Coughing downward reduces spread of respiratory droplets: study

With many people heading indoors for the winter months and respiratory droplets acting as a major contributor to COVID-19 spread, the scientific community has renewed interest in the dynamics behind how they spread. Modeling ...

Computer simulation models potential asteroid collisions

An asteroid impact can be enough to ruin anyone's day, but several small factors can make the difference between an out-of-this-world story and total annihilation. In AIP Advances, a researcher from the National Institute ...

How plasma technology can safely clean disposable PPE for reuse

A new study from the University of Southampton has demonstrated a new method to safely clean and reuse facemask respirators with advanced low-temperature plasma technology. The discovery could help future pandemic responses ...

Amount of information in visible universe quantified

Researchers have long suspected a connection between information and the physical universe, with various paradoxes and thought experiments used to explore how or why information could be encoded in physical matter. The digital ...

Challenging the big bang puzzle of heavy elements

It has long been theorized that hydrogen, helium, and lithium were the only chemical elements in existence during the Big Bang when the universe formed, and that supernova explosions, stars exploding at the end of their lifetime, ...

Energy harvesting technology based on ferromagnetic resonance

Researchers from the Graduate School of Engineering, Osaka City University have succeeded in storing electricity with the voltage generated from the conversion phenomenon of ferromagnetic resonance (FMR) using an ultra-thin ...

Probing deeper into origins of cosmic rays

Cosmic rays are high-energy atomic particles continually bombarding Earth's surface at nearly the speed of light. Our planet's magnetic field shields the surface from most of the radiation generated by these particles. Still, ...

DNA origami enables fabricating superconducting nanowires

The quest for ever-smaller electronic components led an international group of researchers to explore using molecular building blocks to create them. DNA is able to self-assemble into arbitrary structures, but the challenge ...
