Rogge's book is filled with such examples of indiscriminate and ignorant persecution of the minds and earning capacities of American men and women...
Like every other chemistry department, Harvard's test-tube scientists spend a lot of time trying to stamp out cancer...
...ending of this condition. Our primary interest is in the development of a systematic and rigorous body of social theory capable of predicting behavior. To state that we are getting more empirical is only to state that we are interested in the operation and materials by which we can test our theories...
...test now looks simple, but Dr. Richardson, 52, has been working for five years to develop it. It is based on the long-known fact that the amount of the female hormone, estrone, in the urine increases greatly after conception. First, Dr. Richardson puts a specimen of urine in a special double-barreled test tube he invented. Then he gets rid of other hormones (progesterone derivatives), which might interfere with the test, by mixing in chloroform and sodium hydroxide. The fluid containing estrone rises to the top. This fluid is put in two other test tubes and a different chemical...
...Richardson has tried his test 1,000 times. At first, before he perfected the technique, there were a few "false positive" errors. In a later series of 467 tests (235 pregnant, 232 not), there were no errors. Any competent pathologist, he says, can make the test as soon as he has the two reagents handy. Dr. Richardson will not tell what they are until he publishes his report in a medical magazine. His reason: he does not want some one pharmaceutical house stealing a march and rushing out with a kit to get rich quick on his quick test...
