Researchers at Johns Hopkins University have developed a way to monitor the progress of a patient’s cancer treatment using a new technique for rapidly sequencing, or decoding, large amounts of DNA.

n the process, they have shaken up the textbook doctrine that everyone has a single version of the DNA in their mitochondria, the numerous energy-providing machines inside each cell. Besides the mutations, or changes, in DNA found in cancer patients, even healthy people turned out to have several variants in their mitochondrial DNA, though mostly in small proportions... read more
