| Supernova remnant 1987A continues to reveal its secrets Posted: 01 Apr 2013 05:28 PM PDT A team of astronomers has succeeded in observing the death throws of a giant star in unprecedented detail. In February of 1987, astronomers observing the Large Magellanic Cloud, a nearby dwarf galaxy, noticed the sudden appearance of what looked like a new star. In fact they weren't watching the beginnings of a star but the end of one and the brightest supernova seen from Earth in the four centuries since the telescope was invented. By the next morning news of the discovery had spread across the globe and southern hemisphere stargazers began watching the aftermath of this enormous stellar explosion, known as a supernova. |
| Watching fluid flow at nanometer scales: Tiny nanowires can lift liquids as effectively as tubes Posted: 01 Apr 2013 09:15 AM PDT Imagine if you could drink a glass of water just by inserting a solid wire into it and sucking on it as though it were a soda straw. It turns out that if you were tiny enough, that method would work just fine -- and wouldn't even require the suction to start. New research has demonstrated for the first time that when inserted into a pool of liquid, nanowires naturally draw the liquid upward in a thin film that coats the surface of the wire. |
| After Newtown: A new use for a weapons-detecting radar? Posted: 01 Apr 2013 08:20 AM PDT In the aftermath of the Newtown school shooting, an engineering professor envisions a new use for a weapons-detecting radar system he's been developing for the past few years. |
| Quantum dot commands light: A solid state ultrafast logic gate on a photon Posted: 01 Apr 2013 06:26 AM PDT If you could peek at the inner workings of a computer processor you would see billions of transistors switching back and forth between two states. In optical communications, information from the switches can be encoded onto light, which then travels long distances through glass fiber. Researchers are working to harness the quantum nature of light and semiconductors to expand the capabilities of computers in remarkable ways. |
| New mathematical model shows how society becomes polarized Posted: 01 Apr 2013 06:07 AM PDT Engineering researchers have devised a mathematical model that helps demonstrate what's behind the growing rift in American society. |
