Scientists develop approach to synthesize unconventional nanoalloys for electrocatalytic application
Metallic alloys at nanometer scale (nanoalloys) have great potentials in electrocatalysis. The interaction among different components in nanoalloys may modify the electronic configurations of active metals and generate synergistic effects, boosting their performance in terms of activity, durability and selectivity in electrocatalytic reactions.
One in four older Americans had a virtual medical visit in the first three months of the COVID-19 pandemic, most of them by video, a new telehealth poll finds. That's much higher than the 4% of people over 50 who said they had ever had a virtual visit with a doctor in a similar poll taken in 2019.
COMPUTER SCIENCE Researchers from the University of Copenhagen and the Technical University of Denmark (DTU) thought that they were five years away from solving a math riddle from the 1980's. In reality, and without knowing, they had nearly cracked the problem and had just given away much of the solution in a research article. The solution could be used to improve tomorrow's phones and computers.

New research from the University of Southampton has successful discovered a way to bind two negatively charged electron-like particles which could create opportunities to form novel materials for use in new technological developments.
Positive and negative electric charges attract each other, forming atoms, molecules, and all that we usually refer as matter. However, negative charges repel each other, and in order to form atom-like bound objects some extra glue is needed to compensate this electrostatic repulsion and bind the particles together.
Environmental conditions such as sea surface temperature and the occurrence of cold water upwelling events drive the structure of interaction networks in marine intertidal communities via their effects on species richness, according to new research.
EVANSTON, Ill. -- Northwestern University researchers have combined climate modeling with public health data to evaluate the impact of electric vehicles (EVs) on U.S. lives and the economy.
A new study found that if EVs replaced 25% of combustion-engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. In more aggressive scenarios -- replacing 75% of cars with EVs and increasing renewable energy generation -- savings could reach as much as $70 billion annually.
Thomas Brück saw the sea whip Antillogorgia elisabethae for the first time 17 years ago while diving on a research trip to the Bahamas. He still remembers this encounter vividly, which took place 18 meters below the water's surface: "Their polyp-covered, violet branchlets moved gently in the current. A fascinating living organism!" As it also contains various biologically active compounds, the biochemist since then has studied the natural product biosynthesis of this soft coral.
STONY BROOK, NY, August 17, 2020 - A team of international physicists including Jennifer Cano, PhD, of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator conducting current without dissipation and lost energy. The finding, detailed in a paper published in Nature Physics, could be the basis of research leading to new, better energy efficient electrical conductors.
Running into an unseen spiderweb in the woods can be scary enough, but what if you had to worry about a spiderweb - and the spider - being catapulted at you? That's what happens to insects in the Amazon rain forests of Peru, where a tiny slingshot spider launches a web - and itself - to catch unsuspecting flies and mosquitoes.
NASA's Terra satellite provided a visible image of the end of Post-tropical Storm Kyle in the North Atlantic Ocean on Aug. 16.
Kyle was a tropical storm for only one day, when it formed a couple of hundred miles off the coast of Rhode Island on Aug. 15. The next day, Aug. 16, Kyle had become a post-tropical storm.
URBANA, Ill. - When engineers develop drinking water systems, they often expect their technology and expertise to work in any context. But project success depends as much on the people and place as on technical design, says Ann-Perry Witmer, lecturer in the Department of Agricultural and Biological Engineering (ABE) and research scientist at the Applied Research Institute at University of Illinois.
Cancer immunotherapy -- empowering a patient's own immune system to clear away tumors on its own -- holds great promise for some patients. But for other patients, immunotherapy just doesn't work.
Researchers at University of California San Diego School of Medicine have found evidence that helps explain why patients who are young and/or female have especially low response rates to some types of cancer immunotherapy.
A small but evolving dent in Earth's magnetic field can cause big headaches for satellites.
CORVALLIS, Ore. - Regenerative ranching, a holistic approach to managing grazing lands, enhances ranchers' adaptive capacity and socioeconomic well-being while also providing an opportunity to mitigate climate change, a new study from Oregon State University has found.
Regenerative ranching practices rebuild ecological processes, allowing ranchers to reduce reliance on products such as chemical herbicides, pesticides and fertilizers, which are significant sources of greenhouse gas emissions.
What do we mean by the word beautiful? It depends not only on whom you ask, but in what language you ask them. According to a machine learning analysis of dozens of languages conducted at Princeton University, the meaning of words does not necessarily refer to an intrinsic, essential constant. Instead, it is significantly shaped by culture, history and geography. This finding held true even for some concepts that would seem to be universal, such as emotions, landscape features and body parts.
