...whose currencies and balance of payments have borne the brunt of the increased world trade, the de-emphasis of gold and hard currency should bring some relief. The London agreement still awaits approval, however, by the 106 nations of the International Monetary Fund, which meets later this month in Rio de Janeiro. At that time, the plan will be spelled out in further detail. Remaining to be decided, for instance, is the amount of special drawing rights to be created. Best estimate is between $1 billion and $2 billion for a start. Though small in amount, the SDRs should, nevertheless...
...most ingenious new tool for riot control may be "instant banana peel," a powdery chemical introduced last week by Fort Worth's Western Co. of North America. Sprayed on the street and hosed with water, the chemical, which goes under the trade name "Rio-Trol," produces a surface ten times as slick as ice-and ten times as hard for rioters to walk on. Still in the early stage of experimentation by at least one company is a tranquilizer dart-a kind of instant Miltown-that could be fired from a distance, yet reduce any suspect to euphoric nonviolence...
...fulfill a longstanding six-week commitment to serve as senior scientist aboard the Alpha Helix, a sophisticated research vessel operated by California's Scripps Institution of Oceanography. From Manaus, Williams headed the Alpha Helix upstream for the expedition's shore camp at the confluence of the Rio Negro and the Rio Branco. The Negro, at high-water level during this time of year, "looked like Chesapeake Bay," says Williams. Along the shore, trees and plants were steeped in 30 ft. of the river's opaque water. As the Alpha Helix moved along looking for a landing site...
Williams quickly hypothesized tint the Rio Negro might in effect be an immense tea, pontaining infusions of plant and tree substances similar to the insect hormones. Scooping up the dark river water, Williams and his colleagues, Professors Fotis Kafatos of Harvard and David Prescott of the University of Colorado, freeze-dried and boiled the water to concentrate the chemicals in it, extracted them with solvents, then injected the resulting solution into immature cockroaches. Sure enough, the roaches all died without reaching sexual maturity...
...solved. So effective are the hormones and their plant-made equivalents, that sprays or dusts containing even minute amounts will kill any insect, including those helpful to man and essential to the functions of nature. The reason that all insects are not wiped out in the Rio Negro area is that not all of them come into contact with the insecticide-laden river. Back at work in his Harvard lab, Williams is now studying the river concentrates to learn what chemicals they contain, and how these lethal substances can be extracted separately for discriminate use against particular pests...
