DNA Evidence for Strong Genome-Wide Pleiotropy of Cognitive and Learning Abilities – “Genetic correlations were greater than 0.70 between general cognitive ability and language, reading, and mathematics, results that were highly similar to twin study estimates of genetic correlations. These results indicate that genes related to diverse neurocognitive processes have general rather than specific effects.” – via jayman!
Insulin differs between ethnicities, study finds – “People have differing abilities to release and react to insulin depending on ethnicity, according to a new study from researchers at Lund University in Sweden, Stanford University and Kitasato University.” – see also previous linkfest.
I Don’t Feel Your Pain – “A recent study shows that people, including medical personnel, assume black people feel less pain than white people…. In each experiment, the researchers found that white participants, black participants, and nurses and nursing students assumed that blacks felt less pain than whites.” – original research article.
Studying Tumors Differently, in Hopes of Outsmarting Them – “[C]ancer: It is an evolutionary disease.”
Accelerating adaptive evolution in humans – “In my last post, I noted R.A. Fisher’s argument that a larger population leads to more mutations and greater potential for adaptive evolution. As human populations have undergone massive growth over recent tens of thousands of years, we would expect the evidence of this population growth to show in our genomes. In this post, I point to a couple of papers that look at this evidence.” – from jason collins.

How Long Can You Wait to Have a Baby? – “[M]illions of women are being told when to get pregnant based on statistics from a time before electricity, antibiotics, or fertility treatment. Most people assume these numbers are based on large, well-conducted studies of modern women, but they are not.”
Grandparents effect spotted in British class system – “Children’s eventual position in Britain’s class system is closely linked to that of their grandparents, not just their parents, academics say. And where parents have ‘dropped down’ the socio-economic ladder, the so-called ‘grandparents effect’ often pulls them back up, research suggests…. [A]mong men with both parents and grandparents in the highest socio-economic group, 80% stayed in those positions when they were adults. But among men whose parents had been upwardly mobile, only 61% stayed in the group they had been born in to.” – don’t they mean the “regression to the mean effect’? – via jason collins.
Study: People With a Lot of Self-Control Are Happier – “Improbably enough, people who are better able to resist impulses report being more satisfied with their lives.”
Clues in the Cycle of Suicide – “Every year, suicide peaks with the tulips and lilacs — increasing roughly 15 percent over the annual average to create one of psychiatry’s most consistent epidemiological patterns. It may seem perverse that the period of spring and early summer … should contain ‘a capacity for self-murder that winter less often has.’ Yet it does.”

Does life have a purpose? – “Nobody expects atoms and molecules to have purposes, so why do we still think of living things in this way?”
Sardinian family’s tip for a long life: minestrone – and good longevity genes! (~_^) – “Luca Deiana, a professor of clinical biochemistry at the university of Sassari in Sardinia, who has studied some 2500 centenarians on the island since 1996, was quoted by Corriere della Sera at the time as saying the longevity of local inhabitants was influenced by genetics along with environmental, nutritional and lifestyle habits.”
Chilean Mummies Reveal Ancient Nicotine Habit – “The hair of mummies from the town of San Pedro de Atacama in Chile reveals the people in the region had a nicotine habit spanning from at least 100 B.C. to A.D. 1450.”
Mysterious Pair Buried With Flowers — Oldest Example Yet – “The pair — an adult male and an adolescent of undetermined sex — belonged to the primitive Natufian culture, which flourished between 15,000 and 11,600 years ago in an area that is now Israel, Jordan, Lebanon, and Syria.”
