Scientists uncover how plants invaded the land, learned to survive heat, drought
December 13, 2007 04:21 PM - UC Berkeley Newswire
Berkeley -- Some 400 million years ago, on a lifeless lakeshore lapped by waves, floating algae learned to survive in the open air and launched an invasion that transformed the Earth into a green paradise. The secrets of these first steps onto land are now being revealed thanks to the sequencing of a modern descendent of these first land dwellers, a dainty moss called Physcomitrella patens that sprouts on recently exposed shorelines, quickly fruits, and then dies.

Asian desert dust found over western United States
December 13, 2007 01:14 PM - Vince Stricherz, University of Washington Newswire
Seattle, Washington - It has been a decade since University of Washington scientists first pinpointed specific instances of air pollution, including Gobi Desert dust, traversing the Pacific Ocean and adding to the mix of atmospheric pollution already present along the West Coast of North America.
Now a UW researcher is finding that dust from the Gobi and Taklimakan deserts in China and Mongolia is routinely present in the air over the western United States during spring months. "We are interested in Asian dust that comes across the Pacific because particles can have an impact on health, as well as on visibility," said Emily Fischer, a UW doctoral student in atmospheric sciences.

Managing manure in California

While that keeps the state's 1.7 million dairy cows busy making milk, they also produce plenty of manure. The manure is filled with nutrients that farmers can use as fertilizer, but it also can pollute the environment.

Oil major Shell said on Tuesday it would build a pilot facility in Hawaii to grow marine algae from which it would extract vegetable oil that would be converted into a form of diesel for use in trucks and cars.
