This new drug could break cancer’s resistance to treatment
A new experimental drug called CS18 may help break through cancer drug resistance by disabling several of the defenses tumors use to survive treatment. It strengthened existing therapies, restored drug...
View ArticleThis emerging treatment could help people avoid knee replacement surgery
A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood...
View ArticleCoffee doesn’t have to keep you awake to disrupt your sleep
Caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours, with EEG recordings revealing fewer of the slow brain waves associated with deep sleep....
View ArticleStem cells reverse stroke damage and restore movement in mice
Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the...
View ArticleStopping Ozempic may raise heart attack and stroke risk
A large study suggests the cardiovascular benefits of GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound can disappear surprisingly quickly when treatment stops. After two years off the...
View ArticleBrain scans reveal a possible cause of long COVID fatigue and brain fog
Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties....
View ArticleScientists create a needle-thin brain implant that can do three jobs at once
A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give scientists...
View ArticleChronic stress may be quietly reshaping your heart
Chronic inflammation tied to stress, lifestyle, mental health, and socioeconomic conditions may silently change the heart for years before any symptoms appear. People with the highest inflammation...
View ArticleStanford scientists discover the human brain may actually be two separate organs
Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also...
View Article8 common food additives linked to high blood pressure and heart disease
Common preservatives hiding in processed foods may carry unexpected heart risks, with heavy consumption linked to substantially higher rates of high blood pressure and cardiovascular disease....
View ArticleMillions take calcium and vitamin D for bone health. A major review finds...
A sweeping review of more than 153,000 adults found that calcium and vitamin D supplements, alone or together, do little to prevent fractures or falls in most older people. Researchers say the findings...
View ArticleA deadly ebola relative is surging after years in the shadows
A growing Bundibugyo virus outbreak is showing how a little-known relative of Ebola can become a major threat when diagnosis and treatment options are limited. Experts warn that preparing only for...
View ArticleAncient DNA reveals how plague kept returning for 400 years after the Black...
Ancient DNA reveals that plague repeatedly returned to Europe for more than 400 years after the Black Death, evolving into new lineages and spreading through trade, migration, and war. Researchers also...
View ArticleScientists find that “perfect” systems may be surprisingly fragile
Complex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids,...
View ArticleScientists solve a 50-year mystery and discover a new human blood group
Scientists have identified the genetic cause behind the mysterious AnWj blood group antigen, solving a puzzle that began in 1972 and establishing a new blood group system called MAL. The discovery...
View ArticleHidden gut defect that may explain why IBD keeps coming back
Researchers have uncovered a hidden molecular warning sign of inflammatory bowel disease (IBD) that can linger even when patients feel well and appear to be in remission. By studying around 900 human...
View ArticleScientists restore a brain protein and reverse signs of aging in mice
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring...
View ArticleThese blood thinners may have an unexpected benefit for Alzheimer’s patients
Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in cognitive...
View ArticleOzempic can change your body. Can it change your life?
Ozempic and other GLP-1 medications can improve blood sugar, weight, and cardiovascular health, but researchers found little evidence that they also improve mental health, employment, marriage, or...
View ArticleScientists discover cells that cheat death and rebuild damaged tissue
Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant to...
