New understanding of electromagnetism could enable 'antennas on a chip'
A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic ...
'Phonon tunneling' explains heat flow across nanometer-wide gaps, study finds
Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea ...
Scientists tame Schrodinger's cat for a new type of quantum computer
Physicists at the University of Sussex have tamed one of the most counterintuitive phenomena of modern science in their quest to develop a new generation of machines capable of revolutionizing the way we ...
NASA scientist offers perspective on the factors that may lead to life on a planet
Desolenator has tech for water independence, looks to 2015 (w/ Video)
Best of Last Week – Earth's invisible shield, a sound loud enough to bend light on a chip and toxic e-cigarettes
Tabletop experiment could detect gravitational waves
(Phys.org)—A coin-sized detector might observe gravitational waves before the giant Laser Interferometer Gravitational-Wave Observatory (LIGO), according to two Australian physicists.
A cool way to cool: Engineers invent high-tech mirror to beam heat away from buildings into space
Stanford engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space.
Star Trek-like invisible shield found thousands of miles above Earth
A team led by the University of Colorado Boulder has discovered an invisible shield some 7,200 miles above Earth that blocks so-called "killer electrons," which whip around the planet at near-light speed ...
Heat transfer sets the noise floor for ultrasensitive electronics
A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes ...
Researcher devises a new way to mimic Hawking radiation in a lab
Generating broadband terahertz radiation from a microplasma in air
Researchers at the University of Rochester's Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation.
Chemists create 'comb' that detects terahertz waves with extreme precision
Light can come in many frequencies, only a small fraction of which can be seen by humans. Between the invisible low-frequency radio waves used by cell phones and the high frequencies associated with infrared ...
Cosmologically complicating dust
The universe was created 13.7 billion years ago in a blaze of light: the big bang. Roughly 380,000 years later, after matter (mostly hydrogen) had cooled enough for neutral atoms to form, light was able to ...
