Laboratory solar flares reveal clues to mechanism behind bursts of high-energy particles
Simulating solar flares on a scale the size of a banana, researchers at Caltech have parsed out the process by which these massive explosions blast potentially harmful energetic particles and X-rays into the cosmos. Their research is published in the.....»»
Manganese in Central Valley water threatens fetuses and children
Water in California's Central Valley contains enough manganese to cause cognitive disabilities and motor control issues in children, and Parkinson's-like symptoms in adults......»»
Microbiologists discover a regulatory mechanism that keeps cancer-causing bacteria in check
Researchers at the Forsyth Institute have discovered an important mechanism that may have profound implications for how we prevent colorectal cancer. Oddly enough, their discovery began in the mouth......»»
Researchers reveal mechanism of polarized cortex assembly in migrating cells
The cell cortex is defined as a thin layer of filamentous actin, myosin motors, and regulatory proteins beneath the plasma membrane. Assembly and contraction of this actin meshwork generates cortical tension, which enables cells to resist external me.....»»
New research roots out new mechanism for branching in plants
Researchers have revealed for the first time how a mechanism that controls root development in plants enables them to cope better with environmental stress conditions......»»
Calcium sensor helps us to see the stars
Using cryo-electron microscopy and mass spectrometry, researchers from PSI have deciphered the structure of an ion channel found in the eye while it interacts with the protein calmodulin—a structure that has eluded scientists for three decades. The.....»»
Study: Visible light induces bacteria to produce superoxide for manganese oxidation
Manganese oxides are natural reactive minerals and widely spread in aquatic and terrestrial environments, affecting the fate of metals (such as As3+ and Cd2+) and organic pollutants (such as phenols and diclofenac) through adsorption and oxidation in.....»»
Researchers explore effects of fully relativistic condition on electron cyclotron maser emission
Radio emission, carrying a wealth of information, is critical for understanding the physical process of various outbursts. The electron cyclotron maser emission (ECME) plays an important role as a coherent radiation mechanism in explaining radio emis.....»»
Ford joins a US$4.51 billion nickel processing project in Indonesia
US automaker Ford made a battery material investment in Indonesia, a first for the company in Southeast Asia. The US$4.51 billion project is also joined by PT Vale Indonesia and Huayou Cobalt, targeting 120 kilotons of mixed hydroxide precipitate (MH.....»»
Review: Iridium-based catalysts look set to boost efficiency of green hydrogen production
Hydrogen production powered by wind and solar energy is still too expensive if it is to play a role in the clean transition via energy storage and to help decarbonize hard-to-electrify sectors. Much effort in reducing its cost focuses on enhancing pr.....»»
Breaking the barrier: Low-temp ammonia synthesis with iron catalysts and barium hydride
The Haber-Bosch (HB) process is one of the most important industrial chemical reactions. It combines nitrogen and hydrogen gases in the presence of an iron-based catalyst at high temperatures and pressures to produce ammonia fertilizer which helps pr.....»»
Australia will have a carbon price for industry, and it may infuse greater climate action across the economy
Australia is about to take a big, constructive step on climate change policy: we will have a carbon price for the industry sector, under the safeguard mechanism......»»
Structure of "oil-eating" enzyme opens door to bioengineered catalysts
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first and most challenging step in turning simple hydrocarbons.....»»
Key mechanism that controls human heart development discovered
Writing in Science Advances researchers of the University of Cologne describe a key mechanism that controls the decision-making process that allows human embryonic stem cells to make the heart. These discoveries enable better insights into how the hu.....»»
New insights into an old drug: Scientists discover why aspirin works so well
New research has revealed important information about how aspirin works. Even though this drug has been available commercially since the late 1800s, scientists have not yet fully elucidated its detailed mechanism of action and cellular targets. The n.....»»
Arm to change license fee charging formula, heaping pressure on chipmakers
British silicon IP provider Arm reportedly has notified its major customers about a sharp adjustment in its future licensing fee collection mechanism starting 2024, when the fee will be calculated based on the value of each end product instead of the.....»»
Synergistic iron carbide catalysts enable direct conversion of syngas into higher alcohols
