Can a New Law of Physics Explain a Black Hole Paradox?

A group of physicists recently used circuit complexity, a concept from computer science, to describe the quantum evolution of physical systems. Some computer scientists who initially balked at the idea have since become its closest allies.

Could One Physics Theory Unlock the Mysteries of the Brain?

Some neuroscientists hypothesize that our brains work optimally at a "critical point" between subcritical and supercritical extremes. If so, brain diseases like epilepsy could be associated with a divergence from the critical point.
