...question time, the long-haired youths in jeans and sneakers fired away: Is the fission theory of the moon's origin the most powerful one? Is there life on other planets? ("I don't believe in UFOs," said Dr. Adler, "but I'd be astounded if there was not life in some other solar system...
...would be no easy task. Two different species of bacteria would first have to be induced to conjugate. This is a primitive form of sexual reproduction in which two bacterial cells occasionally meet and exchange genetic material prior to their more common asexual form of reproduction, called fission (in which a single cell elongates, splits and produces two genetically identical offspring...
...most bacteria, it can incorporate genetic material from another species. Out of the laboratory-induced union came a small but significant number of hybrid offspring with nitrogen-fixing ability. What is more, some of these crossbreeds could pass on the crucial nitrogen-fixing genes to future generations through ordinary fission...
Like ordinary nuclear reactors, breeders produce heat through fission-the familiar process of splitting unstable radioactive atoms by bombarding them with small, fast-moving particles called neutrons. As the atoms disintegrate, they release large amounts of heat that can be converted into steam and used to drive conventional turbogenerators. They also release additional neutrons, which in turn smash neighboring atoms and thus continue the heat-producing chain reaction inside the reactor...
...reasons are obvious to medical researchers. Scientists understood the principles of nuclear fission long before they undertook to build an atomic bomb, and grasped the physical principles of spaceflight before they attempted to send a rocket to the moon. They have no such unified store of fundamental knowledge about cancer. Says Columbia University Researcher Sol Spiegelman: "An effort to cure cancer at this time might be like trying to land a man on the moon without knowing Newton's laws of motion." A better-funded research effort could help science to understand more about the many diseases that...
