...quietly as to be barely detectable, the U.S., over the past three or four months, has considerably modified its policy on willingness to try for a workable agreement with Russia on ending nuclear weapons tests. U.S. policymakers were solidly committed to one disarmament package: tests could not be stopped unless nuclear-weapons production was simultaneously stopped and conventional arms were cut down. But last week a U.S. scientific delegation sat down peaceably with a Russian scientific delegation in Geneva to discuss the feasibility of nuclear test inspection systems (see FOREIGN NEWS). Secretary of State John Foster Dulles had ringed...
Just before the scheduled start of "The Conference of Experts to Study the Possibility of Detecting Violations of a Possible Agreement on Suspension of Nuclear Tests," the Russians had threatened to boycott the talks unless the U.S. first agreed in advance to a ban on nuclear tests. The U.S. and its allies (Britain, France, Canada), rejecting this Soviet propaganda gambit, ordered their scientists to hold the conference among themselves if the Communist delegates (from Russia, Czechoslovakia, Poland, Rumania) failed to show up. This proved to be a shrewd move: the Communists arrived suddenly, and the conference began on schedule...
...connected Mendelian inheritance with the known behavior of chromosomes, which are threadlike bodies in the nuclei of cells. When a cell divides nonsexually, as in a growing plant or animal tissue, the chromosomes replicate (make copies of) themselves. Each daughter cell gets a full set, and unless something has gone wrong, it is exactly like the chromosome set of the parent cell (see diagram...
...York Central's President Alfred Edward Perlman warned that the line was ready to cut off all commuter service into Manhattan, close the famed Grand Central Terminal and terminate all routes 43 railroad miles away at Harmon, N.Y. unless the state and its cities "help" the line overcome its overall $1,000,000-per-week passenger loss. If the Central should move out, New York City would lose its third biggest (after Consolidated Edison and New York Telephone Co.) taxpayer ($16 million last year). To keep it, the city last week followed one Perlman suggestion, started a study...
...Massachusetts, the New Haven Railroad cheered for a bill to give a $900,000 subsidy to the line over the coming twelve months. Unless it passes, the New Haven may make good its longstanding threat to cut off passenger trains on the Old Colony Line, which would strand thousands of Boston's South Shore commuters...
