This Week's Letters

Ecological recovery after the Mount St. Helens eruption in 1980 has proceeded with minimal human interference and with notable success; however, the recovery of tropical marine ecosystems such as coral reefs after large natural disturbances "is almost invariably confounded by anthropogenic stresses." The idea that Pseudomonas aeruginosa combines the genetic strategies of mutation and recombination, evolving hypermutable and hyperrecombinant strains, to adapt to the complex and harsh environment in the lungs of cystic fibrosis patients is discussed. And the relative contributions of nongovernment and government scientists, researchers in the biotechnology industry, and policy-makers to the agricultural biotechnology debate are examined.
