The latest issue of Scientific American has been released, with details and free content available at the Sciam website. Free articles available from the June 2005 issue include Michael Shermer on 9-11 conspiracy theories, the constants of physics may not be so constant, and is the obesity epidemic carrying too much weight? The cover story for this issue (which is not free) is on the possibility of ‘suspended animation’, so buy the magazine if you’re curious.
