    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.

People Involved in MILAGRO

What image enters your mind when you hear the word scientist? Perhaps you see Albert Einstein or a person wearing a lab coat? If so, it is time for an image update! Who are today’s scientists? What are they doing in today’s world? And, where is science being done?

One answer is the more than 300 scientists from the United States, Mexico, and several other nations who worked together to study air pollution in Mexico City. The project was called MILAGRO, and it was a field campaign that took place in 2006. During a field campaign, scientists collect data outside in the natural world. They use state-of-the-art tools on the ground, in the air, on airplanes, and even on satellites to gather the data that they need to understand the air pollution problem.

Teachers were also involved in the MILAGRO campaign. They worked side-by-side with scientists during field work. Some teachers participated because they were trained scientists. Others participated to learn. But they also participated because they wanted to share their experience with students like you. You can read the teachers’ notes about their field experience at Postcards from the Field. They are written especially for you.

Many scientists involved in MILAGRO have also written to you about themselves and the work they do. Through their stories, we hope to bring science to life and show you the important work that’s being done to understand air pollution and improve air quality.
