    Slime Dwellers

    Put on your snorkel gear and get close to coral—really close—and you can spy a thin layer of surface slime. Produced continually, and often in prodigious amounts, this mucus can be anything from a thick, soupy liquid to gummy gel. Corals expend significant energy making and replenishing these water-soluble jackets, but scientists have struggled to understand the payoff for this effort.

    Longer work hours may warm climate

    U.S. employees work an average of 16 percent more hours per year than most of their European counterparts do—often with no increased productivity—a new study notes. A longer workday requires more energy for heat, light, and power, and the atmospheric emissions from that extra energy use contribute substantially to U.S. releases of greenhouse gases, including carbon dioxide.

    U.S. workers...

    Smoke Out: Bartenders' lungs appreciate ban

    Pub workers in Scotland breathed easier and showed better respiratory health shortly after a nationwide ban on smoking inside public places went into effect earlier this year, scientists report.

    Sea Turtles—What Not To Eat

    At dozens of beaches around the world, huge female sea turtles come back each year at about the same time. They slowly haul themselves out of the water near the places they themselves hatched, dig shallow holes in the sand, and lay clutches of eggs. The predictability of the turtles' return has made capture of the endangered reptiles and their eggs a reliable bonanza for poachers.

    Battle of the Hermaphrodites

    Anybody who's ever mused that the world would be better if men got pregnant needs to talk to Nico Michiels. And so does anybody who's asked—or sung—"Why can't a woman be more like a man?" Michiels has seen that world, or at least a version of it, and he's even got pictures to show. It's not pretty, he says.

    Many snails, slugs, and worms are so-called...

    Are pollutants shrinking polar bear gonads?

    The more polluted a polar bear's fat, the more likely its reproductive organs will be undersize, scientists find.

    They collected gonads from 55 male and 44 female bears killed legally by subsistence hunters in east Greenland. The scientists then tested the bears' fat for pollutants that might affect sex hormones.

    Especially in immature males, testis length diminished with...
