When most people look out at the ocean, they see a vast, nearly empty expanse of water. Associate Professor of Biology Oscar Sosa sees something more dynamic and mysterious. To him, the ocean is “a soup of microbes and organic molecules doing all kinds of things together and independently.” This year, Sosa and five former University of Puget Sound students coauthored a paper in Nature Microbiology alongside collaborators at the University of Washington and Whitman College outlining a newly discovered metabolic pathway used by marine organisms.
