Likewise, Walter Gilbert, American Cancer Society Professor of Molecular Biology, has been forced to cancel his talk on "Proinsulin from Bacteria" scheduled for this afternoon at 5 p.m. in room 18, 2 Divinity Ave. Al Vellucci, the former mayor of Cambridge, who is known for his strong support of recombinant DNA research, could not be reached for comment...
...experimentation is potentially hazardous largely because of its unpredictability; an experiment could result in bacteria which produce insulin or the creation of new strains of dangerous bacteria that resist antibiotics. Often, the DNA is inserted into the E. coli bacteria, which live in the human gut, but if these hybrid organism were to escape from the laboratory, they could enter the human body and resist its normal immunological defenses. To their credit, scientists engaged in this research were the first to sound the alarm in the early '70s. Lear traces the chain of events that led to regulation...
Arber, 49, first postulated the existence of restriction enzymes in the early 1960s while studying viruses that invade bacteria. After labeling a virus with a radioactive isotope that acted as a tracer, Arber found that when the virus entered a bacterium, most of the viral DNA was destroyed...
...ocean some people began to care. It was a thick, black, foul-smelling mass of sludge--described as "black mayonnaise"--perhaps 100 square miles in area. No one knew how deep. It came drifting back to the New York shoreline with a number of noxious odors and bacteria. Fortunately, disease and severe hardship was avoided because the threat was detected early.
