As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. B.....»»
LA"s water supplies are in good shape: But is the city ready for the next drought?
California's second wet winter in a row has left L.A's water supplies in good shape for at least another year, but the inevitable return to dry conditions could once again put the city's residents in a precarious position......»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Scientists experimentally observe current-driven antiskyrmion sliding
Prof. Zhang Ying's group from the Institute of Physics of the Chinese Academy of Sciences (CAS), in collaboration with domestic universities and the Los Alamos National Laboratory in the United States, has experimentally observed current-driven antis.....»»
Researchers create nanomembrane to increase reaction rate in chemical production
Flow-through reactors packed with enzymes can produce certain chemicals in a gentle and careful way. However, their performance has so far been limited. A research team from the Helmholtz-Zentrum Hereon and RWTH Aachen University has now been able to.....»»
Data-driven music: Converting climate measurements into music
A geo-environmental scientist from Japan has composed a string quartet using sonified climate data. The 6-minute-long composition—titled "String Quartet No. 1 "Polar Energy Budget"—is based on over 30 years of satellite-collected climate data fro.....»»
Mexico, facing U.S. pressure, will halt incentives to Chinese EV makers
Mexico's federal government, under pressure from the U.S., is keeping Chinese automakers at arm's length by refusing to offer such incentives as low-cost public land or tax cuts for investment in EV production, three Mexican officials familiar with t.....»»
El Nino not climate change driving southern Africa drought: Study
A drought that pushed millions of people into hunger across southern Africa has been driven mostly by the El Niño weather pattern—not climate change, scientists said on Thursday......»»
Redgate Monitor Enterprise prevents unauthorized access to sensitive information
Redgate has launched an enterprise version of its popular database monitoring tool, providing a range of new features to address the challenges of scale and complexity faced by larger organizations. Redgate Monitor Enterprise offers advanced capabili.....»»
Enterprises face significant losses from mobile fraud
A recent Enea survey highlights a worrying trend in enterprise security: Following ChatGPT’s launch, 76% of businesses are inadequately protected against rising AI-driven vishing and smishing threats. In this Help Net Security video, John Hughe.....»»
Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery
Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in everyday life, it represents.....»»
NASA to hoist its sail: Solar sail mission gets ready for launch
A NASA mission testing a new way of navigating our solar system is ready to hoist its sail into space—not to catch the wind, but the propulsive power of sunlight. The Advanced Composite Solar Sail System is targeting launch on Tuesday, April 23 (We.....»»
Plugging the leak on laundry pollution
Joaquim Goes, an ocean biochemist at Columbia Climate School's Lamont-Doherty Earth Observatory, had to look twice when he first saw the tiny strands of fiber floating in a water sample from the Hudson River. An expert in microplastics detection, he.....»»
On-demand nutrient production system for long-duration space missions
When astronauts embark on long space missions, they'll need to grow their own food because pre-packaged meals from Earth lose their nutritional value over time. The BioNutrients project at Ames Research Center's Space Biosciences Division has solved.....»»
Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previo.....»»
Anthropocene activities dramatically alter deep underground fluid flux, researchers find
Much of Earth's water is hidden hundreds of meters beneath our feet, among soil particles and deep within rock pores and fractures......»»
New model finds previous cell division calculations ignore drivers at the molecular scale
When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass......»»
T-Mobile and Verizon workers offered $300 bribes for SIM swaps
SIM swaps are one of the biggest security threats we face, allowing criminals to access most services protected by two-factor authentication. The situation could be about to get even worse, as we learn of an apparent large-scale attempt to bribe T-Mo.....»»
East coast mussel shells are becoming more porous in warming waters
Researchers at the American Museum of Natural History have found that over the last 120 years, the porosity—or small-scale holes—in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The stud.....»»
Spintronics: A new path to room temperature swirling spin textures
In some materials, spins form complex magnetic structures within the nanometer and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such structures are magnetic bubbles, skyrmions, and magn.....»»
