Mark Zuckerberg's philanthropy is about to reach new depths: The bottom of the ocean.

Facebook's CEO has invested more than $10 billion in a variety of causes, including a big chunk to the formation of a Bay Area-based research center called Chan Zuckerberg Biohub. Biohub, which is also backed by the Zuckerberg's pediatrician-wife Priscilla Chan, has $600 million in committed funds to invest in researchers with bold ideas.

For its next phase of investment, the group is providing $14 million in funds to several new programs ranging from aging to cardiovascular disease.

One of the coolest among them is dedicated to understanding the great mysteries of ocean.

Stephen Palumbi is one of the marine biologists with new backing from the Biohub.

Palumbi, who runs a lab at Stanford, has spent years studying the giant corals that live for more than a thousand years. He is looking to understand how they get to be as heavy as a blue whale in their long lives, while proving to be relatively resilient compared to other species.
