The Biosphere 2 terrarium in the Arizona desert once again has a research life, after surrounding land was sold recently for housing. The University of Arizona at Tucson announced on 26 June that it would lease the 16-hectare Biosphere 2 complex for three years to conduct environmental studies. Researchers hope to use the 1.4-hectare dome with an enclosed pond and vegetation for ecological studies.
