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.”

Gene distinguishes early birds from night owls and helps predict time of death“Common gene variant helps determine the time you will wake up each day — and the time of day you are likely to die.”

Link between creativity and mental illness confirmed“People in creative professions are treated more often for mental illness than the general population, there being a particularly salient connection between writing and schizophrenia.” – via parapundit.

Identical Twins Are Genetically Different, Research Suggests – copy errors.

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.

Evidence for Early Hafted Hunting Technology“[E]arly humans were manufacturing hafted multicomponent tools ~200,000 years earlier than previously thought.”

The Golden Age“If people were always getting dumber, why on Earth would the scientific revolution be recent?” – greg cochran’s latest, most excellent rant. (^_^)

Einstein’s Brain“Uncommon features of Einstein’s brain might explain his remarkable cognitive abilities” – @the breviary (with appropriate and enjoyable sarcasm from mangan… (~_^) ).

Brain scans of rappers shed light on creativity“Functional magnetic resonance imaging shows what happens in the brain during improvisation.”

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.”

(note: comments do not require an email. aggressive stickleback lurking in the foliage….)

a day late. sorry! sometimes sh*t just happens. (~_^)

Ethnic disparities in breast cancer survival remain despite socioeconomic similarities“All-cause survival was worse for African-Americans and better for Latinas and Asian-Americans compared with non-Latina whites after adjusting for age, study and tumor characteristics. When the researchers additionally adjusted for treatment and reproductive and lifestyle factors, they found that African-Americans had similar survival rates to non-Latina whites, but the survival rates of Latinas and Asian-Americans remained better.”

Diversity may be fatal, says new government health study“[P]eople suffer less cancer and heart disease when they live among their racial or ethnic peers.” – via mangan’s.

If Smart Is the Norm, Stupidity Gets More Interesting“Human intelligence varies.” – you don’t say?! (it’s in the nyt, believe it or not!)

Do Intelligent People Drink More Alcohol? – yes. yes, we do. (*hic*)

A detour through Europe?“The lithic technology of southwestern France (c. 22,000-17,000 BP) strangely resembles that of the first paleo-Amerindians (c. 12,000). Some people speculate that early Europeans reached North America by crossing the Atlantic. The truth is even more incredible. Early Europeans spread eastward and became the ancestors not only of the Amerindians but also of East Asians.” – from peter frost.

Secular change in the B/W IQ gap (in the US) – from chuck. see also steve sailer.

Penis size and infant mortality – from the autistic nerdling epigone.

Placebo effect may be ‘down to genes’“Those with a particular version of the COMT gene saw an improvement in their health after placebo acupuncture.”

The Evolution of Female Bisexuality – from jayman.

Pitch Perfect: It’s All In The Genes” – maybe/prolly. see also you, too, can have perfect pitch!

Hispanic Bio-Diversity: A Primer – from nelson.

Smoking causes asthma in second generation offspring – epigenetic effects in rats.

Epigenetic inheritance is a wild goose chase“Epigenetics matters, but not between generations.”

Appearance-based politics: Sex-typed facial cues communicate political party affiliation – republican women more feminine looking than democrat women.

Men better multi-taskers than women: study

Who Would Win in a Fight: a Modern Human or a Neanderthal?“We beat them at evolution. But what about fisticuffs?”

The Island Where People Forget to Die“[P]eople on Ikaria were, in fact, reaching the age of 90 at two and a half times the rate Americans do. (Ikarian men in particular are nearly four times as likely as their American counterparts to reach 90, often in better health.) But more than that, they were also living about 8 to 10 years longer before succumbing to cancers and cardiovascular disease, and they suffered less depression and about a quarter the rate of dementia.”

bonus: More Intelligent Birds (Like More Intelligent Humans) Have Evolutionarily Novel Preferences

bonus bonus: Electric Bugs: New Microbe Forms Living, Deep-Sea Power Cables

bonus bonus bonus: New study sheds light on how and when vision evolved“Opsins, the light-sensitive proteins key to vision, may have evolved earlier and undergone fewer genetic changes than previously believed….”

Bits of Mystery DNA, Far From ‘Junk,’ Play Crucial Role“As scientists delved into the ‘junk’ — parts of the DNA that are not actual genes containing instructions for proteins — they discovered a complex system that controls genes. At least 80 percent of this DNA is active and needed. The result of the work is an annotated road map of much of this DNA, noting what it is doing and how. It includes the system of switches that, acting like dimmer switches for lights, control which genes are used in a cell and when they are used, and determine, for instance, whether a cell becomes a liver cell or a neuron.”

New Research Suggests Bacteria Are Social Microorganisms“The research shows that a few individuals in groups of closely related bacteria have the ability to produce chemical compounds that kill or slow the growth of other populations of bacteria in the environment, but not harm their own.” – cooooooool!

Further Testing the Pioneer Hypothesis: Canada and Russia – from jayman.

Racial and ethnic diversity spreads across the country“Another significant finding is the decline in white-dominant places, where whites make up 90 percent or more of the population. Three decades ago these places represented two-thirds of the total. Today, they are down to only one-third of the total. In their stead are a growing number of communities where minorities are a significant share of the population and often where no group is a majority.” – see also nowhere to run.

Finnish ancestors’ diet explains many modern ailments – finnish cannibals!! also: “The late arrival of agriculture in Finland is still reflected in the Finnish people. According to Markku Niskanen a researcher into archaeology at the University of Oulu, the Finnish genotype is still not adapted well to the food that was introduced through agriculture, to say nothing of industrially produced nutrition. Niskanen believes that a possible reason why we have more adult-onset diabetes than other Europeans is that we are not accustomed to eating large amounts of grain.”

Social psychologists espouse tolerance and diversity — do they walk the walk? – see also Survey finds blatant bias and discrimination against conservatives in academia.

Redebunking Ron – chuck has “marshaled evidence from no less than 14 nationally representative samples (PISA 2009, PISA 2006, TIMSS 2007, PIRLS 2006, PIRLS 2001, ADD Health, GSS, NLSY 79, NLSY 97, CNLSY, NAEP Main, NAEP Long term, High School Transcript Study, and NELS) and demonstrated beyond a doubt that the claimed Ron effect was a mirage.”

bonus: Species multiply as Earth heats up“[E]ras of warming were accompanied by increases in biodiversity.” – previously evolution likes it hot.

bonus bonus: Evolution could explain the placebo effect“The model revealed that, in challenging environments, animals lived longer and sired more offspring if they endured infections without mounting an immune response. In more favourable environments, it was best for animals to mount an immune response and return to health as quickly as possible.”

bonus bonus bonus: The birdy smell of a compatible partner“New evidence shows that birds may choose their mate with the help of smell. They prefer a dissimilar mate because this gives their young a more efficient immune system.”

bonus bonus bonus bonus: Ancient, bottom-dwelling critter proves: Newer isn’t always better“Tiny, humble rhabdopleurids have lived on the ocean floor for some 500 million years, outlasting more elaborate descendants”
