And Finally…  Biomarker tests are not new, neither are dipstick tests, but what makes this one a breakthrough is its accuracy and speed--and the fact that it's been created by someone who's not even old enough to drive in his home state of Maryland. Fifteen-year-old Jack Andraka won the $75,000 top prize in the Intel International Science and Engineering Fair for his test to detect mesothelin, a protein biomarker elevated in prostate cancer.
