    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.

Europa

The full moon is so fierce that I can count the
coconuts' cross-hatched shade on bungalows,
their white walls raging with insomnia.
The stars leak drop by drop on the tin plates
of the sea almonds, and the jeering clouds
are luminously rumpled as the sheets.
The surf, insatiably promiscuous,
groans through the walls; I feel my mind
whiten to moonlight, altering that form
which daylight unambiguously designed,
from a tree to a girl's body bent in foam;
then, treading close, the black hump of a hill,
its nostrils softly snorting, nearing the
naked girl splashing her naked breasts with silver.
Both would have kept their proper distance still,
if the chaste moon hadn't swiftly drawn the drapes
of a dark cloud, coupling their shapes.

She teases with those flashes, yes, but once
you yield to human horniness, you see
through all that moonshine what they really were,
those gods as seed-bulls, gods as rutting swans
an overheated farmhand's literature.
Who ever saw her pale arms hook his horns,
her thighs clamped tight in their deep-plunging ride,
watched, in the hiss of the exhausted foam,
her white flesh constellate to phosphorous
as in salt darkness beast and woman come?
Nothing is there, just as it always was,
but the foam's wedge to the horizon-light,
then, wire-thin, the studded armature,
like drops still quivering on his matted hide,
the hooves and horn-points anagrammed in stars.

--Derek Walcott, 1981
