Longitude and longevity

In the wake of a special section about "tropospheric processes," readers discuss the influences of natural events and human activity. Researchers produce data that might "decrease the anxiety" of fathers who sire children before the age of 45. Biologists review the status of "a national biodiversity inventory" in Costa Rica. Scientists revisit the challenge of conducting "expensive, long-term" therapeutic drug research and development. And "the reality" of science administration in Britain is explicated.
