The little sleep

摘要

Maybe it's a brutal deadline that has kept you up. Or your newborn, who didn't let you sleep all night. Or perhaps you're just at a club and don't want to cut the party short. Even those of us who love our shuteye must admit that there are times when we wish we didn't need so much of it. Now a small group of researchers is starting to zero in on ways to squeeze a full night's sleep into fewer hours, using technology rather than drugs. If they succeed, they could do more than help us cram more activities into our waking hours - they could, in theory, provide an alternative route to the fountain of youth.
