Speeding The Search For A Better Way To Capture Methane
2013-04-25 09:46:05

Lawrence Berkeley National Laboratory Like the Roman god Janus, methane presents Earth´s atmosphere with two situational faces. As the main component of natural gas, methane when burned as a fuel produces less carbon dioxide than the burning of oil or coal, which makes it a plus for global climate change. However, pure methane released into the atmosphere via leaks from unconventional oil and gas extraction, coal mining or from the melting of Arctic ice is an even more potent...

Cuts in federal funding of nanotechnology research threaten to slow progress toward some of the field's greatest promises, including commercialization of sustainable new energy sources that do not contribute to global warming, an international authority in the field cautioned here today. Speaking at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, A. Paul Alivisatos, Ph.D., expressed concern that the cuts come when...

Lawrence Berkeley National Laboratory Your cells are social butterflies. They constantly interact with their surroundings, taking in cues on when to divide and where to anchor themselves, among other critical tasks. This networking is driven in part by proteins called integrin, which reside in a cell´s outer plasma membrane. Their job is to convert mechanical forces from outside the cell into internal chemical signals that tell the cell what to do. That is, when they work properly....

Surprising Control Over Photoelectrons From A Topological Insulator
2013-03-13 15:22:44

Lawrence Berkeley National Laboratory Berkeley Lab scientists discover how a photon beam can flip the spin polarization of electrons emitted from an exciting new material Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface. Researchers find TIs exciting partly because the electrons...

Far-reaching Problem In Computer Simulations Deciphered By Scientists
2013-01-03 12:19:27

DOE/Lawrence Berkeley National Laboratory Because modern computers have to depict the real world with digital representations of numbers instead of physical analogues, to simulate the continuous passage of time they have to digitize time into small slices. This kind of simulation is essential in disciplines from medical and biological research, to new materials, to fundamental considerations of quantum mechanics, and the fact that it inevitably introduces errors is an ongoing problem for...

Boosting Biofuel Production By Boosting Galactan Sugars
2012-12-21 17:18:07

Lawrence Berkeley National Laboratory Collaboration at JBEI Identifies the First Enzyme Linked to Galactan Synthesis Galactan is a polymer of galactose, a six-carbon sugar that can be readily fermented by yeast into ethanol and is a target of interest for researchers in advanced biofuels produced from cellulosic biomass. Now an international collaboration led by scientists at the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) has identified the first enzyme...

the search for dark energy

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Starting in early 2013 redOrbit will be launching a new podcast series called Your Universe Today, where we interview leading scientists about cutting-edge research in everything from space travel to the origins of our Universe. But we´re in the holiday spirit and couldn´t wait until January to unveil our new podcast project, so we´ve decided to give you a sneak peak of what´s to come. In the...

Real-Time CT-Scan Test Rig For Ceramic Composites At Ultrahigh Temperatures Developed
2012-12-10 16:41:08

Lawrence Berkeley National Laboratory Advanced ceramic composites can withstand the ultrahigh operational temperatures projected for hypersonic jet and next generation gas turbine engines, but real-time analysis of the mechanical properties of these space-age materials at ultrahigh temperatures has been a challenge — until now. Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first testing facility...
