The Georgia Institute of Technology has won a $6 million federal grant to design improvements that strengthen the performance and safety of nuclear systems beyond today's capabilities. The three-year project will engage universities, industry partners, and international organizations to develop a novel concept of a light water reactor with inherent safety features.
Understanding why proteins interact with certain specific molecules and not with the myriad others in their environment is a major goal of molecular biology. Now, in a series of recent papers, researchers describe how they designed proteins from scratch to have a high affinity and high specificity for targets on flu viruses, and then validated the two best designs using X-ray diffraction data collected at the Stanford Synchrotron Radiation Lightsource (SSRL).
A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data for a yearlong mission aimed at improving the representation of clouds in climate models.
Anyone who owns an electronic device knows that lithium-ion batteries could work better and last longer. Now, scientists examining battery materials on the nanoscale reveal how nickel forms a physical barrier that impedes that shuttling of lithium ions in the electrode, reducing how fast the materials charge and discharge. The research also suggest a way to improve the materials.
Lawrence Livermore National Laboratory's JASPER gas gun has fired its 100th shot. JASPER (the Joint Actinide Shock Physics Experimental Research) is a key scientific tool for the National Nuclear Security Administrations Stockpile Stewardship Program and its experiments have enabled scientists to understand important properties and behaviors of plutonium and other special nuclear materials without conducting underground nuclear tests.
Scientists at the National Renewable Energy Laboratory have demonstrated a better way to use photosynthesis to produce ethylene, a breakthrough that could change the way materials, chemicals, and transportation fuels are made, and help clean the air. The scientists introduced a gene into a cyanobacterium and demonstrated that the organism remained stable through a least four generations, producing ethylene gas that could be easily captured.
A University of Arkansas physicist and his colleagues have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop unusual magnetic properties.
Imagine a clock that will keep perfect time forever or a device that opens new dimensions into the study of such quantum phenomena as emergence and entanglement. Lawrence Berkeley National Laboratory researchers have proposed a space-time crystal based on an electric-field ion trap and the Coulomb repulsion of particles that carry the same electrical charge.
Accelerator physicists at SLAC National Accelerator Laboratory have started commissioning the world's most compact photoinjector, a device that spits out electrons when hit by light. Photoinjectors are used to generate electrons for free-electron lasers (FELs) like the Linac Coherent Light Source, among other things, and this development could enable much more compact FELs, as well as other types of accelerator-based facilities.
The explosive PETN has been around for a century and is used by everyone from miners to the military, but it took new research by Sandia National Laboratories to begin to discover key mechanisms behind what causes it to fail at small scales. By developing a novel technique based on physical vapor deposition to create samples with varying thickness, the researchers were able to study detonation behavior at the sub-millimeter scale and to determine that PETN detonation fails at a thickness roughly the width of human hair.
Tried-and-true techniques could help optimize oilseed yield for biodiesel production, according to studies conducted by U.S. Department of Agriculture scientists. For more than 30 years, near-infrared reflectance spectroscopy has been used as a rapid and nondestructive method for measuring protein, moisture, and oil levels in whole grains. Now researchers are studying how to use remote sensing tools to quickly assess seed oil quality and quantity before and after harvest.
Using a microscopic optical sensor that can be batch-fabricated on a silicon chip at low cost, researchers from NIST have measured the mechanical motion between two nanofabricated structures with a precision close to the fundamental limit imposed by quantum mechanics.
Researchers at NIST have developed a new computational method for identifying candidate refrigerant fluids with low global warming potential—the tendency to trap heat in the atmosphere for many decades—as well as other desirable performance and safety features. The NIST effort is the most extensive systematic search for a new class of refrigerants that meet the latest concerns about climate change.
Would you like icy organics with that? Maybe not in your coffee, but researchers at NASA's Jet Propulsion Laboratory are creating concoctions of organics, or carbon-bearing molecules, on ice in the laboratory, then zapping them with lasers. Their goal: to better understand how life arose on Earth.
An important test is coming up next week to see whether a heat shield made from the soil of the moon, Mars, or an asteroid will stand up to the searing demands of a plunge through the Earth's atmosphere. At stake is the possibility that future spacecraft could leave Earth without carrying a heavy heat shield and instead make one on the surface of another world and ride it home safely.
When the Dark Energy Camera opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, more than 120 members of the Dark Energy Survey eagerly awaited the first snapshots. Those images have now arrived.
