Physical Review LettersMagnetic vortex antennas for wireless data transmission Three-dimensional magnetic vortices were discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf together with colleagues from the Paul Scherrer Institute within the scope of an international cooperation. The results were published in the scientific journal Physical Review Letters (DOI: 10.1103/PhysRevLett.110.177201). Vortex states are potential antennas for the ultrafast, wireless data transmission of tomorrow. Contact: Anja Weigl

Physical Review LettersColumbia 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.

Environmental Health PerspectivesNational 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.

Nature NanotechnologyPortable 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.

Journal of Crystal GrowthMicrowave 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. Contact: Lee J. Siegel

ScienceRobotic 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.

Journal of the American Chemical SocietyShaking 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. Contact: Michael Baum

NatureBug'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.
