We might've just met the most ambitious Canadian teen ever!
16-year-old Ann Makosinski won second place in a local science fair with the invention of a flashlight powered solely by hand heat—inspired by a friend from the Philippines who didn't have electricity, and was failing school because of it!
And after winning the prestigious 2013 Google science fair (which her teacher convinced her to apply), she's on her way to changing the world for the better and brighter.
But how does it work?!

While many associate yawning with a certain level of tiredness, new research indicates that yawning could serve as a method for regulating brain temperature.
After studying the yawning frequency of 160 people in the winter and summer in Tucson, Ariz., Princeton University researchers found that participants were more likely to yawn in the winter as opposed to the summer.
The results have lead researchers to believe that a purpose of yawning may be to cool down our brains!
According to the thermoregulatory theory of yawning, our brains stay cool through a heat exchange with the air drawn in during a yawn. Summer temperatures warmer than our body heat don't provide the relief necessary for our overheated brains.

Earlier this week Jockey launched their newest collection of underwear and it's cool — literally.
The new staycool undies are printed with Outlast® technology, a treatment that regulates skin temperature.
In fact it can cool you down, "down there", up to 3 degrees.
If the vagina cooling panties freak you out too much, Jockey also offers a t-shirt and tank top with the same Outlast technology. And they're reversible!
