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. The findings could lead to new understanding of the molecules that drive processes in biology, medical diagnostics, nanotechnology, and other fields.
Scientists from SLAC National Accelerator Laboratory, Stanford University, and Germany have figured out a key part of the industrial process for making methanol. It’s an important step toward improving the process—and eventually realizing the goal of turning a potent greenhouse gas, carbon dioxide, into fuel.
Leica Microsystems has introduced the Leica DM4000 B LED, a microscope system with LED illumination suited for biomedical applications.
Gilson Inc. has introduced the GX-241 liquid handler, a compact liquid handler suited for application and laboratories where bench space is at a premium.
Sensors that work flawlessly in laboratory settings may stumble when it comes to performing in real-world conditions, according to researchers at Oak Ridge National Laboratory. These shortcomings are important as they relate to safeguarding the nation's food and water supplies.
Lawrence Berkeley National Laboratory 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.
As malware threats expand into new domains and increasingly focus on industrial espionage, Georgia Institute of Technology researchers are launching a new weapon to help battle the threats: A malware intelligence system that will help corporate and government security officials share information about the attacks they are fighting.
In quantum physics physical processes in condensed matter and other many-body systems can often be described with quasiparticles. For the first time, a team of physicists in Austiri has succeeded in experimentally realizing a new quasiparticle— a repulsive polaron—in an ultracold quantum gas.
The contention of a major but controversial new theory to explain nanocrystal growth is that nanoparticles can act as “artificial atoms,” forming molecular-type building blocks that can assemble into complex structures. The conclusion is based on recent observations of growing nanorods made by Lawrence Berkeley National Laoratory researchers using transmission electron microscopy and advanced liquid cell handling techniques.
Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing.
The scientific and technological literature is abuzz with nanotechnology and its manufacturing and medical applications. But it is in an area with a less glitzy aura—plant sciences—where nanotechnology advancements are contributing dramatically to agriculture. Researchers at Iowa State University have now demonstrated the ability to deliver proteins and DNA into plant cells, simultaneously.
Doping may be a no-no for athletes, but researchers at the University of Florida say it was key in getting unprecedented power conversion efficiency from a new graphene solar cell created in their laboratory.
Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave. This feat will allow scientists to better study the physical properties of excitons, which exist only fleetingly yet offer promising applications as diverse as efficient harvesting of solar energy and ultrafast computing.
The unilateral efforts of a single country or region to reduce the emissions of greenhouse gases could reduce exports, increase imports and lead to higher emissions elsewhere—what economists call "leakage." Unilateral efforts could, however, work better if other sources of energy were used as substitutes, thereby creating "negative leakage," according to research by University of Illinois energy policy experts.
U.S. factories produce about 75% of what the country consumes, but the right decisions by both business and political leaders could push that to 95%, say University of Michigan researchers.
