Air pollution is a global health concern, with over 90% of the world's population breathing air that exceeds World Health Organization safety standards.

Ingredients of our daily diet - including caffeine - can influence the resistance of bacteria to antibiotics. This has been shown in a new study by a team of researchers at the Universities of Tübingen and Würzburg led by Professor Ana Rita Brochado.

People with any type of substance use disorder (SUD) stand a 24% higher risk of having an unplanned hospital readmission within 30 days of a previous discharge compared with those without the disorder, new UCLA-led research finds.

Respiratory syncytial virus (RSV) is a well-known cause of infections in children, but it's understudied in older individuals.

In a major stride toward tackling aggressive breast cancer, researchers from The Hebrew University of Jerusalem have developed druglike molecules that degrade a previously "undruggable" cancer-driving protein.

Promoting pyroptosis-an inflammatory form of programmed cell death-has become a promising treatment strategy for cancer.

This study reveals how probiotic bacteria directly influence brain cell function, highlighting gut-brain communication and potential therapeutic applications.

New genetic research reveals polygenic scores can predict obesity risk, offering early prevention insights while raising ethical healthcare access concerns.

Colon cancer remains a major global health concern, ranking third among the most diagnosed cancers and leading causes of cancer-related death worldwide.

Researchers led by Gen Kurosawa at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan have used theoretical physics to discover how our biological clock maintains a consistent 24-hour cycle-even as temperatures change.

In a wholly new approach to cancer treatment, Northwestern University biomedical engineers have doubled the effectiveness of chemotherapy in animal experiments.

The annual UK cost of the mental health disorder PTSD is likely to top £40 billion, but the figures are based on 2020-1 prevalence rates-the most recently available-and don't include many indirect costs, such as family support services, finds a cost analysis published in the open access journal BMJ Open.

Landmark trials have shown that GLP-1 receptor agonists, originally developed for diabetes and weight loss, also provide significant benefits for cardiovascular, kidney, liver, joint, and sleep-related diseases. These effects extend beyond weight loss, suggesting anti-inflammatory mechanisms with broad potential for managing chronic diseases.

GLP-1 receptor agonists, a class of drug used to treat type 2 diabetes, likely trump the widely prescribed metformin for curbing dementia risk in people with the condition, finds the largest study of its kind, published in the open access journal BMJ Open Diabetes Research & Care.

The UC Davis Department of Ophthalmology has received a five-year, $3.6 million grant from the National Eye Institute to explore a new way to treat vision loss using gene therapy.

Using gene therapy to treat hereditary deafness is safe and effective in both children and adults, according to new findings from a multicenter clinical trial.

Metformin is a widely used first-line therapy for type 2 diabetes, and studies increasingly point to its protective effects on the kidney.

A new review explains how fad diets and unregulated supplements promoted online can cause serious skin, hair, and nail problems, often before other symptoms appear. Clinicians are urged to recognize these risks and address health misinformation in the digital age.

Researchers found that optimistic individuals share similar patterns of brain activity when imagining future events, especially distinguishing positive from negative scenarios. This neural convergence may help explain why optimists experience greater emotional clarity and social connection.

Researchers identified a combination of two existing cancer drugs, letrozole and irinotecan, that reversed Alzheimer’s disease-related changes in brain cell networks and improved memory in mouse models. The study supports a multi-cell-type, network-correcting strategy as a promising path for future Alzheimer’s treatments.
