    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.

David Greenberg

Hi, my name is David Greenberg and I'm the Director of Technology for the Mohawk Trail Regional School District in western Massachusetts. I've been helping teachers use computers in their classrooms for the last 10 years or so. I have a Masters degree in Education and before I worked in schools, I was a computer consultant and a hardware and software designer.

Actually, that's sort of where my interest in MILAGRO comes from. I own a small company called PAX Analytics that manufactures a 'plug and play' portable air quality monitoring system, used by a number of schools around the country, so when I got a chance to participate in MILAGRO, I just couldn't pass it up.

I will be working with Paul Voss, who is a scientist at Smith College in Northampton, Massachusetts. Paul has developed this very cool balloon that can be controlled from the Internet. It carries several sensors and we will use it to see where the air pollution for which, unfortunately, Mexico City is famous, goes after it leaves the city.

I'm going to be posting to the Windows to the Universe web site and if I'm able to, I will try to upload some video footage of the exciting things we're doing in Mexico. Stay tuned!
