Researchers used a deep learning AI model to uncover the first imaging-based biomarker of chronic stress by measuring adrenal gland volume on routine CT scans. This new metric, the Adrenal Volume Index, correlates strongly with cortisol levels, ...

A decade-long study of older women found that tea drinkers had slightly stronger bones, while moderate coffee drinking caused no harm. Heavy coffee intake--over five cups a day--was linked to lower bone density, especially in women who consumed more ...

Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from harm. These ...

A new analysis suggests that people with type 2 diabetes who use GLP-1 medications like Ozempic, Trulicity or Victoza may be less likely to develop epilepsy than those taking DPP-4 inhibitors. Semaglutide showed the strongest connection to lowered .. ...

Researchers discovered that children who went back to school during COVID experienced far fewer mental health diagnoses than those who stayed remote. Anxiety, depression, and ADHD all declined as in-person learning resumed. Healthcare spending tied . ...

Researchers used AI to pinpoint a little-known monkeypox protein that provokes strong protective antibodies. When the team tested this protein as a vaccine ingredient in mice, it produced a potent immune response. The discovery could lead to simpler, ...

Scientists discovered that certain gene changes allow cells to function even when frataxin, the protein lost in Friedreich's ataxia, is missing. Experiments in worms, human cells, and mice revealed that lowering a gene called FDX2 helps restore vital ...

Emerging evidence hints that daily multivitamins might quietly help certain older adults keep their blood pressure in check--especially those with poorer diets and normal readings at the start. While the overall results showed no broad benefit, ...

A sweeping review of more than 2,500 studies reveals that despite booming public enthusiasm, cannabis has strong scientific support for only a few medical uses, leaving most popular claims--like relief for chronic pain, anxiety, and insomnia--on ...

Scientists have uncovered a surprising link between dark chocolate and slower aging. A natural cocoa compound called theobromine was found in higher levels among people who appeared biologically younger than their real age.
