(CNN) – It was just after midnight on an autumn evening in 1996 when Yuk Ming Dennis Lo made a discovery he knew would change modern medicine. Lo had discovered a “treasure trove” of valuable DNA floating freely in the bloodstream. His breakthrough would one day make it possible for pregnant women to safely screen their unborn children for genetic conditions, to map out the entire genome of their fetus, and potentially screen all ages for cancer at its earliest stages. All using a simple blood test.
