‘Magic angle’ twisted trilayer graphene doesn’t only have an impressively exotic name, it might be a particularly rare type of superconductor, according to new research – one that could be useful everywhere from medical equipment to quantum computers.

Artificial intelligence (AI) is proving very adept at certain tasks – like inventing human faces that don’t actually exist, or winning games of poker – but these networks still struggle when it comes to something humans do naturally: imagine.

A new set of equations can precisely describe the reflections of the Universe that appear in the warped light around a black hole.
