Princeton Chemistry's Scholes Group is reporting evidence that quantum vibrations participate in electron transfer, establishing with ultrafast laser spectroscopy that the vibrations provide channels through which the reaction takes place.
Seeking to establish an experimental proof for a highly contested topic - the role of vibrations in processes fundamental to solar energy conversion - Princeton researchers set out to map the progress of a photoinduced electron transfer (ET) reaction.
'Tis the season to be grateful, even for your boss, according to a recent University of Central Florida study that suggests when supervisors feel appreciated, it gives them a boost of energy and optimism. In the end, that's good for employees and the organization's bottom line.
AMES, Iowa - The foods we eat may have a direct impact on our cognitive acuity in our later years. This is the key finding of an Iowa State University research study spotlighted in an article published in the November 2020 issue of the Journal of Alzheimer's Disease.
Philadelphia, December 10, 2020 - Researchers at Memorial Sloan Kettering Cancer Center (MSK) have found that SARS-CoV-2 genetic material can be reliably detected in self-collected saliva samples at a rate similar to that of nasopharyngeal and oropharyngeal swabs.
BELLINGHAM, Washington, USA — As part of the opening plenary session at the SPIE Astronomical Telescopes + Instrumentation Digital Forum, Hitoshi Kuninaka, of the Japan Aerospace Exploration Agency, will be discussing and responding to audience questions about the successful return of the Hayabusa2 capsule from its asteroid-sample mission, a second-time-in-history-su
Scientists may have discovered a new ally in efforts to keep coastal communities in the Pacific Northwest safe from future tsunamis, according to a new study: Fleets of commercial shipping vessels.
The research taps into an urgent need for communities like Newport, Oregon, a seaside town that is home to more than 10,000 people. If a tsunami formed along a fault line in the Pacific called the Cascadia Subduction Zone, residents there might have just minutes to get to safety, said study coauthor Anne Sheehan.
CLEVELAND -- A new paper published in the New England Journal of Medicine Catalyst states that the U.S. health care system spends in excess of $1.3 trillion annually on sub-optimal behavior and outlines a roadmap for reducing costs by eliminating defects in health care value. The paper, entitled Making a Dent in the Trillion-Dollar Problem: Toward Zero Defects, can be found here: https://catalyst.nejm.org/doi/full/10.1056/CAT.19.1064.
BOSTON - The antiepileptic drug ezogabine reduced pathologic excitability of cortical and spinal motor neuron cells that are early signs of clinical dysfunction in people with amyotrophic lateral sclerosis (ALS), according to a study conducted by the Neurological Clinical Research Institute of Massachusetts General Hospital (MGH).
Researchers at UC Santa Cruz have developed a novel serological assay for the detection of antibodies to SARS-CoV-2, the coronavirus that causes COVID-19.
Rebecca DuBois, associate professor of biomolecular engineering at UC Santa Cruz, said the new method her team developed is as accurate as the most reliable antibody tests currently available, but is less complex and can be performed much faster.
Blowing air from a fan into the face of patients with advanced cancer experiencing breathlessness, and other nonpharmacologic interventions, may offer symptom relief, according to new research directed by Johns Hopkins Kimmel Cancer Center investigators. On the other hand, the investigators found medications, such as opioids, had limited impact in improving breathlessness.
Scientists around the world are working to develop electronic skins that attach to the body and monitor vital signs. These E-skins need to be comfortable, breathable, and flexible for everyday use. Gold is typically used to fabricate the electrodes that conduct electric signals in these applications. But gold is expensive, involves a complicated manufacturing process, and must be sterilized for use on the human body.
The use of plastic mulch (plastic covering on crop lines) is a widespread technique used in agricultural regions in order to increase the profitability of the crops. According to the European Commission, 100,000 tonnes of plastic mulch was used per year in the European Union in 2016. Taking these figures into account and the fact that after the harvest some plastic usually remains in the soil, the accumulation of plastic in territories of intensive agriculture is an environmental problem that is of concern in the sector and also for the public administrations.
This novel method was the first to detect conformational changes in the protein TDP-43 in the patients' CSF. The project team headed by Professor Klaus Gerwert and Professor Lars Tönges published their research results in the international journal Annals of Clinical and Translational Neurology from 3 December 2020.
Altered protein structures in ALS
Perovskites are materials made up of organic compounds bound to a metal. Propelled into the forefront of materials' research because of their structure and properties, perovskites are earmarked for a wide range of applications, including in solar cells, LED lights, lasers, and photodetectors.
Researchers from Skoltech and their colleagues have built two models that accurately explain the light-emitting behavior of semiconductor nanoplatelets, minuscule structures that can become the building blocks for optoelectronics of the future. The paper was published in the journal Physical Chemistry Chemical Physics.
