　　NOVA: Mysteries of Sleep Like virtually every other animal, humans need sleep to survive. But why? What do we gain from spending nearly a third of our lives in such a defenseless state? And what's at stake if we sleep poorly? The functions of sleep have long been something of a mystery. But now scientists are peering deep into the brain to see what happens while we snooze. One study reveals that well-timed bursts of pink noise can nudge a person's brain waves, extending periods of slow-wave, or deep, sleep. And toddlers learning new words show that taking even a short nap after learning something new can help the information stick. And when it comes to sleeping poorly, it may turn out that having interrupted sleep can be just as harmful as missing sleep altogether. As scientists come to understand the powerful role that sleep -- or lack of it -- plays in everything from memory to trauma to emotion regulation, one thing is clear: This biological function is as crucial as it is complex.

　　"ADDICTED TO SEXTING"| a compelling (and sometimes humorous) look at the rise and proliferation of this social phenomenon from several varying perspectives and how
　　the lives of those engaged in it are affected. Throughout the course of the film| we examine nearly every aspect of what has become a national and international
　　pastime. A vast range of opinions give their input about this delicate subject and| as such| discussions with notable figures in the entertainment| political and
　　medical fields (among others) are included. The film touches on the many high profile scandals surrounding public officials and the resulting consequences of their
　　actions. In stark contrast| an honest look at the possibility of sexting as a positive development within the framework of healthy relationships is also presented.
　　Sexting exists and is not likely to disappear anytime soon. "ADDICTED TO SEXTING" shows the why| how and what possible purpose it serves.
