How A Virus Hid In Our Genome For Six Million Years. Carl Zimmer writes for Phenomena [more inside]
In 2001, we learned the sequence of our genome; now, we have amassed a vast amount of knowledge about what those sequences actually do. Yesterday, the data from the ENCODE project went live. [more inside]
An Icelandic company called deCODE genetics (previously) has found evidence, though not conclusive, that an unknown American woman traveled to Iceland, possibly against her will, as early the year 1000 but not later than 1700. She had offspring in Iceland with natives. 80 of her descendants are still extant in that country. This finding has been announced in a pre-print online publication of the American Journal of Physical Anthropology. The work involved explorations of mitochondrial DNA, which are frequently employed to examine humans' centuries-old lineages. One surprising result is that this lineage does not seem to line up with previously known Native American genetic markers, but the authors believe that the explanation above is "[more] likely" than this common ancestor being European or Asian.

Scientists at the University of Copenhagen have become the first to reconstruct the nuclear genome of an extinct human being. The reconstruction serves as blueprint that scientists can use to give a description of how the pre-historic Greenlander, Inuk, looked - including his tendency to baldness, dry earwax, brown eyes, dark skin, the blood type A+, shovel-shaped front teeth, and that he was genetically adapted to cold temperatures, and to what extend he was predisposed to certain illnesses.
Want your genome on a hard drive but don't have the money? 23andMe can give you almost that: a scan of your SNPs, presented online and complete with analyses derived from up-to-date medical research (and a few educated guesses). Eight months ago, blogs were rife with speculation of who 23 could be and what the connection with Google could mean. [more inside]
As the Human Genome Project gets closer to unlocking the entire genetic code that makes up human beings, Clinton is urging researchers to keep it open to all. Apparently many pharmaceutical companies have patents on chunks of the code and uses for it. The government funded research continues to be posted to the web, hopefully the entire database will be available when they're done.
