Elephant tusks, rhino horns and leopard skins confiscated from poachers were a common sight in the "ivory room" of the Kenyan Game Department's Mombasa office, where Werikhe used to work. But a pair of 50-kg (110-lb.) tusks brought in one day by a game warden induced him to start his one-man crusade. "Being an African, I see wildlife as part of my heritage," Werikhe says. "If wildlife goes, then part of me is dead. I wanted to campaign for wildlife in my own private...
...twelve-year-old leader of a band of schoolchildren in Nagano, Japan, who have already saved 40 acres of forest land in Costa Rica. On their way to and from school, they collect old newspapers and empty aluminum cans for sale to a recycling plant at 63 cents per kg. The proceeds, augmented by donations from parents and neighbors, are sent to the International Children's Rainforest Program, which buys and preserves virgin parkland at the rate of $50 an acre. So far, Jiro and his friends have raised more than...
...skies over California last week, a launch took place that broke all the rules. A diminutive rocket named Pegasus, built by a Virginia-based entrepreneurial firm called Orbital Sciences, dropped from under the wing of a B-52 and carried into orbit a small 200-kg (450-lb.) satellite, one of a new type of craft that promises to bring space history full circle. Called lightsats, the new payloads pack as much function into a few hundred kilograms as satellites many times their size. At $8 million a launch, they could open space to new military and industrial uses...
...shrinkage has only begun. In July a second Pegasus is scheduled to launch seven 22.5-kg (50-lb.) communications satellites the size of car tires. And scientists are already dreaming about peppering space with swarms of "microspacecraft," each no bigger than a coffee...
...alone, Antarctica's scientists have carried out dozens of unique experiments. In the McMurdo Sound area a group of geologists camped out in the bitter cold of the Royal Society mountains, looking for evidence of the ebbing and flowing of glaciers in Antarctica's past, and biologists drew 50-kg (110-lb.) fish from ice holes to study the unique organic antifreeze that keeps these sea dwellers alive. Volcanologists braved the knifelike winds and choking fumes atop Mount Erebus to learn what kinds of gases and particles Antarctica's largest volcano emits. At Williams Field, a runway on the Ross...
