Scientists say this common sweetener may be quietly rewiring your metabolism
Researchers say fructose is not just "empty calories" - it may actively push the body toward fat storage and metabolic disease. A new review found that fructose affects the body differently from glucose, disrupting normal energy regulation and promoting processes linked to obesity, insulin resistanc...
Scientists say 8,500 steps a day could stop weight from creeping back
A new international analysis suggests there may be a surprisingly simple secret to keeping weight off after dieting: walking about 8,500 steps a day. Researchers found that people who boosted their daily steps to around that level during a weight-loss program - and kept it up afterward - were far mo...
Ozempic delivers major weight loss in adults over 65, study finds
A major new analysis suggests semaglutide (Ozempic, Wegovy) works remarkably well in adults over 65, helping many lose substantial amounts of weight while improving heart and metabolic health. Participants taking the drug lost over 15% of their body weight on average - far more than those receiving ...
This 800-year-old Chinese exercise helps lower blood pressure naturally
An ancient Chinese exercise routine may be just as powerful as a daily brisk walk for lowering blood pressure - without equipment, gyms, or intense workouts. In a major clinical trial, adults with stage 1 hypertension who practiced baduanjin, a gentle mind-body exercise combining slow movements, bre...
Ultra-processed foods linked to higher risk of heart disease and early death
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, obesity, diabetes, high blood pressure, and even car...
Scientists successfully transfer longevity gene and extend lifespan
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. The special gene boosts production of a substance called high molecular wei...
Scientists discover the brain's hidden "stop scratching" switch
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. In experiments involving chronic itch simila...
Scientists reversed liver aging with young gut bacteria in stunning study
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. Older mice that received their own preserved youthful microbiome showed less inflammation, reduced DNA damage, and no signs of liver cancer...
Black licorice compound shows promise against inflammatory bowel disease
Researchers have developed a stem cell-based model of the human intestine that may transform how new IBD treatments are discovered. After testing thousands of compounds, they identified glycyrrhizin - a natural substance found in black licorice - as a promising anti-inflammatory candidate. In both l...
Scientists say this simple music trick can boost workout endurance by 20%
A new study shows that listening to your own favorite workout music can dramatically boost endurance. Cyclists exercising with self-selected songs lasted nearly 20% longer than when riding in silence, yet they didn't feel more exhausted at the end. Researchers say music may help people stay in the "...
Scientists found the "holy grail" gene that could one day help humans regrow limbs
Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful "SP genes" involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. ...
New obesity discovery rewrites decades of fat science
Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease. A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells-...
A common constipation drug shows surprising power to protect kidneys
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. In a clinical trial involving 150 patients, researchers found that lubiprostone, a medication normally used to treat constipation, helpe...
Scientists discover a new way to prevent gum disease without killing good bacteria
Scientists have uncovered a surprising way to influence the bacteria living in our mouths - not by killing them, but by interrupting how they "talk" to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those signals, they were able t...
What scientists found inside coral reefs could change the future of medicine
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. These microbes produce a stunning variety of chemical compounds with potential u...
Doctors warn this popular vitamin may quietly disrupt cancer care
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. While biotin is often marketed for stronger hair and nails, there's little evidence it actually helps cancer-related hair loss-and it can dan...
Scientists find natural compounds that hit COVID-19 from every angle
A little-known tree from Brazil's Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts-blocking the virus from entering cells, disrupting its replication, a...
Eating eggs could cut Alzheimer's risk by 27%
Eating eggs might do more than just start your day-it could help protect your brain. Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer's disease, with daily or near-daily consumption linked to up to a 27% reduction. Even modest ...
New "Trojan horse" obesity drug supercharges weight loss in early tests
Researchers have created a next-generation obesity drug that works like a "Trojan horse," using GLP-1/GIP signals to slip a powerful metabolic enhancer directly into target cells. In mice, it outperformed existing treatments-curbing appetite, increasing weight loss, and improving blood sugar levels....
Scientists discover why Ozempic works better for some people
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 year-long study in Japan found that people who tend to eat because tempting food looks or smells irresistible were much more likely to lose weight...
