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.
Experiments at Berkeley Lab helped scientists zero in on a low-temperature chemical mechanism that may help to explain the complex molecular compounds that make up the nitrogen-rich haze layer surrounding Titan, Saturn's largest moon.
More and more breweries are investing in practices to save energy and reduce greenhouse gases. Will it pay off? A study by Indiana University researchers suggests it may.
Argonne recently held a ribbon-cutting ceremony for the expanded Cell Analysis, Modeling and Prototyping (CAMP) facility.
Magnetic reconnection causes space storms that can damage satellites and disrupt the grid. While it's a common process in the universe, plasma physics researchers don't fully understand why it occurs so abruptly and quickly. New research is supporting a theory that may hold the key.
An analysis of 2,000 nonresidential solar systems in California found that third-party installations have a 4 percent better production yield than systems owned directly by the businesses.
Capturing ultrafast atomic-scale motion could help scientists optimize the performance of materials with strong electronic correlations.
The first-ever detection of highly energetic radiation from a microquasar has astrophysicists scrambling for new theories to explain the extreme particle acceleration. A microquasar is a black hole that gobbles up debris from a nearby companion star and blasts out powerful jets of material.
Engineers have developed a super-hydrophobic surface that can be used to generate electrical voltage. When salt water flows over this specially patterned surface, it can produce at least 50 millivolts. The proof-of-concept work could lead to the development of new power sources for lab-on-a-chip platforms and other microfluidics devices. It could someday be extended to energy harvesting methods in water desalination plants, researchers said.
Fuel cells have long been viewed as a promising power source. But most fuel cells are too expensive, inefficient, or both. In a new approach, inspired by biology, a University of Wisconsin-Madison team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.
Observation could help scientists find the universal key ingredient in the recipe for high-temperature superconductivity.
