Researchers found that social behavior begins in the brain before it becomes visible as movement. In zebrafish, a coordinated pattern of activity spread across the brain several seconds before the animals approached another fish. A higher brain ...

A surprising new study suggests that when it comes to pancreatic cancer, the kind of fat you eat may matter more than how much. Researchers found that oleic acid--the main fat in olive oil and several other common foods--sped up tumor growth in mice ...

A Salk Institute study found that a simple dietary amino acid, methionine, dramatically improved survival in mice facing severe infections and inflammatory conditions. Rather than directly targeting the immune system, methionine boosted kidney ...

A promising new study suggests rheumatoid arthritis may not be as inevitable as once thought for people at high risk. Researchers found that just one year of treatment with the immune-targeting drug abatacept delayed the onset of rheumatoid arthritis ...

A long-overlooked organ may hold surprising clues to healthy aging and cancer survival. Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses--a small immune ...

Scientists at Scripps Research have uncovered a molecular "switch" that appears to fuel the damaging brain inflammation seen in Alzheimer's disease. They found that a protein called STING becomes chemically altered in a way that keeps the brain's ...

Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged mice, and then dropped again in very old mice. The .. ...

Losing weight may involve rewiring the gut and the brain at the same time. In a study of obese adults, an intermittent fasting-style diet led to significant weight loss, healthier metabolic markers, and notable shifts in gut bacteria. Brain scans ...

A new study suggests fish oil may help reduce insulin resistance even in people who aren't obese. In diabetic rats, omega-3 supplementation improved blood sugar levels, cholesterol, and inflammation by shifting immune cells into a more anti ...

A new study suggests melatonin supplements may help night shift workers boost their body's DNA repair processes, potentially offsetting some of the damage linked to working overnight. The findings are early but raise the possibility of a simple ...
