This Week's Letters

Toothpick use is not unique to hominids--it is noted that chimpanzees use toothpicks as well. The contribution of international family planning and reproductive health programs to the "health and wealth of nations" is discussed. Database searches for literature related to adverse health effects of genetically modified (GM) foods reveal few citations: "If...safety and toxicity studies of GM foods have been carried out...why have the results not been subjected to the judgment of the international scientific community...[through publication] in reputed journals?" And the history of the design and development of late-metal catalysts for the production of polyolefins ("plastics") is outlined.
