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.
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.
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.
No longer just a diagnostic tool, ultrasound tackles surgery.
