Ocean acidification threatens cold-water coral ecosystems

... are home to more than 1,300 species of animals, a diversity rivaling some better known tropical coral reefs. Until now, scientists believed bottom trawling ?a commercial fishing method in which vessels drag large, heavily weighted nets across the bottom ?to be the greatest threat to cold-water corals. Now, h...

Wisconsin scientists grow two new stem cell lines in animal cell-free culture

...ts say additional lines are needed to ensure broad diversity in order to better match patients with cells and gain a more comprehensive understanding of disease as it affects people with different genetic backgrounds. The original five stem cell lines derived by Thomson in 1998, like many subsequently derived...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort
