Plants exhibit a wide range of mechanical properties, engineers find
An MIT researcher has compiled data on the microstructures of a number of different plants and has found that they exhibit an enormous range of mechanical properties, depending on the arrangement of a cell wall's four main building blocks: cellulose, hemicellulose, lignin and pectin.

Nano, photonic research gets boost from new 3-D visualization technology
For the first time X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample. This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro- and nano-electronics. This new technique also reduces "guesswork" by eliminating the need for modeling-dependent structural simulation often used in X-ray analysis.

Lab on a Chip
NIST focuses on testing standards to support lab on a chip commercialization
Lab on a chip (LOC) devices are microchip-size systems that can prepare and analyze tiny fluid samples with volumes ranging from a few microliters (millionth of a liter) to sub-nanoliters (less than a billionth of a liter). A recent paper from the National Institute of Standards and Technology argues that before LOC technology can be fully commercialized, testing standards need to be developed and implemented.

Oh, my stars and hexagons! DNA code shapes gold nanoparticles
DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA's code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles -- tiny gold crystals that have many applications in medicine, electronics and catalysis. Each of the four DNA bases codes for a different gold particle shape: rough round particles, stars, flat round discs, and hexagons.

New phenomenon in nanodisk magnetic vortices
New findings from a team of Berkeley Lab and Japanese scientists suggest that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well. A study at the Advanced Light Source revealed that contrary to suppositions, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon.

Increased productivity, not less energy use, results from more efficient lighting
More light, rather than lower costs, should be the result of increased efficiencies of LED lighting. But productivity will increase.

Quantum physics: New insights into the remote control of quantum systems
An international collaboration led by physicists of the University of Vienna shines new light on the question of the resources required for achieving quantum information processing. The scientists demonstrate that less demanding resources, which are easier to prepare and to control, can be used for quantum-enhanced technologies. In the experiment, which is published in Nature Physics, the researchers achieve remote quantum state preparation without requiring entanglement as a resource.
