Comparative Genomics in Humans and Chimps.
A recent article by some folks at Cornell and Celera is generating some hype in the science blogosphere (for a brief synopsis, click here). You can read about it at the Loom, Pharyngula, and Mike the Mad Biologist. All three blogs provide good summaries and discussions of the results, so I won't add very much.
What makes this study better than your run-of-the-mill comparative analysis is the inclusion of polymorphism data. For example, they could infer selective sweeps in SCML1 based on the lack of intraspecific polymorphisms. Also, the interpretation of the results adds to the general appeal. If you wanna know why, read the article, synopsis, or blog entries for yourself.
