    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.
Isaac Levitan painted the landscapes of the Russian countryside during the late nineteenth century. This painting of his is called After the Rain. There are two types of clouds that make rain - cumulonimbus and nimbostratus. Do the clouds that Levitan painted look like one of these types? The broken pieces of low clouds that Levitan has painted are called "scud". They happen before or after a rainfall.

When The Sun Come After Rain, a poem by Robert Louis Stevenson

When The Sun Come After Rain

When the sun comes after rain
And the bird is in the blue,
The girls go down the lane
Two by two.

When the sun comes after shadow
And the singing of the showers,
The girls go up the meadow,
Fair as flowers.

When the eve comes dusky red
And the moon succeeds the sun,
The girls go home to bed
One by one.

And when life draws to its even
And the day of man is past,
They shall all go home to heaven,
Home at last.

- by Robert Louis Stevenson, from A Child's Garden of Verses (1850-1894, Scottish writer)
