...mounting knowledge, oceanographers are talking with new confidence of the ocean as a source of food. Life began in the sea, and most of it lives there still, grazing on the microscopic plants that swarm in the sunlit upper waters. At the end of a long food-chain (diatoms, protozoa, tiny crustaceans, little fish, etc.) are the fish, lobsters, shrimps and whales that are hunted by humans. Says Iselin: "We are not harvesting the seas. We are just hunting-catching something here and there...
...silver, oil, fat, starch or mammalian cells on a glass slide between the electrodes, he found that any asymmetrical particle promptly turned so that its long axis lay along the lines of force. Groups lined up Indian-file, like iron scraps between magnetic poles. Microorganisms such as bacteria or protozoa were forced to travel in similar paths; they resumed swimming normally at random only when the power was turned...
...walls of nature's cells are permeable to specific chemicals and to electric currents. The Cash men see no reason why their synthetic cells (which are about the same size) should not be trained to behave in this way too. They are not trying to synthesize bacteria or protozoa, but there is at least a possibility that Cash's capsules can be made to resemble the neurons (nerve cells) of the human brain and to take over some of their functions...
...just divided into two new individuals. Working with a powerful microscope, he picks one of them up with a hairlike suction tube and delicately transfers it to a minute cup on top of the Cartesian diver. It cannot escape, but it thrives slimily on a broth of smaller protozoa. By measuring the pressure that will keep the underwater Cartesian diver on the zero line, Dr. Prescott can weigh his captive amoeba at all stages of growth. When the amoeba has doubled in weight, it generally divides into two "daughters...
...Mike. Hit of last week's industrial fair at Hannover, Germany, was a three-dimensional projection microscope designed by Dr. Friedrich Fehse of Hamburg. It projected repulsive little creatures (protozoa, bacilli, etc.) on a three-foot screen and enlarged them to the size of rabbits. Observers wearing polarized glasses got the shock of their lives. The blown-up varmints appeared to be swimming toward them, even reaching for them...
