...another type of bacterial enzyme, called a ligase (from the Latin word meaning to bind), which acted as a form of genetic glue that could reattach severed snatches of DNA. Using their new biochemical tools, the scientists embarked upon some remarkable experiments. As usual, they turned to their favorite guinea pig, a lab strain of E. coli, and soon they had learned to insert with exquisite precision new genetic material from other, widely differing organisms into the bacteria (see diagram...
...whom former U.N. Ambassador Daniel P. Moynihan called "the Gurkhas of the Russian empire." Besides the approximately 13,000 Cuban troops and 4,000 advisers in Angola, Western intelligence sources believe that Havana now has military and/or civilian advisers in the Congo (Brazzaville) (2,000), Sierra Leone (200-300), Guinea (300-500), Equatorial Guinea (300-500), Guinea-Bissau (300), Mozambique (500-600), Tanzania (500), Somalia (650) and, for the past month or so, Uganda (about 100). In Mozambique the Cubans help with sugar growing and perhaps with the training of Rhodesian guerrillas. In Somalia, on the Horn of Africa, they...
Scientists themselves, like many of those at Denver, have been increasingly questioning their own role. Protesting science's callous use of human guinea pigs for experimentation, Dr. Richard M. Restak, a Washington neurologist, decries the fact that the prestigious National Institutes of Health refused to establish a code governing such experiments until its sponsored researchers were found guilty of injecting live cancer cells into uninformed subjects. Writing on the Op-Ed page of the New York Times, Restak voiced "a creepy realization that when left to their own devices, biomedical scientists are capable of some rather nasty mischief indeed...
Telltale Symptoms. As a first step, he inoculated his guinea pigs with lung tissue from two victims of Legionnaires' disease. Within a day or so, the lab animals developed telltale symptoms: fever, lethargy, watery eyes. Then McDade injected material from their spleens into chick embryos, which also became infected, and died within six days...
...guinea pigs' blood was then injected into fertilized egg yolks. Subsequent tests linked the bacteria to the earlier St. Elizabeth cases...
