Researchers have successfully launched a new satellite that is designed to study the planet's forests and "provide unprecedented insight" into how those regions impact the Earth's carbon cycle ...

and heterotrophic bacteria. The products of these organisms feed back into the carbon cycle in marine sediments, where they may be consumed by other microbes.

This, in turn, was the first evidence we’ve found of the ancient Martian carbon cycle. “Now we have evidence that confirms the models,” Tutolo claims. The carbon from the atmosphere was ...

as part of what is called ‘the global carbon cycle.’ A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. The IAEA Environment Laboratories apply nuclear and ...
