Squeezing light into metals
Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Colored diamonds are a superconductor's best friend
Nitrogen-vacancy centers -- flaws in a diamond's crystal lattice that produce color -- have received much attention for their sensitivity to magnetic fields. University of California Berkeley, University of California Los Angeles and Ben-Gurion researchers have now used N-V diamond sensors to detect the tiny magnetic fluctuations that occur on the surface of high-temperature superconductors in hopes of discovering how these much ballyhooed but still mysterious materials work. With their chip sensor, they hope to measure the properties of a single magnetic vortex.

Robotic prosthesis turns drummer into a 3-armed cyborg
Georgia Tech has created a robotic drumming prosthesis with motors that power two drumsticks. The first stick is controlled both physically by the musicians' arms and electronically using electromyography muscle sensors. The other stick 'listens' to the music being played and improvises. The robot that can be attached to amputees, allowing its technology to be embedded into humans.

A small step toward discovering habitable earths
For the first time, University of Arizona astronomers have used the same imaging technology found in a digital camera to take a picture of a planet far from our solar system with an Earth-based telescope. The accomplishment is a small step toward the technology astronomers will need in order to characterize planets suitable for harboring life.

First-ever 3-D image created of the structure beneath Sierra Negra volcano
The Galapagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved. Now research out of the University of Rochester is providing a better picture of the subterranean plumbing system that feeds the Galapagos volcanoes.

Darwin: It's not all sexual (selection)
Scientists have long considered bird song to be an exclusively male trait, resulting from sexual selection. Now an international team of researchers says that's not the whole story. In Nature Communications, they write that 71 percent of songbirds in their extensive global survey had female song, and trait mapping revealed a common ancestor of modern songbirds also had female song. This research opens the door to explore alternative processes in the evolution of bird song.

Pigment or bacteria? Researchers re-examine the idea of 'color' in fossil feathers
Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research from North Carolina State University demonstrates that it is not yet possible to tell if these structures -- thought to be melanosomes -- are what they seem, or if they are merely the remnants of ancient bacteria.

New fins evolve repeatedly in teleost fishes
Present in more than 6,000 living species of fish, the adipose fin, which lies between the dorsal fin and tail, has no clear function and is thought to be vestigial. However, a new study analyzing their origins finds that these fins arose repeatedly and independently in multiple species -- a striking example of convergent evolution. In addition, adipose fins appear to have repeatedly and independently evolved a skeleton, offering a glimpse the evolution of vertebrate appendages.

A single gene, doublesex, controls wing mimicry in butterflies
A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies, report scientists from the University of Chicago, March 5 in Nature. Surprisingly, the gene described, doublesex, is already well-known for its critical role in sexual differentiation in insects.

Brain circuits multitask to detect, discriminate the outside world
A new study found that neural circuits in the brain rapidly multitask between detecting and discriminating sensory input, such as car headlights in the distance. That's different from how electronic circuits work, where one circuit performs a very specific task. The brain, the study found, is wired in way that allows a single pathway to perform multiple tasks.

Cholesterol study suggests new diagnostic, treatment approach for prostate cancer
Researchers have discovered a link between prostate cancer aggressiveness and the accumulation of a compound produced when cholesterol is metabolized in cells, findings that could bring new diagnostic and treatment methods. Findings also suggest that a class of drugs previously developed to treat atherosclerosis might be repurposed for treatment of advanced prostate cancer.

New technique targets C code to spot, contain malware attacks
Researchers from North Carolina State University have developed a new tool to detect and contain malware that attempts root exploits in Android devices. The tool improves on previous techniques by targeting code written in the C programming language -- which is often used to create root exploit malware, whereas the bulk of Android applications are written in Java.
