Up from the depths: How bacteria capture carbon in the 'twilight zone'
Located between 200 and 1,000 meters below the ocean surface is a "twilight zone" where insufficient sunlight penetrates for microorganisms to perform photosynthesis. Details are now emerging about a microbial metabolic pathway ...

New images of marine microbe illuminate carbon and nitrogen fixation
Trichodesmium is unusual among marine microbes because it both "breathes" carbon dioxide like plants, while also taking nitrogen gas from the air and "fixing" it into a fertilizer of the seas.
