Nautilus

Lina Zeldovich grew up in a family of Russian scientists, listening to bedtime stories about volcanoes, black holes, and intrepid explorers. She has written for the Smithsonian, National Geographic, Reader’s Digest, the New York Times and other publications. Her most recent book, <a href="https://us.macmillan.com/books/9781250283382/thelivingmedicine">The Living Medicine</a>: How a Lifesaving Cure was Nearly Lost and Why it Will Rescue Us When Antibiotics Fail, chronicled the history of phage therapy and was longlisted for the PEN America Literary Awards.
