Astrobiology. Ames's proposal for lab triggers battle at NASA.

Officials at NASA's Ames Research Center in Moffett Field, California, would like to trade the use of part of their land for a new building largely dedicated to NASA's nascent astrobiology program, the core of which is a 2-year-old virtual institute based at Ames. Although some scientists applaud the idea, others say that it undermines the idea of a virtual institute and that operating costs would take money away from higher priorities. Two panels have offered conflicting opinions, which may be aired at a meeting next week.
