Nanopore sequencing has arrived. Passing test after test this past year--including one we discuss today--this technology which was being hyped decades ago is delivering on its promise. Winston Timp joins us today. He's an assistant professor at Johns Hopkins and one of the leaders on a recent large scale project to directly sequence RNA on an array of nanopores. Winston's is the first in a series of shows we've lined up with users of Oxford Nanopore's technology. Why RNA-seq? Hasn’t this been done for years?
