Whenever Kataoka spots a fine specimen, he not only takes pictures but gives a pep talk as well. "Let's build more scarecrows," he tells bemused farmers. "Yours is great, but you could improve next year by adding a little more color here and a little more shape there...
...remarkable. It lay in a countryside of desert valleys in central Utah that 150 million years ago was a lush tropical shore along an inland sea, inhabited by huge flesh-eating dinosaurs. The area has thus yielded a rich supply of plant and animal fossils. Examining a specimen of the fossil under a microscope, Paleobotanist William D. Tidwell of Brigham Young University recognized the unmistakable cellular structure of the palm...
...case of users, the test turns up traces of barbiturates, amphetamines and morphine, which the body metabolizes out of heroin. The tests have led to a burgeoning business for private laboratories; some do several hundred urinalyses a day, at $4.50 each. Even these tests are not foolproof. If a specimen shows a hint of quinine, which is often used to cut heroin, the applicant can be refused -but he could have picked it up simply by drinking a gin and tonic, which also contains quinine. Another drawback is that the tests cannot detect heavy users of marijuana because it leaves...
...small, lemon-sized rock from the Ocean of Storms resembled an ordinary piece of granite, but it was, in fact, unlike any earthly specimen-or any of the other lunar material brought back by Apollo 12. It contained 20 times as much radioactive uranium, thorium and potassium as comparable amounts of other moon material and was the oldest lunar specimen yet obtained.

Scientists hope that further...

In former times of trouble, even America's severest critics usually shared the notion that the disappointing child they were shaking heads over was still a bouncing specimen; there was plenty of time to reform its ways. Now, little time seems left. All these skilled critics not only reckon on the chance of an American apocalypse; they simply take for granted that most Americans are living with the shadow of this new apprehension. Read together, their examinations...
