A Faster Way to Find the Origin of Malaria

The New York Times Writes:

By using a DNA “bar code” of 23 short snips from the genes of parasites that cause malaria, scientists can now often quickly determine where they originated, British researchers report.

The information could be useful in fighting local outbreaks, which may be caused by parasites from other parts of the world. And it should be possible to make a test kit that will get that information from a spot of dried blood in two hours — far less time than is needed to sequence a whole genome.  More...
