Having dispatched with the nucleic acids, showing how they could originate and function by random events. Monod moves to the question of cellular proteins. The processes of life within a cell--metabolism--are carried out primarily by proteins: enzymatic proteins, regulatory proteins, structural proteins. Monod carefully constructs for the reader the essence of enzyme functions and mechanisms as they are presently known and builds from this a model for complex, intricate interactions (as they must be inside the cell) which originated and shaped themselves by chance...
...pace of the experiments picked up last spring when a solution made from the malignant cells was injected into unborn kittens. Four of the animals, all from different mothers, developed tumors. In effect, the cancers created were almost entirely of human cellular composition. One of the tumors was shedding C-type virus particles, similar to those known to cause cancer in animals, at a prodigious rate...
...that carries genetic instructions from one part of the cell to another) so they could later identify it. Then they mixed these radioactive strands with complementary strands of genetic material from viruses carrying the crucial gene, hoping that they would combine; pairing off would take place only if the cellular RNA now had the same genetic structure...
Died. Dr. Paul Niehans, 88, the Swiss surgeon who won both reputation and fortune by trying to lead his celebrity patients to the fountain of youth; in Montreux, Switzerland. In 1931 Niehans developed his so-called "cellular therapy," in which particles of lamb embryos were injected into the patient; he claimed that the treatment would retard the aging process, and cure almost everything from homosexuality to heart disease. Though viewed with suspicion by many fellow doctors, Niehans counted among his grateful patients Pope Pius XII and Gloria Swanson...
...developed their symptoms following influenza-like illnesses. Others began to suffer from the disability after undergoing surgery unrelated to the nose, mouth or throat. None had readily observable abnormalities of the sensory organs. But Dr. Robert Henkin reported that when taste buds were examined with an electron microscope, marked cellular anomalies were noted...
