Physicists describe how to make time-reversed light pulses PhysOrg Share    
By taking advantage of the properties of periodic systems, physicists have calculated how to efficiently time-reverse ultrashort electromagnetic pulses. Read the associated Physical Review Letters abstract. More
Nanoantennas target single particles Physics World Share
Researchers have, for the first time, used a single nanoantenna to detect particles and atoms. The work could be used to make extremely sensitive gas sensors and detectors. More Material could facilitate wireless recharging U.S. News and World Report Share
Unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires. Read the associated Physical Review B abstract. More
Shrinking device makes objects appear smaller than they are PhysOrg Share
By controlling how light bends around an object, researchers have built a shrinking device that makes objects appear smaller than they actually are. Although the original object does not actually shrink, the illusion of the smaller object is convincing enough to confuse viewers since the real size of the object cannot be perceived. More Gators go a-courtin' with fancy physics Science News Share
Alligators flirt with physics. When males attract attention by quivering their spiky backs underwater, they create Faraday waves, researchers reported May 23 in Seattle at a meeting of the Acoustical Society of America. These sophisticated patterns are usually seen only in man-made devices. More
Semiconductor shows its chameleon side Physics World Share
Physicists in Japan have shown how to make a semiconductor magnetic simply by applying a fairly modest voltage across the material at room temperature. Although the effect had been seen before, it previously required ultralow temperatures and massive voltages. More Chu hopes kids will encourage families to go green NPR Share
Energy Secretary Steven Chu is launching an initiative to educate students about energy efficiency. More
Electron's shape revealed BBC News Share
The most accurate measurement yet of the shape of the electron has shown it to be almost perfectly spherical. The discovery is important because it may make some of the emerging theories of particle physics - such as supersymmetry - less likely. More
Stellar oddballs Science News Share
The Kepler space telescope is dedicated to hunting for earth-like planets, but has gathered far more data on a wide variety of other objects than astronomers working on the project can analyze. The Kepler team now hopes that outside astronomers will help study strange stars in the craft's data. More |
