  1. Health & Medicine

    Immune reaction to poison gas brings delayed effects

    Researchers have a new understanding of why some survivors of carbon monoxide poisoning later develop concentration problems, personality changes, or sensory impairments.

  2. Animals

    Owls use tools: Dung is lure for beetles

    Burrowing owls' habit of bringing mammal dung to their burrows attracts edible beetles and counts as form of tool use.

  3. Earth

    Compost reduces landfill gas

    Field tests suggest that covering solid waste with compost instead of conventional soil could reduce methane-gas emissions from landfills.

  4. Health & Medicine

    Juice could ward off cancer in smokers

    Drinking grapefruit juice every day could reduce the risk of developing cancer from smoking.

  5. Chemistry

    Molecular machines split water

    Hydrogen derived from molecular machines that use solar energy to split water, rather than hydrogen from fossil fuels, could drive future fuel cell vehicles.

  6. Physics

    Gold quantum dots

    Scientists have created a new type of quantum dot that could find applications in everything from biological imaging to computer displays.

  7. Chemistry

    Meteorites may have delivered phosphorus

    Meteorites may have supplied enough phosphorus to prebiotic Earth to spawn the first signs of life.

  8. Earth

    No Deep Breathing: Air pollution impedes lung development

    Spending one's childhood in a community with polluted air stalls lung development roughly as much as does having a mother who smokes.

  9. Earth

    Cool Harvest: Frost on sea ice may boost atmosphere’s bromine

    Frost flowers, the delicate crystals that sometimes grow atop fresh sea ice, can be a substantial source of ozone-destroying bromine in lower atmosphere near the poles.

  10. Materials Science

    Model Growth: Simulations expose branching nature of polymer crystals

    Using computer models, scientists have uncovered previously unknown facets of the physics underlying polymer crystal growth.

  11. Health & Medicine

    An Exploitable Mutation: Defect might make some lung cancers treatable

    Nonsmokers who develop lung cancer are more likely than their smoking counterparts to have a mutation in the gene encoding epidermal growth factor receptor.

  12. Materials Science

    Falling into Place: Atom mist yields nanobricks and mortar

    Researchers have induced tiny particles of nickel to spontaneously assemble into exceptionally uniform, three-dimensional arrays of macroscopic size.

  13. A Very Spatial Brain Defect: Gene disorder blocks neural path for vision

    Among its many unusual symptoms, the genetic disorder called Williams syndrome robs people of depth perception and the ability to visualize how different parts assemble into larger objects.

  14. Animals

    Super Bird: Cooing doves flex extra-fast muscles

    Muscles that control a dove's cooing belong to the fastest class of muscles known.

  15. Planetary Science

    A really cool map

    A new infrared image of Saturn's rings provides the most detailed temperature map ever taken of these icy particles.

  16. Health & Medicine

    Figuring Out Fibroids

    Researchers now have a better understanding of which women develop fibroids and what causes them.

  17. Agriculture

    The Ultimate Crop Insurance

    A new treaty renews hope that the waning diversity in agricultural crops can be slowed, and important genes preserved, both in the field and in gene banks.

  18. Humans

    Letters from the September 11, 2004, issue of Science News

    Say what? I don’t think anyone should be surprised that squirrels have figured out how to say “nyah, nyah” to rattlesnakes (“Ultrasound alarms by ground squirrels,” SN: 7/3/04, p. 14: Ultrasound alarms by ground squirrels). After all, it’s what they’ve been saying to cats, dogs, and bird-feeder owning humans for years. R. Kelly WagnerAustin, Texas […]
