Analyzing the Bigfoot genome

Back in February, a Texas forensic scientist announced that she'd identified a DNA sample from Bigfoot and had sequenced the creature's genome. Now the sequences have been released for wider scrutiny and Ars Technica's John Timmer had a chance to dig into the data and speak with the discoverer of the possible Bigfoot genome. This is a story that, I think, everybody can enjoy — a skeptical analysis that's respectful to the Bigfoot researchers and genuinely interested in understanding where the DNA in question came from and what the genome sequences can tell us.

The oldest genome ever sequenced

Scientists at the University of Copenhagen sequenced the oldest genome yet — 700,000-year-old DNA from an ancient ancestor of the horse. The Nature Podcast explains why doing this is valuable (and, no, it's not about creating a cloned ancient horse park) and how you go about sequencing such elderly, and thus degraded, DNA.
