Frosty Gullies on the Northern Plains of Mars

Seasonal frost commonly forms at middle and high latitudes on Mars, much like winter snow on Earth. However, on Mars most frost is carbon dioxide (dry ice) rather than water ice. This frost appears to cause surface activity, including flows in gullies. via NASA http://ift.tt/1LZCz3H

U.S. Foreign Policy: Inept, or Something Else?

The Contrary Perspective

"Possible explanations can become needlessly complex. It is coherent, for instance, to add the involvement of leprechauns to any explanation, but Occam's razor would prevent such additions unless they were necessary."

We were about to reelect a president, Woodrow Wilson, precisely because he had kept the country out of World War I. With the exception of the Navy, the U.S. military was small, and few Americans (Teddy Roosevelt comes to mind) boasted about the “manly” virtues of military service and war.

Here we are, a century later, in a country that has taken up militarism, a country which is increasingly reactionary, authoritarian, and backward-leaning, a country that leads the world not in innovation for ordinary people as in the days of Edison and Ford, but in weapons exports to the world’s trouble spots.
