  1. Planetary Science

    Rovers in overtime

    NASA has extended the missions of the twin Mars rovers by 5 months, through September 2004.

  2. Health & Medicine

    CT scan no match for colonoscopy

    Colonoscopy is better at detecting potentially dangerous colon polyps than computed tomography scanning is.

  3. Earth

    Hurricanes churn up life-nurturing brews

    Images of the North Atlantic taken from orbit suggest that hurricanes churn the ocean's surface enough to bring cool, nutrient-rich waters to the surface, thereby stimulating algal blooms that can last for weeks.

  4. Health & Medicine

    Experimental drug boosts HDL counts

    An experimental drug can dramatically increase blood concentrations of high-density lipoprotein, the beneficial cholesterol.

  5. Body’s sweet move can protect heart

    Animal studies suggest that the body attempts to protect itself from heart attacks during brief periods of oxygen deprivation by temporarily modifying heart-muscle proteins.

  6. Health & Medicine

    Proteins mark ALS

    Scientists reported finding what appears to be the first diagnostic test for Lou Gehrig's disease, potentially shaving a year off of when targeted treatment for the disease can begin.

  7. SIDS trigger? It’s too darn hot

    Overheating, as might occur if a baby were swaddled in a warm room, might predispose some babies to prolonged breathing lapses and sudden infant death syndrome, animal experiments indicate.

  8. Health & Medicine

    Exercise boosts sugar’s taste

    Studies in runners and in animals indicate that exercise increases an individual's sensitivity to sweetness.

  9. Tech

    Injectable Medibots: Programmable DNA could diagnose and treat cancer

    Researchers have created a miniature DNA computer that can detect cancer genes in a test tube and respond by releasing a drug.

  10. Animals

    Din among the Orcas: Are whale watchers making too much noise?

    Whale-watching boats may be making so much noise that killer whales off the coast of Washington have to change their calls to communicate over the racket.

  11. Archaeology

    Stone Age Combustion: Fire use proposed at ancient Israeli site

    A Stone Age site in Israel contains the oldest evidence of controlled fire use in Asia or Europe, from around 750,000 years ago, a research team reports.

  12. Earth

    Harm from Plastic Additive Challenged: Early exposure shows no ill effects

    Presumed exposure shortly after birth to a chemical ingredient in plastics shows no evidence of disrupting development in people, according to a small study of teens who, as newborns, received intensive medical care involving plastic hospital equipment.

  13. Health & Medicine

    Unsettling Association: Dental X rays linked to low-birth-weight babies

    Getting dental X rays while pregnant might increase a woman's risk of giving birth to a low-birth-weight baby.

    Mouse Mourned: Yoda dies at age 4

    An age-defying laboratory mouse known as Yoda died peacefully in his cage in Ann Arbor, Mich., on April 22, at the age of 4 years and 12 days.

  15. Earth

    It’s a Gas: Trees emit unknown volatile substances

    The chemical reactions taking place just above a northern Michigan forest hint that trees there and elsewhere may be emitting highly reactive gaseous substances that scientists haven't yet identified or directly detected.

  16. Physics

    The Electron’s Other Charge: Workhorse of electricity shows its weak side

    Although electrons are nonnuclear particles, they exert a feeble nuclear force on each other when they snuggle up close, a new experiment shows.

  17. Chemistry

    Space Invaders

    Recent astronomical observations and sophisticated lab experiments portray space as a breeding ground for complex organic molecules, the likes of which may have jump-started life on Earth.

  18. Health & Medicine

    Coffee, Spices, Wine

    Several dietary agents, including coffee, wine, and cinnamon, appear to restore some of the body's responsiveness to insulin, potentially slowing diabetes' onset or ravages.
