Imaging the chemical fingerprints of molecules
Flip through any chemistry textbook and you'll see drawings of the chemical structure of molecules—where individual atoms are arranged in space and how they're chemically bonded to each other. For decades, chemists could only indirectly determine c.....»»
Synthetic chemistry approach yields new compounds with potential biomedical applications
Researchers at Rice University have successfully synthesized a group of natural compounds known as fusicoccanes. The molecules found in various living organisms exhibit diverse biological activities, including the ability to modulate protein-protein.....»»
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.....»»
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......»»
Physicists create an optical tweezer array of individual polyatomic molecules for the first time
A team of physicists at Harvard University has succeeded in trapping individual polyatomic molecules in optical tweezer arrays for the first time. In their paper published in the journal Nature, the group describes how they achieved their feat and th.....»»
Researchers unveil single-shot and complete polarization imaging system using metasurfaces
Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important diagnostic tool in medicine, helping practitione.....»»
NASA/JAXA"s XRISM mission captures unmatched data with just 36 pixels
At a time when phone cameras are capable of taking snapshots with millions of pixels, an instrument on the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) satellite captures revolutionary science with just 36 of them......»»
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......»»
New research reveals terahertz waves" impact on dynamics of nanoconfined water molecules
In a new discovery, researchers have revealed novel insights into the behavior of water molecules confined within nanostructures. Their study, published in Science Advances on April 24, delves into how terahertz (THz) waves influence the dynamics of.....»»
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.....»»
Laser imaging could offer early detection for at-risk artwork
Look closely at Impressionist paintings in museums compared with photos of them taken 50 years ago, and you might notice something odd: Some are losing their bright yellow hues......»»
Plant science research paves the way for deeper understanding of how the plant immune system functions
Researchers in the laboratory of Tessa Burch-Smith, Ph.D. at the Danforth Plant Science Center and the University of Tennessee, Knoxville, are conducting pioneering work to discover how plants transmit information, important molecules, and viruses be.....»»
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.....»»
A systematic review of three key sugar metabolism proteins: HXK, SnRK1 and TOR
Sugar signaling is one of the most important regulatory signals for plant growth and development, and its metabolic network contains many regulatory factors. Sugar signaling molecules regulate cellular activities and organismal development by interac.....»»
A shortcut for drug discovery: Novel method predicts on a large scale how small molecules interact with proteins
For most human proteins, there are no small molecules known to bind them chemically (so-called "ligands"). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel.....»»
