  1. Astronomy

    Oddball asteroid

    Astronomers have discovered an asteroid that takes only 6 months to go around the sun.

  2. Health & Medicine

    Breast milk may lower cholesterol

    Feeding a newborn baby breast milk instead of formula during the first month of life improves the child's cholesterol readings later on.

  3. Earth

    Killer weather on Mount Everest

    An analysis of weather patterns around Mount Everest in May 1996, when eight climbers died, suggests that a sudden drop in barometric pressure may have played a significant role in the deaths.

  4. Humans

    Simple water filter can nail arsenic

    Field tests suggest that people who live in areas with arsenic-tainted aquifers may be able to purify their drinking water by passing it through a low-tech, low-cost filter that includes a bed of iron nails.

  5. Astronomy

    Huge solar flares hit far-flung craft

    Spacecraft throughout the solar system have detected material spewed into space by a group of huge solar flares late last year.

  6. Astronomy

    Young World: NASA telescope reveals clues to newborn planet

    Astronomers have found signs of what may be the youngest planet known, plus the first signs ever of organic compounds in a region of dust that could evolve into a planet-forming region.

  7. Tech

    Protein Power: Solar cell produces electricity from spinach and bacterial proteins

    Researchers have fabricated a solar cell that uses photosynthetic proteins to convert light into electricity.

  8. Tech

    Tiny Tubes Brighten Bulbs: Nanotubes beat tungsten in lightbulb test—maybe

    Experiments suggest that lightbulbs with filaments made from carbon nanotubes outshine conventional bulbs.

  9. Death Waits for No One: Deferred demises take a couple of hits

    Two new reports challenge the idea that elderly people suffering from serious physical illnesses can prolong their lives just long enough to experience a personally meaningful event.

  10. Earth

    Geyser Bashing: Distant quake alters timing of eruptions

    A powerful earthquake that struck central Alaska on Nov. 3, 2002, changed the eruption schedule of some geysers in Wyoming's Yellowstone National Park, more than 3,100 kilometers away.

  11. Health & Medicine

  13. Got Milk? Dairy protein provides bone-forming boost

    A protein in milk stimulates bone-forming cells.

  14. Earth

    Dead Waters

    Coastal dead zones—underwater regions where oxygen concentrations are too low for fish to survive—are mushrooming globally, threatening to transform entire ecosystems.

  15. Materials Science

    Nice Threads

    Once researchers figure out how to spin strong fibers out of carbon nanotubes, real-world applications such as long-distance power-transmission cables, lightweight aircraft materials, and electronic textiles become feasible.

  16. Humans

    Letters from the June 5, 2004, issue of Science News

    Blackened reputation Again, humans are implicated in the promotion and distribution of our own misery (“Medieval cure-all may actually have spread disease,” SN: 4/3/04, p. 222: Medieval cure-all may actually have spread disease). However, if bitumen was wrongly credited with darkening the skin of mummified remains, what caused it? Robert FizekNewton, Mass. The coating on […]
