razib | May 27, 2009The first is for science weblog posts. Nominations end the 1st of June. Steven Pinker is picking the winner out of 6 finalists.
razib | May 27, 2009Scientific American has a long piece reviewing the recent genetic insights into the origins and development of the most awesome pets of all:
It is by turns aloof and affectionate, serene and savage, endearing and exasperating. Despite its mercurial nature, however, the house cat is the most popular pet in the world. A third of American households have feline members, and more than 600 million cats live among humans worldwide. Yet as familiar as these creatures are, a complete understanding of their origins has proved elusive. Whereas other once wild animals were domesticated for their milk,…

razib | May 26, 2009Kambiz of Anthropology.net is back. His first offering reports on a new paper on the evidence for leprosy in India 4,000 years ago.
...Lots of hallmarks in human existence occurred during this time period, some being inventions in system of writing, standardized weights and measures, monumental architecture, and trade networks that stretched to Mesopotamia and beyond. While the pathophysiology of leprosy is up in the air, it is not surprising that communicable diseases, even not very contagious ones like leprosy, also blossomed during the rapid sedentarisation of human populations.
Well, I…
razib | May 26, 2009In light of my post on politics and personal perspective yesterday, I thought this "exchange" between Mark Levin and Conor Friedersdorf would be of note. Also see Rod Dreher on the controversy. In any case, here you have a case where the principals agree on the broad political issues at stake, and many of the specifics as well, but disagreemants over style lead Levin to takfir his critics. In fact, if you read the comments at the first link it's clear that Friedersdorf's point is basically unintelligible to many fans of Levin.
razib | May 26, 2009On this week's Science Saturday John Horgan interviews Richard Wrangham. The second half of the conversation focuses on Wrangham's new book, Catching Fire: How Cooking Made Us Human. I've heard pieces of the arguments mooted in the back & forth before, but it looks like in this book they're all brought together. Humans are a large animal with a very small gut, so we need to maximize the bang-for-the buck when it comes to what we eat. Unlike gorillas and to a lesser extent chimpanzees we just aren't able to process enough low quality vegetable matter to keep ourselves going. Part of this…
razib | May 26, 2009The Onion presents an interesting spin on the financial retrenchment that's in vogue right now. I do wonder it's really the best for the real estate sector, as it seems like it would reduce aggregate demand for rental units. Also, note the shout out to Robert Ingersoll.

razib | May 25, 2009Brian Switek of Laelaps has an op-ed in on Ida. Here's the conclusion:
What could have been a unique opportunity to communicate science has quickly developed into a fiasco. Science proceeds through discovery and debate, and hypotheses do not become accepted by flooding the media with press releases. Scientific scrutiny of Ida has only just begun, and regardless of who her closest living relatives are, I hope the debate surrounding her will not sink away from sight. She truly is an amazing find, but for now I think that she has taught us more about science communication than our ancestry.
It…
razib | May 25, 2009Why We Stare, Even When We Don't Want To:
"When a face is distorted, we have no pattern to match that," Rosenberg said. "All primates show this [staring] at something very different, something they have not evolved to see. They need to investigate further. 'Are they one of us or not?' In other species, when an animal looks very different, they get rejected."
And so, we stare. (An averted gaze is triggered in some people. This too can be overridden only with great difficulty.)
It doesn't take much of a facial anomaly to trigger a transfixed response; a normal human face upside down will do it…
razib | May 25, 2009Dienekes points me to new research on MHC and mating:
The scientists studied MHC data from 90 married couples, and compared them with 152 randomly-generated control couples. They counted the number of MHC dissimilarities among those who were real couples, and compared them with those in the randomly-generated 'virtual couples'. "If MHC genes did not influence mate selection", says Professor Bicalho, "we would have expected to see similar results from both sets of couples. But we found that the real partners had significantly more MHC dissimilarities than we could have expected to find simply…
razib | May 25, 2009The Neurocritic points me to a paper, The brain structural disposition to social interaction:
Social reward dependence (RD) in humans is a stable pattern of attitudes and behaviour hypothesized to represent a favourable disposition towards social relationships and attachment as a personality dimension. It has been theorized that this long-term disposition to openness is linked to the capacity to process primary reward. Using brain structure measures from magnetic resonance imaging, and a measure of RD from Cloninger's temperament and character inventory, a self-reported questionnaire, in 41…
razib | May 25, 2009Andrew Gelman has a post up titled Difficulties in trying to understand the views of others, responding to a Robin Hanson taxonomy outline the motivations of liberals, conservatives and libertarians. Gelman is skeptical of Hanson's glosses of each group.
The human ability to engage in Meta-Representation is one of the hallmarks of our species. We can analyze abstract ideas, take the positions of others, examine counter-factuals and what-if's. In terms of core competencies our Theory of Mind is a sharp knife, we are unparalleled at modeling social relations contingent upon the mental states of…
razib | May 24, 2009A quick note. Two new ScienceBlogs: Christina's LIS Rant & Confessions of a Science Librarian. Also, Afarensis, John Lynch and John Wilkins have new locations.
razib | May 24, 2009Waves of stationary shape:
Over at Scienceblogs, people are talking about waves. Of course, everyone thinks that waves are in the domain of physics, and people always forget about one of my favorite subjects: waves of advance. Way back in the day, RA Fisher wondered what might happen if genes had to spread not just locally but across space, and he published his findings in a landmark article called The Wave of Advance of Advantageous Genes. This paper was not just important for its contributions to population genetics, but because of fundamental contributions to applied mathematics. As far as…

People By Nature Are Universally Optimistic, Study Shows:
Data from the Gallup World Poll drove the findings, with adults in more than 140 countries providing a representative sample of 95 percent of the world's population. The sample included more than 150,000 adults.
Eighty-nine percent of individuals worldwide expect the next five years to be as good or better than their current life, and 95 percent of individuals expected their life in five years to be as good or better than their life was five years ago.

At the country level, optimism is highest in Ireland, Brazil, Denmark, and New…
razib | May 22, 2009Megan McArdle posts Edmund Andrews' response to her revelation of his wife's bankruptcies. Megan concludes:
On a very broad note, I don't see this as a story about the goodness or badness of Andrews or Barreiro--and I've been dismayed by some of the nastiness about her in comments here and elsewhere. Rather, I think this matters because the story Andrews told was basically about the subprime crisis, and the book casts him as a sort of everyman, lured in by cheap credit and a likeable scoundrel of a mortgage broker. That may be what happened to many, or most people in the mortgage crisis--…
razib | May 22, 2009It is well known that different ethnic groups vary when it comes to diseases such as Type II Diabetes. Or, more specifically they vary in terms of risk, all things equal (if you use an online Type II Diabetes calculator you'll see immediately as they sometimes have a parameter for ethnicity). American blacks for example are heavier than American whites. This seems to be true even when you control for socioeconomic status (though as Oprah once said, "You don't need to do a 'study' to figure that out"). There has been research on genetic loci correlating to obesity in European populations…
razib | May 21, 2009Most people have probably read Edmund Andrews' piece in The New York Times, My Personal Credit Crisis (expanded into the book Busted: Life Inside the Great Mortgage Meltdown). Many raised eyebrows when reading this:
We had very different ideas about money. Patty spent little on herself, but she refused to scrimp on top-quality produce, Starbucks coffee, bottled juices, fresh cheeses and clothing for the children and for me. She regularly bought me new shirts and ties to replace the frayed and drab ones in my closet. She thought it wasn't worth agonizing over nickels and dimes. I was almost…
razib | May 21, 2009A few years ago I commented a fair amount on the topic of prosopagnosia, face blindness. Turns out that ~2% of the population can't really recognize faces, and this is a cryptic trait as many of these individuals have developed compensatory tendencies so that people don't know. Not only that, but there seems to be a strong genetic component so that it runs in families. At the time I was fascinated by this because it made me wonder at how much more "cryptic" variation there could be in the human population. It seems that face recognition is such a basic and universal "competency" that it is…
