This material relates to a paper that appeared in the Aug. 17, 2018, issue of Science, published by AAAS. The paper, by Jeffrey Aguilar at Georgia Institute of Technology in Atlanta, GA, and colleagues was titled, "Collective clog control: Optimizing traffic flow in confined biological and robophysical excavation." view more
