DDT pollutants found in deep sea fish off LA coast raise questions about the pesticide"s continuing threat to wildlife
In the 1940s and 1950s, the ocean off the coast of Los Angeles was a dumping ground for the nation's largest manufacturer of the pesticide DDT—a chemical now known to harm humans and wildlife. Due to the stubborn chemistry of DDT and its toxic brea.....»»
Attosecond core-level spectroscopy reveals real-time molecular dynamics
Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxati.....»»
Cold sintering may rescue plastic, ceramics, battery components from landfills
Recycling does not necessarily prevent an item from eventually ending up in a landfill, according to Enrique Gomez, interim associate dean for equity and inclusion and professor of chemical engineering in the Penn State College of Engineering. Instea.....»»
Lake tsunamis pose significant threat under warming climate
Cowee Creek, Brabazon Range, Upper Pederson Lagoon—they mark the sites of recent lake tsunamis, a phenomenon that is increasingly common in Alaska, British Columbia and other regions with mountain glaciers......»»
New Nevada experiments aim to improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear e.....»»
Novel chemical tool for understanding membrane remodeling in the cell
In a study published in Proceedings of the National Academy of Sciences, Umeå researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell......»»
Researchers make a plastic that includes bacteria that can digest it
Bacterial spores strengthen the plastic, then revive to digest it in landfills. Enlarge (credit: Han Sol Kim) One reason plastic waste persists in the environment is because there's not much that can eat it. The chemical.....»»
Organic electrochemical transistors: Scientists solve chemical mystery at the interface of biology and technology
Researchers who want to bridge the divide between biology and technology spend a lot of time thinking about translating between the two different "languages" of those realms......»»
First high-resolution 3D nanoscale chemical imaging achieved with multi-modal tomography
By exploiting a smart learning algorithm that fuses two microscopy signals, University of Michigan researchers have accomplished high-resolution, efficient 3D chemical imaging for the first time at the one-nanometer scale. For context, a nanometer is.....»»
Scientists" research on RNA editing illuminates possible lifesaving treatments for genetic diseases
A team at Montana State University published research this month that shows how RNA, the close chemical cousin to DNA, can be edited using CRISPRs. The work reveals a new process in human cells that has potential for treating a wide variety of geneti.....»»
Scientists discover safer alternative for an explosive reaction used for more than 100 years
The chemical industry has been using a reaction with explosive chemicals for more than 100 years—now Mülheim scientists have discovered a safer alternative. The Ritter Group of the Max Planck Institut für Kohlenforschung in Mülheim/Ruhr has publ.....»»
Recovering phosphorus from sewage sludge ash to address problem of diminishing supplies of phosphorus ores
Valuable supplies of phosphorus could be recovered from sewage sludge ash, which remains after the sludge has been burned for electric power generation. The method has been developed by chemical engineers Yuuki Mochizuki and Naoto Tsubouchi at Hokkai.....»»
Synthesis of two new carbides provides perspective on how complex carbon structures could exist on other planets
Researchers at the University of Bayreuth have gained new insights in the field of high-pressure carbon chemistry: They synthesized two new carbides—compounds of carbon and another chemical element—with unique structures. The results may provide.....»»
