With scientific advances, sometimes you need to read between the lines. At first glance, all looks well with a successful new test developed by researchers at the Chinese University of Hong Kong.

The new test, announced online by the Proceedings of the National Academy of Sciences, requires no such invasive measures. It compares the baby's DNA in the mother's blood with her own DNA. The key breakthrough came when researchers employed digital technology to count individual mutant or normal DNA sequences.
