Genetic Variants Linked to Educational Attainment“A multi-national team of researchers has identified genetic markers that predict educational attainment by pooling data from more than 125,000 individuals in the United States, Australia, and 13 western European countries…. Combining the two million examined SNPs, the SSGAC researchers were able to explain about 2 percent of the variation in educational attainment across individuals, and anticipate that this figure will rise as larger samples become available.” – h/t friendly e-mailer! (^_^) – see also steve hsu on this: First GWAS hits for cognitive ability (thanks, grey!). in particular, check out steve’s graph. and john derbyshire for more on looking for iq-related genes via gwas studies. see also dr. james thompson: Educational attainment, intelligence, and the relentless cracking of the genetic code.

Deforestation Plants the Seed for Rapid Evolution in Brazil“The deforestation of the Brazilian rain forest has created a hidden consequence: The seeds of palm trees have evolved rapidly to be smaller.”

Gene switches make prairie voles fall in love“Researchers have shown for the first time that the act of mating induces permanent chemical modifications in the chromosomes, affecting the expression of genes that regulate sexual and monogamous behaviour.” – epigenetic effects!

Definitions of “Race” and Language and Race — a couple of great posts @habitable worlds!

Genetic structure and different population strata in Italy“‘Our results show that the Y-chromosomal genetic diversity of Italy is not clinal but structured in three geographical areas: North-Western Italy (NWI), South-Eastern Italy (SEI) and Sardinia (SAR). …suggesting a shared genetic background between Southern Italy and the Adriatic coast from one side, and between Northern Italy and Tuscany from the other side.’” – from dienekes!

Just For Show?“Of all humans, male and female, European women have the whitest skin and the most diverse range of hair and eye colors. Are European physical characteristics really female characteristics?” – from peter frost!

Apes Regret Bad Decisions, Throw Tantrums“When apes make a bad decision or took a gamble that doesn’t pay off, they bang on tables and perform other kinds of tantrum-like behaviors, often exhibiting regret by attempting to undo what they had done.”

How Birds and Babies Learn to Talk

GSS on Haidt’s Moral Foundations theory“The GSS results largely support Haidt’s divisions, with liberals putting greater emphasis on liberty/oppression and especially care/harm, just as he found to be the case. Conservatives, on the other hand, are more concerned with fairness/cheating, authority/subversion, sanctity/degradation, and loyalty/subversion than liberals are.” – from the awesome epigone!

Homosexuality is natural. Fine. But what if homophobia is natural, too?

The Ugly Truth About Obesity“So yes, the obese group is not unlike its negative stereotypes. Of the, ‘lazy’, ‘sloppy’, ‘less competent’, ‘lacking in self-discipline’, ‘disagreeable’, ‘less conscientious’, ‘poor role models’, ‘unintelligent’, ‘unsuccessful’, ‘weak-willed’, ‘unpleasant’, ‘overindulgent’, it seems ‘disagreeable’ and ‘unpleasant’ are the only clear misses. This is not to hate on the obese, but to call a spade a spade.” – from staffan!

The big fat truth“More and more studies show that being overweight does not always shorten life — but some public-health researchers would rather not talk about them.”

“Were the Victorians cleverer than us?” – from steve sailer!

What Science Says About Arousal During Rape

Breeding the Nutrition Out of Our Food“Studies published within the past 15 years show that much of our produce is relatively low in phytonutrients, which are the compounds with the potential to reduce the risk of four of our modern scourges: cancer, cardiovascular disease, diabetes and dementia. The loss of these beneficial nutrients did not begin 50 or 100 years ago, as many assume. Unwittingly, we have been stripping phytonutrients from our diet since we stopped foraging for wild plants some 10,000 years ago and became farmers.”

One gene helped human brains become complex“A single ancestral human gene that made two copies of itself may have helped the evolution of our large brains 2.5 million years ago, as our ancestors were diverging from australopithecines.”

The Great White Horse“A racial group is a partly inbred extended family. The inbreeding gives races more coherence and persistence than typical extended families.” – from steve sailer.

Why the British are free-thinking and the Chinese love conformity: It’s all in the genes claim scientists“The study, by the department of psychology at Northwestern University in Illinois, suggests that the individualism seen in western nations, and the higher levels of collectivism and family loyalty found in Asian cultures, are caused by differences in the prevalence of particular genes. ‘We demonstrate for the first time a robust association between cultural values of individualism–collectivism and the serotonin transporter gene,’ said Joan Chiao, from the department of psychology at Northwestern University.” — i know. it’s the daily mail. but it looks like the research will be coming out in the proceedings of the royal society: “Culture-gene coevolution of individualism-collectivism and the serotonin transporter gene (5-HTTLPR)” [in press]. see comments.

Insects have personality too, research on honey bees indicates“A new study in Science suggests that thrill-seeking is not limited to humans and other vertebrates. Some honey bees, too, are more likely than others to seek adventure. The brains of these novelty-seeking bees exhibit distinct patterns of gene activity in molecular pathways known to be associated with thrill-seeking in humans….”

New study shows that in US ‘hot spots,’ HIV infection among African-American women is 5-times higher than national estimate“Women constitute roughly one-quarter of new HIV infections in the U.S. with 66% of these infections occurring among black women, despite the fact that black women constitute only 14% of the U.S. female population.”
