...August Erin began taking Luvox for her obsessive-compulsive disorder, and in early October she started on Adderall, a combination of various stimulants. "For 4 1/2 weeks, we've seen heaven on earth," says Tim. "We have a semblance of family life." They spent a day recently at a church festival. "There were a lot of people there," Charlene says. "Normally that would produce a lot of anxiety for someone who has ADHD. But Erin had a great time." She can play games longer, take car trips, do homework. "I have a child I can relate to who is hearing...
...large object, five or six miles across, blasted a 120-mile-wide crater at the tip of what today is Mexico's Yucatan peninsula. They also know that the impact, or more accurately, the worldwide, sunlight-blocking shroud of dust it kicked up, wiped out some 70% of the earth's plant and animal species--including the dinosaurs. But what, precisely, was the object that sealed their fate...
...fact that the meteorite exists at all, says Kyte, also strongly suggests that it came from an asteroid, not from a comet, as many scientists still believe. He notes that comets strike the earth at such high speeds--many of them well over 100,000 m.p.h.--that they are usually completely melted and vaporized. But a typical asteroid hits at less than half that speed, and some fragments often survive. So why did this one turn up 5,400 miles away from the Yucatan impact site? Kyte believes it was flung by the explosion high above the atmosphere...
Confident that they will learn still more about creatures that ruled the earth unchallenged for more than 200 million years, Chiappe and his colleagues plan to return to their dinosaurian mother lode next March. Says Coria: "This discovery opens large doors that had remained closed for years." To make sure the site won't fall prey to contemporary egg snatchers, the provincial government has declared it a protected "paleontological park" and is keeping it under full-time guard...
...launch control center 36 years ago, when John Glenn made his first orbit of the earth [SPACE, Nov. 9]. I spent 20 years in manned space flight, and am now 65 and retired. When I was 48, I applied to become a mission specialist, but, alas, was deemed "too old." Glenn's second space trip has given me new hope! Maybe in 12 years, when I'm 77 like he is now, space travel will be available to anyone with the health and determination to go. If that happens, we'll look back on this mission as the milestone that...
