...actions outraged experimenters. Some doctors said the charges against their four colleagues amounted to a count of illegal abortion for a method of research they argued was standard. Scientists reported that the indictments successfully dissuaded further fetal experimentation at the time...
...natural element uranium contains only .7% of the isotope U-235. It must be enriched to 90% for use in nuclear warheads, a vastly expensive and complex process. A typical plant using a gaseous diffusion method covers about 90 acres, uses about 400 million gallons of recirculating cooling water per day, requires 1,300 megawatts of continuous electrical power (enough to meet the needs of a city of about 600,000) and costs about $2 billion to build. Only the U.S., the Soviet Union, Britain, France and China have such gargantuan processing plants; they thus have been able to exercise...
...rats by dioxin concentrations of less than one part per billion-lethal levels so minute that researchers have trouble measuring them. Because of this experimental difficulty, the EPA says it still lacks sufficient evidence to press for a ban on 2,4,5-T. But, using a newly developed method of analysis, the agency plans to continue its investigation...
...additional risk of accident involved in the new generation of gas-cooled reactors or the next generation of fast-breeder reactors. In addition, anti-nuclear critics like the Union of Concerned Scientists in Cambridge, Mass., vow to scrutinize WASH-1400 for any oversimplification, any error in calculation or method that might discredit the work...
...quietly installed Mr. Ford. This is a revolution. In most countries of the globe it would be a violent revolution, but in the U.S. it is peaceful and legal.
