...half to form a big box with glassed-in ends. Perched on a concrete pedestal 6 ft. off the ground, the whole thing resembles nothing so much as a huge television set. The glass in the picture windows is specially treated to let in ultraviolet rays so that on sunny days the occupants can indulge in the Russian penchant for midwinter sunbathing. Looking in on such a scene, passers-by might well wonder what channel that show was coming...
Bjorklund vaccine is made by grinding up cancer cells and irradiating them with ultraviolet rays to weaken any viruses that might be present. Dr. Bjorklund and a team of 14 other researchers, including his wife, have been working with it, largely supported by research money from the U.S. Government. Two years ago, Dr. Bjorklund was on the verge of deserting his work at Sweden's State Bacteriological Laboratories when the U.S. Public Health Service came to his rescue with a three-year grant...
Disappearing Trigger. Cancerous mutations, which are hereditary within cell lines, can be produced by X rays, ultraviolet light, some chemicals, and viruses. Different as these factors seem, said Dr. Horsfall, they are probably identical in that they operate only to produce the first mutation. After that, the cells go on multiplying abnormally, true to their mutant genes, even though the agent that caused the mutation is no longer present. This would explain why viruses that may have triggered human cancers cannot be found after the disease appears...
Sure that his colleagues would still suspect that ordinary modern bacteria had worked their way into his broth, Dombrowski developed elaborate precautions to keep the invaders out (including germ-killing ultraviolet light, antiseptic solution, and gas flames), repeated a laborious process 180 times. In 86 cases the broth contained a culture of living bacteria which, Dombrowski is sure, could only have come from the ancient salt. Most of the bacteria were strains of Pseudomonas, whose nearest modern relatives live in the intensely salt water of the Dead...
...ultraviolet infiltrating the atmosphere produces simple organic molecules. At the same time, the sun's rays penetrate to the planet's surface, inducing infra-red radiation. The cloud cover traps this heat, forming the oceans of water or ammonia into which the falling molecules (formed at the impressive rate of ten pounds per square mile per year) dissolve. This process, says Sagan, "would create the conditions necessary for complex pre-biological organic reactions." By his reckoning, Jupiter's rind may not be icy at all, and its surface temperature (70° F.) may be balmy enough...
