Physicists build quantum amplifier with single artificial atom
Fiber-wireless (Fi-Wi) to provide ultra-high-speed, short-range communication
MIT researchers build an all-optical transistor
Optical computing—using light rather than electricity to perform calculations—could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform ...
Hidden magma layer: Scientists discover 'lubricant' for Earth's tectonic plates
(Phys.org) —Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth's mantle that may be acting as a lubricant for the sliding motions of the ...
Radio Waves: Alternative Power Source
A new way to control information by mixing light and sound
For once, slower is better in a new piece of technology.
Engineer aims to connect the world with ant-sized radios
(Phys.org) —A Stanford engineering team has built a radio the size of an ant, a device so energy efficient that it gathers all the power it needs from the same electromagnetic waves that carry signals to ...
Low-power Wi-Fi signal tracks movement—even behind walls
The comic-book hero Superman uses his X-ray vision to spot bad guys lurking behind walls and other objects. Now we could all have X-ray vision, thanks to researchers at MIT's Computer Science and Artificial ...
Scientist closes in on a mystery that impedes space exploration
(Phys.org)—New research by Stanford aeronautics and astronautics Assistant Professor Sigrid Close suggests she's on track to solve a mystery that has long bedeviled space exploration: Why do satellites ...
At last, how many alien civilizations are there?
During the space age, 1961 was a special year: the Russian cosmonaut Yuri Gagarin became the first man to orbit Earth, while the American astronomer Frank Drake developed the now famous Drake Equation. This ...
Microsoft advocates new WiFi-NC to make use of white spaces in spectrum
Graphene may open the gate to future terahertz technologies
Nestled between radio waves and infrared light is the terahertz (THz) portion of the electromagnetic spectrum. By adding a nanoscale bit of graphene, researchers have found a better way to tune radiation for a THz transmitter.
Perfect communication with imperfect chips
One of the triumphs of the information age is the idea of error-correcting codes, which ensure that data carried by electromagnetic signals traveling through the air, or through cables or optical fibers ...
FAA warns pilots in Las Vegas vicinity on GPS
Pilots flying at night near Las Vegas over the next week may have to navigate the old-fashioned way - without GPS.
