Diatom genome reveals key role in biosphere's carbon cycle

...and produce oxygen. And they are an important food source 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.

A treatment, not a cure: Calcium silicate neutralizes an acidic stream

...rically used various forms of limestone, a natural source of calcium carbonate. Its neutralizing effects are short-lived, however, and can generate extreme fluctuations in water chemistry. Recognizing the limitations of limestone, Likens and colleagues looked to another material to neutralize an acidified s...
