Scientist at Work: Michael Muehlenbein

Michael Muehlenbein Everybody wants to hold the cute baby monkey, at least until Michael Muehlenbein informs the travelers who've paid thousands of dollars to get close to orangutans, macaques and other primates on the island of Borneo that all but one of the top dozen serious emerging diseases on the planet are zoonotic -- that is, diseases that originate from nonhuman animals. You can believe that Muehlenbein, an assistant professor with Indiana University's Department of Anthropology, is doing you a favor when he kindly scolds, "There is rarely a good reason to hold a monkey."  Full Story

Communication trumps penalties in new study of social-ecological systems

Ostrom SES grid

Research conducted in a virtual world by Indiana University Bloomington and Arizona State University scientists, including recent IU Bloomington Nobel laureate Elinor Ostrom, shows how common-pool resources -- such as fisheries, forests, water systems or even bandwidth -- can be managed effectively by self-organized user groups under certain conditions. The findings were published April 30 in the journal Science.

Natural selection for moderation in testosterone surprises scientists

Junco

A field study of the relationship between testosterone and natural selection in an American songbird, the dark-eyed junco, has defied some expectations and confirmed others. Scientists from Indiana University Bloomington, the University of Virginia, Indiana University-Purdue University Indianapolis, and the University of Southern Mississippi report in the June issue of The American Naturalist that extreme testosterone production -- high or low -- puts male dark-eyed juncos at a disadvantage in both survival and reproduction outside their semi-monogamous breeding pairs.

Policy changes needed to protect southeast Mexico's farmers, forests

Campeche reforestation

If it is to ensure a bright future for Campeche farmers and the tropical forests surrounding them, the Mexican government must institute new policies that are more responsive to economic and ecological realities, an Indiana University Bloomington geographer argues. In a recent issue of the Proceedings of the National Academy of Sciences, Rinku Roy Chowdhury says this diversity is not addressed directly or indirectly by Mexico's laws or policies in the region, calling into question whether those policies are effective.

Physicist finds colder isn't always slower as electron emissions increase at temps down to -452 F

Hans-Otto Meyer

Science is detective work so it was not unexpected that new questions would follow old ones as Indiana University Bloomington nuclear physicist Hans-Otto Meyer's work progressed on testing a fundamental symmetry of nature that could lead to understanding the matter-antimatter asymmetry in the universe. But while searching for a non-zero separation of positive and negative charge inside a neutron (the symmetry-violating nEDM), Meyer ran into another mystery scientists have yet to explain.
