How nitrate regulates gene expression in legumes
Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation in these plants has been a my.....»»

Canopy structure regulates autumn phenology by mediating microclimate in temperate forests, finds study
Autumn phenology serves as a sensitive indicator of temperate forests' response to climate change and is a key factor influencing forest carbon sequestration. Understanding the mechanisms driving the spatiotemporal variations in autumn phenology is c.....»»
Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Emotion recognition goes beyond facial expressions, study finds
A person's facial expression provides crucial information for us to recognize their emotions. But there's much more to this process than that. This is according to research conducted by Dr. Leda Berio and Professor Albert Newen from the Institute of.....»»
Key gene discovered for regulating rice grain length
Recently, a research team led by Professor Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, discovered a key gene that can influence rice grain length by regulating cell proliferation, the RGL2 gene. This pr.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»

Tim Cook’s Apple Pencil Pro for creative design inspiration. Since the 1970s, NHL goalies have used customized masks as a form of expression. This year, creators of hockey masks the top goaltenders in the league have leveraged the power of the i.....»»
Study identifies compounds that extend longevity of Japanese morning glory flowers
The longevity of plant flowers is controlled by genetically programmed mechanisms. After a certain amount of time after flowering, the expression of genes associated with programmed cell death is induced and cellular components such as proteins and n.....»»
LEGO-inspired RNA sensors enable customizable gene control
A research team has developed an RNA-based sensor platform that can regulate gene expression in bacteria. Their findings were recently featured in the journal Advanced Science......»»
New method quantifies single-cell data"s risk of private information leakage
Access to publicly available human single-cell gene expression datasets, or scRNA-seq datasets, has significantly enhanced researchers' understanding of both complex biological systems and the etymology of various diseases. However, the increase in a.....»»
Do coyotes have puppy dog eyes? New study reveals wild canines share dog"s famous expression
New research from Baylor University reveals that coyotes, like domestic dogs, have the ability to produce the famous "puppy dog eyes" expression. The study—"Coyotes can do 'puppy dog eyes' too: Comparing interspecific variation in Canis facial expr.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Study shows cholesterol enhances exosome-mediated RNA drug delivery
RNA interference (RNAi) technology has gradually become a cutting-edge technology for treating diseases such as genetic disorders and cancer due to its huge potential in gene expression regulation. However, the efficient delivery and safety of short.....»»
Team develops gene editing strategy for macroalgae Neopyropia
