Iran seems to be moving toward an atomic bomb; North Korea reportedly could build a half dozen; and terrorist attacks have revived the specter of a faceoff between nuclear-armed Pakistan and India. Yet the Comprehensive Test Ban Treaty, forbidding nuclear testing, has failed to win ratification from the U.S. Senate and lawmakers of some other nations. Opponents say scientists cannot reliably detect clandestine tests: Why should we go along, if others can cheat?

In 1968, 14-year-old Paul Olsen of suburban Livingston, N.J., and his friend Tony Lessa heard that dinosaur tracks had been found in a nearby quarry. They raced over on their bikes. "I went ballistic," Olsen recalls. Over the next few years, the boys uncovered and studied thousands of tracks and other fossils there, often working into the night. It opened the world of science to Olsen; he went on to become one of the nation’s leading paleontologists.

Climate Scientist Who Sounded Early Warnings Is Still At Work
Wallace S. Broecker, a geochemist at Columbia University’s Lamont-Doherty Earth Observatory, has received the newly founded Frontiers of Knowledge Award in Climate Change Research, one of the world’s largest science prizes. An international jury awarded Broecker the $527,000 prize, from Spain’s Banco Bilbao Vizcaya Argentaria Foundation, for sounding early alarms about climate change, and for his pioneering work on how the oceans and atmosphere interact.

But Global Warming May Have Helped Override Some Recent Eruptions
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics—but suggest that such effects may have been masked in the 20th century by rising global temperatures
