Capturing a Hard-Wired Variability: What Makes Some Identical Twins Noticeably Different?“The current study finds that only one allele is expressed in between 12 and 24 percent of all such pairs encoded by the mouse genome. Further, the selection of expressed alleles varies randomly from cell to cell, and switches frequently between the two options throughout their lives…. ‘We find that for those genes that are not imprinted, roughly one in five alleles is randomly and dynamically expressed only one at a time,’ says Sandberg. ‘And if one allele is being expressed, the other doesn’t know about it. There’s no coordination between two.’”

A Living Time Capsule Shows the Human Mark on Evolution“Scientists have revived shrimp-like animals that have been buried at the bottom of the lake for an estimated 700 years. If this estimate holds up to further testing, they are the oldest animals ever resurrected…. The oldest DNA the scientists obtained from the lake dates back to around the time the Vandals were ransacking Rome. The scientists found that one genetic strain of water fleas dominated at the time — and continued to until the late 1800s. As phosphorus [from fertilizers] flooded the lake, a previously rare strain emerged and took over.”

Evolution Hidden in Plain Sight“One of the hallmarks of *Escherichia coli* as a species is that when there’s oxygen around, it can’t feed on a compound called citrate. But one day a flask turned cloudy with an explosion of *E. coli* that were doing just that. The change was so profound that it may mean these bacteria had evolved into a new species.”

SLC24A5 light skin pigmentation allele origin“‘The distributions of C11 and its parental haplotypes make it most likely that these two last steps occurred between the Middle East and the Indian subcontinent, with the A111T mutation occurring after the split between the ancestors of Europeans and East Asians.’” – @dienekes’.

The brown man with blue eyes“Interestingly, although the Luxembourg man was blue-eyed, he also had brown skin. He lacked the ‘European’ alleles at all three genes involved in the whitening of European skin.” – from peter frost.

Factor Analysis of Population Allele Frequencies as a Simple, Novel Method of Detecting Signals of Recent Polygenic Selection: The Example of Educational Attainment and IQ [pdf] – “Frequencies of 10 SNPs found to be associated with educational attainment in a recent genome-wide association study were obtained from HapMap, 1000 Genomes and ALFRED. Factor analysis showed that they are strongly statistically associated at the population level, and the resulting factor score was highly related to average population IQ (r=0.90). Moreover, allele frequencies were positively correlated with aggregate measures of educational attainment in the population, average IQ, and with two intelligence increasing alleles that had been identified in different studies.” – h/t elijah! see also jayman.

Ancient hunter-gatherers had rotten teeth“Scientists have long thought that tooth decay only became common in humans about 10,000 years ago, when we began farming – and eating starchy crops that fed sugar-loving bacteria on our teeth. But Isabelle De Groote of the Natural History Museum in London, UK, and her colleagues have found widespread tooth decay in hunter-gatherers that lived several thousand years before the origin of agriculture.”

The Liberal Illusion of Uniqueness“[L]iberals underestimate their similarity to other liberals (i.e., display *truly false uniqueness*), whereas moderates and conservatives overestimate their similarity to other moderates and conservatives (i.e., display *truly false consensus*…).” – h/t ben southwood!

Is the dark side of parenting genetic?“In a novel finding, Robert Plomin and colleagues suggest that negative aspects of parenting are more heritable than positive aspects. They call this The Dark Side of parenting. The effect is interesting and subtle: it suggests that whilst parents are generally consistent in their handling of their children, some genetically driven characteristics of their children lead them into more negative parenting styles…. In simple terms, even peaceable parents get irritable with difficult children.” – from dr. james thompson.

Changelings, Infanticide and Northwest European Guilt Culture“To summarize, the changeling lore provides evidence of a NWE guilt culture dating back at least to medieval times, and the practice and attitude towards exposure suggests that ancient Greece had an emerging guilt culture as early as the 400s BC which enabled a similar individualism and intellectual development that we’ve seen in the NWE in recent centuries.” – from staffan.

first of all — how come no one ever told me that the indian (as in call centers) diamond industry was run in large part by ca. 2500 jainist families? a lot of them from palanpur (see also here). from time magazine:

“The Surat diamond trade was built by a dynamic and enterprising religious community – the Palanpuri Jains, followers of an ancient religion that emphasizes nonviolence and vegetarianism. Jains account for 0.4% of India’s population. The Palanpuris, who hail from the town of Palanpur in the Indian state of Gujarat, form a close-knit community that thrives in the atmosphere of secrecy and informality that envelops the diamond trade – there are often no written contracts, many transactions occur in cash, and stones worth millions of dollars are transported with virtually no security. ‘It’s an industry built on trust,’ says Biju Patnaik, a Bombay-based diamond-industry expert at Dutch bank ABN AMRO. The Palanpuris have also ventured over-seas, setting up small family-run polishing centers in Antwerp and Tel Aviv, and slowly elbowing into the U.S. as diamond sellers. In Manhattan’s midtown diamond district, Palanpuri businessmen sitting beneath portraits of their saint, Mahavira, now run shops side by side with black-coated Hasidim from Brooklyn.”

yeah, it’s an industry built on trust all right … in family members! fellow inbred members prolly (there are some hints that cousin marriage is a-okay amongst the jains — and we know that uncle-niece marriage is allowed with that other diamond-trading group — the hasidim).

i suppose that, like me, you’re all closely following the story of the unfortunate mr. urooj khan who lived in chicago and who, the day after collecting his $1 million lotto winnings ($425,000 after taxes), DIED from CYANIDE poisoning!

the question is, whodunit?:

- his wife/cousin who cooked his last meal (kofta curry) which she may or may not have eaten with him (reports differ)?
- his father-in-law/uncle who lived with mr. khan and who owes $124,000 in back taxes?
- his brother-in-law/possible cousin (married to mr. khan’s sister) with whom mr. khan’s daughter by his first wife is now living and who is suing khan’s wife/estate for the daughter’s share of the lottery winnings (or so he says)?
- his brother who called the police to say that mr. khan’s death was suspicious and that they should exhume his body to check for any funny business (which they are gonna do)?
- someone else entirely?

if this were back in the old country, clearly there would be a clan war a-brewin’!

meanwhile, in israel:

1 dead, 6 apartments burned in J’lem clash of clans

these are arab, not jewish, clans…

“22-year-old man dies in hospital after being stabbed in a conflict between two family clans; six apartments, cars burned in fire.

A clash between two family clans (hamulot) in the northeast Jerusalem neighborhood of Beit Hanina left one man dead and led to a massive fire that burned six apartments on Tuesday….

“The warring Arab families threw rocks at police officers who tried to respond at the scene, though they did not injure anyone else, according to Jerusalem police spokesman Shmuel Ben-Ruby….”

very helpful. =/

When the going gets tough, the tough get… more relief from a placebo?“[T]he new findings link specific, established personality traits with an individual’s susceptibility to the placebo effect…. The researchers showed a significant link between certain personality traits and how much relief people said they felt when given the placebo – as well as the level of a specific chemical that their brains released…. The findings show that about one-quarter of placebo response was explained by the personality traits of resiliency, straightforwardness, altruism or anger/hostility, as measured on standardized tests.”

In Defense of Favoritism“Affective neuroscience research on early-childhood bonding suggests that, as mammals, we probably start out as emotionally glued microcommunities (family and tribe) before we become autonomous ego-driven creatures. Favoritism, not egoism, is probably the primal value system. In short, favoritism or bias toward your group is not intrinsically racist, sexist, or closed-minded. Privileging your tribe does not render you negative or bigoted toward those outside your tribe.”
