...molten interior (the maria melting could have been caused by meteor impacts), scientists would be hard put to sustain one of the theories of the moon's creation: that it was torn, cataclysmically, from a hot earth. On the other hand, a cold moon does not upset either of the two other major moon-origin theories: that it was formed from scattered cosmic debris whirling around the earth, or that it was a planetary interloper captured when it strayed into the earth's gravitational field...
...Manhattan, the city's Landmarks Preservation Commission unanimously vetoed the Penn Central Company's second bid to build a $100 million office tower above Grand Central Terminal. To build it the company would either have to destroy Grand Central's facade (a superlative example of the ornate Beaux Arts style and a splendid climax to the long sweep of lower Park Avenue) or crowd it with a bland, impersonal slab set only 30 feet behind it. Either plan, the commission ruled, was unacceptable in a city already too poor in dramatic vistas. The commission's decision...
Researchers will go anywhere and test anything in the hope of finding medicines to use against diseases and disorders that by present methods are either difficult to treat or incurable. One of their most fortuitous finds was made in a Peoria (Ill.) market, where they scraped from an overripe cantaloupe the parent strain of mold that fathered millions of doses of penicillin. Now that most of the world's land surface has been finecombed for microbes that might yield new antibiotics, the scientists are turning to the sea. One useful drug, cephalothin (which is effective against many germs that...
...substance. Once that is done, it must be tested in animals to find out whether its germ-killing powers outweigh whatever undesirable side effects it may have. If the compound proves both safe and effective enough to be tested in man, the laboratory chemists will face the task of either synthesizing it or using the natural product as the base for a semisynthetic drug, the technique that is used in producing cephalothin...
Shaw was never a comfortable man to have around, and not merely because he was a teetotaler and a lifelong vegetarian either. As a house guest he would immediately set about rearranging the furniture and taking over the education of the children. His passion for showing people how to do things extended to his biographers ("The best authority on Shaw is Shaw," he told Archibald Henderson), and he insisted on writing a good part of his biographies by Henderson, Hesketh Pearson and Frank Harris. He simply could not bear to see anyone doing something he could do better...
