TL;DR: Two mesoscale experiments, designed to investigate the effects of iron enrichment in regions with high and low concentrations of silicic acid, were performed in the Southern Ocean, demonstrating iron's pivotal role in controlling carbon uptake and regulating atmospheric partial pressure of carbon dioxide.

TL;DR: The agreement between photochemical action spectrum and spectrophotometric difference spectrum supports the conclusion that the CO-binding pigment is the terminal oxidase of mixed function oxidase systems of mammals.

TL;DR: Approaches to identifying more of the earth’s biological diversity; understanding how biological, geophysical, and geochemical processes interact; and presenting scientific knowledge in time to contribute to and achieve the 2010 target are described.

TL;DR: It is found that restoring 15% of converted lands in priority areas could avoid 60% of expected extinctions while sequestering 299 gigatonnes of CO 2 —30% of the total CO 2 increase in the atmosphere since the Industrial Revolution.

TL;DR: Oxidative demethylation of the secondary carcinogen dimethylnitrosamine (DMN) by isolated mouse liver microsomes and the activation of DMN to a bacterial mutagen followed similar kinetics, indicating that both microsomal metabolism and activation ofDMn to a mutagen are cytochrome P-450 dependent.
