    Toxic Tides: Another reason to worry about hurricanes

    When Hurricanes Charley, Frances, Ivan, and Jeanne struck Florida in the summer of 2004, they killed 116 people, left thousands homeless, and caused billions of dollars in damage. Now, scientists suggest that the storms may also have triggered an intense, widespread Gulf of Mexico algae bloom that afflicted the state's western coast throughout 2005.

    Commonly called red tides...

    Leggiest Animal: Champ millipede located after 79-year gap

    A millipede species with up to 750 legs, the most recorded on any animal, has turned up in its tiny native range in California after decades with no sightings, biologists say.

    The Illacme plenipes millipede has never been found beyond a 0.8-square-kilometer area in San Benito County, several hours south of San Francisco, explains millipede taxonomist Paul E. Marek of East...

    Ancient Wisdom: Chinese extract may yield diabetes treatment

    A plant extract used in traditional Chinese medicine to treat type 2 diabetes could form the basis for new treatments for the disease, scientists now report.

    In some cases of type 2 diabetes, a person's pancreas doesn't produce enough insulin, a hormone that prompts cells to take in blood sugar. Studies have indicated that a substance called uncoupling protein 2 (UCP2),...

    All the Rage: Survey extends reach of explosive-anger disorder

    A mental disorder that encompasses a wide range of recurring, hostile outbursts, including domestic violence and road rage, characterizes considerably more people than previous data had indicated, a national survey finds.

    At some point in their lives, between 5.4 percent and 7.3 percent of U.S. adults qualify for a diagnosis of intermittent explosive disorder, concludes a team led by...

    Walking on Water: Tree frog's foot uses dual method to stick

    Tree frogs' feet aren't nearly as powerful as those of the well-studied gecko, but their traction is good enough that they can grip the underside of a wet, slick leaf. Now, researchers have evidence that the tree frog's foot may be surprisingly sophisticated.

    Unlike a gecko's toe, which uses dry, sticky hairs to clutch a surface (SN: 8/31/02, p. 133: Available to subscribers...

    Mini Solar Systems? Astronomers find disks around planet-size objects

    Planet-making disks of gas, dust, and ice are known to form around stars and brown dwarfs. But now, disks with the potential to form planets, or at least moons, have been found outside the solar system orbiting objects that themselves are no heftier than planets.

    A study reported this week at a meeting of the American Astronomical Society in Calgary, Alberta, follows up on...

    Homegrown Defender: Urinary infections face natural guard

    Bacteria are adept at sneaking past our defenses, succeeding most often when swallowed, inhaled, or given free passage via a cut or scratch. But over the past 2 decades, scientists have found that even before the immune system can gin up a response to such intruders, built-in antimicrobial agents in the intestines, lungs, and skin act as a first line of defense. A new study shows that one of...

    Cooked garlic still kills bacteria

    From Orlando, Fla., at the American Society for Microbiology meeting

    Researchers have long known that chemicals isolated from raw garlic can kill a wide variety of bacteria, but the cooked herb hadn't been tested. A new study suggests that cooked garlic can still kill bacteria, though less efficiently than does a raw bulb.

    Can supplements nix kidney stones?

    From Orlando, Fla., at the American Society for Microbiology meeting

    Certain bacteria seem to degrade the compound that forms kidney stones. However, the vast majority of commercially available probiotic supplements, which contain a variety of bacteria strains, don't appear to have this effect, according to new research.

    During their lifetimes, about 5 percent of adults will get...

    Dive suits could spread disease

    From Orlando, Fla., at the American Society for Microbiology meeting

    Divers' wetsuits can harbor bacteria that cause diseases in coral and people, a new study suggests. The finding could lead to new guidelines for cleaning gear after dives.

    Coral reefs are rapidly declining worldwide, and infectious diseases of the microscopic animals living within them seem to be a major cause....
