With 8 eight days to go to the opening of the 2012 London Olympics, we reflect on some scientific aspects of sport. Sports authorities will be hoping that anti-doping measures (see News Feature p. 290) are tight enough to deter and detect any cheats. But some argue that we should not try to hold the line against ‘enhancement’. If made legal, enhancement strategies could produce ‘superathletes’ (News Feature p. 287) to improve the show. Or, as part of a regime including genetic enhancement modification and rule changes, enhancement could level the playing field for competitors unlucky enough to have the wrong sort of genes (Comment p. 297). All the fuss about sport might suggest that we were born — and evolved — to run. Yes, say Michael Spedding and Tim Noakes (Comment p. 295), but at a cost. In today’s world, the physiology that got us this far makes us vulnerable to disease. Cover image: Michael Blann/Getty 6 N5 m1 `( T( H c3 N* _7 W* X \, v A: g, [# O
