...supremacy by writing a "union shop" into a new agreement. This would guarantee that for the next two years only Lewis miners could get jobs in most coal mines. The operators refused. Miner Lewis then asked them to waive a clause in the old contract, which in effect forbade his men to strike, thus freeing him to fight A. F. of L. encroachment by making it costly for the employers. The operators refused. He then offered to keep his men at work under a temporary extension of their old agreement, pending further talk about his demands. The operators refused, insisted...
...balance of power. But what the Foreign Ministers had announced by implication was that Italy would automatically come to the help of Germany in case of trouble, and vice versa. With the fate of the Free City of Danzig already at issue between Germany and Poland, the announcement in effect placed Italy's full force behind Germany's demands...
...injections, brandished a hypodermic needle. When no one volunteered to give him an injection of the acid, he gave himself a standard dose, thus convinced his timid colleagues that the acid was harmless. What he was unable to say, however, was why pure oxalic acid produced the opposite effect of the derivative form...
...cancer cells, but no scientist had ever worked out a satisfactory theory for this phenomenon. Two years ago Italian-born Physicist Gioacchino Failla, who is in charge of the physics and biophysics laboratories at Manhattan's famed Memorial Hospital, suggested a straight-forward physical theory for the lethal effect of X-rays. An electric charge passing through a cell, said Dr. Failla, divides the molecules of protoplasm into positively and negatively charged particles. These ions then recombine to form new chemical substances. In a vain attempt to re-establish osmotic equilibrium in the cell, water from the intercellular spaces...
...mice infected with a deadly form of mouse cancer known as sarcoma 180. Then they injected into the tumors small amounts of sterile, distilled water several times a day for three to six days. Results: small doses of X-rays, when followed by water, produced an unusually strong effect. Large doses of over 1,000 Roentgen units, when followed by water, completely destroyed all the mouse tumors. When the scientists omitted the X-rays, tried only water, the cancer cells did not die-only the combination worked...
