Microbial ice nucleation is important biotechnology for three reasons. First, preventing ice crystal formation using deletion mutants is a way to prevent frost damage; that is, "frost-ban" Pseudomads are a marketable product. Second, stimulating snow formation on artificial ski slopes extends the season; that is, ice-nucleating Pseudomonads are another marketable product. Third, the field testing of the "frost-ban" cells on strawberry plants occasioned some of the most emotional responses to rel

Author: SIMON SILVER Department of Microbiology & Immunology University of Illinois Chicago The Luddites have mostly won during the 15 years of recombinant DNA research and debates. An FDA report concludes that bovine growth hormone presents no increased health risk. Yet the combination of building political bases and mounting irrational fear of genetic engineering means that we will probably continue to be protected from this unreal danger. Our students have questioning minds, so this compilat
