Powerful ancient explosions explain new class of supernovae Posted: 18 Dec 2013 10:38 AM PST Astronomers have discovered two of the brightest and most distant supernovae ever recorded, 10 billion light-years away and a hundred times more luminous than a normal supernova.

First battery-powered invisibility cloak designed Posted: 18 Dec 2013 10:03 AM PST Researchers have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.

Europe's billion-star surveyor is ready for launch Posted: 18 Dec 2013 10:02 AM PST Europe's billion-star surveyor, Gaia, is due to be launched into space on Thursday 19 December 2013, where it will embark on its mission to create a highly accurate 3D map of our galaxy.

3D technology from film industry improves rehab for stroke patients Posted: 18 Dec 2013 08:29 AM PST Researchers have been using 3D technology from the film industry to analyze the everyday movements of stroke patients. The results indicate that computerized motion analysis increases our knowledge of how stroke patients can improve their ability to move through rehabilitation.

3-D tissue printing: Cells from the eye inkjet-printed for the first time Posted: 18 Dec 2013 07:02 AM PST Scientists have used inkjet printing technology to successfully print cells taken from the eye for the very first time. The breakthrough could lead to the production of artificial tissue grafts made from the variety of cells found in the human retina and may aid in the search to cure blindness.

Computer-controlled table could direct radiotherapy to tumors while sparing vital organs Posted: 18 Dec 2013 07:02 AM PST Swivelling patients around on a computer-controlled, rotating table could deliver high doses of radiotherapy to tumors more quickly than current methods, while sparing vulnerable organs such as the heart, brain, eyes and bowel. Sophisticated computer modelling could be used to slowly move the table -- known as a couch -- and a radiation source in three dimensions to direct radiation precisely to the patient's tumor, researchers have suggested.

Algae to crude oil: Million-year natural process takes minutes in the lab Posted: 18 Dec 2013 07:01 AM PST Engineers have created a chemical system that continually produces useful crude oil minutes after they pour in raw algae material -- a green paste with the consistency of pea soup. The technology eliminates the need to dry the algae and recycles ingredients such as phosphorus, cutting costs. The work has been licensed to a biofuels company which is working with an industrial partner to build a pilot plant.

How hypergravity impacts electric arcs Posted: 18 Dec 2013 06:58 AM PST A new study on electric discharge behavior under intense gravitational forces shows that its dynamic changes as gravity increases. Arc discharges are common in everyday conditions like welding or in lightning storms. But in altered gravity, not as much is known about the behavior of electric discharges.
