    Troubling Meaty 'Estrogen'

    Women take note. Researchers find that a chemical that forms in overcooked meat, especially charred portions, is a potent mimic of estrogen, the primary female sex hormone. That's anything but appetizing, since studies have linked a higher lifetime cumulative exposure to estrogen in women with an elevated risk of breast cancer.

    Indeed, the new finding offers a "biologically...

    Old plants were lost in the grass

    An obscure family of small, narrow-leaved water plants that have for years been classified as oddball relatives of grasses turns out to represent one of the most ancient surviving lineages of flowering plants, researchers say.

    New Estimates of the Shark-Fin Trade

    Immense numbers of sharks each year are slaughtered for their fins—not meat, just their fins. This harvest helps feed a growing appetite throughout Asia for a popular soup, one with snob appeal comparable to that of caviar.

    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.

    Leaden Chocolates

    Here's something that might give you pause after Halloween: Chocolates are among the more lead-contaminated foods. A new study has probed the source of chocolate's lead and concludes it's not the cocoa bean. Its concentrations of the toxic metal were among the lowest recorded for any foodstuff.

    Physiology or Medicine

    Two Australian scientists who showed that bacteria can cause stomach ulcers have won the 2005 Nobel Prize for Physiology or Medicine.

    The researchers made their discovery 23 years ago, at a time when ulcers were thought to result mainly from excess stomach acid brought on by stress and spicy food. In 1979, J. Robin Warren, a pathologist at the Royal Perth...

    Empty Nets

    In the 1850s, 43 schooners from a single port, Beverly, Mass., plied the North Atlantic's Scotian shelf, which is prime cod territory in Canadian waters. Over the sides of the ships, crews dropped lines with single hooks and doggedly jigged their bait along the seafloor to entice the big predatory fish. Although the combined fleet used fewer than 1,200 hooks, the ships' logs indicate that...
