Scientists at Argonne National Laboratory have discovered a way to use a microscopic, swirling flow to rapidly clear a circle of tiny bacteria or swimming robots.
Using cryo-electron microscopy, Berkeley Lab scientist Eva Nogales and her team have made a breakthrough in our understanding of how our molecular machinery finds the right DNA to copy for making proteins, showing with unprecedented detail the role of a powerhouse transcription factor known as TFIID. The study was published this week in Nature.
Researchers at Oak Ridge National Laboratory made a better thermoplastic by replacing styrene with lignin, a brittle, rigid polymer that, with cellulose, forms the woody cell walls of plants.
Physicist Tyler Abrams has led experiments on a facility in the Netherlands called Magnum-PSI showing that combining lithium with the hydrogen isotope deuterium substantially reduced lithium erosion.
Researchers at Oak Ridge National Laboratory and the National Institute of Standards and Technology demonstrated a nondestructive way to observe nanoscale objects and processes in conditions simulating their normal operating environments.
In December, the ATLAS and CMS experiments reported what could be the first hint of a new massive particle that spits out two photons as it decays. Now, physicists are presenting their latest analyses at the Moriond conference in La Thuile, Italy, including a full investigation of this mysterious bump. After carefully checking, cross-checking and rechecking the data, both experiments have come to the same conclusion--the bump is still there.
A new, highly permeable carbon capture membrane developed at Berkeley Lab could lead to more efficient ways of separating carbon dioxide from power plant exhaust, preventing the greenhouse gas from entering the atmosphere and contributing to climate change.
Two-dimensional electronic devices could inch closer to their ultimate promise of low power, high efficiency and mechanical flexibility with a processing technique developed at Oak Ridge National Laboratory.
Scientists have developed a device that enables NMR spectroscopy, coupled with a powerful molecular sensor, to analyze molecular interactions in viscous solutions and fragile materials such as liquid crystals. In a first, their method allows the sensor, hyperpolarized xenon gas, to be dissolved into minute samples of substances without disrupting their molecular order.
Researchers have combined advanced in-situ microscopy and theoretical calculations to uncover important clues to the properties of a promising next-generation energy storage material for supercapacitors and batteries.
New ORNL measurement and data analysis techniques could provide insight into performance-robbing flaws in crystalline structures, ultimately improving the performance of solar cells.
Article describes possible new paradigm for inertial confinement fusion technique.
Microbes in soil - organisms that exert enormous influence over our planet's carbon cycle - may not be as adaptable to climate change as most scientists have presumed, according to the results of a 17-year "soil transplant" on a mountainside in eastern Washington.
In experiments carried out partly at the Department of Energy's SLAC National Accelerator Laboratory, scientists have determined in atomic detail how a potential drug molecule fits into and blocks a channel in cell membranes that Ebola and related "filoviruses" need to infect victims' cells.
Researchers at Berkeley Lab have developed a new materials recipe for a battery-like hydrogen fuel cell that shields the nanocrystals from oxygen, moisture and contaminants while pushing its performance forward in key areas.
Here are five ways SLAC's X-ray laser and the science it enables can impact our future.
Inexpensive materials called MOFs pull gases out of air or other mixed gas streams, but fail to do so with oxygen. Now, a team has overcome this limitation by creating a composite of a MOF and a helper molecule in which the two work in concert to separate oxygen from other gases simply and cheaply, they report in Advanced Materials.
A study led by the University of Tennessee and the Department of Energy's Oak Ridge National Laboratory could soon pay dividends in the development of materials with energy-related applications.
A novel technique known as in-situ plasma processing is helping scientists get more neutrons and better data for their experiments at the Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory.
Cutting-edge simulations run at Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center have yielded exciting answers to long-standing questions about plasma heat loss that have previously stymied efforts to predict the performance of fusion reactors.
PPPL Engineers Design and Build State-of-the-Art Controller for AC to DC Converter That Manages Plasma in Upgraded Fusion Machine
Engineers at PPPL have developed an updated version of a key electronic component that helps regulate the current that powers the coils in PPPL's recently completed National Spherical Torus Experiment-Upgrade.
Clouds are notoriously hard to simulate in computer programs that model climate. A new study in the Proceedings on the National Academy of Sciences Early Edition suggests why -- either clouds are more variable than scientists give them credit for, or those bright white clouds in the sky are much dirtier than scientists thought.
At Argonne National Laboratory, two scientists work on simulations that project what the climate will look like 100 years from now. Last year, they completed the highest-resolution climate forecast ever done for North America, dividing the continent into squares just over seven miles on a side--far more detailed than the standard 30 to 60 miles.
Simulation results could lead to lower production costs for biofuels; New app provides fuel economy information and more to buyers on the go; ORNL supercomputer, SNS offer insight into disease; Advanced heat pump provides hot savings
Argonne and Los Alamos National Laboratories Team Up to Develop More Affordable Fuel Cell Components
Researchers at the U.S. Department of Energy's (DOE) Argonne and Los Alamos national laboratories have teamed up to support a DOE initiative through the creation of the Electrocatalysis Consortium (ElectroCat), a collaboration devoted to finding an effective but cheaper alternative to platinum in hydrogen fuel cells.
