  1. Genetics

    Selfish genes hide for decades in plain sight of worm geneticists

    Crossing wild Hawaiian C. elegans with the familiar lab strain reveals genes that benefit themselves by making mother worms poison offspring who haven’t inherited the right stuff.

  2. Animals

    Orangutans take motherhood to extremes, nursing young for more than eight years

    Weaning in orangutans has been tricky to see in the wild, so researchers turned to dental tests to reveal long nursing period.

  3. Environment

    When it’s hot, plants become a surprisingly large source of air pollution

    During a heat wave, trees and shrubs can sharply raise ozone levels, a new study shows.

  4. Health & Medicine

    Transplanted stem cells become eggs in sterile mice

    Sterile mice that received transplanted egg-making stem cells were able to have healthy babies.

  5. Quantum Physics

    Quantum tractor beam could tug atoms, molecules

    The wavelike behavior of quantum particles could be harnessed to move atoms.

  6. Health & Medicine

    40 more ‘intelligence’ genes found

    A study of nearly 80,000 people turns up 40 genes that may have a role in making brains smarter.

  7. Anthropology

    European fossils may belong to earliest known hominid

    With new analyses of Graecopithecus fossils from Greece and Bulgaria, researchers argue for possible hominid origins in Europe, not Africa.

  8. Life

    How a flamingo balances on one leg

    Flamingos’ built-in tricks for balance might have a thing or two to teach standing robots or prosthesis makers someday.

  9. Earth

    Deep heat may have spawned one of the world’s deadliest tsunamis

    The 2004 Indonesian quake was surprisingly strong because of dried-out, brittle minerals far below.

  10. Planetary Science

    Juno spacecraft reveals a more complex Jupiter

    NASA’s Juno spacecraft has sent back unexpected details about Jupiter, giving scientists their first intimate look at the giant planet.

  11. Physics

    LIGO snags another set of gravitational waves

    Two black holes stirred up the third set of gravitational waves ever detected.

  12. Health & Medicine

    In 1967, researchers saw the light in jaundice treatment

    Researchers discovered how to use light to treat babies with jaundice 50 years ago. But questions remain about the technique’s effectiveness in some cases.

  13. Life

    Ladybugs fold their wings like origami masters

    Ladybug wings could lead to new foldable technologies.

  14. Life

    Mouse sperm survive space to fertilize eggs

    Sperm freeze-dried and sent into space for months of exposure to high levels of solar radiation later produced healthy baby mice.

  15. Planetary Science

    TRAPPIST-1’s seventh planet is a chilly world

    Follow-up observations of TRAPPIST-1 and its seven planets reveals details about the outermost one.

  16. Health & Medicine

    Global access to quality health care has improved in the last two decades

    Health care quality and availability improved worldwide from 1990 to 2015, but the gap between countries with the lowest and highest levels of care widened.
