Structural insight into process of gene regulation
In the cell nucleus, numerous proteins bind to the DNA molecule in order to regulate the activity of certain genes. One of these is the TATA-box binding protein (TBP), which binds to a specific DNA sequence and constitutes an initial signal for the r.....»»
Defect-rich MnOx nanobelts prepared for glutathione detection in recent study
A recent study published in Sensors and Actuators: B. Chemical highlights the development of highly active oxidase mimics using MnOx nanobelts (NBs) generated through laser irradiation in liquid (LIL) techniques by researchers from Institute of Solid.....»»
A fast and efficient method for detecting microRNAs
In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs (miRNAs), which are now known to be present across.....»»
On-demand preparation of organosilicon reagents
National University of Singapore (NUS) scientists have demonstrated that stepwise customized functionalization of multihydrosilanes to access fully substituted silicon compounds can be realized using neutral eosin Y, an inexpensive dye molecule......»»

Scientists discover a way Earth"s atmosphere cleans itself
Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere......»»
A new quantum approach to solve electronic structures of complex materials
If you know the atoms that compose a particular molecule or solid material, the interactions between those atoms can be determined computationally, by solving quantum mechanical equations—at least, if the molecule is small and simple. However, solv.....»»
Video: Repeat expansion disorders—how RNA may gum up the works
What happens when an RNA molecule contains too many repeats of the same short sequence of bases, or RNA building blocks?.....»»
Researchers discover a way to observe chromatin interaction changes in cancer-associated genetic mutations
Studying the microbiology of any entity, be it a molecule or a dolphin, ideally means putting a spotlight as close to the source material as possible. That can be especially challenging when you're investigating the Rube Goldberg environment of a cel.....»»

The modulation of a single-molecule electron source using light
Researchers at University of Tokyo, JTS PRESTO, Ludwig Maximilians Universität and Kindai University recently demonstrated the modulation of an electron source by applying laser light to a single fullerene molecule. Their study, featured in Physical.....»»
Understanding how cohesin makes DNA loops in the human genome and its role in Cornelia de Lange syndrome
Cohesin is a ring-shaped protein that surrounds and moves around the DNA molecule, forming the loops. It is a crucial process for the cell. Understanding how cohesin works has been one of the challenges of molecular biology in recent decades. A study.....»»
Discovery of drug candidate that neutralizes SARS-CoV-2 could reduce length of infection upon exposure
The discovery of a small molecule in the research lab of Bradley McConnell, professor of pharmacology at the University of Houston College of Pharmacy, may well be the genesis of new medication which could shorten the course of the SARS-CoV-2 virus......»»
A new, sustainable source for a promising cancer killer
Plants produce all types of curious chemicals. Some deter predators. Some smell wonderful. Some even have medicinal value. One of these hidden gems is (–)-jerantinine A (JA), a molecule with remarkable anticancer properties, produced by a plant cal.....»»
Without this, plants cannot respond to temperature
UC Riverside scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair......»»
Using chemical exfoliation to produce superconducting tungsten disulfide ink
A team of chemists, engineers, material scientists and physicists from Princeton University, Rutgers University and the University of Regensburg has developed a chemical exfoliation technique to produce single-molecule-thick tungsten disulfide ink. T.....»»
New machine-learning approach identifies one molecule in a billion selectively, with graphene sensors
Graphene's 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its a.....»»
Breaking bonds: Double-helix unzipping reveals DNA physics
