...mainspring of life is photosynthesis, the process by which plants manufacture food out of carbon dioxide-and water under the influence of sunlight. So one of the problems of biology is to learn as much as possible about photosynthesis. If the process could be made more efficient, the world's food supply would take a large jump. Since photosynthesis depends on the energy of sunlight, it stops when a plant is in darkness. In fact it runs backward. A plant respires (breathes) like an animal, absorbing oxygen and giving off carbon dioxide, and biologists have assumed that the plant...
...French artist and an Arabian princess in the shadow of the Sphinx, and was possessed of such combustible Circe charms that her contract forbade her to ride public conveyances or go out without a veil. Her public ate it all up. She slithered her way through 40 carbon-copy roles in the next five years, upped her salary from $150 to $4,000 a week, retired in 1921 to marry Director Charles Brabin and live the quiet life of a well-fed, well-to-do suburban matron...
...carrying the blood toward the heart, inserted a tube, and led the blood out to the input tube of the dog's lung. Inside its cylinder the lung was kept supplied with fresh oxygen. As the boy's blood coursed through the lung tissue, it gave up carbon dioxide and picked up fresh oxygen. Then it fell to the bottom of the cylinder. From the pool that formed there, another tube led the blood to a pump which boosted it back to Patient Richmond's aorta-the great artery in his chest...
Since then, Hubbs has rummaged through many ancient heaps of kitchen midden and found many shells of creatures that do not live there any more. Some of them he sent to the University of Chicago to be analyzed in two ways: for carbon 14 to tell their age, and for oxygen 18 to tell the temperature of the water in which they were formed...
...whole, Dr. Kuiper concluded, the meteorology of waterless Venus must be rather simple. There are no ocean basins to complicate the circulation of the dusty carbon-dioxide winds. The yellow dust merely drifts along; it does not condense unpredictably and fall as capricious rain to confound meteorologists...
