a day late. sorry! sometimes sh*t just happens. (~_^)

Ethnic disparities in breast cancer survival remain despite socioeconomic similarities“All-cause survival was worse for African-Americans and better for Latinas and Asian-Americans compared with non-Latina whites after adjusting for age, study and tumor characteristics. When the researchers additionally adjusted for treatment and reproductive and lifestyle factors, they found that African-Americans had similar survival rates to non-Latina whites, but the survival rates of Latinas and Asian-Americans remained better.”

Diversity may be fatal, says new government health study“[P]eople suffer less cancer and heart disease when they live among their racial or ethnic peers.” – via mangan’s.

If Smart Is the Norm, Stupidity Gets More Interesting“Human intelligence varies.” – you don’t say?! (it’s in the nyt, believe it or not!)

Do Intelligent People Drink More Alcohol? – yes. yes, we do. (*hic*)

A detour through Europe?“The lithic technology of southwestern France (c. 22,000-17,000 BP) strangely resembles that of the first paleo-Amerindians (c. 12,000). Some people speculate that early Europeans reached North America by crossing the Atlantic. The truth is even more incredible. Early Europeans spread eastward and became the ancestors not only of the Amerindians but also of East Asians.” – from peter frost.

Smoking causes asthma in second generation offspring – epigenetic effects in rats.

Epigenetic inheritance is a wild goose chase“Epigenetics matters, but not between generations.”

Appearance-based politics: Sex-typed facial cues communicate political party affiliation – republican women more feminine looking than democrat women.

Who Would Win in a Fight: a Modern Human or a Neanderthal?“We beat them at evolution. But what about fisticuffs?”

The Island Where People Forget to Die“[P]eople on Ikaria were, in fact, reaching the age of 90 at two and a half times the rate Americans do. (Ikarian men in particular are nearly four times as likely as their American counterparts to reach 90, often in better health.) But more than that, they were also living about 8 to 10 years longer before succumbing to cancers and cardiovascular disease, and they suffered less depression and about a quarter the rate of dementia.”

  1. In combination with Putnam’s research the following links lend credence to the idea that diversity is unhealthy:

    http://www.uic.edu/classes/osci/osci590/14_2%20The%20Roseto%20Effect.htm

    about the importance of social networks in health and longevity, and

    http://www.ncbi.nlm.nih.gov/pubmed/21243077

    a paper on the social regulation of human gene expression.

    Mangan might also be interested in a book by David Corfield entitled ‘Why Do People Get Ill?: Exploring the Mind-body Connection’. I haven’t read it, but I know of the author from his work on the philosophy of mathematics, and he seems like a smart guy.
    I’d make this comment at Mangan’s but I am too lazy to create an id. I hope he reads your blog.

    But…but…it’s a magic explanation of the Black-White IQ gap!

  3. “the evidence for such a process is sketchy-while the evidence that it has negligible impact, even if it can occasionally happen, is strong.”

    Is he saying there’s actual evidence that transgenerational effects have a negligible impact? So… someone already devised a regression model to determine the precise degree of environmental correlation for every measurable human trait previously assumed to independently vary? That’s amazing.

  4. Given what’s going on in this country and in the world, it’s a wonder that everyone with an IQ of over 85 isn’t totally hammered by lunchtime…

    heh. nooooo, i don’t think that’s what he’s saying, mr. smarty pants. (~_^)

    but you make an excellent point. i’m not convinced, either, that epigenetic effects are negligible. dunno how important they are one way or t’other, yet.

    If genetic load causes stupidity shouldn’t outbreeding raise intelligence? Does that work for Ashkenazis? I don’t think so.

  8. @luke – “If genetic load causes stupidity shouldn’t outbreeding raise intelligence?”

    well, i think the answer is that there’s more than one way to skin a cat. i think you can get to an end phenotypic result (higher iq, for example) via different genetic routes (either inbreeding or outbreeding) — what matters is what’s selected for.

    inbreeding is not, necessarily, a bad thing — like linton said, “Inbreeding is line breeding that goes badly; line breeding is inbeeding that goes well.” and obviously (i think) in the case of ashkenazi jews, it helped them on their way to having a pretty high average iq — but without the right selection pressures (i.e. that successful medieval jewish businessmen left behind the most kids), that wouldn’t have been the end result.

    also, inbreeding is not the only way to increase genetic load — see the recent discussions over @west hunter re. paternal age.
