Spin city. An indispensable part of the biochemist's toolkit is NMR spectroscopy, a technique for identifying molecules by the nuclear spin of their hydrogen and carbon atoms. BioMagResBank holds structural NMR data for over 1640 proteins and other biomolecules, from single amino acids to exotic neurotoxins, along with links ranging from NMR backgrounders to software and researchers' home pages.

Androids exist! And not just in movies. To follow the history and current status of efforts to make humanlike robots, consult Android World, created by a fan of the field. The site links to scores of projects, from NASA's anthropomorphic space robots to Honda's P2 robot, which weighs 460 pounds and can walk up and down stairs. Entertaining miscellanea include Isaac Asimov's three laws of robots.
