Born to run: genetic test can reveal those best able to run marathons – “[T]o run a marathon in a good time requires the right combination of genes and that nearly a fifth of the population lack this special mix. For runners with the right genes, it means their bodies can quickly adapt to carry large amounts of oxygen to their muscles, allowing them to run faster and for longer. Those who lack these genes, however, will never improve, no matter how much they train, and their performance may even get worse the harder they push themselves.”
Scientists Breed Exercise-Crazy Rats – “While a wide biological gap exists between humans and rats, the researchers do propose that some people could be genetically predisposed against exercising.”
New Studies Shake Up Human Family Tree – “[I]n a spate of new studies, paleoanthropologist Lee Berger, of the University of the Witwatersrand, and a team of collaborators have put forward a controversial claim that another hominin — *Australopithecus sediba* — might be even closer to the origin of our lineage [than *australopithecus afarensis,* the most famous example being “lucy”]….” — see also: Special Collection – Australopithecus sediba @science.
Castaways – “We may have yet another story of long-distance prehistoric contact. A new paper in PLOS genetics suggests that people from the Jomon culture in Japan may have reached northwestern South America.” – from greg cochran. also from south america: Southern Native American Y-DNA: no correlation with language – @for what they were…we are.
Fluctuation of Fertility with Number in a Real Insect Population and a Virtual Population – “Real fruit fly fertility increases with average consanguinity thus decreasing with population size in a pattern that is modelled successfully with a virtual population. This invites the deliberate manipulation of wild insect populations for the control of vectors of human disease.” – from our very own linton herbert! yay! (^_^)
Do drugs for bipolar disorder ‘normalize’ brain gene function? U-M study suggests so – “Brain tissue study shows gene expression in patients treated with antipsychotics is similar to expression in non-bipolar brains.”
Serenity – “If the realities of human nature render your hope on how to make a better world impossible, merely wishing it were not so is not going to help your cause. But instead, better results can be attained to by working *with* what we learn about human nature.” – from jayman. hear, hear!

Study: we assume people stare at us – “People often think that other people are staring at them even when they aren’t, vision scientists have found. In a new article in Current Biology, researchers at The Vision Centre reveal that, when in doubt, the human brain is more likely to tell its owner that they’re under the gaze of another person.”

Our Inconsistent Ethical Instincts – read also: The Pro-Death Movement from jim goad – “[T]here’s an almost universal human definition of good and evil: If it enhances my survival, it’s good. If it harms it, it’s evil.” – yup.
Individual Donation Amounts Drop When Givers Are in Groups, Says MU Researcher – “Numerous studies have provided evidence that people are less likely to help when in groups, a phenomenon known as the ‘bystander effect.'” – see also this old post from steve sailer: Chinese kindness.
The Fraud Of America’s “Rape Culture” – from anatoly. see also his earlier post Much Ado About Rape: Quantifying A Big Taboo – “[I]t is ironic that the public panic over rape and sexual assault has risen to fever pitch at precisely the moment in history when the real lifetime risk of becoming a victim of rape has never been lower.”
How Parents Around the World Describe Their Children, in Charts – “A fascinating new study reveals that Americans are more likely to call their children ‘intelligent,’ while European parents focus on happiness and balance.”
