The photonic big bang: weak disorder creates a weak nanometric separation between photons with opposite spin (red and blue) - "photonic spin-Hall effect". Only in complete disorder does the "photonic explosion" occur - photons with opposite spins split and fill the entire momentum space - the "photonic Rashba effect". The phenomenon describes a topological phase transition that manifests itself in symmetry breaking. The research was inspired by models in cosmology that describe the Big Bang. Silicon nanoantennas are depicted in the picture, and the transition from antennas ordered in their direction to complete disorder is expressed by measuring a sharp increase in entropy (as a measure of disorder).

Gender differences in the human brain have led to the notion that brains are male or female. Research by Dafna Yoel from Tel Aviv University and her colleagues tells a different story. Illustration: pixabay.

Is there a "female mind"?
