Study predicts where new coronaviruses might come from

The potential scale of novel coronavirus generation in wild and domesticated animals may have been highly underappreciated, suggests new University of Liverpool research.

Published in Nature Communications, the machine-learning study identifies mammals that are potential sources for generating new coronaviruses, including species implicated in previous outbreaks (such as horseshoe bats, palm civets and pangolins) and some novel candidates.

Predicting which animals could potentially be the source of a future coronavirus outbreak may guide approaches to reduce the risk of coronavirus emergence in animals and spill-over to human populations.

“New coronaviruses can emerge when two

Microplastic in aquatic systems | Technology Org

We live in the Plastic Era. Synthetic materials are almost everywhere. They can be found in medicine, pharmacy, automotive industry, cosmetics, and even in food. Slowly plastics became our “natural everyday environment.” Why?

Synthetic materials are lighter than glass, so it became the most common packaging material. Unfortunately, plastic is used in larger amounts than recycled due to human activity, making it easier for the environment. The ocean is full of this material also in the microplastic form. Once it gets to the aquatic systems, it stays there for a long time and affects living organisms. To some extent, it

Simple and Innovative Technology to Reduce NOx in Exhaust Gas from Internal Combustion Engine

NineSigma, representing a major automotive manufacturer, seeks innovative technology to reduce nitrogen oxides (NOx) emitted in the exhaust gas.

NOx reduction in an oxygen-rich environment is assumed for the technology, targeting, for example, diesel engine exhaust and gas emission from a lean-burn gasoline engine. Proposals of higher-performance or simpler, lower-cost technology than existing selective catalytic reduction (SCR) catalysts or lean NOx trap (LNT) catalysts are awaited.

Titanium and ultraviolet light powerful combination against SARS-CoV-2 virus

Research to control and mitigate SARS-CoV-2 particles that linger on surfaces has shown that titanium oxide coated materials subjected to ultraviolent light can be highly effective in killing the virus, according to a study at the University of Nevada, Reno.

“Our work indicates that surfaces protected with a well-known photoresponsive oxide coating serve as effective deterrent to the proliferation of COVID-19 surrogates,” Ravi Subramanian, a chemical and material science engineering associate professor developing the new technology at the University, said. “We use a relatively common material called titanium dioxide (found in some toothpastes for example), but prepared in the form

Value of Distributed Energy Resources Largely Depends on Three Things: Location, Location, Location

As solar panels cover more rooftops, and buildings with load controls and storage provide more grid services, understanding the value of distributed energy resources (DERs) is increasingly important. Yet few utilities and states consider their value at specific points on the electric system in planning, procurement, and design of DER programs and rates.

Nanowire could provide a stable, easy-to-make superconducting transistor

Superconductors — materials that conduct electricity without resistance — are remarkable. They provide a macroscopic glimpse into quantum phenomena, which are usually observable only at the atomic level. Beyond their physical peculiarity, superconductors are also useful. They’re found in medical imaging, quantum computers, and cameras used with telescopes.

But superconducting devices can be finicky. Often, they’re expensive to manufacture and prone to err from environmental noise. That could change, thanks to research from Karl Berggren’s group in the Department of Electrical Engineering and Computer Science.

MIT researchers are developing a superconducting nanowire, which could enable more efficient superconducting electronics. Image
