...brother, followed by other family members. Currently on leave from NASA, she is a visiting professor at Stanford, where her husband Mark Jacobson is an associate professor of engineering. The two are collaborating on a project that's probing the likely atmospheric impact of a broad-scale switch from fossil fuels to hydrogen. The results, she hopes, will provide society with the information it needs to make rational decisions about global warming. --By J. Madeleine Nash
...issue is the College’s purchase of renewable energy certificates (RECs)—tradable units that represent the output of a wind farm somewhere in the country. If the referendum passes, most of Harvard’s actual electricity would still come from nuclear and fossil fuel power plants in New England, while the premium it would pay for the certificates would go to renewable energy sources in Texas, Colorado and Minnesota, among other states...
Yang's globe trotting reflects just how powerful China's thirst for fossil fuels has become. A booming but energy-inefficient economy and an emerging middle class in love with cars and other modern conveniences have caused energy demand in China to soar. The nation's oil imports have doubled over the past three years and surged nearly 40% in the first half of 2004 alone, pushing the country past Japan to become the world's second largest oil consumer, behind...
...pair did this by combining their experiments with fossil evidence to show that many distinguishing features of the human anatomy, such as our large rear ends and the large distance between our shoulders and heads, were designed for running—and have little bearing on walking ability...
...favors speedy predators like velociraptors as the direct ancestors of modern birds, both Chiappe and Norell argue that the birds' forebears could just as easily have been troodontids like Mei long or even oviraptors, another related type of dinosaur. (Several years ago in Mongolia, Norell and colleagues unearthed a fossil oviraptor sitting on its egg-filled nest.) And then there's also the open question of how flight evolved. Mei long, says Chiappe, was clearly sleeping on the ground. But if flight began as flying-squirrel-like glides out of trees, he wonders, "wouldn't it have been safer resting...
