An undergraduate leads the discovery of a way to synthesize a rare molecule drawn from poppies. The molecule could become a building block for painkillers and other drugs......»»
Researchers develop new, more accurate computational tool for long-read RNA sequencing
On the journey from gene to protein, a nascent RNA molecule can be cut and joined, or spliced, in different ways before being translated into a protein. This process, known as alternative splicing, allows a single gene to encode several different pro.....»»
In a first, chemists synthesize ocean-based molecule that could fight Parkinson"s
Organic chemists at UCLA have created the first synthetic version of a molecule recently discovered in a sea sponge that may have therapeutic benefits for Parkinson's disease and similar disorders. The molecule, known as lissodendoric acid A, appears.....»»
Squid tissues and chemistry combine for versatile hydrogels
Researchers at Hokkaido University in Japan have combined natural squid tissues with synthetic polymers to develop a strong and versatile hydrogel that mimics many of the unique properties of biological tissues. Hydrogels are polymer networks contain.....»»
The effects of tightening a molecular knot
A study conducted by Anne-Sophie Duwez and Damien Sluysmans from the NANOCHEM group at the University of Liège (Belgium) has made it possible to decode the mechanical response of small-molecule synthetic overhand knots by single-molecule pulling exp.....»»
Novel synthesis process for sustainable production of small molecules
Researchers at Ruhr University Bochum, Germany, have discovered a new synthetic pathway with which they can produce a specific organic compound from the simple molecule carbon monoxide (CO), namely anionic ketenes. These were previously only known as.....»»

How the science behind epidemics helped physicists develop state-of-the-art conductive paint
In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation'—a m.....»»
New fluorescent sensor reveals a key protein involved in interactions between cells
Researchers led by Osaka University report the development of INCIDER, a fluorescent sensor system that enables high-contrast microscopic imaging of temporal changes in cellular interactions mediated by the N-cadherin molecule. This sensor system, wh.....»»
Dough (formerly Eve) now has its own 27-inch 240Hz OLED gaming monitor
The brand Dough has introduced a new OLED gaming monitor with a new technology with individually lit pixels that mimics having 3,686,400 backlight dimming zones......»»
Deal with sophisticated bot attacks: Learn, adapt, improve
A computer program known as a “bot” acts as an agent for a user or another program or mimics human action. Bots are typically used to automate particular tasks so they can be used without specific human instructions. In this Help Net Secu.....»»
Measuring times in billionths of a billionth of a second
How fast do electrons inside a molecule move? Well, it is so fast that it takes them just a few attoseconds (a billionth of billionth of a second) to jump from one atom to another. Blink and you missed it—millions of billions of times. So measuring.....»»
Can a new technique for capturing "hot" electrons make solar cells more efficient?
A new way of extracting quantitative information from state-of-the-art single molecule experiments has been developed by physicists at the University of Bath. Using this quantitative information, the researchers will be able to probe the ultra-fast p.....»»
What does Polly say? Community science data reveal species differences in vocal learning by parrots
While most animals don't learn their vocalizations, everyone knows that parrots do—they are excellent mimics of human speech. But how large is the vocabulary of different parrot species? Do males "talk" more than females? Does a parrot's vocabulary.....»»
Researchers solve 20-year-old optical light mystery
It was believed that it was impossible to differentiate the enantiomers of a chiral molecule using helical light beams—until now that is, thanks to a group of uOttawa researchers......»»
Method predicts accurate stereochemistry of pericyclic reactions using only target molecule structure
Researchers at the Institute for Chemical Reaction Design and Discovery (WPI-ICReDD) have demonstrated the expanded use of a computational method called the artificial-force-induced reaction (AFIR) method, predicting pericyclic reactions with accurat.....»»
Scientists develop novel mode of linear hybridization chain reaction
Hybridization chain reaction refers to an enzyme-free nucleic acid polymerization reaction. A target molecule triggers cascade hybridization reactions by several thermodynamically stable DNA fuel strands, producing ultra-long DNA nanostructures with.....»»
