    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 studied Chemical Engineering at the National Autonomous University of Mexico. After that, I realized that fluids flowing in a pipe was not as interesting as studying bigger things, like oceans, mountains, clouds, and the Earth itself.

So I studied then Earth Sciences at the same University. During my master degree I focused on carbon particles in the atmosphere, where do they come from, what are they doing, are they watching us? Too many questions and just a few answers. So, I began my doctorate studies to study the flying part of particles, that is the organic composition.

MILAGRO project is important to the people in Mexico City, if we want to play soccer and see the ball in clear days with no particles and no health damages, we have to learn how to eliminate them from the air. During this project I'm going to be on the guided visits to the research sites and reporting from the field any news from scientists and the atmosphere.
