There was some speculation many years ago, in the 1970s, that because women had greater fat stores, they would outlast men in long-distance events. We have a famous race in South Africa, the 90-km (56-mi) Comrades marathon. Some years ago we wrote a paper in which we made the case that if a man and a woman could run a [standard 42-km (26-mi)] marathon in the same time, the woman would likely win the longer Comrades race by about an hour. She'd be about an hour faster...
...weight, then women get a huge advantage over longer distances, simply because they have less mass to move around. But once you match for weight, the men run about 10% faster. We've really shown now that at any distance between 100 m up to 1,000 km (620 mi), women are consistently somewhere between 9% and 11% slower than men. We expect that until women can run 100 m as fast as men, women won't beat men even...
...Cambodian troops are facing off over the 11th century Preah Vihear temple on the countries' shared border. The feud follows the temple's designation as a UNESCO World Heritage site in early July. Thailand says the map used in Cambodia's UNESCO application improperly places some 1.8 sq. mi. (4.7 sq km) of land near the temple in Cambodian territory. (Cambodia legally owns the temple itself.) Opposition leaders are using the issue to pressure Thailand's embattled government, which initially endorsed the application, and the Foreign Minister has resigned as a result. Cambodia, calling the situation an "imminent state...
...expand the range of territory protected by marine reserves - national parks of the deep. And here the Bush Administration - usually anything but environmental - deserves real credit. With a stroke of a pen in 2006, President George W. Bush created the Papahanaumokuakea Marine National Monument, a 140,000 sq. mi. protected area northwest of Hawaii. Larger than every other national park in the U.S. combined, the monument protects 10% of the shallow coral reef habitat in U.S. territory. These kind of reserves need to be expanded, to limit the influence of human activity on delicate corals...
Sometime next year, a California start-up called Climos plans to experiment with the technique, fertilizing about 4,000 sq. mi. (about 10,000 sq km) of ocean. The goal is not to prove that the iron makes the plankton grow but to determine how much carbon this takes out of the atmosphere and for how long. "When we add iron, we create plankton blooms," says oceanographer Ken Buesseler of the Woods Hole Oceanographic Institution, who led an earlier, smaller iron-seeding test, "but a lot of that just dies and decomposes" at the surface. Only when organic matter snows...
