    Nanowires could lead to super-long-lived battery

    Scientists have long been looking for ways to make rechargeable batteries that last forever. They now may be close. Their solution: gel-dipped nanowires.

  2. Animals

    Insects can patch their broken ‘bones’

    When insects suffer wounds, they can mend their ‘skeleton’ with a patch on the inside. This makes the leg strong again, new data show.

    How to make window ‘glass’ from wood

    Scientists have come up with a way to make wood transparent. The new material could be used in everything from windows to packaging.

  4. Physics

    Sunlight + gold = steaming water (no boiling needed)

    Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.

  5. Tech

    Eggshells help hatch a new idea for packaging

    Why just crack an egg? Make the shell into itty bitty bits and use them to build a more biodegradable plastic. New research shows how.

  6. Tech

    Goo-oozing deicer protects surfaces

    New, slime-oozing coating might someday help reduce ice and snow buildups on road signs and aircraft wings. The inspiration? The goo produced by slugs.

  7. Health & Medicine

    Flexible electronics track sweat

    A flexible, wireless health monitor that can wrap around the wrist tracks temperature and analyzes sweat to detect signs of too much water loss.

  8. Chemistry

    New bendy device could power wearable electronics

    A new device with lithium and silicon electrodes uses chemistry to generate electricity as it bends back and forth.

  9. Materials Science

    Wet suits with hair?

    The dense hair that keeps sea otters warm in frigid waters may inspire development of “furry” wet suits for scuba divers.

  10. Animals

    Some fish wear an invisibility cloak

    Some fish can hide in open water. How? Tiny crystals in their scales and skin help them reflect and blend in with polarized light.

    Explainer: Temperature and electrical resistance

    Higher temperatures mean more energy and more motion. In contrast, cold means slow moving molecules.

    Scientists Say: Kevlar

    Many people hear Kevlar and think of body armor. But this polymer is in so much more.
