  1. Humans


    Letters from the Jan. 3, 2004, issue of Science News.

  2. Health & Medicine

    Protein found central to ecstasy fever

    Scientists have identified a protein contributing to the high fevers that are sometimes generated by the drug ecstasy.

  3. Planetary Science

    Lunar finding doesn’t hold water

    A new radar study of craters at the moon's north and south poles reveals that neither region contains substantial amounts of frozen water.

  4. Earth

    Earth sometimes shivers beneath thick blankets of ice

    New analyses of old seismic data have distinguished the ground motions spawned by a previously unrecognized type of earthquake—quakes created by brief surges of massive glaciers.

  5. Earth

    Alaska shook, mountains spoke

    Small pulses in atmospheric pressure detected in Fairbanks soon after the magnitude 7.9 Denali quake on Nov. 3, 2002, suggest that the temblor literally moved mountains.

  6. Earth

    Newfound fault may explain quakes

    Tsunami simulations suggest that a newly discovered fault zone beneath the Atlantic Ocean could have released most of the seismic energy from three earthquakes that destroyed Lisbon, Portugal, on the morning of Nov. 1, 1755.

  7. Earth

    New technique dates glaze on desert rocks

    Scientists have developed a quick, easy, portable, and nondestructive way to determine the age of desert varnish, the mysterious dark coating that slowly develops on rocks in many arid regions of the world.

  8. Physics

    Topsy Turvy: In neutrons and protons, quarks take wrong turns

    Revved-up particles, namely quarks, spinning inside neutrons in the opposite direction to that of the neutrons themselves, challenge the prevailing model of how quarks behave.

  9. Animals

    Whale Haunt: Nursing, feeding spot found off south Chile

    A survey along the coast of southern Chile has turned up a previously undocumented blue whale hangout that seems to be a feeding ground.

  10. Earth

    My Own Private Bad-Air Day: Outdoor data underrate pollutant exposure

    Most people breathe in substantially more organic contaminants than airborne concentrations of such substances in their homes and communities would suggest.

  11. Paleontology

    Ancestral Handful: Tiny skull puts Asia at root of primate tree

    Researchers have unearthed the partial skull of the oldest known primate, a tiny creature that lived in south-central China 55 million years ago.

  12. Earth

    Blasts from the Past: Orbiting radar spots old nuclear-test sites

    A technique that analyzes satellite images to detect subtle ground motions often can perceive subsidence over underground nuclear-test sites, sometimes even if those tests occurred decades ago.

  13. Health & Medicine

    Pivotal Protein: Inhibiting immune compound slows sepsis

    By restraining the action of an immune system protein that can run amok, scientists experimenting on mice have reversed the course of severe sepsis.

  14. Tech

    Gene Screen: Ultrasensitive nanowires catch mutations

    Researchers have devised a nanowire sensor that binds to DNA molecules and produces an electrical signal almost instantaneously.

  15. Planetary Science

    Next Stop, Interstellar Space

    Data recorded by the venerable Voyager 1 spacecraft suggest the craft has either recently encountered or will soon enter a key region near the edge of the solar system.

  16. Earth

    Thin Skin

    Desert pavement, a delicate veneer of stones that covers the surface of up to 50 percent of the world's arid lands, is susceptible to being damaged by everything from multi-ton tanks to careless footsteps, and the resulting scars can take thousands of years to mend on their own.
