Singel12 wants you to get enough sleep.

I often hear people bragging about their sleeping habits, saying things like, "I stayed up until midnight," or, "I only got four hours of sleep!" Why is it so fashionable to stay up late? I would rather get the rest I need! I decided to dive into the Internet and learn more about sleep.

Did you know you can stay alive longer without food than without sleep? Your body needs rest more than it needs food! You body needs to take a break from being constantly on the go. While we are sleeping, our brain is recharged and dead cells and tissue are repaired. While you are asleep, growth hormones are released, and these control your physical and mental development.

DrRabiah reports on an inspirational inventor.

Our friend William Kamkwamba was back in Chicago last week, as he and co-author Ryan Mealer set out on a tour to promote their new book "The Boy Who Harnessed the Wind". As we've written here on the Blog before, William - I use his first name because we're friends now :-) - is currently featured in the Museum of Science and Industry's Fast Forward . . . Inventing the Future exhibit.

William's innovation and determination as a teenager drove him to build a windmill out of scrap metal for his town, providing electricity and initiating a whirlwind journey that has taken William around the world. Lucky for us, that journey included a stop in Chicago in August to participate in LabFest!

So it was great to see him again last week during a special presentation and reception held at the Museum in honor of his book release.
