Vagaries of real-world circuitry affect performance of promising new technique in signal processing and imaging
The last 10 years have seen a flurry of research on an emerging technology called compressed sensing. Compressed sensing does something that seems miraculous: It extracts more information from a signal than ...
Fuel cell park in Connecticut is on board for 2013
Mobile Internet forcing computers to evolve
The shift to smartphones and tablets became a landslide this year, crushing desire for laptop computers and pressuring manufacturers to adapt to the mobile Internet era.
Thorium: Proliferation warnings on nuclear 'wonder-fuel'
Thorium is being touted as an ideal fuel for a new generation of nuclear power plants, but in a piece in this week's Nature, researchers suggest it may not be as benign as portrayed.
Overclockers can celebrate Raspberry Pi turbo mode
Chips as mini Internets
Computer chips have stopped getting faster. In order to keep increasing chips computational power at the rate to which weve grown accustomed, chipmakers are instead giving them additional cores, or ...
How the alphabet of data processing is growing: Research team generates flying 'qubits'
The alphabet of data processing could include more elements than the "0" and "1" in future. An international research team has achieved a new kind of bit with single electrons, called quantum bits, or qubits. ...
Plant power: The ultimate way to 'go green'?
Researchers are turning to plants and solar power in the search for new sources of renewable and sustainable energy that can support the transition from rapidly depleting fossil fuels to a bio-based society. An article published ...
High-speed CMOS sensors provide better images
Conventional CMOS image sensors are not suitable for low-light applications such as fluorescence, since large pixels arranged in a matrix do not support high readout speeds. A new optoelectronic component ...
Why many cells are better than one
Researchers from Johns Hopkins have quantified the number of possible decisions that an individual cell can make after receiving a cue from its environment, and surprisingly, it's only two.
'Jaguar' supercomputer gaining speed
Cray Inc. said it has sealed a deal to overhaul the US Department of Energy's "Jaguar" supercomputer, making it faster than any other machine on the planet.
New parallelization technique boosts our ability to model biological systems
Researchers at North Carolina State University have developed a new technique for using multi-core chips more efficiently, significantly enhancing a computer's ability to build computer models of biological systems. The technique ...
