Space station could test 'spooky' entanglement over record distance

Mon, 04/08/2013 - 9:21pm
By Clara MoskowitzLiveScience"Spooky" quantum entanglement connects two particles so that actions performed on one reflect on the other.

But now physicists propose sending half ...

Monkeys' lip-smacking sounds hint at genesis of human speech

Mon, 04/08/2013 - 9:21pm
By Tanya LewisLiveScience The lip-smacking vocalizations gelada monkeys make are surprisingly similar to human speech, a new study finds.Many non-human primates demonstrate lip-smacking behavior, but geladas are the only ones known to make undulating sounds, known as "wobbles," at the same time. (The wobbling sounds a little like a human hum would sound if the volume were being turned on and o...

Critters evolve rapidly to cope with environmental change

Mon, 04/08/2013 - 9:09pm
Critters can evolve over just a handful of generations to survive whatever environmental maladies humans toss their way, from climate change to over fishing, suggests a new study. "That is the first take-home message, and it is a positive message," Thomas Cameron, a biologist at Umea University in Sweden, told NBC News as he explained his new findings reported Tuesday in the journal Ecology Letter...

Readings from NASA's Curiosity rover show how Mars is losing its air

Mon, 04/08/2013 - 7:31pm
Scientists say new readings from NASA's Curiosity rover have confirmed how Mars lost its once-thick atmosphere.The measurements from Curiosity's Sample Analysis at Mars instrument, or SAM, provide fresh support for the view that a high-velocity stream of electrically charged particles from the sun has been stripping off Mars' atmosphere from the top. Mars is more vulnerable to that kind of atmosph...

Infrared camera takes 3-D images from miles away

Mon, 04/08/2013 - 3:34pm
A powerful new imaging technique has been developed by Scottish researchers that can build a 3-D image of a person or object from thousands of feet away. It can detect a single photon hitting its sensor — but interestingly, it can't see your face.The imaging device fires a beam of light at a target and waits to see how much of it bounces back, and when, known as the "time of flight" method. The re...
