For the past 24 years, Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, has been developing a complex computer model to study air pollution, energy, weather and climate. A recent application of the model has been to simulate the development of hurricanes. Another has been to determine how much energy wind turbines can extract from global wind currents.
Scientists and environmentalists have long warned that biofuel production could have troubling land-use consequences, and now there’s new research that appears to confirm some of the worst fears.
A University of Oregon scientist has made the controversial claim that ancient multicellular fossils long thought to be ancestors of early marine life are in fact land-dwelling lichen or other microbial colonies.
Researchers at the University of Washington have determined that "some" microbial life migrated from the Earth's oceans to land some 2.75 billion years ago.
