And, of course, 2003 will see the 50th anniversary of the discovery of the structure of DNA. James Watson, co-discoverer with Francis Crick, tells his tale in DNA: The Secret of Life (Heinemann, April), and science writer Victor McElheny gives an outsider’s view in James D. Watson and the DNA Revolution (Wiley, February). Save a bit of money too for Duncan Watts’s Six Degrees (W. W. Norton, February), an investigation of how closely we are all connected, Steve Strogatz’s Sync (Theia, February) and Jeffrey McKee’s Sparing Nature (Rutgers, February), which investigates the effects of human population on biodiversity.
