Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
Unlocking the potential of anti-perovskites through a convenient one-step synthesis route
Although perovskites have attracted a lot of attention lately, anti-perovskites hold just as much potential as functional materials. Bearing a similar crystal structure to perovskites but with an inverted electrical configuration, anti-perovskites ex.....»»
New method enables amplifiable protein identification from trace samples
In a study published in the journal National Science Review, researchers developed an amplifiable protein identification method called "AmproCode.".....»»
Innovative use of hyperspectral data and DCGANs enhances rice protein content estimation
Rice (Oryza sativa L.) is a crucial crop feeding over half of the global population. The demand for high-quality, protein-rich rice is rising, making accurate grain protein content (GPC) estimation vital for breeding superior varieties......»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»
Novel strategy proposed for selectively targeting G-quadruplex at specific genome loci
DNA G-quadruplexes (G4s) are a type of quadruple helix structure formed by a continuous guanine-rich DNA sequence. Although DNA G4s are thought to be involved in various biological processes, in many cases their causative effects are largely unclear.....»»

Researchers at the Department of Medical Biochemistry and Biophysics at Karolinska Institutet have characterized a novel GTPase involved in ribosome production in mitochondria. The study, published in Nature Communications, provides new insights into.....»»
Scientists investigate fast reaction dynamics in synthetic molecules immobilized in porous protein cages
Immobilizing small synthetic molecules inside protein crystals proves to be a promising avenue for studying intermediate compounds formed during chemical reactions, report scientists from Tokyo Tech. By integrating this method with time-resolved seri.....»»
Pongamia trees grow where citrus once flourished, offering renewable energy and plant-based protein
An ancient tree from India is now thriving in groves where citrus trees once flourished in Florida, and could help provide the nation with renewable energy......»»
Researchers reveal how plants protect themselves from viral infection by regulating deacetylation
In a paper published in Science Bulletin, a team of Chinese scientists demonstrated that TaSRT2 recognized viral protein P153 and induced wheat resistance to CWMV through inhibition of the TaSRT2-mediated deacetylation of H3K9ac and H3K79ac, which ev.....»»
Pear-derived discovery: A genetic mechanism to fortify crops against drought
A recent study has shed light on a critical genetic mechanism that boosts plants' ability to withstand drought. The research uncovers the role of the transcription factor PbERF3, native to wild pears, which works in concert with the protein PbHsfC1a.....»»
Investigations of the polysomatism of antigorite under pressure
Antigorite is a type of serpentine, which is the most abundant hydrated mineral on the Earth. It is widely believed that this mineral is the main carrier of water deep into the Earth in subducting oceanic plates. It has a wavy structure along the a-a.....»»
Study finds ways to enhance transcription factor activity
Transcription factors regulate gene expression by binding specific sequences on DNA, which is an essential step to producing messenger RNAs from protein-coding genes. Denes Hnisz's lab, in collaboration with Martin Vingron's lab at the MPIMG, has dis.....»»
Researchers synthesize garnet-rich lunar rock to study moon"s mantle
Our present-day moon has an interior structure containing a central metallic core, overlain by a mantle comprised of minerals such as olivine and pyroxene (e.g. Ol+Px mantle) underneath a shell of crust. Such a picture of the moon's interior has been.....»»
Novel universal principle guides properties of fluorophosphate glass
A research team led by Prof. Wang Pengfei from Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences revealed the relationship between F/O ratio and the structure of fluorophosphate glass through conducting comp.....»»
Researchers uncover key mechanisms in chromosome structure development
Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the organization of chromosomes appears in the Proceeding.....»»
High-precision infrared imaging technology reveals the magnetic domain structure of non-collinear antiferromagnets
Non-collinear antiferromagnetic materials, which have a net magnetic moment of nearly zero, yet exhibit significant anomalous transverse transport properties, are considered candidate materials for the next generation of spintronic devices......»»
Martian meteorites deliver a trove of information on red planet"s structure
