Our Microbiome May Be Looking Out for Itself

Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.
Maybe the microbiome is our puppet master.

Breast cancer rules rewritten in 'landmark' study

What we currently call breast cancer should be thought of as 10 completely separate diseases, according to an international study which has been described as a "landmark". The categories could improve treatment by tailoring drugs for a patient's exact type of breast cancer and help predict survival more accurately. The study in Nature analysed breast cancers from 2,000 women [Abstract] . It will take at least three years for the findings to be used in hospitals. [more inside]

Buzzing about network graphs

A hive plot (slides) is a beautiful and compelling way to visualize multiple, complex networks, without resorting to "hairball" graphs that are often difficult to qualitatively compare and contrast. [more inside]

Possible pre-Columbian Native American gene found in modern Icelanders

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.

"You Can't Patent Nature"

Followup to this post: A US District Court has ruled that Myriad Genetic's patents on breast cancer genes BRCA1 and BRCA2, which allow them to hold exclusive rights to a widely used genetic test for inherited breast and ovarian cancer susceptibility, are invalid. Genomics Law Report analyzes the ruling in two posts. The decision is likely to be challenged in a legal appeal — but if upheld, it could have huge implications for the biotechnology industry.

I'm sure this'll end well....

We may soon be able to clone Neanderthals. But should we? An essay from Archaeology Magazine examines the ethical, scientific and legal ramifications. (Via Heather Pringle's Time Machine blog, where essay author Zach Zorich posted a reply and elicited a response.) [more inside]

Do they preserve scientific transparency, protect profits or both?

On behalf of medical organizations, universities, & individual patients, pathologists and genetics researchers, the ACLU has filed a lawsuit against Utah-based Myriad Genetics and the US Patent and Trademark Office. Myriad holds the US patents to the BRCA1 and BRCA2 genes, associated with hereditary causes of breast and ovarian cancers. Their patents guarantee the company the right to prevent anyone else from testing or studying those genes, which the ACLU says is unconstitutional and inhibits researchers from finding treatments and cures.

so what's in that 0.1%?

DNA used to ascertain race of unidentified serial killer. Florida company DNAPrint Genomics claims their test can identify the race (ie, African, Caucasian, East Asian or American Indian) of a person from their DNA. CEO Tony Frudakis says that "of over 2,200 blind samples tested, the test is yet to get one wrong."
