    Gene links eyelids and early menopause

    A gene that orchestrates ovary and eyelid development may be the key to early-onset menopause.

  2. Health & Medicine

    Cancer cells have a ticket to ride

    Cancer cells may spread using the same system that immune system cells use to move through the body.

  3. Materials Science

    SQUID can catch concealed corrosion

    A new technology that can detect corrosion deep within aluminum aircraft parts has revealed that high concentrations of salt don't corrode hidden joints any more than low levels of salt.

  4. Materials Science

    Crystals step up to a new surface

    Researchers have made crystals that reversibly change their surface shape when hit by light.

  5. Consumer survey: Caged mink value water

    Even after 70 generations in captivity, caged American mink still seem to miss the swimming they would do in the wild.

  6. Phew! Orchid perfume turns revolting

    Orchids that can smell so alluring that bees try to mate with them can also smell repulsive to the insects.

  7. Arsenic Pollution Disrupts Hormones

    Researchers have found that arsenic thwarts the action of glucocorticoid hormones, suggesting a possible explanation of how long-term exposure to the metal in drinking water could cause cancer, diabetes, and other chronic diseases.

  8. Repression tries for experimental comeback

    A laboratory experiment finds that people have difficulty remembering words that they have intentionally tried to forget, providing support for Sigmund Freud's controversial concept of repression.

  9. Humans

    Science Talent Search winners shine bright

    Science Service and Intel announced the winners of the 2001 Science Talent Search.

  10. Earth

    Satellites verify greenhouse-gas effects

    Comparisons of data obtained from instruments that orbited Earth more than 25 years apart provide direct evidence that the planet's greenhouse effect increased significantly between 1970 and 1997.

  11. Chemical SOS not just for farm, lab plants

    The chemical screams for help that scientists have detected from agricultural plants under attack by pests in lab settings have now been heard in the wild.

  12. Health & Medicine

    Narcoleptic dogs still have their day

    Evidence from studies with dachshunds and poodles is suggesting that these small breeds may serve as better models than larger dogs, such as Labrador retrievers, for the more genetically complex narcolepsy in people.

  13. Physics

    Some swell materials give up their secret

    The discovery of a previously overlooked crystal structure in the best so-called piezoelectric materials may explain their remarkable amount of swelling when zapped by an electric field.

  14. Health & Medicine

    Drug helps against certain breast cancers

    In some patients, the drug trastuzumab, also called Herceptin, slows breast cancer that has spread to other organs.

  15. Learning in Waves

    Learning plays a largely unappreciated role in mental development, according to researchers who examine the variety of tactics children adopt as they attempt to solve problems in mathematics and other areas.

  16. Humans

    Errant Texts

    New studies lambaste popular middle-school science texts for being uninspiring, superficial, and error-ridden.
