Life among higher animals starts with a single fertilized cell. In a few days or weeks, it divides into billions or trillions of cells of different kinds, all arranged to help each other in the difficult business of life. How does this miracle happen? Scientists agree that the original cell contains genetic instructions that control the development of the embryo, but they are not sure how these instructions are brought to bear. One theory is that some central part of the embryo issues orders that make each tissue and organ develop. Another is that the multiplying cells, each of which...
...with the advisable speed of things outside the law and people on the lam-or it kicks its heels with Parisian verve and pertness. Marguerite Monnot's score has a gay street-music tinniness that can have resonance too, as in the rousing wail of From a Prison Cell or the ring and bounce of There Is Only One Paris for That. But it is England's dark, dynamic Elizabeth Seal in the title role-indeed, as the only woman in the show-who stands foremost. Without her fresh, bright gifts for dancing and prancing and singing...
...fight for women's suffrage between 1903 and 1918, led her militant followers in rock-tossing sorties against the Houses of Parliament, assaults upon 10 Downing Street. She landed in prison at least 15 times, went on hunger strikes to get out, promptly got tossed back into a cell as soon as her strength returned. After Britain's women began to win the vote in 1918, Sylvia was not long without other causes. She flirted with the triumphant Russian Bolsheviks, fought fascism, ground out radical books and pamphlets, even ran a cooperative toy factory. Ever a champion...
Another remarkable thing about living organisms is their ability to store in the nucleus of a single microscopic cell all the genetic information that makes that cell develop into a vastly complicated creature such as a fish, a bird or a man. Dr. Savely does not expect that those deep mysteries will be solved soon, but he is sure that study of them by physicists, chemists and mathematicians, as well as by biologists, will add enormously to the power of scientific...
Trauma can aggravate an already existing growth by disrupting its capsule, said Dr. Auster. An injury in the area of a tumor may cause an increase in the growth's size-by hemorrhage, cell destruction or infection. But for the patient who had a tumor and didn't know it, this might be helpful, not harmful. In other cases, physical trauma in the tumor area, said Dr. Auster, may even have a distinct beneficial effect: by destroying the cells, it may cause the tumor itself to heal...
