(Phys.org)—Scientists have designed and built an acoustic one-way tunnel that allows sound to pass through in one direction only while blocking it from passing through in the opposite direction. The tunnel is completely ...
(Phys.org)—A team of researchers with Second University of Naples has developed a model that may help explain how it is that some earthquakes set off other earthquakes up to a thousand miles away. In their paper published ...
Commercial fluorescence activated cell sorters have been highly successful in the past 40 years at rapidly and accurately aiding medical diagnosis and biological studies, but they are bulky and too expensive ($200,000 -$1,000,000) ...
