In a new approach to invisibility cloaking, a team of French researchers has proposed isolating or cloaking objects from sources of heat—essentially "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.

Roadside bombs are often responsible for what's been called the "signature wound" for troops on the battlefield: brain injuries. Clarissa Ward visited the Concussion Care Center at Forward Operating Base Fenti in Afghanistan, where specialists there are taking a new approach to helping the wounded

(PhysOrg.com) -- Computer scientists at UC San Diego, who set out to simulate all rainbows found in nature, wound up answering questions about the physics of rainbows as well. The scientists recreated a wide variety of rainbows – primary rainbows, secondary rainbows, redbows that form at sunset and cloudbows that form on foggy days – by using an improved method for simulating how light interacts with water drops of various shapes and sizes.

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health.

(PhysOrg.com) -- Just when it began to appear that scientists had found a viable way around the problem of the blurring that occurs when using masks to create smaller and smaller silicon wafers for computer chips, a previous study on beam splitting optics showed that the new approach would not work, at least as it has thus far been proposed. A group of researchers explain why in a paper in New Journal of Physics.

Researchers at MIT have succeeded in making a fine thread that functions as a diode, a device at the heart of modern electronics. This feat — made possible by a new approach to a type of fiber manufacturing known as fiber drawing — could open up possibilities for fabricating a wide variety of electronic and photonic devices within composite fibers, using a variety of materials.

Exotic entities that arrange into a crystalline structure at near room-temperature could lead to a new approach to electronic memory.
