  1. Tech

    Technique puts more data into airwaves

    A new approach that exploits the orientations of the electric and magnetic fields in radio waves may increase data flows to and from cell phones and other wireless devices by up to a factor of six.

  2. Chemistry

    Cut-ups create soft spots for chemistry

    Networks of fabricated, squishy vesicles as tiny as red blood cells and connected by thin tubules may one day serve as microscopic chemical laboratories, sensors, and even chemical computers.

  3. Tech

    Current may flow free and cheap

    Wires that carry electricity without resistance at relatively high temperatures--and are inexpensive--moved a large step closer to reality as a 100-fold speed-up in depositing a key material wiped out a major obstacle to making those wires.

  4. Tech

    From silicon seeds, laser might sprout

    The achievement of light amplification in a layer of tiny nuggets of silicon called quantum dots raises the possibility that long-desired silicon lasers are on the way.

  5. Physics

    Heating, simulations get the drop on drips

    Air can buoy a layer of oil and, perhaps, even water leaking through a ceiling, if the air is relatively warm compared with the liquid.
