Emerging evidence links tire pollution to Alzheimer's risk

A chemical called 6PPD-quinone (6PPD-Q), which forms when shaved-off tire particles come into contact with ozone, might interfere with the inner workings of brain cells, leading to Alzheimer's disease. Zhang and Zhang's new paper in the journal Open Medicine, "6PPD‑Quinone Exposu

AI tool can identify biological profiles associated with thrombosis risk

Two people may be the same age and have similar family histories or risk factors, yet only one of them may develop thrombosis. To better understand why this occurs, researchers from the Complex Disease Genomics Unit at the Sant Pau Research Institute (IR Sant Pau) and the Biomedi

Just one exposure to cocaine alters mouse brain cells for 2 weeks, research reveals

Researchers studying the impact of cocaine in mice have found that just one exposure to the drug can create changes in brain cells that persist for at least two weeks. Their findings were presented at the Federation of European Neuroscience Societies (FENS) Forum 2026.

Mutations let JC polyomavirus evade antibodies, offering clues for vaccines and treatments

In people with severely compromised immune systems, JC polyomavirus can trigger an untreatable, often fatal brain disease. An international research team has identified how virus mutations can strategically interfere with how human antibodies recognize the virus, allowing it to e

Identifying the healing powers of sacred moments in health care

In health care, it is often the smallest moments that carry the greatest meaning—a quiet conversation with a patient, a shared reflection with colleagues, or a hand held in silence. These brief yet powerful connections, known as sacred moments, are the focus of new research explo

Scientists uncover two neuronal circuits orchestrating muscle autophagy

Autophagy is the process by which cells remove damaged proteins, recycle worn-out organelles (e.g., mitochondria), clear cellular waste and provide nutrients during stress. Autophagy is essential for muscles because they are constantly under mechanical stress. If autophagy is too

How skimping on sleep leads to weight gain

People who shortened their sleep by around 80 minutes a night for six weeks gained weight—1 pound on average—and were more sedentary, researchers at Columbia University Vagelos College of Physicians and Surgeons found.
