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 challenge routine supplementation for prevention and point instead toward strategies such as…
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. Researchers identified eight widely used preservatives associated with hypertension, although the observational study cannot prove they were directly responsible.
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 developed a method to date ancient plague genomes more precisely, linking many of them…
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 gut biopsies and patient-derived mini-intestines, the team found that intestinal cells can remain…
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 familiar pathogens could leave the world vulnerable when rare but deadly viruses suddenly reemerge.
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 could make it much easier to find extremely rare AnWj-negative patients and donors and…

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 function than those using warfarin or no blood thinners. The effect was modest each year but…
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 Menin reversed several age-related changes, while the amino acid D-serine improved cognition, hinting at a…
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 overall well-being. The findings suggest the drugs’ broader life effects may be subtler than their dramatic physical health…
The U.S. Food and Drug Administration today approved Fayuvi (rebisufligene etisparvovec-hopf), the first treatment for pediatric patients with mucopolysaccharidosis type IIIA (MPS IIIA), also known as Sanfilippo syndrome type A.

A natural compound produced by gut bacteria after digesting foods such as pomegranates, walnuts, and berries may help repair and protect the intestinal lining. The discovery reveals a surprising beneficial side of an inflammatory pathway and could inspire more targeted treatments for Crohn’s disease and…
Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help control how quickly electrical signals travel through…
Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an antioxidant defense that tumors use to survive intense oxidative stress. In an early clinical trial, it…
Scientists found that black and green Japanese rice contain unusual, potentially beneficial fats and may be digested more slowly than ordinary white rice. The combination could make these colorful varieties promising ingredients for foods designed to support blood sugar and metabolic health.
Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new treatments that target the skull directly.
Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong part of a cell, an immune sensor called cGAS…
by Reuben Granich, Somya Gupta, Isabelle Munyangaju, Mike Ruffner Summary points In 2015, a survey-based analysis across 16 sub-Saharan African countries estimated that nearly half of people living with HIV were undiagnosed, implying ~11 million people in the region were outside the treatment cascade. However…

Eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles, according to MRI scans of 615 adults at risk for knee osteoarthritis. Surprisingly, the association remained even after researchers accounted for calorie intake, physical activity, and other factors. Fatty changes in these…
A naturally occurring molecule called erucamide may help the retina fight back against diseases that cause progressive vision loss. Restoring the molecule activated protective immune responses that helped stabilize retinal tissue and slow aspects of degeneration in preclinical models.
Older adults who changed the balance of fat, carbohydrates, and animal protein in their diets showed signs of reduced biological age after just four weeks. The strongest result appeared in participants eating an omnivorous, lower-fat, higher-carbohydrate diet.
Simply smelling chocolate helped men complete more leg extension repetitions without making the workout feel harder, with dark chocolate producing the strongest effect. The researchers think familiar food aromas may influence appetite and motivation by making the brain anticipate eating.
Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer’s and other neurodegenerative diseases. One of the biggest shifts occurred between about ages 50 and…
