Doctors now replace lost or damaged vitreous with either natural material taken from donors, saline solutions, air, silicone or other synthetics. None of those materials is completely satisfactory. The synthetics sometimes trigger toxic reactions that lead to further eye damage, the air is soon absorbed, and transplanted human vitreous may provide only short-term benefits. Now a research team at Cornell University Medical College's Rogosin Laboratories has developed a material that overcomes all these problems. According to Dr. Michael W. Dunn, he and his colleagues are using collagen, a natural body substance, to replace lost or damaged vitreous...
...annual debates in the General Assembly of the United Natiohs. These documents are enlightening for their records of verbal exorcism of apartheid by friend and foe alike. Consider, for instance, the session of Autumn 1963 in which the South African system was seen by the United States Government as 'toxic,' by the Soviet Union as 'shameful,' by England as 'abhorrent,' by Belgium as 'thoroughly repugnant,' by India as 'hateful,' by Guinea as 'inhuman,' by Bolivia as 'the negation of all social purpose,' by Japan as 'fundamentally immoral,' by Canada as 'degrading,' by Algeria as 'cancerous,' and by Tanzania...
...Canadian route would "serve mainly to shift the location of ecological problems rather than cure them." Both routes would disturb wildlife, and both confront permafrost. Hot oil, piped through this frozen ground, might melt the land around it, causing the pipe to sag and break-tarring huge areas with toxic crude...
...even camel dung, if there were enough camels," but he prefers kerosene. The fuel is not exploded inside the cylinder as it is in the internal-combustion engine but is burned in an external combustion chamber at atmospheric pressure. As a result it gives off much lower concentrations of toxic gases than present machines. Because there are no cylinder explosions, the steamer is fairly quiet, merely chattering and hissing instead of roaring like internal-combustion engines...
...fuel is stored in the reactor for a year at a time. Such materials may accumulate to 1000 times the radioactivity of one Hiroshima-sized bomb. Although a reactor cannot sustain a nuclear explosion, the presence of many hundreds of tons of material which is one billion times more toxic than any known industrial substance is an unparalleled hazard, especially during fuel replacement. Such replacement is an extraordinarily delicate operation and, in the case of Con Edison's Indian Point ?I plant at Buchanan, N. Y., took six weeks during which 40 of the 120 fuel elements were removed, each...
