Chemoautotrophy In Subzero Environments And The Potential For Cold-adapted Rubisco

by Keith Cowing

The act of fixing inorganic carbon into the biosphere is largely facilitated by one enzyme, Rubisco. Beyond well-studied plants and cyanobacteria, many bacteria use Rubisco for chemolithoautotrophy in extreme environments […]

Study Resolves The Diatom Tree Of Life

by Keith Cowing

Trees get most of the love, but diatoms, a group of photosynthetic microalgae, produce 20% of Earth’s oxygen and are the foundation of aquatic food webs. The prevalence and diversity […]
