Evolution Going Great, Reports Trilobite:
"Things are looking mighty fine," announced the prehistoric invertebrate, taking measure of his surroundings through a series of small, hexagonal eyelets located at the tip of his thorax. "Sulfurous gas seems to be bubbling up to the surface pretty good, and several single-cell organisms appear to be mutating at a rather steady pace. Also, just today, I developed the ability to roll into a small protective shell in order to avoid predators".
Mapping human genetic diversity in Asia
Out in today's Science is Mapping Human Genetic Diversity in Asia
Asia harbors substantial cultural and linguistic diversity, but the geographic structure of genetic variation across the continent remains enigmatic. Here we report a large-scale survey of autosomal variation from a broad geographic sample of Asian human populations. Our results show that genetic ancestry is strongly correlated with linguistic affiliations as well as geography. Most populations show relatedness within ethnic/linguistic groups, despite prevalent gene flow among populations. More than 90% of East Asian (EA) haplotypes could be found in either Southeast Asian (SEA) or Central-South Asian (CSA) populations and show clinal structure with haplotype diversity decreasing from south to north. Furthermore, 50% of EA haplotypes were found in SEA only and 5% were found in CSA only, indicating that SEA was a major geographic source of EA populations.

Crux – A python library for molecular phylogenetics
Crux is a software toolkit for molecular phylogenetic inference that runs on (at least) Linux, FreeBSD, and Mac OS X. It is structured as a set of Python modules, which makes it possible to quickly develop Python scripts that perform unique, non-canned analyses.
H.M.’s brain to be dissected live online
If you've ever heard anything about cognitive psychology, then you've probably heard about H.M.
Henry Gustav Molaison (February 26, 1926 – December 2, 2008), better known as HM or H.M., was a memory-impaired patient who was widely studied from the late 1950s until his death. His case played a very important role in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology, a branch of psychology that aims to understand how the structure and function of the brain relates to specific psychological processes. (wikipedia)
Tomorrow - his brain will be dissected live online.
