Public Release: 23-May-2012
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.

Making microscopic machines using metallic glass
Researchers in Ireland have developed a new technology using materials called bulk metallic glasses to produce high-precision molds for making tiny plastic components. The components, with detailed microscopically patterned surfaces could be used in the next generation of computer memory devices and microscale testing kits and chemical reactors.

How ion bombardment reshapes metal surfaces
Ion bombardment of metal surfaces is an important, but poorly understood, nanomanufacturing technique. New research using sophisticated supercomputer simulations has shown what goes on in trillionths of a second. The advance could lead to better ways to predict the phenomenon and more uses of the technique to make new nanoscale products.

UCLA researchers develop way to strengthen proteins with polymers
In a new study published in the Journal of the American Society of Chemistry, investigators from the UCLA Department of Chemistry and Biochemistry and the California NanoSystems Institute at UCLA describe how they synthesized polymers to attach to proteins in order to stabilize them during shipping, storage and other activities. The study findings suggest that these polymers could be useful in stabilizing protein formulations.

Reversible doping: Hydrogen flips switch on vanadium oxide
If you are not a condensed matter physicist, vanadium oxide may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to reversibly alter VO2's electronic properties by treating it with one of the simplest substances -- hydrogen.

Cloak of invisibility: Engineers use plasmonics to create an invisible photodetector
A team of engineers at Stanford and the University of Pennsylvania has for the first time used "plasmonic cloaking" to create a device that can see without being seen – an invisible machine that detects light. It is the first example of what the researchers describe as a new class of devices that controls the flow of light at the nanoscale to produce both optical and electronic functions.
