| Quantum computer components 'coalesce' to 'converse' Posted: 26 Oct 2011 01:27 PM PDT A team of physicists has shown for the first time how very different types of photons can be made to share "quantum state" information. Such unlike photon links are likely to be an important feature of future quantum computers, where different types of components will need to share information with one another, just like the memory and logic circuits in today's computers.  |
| Posted: 26 Oct 2011 11:38 AM PDT Astronomers have measured the diameter of the dwarf planet Eris by catching it as it passed in front of a faint star. This was seen by telescopes in Chile, including the TRAPPIST telescope at the European Southern Observatory's La Silla Observatory. The observations show that Eris is an almost perfect twin of Pluto in size and appears to be covered in a layer of ice.  |
| Posted: 26 Oct 2011 11:37 AM PDT The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes, according to new tests. Both technologies pass electrical current through material to generate light, but the simpler LED emits lights only through spontaneous emission. Diode lasers bounce light back and forth internally before releasing it.  |
| Astronomers discover complex organic matter exists throughout the universe Posted: 26 Oct 2011 11:37 AM PDT Researchers from Hong Kong report that organic compounds of unexpected complexity exist throughout the Universe. They indicate that an organic substance commonly found throughout the Universe contains a mixture of aromatic and aliphatic components. The results suggest that complex organic compounds are not the sole domain of life but can be made naturally by stars.  |
| 'Magnetic tongue' ready to help produce tastier processed foods Posted: 26 Oct 2011 09:24 AM PDT The "electronic nose," which detects odors, has a companion among emerging futuristic "e-sensing" devices intended to replace abilities that once were strictly human-and-animal-only. It is a "magnetic tongue" -- a method used to "taste" food and identify ingredients that people describe as sweet, bitter, sour, etc. Scientists report on use of the method to taste canned tomatoes.  |
| Posted: 26 Oct 2011 07:31 AM PDT New research shows how metal surfaces that lack mirror symmetry could provide a novel approach towards manufacturing pharmaceuticals.  |
