...fertilized egg, and implanting it in a scrub cow, which merely acts as a live incubator. The calf that is born is a prize animal with none of its mother's bad blood line. Scientists see a time when a farmer will buy a packet of fertilized ova, and in one year obtain from his scrub cows a herd of the finest cattle. To obtain the eggs in sufficient numbers, the donor cows would be fed hormones to make them super-ovulate. Formidable cost problems must be faced before the experimental process is commercially possible. Another big obstacle...
...virgin births possible in nature? In guppies, yes, because the female may be a hermaphrodite and, by producing sperm as well as ova, fertilize herself. In rabbits, fatherless reproduction has been observed after the doe's ovaries are chilled. But in humans? Maybe, says the Lancet of London, and last week doctors went to work to see whether there are living proofs in England today...
...three scientists - R. L. W. Averill, C. E. Adams and L. E. A. Rowson -flushed out newly fertilized ova from the Fallopian tubes of freshly killed pregnant ewes. Then they transplanted the tiny ova to the reproductive tracts of seven female rabbits which had been mated previously with sterilized males to activate their hormone systems. Five days later, the rabbits were killed and the sheep eggs taken out in surgery. The ova had grown as in any pregnancy. Two of the best-developed eggs were replanted in a nonpregnant ewe; 16 days later, the scientists found that the twice-switched...
...future experiments, Averill & Co. hope to determine the survival rate of sheep ova in their early development, devise a technique for shipping eggs from the best breeds of sheep in "incubator" rabbits round the world to help sheep growers build new and better flocks...
...jobs are opening up for handicapped workers. What the handicapped lose in flexibility because of their disability, they make up by concentrating on a single job, or a few jobs, learning to do them better. Firestone has 150 deaf employees alone. Allis-Chalmers, IBM, Hughes Tool, Procter & Gamble, Bui-ova Watch Co., Eli Lilly (drugs) have all found use for handicapped workers; electronic firms such as RCA, Western Electric, General Electric are using them to assemble delicate TV and radar circuits. At Lockheed's big plant at Marietta, Ga., the company last year saved $65,000 by employing...
