In 2019, the FDA approved Spravato for patients with major depressive disorder who hadn't responded to other treatments. Now, the agency is adding patients who are having suicidal thoughts or have recently attempted to harm themselves or take their own lives. Sarah Silbiger/Getty Images hide caption

Blood plasma — the yellowish, cell-free portion that remains after red and white blood cells have been filtered out by a machine and returned to the plasma donor — is rich with antibodies. Plasma from recovered COVID-19 patients might prove useful in preventing infection as well as in treatment, scientists say. Lindsey Wasson/Reuters hide caption

This light micrograph from the brain of someone who died with Alzheimer's disease shows the plaques and neurofibrillary tangles that are typical of the disease. A glitch that prevents healthy cell structures from transitioning from one phase to the next might contribute to the tangles, researchers say. Jose Luis Calvo/ Science Source hide caption
