Yesterday, one of the grandest experimental fusion reactors in the world flared to life, converting hydrogen into a plasma for less than a second. The honor of pressing the button went to a PhD in Quantum Chemistry (who also happens to be the Chancellor of Germany), Angela Merkel.
In 1974, the mayor of Hammerfest, Norway declared that his small fishing community—the northernmost town in the world—would one day become the center of the oil and gas industry in the Barents Sea.

On Friday, Department of the Interior secretary, Sally Jewell, announced the Obama administration's plans for stopping all new leases on federal lands for coal mines. This down time will give the DOI the chance to review the government's coal program and better account for the environmental costs of burning coal with a programmatic environmental impact statement.
