...Gerald Fink of Cornell University spoke before a crowd of approximately 150 at the Medical School yesterday to describe his recently successful experiments in recombinant DNA research with yeast cells and the E. coli bacillus...
Despite repeated warnings from the Cambridge Experiment Review Board (CERB), a team of Harvard biologists presses on with what it calls "ground-breaking" experiments using even more obscure strains of E. coli recombinant DNA. At 11:30 on December 31, the head of the research team announces that "a cancer cure may be only fifteen minutes away." At midnight, he turns into a pumpkin...
...important step in this direction had already been taken last spring when scientists at the University of California in San Francisco succeeded in transplanting a rat insulin gene into the DNA of a laboratory strain of the bacterium Escherichia coli. The bug then multiplied into countless duplicate bacteria, each containing the insulin gene, but incapable of producing insulin. In the work announced last week, Microbiologist Herbert Boyer of the University of California, San Francisco, along with Biochemist Arthur Riggs of the City of Hope Medical Center near Los Angeles and Physiologist Wylie Vale of the Salk Institute in San Diego...
...thesis should be a learning expeience," says Irene Rosenberg '78, who is studying the structure of DNA taken from corn chloroplast into E. coli bacteria. She hopes to learn about lab techniques, and in the process, contribute information that may someday lead to benefits such as higher crop yields. "My project isn't earth-shattering, it's not cornshattering, either," she says, "but it will provide some information...
...most important reason that most geneticists and molecular biologists now oppose the legislation is a growing conviction, based on continued experiments, that current recombinant DNA research is safe. Some strains of E. coli normally reside in billions in the human intestine, a fact that encouraged the fear that new laboratory forms would spread like the plague among human beings. But research has shown that E. coli K12, which traces its ancestry to bacteria taken from a human patient at Stanford University in 1922, altered genetically during its life in the labs; among other changes, it can no longer colonize...
