Path to the brown coloration of diatoms discovered

Diatoms are microscopic unicellular algae occurring in natural waters worldwide. During photosynthesis, they take up large quantities of carbon dioxide, the primary greenhouse gas emitted through human activities, and convert ...

Learning some new steps in the energy conversion dance

At the heart of energy conversion, electrons and protons move in an intricate, coordinated dance. Chemists at Yale and in Sweden say they may have learned the steps to a new, photo-chemical rhumba.

Team reassesses greenhouse gas emissions from African lakes

The emissions of carbon dioxide (CO2) and methane (CH4)—the most potent greenhouse gases—into the atmosphere from African lakes are reassessed in a study undertaken by the Laboratory of Chemical Oceanography (FOCUS research ...

Artificial photosynthesis can produce food without sunshine

Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. This process, however, is very inefficient, with only about 1% ...
