Researchers have confirmed the existence of an odd type of brain cell that other neuroscientists once thought might be only a technical quirk or error.
In animal studies, the weight-loss drug Ozempic has shown promise as an anti-addiction medicine. Whether it could work the same in humans remains to be seen.
New York City's normally good air quality rating recently plummeted to the worst of any major city in the world, as wildfire smoke drifted over the city from Canada.
