There is some good stuff on Scienceblogs right now:
Evolgen has an article about how the oft quoted 1% genetic difference between chimps and humans may hide much larger differences due to copy number and expression differences.
Jonah Lehrer reports on how the function of dreams may be to replay and consolidate daytime memories.
Mixing Memory mentions a paper that compares money and money-seeking behavior to drugs. Interesting. I never thought that Kara was into that sort of thing.

I'm quickly learning that these webmagazines really don't like my book. This review, however, is actually rather thoughtful. Daniel Engber of Slate begins by pointing out that neuroscientists are constantly quoting Proust:
My career as a grad student in neuroscience was filled with these obligatory…
This past summer, Matt Hahn presented a talk at the Society for Molecular Biology Evolution meeting and Evolution 2006 entitled "The 17% Solution: Gene Family Divergence Between Human And Chimpanzee". The basic premise was that, even though humans and chimps are ~99% identical at the DNA sequence…
