Why science needs philosophy. The day the earth died. What are the limits of deep learning? In defence of the black box. Cats know their names. Using physics to make sense of the brain's tangled networks. Brain implants that let you speak your mind. Group formation and cohesion of active particles with visual perception–dependent motility. Stadium shows in the age of mechanical reproduction. The new physics needed to probe the origins of life. Brains speed up perception by guessing what’s next. And more.
