Are Cats Spreading COVID-19? Study Finds Domestic Cats Can Be Asymptomatic Carriers of SARS-CoV-2

Are Cats Spreading COVID-19? Study Finds Domestic Cats Can Be Asymptomatic Carriers of SARS-CoV-2

Two recently published studies from Kansas State University researchers and collaborators have led to two important findings related to the pandemic: Domestic cats can be asymptomatic carriers of , but pigs are unlikely to be significant carriers of the virus. SARS-CoV-2 is the coronavirus responsible for COVID-19.Cats can spread SARS-CoV-2 efficiently to other cats within two days. Further research is needed to study whether domestic cats can spread the virus to other animals and humans.“Other research has shown that COVID-19-infected human patients are transmitting SARS-CoV-2 to cats;...

Decades Old Mystery Solved: A “New Kind of Electrons”

Decades Old Mystery Solved: A “New Kind of Electrons”

Why do certain materials emit electrons with a very specific energy? This has been a mystery for decades — scientists at TU Wien have found an answer.It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called “photoelectrons.” In materials research, so-called “Auger electrons” also play an important role — they can be emitted by atoms if an electron is first removed from one of the inner electron shells. But now scientists at TU Wien...

New Kind of Superconductivity Discovered: Researchers Demonstrate a Superconductor Previously Thought Impossible

New Kind of Superconductivity Discovered: Researchers Demonstrate a Superconductor Previously Thought Impossible

Superconductivity is a phenomenon where an electric circuit loses its resistance and becomes extremely efficient under certain conditions. There are different ways in which this can happen which were thought to be incompatible. For the first time, researchers discover a bridge between two of these methods to achieve superconductivity. This new knowledge could lead to a more general understanding of the phenomena, and one day to applications.If you’re like most people, there are three states of matter in your everyday life: solid, liquid, and gas. You might be familiar with a fourth state of...

Scientists Find New Way of Cooking Rice That Removes Arsenic and Retains Nutrients

Scientists Find New Way of Cooking Rice That Removes Arsenic and Retains Nutrients

A new paper, published on October 29, 2020, in Science of the Total Environment shows that cooking rice in a certain way removes over 50 percent of the naturally occurring arsenic in brown rice, and 74 percent in white rice. Importantly, this new method does not reduce micronutrients in the rice.Following previous research from the University of Sheffield that found half of the rice consumed in the UK exceeded European Commission regulations for levels of arsenic in rice meant for the consumption for infants or young children.This new study tested different ways to cook rice to try and...

Solar Cells of the Future: System for Increasing the Efficiency of Organic Solar Cells

Solar Cells of the Future: System for Increasing the Efficiency of Organic Solar Cells

Organic solar cells are cheaper to produce and more flexible than their counterparts made of crystalline silicon, but do not offer the same level of efficiency or stability. A group of researchers led by Prof. Christoph Brabec, Director of the Institute of Materials for Electronics and Energy Technology (i-MEET) at the Chair of Materials Science and Engineering at FAU, have been working on improving these properties for several years. During his doctoral thesis, Andrej Classen, who is a young researcher at FAU, demonstrated that efficiency can be increased using luminescent acceptor...

A New Way to Synthesize Hydrocarbons Could Reduce Dioxide Emissions and Slash Costs of Chemical Manufacturing

Illustration of a novel room-temperature process to remove carbon dioxide (CO2) by converting the molecule into carbon monoxide (CO). Instead of using heat, the nanoscale method relies on the energy from surface plasmons (violet hue) that are excited when a beam of electrons (vertical beam) strikes aluminum nanoparticles resting on graphite, a crystalline form of carbon. In the presence of the graphite, aided by the energy derived from the plasmons, carbon dioxide molecules (black dot bonded to two red dots) are converted to carbon monoxide (black dot bonded to one red dot.

New Battery Technology Enables Charging Electric Cars Up to 90% in Just 6 Minutes

With Telsa in the lead, the electric vehicle market is growing around the world. Unlike conventional cars that use internal combustion engines, electric cars are solely powered by lithium ion batteries, so the battery performance defines the car’s overall performance. However, slow charging times and weak power are still barriers to be overcome. In light of this, a POSTECH research team has recently developed a faster charging and longer lasting battery material for electric cars.The research teams of Professor Byoungwoo Kang and Dr. Minkyung Kim of the Department of Materials Science and...
