    For Jennifer Chayes, math is a 'native tongue'
    Much of the code that describes the inner workings of social networks, helps apps predict your musical interests, and underlies innovations in AI traces back to advances in mathematical theory and data science that fundamentally describe how massive networks behave.Jennifer Chayes helped create that field of math. She also spent 20 years at Microsoft building interdisciplinary research labs. Now, at UC Berkeley, her interests lie in using machine learning to work on topics like materials science, cancer immunotherapy, ethical decision-making, and climate change. She joins Flora for a wide-ranging discussion about math, networks, AI, academia, and her path between them. Guest:Dr. Jennifer Chayes is the dean of the College of Computing, Data Science, and Society at UC Berkeley.Transcript will be available after the show airs on sciencefriday.com.

    What an mRNA melanoma vaccine may mean for cancer treatment
    A new mRNA vaccine for melanoma is making headlines. Moderna and Merck recently announced results from their clinical trial suggesting that this new vaccine, in combination with the cancer drug Keytruda, reduced recurrence rates in patients. The companies have not yet released full data from the trial. So, how does the vaccine work? And does this mark the beginning of a new era of cancer treatments using mRNA vaccine technology? Ira talks with physician Michael Postow, whose patients were part of the drug trial at Memorial Sloan Kettering Cancer Center. Guest: Dr. Michael Postow is chief of the melanoma service at Memorial Sloan Kettering Cancer Center.  Transcript will be available after the show airs on sciencefriday.com.

    Why it's so hard to tell the age of a fungus
    When you see a mushroom popping up from the forest floor, that mushroom is just the tip of the fungal iceberg for a vast world beneath the surface. But the nature of fungal life makes it hard to answer some basic questions. What exactly does it mean to be one individual organism? And how do you tell how old a fungus is, when parts of it can recycle, regenerate, and grow again? Flora talks with fungal researcher Kristin Aleklett about the challenge of fungal age, and how researchers are trying to better understand what fungi are doing in the world under the ground. Guest: Dr. Kristin Aleklett is a researcher at Lund University in Sweden. Transcript will be available after the show airs on sciencefriday.com. Subscribe to this podcast.

    The power of the stories we tell about the ocean
    There’s been wave after wave of bad news about the ocean: warming temperatures, overfishing, acidification, coral bleaching. But in the last few years, there have also been some big wins for the big blue—as well as a narrative shift, in which the ocean itself has almost become its own larger-than-life character in conservation conversations. So how should we think about the future of the seas? And how do the stories we tell about the ocean shape how we think about it? Flora chats with marine biologist Helen Scales, author of “What the Wild Sea Can Be,” which is the Science Friday book club pick for September and October. Check out the SciFri Book Club to read along. Read an excerpt from “What the Wild Sea Can Be: The Future of the World’s Ocean.” Guest: Dr. Helen Scales is a marine biologist and author of several books, including “What the Wild Sea Can Be: The Future of the World’s Ocean.” Transcript will be available after the show airs on sciencefriday.com.
