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 ...

A low-fat vegan diet--without cutting calories or carbs--may help people with type 1 diabetes significantly reduce how much insulin they need, and how much they spend on it. In a new analysis published in BMC Nutrition, participants following the ...

A robotic arm that moves too quickly can feel creepy. One that moves too slowly feels awkward and unhelpful. In a VR study, researchers found that AI-powered prosthetic arms were best accepted when they moved at a natural, human-like speed--about one ...

A protein called HIF1 may be the missing link behind painful tendon injuries like jumper's knee and tennis elbow. Researchers showed that high levels of HIF1 actually cause harmful changes that make tendons brittle and prone to pain. In experiments, ...

A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle ...

Swapping just an hour of TV a day for something more active could significantly lower the risk of developing major depression--especially in middle age. A large Dutch study tracking more than 65,000 adults over four years found that replacing 60 ...

A six-week study from the University of Nottingham suggests that pairing fermented kefir with a diverse prebiotic fiber mix may deliver a powerful anti-inflammatory boost. This "synbiotic" combination outperformed omega-3 supplements and fiber alone, ...

A simple brain-training program that sharpens how quickly older adults process visual information may have a surprisingly powerful long-term payoff. In a major 20-year study of adults 65 and older, those who completed five to six weeks of adaptive . ...
