(Â鶹ÒùÔº) —Scientists are just beginning to discover and investigate materials that can change from insulators to conductors at room temperature under an applied voltage. There are only a few known examples, but their ...
(Â鶹ÒùÔº) —Tiny implants to monitor bodily functions or to provide insulin or any other drug based on immediate need would be an advancement in personalized medicine, but a problem inherent in implants is the tendency ...
(Â鶹ÒùÔº) —John Howell, a Professor of Â鶹ÒùÔºics at the University of Rochester, and his teenage son, have uploaded a paper to the preprint server arXiv in which they suggest that some common magicians' tricks could be used ...
(Â鶹ÒùÔº) —Researchers have demonstrated a method for "temporal cloaking" of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications.
The development of structured synthetic materials with unusual electromagnetic properties, so-called metamaterials, promises to provide access to special physical effects of great technological interest. Metamaterials have ...
By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A ...
(Â鶹ÒùÔº) —The new material's artificial "atoms" are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility cloaks.
Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.
In this month's issue of Â鶹ÒùÔºics World, an international group of researchers propose a new technology that could divert vibrations away from load-bearing elements of bridges to avoid catastrophic collapses.
(Â鶹ÒùÔº) —NASA's Cassini spacecraft has provided the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn's rings. These observations make Saturn's rings the only location ...
