    Chemistry Nobel honors pioneers of world’s smallest machines

    Three chemists are being honored with a Nobel Prize for their pioneering work creating itty bitty machines, including a microscopic ‘nanocar.’

    Hot, hot, hot? New fabric could help you stay cool

    A plastic fabric can let body heat escape efficiently, if the material is filled with tiny bubbles of just the right size

    Why trans fats became a food villain

    Trans fats are now known as a dietary villain. But in the beginning, scientists thought they were better than butter.

  4. Plants

    Houseplants suck up air pollutants that can sicken people

    Certain indoor air pollutants can sicken people. But some houseplants can remove those chemicals from a room’s air, new data show.

  5. Tech

    One day, computers may decode your dreams

    Scientists are learning how to translate brain activity into words and thoughts. This may one day allow people to control devices with their minds.

  6. Brain

    Explainer: How to read brain activity

    Electricity underlies the chattering of brain cells. Here’s how scientists eavesdrop on those conversations.

    Nicotine from smoke enters body through the skin

    Scientists have shown for the first time that nicotine from cigarette smoke can enter the body through bare skin from the air or contact with smoky clothes.

  8. Computing

    Self-designed tattoos are fashionable technology

    Researchers have created do-it-yourself temporary tattoos. They’re a fashion-forward way to control electronic devices.

  9. Chemistry

    Lab creates new, unexpected type of ‘firenadoes’

    A newly discovered type of fiery vortex burns hot and generates little soot. Scientists suspect it could be a solution to cleaning up oil spills at sea.

  10. Genetics

    Explainer: What is epigenetics?

    Epigenetics is the study of molecular “switches” that turn genes on and off. Tweak those switches and there could be big health consequences.

  11. 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.

  12. 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.
