...pair of treelike bony structures located above each gill cavity, the organs absorb oxygen from the air to supplement the oxygen normally taken in from water passing through the gills...
...Death," Hudson said, "is a gradual process at the cellular level, with tissues varying in their ability to withstand deprivation of oxygen. Medical interest, however, lies not in the preservation of isolated cells but in the fate of a person. Here the point of death is not so important as the certainty that the process has become irreversible...
...After the incisions were made, the real technical difficulties began. Moore and his chief assistant, Dr. Alan Birtch, clamped off the portal vein, which delivers blood to the liver for chemical processing, and the inferior vena cava. The hepatic artery, which delivers blood for the liver's own oxygen needs, was so damaged by pressure from the cancer as to be useless. Moore and Birtch decided to use in its place the right kidney artery. That meant removing the right kidney, but a single healthy kidney is all the body needs...
...P.H.S. did not limit its concern to lung cancer, but pointed to an "increasing convergence" of new evidence that smoking can contribute to the development of heart disease. It does this, according to latest research, by producing a gap between the heart's demand for oxygen and the blood's ability to supply...
Three planets were nominated as possible havens for such life. Nobel Chemistry Laureate Willard F. Libby speculated that oxygen detected on Venus by a Soviet space probe last October may well be the product of plant photosynthesis. Jupiter, said NASA Chemist Cyril Ponnamperuma, has an atmosphere similar to that which enveloped the earth during its first 100 million years; the swirling Jovian gases, he added, may already have combined into basic life-building molecules. But the strongest argument was made on behalf of Mars. Despite its freezing temperatures and apparent lack of oxygen, explained NASA Microbiologist Harold P. Klein, life...
