After an atomic holocaust, insects may be the only creatures left alive for miles around. Some species can survive a radiation dose 200-300 times greater than that which would kill an elephant or a man. One explanation: cells are most susceptible to radiation damage when they are in the process of dividing. Since many insects, unlike humans, undergo no cell division during much of their lives, they are more highly resistant to radiation...
...gorges with blood. About 400 roentgens has generally been considered a lethal dose for man (see MEDICINE). But a mature kissing bug, Dr. Baldwin finds, can survive 50,000 roentgens. When he bombarded small spots on young kissing bugs with 2,000,000-volt X rays, he found the cells apparently unaffected. But when the insect ate, setting off the mechanism of cell division and molting, the latent damage appeared. The irradiated spots developed blisters and degenerated...
...mechanism of radiation damage is still little understood. In experiments, Dr. Baldwin irradiated a bug sealed inside a chamber containing nitrogen. The oxygen deficiency slowed the bug's cell division, and when it molted, the bug showed two to three times less radiation damage than bugs that were irradiated in normal air. Dr. Baldwin concluded that oxygen deficiency improved radiation resistance. Since cells in humans are continually dividing, man may never hope to achieve an insect's resistance. But Dr. Baldwin is hopeful that the study of his kissing bugs will lead to basic knowledge of how radiation...
Most important, Heller found that the chromosomes could be twisted, turned, forced into new alignments. Since chromosomes carry the genetic material that controls growth and heredity, this maltreatment often kept cells from dividing, or caused mutations. Dr. Heller's waves are so specific that a change of frequency or pulsing can limit their effect to a single kind of cell, leaving slightly different cells unaffected. Since cancer cells differ from normal cells, there is a chance (which Dr. Heller does not want to talk about) that they can be damaged by radio waves that do not hurt healthy tissue...
When Gritli Moser, a little Swiss girl, is slashed to death in the woods near her native village, all the clues point to Gunten, a peddler with an unsavory reputation. When, under third degree, he confesses to the murder and then commits suicide in his cell, the local chief of police and everyone else consider the case closed-all except Inspector Matthäi, who is sure the murderer is still at large. A childish school drawing made by Gritli before her death gives him the clue he needs, and he goes to work-alone, since the other cops will...
