Neutrinos Detected at Faster Than Light Speed
Source: CERN Posted: 9/23/11 The OPERA result is based on the observation of over 15000 neutrino events and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit.
Smarter robot arms
Source: MIT Posted: 9/22/11 A combination of two algorithms developed at MIT allows autonomous robots to execute tasks much more efficiently — and move more predictably.
Shake, rattle and … power up?
Source: MIT Posted: 9/18/11 Researchers at MIT have designed a device the size of a U.S. quarter that harvests energy from low-frequency vibrations, such as those that might be felt along a pipeline or bridge.
Quantum computing with light
Source: MIT Posted: 9/9/11 A switch that lets one photon alter the quantum state of another could point the way to both practical quantum computers and a quantum Internet.
'I beseech you to take interest in these sacred domains so expressively called laboratories. Ask that there be more and that they be adorned for these are the temples of the future, wealth and well-being. It is here that humanity will grow, strengthen and improve.
