The total information world

Happy Thanksgiving (if you are an American)! It’s been a busy few days in the world of personal genomics. By coincidence I have a coauthored comment in Genome Biology out, Rumors of the death of consumer genomics are greatly exaggerated (it was written and submitted a while back). Show More Summary

The FDA and 23andMe

First, download your 23andMe raw results now if you have them. If you don’t know what’s going on, the FDA has finally started to move aggressively against the firm. Unfortunately this is not surprising, as this was foreshadowed years ago. Show More Summary

Open Thread, 11/24/13

One of the stranger call-ins on my interview with Kathleen Dunn last month was when a woman who proudly asserted that she was a math major in college asserted that 23andMe had told her she wasn’t at risk for any disease, but now in her 60s she had developed many illnesses. I didn’t want to be […] The post Open Thread, 11/24/13 appeared first on Gene Expression.

Our ancestors are part us…or the other way around?

Keeping a close watch on media representations of the new Nature paper on the ancient Siberian genome. Here’s The New York Times, 24,000-Year-Old Body Is Kin to Both Europeans and American Indians. I don’t have a problem with the title,...Show More Summary

The long First Age of mankind

“What it begins to suggest is that we’re looking at a ‘Lord of the Rings’-type world – that there were many hominid populations,” says Mark Thomas, an evolutionary geneticist at University College London who was at the meeting but was not involved in the work. Show More Summary

Open Thread, 11/17/2013

Finished J. P. Mallory’s The Origins of the Irish. Good book, but it was as illuminating as to the origins of the Irish as Danel Dennett’s Consciousness Explained was in explaining consciousness. The post Open Thread, 11/17/2013 appeared first on Gene Expression.

The color of life as a coincidence

I do love me some sprouts! Greens, bitters, strong flavors of all sorts. I’ve always been like this. Some of this is surely environment. My family comes from a part of South Asia known for its love of bracing and bold sensation. ButShow More Summary

Is that white supremacist part black?

Many of you probably know about Dave Chappelle’s black white supremacist sketch (NSFW video!), though fewer are aware of Leo Felton, a white supremacist (ex, after he was outed) with a black father (a less tragic outcome than Dan Burros, the Jewish American Nazi). Show More Summary

Isn’t he special!

There’s a nice letter in Nature right now with an understated title, Mating advantage for rare males in wild guppy populations. But if you dig deeper you see some moderately grand claims being made. The key issue is that the authorsShow More Summary

Right science

About a month back a researcher at Yale published survey results which showed that Tea Party members exhibited more science knowledge than the general public, somewhat to his chagrin. I wasn’t particularly surprised, because the knowledge of science as it relates to political ideology is somewhat complex. Show More Summary

bioRxiv is here

For years many in the biological sciences community have been jealous of the exist of arXiv. This preprint server allows researchers to distribute their work widely to all comers. On occasion when when there have been debates about mimicking...Show More Summary

Vaccination, and social information networks

If you have not read Julia Ioffe’s story about getting whooping cough at the age of 31 (also see follow up), you might want to. Here’s some further context, Vaccine Refusals Fueled California’s Whooping Cough Epidemic. This topic has...Show More Summary

Change is the only constant. The post Open Thread, 11/10/2013 appeared first on Gene Expression.

Selection happens; but where, when, and why?

One of the secondary issues which cropped up with Nina Davuluri winning Miss America is that it seems implausible that someone with her complexion would be able to win any Indian beauty contest. A quick skim of Google images “Miss India” will make clear the reality that I’m alluding to. Show More Summary

The future always advances

The last week has seen a lot of chatter about the slapping down of the diagnostic patent by Sequenom, Judge Invalidates Patent for a Down Syndrome Test: A federal judge has invalidated the central patent underlying a noninvasive method of detecting Down syndrome in fetuses without the risk of inducing a miscarriage.

Open Thread, 11/3/2013

After reading Ancestral Journeys, I decided to get J. P. Mallory’s The Origins of the Irish. A bit on the academic side for some, but definitely a good dive into the literature. Mallory is well aware of the latest genetic research, so this is as up-to-date as it gets. It’s a good case study in […] The post Open Thread, 11/3/2013 appeared first on Gene Expression.

The human genetic casserole

I haven’t said much about this article in Science, Ancient DNA Links Native Americans With Europe, because it would be an understatement to say I’m digesting it. I would offer up a caution that using terms like “Europeans” and “East Asians” for populations which flourished ~25,000 years ago might be misleading. Show More Summary

Our forefathers were fierce & our foremothers were faithful

One of the peculiarities of human historical genetics is that people can simultaneously accept the existence of aggressive polygynous males such as Genghis Khan, and promiscuous females who give rise to the idea that 1 out of 10 children have an incorrect assigned paternity. Show More Summary
