| Advanced light: Sending entangled beams through fast-light materials Posted: 25 May 2014 12:53 PM PDT Whole beams, not just particles, can be entangled. This, plus anomalous dispersion in 'fast-light' materials, allows signals be to 'advanced' over signals travelling in vacuum, at least in a limited sense. |
| A new way to make sheets of graphene Posted: 23 May 2014 11:53 AM PDT Graphene's promise as a material for new kinds of electronic devices, among other uses, has led researchers around the world to study the material in search of new applications. But one of the biggest limitations to wider use of the strong, lightweight, highly conductive material has been the hurdle of fabrication on an industrial scale. |
| Social marketing at the movies Posted: 23 May 2014 11:53 AM PDT Word-of-mouth marketing is recognized as a powerful route from long-tail sales to blockbuster, whether one is talking about the latest fishy ice cream flavor or a Hollywood romantic comedy. In the age of social media and online networking sites, such as Twitter and Facebook, the potential for spreading the word could mean the difference between consumers seeing a product as the best thing since sliced bread or the most rotten of tomatoes. |
| Flatland optics with graphene: Smaller and faster photonic devices and circuits Posted: 23 May 2014 06:42 AM PDT Researchers have introduced a platform technology based on optical antennas for trapping and controlling light with the one-atom-thick material graphene. The experiments show that the dramatically squeezed graphene-guided light can be focused and bent, following the fundamental principles of conventional optics. The work opens new opportunities for smaller and faster photonic devices and circuits. |
| Chip produces and detects specialized gas for biomedical analysis Posted: 22 May 2014 09:35 AM PDT A chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging has been built and demonstrated. The new microfluidic chip produces magnetized xenon gas and then detects even the faintest magnetic signals from the gas. Magnetized xenon can be used as a marker for detecting biomolecules in liquids. Conventional systems for producing and using this gas can be as big as a car. |
| NCNR neutrons highlight possible battery candidate Posted: 22 May 2014 09:35 AM PDT Analysis of a manganese-based crystal has produced the first clear picture of its molecular structure. The findings could help explain the magnetic and electronic behavior of the whole family of crystals, many of which have potential for use in batteries. |
| Posted: 22 May 2014 08:58 AM PDT Researchers have found that a particular species of quantum dots that weren't commonly thought to blink, do. So what? Well, although the blinks are very short -- nanoseconds to milliseconds -- even brief fluctuations like these could signal trouble for using quantum dots in a quantum computer or between nodes of a future quantum Internet. |
| Posted: 21 May 2014 01:27 PM PDT It's that time of the year again when people are moving their kitchens outside in order to soak up the warm weather and smoky aromas of grilling. Researchers provide insight into the food science behind BBQ, and address how a marinade works to keep your meat tender, how smoking can infuses new flavors into meat, searing and more. |
| Posted: 21 May 2014 10:36 AM PDT Researchers have discovered a new way of harnessing temperature gradients in fluids to propel objects. In the natural world, the mechanism may influence the motion of icebergs floating on the sea and rocks moving through subterranean magma chambers. |
