...this question were divided into two teams. The first group, known as the "phase retrieval" team, relied on the data streaming down from Hubble. By comparing images of stars with optical theory, the researchers could calculate the apparent distortion of Hubble's mirror. Their work was confirmed by the "fossil record" team, which went back to the source of the flawed mirror, a Connecticut plant now owned by Hughes Danbury Optical Systems. (At the time of the manufacturing mistake, the facility was part of Perkin-Elmer Corp.) Like archaeologists looking for the missing link, the optical sleuths pored over...
Gould's incredible mastery of the scientific and the literary realms makes him a rare gem in his field--in his world, he would be a rare fossil find. He can make science accessible, important and compelling all at once, while other writers struggle with any one of these tasks. Like the quirky and unpredictable sequence of evolution which Gould defends, his wacky and often random metaphors serve him well in the creation (evolution might state it better) of a unified set of essays...
This energy costs environmentally: Generating electricity involves burning fossil fuels or running a nuclear reactor or hydroelectric plant. These processes can result in many forms of pollution: acid mine drainage, oil spills, natural gas leakage, toxic waste and air pollutants. Energy efficient lighting can decrease the amount of energy needed to meet lighting electricity demand by more than 50 percent...
...FOSSIL RECORD IS clear. Time and again during the nearly 4 billion years that life has existed on Earth, it has been assailed by global catastrophes that have caused the wholesale extinction of animals and plants. Over the past decade evidence has been mounting that many of these calamities were caused . not by long-term climatic changes, volcanism or disease, but by large asteroids or comets smashing into Earth...
Although the ancient hunter lacked the flexible lower jaw and other advanced features of its more ferocious descendants, the overall shape and internal structure of its bones provide strong evidence that the beast was a true dinosaur. "This fossil confirms our suspicions that dinosaurs began as small, carnivorous, bipedal animals," says Paul Sereno, an assistant professor of anatomy at Chicago and a leader of the expedition. "We are just a couple of steps away from the ancestor of all dinosaurs." The scientists named the find Eoraptor, or "dawn stealer," because it appeared at the dawn of the dinosaurs and, considering...
