Two stopped light pulses interact with each other
Vertical cavity quantum switch could lead us away from electronics-based computing
Popular origami pattern makes the mechanical switch
An origami paper-folding pattern called the square twist is the basis of a microscopic switch that Cornell physicists say could lead to origami-inspired materials and machines.
Squeezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical engineering graduate ...
Black hole on a diet creates a 'changing look' quasar
Yale University astronomers have identified the first "changing look" quasar, a gleaming object in deep space that appears to have its own dimmer switch.
Researchers publish theory, formula to improve 'plastic' semiconductors
Anyone who's stuffed a smart phone in their back pocket would appreciate the convenience of electronic devices that could bend. Flexible electronics could spawn new products: clothing wired to cool or heat, ...
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 ...
All-optical magnetic switching promises terahertz-speed hard drive and RAM memory
(Phys.org) —Researchers at the Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used ...
Engineers enable 'bulk' silicon to emit visible light for the first time
Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass ...
Smallest, fastest-known RNA switches provide new drug targets
(Phys.org)—A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say ...
Reversible doping: Hydrogen flips switch on vanadium oxide
If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks ...
Engineers at Yale develop new type of mechanical memory
Single molecule can shift the phase of a laser beam
Before animals first walked on land, fish carried gene program for limbs
Genetic instructions for developing limbs and digits were present in primitive fish millions of years before their descendants first crawled on to land, researchers have discovered.
