A preliminary analysis from Boston researchers ties greater exposure to artificial light at night to heightened stress activity in the brain, arterial inflammation, and a higher risk of major heart events. The work will be presented at the American Heart Association’s Scientific Sessions 2025 in New Orleans on November 7–10 and frames light pollution as a potentially modifiable environmental factor.
Brazil's Anvisa approved on Monday, February 2, 2026, the expansion of therapeutic indications for semaglutide, the active ingredient in Wegovy and Ozempic. Wegovy can now be used to reduce the risk of heart attacks and strokes in adults with cardiovascular disease and overweight, while Ozempic is indicated for type 2 diabetes associated with chronic kidney disease. The agency is also reviewing a request for an oral version of Wegovy.

A comprehensive review in Beverage Plant Research concludes that evidence from human studies most strongly supports an association between tea consumption—particularly green tea—and lower risks of cardiovascular disease, obesity, type 2 diabetes and some cancers, while calling evidence for brain and muscle benefits “promising” but less settled. The authors also caution that bottled and bubble tea products, which can include added sugar and other additives, may blunt tea’s potential advantages.
