Latest Supercomputers Enable High-Resolution Climate Models, Truer Simulation of Extreme Weather

Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, Berkeley Lab climate scientist Michael Wehner was able to complete a run in just three months. What he found was that not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.

Berkeley Lab Scientists ID New Driver Behind Arctic Warming

Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic and melting sea ice. They found that open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.

New Project is the ACME of Addressing Climate Change

Eight Department of Energy national laboratories, including Berkeley Lab, are combining forces with the National Center for Atmospheric Research and other institutions in a project called Accelerated Climate Modeling for Energy, or ACME, which is designed to accelerate the development and application of fully coupled, state-of-the-science Earth system models for scientific and energy applications.

Berkeley Lab Wins Three 2014 R&D 100 Awards

Berkeley Lab has won three 2014 R&D 100 awards. This year’s winners include a fast way to analyze the chemical composition of cells, a suite of genetic tools to improve crops, and a method to screen images of 3-D cell cultures for cancer cells. The technologies could lead to advances in biofuels, food crops, drug development, and biomaterials, and a to better understanding of microbial communities, to name a few potential benefits.

A Glassy Look for Manganites: Berkeley Lab Researchers at the ALS Observe Glass-like Behavior in the Electron-Spins of PCMO Crystals

Researchers at the Advanced Light Source discovered a glass-like re-ordering of electron-spin states as manganite crystals recovered from a photo-excited conductor state back to an insulator state. The discovery holds promise for future ultrafast electronic switching and memory devices.

Discovery of New Semiconductor Holds Promise for 2D Physics and Electronics

Researchers at Berkeley Lab’s Molecular Foundry have discovered a unique new two-dimensional semiconductor, rhenium disulfide, that behaves electronically as if it were a 2D monolayer even as a 3D bulk material. This not only opens the door to 2D electronic applications with a 3D material, it also makes it possible to study 2D physics with easy-to-make 3D crystals.

Cooling Microprocessors with Carbon Nanotubes

Berkeley Lab researchers at the Molecular Foundry have developed a “process friendly” technique to enable the cooling of microprocessor chips through the use of carbon nanotubes.

Roots of the Lithium Battery Problem: Berkeley Lab Researchers Find Dendrites Start Below the Surface

Berkeley Lab researchers have discovered that the dendrite problem that can cause lithium-ion batteries to short-circuit, overheat and possibly catch fire originates below the surface of the lithium electrode and not at the surface as has been widely believed.

Berkeley Lab Researchers Create a Nonlinear Light-generating Zero-Index MetaMaterial

Berkeley Lab researchers have used a unique optical metamaterial with zero-index refraction to generate phase mismatch–free nonlinear light, an important step towards efficient light generation for future quantum networks and light sources.

Diamond Imperfections Pave the Way to Technology Gold

Using ultrafast 2D electronic spectroscopy, Berkeley Lab researchers have recorded unprecedented observations of energy moving through the atom-sized diamond impurities known as nitrogen-vacancy (NV) centers. Their results provide information on NV centers that is important for such highly promising advanced technologies as supersensitive detections of magnetic fields and quantum computing.
