Harvard's Wyss Institute develops nanodevice manufacturing strategy using DNA 'building blocks'
Researchers at the Wyss Institute at Harvard University have developed a method for building complex nanostructures out of interlocking DNA "building blocks" that can be programmed to assemble themselves into precisely designed shapes. With further development, the technology could one day enable the creation of new nanoscale devices that deliver drugs directly to disease sites.

'Unzipped' carbon nanotubes could help energize fuel cells and batteries, Stanford scientists say
Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at Stanford University. Their findings are published in the May 27 online edition of the journal Nature Nanotechnology.

Exotic particles, chilled and trapped, form giant matter wave
Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave, a signature of a state called a Bose-Einstein condensate. A first for subatomic particles, rather than whole atoms, the feat will facilitate study of the physical properties of excitons, which exist only fleetingly yet offer promising applications as diverse as efficient solar energy and ultrafast computing.

Discarded data may hold the key to a sharper view of molecules
There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments.

Nanoparticles seen as artificial atoms
Observing the formation of nanorods in real-time, Berkeley Lab researchers found that nanoparticles become attached to form winding chains that eventually align, attach end-to-end, straighten and stretch into elongated nanowires. This supports the theory of nanoparticles acting like artificial atoms during crystal growth and points the way to future energy devices.

First direct observation of oriented attachment in nanocrystal growth
Berkeley Lab researchers have reported the first direct observation of nanoparticles undergoing oriented attachment, the critical step in biomineralization and the growth of nanocrystals. A better understanding of oriented attachment in nanoparticles is a key to synthesizing new materials with remarkable structural properties.

Sensing the infrared: Researchers improve IR detectors with single-walled carbon nanotubes
Whether used in telescopes or optoelectronic communications, infrared detectors must be continuously cooled to avoid being overwhelmed by stray thermal radiation. Now, a team of researchers from Peking University, the Chinese Academy of Sciences, and Duke University is harnessing the remarkable properties of single-walled carbon nanotubes to create highly sensitive, "uncooled" photovoltaic infrared detectors.

Forensics ferret out fire beetle secret
Black fire beetles of the genus Melanophila possess unusual infrared sensors. Researchers from the University of Bonn and from the Forschungszentrum Jülich have concluded that the beetles' sensors might even be more sensitive that uncooled infrared sensors designed by humans. Having this natural model opens up new perspectives, such as for early warning systems for forest fires. The results have been published in PLoS ONE.

Taking solar technology up a notch
The limitations of conventional and current solar cells include high production cost, low operating efficiency and durability, and many cells rely on toxic and scarce materials. Northwestern University researchers have developed a solar cell that, in principle, will minimize these limitations. In particular, the new solid-state solar cell is the first to solve the problem of the promising but leaky Grätzel cell. The device -- whose electrolyte starts as a liquid but ends up a solid mass -- is inherently stable.

Sequence it…and they will come!
Rapid DNA sequencing may soon become a routine part of each individual's medical record, providing enormous information previously sequestered in the human genome's 3 billion nucleotide bases. This week's Newsfocus section of the journal Science describes recent advances in sequencing technology using a tiny orifice known as a nanopore.
