Gene fusion as an important mechanism to generate new genes in Oryza genomes
Events of gene fusion have been reported in several organisms. However, the role of gene fusion as part of new gene origination remains unknown. Evolutionary new genes, fused from more than two parental genes, can duck out of the detrimental step of.....»»
Scientists unravel mysterious mechanism behind "whisker crystal" growth
Scientists from Tokyo Metropolitan University have discovered the mechanism behind the rapid growth of ultra-thin nanowires or "whiskers" in organic compounds. Nanowires are both a desirable technological innovation and a hazard when they short elect.....»»
Attosecond-scale measurement of Wigner time delay in molecular photoionization
The photoelectric effect is one of the most fundamental light-matter interactions, which is widely used in probing ultrafast dynamics in atoms, molecules and condensed matters. It has been in the research spotlight for more than 100 years and most of.....»»
Discovery of new COVID infection mechanism offers clue to SARS-CoV-2 leap to humans
The original SARS-CoV-2 viral strain that emerged in early 2020 was able to latch on to sugars known as sialic acids, found on the surface of human cells, an ability that later strains did not retain......»»
Researchers reveal new molecular mechanism for Parkinson"s disease risk
In about a fifth of the cases of Parkinson's disease, look to a small, malfunctioning protein in the lysosome as a risk factor, say University of Michigan researchers......»»
Unveiling the mechanism by which light regulates rice flowering time
Light affects most organisms. In plants, many behaviors and functions are determined by the length of light and dark cycles, including flowering. In the most recent publication of The Proceedings of the National Academy of Sciences (PNAS), a team of.....»»
Researchers discover new endoplasmic reticulum sorting mechanism in plants
Protein sorting in the secretory pathway is essential for cellular compartmentalization and homeostasis in eukaryotic cells. The endoplasmic reticulum (ER) is the biosynthetic and folding factory of secretory cargo proteins. The cargo transport from.....»»
New class of excitons with hybrid dimensionality in layered silicon diphosphide

Relationship between silver nanowire film plasticity and shear fracture resistance
A research team led by Ji Shulin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) studying the mechanism of silver nanowire films has recently discovered that the better the plasticity of the films, the more resi.....»»
Disinfectant mechanism of nano-sized electrostatic atomized water particles on SARS-CoV-2
Current disinfection strategies have major drawbacks, which is why the World Health Organization does not advise routine spraying or fogging of biocidal agents, or UV light sterilization, in occupied areas. One possible alternative is nano-sized elec.....»»
Dying stars could seed interstellar medium with carbon nanotubes
Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation and survival of complex ca.....»»
Formation and evolution of massive binaries may share the same mechanism in Milky Way and Andromeda galaxies
