Flies see the world in slow motion, say scientists – “Flies avoid being swatted in the same way Keanu Reeves dodges flying bullets in The Matrix, by watching time pass slowly, research suggests. The smaller an animal is, and the faster its metabolic rate, the slower time passes for it, scientists found. This means that across a wide range of species, time perception is directly related to size, with animals smaller than us seeing the world in slow motion…. ‘It’s tempting to think that for children time moves more slowly than it does for grown ups, and there is some evidence that it might…. People have shown in humans that flicker fusion frequency is related to a person’s subjective perception of time, and it changes with age. It’s certainly faster in children.’“ – mind. blown.
Poverty Can Trump a Winning Hand of Genes – “When psychologists first started studying twins, they found identical twins much more likely to have similar IQs than fraternal ones. They concluded that IQ was highly “heritable”—that is, due to genetic differences. But those were all high SES twins. Erik Turkheimer of the University of Virginia and his colleagues discovered that the picture was very different for poor, low-SES twins. For these children, there was very little difference between identical and fraternal twins: IQ was hardly heritable at all…. Richer children have similarly good educational opportunities, so genetic differences among them become more apparent…. But for poor children, haphazard differences in educational opportunity swamp genetic differences.”
Shy male birds keep closer ‘friends’ – “Shy male great tits have fewer ‘friends’ but build stronger bonds than bolder birds, researchers have found.” – speaking of birds: Warblers begin migrating after interbreeding.
Pornography addiction leads to same brain activity as alcoholism or drug abuse, study shows – “Cambridge University scientists reveal changes in brain for compulsive porn users which don’t occur in those with no such habit.”
Redneck Psychiatrists – “Schizophrenia is more common in men than women – about 1.4 to 1. It’s more common in the lowest SES groups, although that may be downward drift. Schizophrenia is considerably more common among people of African ancestry…. Schizophrenia seems to be more common among people that grew up in cities – about twice as common.” – from greg cochran.
Painful and extreme rituals enhance social cohesion and charity – “The study of 86 males in Mauritius found both observers and performers of the Kavadi were more charitable than those who only participated in the collective prayers. The researchers also found that higher levels of pain were positively associated with larger donations and a more inclusive self-identity.”
Why parents think your partner isn’t good enough – “[P]arents tend to give more resources to children whose partners provide less support, and that this leads to a conflict over mate choice…. ‘Parents are equally related to all of their children, whereas children value themselves more than their siblings — so each child wants to get more than their fair share of parental resources.’ This means that the children are willing to settle for a mate who is less caring than their parents would ideally like.”
The Social Life of Genes – “Your DNA is not a blueprint. Day by day, week by week, your genes are in a conversation with your surroundings. Your neighbors, your family, your feelings of loneliness: They don’t just get under your skin, they get into the control rooms of your cells. Inside the new social science of genetics.” – h/t you know who you are!
Lifestyle Influences Metabolism via DNA Methylation – “An unhealthy lifestyle leaves traces in the DNA. These may have specific effects on metabolism, causing organ damage or disease. Scientists of Helmholtz Zentrum München have now identified 28 DNA alterations associated with metabolic traits. This world-first epigenome-wide association study (EWAS) of modified genes and metabolites has been now published in the journal Human Molecular Genetics.”

You’ll never be Chinese – “Except where there is economic benefit to be had, communities do not act together, and when they do it is only to ensure equal financial compensation for the pollution, or the government-sponsored illegal land grab, or the poisoned children.”
