Seems nobody told Jack Andraka that he was too young to invent a revolutionary fast, cheap and accurate early-detection test for pancreatic cancer. Oh that’s right. A whole bunch of scientists did. But that didn’t stop him from pursuing his invention, which uses a special kind of test strip paper, sort of like the kind diabetic use, to show the presence of a protein linked to cancer. He walked away with $75,000 for winning the grand prize at the 2012 Intel International Science and Engineering Fair and a really fun appearance on the Colbert Report. So no excuses. If you’ve got a great idea, don’t give up until the world sees it.
