This kid found a 100% accurate (via blind testing on a human population) test to detect pancreatic, ovarian, and lung cancers. Pancreatic and Ovarian cancers are (per my gyno) difficult if not impossible to detect early, which makes them seriously deadly.
A 15 year old did it, and he did it in such a way that the test costs $0.03. THREE CENTS. He's so right: the interwebz is a powerful tool that can be just fantastic.
Or it can be used for duckface pictures.
