...phenomenal new electron microscope (TIME, Dec. 14, 1942) has been taking a good long look at hitherto invisible objects. In the last two issues of the Journal of the American Medical Association, its bacteriological discoveries have been summarized. (Most of the 60 machines in existence are used in industrial work.) The microscope's great magnifications-50,000 to 130,000 times normal size-have proved the existence of some things (e.g., molecules) only imagined before, of other things never imagined.* Some findings...
...Journal's summary concludes that the electron microscope can eventually help doctors figure out a drug or vaccine to cure any infection...
There is another reason for this X-ray tube's phenomenal performance: it uses a "magnetic lens," similar to that in the electron microscope (TIME, Dec. 14, 1942), to focus the electron beam in the tube on a bull's-eye only .01 inch in diameter, instead of the usual quarter-inch focal spot. Thus the X rays emerge in a sharp beam and produce well-defined shadows even after passage through thick steel...
...Says he: there is a strep-polio axis-somehow, in ways no doctor understands, streptococcus plays a malignant part in infantile paralysis. (A coccus is a round bacterium large enough to be seen with an ordinary microscope. A virus is so small it can be seen only with an electron microscope, has some bacteria-like and some protein-like qualities-no one knows for sure whether it is living matter or a chemical...
...current. His results suited another youngster, 27-year-old James T. Kendall of England's Metropolitan-Vickers laboratory. Dr. Kendall declared in Nature that Ehrenhaft's claims "may turn out to be no more valid than his previous claims of the existence of charges smaller than the electron...
