Leaf Senescence: More Than a Color Show
Leaves change colors during the fall as part of a process called leaf senescence. Why is this process important, and what causes it?

What happens when the largest carbon and silicon sink isn’t actually as big as scientists originally thought? Chemical oceanographers Manuel Maldonado and his colleagues have come up with a new way to study the oceans most important chemical cycles and the surprisingly important role of the simple sea sponge.

While we have a pretty good idea of the important processes, could we be missing another “big” piece of the puzzle? In this study, scientists try to figure out if elephants are having an impact on the carbon cycle where they live.
