Never seem to be able to get enough out of your days? Well, according to New Scientist's Short Sharp Science blog, researchers have figured out a way to keep you up for 25 hours at a time without using espresso! A new study shows that 45 minute blasts of bright light, administered late in the day, can affect a human's circadian rhythm such that people who normally sleep 8 hours, and are up for about 16, can suddenly stretch their days out for another 9 hours or so. The research has incredible implications, not just for students, workaholics and the TV show 24, but also for when humans make the move to another planet with longer days. Of course, if you've managed to pull off the 4-Hour Work Week, like Tim Ferriss's new book is suggesting, maybe you don't need the extra time. Read more here at New Scientist.
