Research Leads. Traditionally, the brain has been supposed to require a superabundant blood supply, but the difficulty has been to determine how much. Stockholm's Dr. Gustav Nylin reported that he had injected red blood cells labeled with radioactive thorium into healthy test subjects, discovered that the major blood flow through the brain is normally much less than previously believed-and notably less than in other body tissues. A series of blood-flow readings may help in the evaluation of treatment...
Buckling under the pressure of Nationalist army leaders, Brazil's President Juscelino Kubitschek last week halted thorium exports to the U.S., canceled the 1955 U.S.-Brazilian agreement to cooperate in exploring Brazil for deposits of radioactive minerals. The U.S. embassy in Rio first learned of the turnabout by reading about it in the local newspapers. Brazil's troublemaking Communists, who could never have brought off such a coup by themselves, whooped with delight. Bannered the Communist daily, Imprensa Popular: HISTORICAL VICTORY
...nationalists unite in taking a fiercely protective attitude toward Brazil's mineral resources ("The oil is ours!"). Months ago this alliance of extremes, which stunts the country's economic growth by barring foreign capital from oil exploitation, began denouncing exports of radioactive material to the U.S. (thorium oxide and thorium-bearing monazite sand, no uranium). The showdown came last week, when the Security Council, loaded with nationalistic armed forces brass, adopted a military-dominated commission's recommendations that Brazil suspend exports of radioactive minerals and end the joint-exploration treaty with the U.S. President Kubitschek meekly gave...
...Some authorities believe that a world population of 3 billion living at the "American level" would exhaust accessible deposits of fossil fuel in 23 years. Atomic energy, however, is inexhaustible. After all rich uranium ores are gone, the same granite that is processed for metals will supply uranium and thorium for atomic energy. Each ton of average granite contains as much energy as 50 tons of coal...
Reactors & Chemicals. The three producers are building plants with a capacity of about 1,500,000 Ibs. apiece per year, will thus have enough for both AEC and private needs. Aside from zirconium, other rare metals may come from AEC's program, e.g., thorium, currently under study as a cheap source for nuclear fuel...
