In a new approach to invisibility cloaking, a team of French researchers has proposed isolating or cloaking objects from sources of heatessentially "thermal cloaking." This method, which the researchers describe in the Optical Society's open-access journal Optics Express, taps into some of the same principles as optical cloaking and may lead to novel ways to control heat in electronics and, on an even larger scale, might someday prove useful for spacecraft and solar technologies.

Researchers have designed the first theoretical model that describes the occurrence of multiple solitary optical waves, referred to as dark photovoltaic spatial solitons. The findings by Yuhong Zhang, a physicist from the Xi'an Institute of Optics and Precision Mechanics of the Chinese Academy of Science, and his colleagues is about to be published in the European Physical Journal D

Optics and photonics may one day revolutionize computer technology with the promise of light-speed calculations. Storing light as memory, however, requires devices known as microresonators, an emerging technology that cannot yet meet the demands of computing. The solution, described in a paper published today in the Optical Society's (OSA) journal Optics Letters, may lie in combining light's eerie quantum properties with a previously unknown quality of optical fiber.

Researchers at Yale University are studying how two types of nanoscale structures on the feathers of birds produce brilliant and distinctive colors. The researchers are hoping that by borrowing these nanoscale tricks from nature they will be able to produce new types of lasersones that can assemble themselves by natural processes.

It's here, Apple's iPhone 5, or rather the iPhone 4S--ending a ton of speculation about its name, and spurring hundreds of "what, no iPhone 5?" comments from webizens who'd been hoping for that exciting-sounding re-design to surface. The thing is, though, the iPhone for 2011 is very similar in external design to the iPhone for 2010, but its real selling power is what's inside

Vanderbilt University engineers have created a "spongy" silicon biosensor that shows promise not only for medical diagnostics, but also for the detection of dangerous toxins and other tiny molecules in the environment. This innovation was originally designed to detect the presence of particular DNA sequences, which can be extremely helpful in identifying whether or not a person is predisposed to heart disease or certain kinds of cancer. The new sensor is described in the Optical Society's open access journal, Optics Express.
