Thanks to trapped electrons, a material expected to be a conducting metal remains an insulator
New research sheds light on the mechanism behind how a special material changes from an electrically conducting metal to an electric insulator. The researchers studied lanthanum strontium nickel oxide (La1.67Sr0.33NiO4) derived from a quantum materia.....»»
Researchers investigate rotation in solar transition region
The solar transition region, located between the chromosphere and corona, plays an important role in the formation of solar wind and coronal heating mechanism. The solar transition region is not a statically layered structure, but a dynamic region wi.....»»
The structure of a protein bound to DNA reveals how the toxicity of the cholera bacterium is activated
Understanding the molecular mechanism that triggers disease is essential for identifying new treatments. Cholera, a disease caused by the bacterium Vibrio cholerae, is no exception......»»
Neutron beam measurements reveal shrinking mechanism of microgels in colloids
Researchers at PSI and the University of Barcelona have managed to explain the strange behavior of microgels. Their measurements using neutron beams have pushed this measuring technique to its limits. The results open up opportunities for new applica.....»»
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 at Kanazawa University report in Science Advances high-speed atomic force microscopy experiments that show the structural and chemical changes in an enzyme thought to play a vital role in modulating the strength of neural connections......»»
Researchers grow precise arrays of nanoscale LEDs
Halide perovskites are a family of materials that have attracted attention for their superior optoelectronic properties and potential applications in devices such as high-performance solar cells, light-emitting diodes, and lasers......»»
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.....»»
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......»»
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.....»»
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.....»»
Directly imaging quantum states in two-dimensional materials
When some semiconductors absorb light, excitons (or particle pairs made of an electron bound to an electron hole) can form. Two-dimensional crystals of tungsten disulfide (WS2) have unique exciton states that are not found in other materials. However.....»»
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.....»»
