A new study co-authored by a Tulane University geoscientist shows that human efforts to tame the Mississippi River may have had an unintended positive effect: more rapid transport of carbon ...
Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abund...
As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the oceans. Now researchers from the University of Connecticut and other institu...
