Sunspot region 1476, the dark patch resembling the Hawaiian Islands in the photo at left, is located near the center of the sun s face as seen from Earth but has yet to act out in any major way.

By Daniel Cressey of Nature magazine About one-quarter of seafood sold as `sustainable' is not meeting that goal, according to an analysis taking aim at the two leading bodies that grant this valuable label to fisheries. In an online paper in Marine Policy and at a conference this week in Edinburgh, UK, fisheries biologist Rainer Froese of the Helmholtz Centre for Ocean Research in Kiel, Germany, launched a stinging attack on the schemes by the Marine Stewardship Council (MSC) and the marine-conservation organization Friend of the Sea (FOS) to certify fisheries as sustainable.

In 2010, a massive, magnitude-8.8 earthquake struck the south central coast of Chile, rupturing beaches and launching a tsunami that rode inland with devastating effect. In an instant, whole sections of the coastline were transformed, with large swaths of sand and rock lifted from beneath the waves.

TOKYO (Reuters) - Japan's Mount Fuji may be sitting on a large, active fault that could trigger a magnitude-7 earthquake, changing the shape of the mountain and devastating nearby communities, the education ministry said on Thursday. A survey commissioned by the ministry found a 30-km fault beneath Japan's highest mountain, believed by many to be sacred, and research results indicate it was likely to be active, a ministry official said.

The Advanced Research Projects Agency for Energy (ARPA–E) works on a three-year cycle: Funded projects have three years to prove worthy--or not. Program directors who help fund projects such as Plants Engineered to Replace Petroleum ( PETRO ) or Batteries for Electrical Energy Storage in Transportation ( BEEST ) have three years to steer the research. And, after three years at the helm as the founding director of ARPA–E, mechanical engineer Arun Majumdar has announced that he will be stepping down in June.

We spoke about Israel s homegrown platforms for launching satellites into space; the commercial, military and scientific applications of those satellites; and whether the country has plans to return to the human spaceflight arena, almost 10 years after its first foray ended in tragedy.
