A University of Maryland School of Medicine researcher and his colleagues at the University of North Carolina Chapel Hill have unveiled the structure of DREADDs (Designer Receptors Activated by Designer Drugs) that will pave the way for creating the next generation of these tools. This step ultimately will bring them closer to an elusive goal — understanding the underpinnings of brain disorders and develop new treatments.
Researchers created a new catalyst that transforms hydrocarbons into chemicals and materials that are higher value, easier to recycle, and biodegrade in the environment. This catalyst transforms materials such as motor oil, plastics in single-use grocery bags, water or milk bottles, and their caps, and even natural gas.
Scientists from The Ohio State University have a new theory about how the building blocks of life – the many proteins, carbohydrates, lipids and nucleic acids that compose every organism on Earth – may have evolved to favor a certain kind of molecular structure.
Imidazole dipeptides (IDPs), which are abundant in meat and fish, are substances produced in the bodies of various animals, including humans, and have been reported to be effective in relieving fatigue and preventing dementia.
Physicists in the U.S. jumped a major hurdle standing in the way of the commercialization of solar cells created with halide perovskites as a lower-cost, higher-efficiency replacement for silicon when generating electricity from the sun.
Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth. When dust particles rub against each other, they can become electrified. New research shows that this electrical discharge could be the major driving force of Martian chlorine cycle.
In a potential game changer for the treatment of superbugs, a new class of antibiotics was developed that cured mice infected with bacteria deemed nearly “untreatable” in humans — and resistance to the drug was virtually undetectable.
So-called hydrated electrons play a major role in many physical, chemical and biological processes. They are not bound to an atom or molecule and are free in the solution. Since they are only ever created as an intermediate product, they are extremely short-lived.
Dopamine is best known as a neurotransmitter. What is rather unknown, however, the underwater glue used by mussels contains large amounts of L-Dopa molecules, an analog of dopamine.
The Journal of Chemical Physics and the APS Division of Chemical Physics announce Haiming Zhu as the winner of the JCP-DCP Future of Chemical Physics Lectureship in recognition of his contributions to the understanding of the photophysical properties of emerging optoelectronic materials and processes using spatio-temporal resolved ultrafast spectroscopy.
Five of the 38 cars of a Norfolk Southern Railroad train that derailed Feb. 3 near the small town of East Palestine were carrying vinyl chloride, a known human carcinogen. University of Miami experts in chemistry, public health sciences, and law weigh in on the recent chemical spill and its potential consequences.
Researchers reporting in ACS Infectious Diseases have developed a procedure that could help researchers catch up to microbes which can rapidly mutate and evade detection and treatment. Their “AutoPLP” technique designs nucleic acid probes to detect new variants quickly, accurately and easily.
Scientists are not yet clear on how the tau protein changes from a benign protein essential for normal function in our brains into the toxic neurofibrillary tangles that are a signature of Alzheimer’s and other neurodegenerative diseases.
