199. Derek Sheffield, CMarie Fuhrman, and Elizabeth Bradfield - Defining Cascadia: A Cultural Celebration
What comes to mind when you think of the Pacific Northwest? You might think of land forms like the Cascade Mountains, Olympic Peninsula, and the Willamette Valley, or of the Coast Salish and other Indigenous peoples who lived here since time immemorial. Or perhaps you’d think of urban centers like Vancouver, Seattle, or Portland, and the city-dwellers who call them home. And don’t forget the iconic flora and fauna that live and grow here –– lush ferns and mosses, huckleberries, salmon, orcas, and the mountain beaver. These, and so much more, define our region as a unique and special place found nowhere else on earth. This is Cascadia, stretching from Southeast Alaska to Northern California and from the Pacific Ocean to the Continental Divide. In a collection of art, poetry, and stories just as diverse as the region itself, the Cascadia Field Guide brings together scientific, sensory, and cultural knowledge to celebrate this unique corner of North America. Editors Derek Sheffield, CMarie Fuhrman, and Elizabeth Bradfield bring together dozens of authors and artists to describe 13 communities (from Tidewater Glacier to Shrub-Steppe) and 128 beings (from cryptobiotic soil to the giant Pacific octopus) that fill Cascadia with wonder. Ranging from comic to serious, colloquial to scientific, urban to off-the-grid, and narrative to postmodern, the Cascadia Field Guide offers any reader, local or visitor, a new way of connecting -– with heart and mind and body -– to place. Derek Sheffield grew up in the Willamette Valley and on the shores of the Salish Sea. He is the author of four books, including Not for Luck, winner of the Wheelbarrow Books Poetry Prize, and his poems have appeared in High Country News, Poetry, and Orion. For the past 20 years, he has taught nature writing at Wenatchee Valley College. The poetry editor of Terrain.org, he lives with his family near Leavenworth, Washington. CMarie Fuhrman is the author of Camped Beneath the Dam and her writing has appeared in many journals and anthologies. Fuhrman is the Director of Poetry for Western Colorado University’s MFA in Creative Writing Program where she also teaches nature writing. She lives in West Central Idaho with her partner, Caleb, and their dogs, Carhartt and Cisco. Elizabeth Bradfield is the author of five books, and her poems have appeared in The New Yorker, Poetry, The Atlantic Monthly, Orion, and elsewhere. A Stegner Fellow and Audre Lorde Prize winner, she is the founder of Broadsided Press, teaches at Brandeis University, and has worked as a naturalist in Cascadia and beyond for the past twenty-some years. Bradfield grew up in Tacoma and attended the University of Washington; she lives on Cape Cod. The Cascadia Field Guide Mountaineers Books

198. Katie Davis - The Role of Digital Media in the Ages and Stages of Growing Up
Children are encountering technology at younger and younger ages, which leads many parents to ask: how do children engage with technology at each stage of development and how can they best be supported? From toddlers who are exploring their immediate environment, to twentysomethings who are exploring their place in society, technology inevitably and profoundly affects human development. What happens to the little ones, the tweens, and the teenagers when technology — ubiquitous in the world they inhabit — becomes a critical part of their lives? Katie Davis, Associate Professor at the UW Information School, brings much-needed clarity to what we know about technology’s role in child development, as well as guidance for how to help children of all ages make the most of their digital experiences. In her new book Technology’s Child, Davis draws on her expertise in developmental science and design research to describe what happens when child development and technology design interact, and how this interaction is complicated by children’s individual characteristics and social and cultural contexts. Critically, she explains how a self-directed experience of technology — one initiated, sustained, and ended voluntarily — supports healthy child development, especially when it takes place within the context of community support. Children’s experiences with technology — their “screen time” and digital social relationships — have become an inescapable aspect of growing up. Davis identifies the distinctions between different ages and stages and how they engage with technology, offering invaluable guidance for parents and teachers navigating the digital landscape, and for technology designers charting the way. Katie Davis is an Associate Professor at the University of Washington Information School, where she is a founding member and Co-Director of the UW Digital Youth Lab. She is the co-author of The App Generation: How Today’s Youth Navigate Identity, Intimacy, Imagination in a Digital World (with Howard Gardner) and Writers in the Secret Garden: Fanfiction, Youth, and New Forms of Mentoring (with Cecilia Aragon).

196. Christopher J. Preston - Tenacious Beasts
The news about wildlife is dire — more than 900 species have been wiped off the planet since industrialization. Against this bleak backdrop, however, there are also glimmers of hope and crucial lessons to be learned from animals that have defied global trends toward extinction. Bear in Italy, bison in North America, whales in the Atlantic. These populations are back from the brink, some of them in numbers unimaginable in a century. How has this happened? What shifts in thinking did it demand? Drawing on compelling personal stories from the researchers, Indigenous people, and activists who know the creatures best, writer and professor Christopher Preston weaves together a gripping narrative of how some species are taking back vital, ecological roles. Observing different landscapes — farms, prairies, rivers, forests, oceans — Preston offers a philosophical shift in how humans ought to think about animals, passionately advocating for the changes in attitude necessary for wildlife recovery. Tenacious Beasts touches on different facets of ecological restoration from Indigenous knowledge to rewilding practices, and offers a road map — and a measure of hope — for a future in which humans and animals can once again coexist. Christopher J. Preston is a writer and professor based in Missoula, MT. His work at the University of Montana centers on wildlife, technology, and climate change. His new book, Tenacious Beasts: Wildlife Recoveries That Change How We Think About Animals investigates a number of species back from the brink of extinction. He meets the scientists, indigenous leaders, and activists responsible for their return and uncovers what these tenacious species have to teach. Christopher has written for The Atlantic, Smithsonian Magazine, Discover, The Conversation, Aeon, Slate.com, and the BBC. His award-winning book, The Synthetic Age: Outdesigning Evolution, Resurrecting Species, and Reengineering Our World, has been translated into six languages. He also gives talks in state parks, libraries, and breweries across Montana to campers and other audiences interested in conservation and technology. In early 2023, he won an annual award from the International Society for Environmental Ethics for his work as a public philosopher. Tenacious Beasts Third Place Books

195. David B. Auerbach - Automation vs. Humanity
Are the autonomous digital forces jolting our lives – as uncontrollable as the weather and plate tectonics – transforming life, society, culture, and politics? David Auerbach’s exploration of the phenomenon he has identified as the meganet begins with a simple, startling revelation: There is no hand on the tiller of some of the largest global digital forces that influence our daily lives: from corporate sites such as Facebook, Amazon, Google, YouTube, Instagram, and Reddit to the burgeoning metaverse encompassing cryptocurrencies and online gaming to government systems such as China’s Social Credit System and India’s Aadhaar. As we increasingly integrate our society, culture, and politics within a hyper-networked fabric, Auerbach explains how the interactions of billions of people with unfathomably large online networks have produced a new sort of beast: ever-changing systems that operate beyond the control of the individuals, companies, and governments that created them. Meganets, Auerbach explains, have a life of their own. Actively resisting attempts to control them, they can produce spontaneous, unexpected social groups and uprisings that could not have even existed twenty years ago. Constantly modifying themselves in response to user behavior, which can result in collectively authored algorithms no one can control, these enormous invisible organisms seem to be the new minds of the world, increasingly commandeering our daily lives and inner realities. David B. Auerbach is a writer, technologist, and software engineer who worked at Google and Microsoft after graduating from Yale University. His writing has appeared in the Times Literary Supplement, MIT Technology Review, The Nation, n+1, Tablet, The Daily Beast, and Bookforum, among many other publications. He was Slate’s technology columnist from 2013 to 2016, and he was nominated for a National Magazine Award for his coverage of the HealthCare.gov hearings. He teaches the history of computation at the New Centre for Research and Practice and is a frequent guest at their events. He has lectured around the world on technology, literature, and philosophy and, in addition, has done scholarly research on James Joyce, William Shakespeare, and artificial intelligence. His first book, Bitwise: A Life in Code, was published by Pantheon in 2018. Meganets Third Place Books

194. Barbara Rae-Venter - Cracking the Case of the Golden State Killer
For twelve years the Golden State Killer terrorized California, stalking victims and killing without remorse. Then he simply disappeared, for the next forty-four years, until an amateur DNA sleuth opened her laptop. In I Know Who You Are, Barbara Rae-Venter reveals how she went from researching her family history as a retiree to hunting for a notorious serial killer — and how she became the nation’s leading authority on investigative genetic genealogy, the most dazzling new crime-fighting weapon to appear in decades. Rae-Venter, leads readers on a vivid journey through the many cases she tackled, often starting with little more than a DNA sample. From the first criminal case she ever solved— uncovering the long-lost identity of a child abductee — to the heartbreaking story of the Billboard Boy, whose skeletal remains were discovered along a highway, to the search for the Golden State Killer, Rae-Venter shares accounts of how she helped solve some of America’s most chilling cold cases in the span of just three years. Rae-Venter’s story is one of relentless curiosity, of constant invention and reinvention, and of human beings striving to answer the most elemental questions about themselves: What defines identity? Where do we belong? And are we truly who we think we are? Barbara Rae-Venter will be in conversation with Steve Broback for this event. Barbara Rae-Venter is a New Zealand–born American investigative genetic genealogist, biochemist, and retired patent attorney best known for her work helping the FBI and other investigators identify Joseph James DeAngelo as the Golden State Killer.

191. Orly Lobel with Beverly Aarons: Greater Humanity through Greater Technology
How much does the general public really trust tech? Despite increased scrutiny and critique of digital platforms, renowned tech policy scholar Orly Lobel defends digital technology, including AI, as a powerful tool we can harness to achieve equality and a better future. Lobel recognizes the criticism of big data and automation, and she does not refute the many challenges that technology presents — but at the same time, Lobel encourages us to improve it. We cannot stop technological development, Lobel argues, but we can direct its course according to our most fundamental values. In The Equality Machine: Harnessing Digital Technology for a Brighter, More Inclusive Future, Lobel presents evidence that digital technology frequently has a comparative advantage over humans in detecting discrimination, correcting historical exclusions, subverting long-standing stereotypes, and addressing some of the world’s complex problems: climate, poverty, injustice, literacy, accessibility, speech, health, and safety. Lobel offers insights in each chapter that tackle everything from labor markets to dating markets, revealing just how much of our lives can be changed — and in her view, improved — via technology. Through analysis and storytelling, The Equality Machine promises to add to the robust, ongoing debate about technology and serves as a call to restore human agency over our own values. Orly Lobel is the Warren Distinguished Professor of Law and Director of the Center for Employment and Labor Policy at the University of San Diego.

192. Eric H. Chudler: The Human Brain from A to Z
The brain has fascinated scientists and philosophers alike for thousands of years. What’s really going on up there? Just ask neuroscientist, Eric H. Chudler. As the executive director of the Center for Neurotechnology at the University of Washington in Seattle, Chudler is poised to help you get to know your brain. His latest book on the subject, Neuropedia: A Brief Compendium of Brain Phenomena, is less of a textbook and more of a beautifully illustrated, alphabetic meandering through all things brain. Through his cataloging of concepts and the people working in neuroscience, Chudler journeys into the mysteries and marvels of the enigmatic three pounds of tissue between your ears. He’s developed a new kind of tour of the nervous system that explores the structure and function of the brain and covers topics such as the spinal cord and nerve cells, methods of neuroscientific research, and the visionary scientists who have dedicated their lives to understanding what makes each of us who we are. Chudler also guides readers through a variety of rare and common neurological disorders such as alien hand disorder, Capgras syndrome, Alzheimer’s disease, Parkinson’s disease, and stroke, and discusses the latest brain-imaging methods used to diagnose them. While we know a lot more about the brain than we did in centuries past, it still holds plenty of mystery. Chudler’s accessible approach helps put into context our current understanding of neuroscience, while also providing a glimpse into where it’s headed in the future. Chudler aims to stimulate your curiosity about your own brain and follow in the footsteps of the scientists and philosophers throughout the ages — by continuing to learn more. Eric H. Chudler is executive director of the Center for Neurotechnology and a neuroscientist at the University of Washington in Seattle. His books include Brain Bytes: Quick Answers to Quirky Questions about the Brain and The Little Book of Neuroscience Haiku.

190. Karen Bakker with Sally James: Uncovering the Secret Sounds of Life
Have you ever wished that animals or plants could talk to us? As it turns out, they can. The natural world is teeming with conversation, though many of it is beyond human hearing range. Scientists are using groundbreaking digital technologies to uncover these sounds, revealing vibrant communication in the Tree of Life. In The Sounds of Life: How Digital Technology Is Bringing Us Closer to the Worlds of Animals and Plants, Karen Bakker, Professor and director of the Program on Water Governance at the University of British Columbia, shares fascinating stories of nonhuman sound, interweaving insights from technological innovation and traditional knowledge: We learn how artificial intelligence can decode these sounds, and meet the researchers building dictionaries in East African Elephant and Sperm Whalish. We explore digitally mediated dialogues with bats and honeybees. We are introduced to the innovative minds who are using sound to protect and regenerate endangered species from the Great Barrier Reef to the Arctic and the Amazon. We are presented with shocking facts regarding the impact of noise pollution on both animals and plants. At a time where the natural and tech worlds are often presented as mutually exclusive, Dr. Bakker’s book challenges that idea, calling upon interdisciplinary research that reveals more about the interconnectedness of it all and advising us to listen, not just look. After this talk, you may never see outdoor adventures the same way again.
