A team of NYU chemists has created self-assembled, three-dimensional DNA crystals that can bind a separate, dye-bearing strand—a breakthrough that enhances the functionality of these tiny building blocks.
Results of tests provide evidence that exposure to a chemical mixture can disturb thyroid hormone signalling. The authors say that this adds weight to the suggestion that similar exposures can adversely affect brain development in unborn children.
Los Alamos National Laboratory Fellow Jaqueline Kiplinger was recognized this week with the International Union of Pure and Applied Chemistry (IUPAC) 2017 Distinguished Women in Chemistry or Chemical Engineering award. Kiplinger was one of 12 women recognized this year internationally and the only recipient of this honor from the United States.
Researchers at Los Alamos National Laboratory in collaboration with the University of California – Irvine (UCI) have uncovered a significant new chemical attribute of plutonium, the identification and structural verification of the +2 oxidation state in a molecular system.
Learning and memory depend on cells' ability to strengthen and weaken circuits in the brain. Now, researchers at Johns Hopkins Medicine report that a protein involved in recycling other cell proteins plays an important role in this process.
Researchers have reversed depression symptoms in mice simply by feeding them a probiotic bacteria found in yogurt. They also discovered a specific mechanism for how the bacteria affect mood, providing a direct link between gut health and mental health.
Researchers at Columbia University Medical Center discovered that lipocalin 2, a hormone secreted by bone cells, suppresses appetite in mice. The study findings, which reveal a new mechanism for regulating food intake and blood sugar, could lead to the development of new treatments for obesity, type 2 diabetes, and other metabolic disorders.
When a team led by the Department of Energy's Oak Ridge National Laboratory tried to verify that shrinking the nanoparticle size would adversely affect the mechanical properties of polymer nanocomposites, they got a big surprise.
An international research team centered at Indiana University have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide -- a carbon-neutral fuel source -- more efficiently than any other method of "carbon reduction." The discovery, reported today in the Journal of the American Chemical Society, is a new milestone in the quest to recycle carbon dioxide in the Earth’s atmosphere into carbon-neutral fuels and others materials.
Scientists at Argonne have invented a new foam, called Oleo Sponge, that not only easily adsorbs spilled oil from water, but is also reusable and can pull dispersed oil from the entire water column—not just the surface.
An international collaboration of computational physicists and chemists have shed new light on how the polymer structure bears on the glass-transition temperature in the forming of glass in atactic polystyrene (PS), a commonly used glass substance. Their work is reported this week in The Journal of Chemical Physics.
Carbonate, bicarbonate, and carbonic acid emerge when atmospheric carbon dioxide dissolves in the oceans, which is the largest sink for this greenhouse gas. Researchers are interested in better understanding the carbonate system to potentially help facilitate carbon sequestration schemes, to help mitigate climate change. Recently, researchers made breakthrough discoveries about the carbonate species’ behavior at saltwater surfaces, like that of the ocean. They report their findings this week in The Journal of Chemical Physics.
For most people, the drip, drip, drip of a leaking faucet would be an annoyance. But for Georgia Institute of Technology Ph.D. candidate Alexandros Fragkopoulos, what happens inside droplets is the stuff of serious science.
Graduate student has found some synthetic chemicals in greater concentrations than many other pollutants, including the previously banned flame retardants.
A rise in caloric consumption combined with a decrease in physical activity has contributed to a boom of metabolic diseases, such as type 2 diabetes mellitus and cardiovascular diseases (e.g., heart failure and stroke).
Under a collaborative partnership between the National Aeronautics and Space Administration and the Department of Energy, a new automated measurement system developed at DOE’s Oak Ridge National Laboratory will ensure quality production of plutonium-238 while reducing handling by workers.
The U.S. Department of Energy’s Office of Fossil Energy has awarded Southern Research nearly $800,000 for a project that targets a more cost-efficient and environmentally friendly method of producing some of the most important chemicals used in manufacturing.
Despite its omnipresence, water has many physical properties that are still not completely understood by the scientific community. One of the most puzzling relates to the activity of water molecules after they undergo a process called “supercooling.” Now, new findings from Roma Tre University, in Rome, Italy, on the interactions of water molecules under these exotic conditions appear this week in The Journal of Chemical Physics.
scientists at the Department of Energy's Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory, Brookhaven National Laboratory, and other institutes designed a new assembly-line system that rapidly replaces exposed biological samples by moving droplets along a miniature conveyor belt, timed to coincide with the arrival of the X-ray pulses. The droplet-on-tape system now allows the team to study the biochemical reactions in real-time from microseconds to seconds, revealing the stages of these complex reactions.
