Quantum computing? Physicists’ new technique for cooling molecules may be a stepping stone to quantum computing

At the heart of next-generation computers may be a collection of ultracold molecules held at temperatures a mere fraction of a degree above absolute zero. By combining two traditional atomic cooling technologies, physicists have pioneered a new technique for bringing normally springy molecules to a frozen standstill. Their results may be an important stepping stone towards future quantum computing.

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 those limitations, but the components of such computers require semiconductors that can emit light. Now, new research has enabled “bulk” silicon to emit broad-spectrum, visible light for the first time, opening the possibility of using the element in devices that have both electronic and photonic components.

New type of solar structure cools buildings in full sunlight

Scientists have designed an entirely new form of cooling panel that works even when the sun is shining. Such a panel could vastly improve the daylight cooling of buildings, cars and other structures by radiating sunlight back into the chilly vacuum of space.

Researchers attach Lyme disease antibodies to nanotubes, paving way for diagnostic device

Existing Lyme disease tests assess the presence of antibodies, which take weeks to form after the initial infection and persist after the infection is gone. Now, a nanotechnology-inspired technique may lead to diagnostics that can detect the organism itself.

Nanofoams for better body armor, blast protection

Engineers are developing nanofoams that could be used to make better body armor; prevent traumatic brain injury and blast-related lung injuries in soldiers; and protect buildings from impacts and blasts. It’s the first time researchers are investigating the use of nanofoams for structural protection.
