Without wishing to rain on the kids parade... There are two aspects to the reported work. The first is the use of carbon nanotube biosensors incorporating antibodies. Google shows they've been around for a while and are reportedly more sensitive than previous methods. The second is using the levels of mesothelin to diagnose pancreatic cancer, this is less widely established, but was also recently reported by a different lab (http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0040157 http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjourna...). Putting the two together seems to be the work of Jack Andraka.
