...PLASMA PHYSICS : Has nothing to do with blood plasma, concerns the electrically charged gases that physicists call plasmas...
Joseph Portnoy described a new and simplified test which its developers claim is truly portable and fast. Called the RPR (for Rapid Plasma Reagin) card test, it requires only three drops of blood, obtained by pricking the subject's finger...
...blood does not have to be centrifuged or heated. After the red cells settle out, the plasma is transferred to a dimpled card, reagents are added, and the result of the test can be read with the naked eye instead of a microscope. The process takes only five to eight minutes...
...most purposes there are handier ways to communicate, but Dr. Tomiyasu has his eye on a notoriously difficult communication problem. When a missile nose cone or a spaceship slams down through the atmosphere, it surrounds itself with a sheath of plasma (hot, ionized gases) that repels radio waves. Space scientists well remember that during the most critical period of Colonel John Glenn's return to earth from his orbital flight, the radios of his Mercury capsule were blacked out for seven minutes by the plasma sheath. Laser light, if strong enough, can penetrate plasma, and Dr. Tomiyasu believes that...
...estimated 10% of U.S. transfusion blood is drained from paid donors by commercial supply houses, which sell the blood for profit. They need a license from the National Institutes of Health for interstate shipments. They flourish in the Midwest and the South. One such is the Community Blood and Plasma Service Inc. of Birmingham, Ala., which sold blood to the indicted Westchester dealers, but, far from being implicated, helped Public Health Service officers open up the case. It pays donors an average of $9 but may go to $20 for rare types. In segregated Alabama, its blood is labeled...
