    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.

    Underage Spiders: Males show unexpected interest in young mates

    To the surprise of biologists, a male Australian redback spider will mate with a juvenile female before her reproductive tract has an external opening. The male bites through the immature female's outer covering and by doing so, protects his own life.

    This discovery adds a new twist to a textbook example of extreme mating practices. Until now, biologists had focused on these...

    Fish as Farmers: Reef residents tend an algal crop

    A damselfish cultivates underwater gardens of an algal species that researchers haven't found growing on its own.

    The special alga could be the fishy version of people's domesticated crops, says Hiroki Hata of Kyoto University in Japan. Growth tests of the alga, surveys of its distribution, and genetic analyses support that idea, he and Makoto Kato say in an upcoming Biology...

    Social jet lag: Need a smoke?

    From Munich, at the Euroscience Open Forum meeting

    People who have a hard time waking in the morning because their bodies' internal clocks are out of sync with their sleep schedules are said to have "social jet lag." Researchers in Europe have determined that the phenomenon strongly correlates with smoking.

    Battling one's biological clock can leave people weary in the same way as...

    Terrific Timekeeper: Optical atomic clock beats world standard

    Physicists in Colorado say that they've refined an innovative atomic clock to be more precise than the breed of clocks that's been the best for 50 years.

    The advance indicates that the reign of atomic clocks tuned to the element cesium is coming to an end, says physicist James C. Bergquist of the National Institute of Standards and Technology (NIST) in Boulder, Colo., who led the...

    Fruity Relief for Weekend Warriors

    After 2 years of planning, you're finally able to afford a long weekend off for that ski trip to Aspen. The first day out, you put in 5 or 6 hours working your way down the slopes. You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

    Be Good to Your Gums, Bite Into Whole Grains (with recipe)

    After years of whole grains being relegated to niche markets and vegetarian recipes, these fiber-based foods have enjoyed a surge in popularity. Propelling this move has been the publication of study after study showing the benefits of whole-grain foods such as oatmeal, brown rice, muesli, and millet. These benefits range from heart health and weight loss to better blood-sugar control.

    Dementia off the Menu: Mediterranean diet tied to low Alzheimer's risk

    People who eat a Mediterranean-style diet are less likely than their peers to develop Alzheimer's disease, according to new research on elderly Manhattan residents. The study is the first to link brain benefits to a comprehensive dietary pattern rather than to individual foods or nutrients, say the scientists who performed the research.

    Traditional Mediterranean menus are rich in...

    Wary male spiders woo lifelessly

    Certain male spiders confront the threat of a cannibalistic female with a novel tactic: They play dead while having sex.

    Nursery spiders (Pisaura mirabilis) belong to a family known for violent females that, on occasion, attack and eat males attempting courtship, notes Trine Bilde of Århus University in Denmark.

    Biologists already knew that males of this species have one method...

    Meat Poses Exaggerated Cancer Risk for Some People

    Last year, the federal government's National Toxicology Program confirmed what many researchers had long been reporting: The heterocyclic amines that form in overcooked meat can trigger colon cancer in animals and probably do the same in people. Now, researchers studying mice have identified a gene that is needed to keep individual animals from becoming especially vulnerable to these...
