Perfect NCAA bracket? Near impossible: Mathematician says Posted: 02 Mar 2015 11:10 AM PST The odds of picking a perfect bracket for the NCAA men's basketball March Madness championship tournament are a staggering less than one in 9.2 quintillion (that's 9,223,372,036,854,775,808), according to a mathematics professor.

Important step towards quantum computing: Metals at atomic scale Posted: 02 Mar 2015 09:25 AM PST Scientists report that they could observe experimentally the current flow along channels at the crystal surfaces of topological insulators. The channels are less than one nanometer wide and extend along atomic steps of the crystal lattice. The scientists demonstrated also how these steps can be introduced in any arrangement.

Breakthrough in organic light emitting diodes technology Posted: 02 Mar 2015 09:24 AM PST Organic light emitting diodes (OLEDs), which are made from carbon-containing materials, have the potential to revolutionize future display technologies, making low-power displays so thin they'll wrap or fold around other structures, for instance.

Scientists trick the light fantastic Posted: 02 Mar 2015 07:52 AM PST What if one day, your computer, TV or smart phone could process data with light waves instead of an electrical current, making those devices faster, cheaper and more sustainable through less heat and power consumption? That's just one possibility that could one day result from an international research collaboration that's exploring how to improve the performance of plasmonic devices. The manipulation of light through tiny technology could lead to big benefits for everything from TVs to microscopes.

3-D printing offers innovative method to deliver medication Posted: 02 Mar 2015 04:13 AM PST 3-D printing could become a powerful tool in customizing interventional radiology treatments to individual patient needs, with clinicians having the ability to construct devices to a specific size and shape. Researchers and engineers collaborated to print catheters, stents and filaments to deliver antibiotics and chemotherapeutic medications to a targeted area in cell cultures.
