X-rays have become laser-like
...scribed above is not new. It has become a standard technique
for routinely producing laser-like extreme ultraviolet radiation at wavelengths down to the 10 nanometer regime. Pushing the frontier of this technology to ever shorter wavelengths has proven ever more difficult because it requires atoms to be expose...
Computer-aided protein design wins prestigious AAAS Newcomb Cleveland Prize
...number of disciplines, the authors applied a novel technique
of iterative computational design to a problem that many had seen as insoluble: the design -- with atomic-level accuracy -- of very large molecules with molecular masses greater than 10,000. This opens up new possibilities for studying the channeling...
ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors
...sampled. The researchers used a chemical analysis technique
called high-performance liquid chromatography to survey the pigments present in red parrot feathers. McGraw and Nogare collected and analyzed samples from 44 parrot species that have red feathers. Overall, there are some 350 species of parrots, 80 pe...

allowed the researchers to gauge from the condition of each population whether its size would be exp...
California researchers help map human genetic variation across populations
...to the maps compiled by Perlegen using a different technique
called 'linkage disequilibrium' (LD). LD involves correlations of DNA variants in physical proximity along a chromosome, and results from a combination of processes including mutation, natural selection, and genetic drift. Linkage disequilibrium is c...
Molecular machine may lead to new drugs to combat human diseases
...llized previously, and the targeted trans-splicing technique
has been used to repair hemoglobin infected with sickle cell anemia. The new structure provides scientists with tools to expand on ways to harness this molecular machine, Golden said. The other researchers on this study were Hajeong Kim, graduate st...
Successful test of single molecule switch opens the door to biomolecular electronics

Olfactory receptor cells may provide clues to psychiatric disease
...the study, researchers used a fluorescence imaging technique
to measure basal and stimulated calcium levels in ORNs from 17 patients with bipolar disorder and age- and sex-matched healthy controls. Seven patients were medication free and 10 were being treated with mood-stabilizing drugs. Calcium responses w...
MGH study identifies potential Alzheimer's risk gene
