The Problem with Writing about Race“One of the purposes of this site was to develop something called ‘Liberal Race Realism,’ which is a movement that I started. Admittedly, it hasn’t gone anywhere at all. Actually, it has been a complete failure. But that is ok. Really what it shows though is just how messed up people, especially Americans, are about race.” – from robert lindsay via hbdbibliography.

White skin privilege“There is a widespread belief, particularly among proponents of whiteness studies, that notions of beauty are determined by power relationships…. This belief is so entrenched that little concern is shown for counterfactual evidence, such as the medieval trade in fair-skinned women for clients in North Africa, the Middle East, and South Asia…. [T]his pattern is inconsistent with the belief that power relationships determine notions of beauty.” – from peter frost.

Exposure to stress even before conception causes genetic changes to offspring“A female’s exposure to distress even before she conceives causes changes in the expression of a gene linked to the stress mechanism in the body — in the ovum and later in the brains of the offspring from when they are born, according to a new study on rats.”

Common DNA Markers Can Account for More Than Half of the Genetic Influence on Cognitive Abilities“In the same sample of 3,154 pairs of 12-year-old twins, we directly compared twin-study heritability estimates for cognitive abilities (language, verbal, nonverbal, and general) with GCTA estimates captured by 1.7 million DNA markers. We found that DNA markers tagged by the array accounted for .66 of the estimated heritability, reaffirming that cognitive abilities are heritable. Larger sample sizes alone will be sufficient to identify many of the genetic variants that influence cognitive abilities.” – via race/history/evolution notes.

Genotypes over-represented among college students are linked to better cognitive abilities and socioemotional adjustment“The present study investigated … genotype frequencies of 284 SNPs covering major neurotransmitter genes in a sample of 478 Chinese college students, comparing these frequencies with those of a community sample (the 1000 Genomes dataset)…. Results showed that 24 loci showed Hardy–Weinberg disequilibrium among college students, but only two of these were in disequilibrium in the 1000 Genomes sample. These loci were found to be associated with mathematical abilities, executive functions, motivation, and adjustment-related behaviors such as alcohol use and emotion recognition.” – via … somebody … can’t remember who. sorry!

Why Bacteria Commit Suicide“[I]nfected individuals self-destructed before they could spread the virus to others.”

Evolution via Roadkill“Cliff swallows that build nests that dangle precariously from highway overpasses have a lower chance of becoming roadkill than in years past thanks to a shorter wingspan that lets them dodge oncoming traffic. That’s the conclusion of a new study based on 3 decades of data collected on one population of the birds. The results suggest that shorter wingspan has been selected for over this time period because of the evolutionary pressure put on the population by cars.”

‘Out of Africa’ Story Being Rewritten Again“Our early human ancestors may have left Africa more recently than thought, between 62,000 and 95,000 years ago, suggests a new analysis of genetic material from fossil skeletons.” – see also Mitochondrial DNA tree calibrated with ancient DNA @race/history/evolution notes and Revised timescale of human mtDNA evolution from dienekes.

bonus bonus: Palestinian Mother Speaks Out About Daughter’s Honor Killing“[H]onor killing defendants [are] usually given light sentences. Three years in prison was the stiffest in these cases. Life sentences or execution were never a consideration…. Offenders receive reduced sentences pursuant to Article 18 of Penal Code no. 74 of 1936, which is entitled ‘Necessity.’ The article provides for ‘leniency in punishment for crimes that offenders have committed in order to avert consequences, which could cause irreparable damage to their honor, money, or the honor of those such offenders are obliged to protect.'”

bonus bonus bonus: The Hate List“[T]he [$]PLC’s site explains that it counts counted ‘1,007 active hate groups in the United States in 2012,’ including ‘organizations and their chapters.’ But ‘The Year in Hate and Extremism’ did not make the ‘chapter’ distinction explicit. It is rarely drawn out in the organization’s frequent media appearances, nor was it mentioned in a letter from the SPLC to the Justice Department warning of the growing threat.” – see also What’s hate got to do with it? @bad data, bad!

Mitochondrial DNA in Ancient Human Populations of Europe (der Sarkissian 2011)“This work presents direct evidence that Mesolithic eastern Europeans belonged to the same Palaeolithic/Mesolithic genetic background as central and northern Europeans. It was also shown that prehistoric eastern Europeans were the recipients of multiple migrations from the East in prehistory that had not been previously detected and/or timed on the basis of modern mtDNA data. Ancient DNA also provided insights in the genetic history of European genetic outliers; the Saami, whose ancestral population still remain unidentified, and the Sardinians, whose genetic differentiation is proposed to be the result of mating isolation since at least the Bronze Age.” – @dienekes’.

Human Brain Networks Can be Tattle Tales“Greicius and his colleagues have previously shown that the brain operates, at least to some extent, as a composite of separate networks composed a number of distinct but simultaneously active brain regions. They have identified approximately 15 such networks. Different networks are associated with vision, hearing, language, memory, decision-making, emotion and so forth.” @al fin.

Looking for Empathy in a Conflict-Ridden World“The regions in red, he said, represented how subjects responded to others in physical pain; the green areas represented their response to emotional suffering. ‘The second thing you can see is that they’re completely separate from each other. So the brain regions that are responding to physical pain are very different than the brain regions that are responding to emotional suffering,’ he trailed off….”
