...Harvard researcher. Skilled immigrants who have historically stayed in the United States have proved a key source of innovation for the nation’s economy, according to Vivek Wadhwa, a Law School senior research associate who led the study. Wadhwa said 52 percent of Silicon Valley startups and a quarter of startups nationwide were started by immigrants in the last decade. But as the U.S. job market stagnates amid an unprecedented recession and economic opportunities increase in fast-developing nations such as China and India, immigrants have begun returning home, depriving the United States of thousands of skilled workers...
...explain what you do? Let me walk you through what's happening at our Alaska volcano observatory, one of five in the country. [The others are in Yellowstone National Park, Washington State, Hawaii, and Long Valley, California.] We have seismic networks and other geophysical equipment monitoring a number of volcanoes in Alaska, including Redoubt Volcano, 100 miles southwest of Anchorage. The volcano is showing a lot of signs of unrest that probably presage an eruption. So we look at seismic data, webcams, radar data and satellite imagery; we make overflights in airplanes to observe; we take gas measurements...
...eruption. If you've got volcano unrest and you don't know the extent of the eruption, you really tend to overreact when you don't need to. We can also give practical information - telling people about ash flow or when a mudflow is coming down a river valley - that has really high stakes. In 1985, an entire town in Colombia, Armero, was obliterated and [about] 23,000 people were buried alive when a relatively small eruption melted snow and ice on a volcano and sent it rushing down this river valley. Scientists knew the eruption had occurred...
...First, the Taliban in the Swat Valley announced an indefinite cease-fire, but only after the army had agreed to halt its counterinsurgency operations and the government caved in to the militants' demand for the imposition of Islamic law. Then it emerged that the Taliban and the army would both be observing a four-day truce in Bajaur, the tribal area along the Afghan border that has seen the fiercest fighting in Pakistan's domestic campaign against extremists. And on a more ominous note, last weekend at an undisclosed location deep in Waziristan's mountains, Pakistani Taliban commander Baitullah Mehsud...
...Swat Valley in northwestern Pakistan is now the domain of Taliban militants. Bombings have become commonplace in many towns, as have hostage-takings and public hangings. The craftwork is gone. Local music stations have been replaced with extremist radio propaganda. Women have been banned from walking the streets in many locations, and at least a dozen of the valley's once bustling resorts have been forced to close, including Malam Jabba, which militants torched last year. "I have many nice memories there, so I am very sad about it," says Nisar, a photographer from Lahore. Even as cross-border tensions...
