Dynamic z-scanning for ultrafast auto-focusing in laser processing
In laser-based manufacturing, accommodating non-flat, or changing surfaces has traditionally been labor-intensive, involving complex focus mapping procedures and or ex-situ characterization. This often results in repositioning errors and extended pro.....»»
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.....»»
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.....»»
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......»»
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.....»»
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.....»»
Researchers reveal hidden sensory mechanism of hair follicles
Imperial researchers have discovered a hidden mechanism within hair follicles that allow us to feel touch. The findings have been published in Science Advances......»»
Ultrafast X-ray pulses force atoms to give up their electronic secrets
A new spectroscopy technique developed by RIKEN researchers could help reveal the inner workings of metal catalysts and the proteins involved in photosynthesis in plants......»»
Google payment to Apple concerned search giant execs – wanted to use EU law to reduce it
A new report says that the growing size of the Google payment to Apple to remain the default search engine on Apple devices concerned senior execs at the search giant – and they wanted to use EU law as a mechanism to reduce it. One legal academi.....»»
A mechanism that controls the genomic structure during early differentiation into neuroectoderm
A group of scientists have discovered that a one of the components of the polycomb-type of transcriptional repressor complex (PRC), Phc1 (Rae28), regulates the chromatin state of cells and plays a critical role in the process of undifferentiated cell.....»»
Researchers propose new strategy to improve efficiency for nanotherapeutic delivery in tumors
A team led by Prof. Wang Yucai and Associate Prof. Jiang Wei from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) revealed the mechanism of the tumor vascular basement membranes (BM) blocking nanopart.....»»
International team develops novel DNA nano engine
An international team of scientists has recently developed a novel type of nano engine made of DNA. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a d.....»»
Manipulating collective motions of electrons and solvent molecules in a polar liquid
