Biological Hydrogen Production: Not So Elementary
Article Abstract:
Hydrogenase is the family of enzymes that catalyze the interconversion of the smallest molecule, hydrogen gas. Researchers have used x-ray crystallography to determine the structure of iron-only hydrogenase from a hydrogen-producing, anaerobic bacterium. The mechanisms underlying natural hydrogen metabolism and their possible exploitation by catalytic chemists are discussed.

Biological implications of the middle Miocene Amazon seaway
Article Abstract:
Research indicates that an interior seaway occupied the Amazon Basin 10 million years ago. The existence of this sea in the middle Miocene explains the number of marine-derived species in the Amazon River.

Biological nitrogen fixation and model chemistry
Article Abstract:
The process by which nitrogenases fix nitrogen in organisms such as plants and bacteria is still poorly understood. A recent study on the reaction of N2 with a mononuclear zirconium complex is described.
