  1. Physics

    After 40-year prep, gravity test soars

    The Gravity Probe B satellite, which was built to test aspects of general relativity, finally hurtled into space.

  2. Nicotine limits cold adaptation

    A new study homes in on why smokers may have a harder time staying warm in frigid environments.

  3. Anthropology

    Neandertals may have grown up quickly

    A new analysis of fossil teeth indicates that Neandertals grew to maturity at a faster pace than people do.

  4. Humans

    Historical chemistry library wows scholars

    A new library in Philadelphia is home to one of the world's most extensive and valuable collections of historical chemistry texts.

  5. Earth

    Boats puff up outdoor carbon monoxide risk

    Large congregations of motorboats can produce enough carbon monoxide gas in open air to be hazardous to people.

  6. Health & Medicine

    Nanoparticles could mark spots for surgery

    A new molecule studded with magnetically active ions may soon help surgeons extract, with minimal cutting, lymph nodes likely to harbor cancer.

  7. Humans

    Plan B ruling is prescription for controversy

    Contravening a recent recommendation from one of its advisory panels, the Food and Drug Administration denied an application to make the emergency contraceptive known as Plan B available without a doctor's prescription.

  8. Tech

    Diagnostic gadget mixes and matches all in one

    Researchers have fabricated a miniature diagnostic lab that can detect disease-linked genes in a small sample of whole blood.

  9. Paleontology

    Fossil confirms that early arthropods molted

    A 505-million-year-old fossil provides hard proof of that ancient arthropods shed their exoskeletons during growth, just as their modern relatives do.

  10. Health & Medicine

    Bad Break: Homocysteine may weaken bones

    Elderly people with elevated concentrations of the amino acid homocysteine in their blood are more likely to break bones than are people with low amounts.

  11. Earth

    Underwater Pavement: Asphalt deposits cover parts of Gulf of Mexico

    Explorations of the seafloor in the southern Gulf of Mexico have revealed lavalike flows of asphalt that are home to a thriving ecosystem of microbes, mussels, tubeworms, and crabs.

  12. Physics

    Holey Water: Punctured fluid stays riddled

    Extreme vibrations and high concentrations of tiny particles, such as cornstarch, in water can create holes in the liquid.

  13. Toddlers’ Supersize Mistakes: At times, children play with the impossible

    Toddlers will sometimes try to climb into a toy car or otherwise treat small objects as if they were large ones, possibly because their brains occasionally fail to integrate visual information about object size with object identity.

  14. Expanding the Code: Engineered bacteria are genetic rebels

    Researchers have created a bacterium that can incorporate artificial amino acids into their proteins.

  15. Astronomy

    Back to the Beginning: Hubble’s infrared camera goes the distance

    Using the Hubble Space Telescope, researchers have identified 26 galaxies that may be the youngest and most distant known.

  16. Agriculture

    Rethinking Refuges? Drifting pollen may bring earlier pest resistance to bioengineered crops

    Pollen wafting from bioengineered corn to traditional varieties may be undermining the fight to keep pests from evolving resistance to pesticides.

  17. Physics

    The Rise of Antibubbles

    Tiny globules of water enclosed by thin shells of air in water that look like bubbles but don't act like them have recently become the objects of serious study.

  18. Math

    Glimpses of Genius

    By studying a puzzle that Archimedes pondered 2,200 years ago, mathematicians are obtaining new insights into its intriguing geometric structure.

    Letters from the May 15, 2004, issue of Science News

    Drug benefits There are added benefits to methotrexate and etanercept for rheumatoid arthritis patients, such as myself (“Two arthritis drugs work best in tandem,” SN: 3/13/04, p. 174: Two arthritis drugs work best in tandem). After a recent major flare-up, my rheumatologist put me on that therapy. Many people don’t realize that along with inflammation […]
