Columbia engineers manipulate a buckyball by inserting a single water molecule
Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and drive motion of the "big" nonpolar ball through the encapsulated "small" polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. This method could lead to new applications including effective ways to control drug delivery and to assemble C60-based functional 3D structures at the nanoscale level.

National study of nanomaterial toxicity sets stage for policies to address health risks
For the first time, researchers from institutions around the country have conducted an identical series of toxicology tests evaluating lung-related health impacts associated with widely used engineered nanomaterials (ENMs). The study provides comparable health risk data from multiple labs, which should help regulators develop policies to protect workers and consumers who come into contact with ENMs.

Portable device provides rapid, accurate diagnosis of tuberculosis, other bacterial infections
A handheld diagnostic device that Massachusetts General Hospital investigators first developed to diagnose cancer has been adapted to rapidly diagnose tuberculosis and other important infectious bacteria. Two versions of the portable device combine microfluidic technology with nuclear magnetic resonance to not only diagnose these important infections but also determine the presence of antibiotic-resistant bacterial strains.

Microwave oven cooks up solar cell material
University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.

Robotic insects make first controlled flight
In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it leaped a few inches, hovered for a moment on fragile, flapping wings, and then sped along a preset route through the air. This demonstration of the first controlled flight of an insect-sized robot is the culmination of more than a decade's work, led by researchers at Harvard.

Shaking things up: NIST researchers propose new old way to purify carbon nanotubes
An old, somewhat passé, trick used to purify protein samples based on their affinity for water has found new fans at the National Institute of Standards and Technology, where materials scientists are using it to divvy up solutions of carbon nanotubes, separating the metallic nanotubes from semiconductors. They say it's a fast, easy and cheap way to produce high-purity samples of carbon nanotubes for use in nanoscale electronics and many other applications.

Bug's eye inspires hemispherical digital camera
Inspired by the complex fly eye, a University of Illinois at Urbana-Champaign and Northwestern University research team has developed a hemispherical digital camera with nearly 200 tiny lenses, delivering exceptionally wide-angle field of view and sharp images. The new camera -- a rounded half bubble, similar to a bulging fly eye -- has 180 microlenses mounted on it, allowing it to take pictures across nearly 180 degrees. Only a camera shaped like a bug's eye can do this.

Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

Battery and memory device in 1
Resistive memory cells are regarded as a promising solution for future generations of computer memories. Unlike the building blocks of conventional hard disk drives and memories, these novel memory cells are not purely passive components but must be regarded as tiny batteries. This has been demonstrated by researchers of Jülich Aachen Research Alliance, whose findings have now been published in the prestigious journal Nature Communications.

T2 Bio publishes data supporting diagnostic test T2Candida® in Science Translational Medicine
Deadly blood infections, or sepsis, are one of the top 10 causes of death in the United States. Each hour of delayed treatment increases the mortality of patients by 8%. This new diagnostic technology, T2Candida, achieved a 25X faster time to result, reducing the detection time of the fungus that can cause sepsis, Candida, from at best 48 hours to 3 hours. This research represents the first time Candida has been identified directly from whole blood in patient samples at clinically relevant levels.

What's old is new again
While automotive and medical device manufacturing may seem unrelated, the latter has benefited from the former. For example, manufacturing techniques developed for increasing the wear resistance of metallic camshafts are routinely used in hip implants. In both applications, performance and reliability are enhanced by increasing the strength of a metal part's surface. Now, an engineer in the Bourns College of Engineering at the University of California, Riverside seeks to extend this concept to medical devices.
