    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    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.

Cronus (Saturn)

In Greek mythology, Cronus was the son of Uranus and Gaea.He lead his brothers and sisters, the Titans, in a revolt against their father and became the king of the gods. He married his sister, the Titan Rhea.

They had a total of six children, but Cronus had a bad habit of eating his newborn children, to prevent them from one day overthrowing him as king of the gods. Finally, at the birth of her last child, Zeus(Jupiter for the Romans), Rhea tricked him into swallowing a rock instead. Zeus then eventually did overthrow his father, with the help of his brothers and sisters. The Romans adopted Cronus as the god Saturn.
