Published New approach to centuries-old 'three-body problem'
(via sciencedaily.com) The "three-body problem," the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mechanical problems, and has occupied some of the world's best physicists, astronomers and mathematicians for over three centuries. Their attempts have led to the discovery of several important fields of science; yet its solution remained a mystery.
Published New statistical method eases data reproducibility crisis
(via sciencedaily.com) A reproducibility crisis is ongoing in scientific research, where many studies may be difficult or impossible to replicate and thereby validate, especially when the study involves a very large sample size. Now researchers have developed a statistical tool that can accurately estimate the replicability of a study, thus eliminating the need to duplicate the work and effectively mitigating the reproducibility crisis.
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 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 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.
