Is autism more common in Silicon Valley?A new study from Simon Baron-Cohen and colleagues asked pretty much this question, although rather than California, they looked at Eindhoven in Holland. Eindhoven is the tech hub of the Netherlands:This region contains the Eindhoven University of Technology, as well as the High Tech Campus Eindhoven, where IT and technology companies such as Philips, ASML, IBM and ATOS Origin are based... 30% of jobs in Eindhoven are now in technology or ICT, in Haarlem an........

Pottery is the most important type of artifact for archaeology in the Southwest. This is because the agricultural societies of the prehistoric Southwest made huge numbers of pots and often decorated them in distinctive ways that differed both from place to place and over time, often within quite short periods. With the precision available from [...]... Read more »
We usually think of farmers as sturdy, Midwestern types who raise their ruddy-cheeked children on a balanced diet of eggs, potatoes, and chores. A study from researchers at Emory University, though, suggests that our farming ancestors weren't the picture of health. When humans transitioned from hunting and gathering to farming and living in cities, the authors say, they became malnourished and more prone to disease. Oh, and they were shorter.Scientists use height as a rough yardstick of a popula........ Read more »

Southwestern archaeology, especially in the Chaco area, is structured chronologically primarily by the Pecos Classification. This system was initially worked out at the first Pecos Conference in 1927, and it was originally interpreted as a series of stages in cultural development, with the assumption that sites with similar characteristics and material culture were roughly contemporaneous.

The journal Applied Geography and the journal Land Use Policy have recently published two papers, “Spatiotemporal modeling of the expansion of mechanized agriculture in the Bolivian lowland forests” and “Deforestation dynamics and policy changes in Bolivia’s post-neoliberal era” respectively, that depict a desolating panorama. The rate of deforestation under Evo Morales’ government is even higher than it was during the previous governments. Muller et al. say that “While overall dyn........ Read more »

Last year, I discussed the controvery over the proposed new childhood syndrome of "Temper Disregulation Disorder with Dysphoria" (TDDD). It may be included in the upcoming revision of the psychiatric bible, DSM-V.Back then, I said:TDDD has been proposed in order to reduce the number of children being diagnosed with pediatric bipolar disorder... many people agree that pediatric bipolar is being over-diagnosed.So we can all sympathize with the sentiment behind TDDD - but this is fighting fire wit........

What does it mean to be monogamous?Sexual exclusivity between two partners?

Or is it perhaps some combination of these four?

Two articles published last month in the American Journal of Physical Anthropology are starting to greatly complicate bioarchaeologists' use and interpretation of stable oxygen isotope ratios in an attempt to understand migration and mobility in the past. Science is constantly progressing, and it can be challenging to keep up with the latest research. The real challenge for me, though, is in interpreting the isotope analyses I have done on populations from Imperial Rome - first becau........ Read more »

As any fan of the adventures of Daredevil, being blind in comic books can give you superpowers. Matt Murdoch was blinded by a radioactive accident that he befell because he tried to save a blind pedestrian from the truck carrying the waste (ah, the irony…). Murdoch developed a kind of ‘radar’ sense that allowed him to prowl Hell’s Kitchen, rooting out the miscreants and lowlifes who, like the blind Man Without Fear, preferred to lurk in the dark.
