    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

I am a professor at SUNY Old Westbury, a small public college located 30 miles from New York City. I have been teaching chemistry here for over 25 years, and have an active research program involving undergraduate students. Those of us who work at small colleges wear many hats, and I am also the chair of Adolescence Education, one of Old Westbury’s fastest growing programs. I did my undergraduate studies in chemistry at SUNY / Binghamton and my graduate work in radiation chemistry at Ohio State University. I returned to the NY area for a postdoc at Brookhaven National Laboratory (BNL), where I am still a guest researcher during the summers. My husband is also a chemistry professor and we have one grown child who has chosen not to be a chemist.

I am interested in the fast reactions that generate pollution in the atmosphere. These are reactions that involve sunlight and naturally occurring substances such as water vapor and ozone, as well as substances emitted by human activities, such as NOx and hydrocarbons. I work closely with scientists at BNL to develop methods of detecting hydrogen peroxide (H2O2) and to interpret our field observations. Although there are only a few of these molecules in every billion molecules of air, they play an important role in making smog. We will be measuring peroxides in Pachuca, Mexico, and aboard the Department of Energy Gulfstream Research Aircraft, during March 2006. We hope these measurements will help us to understand how smog forms and how to minimize its effects on the earth.
