First Experimental Signs of a New Physics Beyond the Standard Model
July 31, 2013 — Physicists have predicted deviations in the probability of one of the B meson decays that have been detected experimentally in the LHC accelerator at CERN. Confirmation of these results would be the ... > full story -
Cause of LED 'Efficiency Droop' Identified
July 30, 2013 — Researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to ... > full story -
Beam Me Up, Scotty! Would Teleporting Humans Into Space Be Possible?
July 30, 2013 — In the science fiction show, Star Trek, teleportation is a regular and significant feature. But how much time and power is required to send the data needed to teleport a human ... > full story -
Tetrapod Nanocrystals Light the Way to Stronger Polymers
July 29, 2013 — Researchers have developed advanced opto-mechanical stress probes based on tetrapod quantum dots (tQDs) that allow precise measurement of the tensile strength of polymer fibers with minimal impact on ... > full story -
When Fluid Dynamics Mimic Quantum Mechanics
July 29, 2013 — Researchers expand the range of quantum behaviors that can be replicated in fluidic systems, offering a new perspective on wave-particle ... > full story -
Experimental Quest to Test Einstein's Speed Limit
July 29, 2013 — Special relativity states that the speed of light is the same in all frames of reference and that nothing can exceed that limit. UC Berkeley physicists used a novel experimental system -- the unusual ... > full story -
