Ancient DNA: 25 years of agony and ecstasy

It has been 25 years since a team led by Allan Wilson extracted mitochondrial DNA from a museum specimen of the now-extinct quagga. On Science's Origins blog, I report from an ancient DNA meeting in Paris on the ups and downs of the field of paleogenetics, which has given us embarassments such as "dinosaur DNA" and triumps like the Neandertal genome.

Yet another health insurance outrage. A girl of 17 has her insurance cancelled after being diagnosed with celiac disease. Yet another reason to put the health insurance industry out of business. Thanks to PG for the heads up.
