The National Institutes of Health is sunsetting its influential COVID-19 treatment guidelines, used by millions of doctors to guide care during the pandemic.

Scientists are optimistic that gene-edited animals could provide a new source of organs for transplantation. Pig organs modified to minimize rejection are now being tested in humans.

After seven years of research, the findings shed light on the long-neglected illness. Scientists say the results could lead to future trials for potential treatments.

A doctor argues that the current focus on fighting obesity with drugs like Ozempic ignores the bigger picture: We need a medical system and society that support healthy life habits.

Scientists report that gene therapy restored at least some hearing and speech for five out of six children with a rare form of genetic deafness.
