    Why a turkey helps a pal find a mate

    A new study shows how the classic idea of kin selection could explain why male turkeys cruise in pairs, even though only one of them will win a mate.

  2. Astronomy

    It’s a star, but not much of one

    Astronomers have discovered the smallest star known.

  3. Earth

    Volume of glaciers and ice caps is estimated

    New topographic data have enabled scientists to estimate the volume of water trapped in the ice caps and glaciers outside of Antarctica and Greenland and to predict how high the sea level would rise if this ice melted.

  4. Planetary Science

    Assault on Mars

    A Mars rover has discovered a patch of soil that's the saltiest place known on the Red Planet, an indication that water once coursed through the region.

  5. Health & Medicine

    Molecular decoy thwarts Alzheimer’s

    Biomedical engineers have developed polymer molecules that bind to and block the activity of proteins associated with Alzheimer's disease.

  6. Chemistry

    Stopping wool from shrinking

    Treating wool with a fungal enzyme not only prevents the fibers from shrinking but also is more environmentally friendly than using conventional chemical treatments.

  7. Tech

    X rays detect fingerprints

    Analytical chemists have developed a method that visualizes elusive fingerprints with X rays.

  8. Chemistry

    Expanding the genetic code

    In an effort to explore the mechanisms of evolution, researchers have designed an unnatural chemical base and inserted it into synthetic DNA in a test tube.

  9. Earth

    Hit Again: December temblor probably caused new Sumatran quakes

    Seismic activity that rattled the Indonesian region early this week, including a quake that measured a whopping magnitude 8.7, was triggered by December's massive tsunami-spawning earthquake, scientists suggest.

  10. Physics

    Pinstripe Electricity: Novel fuel cell relies on thin, aqueous streams

    A promising new type of fuel cell exploits microstreams of water, which behave like flows of gooey honey.

  11. Follicle Size Matters: Hormone regimen may reduce pregnancy success

    Hormone injections used to induce livestock and women to ovulate could force eggs to leave ovarian follicles before they are fully mature and thereby jeopardize pregnancy outcomes.

  12. Earth

    Breeding Parasites Along with Fish: Do sea lice from salmon farms spread far?

    Marine parasites known as sea lice spread readily from farmed salmon to passing wild fish, according to a controversial study conducted in British Columbia.

  13. Tech

    Leak Locator: Ultrasound for finding holes in spacecraft

    Researchers have devised a way to pinpoint leaks in spacecraft by listening to ultrasound waves traveling through the ship's hull.

  14. Little Brains That Could: Bees show big-time working memory

    Even though a honeybee's brain could fit on the head of a match, the creature's working memory is nearly as effective as that of a pigeon or a monkey.

  15. Astronomy

    Star Packed: Super cluster is first to be detected in Milky Way

    Astronomers have detected the most massive and densest cluster of young stars ever detected in the Milky Way, a finding that could shed light on how stars formed in the early universe.

  16. Ecosystems

    Quick Fix: How invasive seaweed repairs its wounds

    Scientists have discerned the chemistry underlying the rapid wound-healing process in an invasive green alga that is wreaking havoc in the Mediterranean Sea.

  17. Health & Medicine

    Still Hungry?

    New research indicates that diet and lifestyle can affect the body's production of a hunger hormone in ways that might unwittingly foster overeating.

  18. Full Stem Ahead

    Before stem cells can fulfill the promise of treating deadly diseases, problems with the cells' biology and government regulations limiting their use must be solved.

    Letters from the April 2, 2005, issue of Science News

    Zoom in, drop out On reading the interesting research on droplets (“Dial-a-Splash: Thin air quells liquid splatter,” SN: 2/12/05, p. 99), I noticed that the two droplets shown in the photos at the moment of first contact have different shapes. In air at normal pressure, the droplet has the characteristic hamburger-bun shape. In contrast, the […]
