Climate scientists have not been properly accounting for what plants do at night, and that, it turns out, is a mistake. A new study from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found that plant nutrient uptake in the absence of photosynthesis affects greenhouse gas emissions to the atmosphere.
New driverless car technologies developed at a University of Delaware lab could lead to a world without traffic lights and speeding tickets. Researchers hope the innovations will bring about the development of driverless cars that use 19 to 22 percent less fuel.
A novel new way to keep oil from clogging filters and equipment
Researchers at Washington University in St. Louis take a closer look at lithium metal plating and make some surprising findings that might lead to the next generation of batteries.
Fuel cell efficiency of hydrogen fuel cells decreases as the Nafion membrane, used to separate the anode and cathode within a fuel cell, swells as it interacts with water. Russian and Australian researchers have now shown that this Nafion separator membrane partially unwinds some of its constituent fibers, which then protrude away from the surface into the bulk water phase for hundreds of microns. Their results were published in this week's Journal of Chemical Physics.
Oak Ridge National Laboratory scientists used neutrons, isotopes and simulations to "see" the atomic structure of a saturated solution and found evidence supporting one of two competing hypotheses about how ions come together to form minerals.
Researchers have developed a new class of molecular layer deposition chemistry that paves the way for a new photoactivated molecular layer deposition technique. They report that their new method will expand the tool kit for forming covalently bound organic multilayers at surfaces. These emerging deposition techniques have enabled engineers to produce organic thin films with improved conformality. Richard Closser, Stanford University, will present the findings at the AVS 65th International Symposium and Exhibition, Oct. 21-26, 2018.
Aspergillus fungi play roles in fields including bioenergy, health, and biotechnology. In Nature Genetics, a team led by scientists at the Technical University of Denmark, the DOE Joint Genome Institute, and the Joint Bioenergy Institute, present the first large analysis of an Aspergillus fungal subgroup, section Nigri.
Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light.
Two researchers with personal experience of hurricanes set out to investigate the role of an underestimated factor in storm's strength - salinity. They found that salinity plays a larger role than anyone thought, including them.
Feature describes unexpected discovery of a role the process that seeds magnetic fields plays in mediating a phenomenon that occurs throughout the universe and can disrupt cell phone service and knock out power grids on Earth.
Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.
Ames Laboratory has developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields.
Argonne scientists have identified a new class of topological materials made by inserting transition metal atoms into the atomic lattice of a well-known two-dimensional material.
New research reveals an unexpected benefit of large-scale offshore wind farms: the ability to lessen precipitation from hurricanes.
PPPL scientists have found evidence suggesting that a process could remove the unwanted ash produced during fusion reactions and make the fusion processes more efficient within a type of fusion facility known as a field-reversed configuration device.
A new study shows how animals use their tails to keep mosquitoes at bay by combining a swish that blows away most of the biting bugs and a swat that kills the ones that get through.
Scientists, including researchers from the Department of Energy's SLAC National Accelerator Laboratory, have compiled the most detailed catalog of such blobs using eight years of data collected with the Large Area Telescope (LAT) on NASA's Fermi Gamma-Ray Space Telescope. The blobs, including 19 gamma-ray sources that weren't known to be extended before, provide crucial information on how stars are born, how they die, and how galaxies spew out matter trillions of miles into space.
Applying Auto Industry's Fuel-Efficiency Standards to Agriculture Could Net Billions in Corn Sector, Researchers Conclude
Adopting benchmarks similar to the fuel-efficiency standards used by the auto industry in the production of fertilizer could yield $5-8 billion in economic benefits for the U.S. corn sector alone, researchers have concluded in a new analysis.
A paper published in Nature Communications by Sufei Shi, assistant professor of chemical and biological engineering at Rensselaer, increases our understanding of how light interacts with atomically thin semiconductors and creates unique excitonic complex particles, multiple electrons, and holes strongly bound together.
Next-Gen Ultrafast Optical Fiber-Based Electron Gun to Reveal Atomic Motions During Transition State
A new method enables researchers to directly observe and capture atomic motions at surfaces and interfaces in real time.
Researchers experimentally observed the ionization-induced channeling of an intense microwave beam propagating through a neutral gas (>103 Pa).
Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then emits light in the near-infrared range. Now a team led by researchers at Lawrence Berkeley National Laboratory has confirmed the pigment's fluorescence can be 10 times stronger than previously thought.
Reported October 8, 2018, in Nature Microbiology, a team led by U.S. Department of Energy Joint Genome Institute researchers developed a pipeline to generate genomes from single cells of uncultivated fungi. The approach was tested on several uncultivated species representing early diverging fungi.
Optical frequency combs can enable ultrafast processes in physics, biology, and chemistry, as well as improve communication and navigation, medical testing, and security. Columbia Engineers have built a Kerr frequency comb generator that, for the first time, integrates the laser with the microresonator, significantly shrinking the system's size and power requirements. They no longer need to connect separate devices using fiber--they can now integrate it all on compact and energy efficient photonic chips.
