We’ve all hit the snooze button when the alarm goes off, but why do we crave sleep in the first place? We explore the evolutionary origins of sleep … the study of narcolepsy in dogs … and could novel drugs and technologies cut down on our need for those zzzzs.
Plus, ditch your dream journal: a brain scanner may let you record – and play back – your dreams.
And, branch out with the latest development in artificial light: bioluminescent trees. How gene tinkering may make your houseplants both grow and glow.
