    Trees may become the key to ‘greener’ foam products

    Scientists have made an environmentally friendly alternative to plastic-based foams to help keep things cool.

  2. Physics

    Dry sand can bubble like the blobs in a lava lamp

    Put two types of sand grains together in a chamber and they can flow like fluids. All it takes is a jiggle and some gas.

    Analyze This: Do exotic woods make better guitars?

    When comparing the sound of guitars made from rare and costly woods to those made with common, cheaper alternatives, guitarists couldn’t tell much of a difference.

    Shape-shifting chemical is key to new solar battery

    Storing solar energy is a challenge. A new, shape-shifting molecule may provide a solution.

  5. Physics

    How to turn a greenhouse into a powerhouse

    See-through solar cells could turn greenhouses into solar power plants.

    A self-cleaning glass keeps itself spotless underwater

    Microscopic pancake-like structures keep dirt and oil from sticking to the surface of this self-cleaning glass.

    Scientists Say: Zirconium

    Zirconium is a metal that knows the meaning of tough. It’s so heat resistant that it’s used for molds to shape melted metals, and so radiation resistant that it coats nuclear reactors.

  8. Materials Science

    This bandage uses electrical zaps to heal wounds faster

    Scientists have invented a bandage that helps wounds heal faster by zapping them with electricity. The patient’s own motions power this device.

    This rewritable paper depends on disappearing ink

    Scientists have made a new rewritable paper that can hold text and images for at least six months. It also can be reused more than 100 times.

  10. Materials Science

    Some plastics learn to repair themselves

    A new material can fix its own scratches and small cracks. One day, it also may make self-healing paints and plastics possible.

    Super-water-repellent surfaces can generate energy

    Scientists knew they could get power by running salt water over an electrically charged surface. But making that surface super-water-repellent boosts that energy production, new data show.

  12. Tech

    Soft robots get their power from the skin they’re in

    A flexible electronic “skin” embedded with air pouches or coils can wrap around inanimate objects, turning them into handy robots.
