Sewage Divers, Elephant Vasectomist, and Whale Poop

Popular Science's "10 Worst Jobs in Science" this year (July issue) included the divers who scrub the walls of pits of sewage, toxins and nuclear waste; the elephant vasectomist (wielding a 4-foot-long laparoscope to deal with the 12-inch-wide testicles); carcass-preparers who ship cat, frog, shark and even cockroach bodies to be studied in science classes; the whale researcher who admitted she was "surprised" at "how much you could learn about a whale through its feces"; and the volunteers who lie still for up to 21 days to study the effects of weightlessness (for $2,000 a week).
