The replication success of scientific research is linked to research methods, citation impact and social media coverage - but not university prestige or citation numbers - according to a new study involving UCL researchers. Published in the journal Proceedings of the National Academy of Sciences  ( PNAS ), the study explores the ability of a validated text-based machine learning model to predict the likelihood of successful replication for more than 14,100 psychology research articles published since 2000 across six top-tier journals.

The short-term effects of vaporised cannabis do not differ between adolescents and adults, while cannabidiol (CBD) does not dampen the effects of the drug, finds a new study led by UCL and King's College London researchers. For the experimental study published in Addiction , the researchers measured how regular cannabis users of different ages responded to inhaling cannabis with differing levels of CBD.

Links between an area's health and employment figures are stronger when looking at self-rated health measures, compared with life expectancy or mortality indicators, finds a new study by UCL researchers. The research, published in BMC Public Health, sought to evaluate which health indicator is most closely linked to labour market outcomes, such as not being in paid work, working hours (i.e.

Researchers at UCL and the University of Cambridge have discovered a new type of ice that more closely resembles liquid water than any other known ices and that may rewrite our understanding of water and its many anomalies. The newly discovered ice is amorphous - that is, its molecules are in a disorganised form, not neatly ordered as they are in ordinary, crystalline ice.

Using talking therapies to effectively treat depression in adults over the age of 65 may be clinically linked with slightly reduced rates of future dementia diagnosis, finds a new analysis of health data led by UCL researchers. In this first-of-its-kind study, published in  Psychological Medicine  and funded by the Alzheimer's Society, researchers assessed whether psychological therapies, such as Cognitive Behavioural Therapy (CBT), used to treat depression could play a role in dementia risk reduction.

People aged 50 and over who live in rural England do better in memory tests than counterparts who live in English towns and cities, according to a new study led by UCL researchers. The study, published in the Journal of Gerontology: Social Sciences, looked at the results of memory tests taken by two nationally representative population samples, whose participants were aged 50 and over, in England and China.

Loyalty card data on over-the-counter medicine purchases could help spot ovarian cancer cases earlier, finds a new study involving UCL researchers. The first-of-its kind study, published in JMIR Public Health and Surveillance , found that pain and indigestion medication purchases were higher in women who were subsequently diagnosed with ovarian cancer, compared to women who did not have ovarian cancer.

A survey of over 2,000 British adults, conducted in part by a UCL researcher, finds that trust in genetics is high, and went up significantly during the pandemic. The survey findings feature in a report published online by the Genetics Society and have also fed into a peer-reviewed research paper, published in PLOS Biology , which reports that people with more extreme attitudes towards science have the most self-confidence in their understanding of science.

Core symptoms of anxiety and depression were more common among younger generations compared to older age groups during the COVID-19 outbreak - with the gap between young and old widening further during the pandemic, according to a new study by UCL and King's College London. Published today in Psychological Medicine, the study explores data from 26,772 people living in the UK across five different birth cohort studies - following those born in 1946, 1958, 1970, 1989-90 and 2000-02.

Half of the world's languages are endangered and more than a thousand are expected to be lost in coming decades. A team at UCL is using animation software to preserve these languages in an entirely new way. It's estimated that there are over 7,000 documented languages spoken across the world. Yet around half of these languages are endangered.

COVID-19 is associated with higher risks of cardiovascular disease and death in the shortand long-term, according to a study in nearly 160,000 unvaccinated participants co-led by a UCL researcher. The study, published today in Cardiovascular Research , a journal of the European Society of Cardiology, investigated outcomes in a group of adults mostly aged in their 60s.

A newly-published hypothesis, led by a UCL researcher, suggests a momentary leap in a single species on a single day millions of years ago might ultimately have led to the arrival of mammals - and therefore humans. Published in the Journal of Cell Science , Professor John Martin (UCL Division of Medicine) thinks a single genetic molecular event (inheritable epigenetic change) in an egg-laying animal may have resulted in the first formation of blood platelets, approximately 220 million years ago.

A multi-disciplinary team of researchers, involving several UCL scientists, has developed a way to monitor the progression of movement disorders using motion capture technology and AI.

A free new digital tool has been launched by Alzheimer's Research UK, supported by evidence from UCL researchers, to help people keep their brain healthy and reduce their dementia risk. Only 2% of the public are doing everything they can to keep their brains healthy, according to new figures released by the charity.

A universal criteria for diagnosing the blinding eye condition, optic neuritis, has been developed by a UCL-led team of researchers. Optic neuritis is inflammation in the optic nerve and is a common cause of sudden and acute vision loss, affecting around 6 in 100,000 people. It may occur at any age with vision loss typically occurring over several hours or a few days , from onset Sometimes optic neuritis is caused by multiple sclerosis (MS), but it can also be triggered by many other conditions.

Experiencing abuse or neglect as a child can cause multiple mental health problems, finds a new study led by UCL researchers. The research, published in the American Journal of Psychiatry , seeks to examine the causal effects of childhood maltreatment on mental health by accounting for other genetic and environmental risk factors, such as a family history of mental illness and socioeconomic disadvantage.

A large-scale Phase 3 clinical trial to establish ambroxol's potential to slow the progression of Parkinson's disease, will start in early 2023. Ambroxol is a drug which is currently used to treat respiratory conditions. It promotes the clearance of mucus, eases coughing and has anti-inflammatory properties.

Women's reproductive needs should be considered holistically by considering pregnancy prevention and pregnancy preparation at the same time, finds a new study led by UCL researchers. The research, published in The Lancet Public Health , brought together a variety of different types of evidence - including previous studies, new data on women's preferences, and case studies of existing practice across the globe - to develop a model, which could be used to help design services in a way that better meets the needs of women and their partners.

The skulls of early dinosaurs are helping scientists understand how some of the earliest herbivores may have evolved different ways of eating plants, reports a new study involving UCL. Most dinosaurs were plant eaters, although they are all descended from a carnivorous ancestor. Much is already known about how different dinosaurs consumed their food, but relatively little is understood about how they evolved their preferred eating styles.

Professor Ruth Mace and PhD candidate Yuan Chen (both UCL Anthropology) share their anthropological study in The Conversation examining the gender division of work and how workloads are changing across different societies. For most people around the world, physical work takes up a great amount of time and energy every day.
