The enthusiasts for such a policy will be given further encouragement by a report in “Science” (1994;263:1128-30) of research on fruit flies showing that genetic manipulation that boosted the natural defences against reactive oxygen species prolonged their lifespans by one one third.

Avalanches kill round 150 skiers each year in the Alps. An analysis of the outcome of accidents in which 422 skiers were buried (Nature 1994;368:21) showed that the chances of survival are high (92%) for the first 15 minutes but then drop precipitately to only 30% after 35 minutes. Rescue depends, then, on the action of fellow skiers, and the message is that all skiers should be taught techniques for finding, extracting, and …
