Ethics: Taboo genetics and Dangerous work – not very subtle careful or you won’t ever be able to find work in this town again “advice” from the invertebrates @nature (no offense to invertebrates elsewhere). see also: steve hsu, steve sailer, and dr. james thompson. previously: alternate nature poll.

Genomics England“This project will sequence the personal DNA code – known as a genome – of up to 100,000 patients over the next five years.”

Your Genome Is a Post-Apocalyptic Wasteland“Your 25,000 genes reside in a genetic landscape littered with the rubble of ancient and ongoing battles with hordes of viruses, clone armies of genetic parasites, and zombie genes that should be dead but aren’t. Our messy genomic landscape is a dynamic, miniature ecosystem, and scientists are learning how its inhabitants play a big role in human health and disease.”

Morality and the Perspicuity of the True Believers“Consider, for example, a piece Dennis Prager just wrote for National Review Online, packaged as ‘A Response to Richard Dawkins.’ Prager cuts to the chase with the following: ‘If there is no God, the labels “good” and “evil” are merely opinions. They are substitutes for “I like it” and “I don’t like it.” They are not objective realities.’ Thank you, Mr. Prager. I couldn’t have said it better myself.” (^_^) – from helian.

Debate on Evolution of Multicellular Organisms Starts to Gain Focus“Cassandra Extavour and her colleagues, who study the origins of multicellular organisms and the evolution of cooperation, still disagree on the meaning of key concepts such as cooperation, competition and fitness.”

Let the good times roll?“The Frogs have had it rougher than the Canucks.” – from greg cochran. see also: French Canadians: The unexplained genetic diversity from peter frost.

Migration from Sweden to Poland during the Early Bronze Age“‘”Over 3800 years ago, a young male, possibly born in Skåne, made a journey of over 900 kilometers south, to Wroclaw in Poland. He died violently in Wroclaw, killed by Úněticean farmers, possibly due to romance with two local females, who were murdered together with him.”‘” @dienekes’.

Please Pass the Microbes“Once the animal had been processed more or less, I was amazed to see all three [hadza] men take a handful of the partially digested plant material from the recently removed stomach to scrub off the copious amounts of blood that now covered there hands and foreman’s. This was followed by a final ‘cleaning’ with dry grass for good measure. While I was fascinated by the microbe-laden stomach contents being used as hand scrubber – presumably transferring an extraordinary diversity of microbes from the Impala gut to the hands of the Hadza – I was not prepared for what they did next….” – you’ve GOT to read this! (^_^) – h/t john durant!

First physical evidence of why you’re an owl or a lark“They found a reduction in the integrity of night owls’ white matter – brain tissue largely comprised of fatty insulating material that speeds up the transmission of nerve signals – in areas associated with depression. ‘We think this could be caused by the fact that late chronotypes suffer from this permanent jet lag,’ says Rosenberg, although she cautions that further studies are needed to confirm cause and effect.”

Human brain boiled in its skull lasted 4000 years“Seyitömer Höyük – the Bronze Age settlement in western Turkey where this brain was found – is not in the mountains. So how did brain tissue survive in four skeletons dug up there between 2006 and 2011?”

Alien DNA could be ‘recreated’ on earth“Humans will be able to recreate alien life forms and ‘print out’ organisms using the biological equivalent of a 3D printer in the future, a DNA pioneer has predicted.” – craig venter.

Loci number and group difference“This paper shows that the debate about ‘variation within races is bigger than variation between races’ depends largely on the number of loci being analysed, and the assumptions being made about the significance of the revealed differences.” – from dr. james thompson.

Social Constructs are Social Constructs – heh. (^_^) – @handle’s haus. h/t konkvistador!

Human Hair Confirmed in Prehistoric Hyena Feces“The fossilized dung, part of a ‘hyena latrine,’ will be described in the upcoming October issue of the Journal of Archaeological Science…. Our ancestors there lived around a literally wild bunch about 257,000 years ago.” – #PaleoDiet! (O_O)

Academic fraud in China is getting out of hand“In a few short years, China has metamorphosed from a middling contributor to scientific knowledge into one of the most prolific research entities on the planet. But the country’s meteoric ascent to scientific prominence – widely attributed to a flawed incentive system – has given unintentional rise to a lucrative industry of academic fakery.” – see also: Looks good on paper @the economist.

Poll Shows Major Shift in Identity of U.S. Jews“The first major survey of American Jews in more than 10 years finds a significant rise in those who are not religious, marry outside the faith and are not raising their children Jewish — resulting in rapid assimilation that is sweeping through every branch of Judaism except the Orthodox.”

Electric Shock Therapy May Cut Crime By Stimulating Brain Region For Social Norm Compliance“An original way to reduce crimes rates could lie in regulating neural activity in a person’s front of the brain — right lateral prefrontal cortex. Scientists from the University of Zurich have found a brain mechanism responsible for social norm compliance is separate from the processes that represents a person’s knowledge and beliefs about societal norms. The neurons in this specific brain region may be controlled by electric shock therapy which could potentially stop criminals from breaking the law….” – see also: Brain Stimulation Can Control Compliance with Social Norms“Human beings are utterly dependent on a complex social structure for their survival. Since all behavior is controlled by the brain, human beings may have evolved specialized neural circuits that are responsible for compliance with society’s rules.” h/t михаи́л анисимов!

When the going gets tough, the tough get… more relief from a placebo?“[T]he new findings link specific, established personality traits with an individual’s susceptibility to the placebo effect…. The researchers showed a significant link between certain personality traits and how much relief people said they felt when given the placebo – as well as the level of a specific chemical that their brains released…. The findings show that about one-quarter of placebo response was explained by the personality traits of resiliency, straightforwardness, altruism or anger/hostility, as measured on standardized tests.”

Oxytocin Keeps Flirting Folks at Arm’s Length“[M]en who were in a committed relationship even maintained a greater distance from an attractive woman when under the influence of oxytocin than their control group.”

The mysterious Ainu“[I]s the physical similarity [of the Ainu] to Europeans just a matter of chance? Convergent evolution? No, it may be that the Ainu have just not changed as much physically as other East Asians. – from peter frost.

Pre-Neolithic Mediterranean Island settlement“‘[T]he first inhabitants of many of the Mediterranean islands may not have been modern humans at all. Instead, he says evidence has been found that shows that they might have been Neanderthals, or Homo Erectus.'” – from dienekes.

Why “Multicultural Society” is a Logical Impossibility

In Defense of Favoritism“Affective neuroscience research on early-childhood bonding suggests that, as mammals, we probably start out as emotionally glued microcommunities (family and tribe) before we become autonomous ego-driven creatures. Favoritism, not egoism, is probably the primal value system. In short, favoritism or bias toward your group is not intrinsically racist, sexist, or closed-minded. Privileging your tribe does not render you negative or bigoted toward those outside your tribe.”

Parents also choose“[I]n many if not most societies, men, i.e. fathers, decide which man is allowed to mate with his daughter or other female relative.” – @the breviary.

A GPS in Your DNA“Using a probabilistic model of genetic traits for every coordinate on the globe, the researchers have developed a method for determining more precisely the geographical location of a person’s ancestral origins.”

Early birds have the best temperament profile – but night owls have higher iqs. (~_^) – from the inductivist.

Fertile Gals Have All the Right Dance Moves“Women in the fertile phase of their menstrual cycle are judged as more attractive dancers by men than are women in a less-fertile phase, a new study finds.”

Genetically engineering ‘ethical’ babies is a moral obligation, says Oxford professor“‘Indeed, when it comes to screening out personality flaws, such as potential alcoholism, psychopathy and disposition to violence, you could argue that people have a moral obligation to select ethically better children.'” – hmmm. who’s going to go first? mightn’t their kids be at a disadvantage in some situations? see also: The wrongs, and rights, of genetic screening for children.

Sporting aggression more common in opponents of a similar ability than in contests between unequal teams“The same is also true of aggressive contests between individuals in the animal kingdom, whether it is rutting deer stags or quarrelsome Siamese fighting fish. Now scientists believe they have found evidence for the same trait in competing groups of sportsmen.”
