Carbon dioxide (CO₂) pollution drives climate change, warming the planet and threatening human survival. Plants naturally ...

Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth—and it could help assess which other planets can ...

(A) Photosynthesis in land plants fixes atmospheric CO2 (inorganic carbon) as organic carbon, which is either stored as plant biomass or in soil, or is decomposed back to CO2 through plant and ...

Ancient microbes illustrate a particular kind of respiration in which carbon dioxide and hydrogen are combined to form acetic ...

Autotrophs participate in the carbon cycle by fixing carbon dioxide to produce the biomass that all other organisms use for life. Four autotrophic carbon-fixation pathways were already known and ...

Ocean ecosystems play a critical role in carbon storage and oxygen generation. Some of these ecosystems are under threat; others remain unexplored. Understanding how key players such as whales ...

In 2022, the Webb telescope detected unequivocal evidence of carbon dioxide in the atmosphere of a distant exoplanet called WASP-39b. But that detection was made indirectly, so the latest ...

Carbon, a building block of life, is constantly moving through different environmental compartments such as biota, the atmosphere, the ocean, soil and sediment, as part of what is called ‘the global ...

Carbon dioxide (CO₂) pollution drives climate change, warming the planet and threatening human survival. Plants naturally turn CO₂ into oxygen (O₂) during photosynthesis, but their ...
