...their promise, many design problems must be solved before breeders can produce electricity on a commercial scale. One difficulty lies in handling the coolant-the liquid or gas used to transfer heat from inside the reactor's core to a steam-producing boiler outside. Unlike conventional reactors, which use water as a coolant, the so-called liquid-metal "fast breeders" planned by the AEC will use liquid sodium, which is an extremely efficient thermal conductor. But since sodium also burns in air and reacts strongly with water, it requires elaborate safeguards to prevent a mishap that could leak radioactive...
...first round arouses suspicion, a second test, also based on Murayama's work, is performed immediately. Urea, a natural waste substance produced by the normal liver, breaks some molecular bonds in abnormal hemoglobin. When urea is added to the solution that had shown a positive reaction initially, the liquid clears quickly if hemoglobin S is present...
...program owes its origin to several recent scientific discoveries in the field of molecular biology. One was the identification of the enzyme hexosaminidase-A, the lack of which causes Tay-Sachs disease. Another was the development of a technique for taking cells from the amniotic fluid, the clear, amber liquid in which the developing fetus floats, and analyzing the cells for the presence-or absence-of the essential enzyme. The most important step, however, was perfecting a simple blood test to identify adults who carry the defective gene but are themselves unaffected...
Expensive Thermos. Natural gas is cheaper (about 3? less a gallon) than regular gasoline, but converting an automobile to use liquid natural gas is an expensive operation: $625 to $750 per car. The major cost is for the tank that holds the gas, a complicated thermos-type bottle into which the liquid gas is poured at-259°F. A tank pressure of 70 lbs. per square inch forces the liquid into a combination pressure regulator and heat exchanger. The heated gas is then mixed with air in the carburetor and flows into the cylinders, where it burns more completely...
Police Badge. Hollywood boasts a shop, the Liquid Butterfly, that specializes in the custom patching of jeans. Owner Charlotte Stewart says she is "trying to get people to recycle their clothes. Instead of throwing out a ripped pair of jeans, we think it's nicer to put a pretty patch on them." One of her recent productions is a pair of jeans embroidered to resemble a hollow tree, with 13 butterflies, a bee and a ladybug buzzing up from it. That assignment took about 30 hours and cost the owner $65. The buyer, she notes...
