Now maybe LED lighting will take off in more than just traffic lights and gadgets.

Opening Up New Optical Communications Wavelengths via NICT Current optical communications schemes rely on a narrow 1.55 micron wavelength band of about 10 terahertz, a band in which optical signals can be well controlled and loss of signal/data is fairly low. But to open up optical networks to the high data load of the future, we need to open up the span of available wavelength.
If cells are the building blocks of life, transistors are the building blocks of the digital revolution. Without transistors, the technological wonders you use every day -- cell phones , computers , cars -- would be vastly different, if they existed at all. Before transistors, product engineers used vacuum tubes and electromechanical switches to complete electrical circuits .
Listening to lysozymes with one of the smallest transistors ever made Lysozyme Folding P.G. Collins/UC Irvine Wiretapping an enzyme and listening as it unfolds could shed new light on the way proteins work, allowing researchers to monitor structural changes over a longer period of time than was previously possible. To do it, scientists tethered a nanoscale transistor to a molecule found in human tears. Understanding how proteins fold is a key challenge in biology — making synthetic versions is about much more than their molecular contents.
The answer was 8 Quantum Computer Courtesy D-Wave Vancouver-based quantum computer maker D-Wave Systems is the kind of company that often gets mixed reviews--either kudos for working on the very edge of a new and potentially groundbreaking technology, or dismissal for not exactly delivering the kind of Earth-shattering technology that people were perhaps expecting. Regardless, today D-Wave is marking one in the win column after announcing that it has achieved the world’s largest quantum computation using 84 qubits. A quick quantum computing primer : qubits, or quantum bits, are the basic units of quantum information, comparable to (but quite different from) a classical bit.
Double-blinded by the light Entangled Qubits Clusters of entangled qubits allow remote quantum computing to be performed on a remote server, while keeping the contents and results hidden. EQUINOX GRAPHICS When quantum computers eventually reach larger scales , they’ll probably remain pretty precious resources, locked away in research institutions just like our classical supercomputers.
