...recipe has long been a staple of science fiction: learn how to keep monkey brains alive after the monkeys die, then try the technique with humans. But whatever the profits of the fictional feat, such achievements would be even more rewarding to the real scientist. Now, at Cleveland Metropolitan General Hospital, researchers have taken the first long step: they have learned to keep isolated monkey brains alive...
...team led by Dr. Robert J. White takes a brain, which is about as big as a man's fist, out of a rhesus monkey's skull, retains only small bits of bone to serve as supports, and suspends the brain in an apparatus of tubes and rods. Its blood vessels are hitched to a small heart-lung machine, and fresh blood is supplied from a monkey blood bank. Delicate needles stuck in its surface al low an electroencephalograph to measure the electrical activity by which all brains do their work...
...White's monkey brains sometimes stay alive for as long as 18 hours. When they finally die, it is usually because of waste products accumulating in the blood. Soon Dr. White hopes to use an artificial kidney to clean up the blood and lengthen the brains' survival time...
Zoologists have long been satisfied with the evolutionary theory that holds that humans and monkeys are closely related. But the theorists always welcome additional evidence, and last week they got some striking chemical proof. Drs. B. H. Hoyer, B. J. McCarthy and E. T. Bolton of the Carnegie Institution demonstrated that the DNA (deoxyribonucleic acid) in human genetic material has many sections that are identical with monkey...
Other Species. Next step was to repeat the experiment with different species. Just as predicted by evolutionary theory, mouse DNA combined nicely with that of other rodents, such as rats and hamsters. But it showed much less attraction for the DNA of monkeys and cattle. Human DNA demonstrated only moderate interest in mouse, but it combined with some from a rhesus monkey almost as strongly as if the stuff came from a human. Both mouse and human showed weak interest in DNA from salmon, and almost none in that from bacteria...
