Science: High-G Life

In a basement at the College of Medicine of State University of Iowa, a centrifuge whirligigs at 95 r.p.m. From 14 cages spinning about on the centrifuge come the squeaks of mice and hamsters that have spent most or all of their lives under conditions of high gravitation. Last week Physiology Professor Charles C. Wunder, who conducts the experiments, announced that his centrifuged mice have conceived, delivered and raised nine litters at up to 2Gs (the gravitational force at the earth's surface is figured at 1G; at more than 1G. earth's creatures feel heavier; at less than 1G, lighter).
