Getting enough vitamin B12 to meet current health guidelines may not actually be enough to protect the aging brain. Researchers at UC San Francisco found that older adults with “normal” but lower levels of active B12 showed signs of slower thinking,…

A surprisingly simple walking tweak may offer new hope for millions living with knee osteoarthritis. In a year-long clinical trial, researchers found that slightly changing the angle of a person’s foot while walking reduced knee pain as effectively as…

A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite…

A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection.…

A daily multivitamin may help slow biological aging, according to researchers studying older adults in a large clinical trial. After two years, participants taking multivitamins showed slower aging in several DNA-based “epigenetic clocks,” with the effect…

Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests.…

Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly…

Scientists at McGill University have uncovered a hidden molecular “switch” that turns on a powerful calorie-burning system in brown fat — the body’s heat-generating fat linked to metabolism and weight control.…

Staying strong may be one of the biggest secrets to living longer — especially for older women. A major study of more than 5,000 women found that simple signs of muscle strength, like a firm hand grip or the ability to quickly stand up from a chair, were…

Ultra-processed foods may be doing far more damage than many people realize. A major new European cardiology report warns that people who eat the most ultra-processed foods face significantly higher risks of heart disease, irregular heart rhythms,…

Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice.…

A common constipation drug may have unexpectedly unlocked a new way to slow chronic kidney disease — a condition that affects millions and often leads to dialysis.…

Some people taking Ozempic-like diabetes drugs may be getting dramatically better results for a surprising reason: why they overeat in the first place.…

A short burst of immunotherapy before surgery is delivering surprisingly powerful results for a specific type of colorectal cancer. Patients in a UK-led trial who received just nine weeks of pembrolizumab prior to surgery have remained cancer-free nearly…

A major 10-year clinical trial is turning one of the world’s most common knee surgeries on its head. Researchers found that trimming a damaged meniscus—a procedure long believed to relieve pain—offers no real benefit over placebo surgery.…

Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing.…

A chaotic sleep schedule in your 40s might be quietly setting the stage for heart trouble later. Researchers tracking thousands of people for over a decade found that those with highly inconsistent bedtimes—especially when they slept less than eight…

GLP-1 weight-loss drugs like Ozempic and Wegovy are often celebrated as game-changing solutions—but new research reveals a surprising social twist.…

A new study suggests depression may soon be detectable through a simple blood test—by tracking how certain immune cells age. Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and cognitive…

Drugs designed to clear amyloid beta from the brain—once seen as a promising path to slowing Alzheimer’s—may not actually help patients in any meaningful way, according to a major review of over 20,000 participants.…
