...developing a 17-ft.-long, two-stage ASAT rocket launched into space from high-flying F-15 jets. The miniaturized infrared guidance device is so sensitive to temperatures that it can detect the presence of a foot-square block of ice in space at 500 miles. The F-15 can get airborne, launch its rocket and intercept a satellite within ten minutes. Concludes the congressional Office of Technology Assessment: "The U.S. air-launched ASAT weapon now undergoing testing is clearly technically superior to the present generation of Soviet ground-launched ASATs...
...test's authors claim in their article, published in the Journal of The National Academey of Sciences, that the test is so specific that it will detect only cancer-caused AFP elevation...
...seemingly legitimate documents shielding these shipments make the illegal trade difficult to detect.

Stopping the illegal trade in the future may depend not only on catching poachers in the act but on following the document trail they leave behind.

...questions as: What does a simpleminded animal, like a pigeon possess to distinguish between a tree and a person that a complicated machine, like a computer, does not? What secret of classification is mother nature hiding and, if found, could we apply that discovery to create computers that could detect the difference between addresses in a post office...
...President Reagan surprised the nation, and many experts in his own Government as well, by calling for an all-out program, along the lines of the Manhattan Project, which developed the atom bomb, to build a defense system in space. He envisioned a network of orbiting sensors that would detect a Soviet attack as soon as it was launched, then trigger giant remote-control ray guns that would destroy attacking rockets or their warheads before they could do any damage...
