A sweeping review of nearly 100 studies has raised concerns about the mental health impacts of high-potency cannabis products. Researchers found strong links to psychosis, schizophrenia, and cannabis use disorder, while results for anxiety and ...

Scientists are racing to improve weight loss treatments beyond drugs like Ozempic and Wegovy, which are effective but plagued by nausea, bone loss, and weight regain. Tufts University chemists have created a new multi-target compound that goes beyond ...

Researchers have uncovered why smell often fades early in Alzheimer's: the brain's immune cells dismantle key nerve connections between the olfactory bulb and brainstem. Membrane changes in neurons send an "eat-me" signal to microglia, which ...

A single RSV vaccine dose is proving to be a powerful shield for older adults, significantly reducing hospitalizations and severe illness over two consecutive RSV seasons. While protection is strongest in the first year and declines somewhat in the . ...

A breakthrough pill, baxdrostat, has shown remarkable success in lowering dangerously high blood pressure in patients resistant to standard treatments. In a large international trial, it cut systolic pressure by nearly 10 mmHg, enough to ...

Beta blockers, used for decades after heart attacks, provide no benefit for patients with preserved heart function, according to the REBOOT trial. The massive study also found women faced higher risks when taking the drug. Experts say the results ...

New research suggests that exercise may not just make us feel younger--it could actually slow or even reverse the body's molecular clock. By looking at DNA markers of aging, scientists found that structured exercise like aerobic and strength training ...

Drinking nitrate-rich beetroot juice lowered blood pressure in older adults by reshaping their oral microbiome, according to researchers at the University of Exeter. The study found that beneficial bacteria increased while harmful ones decreased, ...

Scientists at Mount Sinai have created an artificial intelligence system that can predict how likely rare genetic mutations are to actually cause disease. By combining machine learning with millions of electronic health records and routine lab tests ...

Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like state. While this messy shortcut helps tissues ...
