Nature has produced exquisite composite materials--wood, bone, teeth, and shells, for example--that combine light weight and density with desirable mechanical properties such as stiffness, strength and damage tolerance. Since ancient civilizations first combined straw and mud to form bricks, people...
Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up. Using...
Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into two-dimensional atomic sheets for memory storage has failed to uncover their potential -- until now. A team of electrical...
JILA's three-dimensional (3-D) quantum gas atomic clock consists of a grid of light formed by three pairs of laser beams. Multiple lasers of various colors are used to cool the atoms, trap them in a grid of light, and...

A new DNA testing technique can accurately confirm relatedness between two individuals as distant as second cousins. With more DNA datasets at hand, the method could be utilized to identify disaster victims in mass floods and tornadoes that destroy...
“There’s a close correspondence between what you need for communication in rapidly changing networks and information processing in the brain,” professor Nancy Lynch says. “We’re trying to find problems that can benefit from this distributed-computing perspective, focusing on algorithms...
