Unraveling the hidden growth of mineral dendrites
An international research team involving scientists from the University of Vienna, the Faculty of Physics of the University of Warsaw and University of Edinburgh has described the process of growing three-dimensional manganese dendrites. The research.....»»
Examining why plants flower early in a warming world
Scientists have unveiled a new mechanism that plants use to sense temperature. This finding could lead to solutions to counteract some of the deleterious changes in plant growth, flowering and seed production due to climate change. The results are pu.....»»
Spherulitic lead calcium apatite could reduce effectiveness of phosphate dosing, study suggests
Small amounts of phosphate are added to tap waters in the UK to prevent lead leaching from lead water pipes via a process known as phosphate dosing. But scientists are not certain how this works and there may even be more than one mechanism......»»
Researchers identify genetic mechanism that controls petal color in lotus
Lotus (Nelumbo) is a basal eudicot with agricultural and horticultural value. It is a worldwide aquatic ornamental belonging to the Nelmbonaceae family with only two species, N. lutea with yellow flowers and N. nucifera with red or white flowers. Alt.....»»
Experiments provide insights into the molecular mechanism for memory and learning

Researchers propose post-synthetic modification of covalent organic frameworks for carbon dioxide electroreduction
Covalent organic frameworks (COFs), possessing ordered pores and high-precision functionalization, are regarded as an ideal class of templates to construct catalysts for electrocatalytic carbon dioxide reduction reaction (CO2RR)......»»
Virus-like transposons cross the species barrier, study shows
Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers from Alejandro Burga's lab at the.....»»
New protein scaffolds for assembling multi-enzyme systems with unprecedented control
Cell-free biocatalysis is being increasingly used as a substitute for conventional chemical catalysts, given that enzymes (biological catalysts) are more sustainable and selective in the manufacture of valuable chemicals. Chemical biomanufacturing ha.....»»
Researchers identify molecular mechanism of cancer invasion
A cancerous tumor is the accumulation of cells uncontrollably dividing, some of which can invade other parts of the body. The process is difficult to predict in detail, and eradicating the cells poses even greater difficulty......»»
GM signs deal with Australian supplier for EV battery raw materials
GM will provide an $85 million loan to help supplier Element 25 fund construction of a $290 million facility in Louisiana to produce manganese sulfate. Production is expected to begin in 2025......»»
Smart yet simple: Creating uniform DNA-encapsulating microgels that mimic a living cell
The living cell harbors physiologically relevant components such as the genetic material (DNA) and proteins in a "self-organized" setting. Understanding this process of self-assembly can reveal the underlying mechanism of self-organization of living.....»»
For EV batteries, lithium iron phosphate narrows the gap with nickel, cobalt
LFP has sparked new interest especially in the U.S., where a clutch of domestic and overseas manufacturers has pledged more than $14 billion in new production facilities......»»
Researchers reveal new molecular mechanism for stimulating hair growth
The process by which aged (senescent) pigment-making cells in the skin cause significant growth of hair inside skin moles, called nevi, has been identified by a research team led by the University of California, Irvine. The discovery may offer a road.....»»
Electron acceleration efficiency during the impulsive phase of a solar flare: X-ray and microwave observations
Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in magnetic reconnection events at the sun (and similar astrophysical settings) presents a major challenge in astro.....»»
Theory"s predictive power: Creating effective and low-cost rare-earth element based catalysts
An international research group has used theoretical predictions to identify and then fabricate a new electrocatalyst that significantly aids the oxygen evolution reaction (OER). Details of their findings were published in the journal Advanced Materi.....»»
Photos: Infosecurity Europe 2023
Infosecurity Europe is taking place at ExCeL London from 20-22 June 2023 and Help Net Security is on site. Here’s a closer look at the conference featuring: Island, Crowdstrike, Panorays, ManageEngine, Mazebolt, Cobalt, Intruder, TikTok, and Ce.....»»
Pheromone found to put scared rats at ease could lead to humane pest control
Some animals release chemical pheromones which can trigger behavioral or hormonal changes in other animals. It is known that calm rats can reduce fear in nearby rats, but the exact mechanism was unknown. Researchers, including those from the Universi.....»»
Scientists quantify regulation factors contributing to flux changes in the central metabolic pathway in yeast
Metabolic reaction flux change is the final result of interacting regulations by intracellular gene expression, transcriptional regulation, protein level, translation modification, and allosteric effect. However, the regulatory mechanism of metabolic.....»»
Embryoids shed light on a complex genetic mechanism
Researchers from EPFL and the University of Geneva (UNIGE) have gained new insights into a mechanism regulating the early-stage development of mouse embryos. Instead of using an animal model, the team carried out their research on pseudo-embryos grow.....»»
Discovery of a new mechanism that may promote healthy aging of our cells
All biological processes in our cells are constantly monitored to prevent the accumulation of defective proteins. In the worst case, such protein clumps can trigger diseases. The synthesis of new proteins is particularly susceptible to errors. Errono.....»»
