...test of this effect, expanded from the hypothetical elevator into a global picture by his field equations, that finally brought Einstein worldwide attention. General relativity indicated that when light from a distant star passes very close to the sun on its way to earth, it should be deflected by solar gravity, thereby shifting the star's position in the sky. The amount of shift, Einstein calculated, should be 1.75 seconds of arc?a small variation, but one discernible by astronomers of the day. But how could astronomers photograph a star nearly in line with the sun when it would certainly...
...hospital. Almost as soon as the patient slips into a hospital gown, he or she faces the standard diagnostic assault. Aptly known in medical jargon as the admission battery, it includes such procedures as a chest X ray, electrocardiogram, blood-cell count, blood-chemistry analysis, venere al-disease test and urinalysis...
More on the test-tube birth...
After the birth of the world's first test-tube baby in Britain last July 25, little Louise Brown's scientific godfathers, Gynecologist Patrick Steptoe and Physiologist Robert Edwards, were sharply criticized by some American colleagues for failing to reveal all the details of their pioneering work. Last week Steptoe put the critics to rest. At a meeting in San Francisco of the American Fertility Society, the British researcher delivered an hour-long lecture on the birth of Baby Brown and other hitherto unpublicized facets of the British pair's research. The talk had a dramatic effect...
...premature births of the two living children and the loss of the other two babies are not related to the method of conception. He notes that the mothers were under tremendous stress and that the chromosomal imbalance occurs in naturally conceived pregnancies as well. Hence, while he acknowledges that test-tube fertilization needs further refining, he says that "the method is no longer experimental. It is ready for clinical application...
