TWiEVO 47: On the origin of beer species

Nels and Vincent trace the origins of Saccharomyces cerevisiae strains used to make beer, and find that ales and lagers are made with yeasts that were derived from those used to make European grape wine and Asian rice wine.

TWiEVO 46: Can an old tumor teach us new tricks?

Nels and Vincent analyze the genomes of canine transmissible tumors to provide insight into the worldwide spread of the disease from its origin in a single dog 4000-8500 years ago, and its diversity, mutation, and evolution.
