For the first few years Liz Evans worked at the Portland Hotel Society, a network of homeless shelters in central Vancouver, she would arrive at her job already exhausted. On her morning walk through Downtown Eastside—a neighborhood infamous as the poorest zip code in Canada—she stepped over drug addicts passed out in doorways and sidled around alleys where people would cook dope and shoot up in broad daylight. It was 1993, and Vancouver was in the throes of an HIV epidemic. Tens of thousands of impoverished injection drug users were crammed into a fifteen-block radius. The Portland Hotel Society was one of the few housing projects in the city that welcomed drug addicts, and working there felt like triage. Evans, a nurse, trained her staff to intervene when the residents overdosed. “It was such a painful time,” Evans says. “These weren’t people who were partying or using drugs to have fun. They were poor and sick and dying.”
Last week, a small drug company called Sprout Pharmaceuticals announced that its version of “female Viagra”—a medication designed to enhance women’s libidos—was going back for yet another battery of tests.

Five great extinctions have occurred in the history of Earth. Now, in The Sixth Extinction: An Unnatural History, journalist Elizabeth Kolbert eulogizes the decline of a handful of species and makes the case that a new mass die-off is under way. Industrial processes that pump carbon dioxide into the ocean are making life untenable for the thousands of plants and creatures that live in its depths, especially the vast but fragile coral reefs. Whole populations of bats in the northeastern United States have been decimated by a fungus brought to New England by an unsuspecting European traveler. The great auk, an extinct bird, suffered its last stand on an Icelandic island after being relentlessly hunted for just a few decades.
