...pictures were taken with an electron microscope developed by R.C.A. (TIME, Oct. 28). The photographic plates were exposed by beams of electrons instead of beams of light. Practical limit of light magnification is about 2,000 diameters, of electron beams 100,000. These molecules are about ten-millionths of an inch long. In the picture above they are shown alone; in the picture below, they look fuzzy and out of focus because they are clustered over with antibodies, smaller molecules which produce immunity in organisms by reacting with the larger virulent ones. It is an action shot of a battle...
...tobacco plants, one of the largest molecules known to chemists. It is a rod-shaped structure, about 40,000,000 times the size of the hydrogen atom (basic unit of atomic and molecular weight). But even at this size it could be photographed only with the recently developed electron microscope (TIME, Oct. 28), which by using electron beams instead of light can magnify images 50 times greater than the best light microscopes...
...laboratories in Camden announced a new, simpler electron microscope for educational and research laboratories. Like earlier and bigger models, the new instrument uses beams of electrons instead of beams of light for magnification, furnishes enlargements up to 100,000 diameters, but it can be plugged into an ordinary electric outlet...
...they still insist it is far off. When a slow-moving neutron hits the uranium atom's nucleus, the nucleus is constricted around the middle and finally splits, like an amoeba reproducing itself. But though the energy of the activating neutron is only a small fraction of one electron-volt, 200,000,000 electron-volts of energy are released. Last fortnight, Dr. Richard David Present of Purdue described a three-way split. If conditions, including the energy of the entering neutron, are right, two constrictions instead of one crease the atom, dividing it into nearly equal thirds. First...
When a film is developed, silver atoms clump together in tiny islands. It used to be assumed that these clumps were a grainy, cokelike mass. It was just an assumption, because no ordinary microscope could penetrate the clumps. In the Eastman laboratories, Researcher C. E. Hall made electron pictures magnifying the silver islands 25,000 times. Then it was seen that they were composed of tangled, thin strands of silver, some of them only a few atoms thick. "The developed grains," said Dr. Mees. "resemble masses of seaweed rather than coke...
