Study identifies “night owl” gene variant

If you’ve been a night owl all your life and mornings are your nemesis, you may be able to blame a gene mutation for all those late nights.

Researchers at The Rockefeller University have discovered that a variant of the gene CRY1 slows the internal biological clock—called the circadian clock—that normally dictates when you feel sleepy each night and when you’re ready to wake.
