Investigation of oceanic 'black carbon' uncovers mystery in global carbon cycle
An unexpected finding published today in Nature Communications challenges a long-held assumption about the origin of oceanic black coal, and introduces a tantalizing new mystery: If oceanic black carbon is significantly different from the black carbon found in rivers, where did it come from?

Study finds sex bias in bird conservation plans
After pairing up and raising chicks, males and females of some bird species spend their winter break apart. At the end of their journey to Central or South America, you might find mostly males in one habitat, and females in another. Yet conservation strategies have typically overlooked the habitats needed by females, putting already-declining species in even more peril.
