Single-pixel power: Scientists make 3-D images without a camera
Their system uses simple, cheap detectors which have just a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
Bright explosion on the Moon
For the past 8 years, NASA astronomers have been monitoring the Moon for signs of explosions caused by meteoroids hitting the lunar surface. "Lunar meteor showers" have turned out to be more common than anyone ...

South Africa's new radio telescope reveals giant outbursts from binary star system
(Phys.org) —An international team of astronomers have reported the first scientific results from the Karoo Array Telescope (KAT-7) in South Africa, the pathfinder radio telescope for the $3 billion global ...
Non-wetting fabric drains sweat
(Phys.org) —Waterproof fabrics that whisk away sweat could be the latest application of microfluidic technology developed by bioengineers at the University of California, Davis.
Allosaurus fed more like a falcon than a crocodile, new study finds
The mighty T. rex may have thrashed its massive head from side to side to dismember prey, but a new study shows that its smaller cousin Allosaurus was a more dexterous hunter and tugged at prey more like a m ...
Cracking the ice code
(Phys.org) —What happened the last time a vegetated Earth shifted from an extremely cold climate to desert-like conditions? And what does it tell us about climate change today?
Invasive crazy ants are displacing fire ants in areas throughout southeastern US
Invasive "crazy ants" are displacing fire ants in areas across the southeastern United States, according to researchers at The University of Texas at Austin. It's the latest in a history of ant invasions ...
NASA's asteroid sample return mission moves into development
(Phys.org) —NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.
Principles of locomotion in confined spaces could help fire ant-inspired robot teams work underground (w/ video)
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much-despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar ...
'Makers' 3-D print shapes created using new design tool, bare hands
(Phys.org) —A new design tool interprets hand gestures, enabling designers and artists to create and modify three-dimensional shapes using only their hands as a "natural user interface" instead of keyboard ...
Crickets' calling song hits the high notes
(Phys.org) —Research has detailed how acoustic communication has evolved within a unique species of cricket which exploits extremely high frequency harmonics to interact.
