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…

Vitamin B12 has long been seen as a health hero, helping the body make red blood cells, repair DNA, and keep nerves functioning properly. But scientists are discovering that the story may be more complicated than simply “more is better.” While too little…

A newly identified protein called GPNMB may play a major role in helping Parkinson’s disease spread through the brain. Researchers discovered that immune cells release the protein in response to damaged neurons, creating a vicious cycle that speeds up…

A casual conversation between graduate students helped spark a breakthrough in aging research at Mayo Clinic. Researchers discovered that tiny synthetic DNA molecules called aptamers can selectively attach to senescent “zombie cells,” which are linked to…

A groundbreaking Swedish study that tracked people for nearly 50 years has revealed when the body’s physical decline quietly begins. Researchers found that fitness, strength, and muscle endurance start slipping around age 35, with the decline accelerating…

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…

Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a…

As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells.…

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.…

Scientists at the University of Rochester pulled off a remarkable experiment: they transferred a longevity-related gene from the famously long-lived naked mole rat into mice, and the mice ended up healthier and lived longer.…

Scientists have uncovered a hidden “stop-scratching” signal in the nervous system that tells your brain when enough scratching is enough. The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief.…

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.…

Many cancer patients turn to biotin supplements hoping to restore hair lost during treatment, but experts warn the popular vitamin may do more harm than good.…

Beneath the beauty of coral reefs lies a hidden universe of microbes unlike anything scientists expected. Each coral species supports its own specialized microbial partners, many of which have never been studied before.…

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 new study suggests a surprisingly simple compound could help fight Alzheimer’s disease. Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of the…

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…
