There's so much left to learn about the sea and its organisms. Could the ocean be the source of the next drug to change medicine?
Despite recent discoveries, we still know so little about the vast biodiversity of the marine environment and its potential. What secrets does the sea hold that could revolutionise the way we treat the many diseases that remain stubbornly unsolved?
Marine microbiologist Dr Jeanette Davis was part of a team that discovered a marine bacterium that helps fight cancer. She joins us in The Garden to explain how scientists approach the search for new drugs in the extreme and little-understood deep sea environment, and why the next big development in cancer treatment might come from a source you probably wouldn't expect.
