America’ s space agency has a legendary love of paperwork. Consequently, NASA has published over 6,000 pages about the contracts for its Crew Exploration Vehicle (CEV) , the craft that will put people into orbit around Earth, allowing them to carry out tasks such as visiting the international space station after the shuttle fleet is retired in 2010.

poppers within a few months. But now the diet drug revolution is facing a backlash. Some of the nation’s largest HMOs, including Aetna U.S. Healthcare and Prudential Healthcare, have begun cutting back or eliminating reimbursement for both pills.
