...Last week Lieut. General Alexander Archer Vandegrift of Guadalcanal and Bougainville packed up again. This time he was really on his way. Where that way would take him is still a Marine secret. His successor as commander of the South Pacific's Marines: Major General Roy S. Geiger...

...residents of West Milford, N.J. (plus some 10,000 summer visitors) will be without a doctor soon. Last week the town's only practicing physician, Dr. Harold C. Geiger, father of three, was called up by the Army Medical Corps. Dr. Norman Scott, secretary of the Newark office of the Army Procurement and Assignment Service, agreed with the worried townsfolk that the Army faced a "moral obligation" to replace the departing doctor or to arrange calls from doctors in other towns. But he warned: "West Milford is an example of what is going to happen in a great many...
...M.I.T. have announced that when a sample of rock is bombarded with neutrons (heavy nuclear particles) from the cyclotron, some elements in the ore become radioactive and give off particles which can be detected either 1) on a photographic film in contact with the ore, or 2) with a Geiger counter, an instrument which clicks or marks a tape as each particle shoots through it. Since each element has a unique rate of radioactive decay (e.g., radioactivity of manganese declines by one-half every 2.5 hours, of gold every 2.5 days), the identity and quantity of the hidden elements...
...detection of an element by its radioactivity is up to one million times as sensitive as by chemical analysis. The radioactivity can be detected by killing an animal after it has eaten radioelements, then assaying the radioactivity of its various tissues. It can also be detected by placing a Geiger counter, a device which measures radioactivity, over a part of the body where the tracer elements are suspected so that the metabolic ebb & flow of the tagged substance can thus be observed while the subject is alive. Or the detection can be accomplished by taking paper-thin slices of plant...
