Glacial Earthquakes May Help Forecast Sea-Level Rise
Glacial earthquakes are produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. A new study of the quakes’ mechanics may give scientists a way to measure ice loss remotely and refine predictions of sea-level rise.

World’s Oldest Unused Stone Tools Found (So They Say)
Last week, it was announced that scientists had found the world’s oldest stone tools, in Kenya, dated at 3.3 million years. The precise dating of the tools was made possible by Chris Lepre and Dennis Kent of Lamont-Doherty Earth Observatory, who used periodic reversals in earth’s magnetic field to nail the timing. Now, in a…
