Copper, but not silver, is effective against SARS-CoV-2 on surfaces
As a result of corrosion, copper and silver release positively charged ions into their environment, which are harmful to bacteria in several ways and prevent their growth or kill them completely. This effect has long been exploited, for example by co.....»»
Headband-like device uses speckle contrast optical spectroscopy to predict stroke risk
A team of researchers from the Keck School of Medicine of USC and California Institute of Technology (Caltech) have developed a potential new way to measure a person's stroke risk that is cost-effective and noninvasive, akin to a cardiac stress test......»»
