Ordinary x-ray pictures, taken after the patient has eaten a paste of barium sulphate, show only the outline of the stomach. A method of outlining all the rugae occurred to a few roentgenologists. notably to Dr. Aubrey Otis Hampton, 34, a sharp-nosed Texan who went to Boston to practice medicine. Last week he explained the method to other fellows of the American College of Surgeons (see p. 35) who crowded his lecture in Boston...
...been reproduced and extended in dozens of laboratories in a half-dozen countries, notably England, Italy, the U. S. Italy's Professor Enrico Fermi and his aids have coaxed radiations of beta particles (fast electrons) from phosphorus, iron, silicon, aluminum, chlorine, vanadium, copper, arsenic, silver, tellurium, iodine, chromium, barium, fluorine, sodium, magnesium, titanium, zirconium, zinc, strontium, antimony, selenium, bromine...
Most assiduous imitator of the Curie-Joliots is Professor Enrico Fermi, 32, Italian physicist. Using neutrons instead of alpha particles or deutons, he has produced radioactive forms of two dozen elements from fluorine to barium...
...automobile in which he pursues rats throughout the U. S., bringing with him two large suitcases and his young wife. Ratkiller Nicholes went to work. Wherever rats were plentiful he distributed pieces of bread, hamburger steak and apples, in each piece of food a drop of his chemical (barium carbonate with a slight touch of barium sulphide). Because the Nicholes poison is comparatively slow acting the rats do not die on the premises they infest. Hungry human beings who might eat the poisoned food, which is odorless would not be harmed. They would vomit immediately. Rats cannot vomit...
...noteworthy that neutrons have been recognized as coming from elements which are the lightest of their groups in the Periodic System. Beryllium is the lightest of the earth alkali group (beryllium, magnesium, calcium, strontium, barium, radium). Boron is lightest of the earth metals (boron, aluminum, scandium, yttrium, lanthanum, actinium). Fluorine is lightest of the halogens (fluorine, chlorine, bromine, iodine and, newly recognized, alabamine...
