NOvA neutrino detector records first 3-D particle tracks

(Phys.org) —What will soon be the most powerful neutrino detector in the United States has recorded its first three-dimensional images of particles.

Artificial muscle computer performs as a universal Turing machine

(Phys.org) —In 1936, Alan Turing showed that all computers are simply manifestations of an underlying logical architecture, no matter what materials they're made of. Although most of the computer's we're familiar with are made of silicon semiconductors, other computers have been made of DNA, light, legos, paper, and many other unconventional materials.

Scientists propose revolutionary laser system to produce the next LHC

An international team of physicists has proposed a revolutionary laser system, inspired by the telecommunications technology, to produce the next generation of particle accelerators, such as the Large Hadron Collider.

Georgia Students To Speak Live with Space Station Commander

Students and educators at Stratford Academy in Macon, Ga., will speak with Canadian Space Agency astronaut Chris Hadfield aboard the International Space Station on Wednesday, April 3, via amateur radio. Media are invited to attend at the school.

New Space Station Residents En Route to Orbiting Laboratory

Three new crew members are on an unprecedented fast track to the International Space Station, going from the launch pad to the orbiting complex in just six hours.

Better than X-rays: A more powerful terahertz imaging system

(Phys.org) —Low-energy terahertz radiation could potentially enable doctors to see deep into tissues without the damaging effects of X-rays, or allow security guards to identify chemicals in a package without opening it. But it's been difficult for engineers to make powerful enough systems to accomplish these promising applications.

Rare find backs shape-shifting neutrino

Physicists announced further proof Wednesday for a theory that mysterious particles called neutrinos which go "missing" on the journey from the Sun to Earth are in fact shape-shifting along the way, arriving undetected.

New technique for cooling molecules may be stepping stone to quantum computing

(Phys.org) —The next generation of computers promises far greater power and faster processing speeds than today's silicon-based based machines. These "quantum computers"—so called because they would harness the unique quantum mechanical properties of atomic particles—could draw their computing power from a collection of super-cooled molecules.

Imaging methodology reveals nano details not seen before: Understanding nanoparticles at atomic scale in 3-D could improve materials

Scientists have produced 3-D images and videos of a tiny platinum nanoparticle at atomic resolution that reveal new details of defects in nanomaterials that have not been seen before.

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.
