It may not be safe for men to get blood transfusions from women who have been pregnant. During a 10-year study, men who got transfusions from women with a history of pregnancy were 13 percent more likely to die than men who got transfusions from other men. It’s unclear why, but changes that occur in a woman’s immune system during pregnancy might play a role. [Read More About the Blood Transfusion Findings]

The main ingredient in magic mushrooms, known as psilocybin, may ease symptoms of depression, a small study finds. Researchers gave psilocybin to 20 people with depression, and found that the patients’ depressive symptoms declined (that is, the people felt better). However, there was no control group, and more research needs to be done, the researchers said. [Read More About the Magic Mushroom Research]
Dense clouds of ash and gasses expelled by the eruption of a volcano — such as Indonesia’s Mount Bromo, shown here in 2010 — can affect temperature and weather, sometimes for years.

Did volcanoes doom a dynasty in ancient Egypt? A group of researchers suggests that the aerosols that formed when ancient volcanoes erupted disrupted weather patterns, including the monsoons in Egypt. A drier monsoon season may have reduced Nile flooding, leading to fewer crops and famine, which could have sparked political unrest during the Ptolemaic dynasty.
