In a study that included genetic data from more than 1 million people, scientists started to unravel the genetics of cannabis use disorder.

Declines in measles vaccination during the COVID-19 pandemic have been tied to an uptick in measles cases, deaths and major outbreaks worldwide.

Hundreds of endoscopy patients at a Massachusetts hospital were potentially exposed to blood-borne pathogens, the health care facility reported.

Researchers have raised concerns about the high number of kids and preteens consistently taking melatonin, because the long-term safety of the sleep aid has not been well-studied.

Using a CRISPR-guided technique called "base editing," scientists edited the genes of liver cells in 10 people's bodies.
