  1. Tech

    Particles from tree waste could prevent fogged lenses, windshields

    A new coating made from a renewable resource — water-loving nanoparticles made from wood — could keep glass surfaces fog-free.

  2. Tech

    New glasses can ‘hear’ what you lip sync — and tell your phone

    The lip-reading device enables voice commands without the voice. The glasses determine what their wearer is saying by tracking facial movements.

  3. Tech

    Think of this new tech as sunglasses for our windows

    Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.

  4. Tech

    A tool as small as a human cell can scan for contaminants and more

    Tiny spectrometers might someday show up on smart devices. They could help people scan for ingredients or contaminants in foods and other materials.

  5. Tech

    You might someday ‘wallpaper’ your bedroom with this loudspeaker

    This thin, flexible and lightweight loudspeaker could reduce noise in loud spaces. It also might enable listeners to experience sound in new ways.

  6. Tech

    A new audio system confuses smart devices that try to eavesdrop

    It works by playing soft, calculated sounds to help people protect their privacy from automatic speech-recognition systems.

  7. Physics

    A new clock shows how gravity warps time — even over tiny distances

    This clock measured how gravity changes the passage of time in different places — even spots just one millimeter apart.

  8. Humans

    Explainer: How loud is too loud?

    Loud sounds, be it music or noise, might seem like no big deal at the time. But permanent damage can occur without noticeable warning signs.

  9. Tech

    This crumb-sized camera uses artificial intelligence to get big results

    Researchers have developed a camera the size of a coarse grain of salt that takes amazingly clear photos.

  10. Physics

    Future cars may offer personal sound zones — no earphones needed

    Zones that offer each passenger personal listening are closer to reality. A new design improves performance by adapting to the conditions in your car.
