    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.

Florence Bascom

Florence Bascom was one of the first female geologists in the United States and her fellow scientists thought she was one of the nation’s most important geologists. She lived from 1862 until 1945 and is well known for her work at Bryn Mawr College where she taught for many years.

Bascom studied mineral crystals by looking at them with a microscope. She also studied metamorphic rocks, how mountains form, and how rocks from mountain erode into sand. At the time she went to college, it wasn’t easy for a woman to go to study for advanced degrees in the United States. But that didn’t stop Florence Bascom! She earned two bachelor’s degrees and a master’s degree from the University of Wisconsin and a Ph.D. in geology from Johns Hopkins University. She was the second woman to ever earn a Ph.D. in geology in the United States.

Florence started teaching geology at Bryn Mawr, a women’s college, in 1895. She collected minerals, rocks, and fossils for the college and taught hundreds of students over the years, many of whom became successful geologists too!
