However, a subsequent paper by Bar-Matthews and Ayalon with their American colleagues Ian Orland and John Valley studied samples from a stalagmite that apparently grew from about 200 B.C. to 1100 A.D. And that showed isotopes as low as -8.5 permil, with annual rainfall in the Roman era reaching double the amounts the scientists had previously calculated. The article, published in the 2009 issue of Quaternary Research, was submitted for publication on October 11, 2007, before Bar-Matthews and Ayalon gave evidence at the ossuary trial...
...year-old woman who has such severe damage to her amygdalae - due to a rare genetic condition called Urbach-Wiethe disease, which causes calcification in the temporal lobes - that they have stopped functioning. The patient's identity isn't public, but neuroscientists call her SM, and a new paper in the journal Nature Neuroscience reports the results of experiments judging her conception of personal space...
Because the new paper is mostly based on one unusual subject, it shouldn't be overinterpreted. But the findings may have relevance for research into autism, whose sufferers sometimes have trouble understanding personal space and are thought to have amygdalae impairment. Previous studies of SM show that her brain impairment makes it difficult for her to recognize expressions of fear or judge a person's trustworthiness - problems that are also common among people with autism. Researchers think people who suffer from extreme shyness may turn out to have a problem in their temporal lobes as well. There's no known...
...maybe the argument is flawed. New research by David Barker of the University of Iowa and Eric Miller of the Congressional Budget Office indicates that homeownership actually has little to no effect on how kids do in school. Their paper, "Homeownership and Child Welfare," which appears in the summer issue of Real Estate Economics, is drumming up interest in housing-policy circles for calling into question one of the basic rationales for encouraging people to own homes. It's yet another idea - like house prices always go up, and down payments aren't that important - being re-evaluated...
...paper just published in PLoS ONE - a journal of the Public Library of Science - a team led by psychiatrist Gregory Berns of Emory University in Atlanta shows that adolescents who engage in more dangerous activities have white-matter pathways that appear more mature than those of risk-averse youths. White matter is essentially the brain's wiring - the neural strands that connect the various gray-matter regions, where the actual nerve cells reside, that are otherwise independent of one another. Maturation of white matter is important because it increases the brain's processing speed; nerve impulses travel faster in mature...
