• The report on athletics authorities preparing to detect “gene doping” (10 December, p 6) stated that myostatin is an enzyme. In fact, myostatin is a growth factor, not an enzyme.
• Our story on the Kinkajou projector (10 December, p 29) contained several inaccuracies: it costs $50, not the $12 we quoted; the light source is a 5-watt LED, not 6-watt; and the aim is to produce 15,000 projectors for half a million learners over the next five years, not half a million projectors. Furthermore, Kinkajous are not rodents, as we stated. They are a procyonid, which means racoon-like, but they also have prehensile tails.
