linkfest – 03/24/13

extra-long [insert dongle joke here] linkfest this week since there wasn’t one last sunday (sorry, dog ate it…). note that there (probably) won’t be one next sunday either, ’cause i’ll be too busy hunting for easter eggs…. (^_^)

Common DNA Markers Can Account for More Than Half of the Genetic Influence on Cognitive Abilities“In the same sample of 3,154 pairs of 12-year-old twins, we directly compared twin-study heritability estimates for cognitive abilities (language, verbal, nonverbal, and general) with GCTA estimates captured by 1.7 million DNA markers. We found that DNA markers tagged by the array accounted for .66 of the estimated heritability, reaffirming that cognitive abilities are heritable. Larger sample sizes alone will be sufficient to identify many of the genetic variants that influence cognitive abilities.” – via race/history/evolution notes.

Genotypes over-represented among college students are linked to better cognitive abilities and socioemotional adjustment“The present study investigated … genotype frequencies of 284 SNPs covering major neurotransmitter genes in a sample of 478 Chinese college students, comparing these frequencies with those of a community sample (the 1000 Genomes dataset)…. Results showed that 24 loci showed Hardy–Weinberg disequilibrium among college students, but only two of these were in disequilibrium in the 1000 Genomes sample. These loci were found to be associated with mathematical abilities, executive functions, motivation, and adjustment-related behaviors such as alcohol use and emotion recognition.” – via … somebody … can’t remember who. sorry!

Why Bacteria Commit Suicide“[I]nfected individuals self-destructed before they could spread the virus to others.”

Evolution via Roadkill“Cliff swallows that build nests that dangle precariously from highway overpasses have a lower chance of becoming roadkill than in years past thanks to a shorter wingspan that lets them dodge oncoming traffic. That’s the conclusion of a new study based on 3 decades of data collected on one population of the birds. The results suggest that shorter wingspan has been selected for over this time period because of the evolutionary pressure put on the population by cars.”

‘Out of Africa’ Story Being Rewritten Again“Our early human ancestors may have left Africa more recently than thought, between 62,000 and 95,000 years ago, suggests a new analysis of genetic material from fossil skeletons.” – see also Mitochondrial DNA tree calibrated with ancient DNA @race/history/evolution notes and Revised timescale of human mtDNA evolution from dienekes.

Did evolution give us inflammatory disease?“[S]ome variants in our genes that could put a person at risk for inflammatory diseases such as multiple sclerosis, Crohn’s disease or rheumatoid arthritis, have been the target of natural selection over the course of human history.” – original research article.

Genes may be reason some kids are picky about food“The study looked at 66 pairs of twins between ages 4 and 7 years old, and found that genes explain 72 percent of the variation among children in the tendency to avoid new foods, while the rest was influenced by environment.”

Was inbreeding common among early humans? 100,000-year-old deformed skull adds evidence to theory of ‘very small’ communities“The discovery adds to growing evidence that early humans inbred often” – prolly because populations were small. see also Abnormalities in Pleistocene Homo from dienekes.

NATIONAL ANTHEMS AND SUICIDE RATES

“In a sample of 18 European nations, suicide rates were positively associated with the proportion of low notes in the national anthems and, albeit less strongly, with students’ ratings of how gloomy and how sad the anthems sounded, supporting a hypothesis proposed by Rihmer.

“‘For most of the 20th Century, Hungary had the highest suicide rate in the world and, also, among immigrants to the United States, Hungarians had the highest suicide rates (Lester, 1994). Hungary is also known for the ‘suicide song’ — ‘Gloomy Sunday‘ — which was written by a Hungarian (Rezso Seress) in 1933 and which was banned from radio stations since it seemed to induce people to commit suicide (Stack, Krysinska, & Lester, 2007–2008). Rihmer (1997) noted that the Hungarian national anthem was very sad and, in an informal study of suicide rates in European nations, declared that higher national suicide rates were associated with more low notes in national anthems….

“Male and female suicides rates were weakly associated with the ratings of gloomy (Pearson rs = .30 and .42, respectively, one-tailed ps = .11 and .04), with the ratings of sad (rs = .23 and .40, respectively, ps = .18 and .05), and with the proportion of low notes (r = .63 and .54, respectively, ps = .003 and .01). The proportion of low notes was associated with the ratings of gloomy and sad (rs = .52 and .44, ps = .02 and .04, respectively). Thus, Rihmer’s suggestion was supported by the present analysis….”

cheery lyrics to the hungarian national anthem, too:

Himnusz

O Lord, bless the nation of Hungary
With your grace and bounty
Extend over it your guarding arm
During strife with its enemies
Long torn by ill fate
Bring upon it a time of relief
This nation has suffered for all sins
Of the past and of the future!

You brought our ancestors up
Over the Carpathians’ holy peaks
By You was won a beautiful homeland
For Bendeguz’s sons
And wherever flow the rivers of
The Tisza and the Danube
Árpád our hero’s descendants
Will root and bloom.

For us on the plains of the Kuns
You ripened the wheat
In the grape fields of Tokaj
You dripped sweet nectar
Our flag you often planted
On the wild Turk’s earthworks
And under Mátyás’ grave army whimpered
Vienna’s “proud fort.”

Ah, but for our sins
Anger gathered in Your bosom
And You struck with Your lightning
From Your thundering clouds
Now the plundering Mongols’ arrows
You swarmed over us
Then the Turks’ slave yoke
We took upon our shoulders.

How often came from the mouths
Of Osman’s barbarian nation
Over the corpses of our defeated army
A victory song!
How often did your own son agress
My homeland, upon your breast,
And you became because of your own sons
Your own sons’ funeral urn!

The fugitive hid, and towards him
The sword reached into his cave
Looking everywhere he could not find
His home in his homeland
Climbs the mountain, descends the valley
Sadness and despair his companions
Sea of blood beneath his feet
Ocean of flame above.

Castle stood, now a heap of stones
Happiness and joy fluttered,
Groans of death, weeping
Now sound in their place.
And Ah! Freedom does not bloom
From the blood of the dead,
Torturous slavery’s tears fall
From the burning eyes of the orphans!

Pity, O Lord, the Hungarians
Who are tossed by waves of danger
Extend over it your guarding arm
On the sea of its misery
Long torn by ill fate
Bring upon it a time of relief
They who have suffered for all sins
Of the past and of the future!
