    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.

Aphrodite and Ares

Aphrodite was the goddess of love and beauty. Aphrodite was known to the Romans as Venus. With her exquisite features and pleasant smile she attracted many suitors, gods and mortals alike. She was married to the graceless and lame Hephaestus, the god of fire. Her true love was Ares, the god of war. Their child was the beautiful goddess Harmonia.

One day while Aphrodite and Ares lay together they were caught in an invisible but strong net forged by Hephaestus, who cried out when the lovers had been ensnared:

"Zeus and all you immortals! Come quickly and see this intolerable thing, worthy of your laughter. Because I am lame Aphrodite despises me. She loves the cruel Ares because he is agile and handsome. See them both bound together in their adultery, for these cords will keep them so bound until Zeus returns the gifts I made him in order to obtain this impudent wench who cannot restrain her lust!"

The gods laughed uncontrollably.
