NMR spectroscopy method provides faster way to determine chiral structure of molecules
Researchers from Karlsruhe Institute of Technology (KIT) and Voxalytic GmbH have developed a new method that allows, for the first time, the elucidation of the chiral structure of molecules—the exact spatial arrangement of the atoms—by nuclear ma.....»»
Shallow waters make the best carbon sinks, researchers find
Marine phytoplankton take up atmospheric carbon and carry it to the seafloor when they die and sink (a process known as organic carbon sedimentation). This biological carbon pump is a powerful part of Earth's carbon cycle, yet scientists don't have a.....»»
Social media interviews uncover New Yorkers" frustrations with high energy costs and reliability
Researchers at Columbia University Mailman School of Public Health are using a novel interview method to assess New Yorkers' perceptions and feelings related to their difficulties paying for and controlling heating and cooling in their homes. Inspire.....»»
Genetic analysis reveals new giant fanged frog species in Philippines that is nearly identical to even larger species
Researchers from the University of Kansas have published findings in the journal Ichthyology & Herpetology describing a new species of fanged frog, named Limnonectes cassiopeia, from the Philippine island of Luzon......»»
Archaeologists challenge theory of violent Steppe invasion in Iberia Peninsula
A study by the Universitat Autònoma de Barcelona (UAB) and the University of Murcia (UM) challenges the theory that warrior groups with a "Steppe" genetic component originating from Eastern Europe violently replaced the male population of the Iberia.....»»
How a failed switch won the Nobel Prize
In 2016, University of Groningen Professor of Organic Chemistry Ben Feringa and two of his colleagues were awarded the Nobel Prize in Chemistry for having created "the world's tiniest machines." Feringa had built a light-driven motor comprising one s.....»»

Zeolite catalyst method uses microwaves to convert waste cooking oil into useful chemicals
Researchers from Kyushu University have revealed that a zeolite material called Na-ZSM-5 is effective in improving the chemical conversion of biomass into olefins—a precursor chemical that makes everything from plastics to pharmaceuticals—using m.....»»
AI system identifies elephant trumpeting calls to improve safety for villagers
In an article published in the International Journal of Engineering Systems Modelling and Simulation researchers demonstrate how a trained algorithm can identify the trumpeting calls of elephants, distinguishing them from human and other animal sound.....»»
Researchers reveal performance boost mechanism in single-atom catalyst for oxygen evolution reaction
Hydrogen energy, with its green, low-carbon and high-calorific-value properties, is emerging as the new key to solving the energy crisis. Electrochemically, water splitting has garnered much attention as a promising hydrogen production technique. How.....»»
Green hydrogen: MXenes show talent as catalyst for oxygen evolution reaction
The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalized, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitti.....»»
Artemis III landing sites identified using mapping and algorithm techniques
Where would be the most ideal landing site for the Artemis III crew in SpaceX's Human Landing System (HLS)? This is what a recent study submitted to Acta Astronautica, and available on the arXiv preprint server, hopes to address as an international t.....»»

Uncovering the unique roles of Exportin-5 in RNA export within Drosophila cells
Eukaryotic cells are complex biological units, each with multiple membrane-bound compartments. These cells use specialized mechanisms to export biomolecules from their synthesis site to where they function......»»
Theoretical model for multisite alloy catalyst design quantifies active site contributions
Two research teams have developed a novel theoretical model to describe the overall activity of multisite alloy catalysts. In their study published in Journal of the American Chemical Society, they propose a concept of equivalent site ratio and succe.....»»
Glitch in protein synthesis could affect tumor growth
During protein synthesis, or translation, genetic information transcribed in the cell's mRNA directs the stringing together of amino acids—the building blocks of proteins. As the translation machinery carouses along the string of nucleotides that m.....»»

Solving the side effect problem of siRNA drugs for genetic disease treatment
Small interfering RNA (siRNA) drugs are a class of therapeutic agents that silence specific genes associated with inherited diseases. However, siRNA drugs have challenges because siRNAs often silence genes other than the target ones, causing side eff.....»»
Global study shows demersal fishing affects ocean floor carbon storage
Scientists are growing increasingly concerned about the impact demersal fishing is having on climate change and the preservation of organic carbon stored in the seabed......»»
Angiosperms study provides insights into genome evolution after whole-genome duplications
Whole-genome duplication (WGD, or polyploidy) is a common and frequent occurrence in plants, providing raw genetic material for evolution. Homoeologs (duplicate genes from a WGD) often diverge in expression levels, while some still maintain similar (.....»»
