Boston researchers linked nighttime light exposure to greater stress-related brain activity and inflamed arteries, signaling a higher risk of heart disease. The study suggests that artificial light at night disrupts normal stress responses, leading . ...

Duke-NUS scientists unveiled BrainSTEM, a revolutionary single-cell map that captures the full cellular diversity of the developing human brain. The project's focus on dopamine neurons provides crucial insight for Parkinson's treatment. Their ...

Scientists uncovered how the amino acid leucine enhances mitochondrial efficiency by preserving crucial proteins that drive energy production. By downregulating the protein SEL1L, leucine prevents unnecessary degradation and strengthens the cell's .. ...

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that block infection. Understanding this mechanism could ...

A team of scientists has developed a highly accurate blood test for Chronic Fatigue Syndrome. The test reads tiny DNA patterns that reveal the biological signature of the illness. For millions who've faced doubt and misdiagnosis, it's a breakthrough ...

Disrupted sleep patterns in Alzheimer's disease may be more than a symptom--they could be a driving force. Researchers at Washington University found that the brain's circadian rhythms are thrown off in key cell types, changing when hundreds of genes ...

Scientists have discovered that a "longevity gene" found in people who live beyond 100 can reverse heart aging in models of Progeria, a devastating disease that causes children to age rapidly. By introducing this supercentenarian gene into Progeria . ...

Cognitive struggles are climbing across the U.S., especially among young and economically disadvantaged adults. Rates of self-reported cognitive disability nearly doubled in people under 40 between 2013 and 2023. Researchers suspect social and ...

Researchers discovered that altering the body's natural rhythm can help protect the brain from Alzheimer's damage. By turning off a circadian protein in mice, they raised NAD+ levels and reduced harmful tau buildup. The findings suggest that ...

New research from Australia overturns the old idea that exercise "uses up" heartbeats. It shows that fitter people actually use fewer total heartbeats each day thanks to their lower resting heart rates, even when accounting for workouts. Athletes' .. ...
