Brain tunes itself to criticality, maximizing information processing
New research from Washington University in St. Louis confirms that the brain tunes itself to a point where it is as excitable as it can be without tipping into disorder, similar to a phase transition. The new research from Keith Hengen, assistant professor of biology in Arts & Sciences, is published Oct. 7 in the…

The geometry of an electron determined for the first time
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest…
