- NewsOrdinarily in continuous motion, light pulses come to a dead stop in specially prepared atom clouds.
- FeaturePromising new ways to magnetically probe tissues and substances are emerging now that a small research group has proved their once-ridiculed claim of a flaw in the 50-year-old theory behind magnetic resonance imaging (MRI) and similar analytic techniques.
- NewsA 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.
- NewsNetworks 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.
- NewsWires 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.
- NewsThe 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.
- NewsAir can buoy a layer of oil and, perhaps, even water leaking through a ceiling, if the air is relatively warm compared with the liquid.
