Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan report a link between deep sleep and cerebrospinal fluid, the clear liquid that surrounds and supports the brain and spinal cord.

As cancer survivorship rises, many people living with or beyond cancer face lasting physical and emotional challenges – particularly anxiety and depression, which affect about 30% of this population. Emotional distress is often unspoken, leading to fear, despair, and diminished quality of life.

Researchers at Tufts University School of Medicine and Tufts Graduate School of Biomedical Sciences have found a surprising connection between a fungus associated with alcohol use disorder and the brain's dopamine reward pathway.

The health of the thymus - a key part of the body's immune system - is associated with cancer patients' outcomes to immune checkpoint inhibitor treatment, according to a ground-breaking international study reported at ESMO 2025.

A research team from the Medical University of Vienna and the Medical University of Graz has discovered a previously unknown genetic cause of hereditary optic atrophy, a degenerative disease of the optic nerve associated with gradual loss of vision.

A study published in Environment International concludes that air pollution during pregnancy is associated with slower brain maturation in newborns.

A research team at the Seville Biomedical Institute (IBis) has identified a new molecular mechanism that explains the high sensitivity of Ewing sarcoma (an aggressive bone cancer that mainly affects children and adolescents) to certain chemotherapy drugs, such as irinotecan.

Imposter participants threaten the integrity of health research and, by extension, the policies and clinical decisions built on it, warn experts in The BMJ today.

The prevalence of obesity in the United States could rise sharply under a new definition of obesity released earlier this year by the Lancet Diabetes and Endocrinology Commission.

A new study, led by experts at the University of Nottingham, has found that combining certain types of dietary supplements is more effective than single prebiotics or omega-3 in supporting immune and metabolic health, which could lower the risk of conditions linked to chronic inflammation.

Community sporting clubs must rethink how they engage parents if they want to stop the slide in young people dropping out of sport, according to new Flinders University research.

A team from Huntsman Cancer Institute at the University of Utah (the U) has found that triple-negative breast cancer is fueled by lipids and that these fatty acids are a key feature of obesity that promote tumor growth.

Researchers at the Medical University of Vienna have taken a closer look at a previously largely unknown component of the immune system: the protein molecule TRAT1 (T Cell Receptor Associated Transmembrane Adaptor 1) plays a central role in how so-called T helper cells (a specialised subgroup of immune cells) distinguish between attack and self-control - an important mechanism for restraining inflammation and preventing autoimmune diseases. The findings have recently been published in the journal Cell Communication and Signaling.

A new clinical trial co-led by researchers at FutureNeuro and RCSI University of Medicine and Health Sciences is investigating how advanced brain monitoring could improve the diagnosis and management of epilepsy.

One in four hepatologists in the United States screened positive for unhealthy alcohol use in a survey study conducted by UCLA.

The most reliable predictor of an ex-smoker's relapse isn't strong urges to smoke or low confidence in the ability to stay off tobacco – it's weariness with the efforts to remain a non-smoker, according to a new study published today in Addiction.

A new breakthrough in a rare genetic disease which causes children to age rapidly has been discovered using 'longevity genes' found in people who live exceptionally long lives - over 100 years old.

New research from the University of Delaware finds that LGBTQ+ adolescents in Delaware face strikingly higher rates of mental health challenges and substance use compared to their peers.

Will it be possible to treat severe kidney inflammation with fewer drugs in the future? A new study by the University Hospital Bonn (UKB), the University of Bonn, and the University of Hamburg gives cause for hope.
