229. Dr. Charan Ranganath with Chantel Prat: Unlocking the Mysteries of Memory
We all get frustrated with our inability to remember people’s names, find our keys, or recover a lost computer password. Fortunately, these experiences are not reflections of our broken brains, but the fact that the brain didn’t evolve the complex mechanisms of memory so that we could remember that guy we met at that thing. In fact, human memory is so much more than a personal archive or database. It’s a powerful and pervasive force that runs through all human experience and to a shocking degree makes us who we are – not just a record of the past, but as a determinative force in the present. Dr. Charan Ranganath, a leading memory researcher, unveils the surprising aspects of human memory in his new book Why We Remember revealing how memory shapes our lives, impacts our decisions, and holds the key to understanding our past and planning for the future. This science narrative explores the unseen influence of memory on emotions, choices, and well-being, offering valuable insights for a broad audience, including those interested in staying mentally sharp, individuals dealing with trauma, parents, educators, and anyone seeking to make more mindful decisions. Drawing on over two decades of research, Dr. Ranganath’s book challenges common misconceptions about memory, delivering a paradigm-shifting perspective that’s both informative and life-changing. Charan Ranganath is a Professor of Psychology and Neuroscience and director of the Dynamic Memory Lab at the University of California at Davis. For over 25 years, Dr. Ranganath has studied the mechanisms in the brain that allow us to remember past events, using brain imaging techniques, computational modeling, and studies of patients with memory disorders. He has been recognized with a Guggenheim Fellowship and a Vannevar Bush Faculty Fellowship. Chantel Prat, author of The Neuroscience of You, is a Professor at the University of Washington with appointments in the Departments of Psychology, Neuroscience, and Linguistics, and at the Institute for Learning and Brain Sciences. Her interdisciplinary research investigates how variable brain designs combine with our lifetime of experiences to shape the unique way each person understands the world and operates in it.

227. Jeffrey McKinnon: Our Ancient Lakes
Discover the unexpected diversity, beauty, and strangeness of life in ancient lakes — some millions of years old — and the remarkable insights they yield about the causes of biodiversity. Most lakes are less than 10,000 years old and short-lived, but there is a much smaller number of ancient lakes, tectonic in origin and often millions of years old, that are scattered across every continent but Antarctica: Baikal, Tanganyika, Victoria, Titicaca, and Biwa, to name a few. Often these lakes are filled with a diversity of fish, crustaceans, snails, and other creatures found nowhere else in the world. In Our Ancient Lakes, biology professor Jeffrey McKinnon introduces the remarkable living diversity of these aquatic bodies to the general reader and explains the surprising, often controversial, findings that the study of their faunas yield about the formation and persistence of species. Shining a light on a class of biodiversity hot spot equivalent to coral reefs in the ocean or tropical rainforests on land, Our Ancient Lakes chronicles the often singular wonders of these venerable water bodies. Jeffrey McKinnon grew up reading Gerald Durrell and Farley Mowat, absorbing Jacques Cousteau and Marlin Perkins’ teachings from the TV, and watching animals in the ditches, farmyards, forests, and tidepools of Western Canada. He received his BSc from the University of British Columbia and his Ph.D. from Harvard University. A Professor of Biology at East Carolina University, his research has taken him to every continent but Antarctica and has appeared in journals including Nature and the American Naturalist.

223. Britney Daniels: The Cost of Caregiving
Have you ever wondered what your nurses’ lives are like outside of the hospital? In a new memoir, Journal of a Black Queer Nurse, Nurse Britney Daniels divulges the details of her day-to-day life. From braving the front lines during the COVID-19 pandemic to giving her own clothes to a patient who was unhoused to transporting bodies to overflowing morgues (and experiencing her own physical ailments as a result), to advocating for patients of color in the face of systemic racism and more, these unseen moments as a marginalized nurse inform her authorship while helping to illuminate just some of what goes on behind the scenes. Nurse Daniels identifies as a Black, masculine-presenting, tattooed lesbian from a working-class background. For the last five years, she has worked as an emergency room nurse. What began as a personal diary also became an instrument of healing from perpetual trauma wrought not only by what she witnessed in her career but stemming from how much she dared to care. The book may make you feel sadness, humor, anger, a sense of injustice, or all of the above in this candid account that exposes some unflattering truths about health care in the United States. Journal of a Black Queer Nurse strives to reveal how true care goes beyond treating the physical body. Daniels asserts that it involves listening to and understanding patients and it demands that nurses — especially nurses of color — also be warriors. Britney Daniels, RN, MSN is a Black queer travel nurse and social advocate who has worked in hospital emergency rooms all over the US. Daniels holds a bachelor’s and master’s degree in nursing with a concentration in nursing leadership. She is currently working on her Doctorate of Nursing Practice degree.

222. Understanding Your Pelvic Floor With Dr. Peg Maas, DPT
Take a moment to appreciate the humble but essential set of muscles we call the pelvic floor. When the pelvic floor is working well, our bladder, bowels, and sexual functioning are more likely to be trouble-free. If they aren’t working well, people can experience incontinence, constipation, pain, and a host of other troubles. Out of embarrassment or discomfort with the topic, people often turn to unreliable sources for information and help. Dr. Peg Maas, DPT, is a Board Certified Pelvic and Women’s Health Physical Therapist who has worked and taught in the field for over 30 years. She works with people of all genders and ages, bringing useful pelvic health information to those who are ready to learn — no matter their comfort level with the topic.

221. Cat Bohannon with Bonnie Garmus: The Evolution of the Female Sex
Why do women live longer than men? Why do women have menopause? Why do girls score better at every academic subject than boys until puberty, when suddenly their scores plummet? And does the female brain really exist? Considering the science and data collection methods we currently have, it is somewhat of a wonder that there is so little known about biology as it relates to sex, as well as our behavior. Author and Researcher, Cat Bohannon, argues that these questions should have been investigated decades ago, with a level of thoroughness and care that is still lacking in mainstream science. Bohannon points to the fact that societal attention has been on the male body for so long, that even natural occurrences like menopause, are considered a medical mystery. In her debut publication, Eve: How the Female Body Drove 200 Million Years of Human Evolution, Bohannon examines the evolution of the female sex. From the development of breastmilk, initially in mammals no larger than a field mouse, to the first placental mammals, to the way C-sections in the industrialized world are altering women’s pelvic shape, Bohannon brings hard science and a passionate curiosity to the subject of female biology. Please join us as Town Hall as Cat Bohannan makes the case for a greater understanding of the female body. Cat Bohannon is a researcher and author with a Ph.D. from Columbia University in the evolution of narrative and cognition. Her essays and poems have appeared in Scientific American, Mind, Science Magazine, The Best American Nonrequired Reading, The Georgia Review, The Story Collider, and Poets Against the War. She lives with her family in Seattle. Bonnie Garmus is a copywriter and creative director who has worked widely in the fields of technology, medicine, and education. She’s an open-water swimmer, a rower, and mother to two pretty amazing daughters. Born in California and most recently from Seattle, she currently lives in London with her husband and her dog, 99.

220. Jim Al-Khalili: The Joy of Thinking and Living Scientifically
Today’s information (and misinformation) overload is difficult and confusing to navigate. Post-truth politics and conspiracy theories abound. Science and scientists are under growing suspicion, causing even more confusion and unrest. At the same time, we need science to survive today’s biggest threats like pandemics and climate change. To bridge this gap, acclaimed physicist and New York Times bestselling author Jim Al-Khalili wants us all to start thinking like scientists. Al-Khalili believes that the practice of science can offer us a way of thinking and understanding our complex world. He’s created a guide to leading a more rational life, inviting people to engage with the world as scientists have been trained to do. He defines the “how” and “why” behind science, as well as what science is (and what it’s not). With today’s scrutiny over science, Al-Khalili admits that scientists need to do more to communicate how they work to build trust and credibility in the public eye. One way to do that is for everyone to adopt the scientific method in our daily lives. Science may not only solve today’s biggest problems, but it can be a way for everyone to make everyday decisions for themselves and their loved ones. Jim Al-Khalili is an Iraqi-born theoretical physicist at the University of Surrey, where he holds a Distinguished Chair in physics as well as a university chair in public engagement in science. He has written 14 books on popular science and the history of science, between them translated into twenty-six languages. His latest books include The Joy of Science and The World According to Physics, which was shortlisted for the Royal Society Book Prize. He is a regular presenter of TV science documentaries, such as the Bafta-nominated Chemistry: A Volatile History and he hosts the long-running weekly BBC Radio 4 program, The Life Scientific.
