How do most organisms in the natural world communicate? It's through the language of chemistry. Scripps Institution of Oceanography marine biologists Bradley Moore and Natalie Grayson explore how ocean life uses molecules as a language. Examples include a pigment that lets squid and octopus change color for camouflage, a coral and its microbial partners that produce biologically active compounds, and a chemical now in phase three human clinical trials to treat glioblastoma, an aggressive cancer of the brain. Their research has applications for new materials in biotech, and improving the food supply and human health. Series: "Jeffrey B.
