2012 Football Helmet Ratings: Two More Added to the 5 Star Mark, Experts Say
May 1, 2012 — Virginia Tech released the results of its 2012 rating for adult football helmets that is designed to assess a helmet’s ability to reduce the risk of concussion.A total of three helmets achieved ... > full story -
Redefining Time: Extremely Precise Clock Signals Transmitted Over Long Distances
April 30, 2012 — Scientists have successfully sent a highly accurate clock signal across the many hundreds of kilometers of countryside that separate two ... > full story -
Single Nanomaterial Yields Many Laser Colors
April 29, 2012 — Engineers have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots ... > full story -
Atomic Clock Comparison Via Data Highways
April 27, 2012 — In the future, optical fibers could connect all optical atomic clocks within Europe -- a milestone for various users of optical frequencies in research and ... > full story -
Electron Politics: Physicists Probe Organization at the Quantum Level
April 25, 2012 — "Quantum critical points" (QCP) in exotic electronic materials can act much like polarizing "hot button issues" in an election. On either side of the QCP, electrons fall into line and behave as ... > full story -
Physicists Benchmark Quantum Simulator With Hundreds of Qubits
April 25, 2012 — Physicists have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits) -- 10 times more than previous devices. The simulator has passed a series of important ... > full story -
Can Future Actions Influence Past Events? Experiment Mimics Quantum Physics 'Spooky Action Into the Past'
April 23, 2012 — Physicists have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles ... > full story -
Atomic Blockade: Technique Efficiently Creates Single Photons for Quantum Information Processing
April 19, 2012 — Using lasers to excite just one atom from a cloud of ultra-cold rubidium gas, physicists have developed a new way to rapidly and efficiently create single photons for potential use in optical quantum ... > full story -
Raising the Prospects for Quantum Levitation
April 18, 2012 — An eerie quantum force may one day help separate the surfaces in tiny machines for frictionless movement. More than half-a-century ago, the Dutch theoretical physicist Hendrik Casimir calculated that ... > full story -
New Kind of Quantum Junction
April 18, 2012 — A new type of quantum bit called a "phase-slip qubit" has enabled the world's first-ever experimental demonstration of coherent quantum phase slip. The groundbreaking result sheds light on an elusive ... > full story
