MIT researchers from the Distributed Robotics Laboratory are working on the very first steps towards nano-bot technology. In their “Smart Sand” project, the researches hope to make tiny, sand-grain-sized, self-contained computers that can duplicate any object. One day, the researchers imagine that you will be able to deposit an object into a box of sand-grain-sized…
Watching a beautiful ballet can move viewers in more ways than one, according to a recent study in PLoS One. When spectators watched dance, especially a type with which they were familiar, they put themselves in the place of the dancer, their brains showing activity similar to what researchers would expect to see in dancers….
The Environmental Protection Agency and the White House Office of Information and Regulatory Affairs, which reviews all proposed federal regulations, have never used job figures as part of the calculus of the costs and benefits of rule-making, largely because there is no accepted methodology for assessing them. But the Institute for Policy Integrity at New…
Among its more dubious claims to fame, Tennessee was the site of the 1925 “Monkey Trial,” in which John Scopes was convicted of violating a state law against teaching that “man has descended from a lower order of animals.” Eighty-seven years later, the Tennessee Legislature is itching for an encore. It has sent to Gov….
Galaxy measurements indicate dark energy, not flaw in relativity, to blame for cosmic repulsion
Can a few neurons trigger a full memory? In a new study, published in Nature, a group of researchers from MIT showed for the first time that it is possible to activate a memory on demand, by stimulating only a few neurons with light, using a technique known as optogenetics. Optogenetics is a powerful technology…
The universe is filled with high-energy radiation, much of which is made of gamma rays belched out by strange pulsing stars and the remnants of supernova explosions. But a new study of some of most extreme objects has turned up a mystery: nearly one-third of all gamma-ray emitting objects seen to date defy identification. The…
Unthinkable as it may be, humanity, every last person, could someday be wiped from the face of the Earth. We have learned to worry about asteroids and supervolcanoes, but the more-likely scenario, according to Nick Bostrom, a professor of philosophy at Oxford, is that we humans will destroy ourselves. Bostrom, who directs Oxford’s Future of…
Why do some persons succumb to post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? UCLA scientists have linked two genes involved in serotonin production to a higher risk of developing PTSD. Published in the online edition of the Journal of Affective Disorders, the findings suggest that susceptibility to PTSD is…
Astronomers have measured the precise distance to over a quarter of a million galaxies to gain new insights into a key period in cosmic history. The 3D map of the sky allows scientists to probe the time six billion years ago when dark energy became the dominant influence on the Universe’s expansion. No-one knows the…
