Eating five servings of fruits and vegetables may not be enough if you’re missing foods rich in flavanols, a group of compounds linked to better heart health. Researchers found that choices like blackberries, plums, apples, broad beans, cherries, and green tea can dramatically increase flavanol intake.

A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models. The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach.

A new biomaterial made from jackfruit latex, pomegranate peel, and simvastatin could transform the treatment of severe gum disease. Early tests suggest it not only combats infection and inflammation but may also help rebuild lost bone and tissue around teeth.

Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off the damage that eventually leads to the disease’s most recognizable brain changes.

Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbreaks that wiped out many children and young teenagers.

A major study of more than 112,000 people found that eating foods containing common preservatives may be linked to a higher risk of high blood pressure and heart-related diseases. Researchers tracked participants for up to eight years and discovered that people consuming the highest amounts of certain preservatives had significantly greater risks of hypertension, heart attack, stroke, and other cardiovascular problems.

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies.

A Rutgers study suggests GLP-1 drugs such as Ozempic and Wegovy may weaken the link between impulsive tendencies and violent behavior. The surprising finding hints that these medications could affect how people act on impulses, though researchers stress that cause and effect have not been proven.

Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed significantly higher anxiety as adults, even long after exposure had ended. The animals were more hesitant to explore open spaces and spent more time frozen in place, classic signs of anxiety in rodents.

A small clinical trial suggests that probiotics may offer a surprising mental health boost for older adults with depression. Seniors who took a daily probiotic alongside their regular antidepressant treatment experienced slightly greater improvements in depression and anxiety symptoms than those who received a placebo.
