Over the years, there have been many theories for why people yawn. It has been associated with sleepiness and boredom, and, incorrectly, with low oxygen levels in the blood.

"No one knows why we yawn," says Andrew C. Gallup, a psychology professor at the State University of New York at Albany.

Now Dr. Gallup and fellow researchers have a new explanation: yawning, they said, is a way for the body to cool the brain.

The volunteers were asked to step into a room by themselves and watch a video showing people behaving neutrally, laughing or yawning.

Some volunteers were asked to breathe only through their noses as they watched. Later, volunteers were asked to press warm or cold packs on their foreheads.

"The two conditions thought to promote brain cooling (nasal breathing and forehead cooling) practically eliminated contagious yawning," the researchers wrote.

The study may also help explain why yawning spreads from person to person. A cooler brain, Dr. Gallup said, is a clearer brain.

So yawning actually appears to be a way to stay more alert. And contagious yawning, he said, may have evolved to help groups remain vigilant against danger.

For centuries, two races of robotic aliens–the Autobots and the Decepticons–have waged a war, with the fate of the universe at stake. When the battle comes to Earth, all that stands between the evil Decepticons and ultimate power is a clue held by young Sam Witwicky (Shia LaBeouf).

An average teenager, Sam is consumed with everyday worries about school, friends, cars and girls. Unaware that he alone is mankind’s last chance for survival, Sam and his friend Mikaela (Megan Fox) find themselves in a tug of war between the Autobots and Decepticons. With the world hanging in the balance, Sam comes to realize the true meaning behind the Witwicky family motto–“No sacrifice, no victory!”
