When actor Michael Douglas told a reporter that his throat cancer was caused by HPV contracted through oral sex, two themes emerged that had nothing to do with celebrity gossip. The first was incredulity — since when was oral sex related to throat cancer? Even the reporter thought he had misheard. The second was embarrassment. This was too much information, not only about sexual behavior but also about one’s partners. Douglas apologized, and maybe the world was not ready to hear the greater truth behind what he was suggesting. That was four years ago. (Schaaff, 4/2)

The first time cardiologist Sonia Tolani performed CPR outside a hospital was in 2009.She was on the subway in New York City, headed home from work, when she saw a man slump to the ground and stop breathing.

Eighteen months after joining a study on using marijuana to treat post-traumatic stress disorder, Johns Hopkins University has pulled out without enrolling any veterans, the latest setback for the long-awaited research. The university said its goals were no longer aligned with those of the administrator of the study, the Santa Cruz, Calif.-based Multidisciplinary Association for Psychedelic Studies (MAPS). MAPS said the dispute was over federal drug policy and whether to openly challenge federal rules that say medical cannabis research must rely on marijuana grown by the federal National Institute on Drug Abuse.
