Double Crystal Fusion could pave the way for portable device
Researchers at Rensselaer Polytechnic Institute have developed a tabletop accelerator that produces nuclear fusion at room temperature, providing confirmation of an earlier experiment conducted at the University of California, Los Angeles (UCLA), while offering substantial improvements over the original design.
Reversible microlenses to speed chemical detection
Scientists at Georgia Tech have created technology capable of detecting trace amounts of biological or chemical agents in a matter of seconds, much faster than traditional methods, which can take hours or up to a day. The system uses reusable hydrogel microlenses so small that millions of them can fit on a one-inch-square plate. It could greatly enhance the ability of authorities responding to a biological or chemical weapons attack as well as increase the speed of medical testing.
Researchers think small to find safer alloys
MIT researchers have devised a new method for shrinking the size of crystals to make safer metal alloys. The new materials could replace metal coatings such as chromium, which is dangerous for factory workers to produce.
Method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes.
Mit powers up new battery for hybrid cars
Researchers at MIT have developed a new type of lithium battery that could become a cheaper alternative to the batteries that now power hybrid electric cars.
Fighting sound with sound
Newly published research by a Princeton engineer suggests that understanding how air travels across the sunroof of a car may one day make jet engines less noisy.
Scientists develop better method for converting sounds to electronic signals
Inspired by the way sound is processed in the brain, researchers at Carnegie Mellon University (CMU) have devised a new, highly efficient scheme for converting sounds to digital form. The payoff could be a significant improvement in the sound quality of cochlear implants, digital audio players, cellular telephones and many other devices.
Fingerprint advances will fight cybercrime
Forgot your password? No problem. Biometrics researchers at the University at Buffalo have made important advances that bring closer the day when we can access devices and Web sites with nothing more than the touch of a fingertip.
Quantum computer solves problem, without running
By combining quantum computation and quantum interrogation, scientists at the University of Illinois at Urbana-Champaign have found an exotic way of determining an answer to an algorithm - without ever running the algorithm.
New active cookie helps protect Internet users from cyber crooks
A new technique developed by an Indiana University School of Informatics scientist provides a strong shield against identity theft and cyber attacks.

Scientists study liquid nanodrops
Scientists from the U.S. Department of Energy's Brookhaven National Laboratory have discovered that drops of liquid with thicknesses of just a few billionths of a meter, or nanometers, are shaped differently than macroscopic liquid drops.
New material means X-Ray specs no longer required
A new optical effect has been created in a London laboratory that means solid objects such as walls could one day be rendered transparent, scientists report today in the journal Nature Materials.
Quantum breakup is no heartbreaker
Getting together and breaking up is hard to do, but splitting a quantum couple is even more difficult.
Lower cost, portable surgical robots could be smooth operators
A mechanical engineer at Purdue University is teaming up with medical doctors in research aimed at developing less expensive, portable and versatile surgical robots that could become more common in operating rooms.
Researchers find cell phones pose greater risk to airplane navigation than previously believed
A study by Carnegie Mellon University researchers in the Department of Engineering and Public Policy (EPP) has found that cell phones and other portable electronic devices, like laptops and game-playing devices, can pose dangers to the normal operation of critical electronics on airplanes. The study will be featured in an article appearing in the March issue of IEEE Spectrum.
Engineers pioneer forensics technology to catch cyber thieves
Researchers at the University of Maryland's A. James Clark School of Engineering are creating new digital fingerprinting technology that could help protect Hollywood's assets and identify national security leak sources, all without impinging on legitimate uses.
Are thougher electronic components on the way?
Like modern day alchemists, materials scientists often turn unassuming substances into desirable ones. But instead of working metal into gold, they create strange new compounds that could make the electronic components of the future smaller, faster, and more durable.
Nanoparticles create biocompatible capsules
An innovative strategy of mixing lipids and nanoparticles to produce new drug and agricultural materials and delivery vehicles has been developed by researchers at the University of Illinois at Urbana-Champaign.
Nano skins show promise as flexible electronic devices
A team of researchers has developed a new process to make flexible, conducting "nano skins" for a variety of applications, from electronic paper to sensors for detecting chemical and biological agents. The materials, which are described in the March issue of the journal Nano Letters, combine the strength and conductivity of carbon nanotubes with the flexibility of traditional polymers.
USC, rice to develop bacteria-powered fuel cells
A diverse team of microbiologists, engineers and geochemists from the University of Southern California and Rice University are joining forces to create bacteria-powered fuel cells that could power spy drones that fit in the palm of a hand.
