Best of Last Week–First ‘image’ of dark matter web, why shoes come untied and a link between brain structure and anxiety

(ScienceX)—It was another good week for physics as an international team of researchers discovered strange forces acting on nanoparticles, which were related to looking at the Casimir Effect using quantum field theory. Also, a trio of physicists from LSU in the U.S. and Universidad de Valencia in Spain reported on their discovery of hidden aspects of electrodynamics, which they claimed advanced Maxwell’s theory of electromagnetism. And a team at the University of Waterloo captured the first ‘image’ of a dark matter web that connects galaxies—a composite image depicting what the team believes is dark matter exerting a force between multiple galaxies, tying them together.
