Environmental Science and Technology
Worms lead way to test nanoparticle toxicity
Rice University scientists use roundworm populations in low-cost, high-throughput toxicity tests for a range of nanoparticles. The tests could cut the cost of determining which nanoparticles should be studied further for applications and for their effects on the environment.

Dance of the nanovortices
It is a familiar phenomenon: if a spinning top is set in rotation on an inclined surface, it scribes a series of small arches. Researchers at Berlin and Mainz together with research teams from the Netherlands and Switzerland have now succeeded in capturing this pattern of movement in a magnetic thin film system -- in the form of small magnetic nanovortices. The researchers made a new discovery: the nanovortices possess mass.

New method allows for greater variation in band gap tunability
By manipulating the ordered arrangement of atoms in layered complex oxide materials, Northwestern University's James Rondinelli has found a way to control their electronic band gaps, which determines the electrical behavior of the material and how it interacts with light.

DNA nanoswitches reveal how life's molecules connect
'Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,' said Wyss Associate Faculty member Wesley P. Wong, Ph.D., senior author of study. 'Rather than develop a new instrument, we've created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.'

Crystal light: New light-converting materials point to cheaper, more efficient solar power
Engineers have shone new light on an emerging family of solar-absorbing materials that could clear the way for cheaper and more efficient solar panels and LEDs. The materials, called perovskites, are particularly good at absorbing visible light, but had never been thoroughly studied in their purest form: as perfect single crystals. Using a new technique, researchers grew large, pure perovskite crystals and studied how electrons move through the material as light is converted to electricity.

Made-in-Singapore rapid test kit detects dengue antibodies from saliva
Finding out whether you have been infected with dengue may soon be as easy as spitting into a rapid test kit. The Institute of Bioengineering and Nanotechnology of A*STAR has developed a paper-based disposable device that will allow dengue-specific antibodies to be detected easily from saliva within 20 minutes. This device is currently undergoing further development for commercialization.

Nanoscale mirrored cavities amplify, connect quantum memories
Constructing tiny 'mirrors' to trap light increases the efficiency with which photons can pick up and transmit information about electronic spin states -- which is essential for scaling up quantum memories for functional quantum computing systems and networks.

Researchers use sound to slow down, speed up, and block light
Researchers from the University of Illinois at Urbana-Champaign have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed. This non-reciprocal behavior is essential for building isolators and circulators.

Stomach acid-powered micromotors get their first test in a living animal
Researchers at the University of California, San Diego have shown that a micromotor fueled by stomach acid can take a bubble-powered ride inside a mouse. These tiny motors, each about one-fifth the width of a human hair, may someday offer a safer and more efficient way to deliver drugs or diagnose tumors. The experiment is the first to show that these micromotors can operate safely in a living animal.

Carbon nanoballs can greatly contribute to sustainable energy supply
Researchers at Chalmers University of Technology have discovered that the insulation plastic used in high-voltage cables can withstand a 26 percent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.

Engineering self-assembling amyloid fibers
Nature has many examples of self-assembly, and bioengineers are interested in copying these systems to create useful new materials or devices. Amyloid proteins, for example, can self-assemble into the tangled plaques associated with Alzheimer's disease -- but can also form very useful materials, such as spider silk, or biofilms around living cells. Researchers at UC Davis and Rice University have now come up with methods to manipulate natural proteins so that they self-assemble into amyloid fibrils.
