FAYETTEVILLE, Ark. – A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current. “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors,” said Paul Thibado, professor of physics and lead researcher in the discovery.The findings, titled "Fluctuation-induced current from freestanding graphene," and published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene — a single...

Face Masks Might Actually Increase Infection Risk for COVID-19 Here's why the vast majority of people should NOT be wearing face masks to combat the coronavirus. Editor's Note 22/04/20:  An earlier version of this article stated that the coronavirus is not airborne. This has been changed to reflect the lack of a scientific consensus. Today, the World Health Organization still states that face masks should be worn wisely as their misuse can cause infections, and their overuse causes shortages for frontline workers. It's normal to be scared in the face of a new virus that we know relatively little...
