| More powerful supercomputers? New device could bring optical information processing Posted: 22 Dec 2011 12:20 PM PST Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.  |
| Chemists solve an 84-year-old theory on how molecules move energy after light absorption Posted: 22 Dec 2011 12:20 PM PST The same principle that causes figure skaters to spin faster as they draw their arms into their bodies has now been used by researchers to understand how molecules move energy around following the absorption of light. Scientists now demonstrate for the first time the effect is real and also suggests how scientists could use it to control and predict chemical reaction pathways in general.  |
| New technique makes it easier to etch semiconductors Posted: 22 Dec 2011 12:20 PM PST Creating semiconductor structures for high-end optoelectronic devices just got easier, thanks to new research. Scientists developed a method to chemically etch patterned arrays in the semiconductor gallium arsenide, used in solar cells, lasers and other optoelectronic devices. Unlike other wet methods, metal-assisted chemical etching works in one direction, from the top down, without damaging the surface like dry etching does.  |
| 'Nanoantennas' show promise in optical innovations Posted: 22 Dec 2011 11:24 AM PST Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, telecommunications and computers.  |
| Computer assisted design (CAD) for RNA Posted: 22 Dec 2011 11:24 AM PST Researchers have developed computer assisted design-type tools for engineering RNA components to control genetic expression in microbes. This holds enormous potential for microbial-based production of advanced biofuels, biodegradable plastics, therapeutic drugs and a host of other goods now derived from petrochemicals.  |
| New particle at Large Hadron Collider discovered by ATLAS Experiment Posted: 22 Dec 2011 07:29 AM PST Researchers have made the first clear observation of a new particle at the Large Hadron Collider. The particle, the chi b(3P), is a new way of combining a beauty quark and its antiquark so that they bind together. Like the more famous Higgs particle, the chi b(3P) is a boson. However, whereas the Higgs is not made up of smaller particles, the chi b(3P) combines two very heavy objects via the same 'strong force' which holds the atomic nucleus together.  |
| Traditional social networks fueled Twitter's spread Posted: 21 Dec 2011 07:58 AM PST Researchers who studied the growth of the newly hatched Twitter from 2006 to 2009 say the site's growth in the United States actually relied primarily on media attention and traditional social networks based on geographic proximity and socioeconomic similarity. In other words, at least during those early years, birds of a feather flocked -- and tweeted -- together.  |
| New material cools under pressure Posted: 21 Dec 2011 07:56 AM PST Researchers have identified a new material that exhibits an inverse barocaloric effect at room temperature, which means that it cools when pressure is applied, unlike most other materials.  |
| Advance made in light slowing techniques Posted: 21 Dec 2011 07:56 AM PST Scientists have made a significant advance in the field of light-slowing techniques applied to microwave photonics, which open the door to integrating multiple functionalities into optical chips in the short and medium term.  |
| Complex polymer rings with breathtaking nanoscale architecture revealed Posted: 21 Dec 2011 07:56 AM PST Scientists have uncovered how nature minimises energy costs in rings of liquids with an internal nanostructure made of two chemically discordant polymers joined with strong bonds, or di-blocks, deposited on a silicon surface, in a new article.  |
| Computer vision research: Do you see what I see? Posted: 21 Dec 2011 06:19 AM PST A question confronting neuroscientists and computer vision researchers alike is how objects can be identified by simply "looking" at an image. But teaching a computer to "know" what it's looking at is far harder. Scientists have now modeled human brain structure to develop better programming approaches for computer object identification.  |
