Published Ultrasound has potential to damage coronaviruses, study finds
(via sciencedaily.com) A new study suggests coronaviruses, including the virus that causes COVID-19, may be vulnerable to ultrasound vibrations. Simulations suggest ultrasound waves at medical imaging frequencies can cause the virus' shell and spikes to collapse and rupture.
Published Quadruple fusion imaging via transparent ultrasound transducer
(via sciencedaily.com) Scientists have developed a quadruple fusion optical and ultrasound imaging system using a transparent ultrasound transducer.
Published Standard vital signs could help estimate people's pain levels
(via sciencedaily.com) A new study demonstrates that machine-learning strategies can be applied to routinely collected physiological data, such as heart rate and blood pressure, to provide clues about pain levels in people with sickle cell disease.
Published Life's rich pattern: Researchers use sound to shape the future of printing
(via sciencedaily.com) Original source Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.
Published In era of online learning, new testing method aims to reduce cheating
(via sciencedaily.com) Engineers demonstrate how a testing strategy they call 'distanced online testing' can effectively reduce students' ability to receive help from one another in order to score higher on a test taken at individual homes during social distancing.
Published AI identifies social bias trends in Bollywood, Hollywood movies
(via sciencedaily.com) An automated computer analysis method designed by Carnegie Mellon University computer scientists makes it possible to track social biases across decades of Bollywood and Hollywood movies.
Published Swimming upstream on sound waves
(via sciencedaily.com) Original source Scientists have succeeded in propelling microvehicles against a fluid flow using ultrasound. In future, these tiny vehicles are set to be introduced into the human bloodstream, thereby revolutionizing the field of medicine.
Published To find the right network model, compare all possible histories
(via sciencedaily.com) Scientists rarely have the historical data they need to see exactly how nodes in a network became connected. But a new article offers hope for reconstructing the missing information, using a new method to evaluate the rules that generate network models.
Published Like adults, children by age 3 prefer seeing fractal patterns
(via sciencedaily.com) By the time children are 3 years old they already have an adult-like preference for visual fractal patterns commonly seen in nature, according to researchers.
Published New computational method validates images without 'ground truth'
(via sciencedaily.com) Researchers have developed a computational method that allows them to determine not if an entire imaging picture is accurate, but if any given point on the image is probable, based on the assumptions built into the model.
Published COVID-19 'super-spreading' events play outsized role in overall disease transmission
(via sciencedaily.com) Original source Researchers find COVID-19 super-spreading events, in which one person infects more than six other people, are much more frequent than anticipated, and that they have an outsized contribution to coronavirus transmission.
Published Researchers discover a uniquely quantum effect in erasing information
(via sciencedaily.com) Original source Researchers have discovered a uniquely quantum effect in erasing information that may have significant implications for the design of quantum computing chips. Their surprising discovery brings back to life the paradoxical 'Maxwell's demo', which has tormented physicists for over 150 years.
