    Cosmology

    These stars may have been born only 250 million years after the Big Bang

    Scientists find evidence that stars were forming just 250 million years after the universe was born.

  2. sea slug
    Neuroscience

    RNA injected from one sea slug into another may transfer memories

    Long-term memories might be encoded in RNA, a controversial study in sea slugs suggests.

  3. red-eared slider turtle
    Life

    There’s a genetic explanation for why warmer nests turn turtles female

    Scientists have found a temperature-responsive gene that controls young turtles’ sex fate.

  4. northern climate
    Genetics

    Adapting to life in the north may have been a real headache

    A cold-sensing protein has adapted to different local climates, also affecting risk of migraine.

    A new kind of polymer is fully recyclable: It breaks down into the exact same molecules that it came from.

  7. pile of plastic trash
    Microbes

    This plastic-gobbling enzyme just got an upgrade

    Scientists tweaked a bacterial enzyme and made it more efficient in breaking down plastics found in polyester and plastic bottles.

  8. harbor seal

    Microscopic structures that scatter light to give color to the wings of modern butterflies and moths date back almost 200 million years.

  10. measles vaccine
    Health & Medicine

    50 years on, vaccines have eliminated measles from the Americas

    Thanks to high vaccination rates, measles has mostly disappeared from the Americas.

  11. nerve cells in hippocampi
    Neuroscience

    Human brains make new nerve cells — and lots of them — well into old age

    In humans, new neurons are still born in old brains, new research suggests.

  12. eggshell
    Materials Science

    Eggshell nanostructure protects a chick and helps it hatch

    The nanoscale structure of a chicken eggshell changes to fulfill different functions as the egg incubates.
