Diatom genome reveals key role in biosphere's carbon cycle

...ource for many other marine organisms. Scientists would like to better understand how these organisms react to changes in sea temperatures, the amount of light penetrating the oceans, and nutrients. "Oceanographers thought we understood how diatoms use nitrogen, but we discovered they have a urea cycle, ...
