing and little choice in working patterns is likely to be behind nurses burning out and becoming exhausted at work. Working 12-hour shifts in hospitals is quite common and in previous research it has been found that nursing staff that regularly work long shifts can burn out, and in some cases leave the profession or become ill.

Ageing may contribute to tendon injuries
New research from the Royal Veterinary College (RVC) has identified the different cell populations in horses' tendons and established which cells are most affected by ageing. These findings will help develop a better understanding of why older horses (and humans) are more prone to tendon injuries and inform future treatments.

Importance of neuroscientific evidence for rape trials
The law should take into consideration neuroscientific evidence that suggests fear and threat can cause victims to become 'frozen' in cases of rape or sexual assault, argue UCL experts. In a comment article, published in Nature Human Behaviour, Professor Patrick Haggard and former UCL undergraduate, Ebani Dhawan, state that victims of sexual assault are often blamed for not fighting or fleeing their attackers.
