...cosmonauts-or the ground controllers-fail to notice the opened hatch in time? "The Soyuz hatchway is not unlike a car door," Louis explained. "When the hatch is open, a signal light goes on on a console at mission control. But the light will go out when the hatch is half closed, as with a half-slammed car door." The calamity came at a time when the Russians seemed to be overtaking the U.S. in space-a remarkable comeback after they abandoned the race to land the first man on the moon.

JUST 500 years ago, Albrecht Dürer was born in Nuremberg. The anniversary has been the signal for a flurry of commemorative exhibitions across the world. In the U.S., the most impressive is a magnificent survey of Dürer's graphic work (36 drawings and 207 etchings, engravings and woodcuts) at the National Gallery in Washington...

Surveillance was so close that the exasperated captain of the Dzerzhinsky finally flashed a message: "Sir, this is not Broadway. Please find a safer place for your promenade...
...Danger Signal. Washed down from the cherry orchards by rain, those long-lived pesticides have entered the lake's food chain. When gulls eat fish, they also take in a concentrated dose of poison. As a result, they lay eggs with such thin shells that most do not hatch. "Gulls here produce .42 chicks per nest compared with 1.22 chicks per nest in less polluted areas," Scharf explains. He fears for the human population too. "The Government has linked DDT with cancer in laboratory experiments. We know that it has the same type of effect on mammals...
...signal has not gone unheeded. In 1969, Michigan banned sales of DDT; Traverse City's cherry growers also stopped using related poisons. Even so, the pesticides already in the environment will remain potent for years, and Lake Michigan is surrounded by home gardeners who use other persistent poisons. All the citizens of Traverse City can do now is rake their reeking beaches and hope for a miraculous return of the gulls-the area's best and cheapest garbagemen...
