Galactic Brightness Helps Build Precision Model Of The Universe
2012-01-12 04:39:50

Berkeley Lab scientists and their Sloan Digital Sky Survey colleagues use galactic brightness to build a precision model of the cosmos Since 2000, the three Sloan Digital Sky Surveys (SDSS I, II, III) have surveyed well over a quarter of the night sky and produced the biggest color map of the universe in three dimensions ever. Now scientists at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) and their SDSS colleagues, working with DOE´s...

Image 1 - Researchers Use Nanophotonics For Optical Look Inside Living Cells
2011-12-22 05:10:27

An endoscope that can provide high-resolution optical images of the interior of a single living cell, or precisely deliver genes, proteins, therapeutic drugs or other cargo without injuring or damaging the cell, has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab). This highly versatile and mechanically robust nanowire-based optical probe can also be applied to biosensing and single-cell electrophysiology. A team...

Berkeley Lab Researchers Find Evidence Suggesting Risk May Not Be Proportional to Dose at Low Dose Levels Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab), through a combination of time-lapse live imaging and mathematical modeling of a special line of human breast cells, have found evidence to suggest that for low dose levels of ionizing radiation, cancer risks may not be directly proportional to dose. This contradicts the...

Image 1 - New Path To Flex And Stretch Electronics
2011-12-14 05:49:35

Berkeley Lab Researchers Develop Solution-based Fabrication Technique Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make “smart devices” nearly ubiquitous. Among the applications that have been envisioned are electronic pads that could be folded away like paper, coatings that could monitor surfaces for cracks and other structural failures, medical bandages that could treat infections and...

Structural studies at Berkeley Lab´s Advanced Light Source could point to reduced carbon emissions and stronger cements It's no surprise that humans the world over use more water, by volume, than any other material. But in second place, at over 17 billion tons consumed each year, comes concrete made with Portland cement. Portland cement provides the essential binder for strong, versatile concrete; its basic materials are found in many places around the globe; and, at about $100 a ton,...

Berkeley Researchers Say Co-design May Be the Answer to Modeling Clouds and Other Big Problems As sophisticated as modern climate models are, one critical component continues to elude their precision–clouds. Simulating these fluffy puffs of water vapor is so computationally complex that even today´s most powerful supercomputers, working at quadrillions of calculations per second, cannot accurately model them. “Clouds modulate the climate. They reflect some sunlight back...

Joint BioEnergy Institute (JBEI) Researchers Reach Milestone on the Road to Biofuels A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel and jet fuels with a domestically-produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) have engineered the first strains of  Escherichia coli bacteria that can digest switchgrass biomass and synthesize its...

Berkeley Lab Researchers Find Simpler Approach to Making Plasmonic Materials The question of how many polyhedral nanocrystals of silver can be packed into millimeter-sized supercrystals may not be burning on many lips but the answer holds importance for one of today´s hottest new high-tech fields — plasmonics! Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) may have opened the door to a simpler approach for the...

Image 1 - Researchers Create First Of Its Kind Gene Map Of Sulfate-reducing Bacterium
2011-11-10 04:24:43

Work Holds Implications for Future Bioremediation Efforts Critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment have been revealed in a study by researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have provided the first ever map of the genes that determine how these bacteria interact with their surrounding environment. “Knowing how...
