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 ...
Device physics: Simulating electronic smog
A research team from A*STAR and Samsung Electronics has developed a fast and accurate way to estimate the electromagnetic emissions from printed circuit boards that could help designers to ensure that devices ...
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 ...
Laser guided codes advance single pixel terahertz imaging
The universe is awash in terahertz (THz) waves, as harmless as they are abundant. But unlike other regions of the electromagnetic spectrum, THz has proven to be extremely difficult to manipulate in order ...
FAA moving toward easing electronic device use
The U.S. government is moving toward easing restrictions on airline passengers using electronic devices to listen to music, play games, read books, watch movies and work during taxiing, takeoffs and landings.
First entanglement between light and optical atomic coherence
Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of ...
Magnetic materials that change their properties when heated could pack more data onto hard drives
A 'sandwich' of three iron alloy layers could help to create computer hard drives that can store more data than ever before. Tiejun Zhou and co-workers at the A*STAR Data Storage Institute in Singapore expect ...
Scientists moving 15-ton magnet from NY to Chicago
A 50-foot-wide electromagnet built in suburban New York is headed on a five-week journey to Chicago.
Massive particle storage ring to begin 3,200-mile trek on Sunday
(Phys.org) —How do you move a 50-foot-wide, circular electromagnet from Long Island to the Chicago suburbs in one piece without flexing or twisting it? Very, very carefully.
On a different wavelength: Scientists set out to create 'superspectral' camera
A team of engineers is setting out to create the world's first camera sensor capable of 'seeing' across a wide range of wavelengths.
Simple theory may explain dark matter
Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole.
NASA builds sophisticated Earth-observing microwave radiometer
(Phys.org) —A NASA team delivered in May a sophisticated microwave radiometer specifically designed to overcome the pitfalls that have plagued similar Earth-observing instruments in the past.
Specifically sized gold nanoparticle spheres increase sensitivity of light-based chemical detector
A sensor that relies on reflected light to analyze biomedical and chemical samples now has greater sensitivity, thanks to a carpet of gold nanoparticles. Xia Yu of the A*STAR Singapore Institute of Manufacturing ...
Organic chemistry: Leading light waves astray
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 ...
