Ultralow-power memory uses orders of magnitude less power than other devices
No-photon laser: Physicists demonstrate 'superradiant' laser design
Physicists at JILA have demonstrated a novel "superradiant" laser design, which has the potential to be 100 to 1,000 times more stable than the best conventional visible lasers. This type of laser could boost ...
Ferroelectric-graphene-based system could lead to improved information processing
Researchers at MIT have proposed a new system that combines ferroelectric materials—the kind often used for data storage—with graphene, a two-dimensional form of carbon known for its exceptional electronic ...
Smart skin: Electronics that stick and stretch like a temporary tattoo (w/ video)
Engineers have developed a device platform that combines electronic components for sensing, medical diagnostics, communications and human-machine interfaces, all on an ultrathin skin-like patch that mounts ...
IBM creates first graphene based integrated circuit
'Microrings' could nix wires for communications in homes, offices
(PhysOrg.com) -- Purdue University researchers have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for ...
NASA spacecraft records 'Earthsong'
Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.
Printable 'bionic' ear melds electronics and biology
Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability.
Metamaterials approach makes better satellite antennas
(PhysOrg.com) -- Cheaper, lighter and more energy-efficient broadband devices on communications satellites may be possible using metamaterials to modify horn antennas, according to engineers from Penn State ...
New electromechanical circuit sets record beating microscopic 'drum'
Described in the March 10 issue of Nature, the NIST experiments created strong interactions between microwave light oscillating 7.5 billion times per second and a "micro drum" vibrating at radio frequencies 11 mil ...
US military unveils non-lethal heat ray weapon
A sensation of unbearable, sudden heat seems to come out of nowhere -- this wave, a strong electromagnetic beam, is the latest non-lethal weapon unveiled by the US military this week.
Super-massive black hole inflates giant bubble
Like symbiotic species, a galaxy and its central black hole lead intimately connected lives. The details of this relationship still pose many puzzles for astronomers. Some black holes actively accrete matter. ...
