     Here’s how to make a fiber-optic cable out of air using a laser

    A hollowed-out laser beam heats a tube of air that surrounds cooler air, providing a way to guide light much the way fiber optics do.

    Physics

     Tiny bubbles that make icicles hazy are filled with water, not air

    Like tree rings, layers of itty-bitty water pockets also preserve a record of an icicle’s growth.

    Jumping beans’ random strategy always leads to shade — eventually

    Jumping beans use randomness to maximize their chances of getting out of the sun’s heat, a new study finds.

     We could get messages back from spacecraft sent through a wormhole

    A simulation of a probe sent to the other side of a wormhole shows it could send speedy messages back before the hole closes and the probe is lost.

    Space

     Humans haven’t set foot on the moon in 50 years. That may soon change

    In 1972, the era of crewed missions to the moon came to an end. Fifty years later, a new one has begun.

    Physics

     In a breakthrough experiment, nuclear fusion finally makes more energy than it uses

    The sun creates energy through nuclear fusion. Now scientists have too, in a controlled lab experiment, raising hopes for developing clean energy.
