Plants growing at the bottom of sinkholes in China's Dashiwei Tiankeng Group don't take up as much carbon as surface plants do, but they have much higher levels of nutrients in their tissues.

A buildup of methane and other fluids in open and closed "systems" in the permafrost could explain why strange, icy mounds sometimes erupt to form giant crater, researchers say.

An air taxi has completed the first forward flight of a hydrogen-fueled aircraft capable of vertical takeoff and landing — and it broke a distance record in the process.

Lake Kivu, one of the African Great Lakes, sits along a tectonic plate boundary called the East African Rift, which is dotted with hot springs that feed carbon dioxide and methane into the water.
