Researchers have uncovered surprising evidence that anxiety may be controlled not by neurons but by two dueling groups of immune cells inside the brain. These microglia act like biological pedals--one pushing anxiety forward and the other holding it ...

Scientists studying aging found that sensory inputs like touch and smell can cancel out the lifespan-boosting effects of dietary restriction by suppressing the key longevity gene fmo-2. When overactivated, the gene makes worms oddly indifferent to .. ...

Smoking, vaping, or using both products significantly increases the likelihood of developing prediabetes and diabetes, and the risk is even higher among Hispanic, Black, and low-income groups. Researchers found that vaping alone raises prediabetes .. ...

Researchers have designed a smart drug that hunts down and breaks a little-known RNA that cancer cells depend on. The drug recognizes a unique fold in the RNA and triggers the cell to destroy it. Tests showed that removing this RNA slows cancer ...

Scientists have discovered strange microscopic structures in the blood of people with Long COVID--clusters of tiny microclots tangled together with sticky immune webs known as neutrophil extracellular traps, or NETs. These combined structures show up ...

Colchicine, a cheap and widely used gout drug, may help prevent heart attacks and strokes in people with cardiovascular disease. Trials involving nearly 23,000 patients show meaningful reductions in risk with low doses. Side effects were mostly mild ...

Scientists have uncovered a new environmental culprit behind liver disease: tetrachloroethylene (PCE), a chemical used in dry cleaning and household products. The study found that people with PCE exposure were three times more likely to develop ...

New research from the Technical University of Munich and Harvard Medical School reveals that popular GLP-1-based drugs, semaglutide (Ozempic) and tirzepatide (Mounjaro), not only promote weight loss but also significantly reduce the risk of heart ...

Scientists in Seoul have uncovered 15 gut bacterial species linked to coronary artery disease, showing that microbes can influence heart health far beyond digestion. Their findings reveal how shifts in gut microbial function -- including inflammation ...

GLP-1 drugs such as Ozempic and Wegovy may extend the lives of colon cancer patients, according to a major UC San Diego study. Patients on the medications had less than half the mortality rate of non-users. Researchers suspect the drugs' anti ...
