Big Picture Science – ZZZZZs Please

by Gary Niederhoff on May 27, 2013

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.

Listen to individual segments here:
Part 1: Emmanuel Mignot on why we sleep
Part 2: Kyle Taylor on bioluminescent flora
Part 3: Jerry Siegel on DARPA’s development of super stimulants
Part 4: Jack Gallant on re-creating visual images from dreams
