When a Pfiesteria outbreak in Chesapeake Bay attracted wide media attention and criticism in 1997, however, the Maryland state govern- ment responded very differently. ” Since then, two national panels of scientists have verified Burkholder’s conclusions, and both federal agencies and those in several states, including North Carolina, have set up programs to reduce nutrient pollution, detect Pfiesteria outbreaks quickly, and evaluate their effects on human health. Burkholder has received several awards for her research, including an Admiral of the Chesapeake Award from Maryland’s governor and the Scientific Freedom and Responsibility Award from the American Association for the Advancement of Science.

A chemical would have been diluted by being mixed with other substances in the plant each time he did this. The fluid from the successive plants, therefore, should have contained less and less of the original poison and should have become less able to cause disease. This weakening did not occur, however. Beijerinck therefore concluded that the “poison” was a living thing that could maintain its power by reproducing. ” Beijerinck published his conclusions about tobacco mosaic virus in 1898. His research won Denmark’s Hansen Prize in 1922; he was the first person from the Netherlands to receive this award.

32 Boyer, Herbert Wayne In the early 1970s, a graduate student in Boyer’s laboratory had discovered chemicals called restriction enzymes, which some bacteria use to protect themselves against attacking viruses. Restriction enzymes act like molecular scissors, snipping the viruses’ genetic material into pieces so that the viruses cannot reproduce. The enzymes cut DNA at any point where they find a certain sequence of bases within the DNA molecule. Boyer gave a talk about his work with restriction enzymes at a scientific meeting in Honolulu, Hawaii, in November 1972.
