    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.

Ganymede

Ganymede was a son of Tros, first king of the classical land known as Troy. One day Jupiter caught a glimpse of the young boy as he was tending sheep on Mt. Ida, and was suddenly overwhelmed with a desire to bring Ganymede to Olympus to serve as the cup bearer of the gods. Jupiter thereby changed his shape into that of an eagle, swooped down onto the craggy slopes of Ida, and carried the boy off to Mt. Olympus, home of the gods, to serve as the cup bearer of the gods. Now it so happens that this position was already filled by Hebe,the daughter of Jupiter and his wife Juno. Once Ganymede arrived at the royal court a competition began between Hebe and Ganymede for the honor of serving the gods. Eventually Ganymede won the post, and stayed on also as the favored companion to Jupiter. To honor the events surrounding the elevation of Ganymede to "cup bearer and servant of the gods," Jupiter placed the eagle, a shape he assumed when abducting Ganymede to Olympus, into the heavens as the constellation Aquila (eagle), and immortalized Ganymede as the constellation Aquarius (water bearer).
