Psychedelics can quiet the brain's visual input system, pushing it to replace missing details with vivid fragments from memory. Scientists found that slow, rhythmic brain waves help shift perception away from the outside world and toward internal ...

A massive review of 23 randomized trials found that statins do not cause the vast majority of side effects listed on their labels. Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking ...

Scientists at Michigan State University have uncovered the molecular "switch" that powers sperm for their final, high-speed dash toward an egg. By tracking how sperm use glucose as fuel, the team discovered how dormant cells suddenly flip into ...

Couples who intentionally slow down and soak in their happy moments together may be building a powerful shield for their relationship. Researchers at the University of Illinois found that partners who regularly savor shared experiences--whether ...

Scientists are launching an ambitious global effort to map the "human exposome" -- the lifelong mix of environmental and chemical exposures that drive most diseases. Backed by new partnerships with governments, UNESCO, and international science ...

A global study has uncovered a mysterious group of gut bacteria that shows up again and again in healthy people. Known as CAG-170, these microbes were found at lower levels in people with a range of chronic diseases. Genetic clues suggest they help . ...

A new study suggests that generosity may be more than a moral lesson--it could be shaped by how different parts of the brain work together. By gently stimulating two brain regions and syncing their activity, researchers found that people became more ...

Fish oil's cancer-fighting reputation may hinge on a little-known gene. Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in ...

Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes--located . ...

Microplastics and nanoplastics are now found everywhere on Earth, from ocean depths to agricultural soils and even inside the human body. Yet scientists still struggle to understand what these particles actually do once they enter living organisms. A ...
