The largest genetic study on anxiety disorders to date reveals new biological mechanisms behind anxiety. It can help to find new ways to develop more precise therapies. Around one in four people suffer from an anxiety disorder at some point in their lives. These include panic disorder with sudden, severe anxiety attacks, generalised anxiety disorder, in which sufferers worry about everyday things over a longer period of time that is difficult to control, and phobias of specific objects or situations.

Memories help animals survive by guiding them toward what to seek and what to avoid, such as remembering the smell of food or warning signs of danger. But in a constantly changing world, memories must also remain flexible. If a reward or threat no longer holds the same meaning, the brain needs ways to update what it has learned without completely forgetting the past.

Olympic skiers, bobsleighers and speed skaters all'have to master one critical moment: when to start. As athletes prepare for the upcoming Winter Olympics, that split second is in the spotlight because when everyone is fast, strong and skilled, a moment of hesitation can separate gold from silver. Research from Carnegie Mellon University helps explain why that split-second pause happens and how the brain controls it, offering insight not only into elite athletic performance, but also how people make everyday decisions when the outcome isn't clear.

Histological markings of an epileptic mouse irradiated with MRT; neurons are shown in blue, astrocytes in violet © Samalens et al, 2025, Epilepsia/Inserm Researchers at Inserm and the Université Grenoble Alpes (UGA) have discovered a new therapeutic approach to drug-resistant epilepsy. Fractional administration of X-ray microbeams induces a significant reduction in the occurrence of seizures in treated animals over a 2-month period: the first evidence in favor of a clinical application.

Researchers involving the University of Würzburg discover microscopic connection between correlated electron states and superconductivity. The study is published in Nature. How exactly unconventional superconductivity arises is one of the central questions of modern solid-state physics. A new study published in the scientific journal Nature provides crucial insights into this question.

Insulated joint systems are crucial for safe railway operation, but are susceptible to faults. The newly developed insulated joint is intended to extend service life and reduce maintenance and repair costs. Insulated joints are little known, but many railway lines could not be used without them. They divide the rail network into electrically separated sections and register when a train enters and leaves a section.

New study reveals urban ants more willing to accept low-quality food - a potential warning sign for urban ecosystems A new study published in the journal Urban Ecosystems has revealed that the common black garden ant ( Lasius niger ) behaves differently depending on whether it lives in a bustling city or the quiet countryside.

Ireland's approach to protecting vulnerable energy consumers could help other countries phase out harmful electricity disconnections without destabilising power markets, new research has found.

Salt stress stimulates restructuring programme inside plant cells The increasing content of sodium salts in the soil in many places is a problem for feeding the world's population: many plants thrive less well or not at all'on such soils.

For many people, cancer treatment still means surgery, chemotherapy, or radiotherapy. But today, for a growing number of patients, treatment can involve something very different: their own immune cells.

Groundwater is considered the largest reservoir of liquid freshwater on Earth and a habitat for complex microbial communities that drive essential biogeochemical cycles. Until now, the role of viruses that infect microorganisms in this hidden ecosystem was largely unknown.

A team led by UCL researchers with Great Ormond Street Hospital (GOSH) and Moorfields Eye Hospital, found B cells-alongside T cells-play a key role in arthritis-related eye disease (JIA uveitis), a condition that can cause long-term vision loss in children. The study, funded by the Medical Research Foundation, Moorfields Eye Charity, Arthritis UK and Fight for Sight challenges how the disease has been previously understood, and could open the door to new treatments that help protect children's sight.

A new international study highlights the major influence of the melting of the Antarctic ice cap in the past evolution of ocean circulation. The results show how this process has profoundly influenced the Earth's climate, and suggest that it could play a decisive role in the ocean's future capacity to absorb man-made carbon dioxide and excess heat linked to global warming.

An international collaboration involving researchers from the University of Innsbruck has developed a novel luminescent material that enables particularly robust and precise optical temperature sensing across an exceptionally broad temperature range. Optical luminescence thermometry has been gaining increasing importance, as it allows contactless temperature measurement even under extreme conditions.

New study, funded by Tommy's, finds care for pregnancy loss in the second trimester varies across the UK Care, including medication, bereavement support and interventions during subsequent pregnancies varies across the UK and Ireland 'A clear care pathway needs to be established' to ensure equitable appropriate care is provided across all'healthcare providers The care that women receive following a miscarriage during the second trimester of pregnancy varies according to where in the UK and Ireland the woman is treated, new research shows.

Documented for 200 years, the Iguanodontia group is expanding with the discovery of a brand-new species, the first known to bear spikes with properties never before observed in dinosaurs. Scientists from the CNRS 1 and their international partners have uncovered in China the fossilised skin of an exceptionally well preserved juvenile iguanodon.

Health A new type of brain implant may have implications for both brain research and future treatments of neurological diseases such as epilepsy.

UCalgary-led study reveals a genetic factor behind who may and may not benefit from opioids prescribed for pain Findings from international and cross-faculty collaboration provide insight on responses, including why some people may be at higher risk of dependency A University of Calgary-led international research team has identified a genetic factor that may explain why people respond so differently to opioid pain medications, and why some individuals face greater risk of side-effects including dependency.

Some Argentinian penguins are experiencing high levels of predation from pumas recolonising their historical territory. A new study involving Oxford researchers, published today in the Journal for Nature Conservation , has quantified the risk on long-term penguin population survival. Should we protect an emblematic species if it may come at the cost of another one - particularly in ecosystems that are still recovering from human impacts? This is the conservation dilemma facing Monte Leon National Park, on the Patagonian coast in Argentina.

Dr Darío Moreno Agostino (UCL Institute of Education) outlines his research into the mental health of baby boomers and generation X throughout their adulthoods, revealing persistent gender and socioeconomic inequalities and increased distress levels during the pandemic. It's been almost five years since the end of the COVID lockdowns.
