Researchers sequence the oldest DNA ever recovered, and the people bringing art and science together.

In this episode:

00:46 Million-year-old mammoth DNA

This week, researchers have smashed a long-standing record by sequencing a genome that's over a million years old. They achieved this feat by extracting DNA from permafrost-preserved mammoth teeth, using it to build-up a more detailed family tree for these ancient animals.

12:18 Putting art into science (and science into art)

Art and science are sometimes considered disparate, but when brought together the results can be greater than the sum of their parts. This week we hear from an artist and a scientist on the benefits they found when crossing the divide.
