Naming a thoroughbred race horse is a delicate and demanding task. Rules of the Jockey Club-racing's all-purpose arbiter-require that the monicker contain no more than 18 letters, and that it not duplicate one of the 150,000 names now in use, or, for that matter, one used at any time during the past 15 years. With few exceptions, it cannot be the name of a commercial product or of an illustrious (or notorious) person living or dead. It cannot be a copyrighted name-say of a book, play, movie, song or magazine. It cannot...
...that softens the glue holding the silk threads together. Kafatos discovered that a certain drug made the liquid appear on the moths' face, even when they were not trying to escape from a cocoon, and collected the liquid efficiently by applying the drug. After realizing that the liquid must contain some material in addition to salt and water, Kafatos guessed that an enzyme, a chemical agent that helps break down or "digest" other chemicals, was the liquid's active element...
Kafatos' first step in testing the reality of informosomes was to get an idea of the composition of his messenger-carrying particles in silk worms. Ribosomes are about 50 per cent protein and informosomes, which may be similar to ribosomes, have been postulated by the Russians to contain a higher amount of protein. Chemical analysis of the particles suspected to be informosomes was impossible because Kafatos was dealing with such minute amounts of particles. Finally he turned to a method for testing a particle's density devised ten years ago by Harvard's Matthew Meselson, professor of Biology. Particles...
...Fully 40% of all offspring on the national rolls of the Aid for Dependent Children program are illegitimate. AFDC spent $2.3 billion last year, up from a quarter of a billion dollars 20 years ago. One angry black Atlantan estimates that 616 poor Negro households in her housing project contain only 30 headed by a husband. The rest are women-dominated. Mrs. Marie Childress of Cleveland, for example, receives only $102 a month to feed and clothe ten children. Many AFDC mothers conceal pregnancies as long as possible, and by not seeing doctors, often end up with birth difficulties...
Study in man is vastly complicated by the fact that the human brain contains an estimated 10 billion nerve cells called neurons, and another 100 billion of a second type called glial cells. The fluid bath in which they are suspended is an important element in their electrochemical interactions. Moreover, said Sweden's Dr. Holger Hydén, one big neuron may have on its surface as many as 10,000 points of contact (synaptic knobs) with other neurons (see chart). But by means of exquisitely delicate instrumentation and an electron microscope, Dr. Hydén has discovered that...
