...they have produced, man would long since have vanished from the earth." Watching the stars, he brings the trained mind of the evolutionist to bear on the possibility of the existence of life on other planets, but explains his conclusion with his own special brand of eloquence: "Life, even cellular life, may exist out yonder in the dark. But high or low in nature, it will not wear the shape of man. That shape is the evolutionary product of a strange, long wandering through the attics of the forest roof, and so great are the chances of failure, that nothing...
...devotes special attention to endoplasmic reticulum, the cellular structure involved in the synthesis of proteins which the cell transports. "The endoplasmic reticula of normal, differentiated cells," Porter said, "appear in patterns, which may be reflected in the forms of the cells. But in very malignant cells there is no pattern...
...surgery begins, the cellular engine may have already shrunk from starvation (for example, that caused by cancer of the gullet or stomach), from infection, or from the storage of excess water, as in the edema that goes with congestive heart failure. The faltering engine gradually loses its power to deliver blood-borne nutrients to the muscles. Then the most vulnerable points, said Dr. Moore, are in the diaphragm and the muscles between the ribs. And the effects are most severe on breathing and coughing. The cause of death in surgical patients, he said, is seldom found in the heart, brain...
...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 has in its nucleus a set of instructions, organize themselves independently of any cellular high command...
After 18 months' preliminary study, the Colorado group decided to work on three central ideas, divided into the "blue, yellow and green courses." The blue, or physiological approach to biology, will emphasize the underlying cellular activity in all living matter; the yellow, or morphological approach, will compare the structures of organic types; while the green, or ecological approach, will trace the evolution of forms and how they relate to one another. Specific species and experiments will fit into the overall pattern, not dominate the course...
