If you happen to be a yeast population geneticist, then you probably already know about the Saccharomyces Genome Resequencing Project. They have resequenced 32 strains of S. cerevisiae and 27 strains of S. paradoxus at between 1x and 3x coverage. The nice thing about resequencing is that SNP discovery and genotyping occur simultaneously. That's in contrast to the human HapMap project which identified polymorphism in a few individuals, then searched for those polymorphisms in a larger panel. That means you can do some good population genetic analyses on the yeast data, which are not possible on the human data due to the ascertainment biases in the genotyping of HapMap individuals.

What a curious paper — it's fine research, and it's a useful dollop of data, but it's simultaneously so 21st century and on the edge of being completely trivial. It's like a tiny shard of the future whipping by on its way to quaintness.

If you've read any of the many stories lately about Craig Venter or Jim Watson's genome, you've probably seen a "SNP" appear somewhere. (If you haven't read any of the stories, CNN has one here, and my fellow bloggers have posted several here, here, here, here, here, and here.)

I recently was in a conversation with a collaborator who isn't in the genomics biz, and said collaborator remarked that there was a lot of online criticism of the quality of the genomic data that has been generated for the E. coli O104:H4 outbreak isolates. I've been following it very closely (not…
