Researchers from Tokyo Metropolitan University and RIKEN CSRS have developed a new analytical platform based on liquid chromatography, mass spectrometry and software analysis that quantifies the structure of messenger RNA (mRNA) based medicines.
The relentless neurological disease amyotrophic lateral sclerosis (ALS) eventually shuts down the entire body, but the devastation starts at a molecular level. The possibility of stopping the disease by repairing and preserving proteins in the brain has inspired experiments in the lab of Meredith Jackrel, an assistant professor of chemistry in Arts & Sciences at Washington University in St. Louis.
The origin of life is one of the great questions of mankind. One of the prerequisites for the emergence of life is the abiotic - not by living beings caused chemical - production and polymerization of amino acids, the building blocks of life.
The study is part of the “THz calorimetry“ project, which received a European Research Council (ERC) Advanced Grant. “The visionary idea in the project was to combine two powerful techniques in Physical Chemistry – laser spectroscopy and calorimetry,“ explains the grantee, Martina Havenith.
When it comes to DNA, one pesky mosquito turns out to be a rebel among species.
Climate change is a global environmental concern. A major contribution to climate change comes from excessive burning of fossil fuels.
Lithium-ion batteries have remained unrivaled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations.
Some “broken” nanomachines better sense their environment while others gain the ability to control their activity over time, Canadian researchers at Université de Montréal find.
Oak Ridge National Laboratory Weinberg Fellow Addis Fuhr uses quantum chemistry and machine learning methods to advance new materials.
Scientists at St. Jude Children’s Research Hospital used deep sequencing data from childhood cancer survivors and found the mutational fingerprint of a toxic chemotherapy associated with a marker of accelerated aging.
Devices currently in development that clean up dirty water using sunlight can only produce a few gallons of water each day. But now, researchers in ACS Central Science report how a sunlight-powered porous hydrogel could potentially purify enough water to meet daily needs — even when it’s cloudy.
Reactive oxygen species (ROS) are reputed for their involvement in carcinogenesis.
Discover BMB, the annual meeting of the American Society for Biochemistry and Molecular Biology, will feature award lectures by high-profile speakers discussing noteworthy research, education and diversity initiatives. The meeting will take place March 25–28 in Seattle.
Until now, it has been clear: you can have a metal or a plastic, but not both in one. However, things don’t have to stay that way. In the journal Angewandte Chemie, a Chinese research team has now reported a polymer with a metallic backbone that is conductive, thermally stable, and has interesting optoelectronic properties.
Scientists at the University of Portsmouth are to develop ‘plastic-eating’ enzymes that could help solve the ever-growing problem of waste polyester clothing.

A collaboration between scientists at Cambridge and UCL has led to the discovery of a new form of ice that more closely resembles liquid water than any other and may hold the key to understanding this most famous of liquids.
Chemists can make a career out of controlling whether certain molecules are generated as a lefty or a righty. Molecules don’t literally have hands, but scientists often refer to them in this way when looking at molecules that are mirror images of each other and therefore are not superimposable.
