Flexing fingers for micro-robotics: Berkeley Lab scientists create a powerful, microscale actuator
Researchers with Berkeley Lab and the University of California, Berkeley, have developed an elegant and powerful new microscale actuator that can flex like a tiny beckoning finger. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a human hair and are promising for microfluidics, drug delivery, and artificial muscles.

New technology allows scientists to capture and preserve cancer cells circulating in the bloodstream
Scientists from the RIKEN Advanced Science Institute in Japan and University of California Los Angeles report a new nanoscale Velcro-like device that captures and releases tumor cells that have broken away from primary tumors and are circulating in the bloodstream. This new nanotechnology could be used for cancer diagnosis and give insight into the mechanisms of how cancer spreads throughout the body.

UCLA engineers develop new energy-efficient computer memory using magnetic materials
By using electric voltage instead of a flowing electric current, researchers from UCLA's Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM.

Stretchable electronics
Electronic devices become smaller, lighter, faster and more powerful with each passing year. Currently, however, electronics such as cell phones, tablets, laptops, etc., are rigid. But what if they could be made bendable or stretchy? According to the University of Delaware's Bingqing Wei, stretchable electronics are the future of mobile electronics, leading giants such as IBM, Sony and Nokia to incorporate the technology into their products.

Nanocrystals not small enough to avoid defects
A team of researchers from Berkeley Lab and other institutes has shown that contrary to computer simulations, the tiny size of nanocrystals is no safeguard from defects. Studies at Berkeley Lab's Advanced Light Source show that dislocations can form in the finest of nanocrystals when stress is applied.

Novel NIST process is a low-cost route to ultrathin platinum films
A NIST research group has developed a relatively simple, fast and effective method of depositing uniform, ultrathin layers of platinum atoms on a surface. Platinum is a widely used industrial catalyst as well as a key component in microelectronics, so the discovery may have widespread application in the design and manufacture of platinum-based devices.

Reality check for DNA nanotechnology
Two major barriers to advancement of DNA nanotechnology beyond the research lab have been knocked down. This emerging technology employs DNA as a programmable building material for nanometer-scale structures. Many applications are envisioned, and researchers recently demonstrated synthetic membrane channels made from DNA. Until now, however, design processes were hobbled by a lack of feedback; assembly was slow and often of poor quality. Now, as reported in PNAS and Science, researchers have removed these obstacles.

Building better structural materials
When materials are stressed, they eventually change shape. Initially these changes are elastic, and reverse when the stress is relieved. When the material's strength is exceeded, the changes become permanent. This could result in the material breaking or shattering, but it could also re-shape the material, such as a hammer denting a piece of metal. Understanding this last group of changes is the focus of research from a team including Carnegie's Ho-kwang "Dave" Mao.

Got food allergies? Thanks to UCLA, you can test your meal on the spot using a cell phone
A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a lightweight device called the iTube, which attaches to a common cell phone to detect allergens in food samples. The iTube attachment uses the cell phone's built-in camera, along with an accompanying smart-phone application that runs a test with the same high level of sensitivity a laboratory would.

UT Arlington research team wins $1.35 million NSF robotics grant to develop smart skin applications
Imagine a human-like robot with skin and clothes embedded with sensors that could help machines better assist human owners. Such "smart" robots are part of a new $1.35 million National Science Foundation project led by Dan Popa, a UT Arlington associate professor of electrical engineering. Popa is leading a collaborative effort to advance robots and robotic devices, improve prosthetics and enable those devices to perform tasks that people can no longer do themselves.

World's smallest reaction chamber
The world's smallest reaction chamber, with a mixing volume measured in femtolitres (million billionths of a litre), can be used to study the kind of speedy, nanoscale biochemical reactions that take place inside individual cells. By combining two electrospray emitters, not only can such reactions occur but the resulting products can be determined by mass spectrometry.
