Double triumph in stem cell quest

...he US. By contrast, there is a virtually limitless supply of existing ESCs for fusion with adult cells. Then there is the ethical issue, which is again exercising Congress. With Verlinsky's method, federally funded researchers could try to derive stembrids using already-approved ESC lines. Verlinsky still...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...in most of the world's oceans is controlled by the supply of nutrients to the surface water," wrote the authors, who are all affiliated with Stanford's School of Earth Sciences. "The Gulf of California contains some of the highest nutrient concentrations in the oceans and sustains highly elevated rates of b...

The public DNA sampling is part of a larger undertaking to unravel the origins and migratory history of mankind thousands of yea...

Currents could disrupt ocean food chain

...om the mixing of waters constantly replenishes the supply of phytoplankton at the surface, forming a rich nutrient source at the bottom of the marine food web. There is growing concern by a number of scientists, however, that higher levels of human-generated carbon dioxide could increase water and air temp...

Fungus-farming termites descend from an African rain forest Eve

...i. By offering those domesticated fungi a constant supply of growth substrate, and humid, highly buffered, rain forest like climatic conditions in their nests, termites have been able to export this rain forest process into the savannas. The marrying of termites and fungi in a mutualistic symbiosis has thus...
