  1. Materials Science

    Nanowires made from silver are super stretchy

    When silver nanowires stretch slowly, atoms on their surface can spread to heal weak spots. The discovery could lead to more flexible electronics.

  2. Climate

    Cool Jobs: Head in the clouds

    What do a microbiologist, an atmospheric scientist and a materials engineer have in common? They’ve all got their heads in the clouds.

  3. Animals

    Frog’s gift of grab comes from saliva and squishy tissue

    What puts the grip in a frog’s high-speed strike? Quick-change saliva and a super-soft tongue, scientists find.

  4. Physics

    Explainer: How batteries and capacitors differ

    Both batteries and capacitors can power electronic devices. Each, however, has different properties which may provide benefits — or limitations.

  5. Computing

    LEDs offer new way to kill germs in water

    Growing ultraviolet-light-emitting diodes on thin, flexible sheets of metal holds promise for water disinfection and other applications.

  6. Materials Science

    3-D printers offer better way to make some magnets

    3-D printers produced magnets as strong as conventional ones with less material wasted.

  7. Chemistry

    New coating for metals could cut engine wear

    Scientists have developed a new coating for engine parts that could reduce friction and engine wear. One big benefit: Cars may require fewer oil changes.

  8. Tech

    ‘Smart’ sutures monitor healing

    Coatings added to the threads used to stitch up a wound let researchers use electrical signals to monitor a wound’s healing — even one covered by a bandage.

  9. Materials Science

    Beetles offer people lessons in moisture control

    Taking tricks from a beetle, researchers are designing surfaces that collect water from the air or resist frost buildup.

  10. Materials Science

    Nano medicines take aim at big diseases

    Nanomedicines are new treatments and tools that are taking aim at disease from the cellular level. Medicine’s next big thing could be very teeny tiny.

  11. Tech

    Clear, stretchy sensor could lead to wearable electronics

    Researchers have combined plastics and metal to make a transparent, stretchable sensor. It could soon find use in touchscreens, wearable electronics and more.

  12. Tech

    Concrete science

    Teen researchers are exploring ways to strengthen this building material, use it for safety purposes and use its discarded rubble.
