Bubble, Bubble, Methane is Trouble: A vast storehouse of methane under the Arctic Ocean has perforated and is starting to leak, researchers disclosed. While scientists have long been preoccupied with methane release from thawing permafrost on mainland Siberia, the underwater stores in the adjoining East Siberian Arctic Shelf are much larger, and the release of […]
The most visible class of finalists were those with ambitious plans for “kite power” — harnessing the powerful and consistent winds that blow high off the Earth’s deck. […]

Farmers in Bangladesh have long had an irrigation problem. Water is often plentiful in ponds or in the shallow water table underfoot, but getting that water onto the crops is no easy task. A solution has appeared in the form of the treadle pump, a sort of Stairmaster that pumps water. […]
