Mechanism of cobalt–manganese catalysts deciphered
Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are expensive. However, cheaper alternatives have been developed, for example cobalt–manganese catalysts. They have a high activity and are st.....»»
Unlocking long-term genetic memory: Dormant bacterial spores offer key insights into evolutionary survival strategies
A recent study spearheaded by Prof. Sigal Ben Yehuda and her team at Hebrew University has unveiled a captivating facet of bacterial dormancy. Their research illuminates the mechanism through which dormant bacterial spores uphold and activate an endu.....»»
Researchers identify "unicorn" defense mechanism that protects bacteria from antibiotics
Researchers at McMaster University have discovered unique characteristics of a mechanism used by bacteria to resist an important class of antibiotics. The new research, published in Nature Chemical Biology, shows that resistance to aminoglycoside dru.....»»
Combining extreme-ultraviolet light sources to resolve a quantum mechanical dissociation mechanism in oxygen molecules
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another step towards specific q.....»»
Northvolt develops cobalt-free battery cell that could power future EVs
Northvolt says the sodium-ion cell has a “best-in-class” energy density of more than 160 watt-hours per kilogram, and is made without any lithium, nickel, cobalt or graphite......»»
Study sheds new light on mechanism of robust motility of flagellated bacteria
Flagellated bacteria are propelled by the rotation of helical flagellar filaments, each with a flagellar motor at its base. Taking Escherichia coli (E. coli) as an example, each cell has 3–7 flagella whose rotation as a helical bundle enables the c.....»»
How to develop bio-inspired catalysts
Victor Mougel is an absolute fan of nature, not only because he grew up on a farm, spends a lot of time outdoors with his wife and children, and sometimes rides up and down Swiss mountains on his road bike. He also believes that no chemist can hold a.....»»
Research reveals molecular mechanism of asymmetric calcium-sensitive receptor activation
Calcium-sensing receptors (CaSRs), widely distributed in tissues and organs such as parathyroid glands, intestines, bones and kidneys, sense the concentration of calcium ions in the blood and maintain the calcium balance in the human body. CaSR is so.....»»
How green algae count cell divisions illuminates key step needed for the evolution of multicellular life
An international research team led by James Umen, Ph.D., member, Donald Danforth Plant Science Center has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division. Chlamyd.....»»
The unsafe Safeguard Mechanism: How carbon credits could blow up Australia"s main climate policy
A time bomb is ticking inside the Albanese government's climate policy. When it explodes, Australia will fall short of its climate targets and leave a gaggle of investors shirtless......»»
Researchers develop cheap and efficient ethanol catalyst from laser-melted nanoparticles
Ethanol fuel cells are regarded as promising sources of green electricity. However, expensive platinum catalysts are used in their production. Research on laser melting of suspensions carried out at the Institute of Nuclear Physics of the Polish Acad.....»»
Crumpled sheets reveal a mechanism for glassy relaxations
We often crumple a scrap piece of paper into a ball before throwing it. This mundane action, however, creates a unique complex system with surprising mechanical properties. Take a thin plastic sheet such as cellophane and try it yourself. While a reg.....»»
Research explores molecular basis of ventilator-induced diaphragm weakness
A study, published in PNAS Nexus, presents evidence that mitochondrial fragmentation is a proximal mechanism underlying ventilator-induced diaphragm dysfunction (VIDD)—and identifies a possible therapeutic to limit diaphragm atrophy during a stay.....»»
Identifying a silicon transporter to improve the yield of rice
Silicon (Si) is abundant in terrestrial environments and accounts for 0.1% to 10% of a plant's dry weight. Certain plant species show high levels of Si accumulation, and research has identified high Si accumulation as a protective mechanism against a.....»»
Microsoft Authenticator suppresses suspicious MFA notifications
Microsoft has quietly rolled out a new mechanism that shields users of its mobile Authenticator app from suspicious (and annoying) push notifications triggered by attackers. Preventing attacks relying on MFA fatigue When faced with MFA-protected acco.....»»
How lab-made catalysts can help convert difficult greenhouse gases
Natural gas consists of light hydrocarbons such as methane and ethane. Such gases are more potent greenhouse gases than CO2, are constantly released into the atmosphere from natural gas wells, and are more difficult to store than, for example, their.....»»
The cell"s "read–write" mechanism: Researchers uncover how instructions for gene expression are relayed
The "read–write" mechanism by which cells replicate and use chemical instructions for expressing genes has been uncovered by RIKEN researchers. The quality and quantity of gene expression correlates not only with instructions by transcription facto.....»»
Scientists reveal new mechanism for dynamic regulation of manchette microtubules during sperm development
Researchers led by Meng Wenxiang from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences have shown that knocking out of the calmodulin-regulated spectrin-associated protein 1 (CAMSAP 1) gene, which is associated w.....»»
NASA"s robotic prospectors are helping scientists understand what asteroids are made of, setting the stage for mining
The cars, cellphones, computers and televisions that people in the U.S. use every day require metals like copper, cobalt and platinum to build. Demand from the electronics industry for these metals is only rising, and companies are constantly searchi.....»»
