Arctic Sea Ice Coverage

A really nice data visualization of Arctic Sea Ice from 1979 - 2013.  Bonus that they used a circular layout that looks like the North Pole.  Also, the data is compelling.  That's a lot of ice gone in a very short period of time. 

Sunstone

A very determined group of researchers has found an example of the previously legendary Viking sunstone used for navigating while the sun was obscured by clouds or below the horizon.  The best and most concise article I've seen is this one at The Economist.  If there were a Nobel Prize for Archeology, this team would win it.

My Pix

    Ferry to Paros, 1986.  A small part of the Aegean Sea.  Most of the rest was identical, except the
    white foamy bits are just around the edges.  Like wrapping.
