...Electron Microscopes now attract much attention among scientists who want to see ever smaller & smaller things. The magnification of ordinary microscopes is limited by the wave nature of light. Some things are so small that they slip through the meshes of the light rays like BB shot through a tennis net. Instead of a beam of light the electron microscope utilizes a beam of electrons, which have wave lengths thousands of times shorter than visible light but also make impressions on photographic plates...

Meanwhile Walther Heitler, co-author of a famed theory of electron absorption in gases, had called into theoretical being still another particle, the neutretto-similar in mass to the barytron but having no electrical charge. The existence of neutrettos has not been proved. But in Chicago last week Physicist Francis R. Shonka of the University of Chicago reported high-altitude cosmic-ray experiments, in which he juggled various arrangements of Geiger-Muller cosmic-ray counters and selective lead shields, obtained evidence of something which he took to be electrically neutral particles of high penetrating power...
