Kent's heart stopped soon after the heart sac was cut open, but promptly picked up its beat again on being massaged. Dr. Glenn cut through the right pulmonary artery (see diagram) at its beginning near the ventricle, carried the free end around to a hole, half an inch across, cut in the side of the superior vena cava, and stitched it in, like a plumber's elbow joint. Then he tied off the vein near its normal entrance to the auricle. In this way, 30% to 40% of Kent's venous blood (the proportion carried...
...rocket engine depends largely on its exhaust velocity, the nuclear engine has a big initial advantage, but it has to pay a high price. The engine itself, which must be cooled elaborately by the liquid hydrogen, will be about as complicated as a conventional chemical engine (see diagram). Its controls will be even more complicated, and all its delicate parts will have to perform perfectly in spite of intense gamma rays striking through them at takeoff...
...years, the U.S. has multiplied its total outlays for medical research by a factor of four (see diagram). The sum will reach at least $400 million in 1958, including $220 million in congressional appropriations. $130 million spent by industry, $50 million by foundations, voluntary health associations, universities and their medical schools. Is this enough? For the present, yes was the consensus of the experts quizzed by Bayne-Jones's group. Or as Dr. James A. Shannon, director of the National Institutes of Health (which handles 70% of the Government's outlays in this field), last year told Congress...
...nuclei of cells. When a cell divides nonsexually, as in a growing plant or animal tissue, the chromosomes replicate (make copies of) themselves. Each daughter cell gets a full set, and unless something has gone wrong, it is exactly like the chromosome set of the parent cell (see diagram...
...horizontal members, like steps, connecting the two spirals. This molecular model, deduced mostly from X-ray diffraction photos, seemed complex and unlikely, but geneticists rejoiced when they heard about it. It was just what they" needed to explain many perplexing things that they had been observing for years (see diagram...
