  1. Venus flytrap grabbing a weight

    A robot arm toting a Venus flytrap can grab delicate objects

    By attaching electrodes to the plant’s leaves, researchers found a way to snap its traps shut on command.

  2. diabolical ironclad beetle

    The diabolical ironclad beetle can survive getting run over by a car. Here’s how

    The diabolical ironclad beetle is an incredibly tough little creature. A peek inside its exoskeleton reveals what makes it virtually uncrushable.

  3. two diamonds squeezing superconductor material

    The first room-temperature superconductor has finally been found

    A compound of carbon, hydrogen and sulfur conducts electricity without resistance up to 15° C, but there’s a catch: It works only under high pressure.

  4. sound wave

    Fundamental constants place a new speed limit on sound

    Physicists propose a new maximum rate that sound waves can travel under conditions normally found on Earth — 36 kilometers per second.

  5. illustration of a small, banded device in partial light and shadows

    A new device can produce electricity using shadows

    Even under low light, this new technology exploits the contrast between light and shade to produce a current that can power small electronics.

  6. a superconductor being squeezed between two diamonds

    50 years ago, superconductors started feeling the pressure

    Today, high-pressure superconductors are a hot topic. 50 years ago, scientists were just starting to explore the possibilities.

  7. Illustration of a hard edge

    A newfound superconducting current travels only along a material’s edge

    In a first, scientists spot electricity flowing without resistance on the rim of a topological superconductor.

  8. steak

    To cook a perfect steak, use math

    As a steak cooks in an oven, movement of liquid within the meat causes it to become extra juicy in the center in a way that can be predicted by mathematics.
