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!

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!
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.”
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!
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!
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.”
