| Artificial leaf: Solar-to-fuel roadmap developed for crystalline silicon Posted: 04 Mar 2013 06:15 PM PST A new analysis points the way to optimizing efficiency of an integrated system for harvesting sunlight to make storable fuel.  |
| Quantum realm: Forging new pathways to quantum devices Posted: 04 Mar 2013 12:18 PM PST Physicists are manipulating light on superconducting chips, and forging new pathways to building the quantum devices of the future -- including super-fast and powerful quantum computers.  |
| Vortex loops could untie knotty physics problems Posted: 04 Mar 2013 10:08 AM PST Physicists have succeeding in creating a vortex knot -- a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists.  |
| Working at the extreme edge of cosmic ice Posted: 04 Mar 2013 09:58 AM PST Behind locked doors, in a lab built like a bomb shelter, Perry Gerakines makes something ordinary yet truly alien: ice. This isn't the ice of snowflakes or ice cubes. No, this ice needs such intense cold and low pressure to form that the right conditions rarely, if ever, occur naturally on Earth. And when Gerakines makes the ice, he must keep the layer so microscopically thin it is dwarfed by a grain of pollen. These ultrathin layers turn out to be perfect for recreating some of the key chemistry that takes place in space.  |
| Cassini spies bright Venus from Saturn orbit Posted: 04 Mar 2013 09:53 AM PST A distant world gleaming in sunlight, Earth's twin planet, Venus, shines like a bright beacon in images taken by NASA's Cassini spacecraft in orbit around Saturn.  |
| In Greenland and Antarctic tests, Yeti helps conquer some 'abominable' polar hazards Posted: 04 Mar 2013 09:34 AM PST A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains.  |
| Fermat's Last Theorem and more can be proved more simply Posted: 04 Mar 2013 07:56 AM PST Mathematicians have shown Fermat's Last Theorem can be proved using only a small portion of Grothendieck's work. Specifically, the theorem can be justified using "finite order arithmetic."  |
