My students are always surprised when they meet us at the grocery store! Yes, professors are people too!

Here is what I am reading today:

“Ionizing radiation is the primary environmental risk factor for developing meningioma, which is the most frequently diagnosed primary brain tumor in the United States. Dental x-rays are the most common artificial source of exposure to ionizing radiation for individuals living in this country.”

“Research by psychologists at the University at Buffalo and the University of California, Irvine, has found that at least part of the reason some people are kind and generous is because their genes nudge them toward it.

Michel Poulin, PhD, assistant professor of psychology at UB, is the principal author of the study “The Neurogenics of Niceness,” published in this month in Psychological Science, a journal of the Association for Psychological Science.

The study, co-authored by Anneke Buffone of UB and E. Alison Holman of the University of California, Irvine, looked at the behavior of study subjects who have versions of receptor genes for two hormones that, in laboratory and close relationship research, are associated with niceness. Previous laboratory studies have linked the hormones oxytocin and vasopressin to the way we treat one another, Poulin says.”

“The study, coming seven months after the start of the Occupy Wall Street Movement, which has been aimed at addressing income inequality, was conducted by researchers from: New York University’s Wilf Family Department of Politics; the University of Toronto; the University of California, San Diego; the University of California, Davis; and the University of Nebraska, Lincoln.

Previous scholarship has established that two areas of the brain are active when we behave in an egalitarian manner—the ventromedial prefrontal cortex (vmPFC) and the insular cortex, which are two neurological regions previously shown to be related to social preferences such as altruism, reciprocity, fairness, and aversion to inequality. Less clear, however, is how these parts of the brain may also be connected to egalitarian behavior in a group setting.”
