An experimental pill prevented a measles-like virus from spreading through the air or through close contact in ferrets. It worked when given shortly before or after exposure and also shortened illness and the period when infected animals remained contagious. Researchers say the d
A 25-year study found that frequent consumption of soda, sports drinks, and fruit juice beginning in childhood was linked to a higher risk of high blood pressure in adulthood. Swapping one daily drink for whole fruit, milk, or water could significantly reduce that risk.
Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant. The organoids and the particles they release could eventually guide more personalized treatments and provide new clues for diagnosing t
Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new drug targets and help researchers study da
Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing
Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive agin
A new experimental treatment may have found a way to outsmart glioblastoma’s toughest defense: the blood-brain barrier. Researchers used sugar-coated nanoparticles to ferry genetic instructions that restore a key tumor-suppressing protein directly into brain cancer cells. In mous
A growing Cyclospora outbreak has sickened more than 400 people in four states, and investigators are still searching for the contaminated food responsible. The CDC warns the actual number of cases is likely much higher and urges anyone with symptoms to seek medical care.
Going to the cinema, visiting museums, or attending concerts may do more than entertain. Researchers found that older adults who regularly participated in cultural activities tended to have bodies that functioned like those of people about three years younger. They believe strong
Scientists discover why peach fuzz can suddenly make you itch and more — today's wellness signal.
A newly discovered network of fine hairs and specialized nerve cells appears to form a dedicated system for sensing mechanical itch, offering fresh insight into why chronic itching occurs. Because humans show signs of having the same pathway, the research could pave the way for m
Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play a role in reducing the risk of
Stanford Medicine researchers have discovered a naturally occurring molecule that may suppress appetite and reduce body weight much like Ozempic, but without several of its common side effects. The molecule, called BRP, acts on a more targeted region of the brain involved in hung
A sulfur-based compound called LASSS appears to protect and supercharge a key protein involved in repairing damaged muscle. The discovery could eventually lead to new ways to slow muscle loss and preserve strength as people age.
An experimental pill prevented a measles-like virus from spreading through the air or through close contact in ferrets. It worked when given shortly before or after exposure and also shortened illness and the period when infected animals remained contagious. Researchers say the d
Ozempic, Wegovy, and similar drugs may deliver excellent health value, but covering them for millions of eligible patients could overwhelm insurance budgets. Researchers say better long-term support is needed and warn that low-cost compounded versions may carry serious safety ris
The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress. The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s.
A large study suggests that GLP-1 drugs including Ozempic and Mounjaro may slightly increase the risk of hair loss in people with type 2 diabetes. Compared with two other common classes of diabetes medications, GLP-1 users had a significantly higher rate of alopecia, though the a
A massive genetic study has identified nine new genes linked to hyperemesis gravidarum, the most severe form of pregnancy sickness, bringing the total number of known risk genes to ten. The discoveries provide fresh insight into why some women experience debilitating nausea and v
A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050. At the same time, fruit, vegetable, nut, and legume production could soar, creating a sweeping transformation of what th
A 25-year study found that frequent consumption of soda, sports drinks, and fruit juice beginning in childhood was linked to a higher risk of high blood pressure in adulthood. Swapping one daily drink for whole fruit, milk, or water could significantly reduce that risk.
Researchers have developed a fluoride-free gel that could help rebuild damaged tooth enamel, something the body cannot naturally replace once it is lost. Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic cracks and draws calcium and phosph
A plant-derived compound reduced swelling, inflammation, and joint damage in rats with rheumatoid arthritis. It also helped rebalance immune activity and improve the way certain fats were processed in the body. Researchers say the findings could lead to a new approach for treatin
Colorectal cancer is now the leading cause of cancer death among people under 50, and cases in younger adults continue to rise. Warning signs can include persistent bowel changes, recurring rectal bleeding, dark or narrow stools, unexplained weight loss, and fatigue. These sympto
