Identifying an elusive molecule key to combustion chemistry
Researchers at the University of Pennsylvania and Argonne National Laboratory have made the most direct observation of a key intermediate formed during the breakdown of hydrocarbons in combustion and the atmosphere. Published in Science, this evidenc.....»»
A novel quantification method for ribonucleotides, which are needed in almost all cellular processes
RNA (ribonucleic acid), which is made up of ribonucleotides, is a molecule found in all living organisms. RNA is thought to have probably preceded DNA in primordial life billions of years ago. RNA was eventually replaced by DNA as a chemically more s.....»»
Facilitating learning chemistry with conceptual modeling
A team of researchers and teachers from the University of Twente have developed a novel teaching method that uses conceptual modeling to facilitate learning and foster creativity in classrooms of chemical science and engineering students. The student.....»»
A fullerene-like molecule made entirely of metal atoms
A small team of chemists from Nankai University, Nanjing Tech University and Shanxi University, all in China, working with a colleague from Universidad San Sebastián, in Chile, has, for the first time, created a fullerene-like molecule made entirely.....»»
Combining extreme-ultraviolet light sources to resolve a quantum mechanical dissociation mechanism in oxygen molecules
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another step towards specific q.....»»
Chemists use oxygen, copper "scissors" to make cheaper drug treatments possible
Drugs to treat cancer are often very expensive to produce, resulting in high costs for the patients who need them. Thanks to pathbreaking research by UCLA chemists, led by organic chemistry professor Ohyun Kwon, the price of drug treatments for cance.....»»
Looking for lithium-bearing pegmatites
The commercial importance of lithium is ever-growing, and its production is globally dominated by lithium-cesium-tantalum (LCT) pegmatites. These are spectacular rocks featuring impressive ultra-coarse textures, but they are very elusive due to a com.....»»
Study examines how massive 2022 eruption changed stratosphere chemistry and dynamics
When the Hunga Tonga-Hunga Ha'apai volcano erupted on January 15, 2022 in the South Pacific, it produced a shock wave felt around the world and triggered tsunamis in Tonga, Fiji, New Zealand, Japan, Chile, Peru and the United States......»»
To study radioactive neptunium and plutonium, researchers establish a novel chemistry
Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium......»»
Enhancing the antimicrobial activity of silver nanoparticles against pathogens by using tea extracts
Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) have demonstrated that green tea–silver nanoparticles as a powerful tool against pathogens such as bacteria and yeast. Their work is published in Nanosca.....»»
Pushing the boundaries of eco-friendly chemical production with azaarenes
A team of pioneering researchers from the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has made a significant leap forward in the complex world of molecular chemistry......»»
Study proposes new framework to identify keystone microbial species
Microbial communities are thought to contain keystone species, which can disproportionately affect the stability of the communities, even if only present in low abundances. Identifying these keystone species can be challenging, especially in the huma.....»»
Researchers tune the speed of chirality switching
Chiral molecules can have dramatically different functional properties while sharing identical chemical formulae and almost identical structures. The molecular structure of two types of a chiral molecule—so-called enantiomers—are mirror images of.....»»
Scientists set the stage for quantum chemistry in space on NASA"s cold atom lab
For the first time in space, scientists have produced a mixture of two quantum gases made of two types of atoms. Accomplished with NASA's Cold Atom Laboratory aboard the International Space Station, the achievement marks another step toward bringing.....»»
Shedding new light on sugars, the "dark matter" of cellular biology
Scientists at Université de Montréal's Department of Chemistry have developed a new fluorogenic probe that can be used to detect and study interactions between two families of biomolecules essential to life: sugars and proteins......»»
Scientists test new method for identifying small microplastics
Microplastics, from the beads that were once commonplace in cosmetics to the weathered and broken-down remnants of trash, are now ubiquitous in marine and inland waters around the world. To date, though, scientists have struggled to identify which pl.....»»
Onboard diagnostic standardization wasn"t always guaranteed
Onboard diagnostic tools have become central to the push for more efficient combustion engine vehicles and speedier, more accurate service and repair......»»
Elusive Attenborough echidna rediscovered in Indonesia
An elusive echidna feared extinct after disappearing for six decades has been rediscovered in a remote part of Indonesia, on an expedition that also found a new kind of tree-dwelling shrimp......»»
Pioneering automated proteoform imaging
Investigators led by Neil Kelleher, Ph.D., professor of Medicine in the Division of Hematology and Oncology and of Biochemistry and Molecular Genetics, have developed an automated technique for imaging and identifying proteoforms in ovarian cancer ti.....»»
Russia Blocks 167 VPNs, Steps Up OpenVPN & WireGuard Disruption
The head of the Russian department responsible for identifying threats to the "stability, security and integrity" of the internet, has revealed the extent of the Kremlin's VPN crackdown. Former FSO officer Sergei Khutortsev, a central figure in Russi.....»»
How animals get their stripes and spots
Nature has no shortage of patterns, from spots on leopards to stripes on zebras and hexagons on boxfish. But a full explanation for how these patterns form has remained elusive......»»
