Charles Watkins joins Jana Byars to talk about his new book, Trees Ancient and Modern (Reaktion, 2025). This delightful new book explores the relationship between trees and people and reveals how people have used, valued and understood forests over time. While trees are celebrated as symbols of natural beauty, they are increasingly at risk from climate change, disease, fires and urban expansion. Trees Ancient and Modern explores humanity’s deep connection with trees and woodlands, highlighting their beauty and importance and the challenges they face. The book looks at debates about creating new woodlands, exploring questions of location, ownership and management.Using diverse sources such as literature, art, historical records, scientific surveys and oral histories, Charles Watkins reveals how people have used, valued and understood forests over time. He also assesses modern threats to woodlands and considers how best to conserve them. Richly illustrated, this is a global social and cultural history of forests that provides valuable insights for future management. Learn more about your ad choices. Visit megaphone.fm/adchoices

Rigby’s Encyclopaedia of the Herring: Adventures with the King of Fishes (Hurst, 2025) by Graeme Rigby contains almost everything you didn’t know you needed to know about Atlantic herrings. (Pacific and Baltic varieties are in there too.) Herrings make the world bigger: with spawnings seen from space, a trillion individuals make this one of the tastiest and most abundant vertebrates on Earth. From ‘A Beginning’ to ‘Zuiderzee’, count the wars fought over herrings; don’t forget Scotland vs the Holy Roman Empire. The herring’s high-pitched farts were logged as Soviet submarines, and one herring joke featured in a Jonson play, four Shakespeare plays and the glorious, suppressed fantasia Nashes Lenten Stuffe. Herrings mock taxonomists; physically change with sea temperature and salinity; stuff predators full to bursting, then swim away. The Great Sardine Litigation? The true history of kippers? Bloaters? Reds? Chopped herring? Shuba? All this and more. Between sustainable fishery genetics, sixteenth-century Bavaria’s ‘Herrings, herrings, stinking herrings’, and Van Gogh’s ear, every entry is a story, a comic journey, an adventure. Some even come with recipes. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

What's the secret to keeping your balance? The ear does more than hear: it helps us stay stable by perceiving movements and gravity. Elegant sensors deep within the skull detect every twist, turn, and tumble, powering swift reflexes that keep vision and balance steady. This is the vestibular system. It's primordial and ubiquitous: every animal has one, and even plants have a rudimentary version. It works so well that we take it for granted--until it fails. How does this remarkable system function? What happens when it goes haywire? How can modern medicine treat vestibular disease? The Great Balancing Act: An Insider's Guide to the Human Vestibular System (Columbia UP, 2025) tells the story of the vestibular system, from T. rex hearing organs to cochlear implants, and from the unsung power of hair cells to inner-ear problems in outer space. Combining neuroscience, history, and medicine, Jeffrey D. Sharon--a vestibular doctor and researcher--explains the sense of balance using accessible language and wry humor. He recounts how pioneering scientists solved the mysteries of the vestibular system and shows why it is necessary for spatial reasoning and abstract thought. Sharon explores the devastating consequences of vestibular problems such as vertigo, dizziness, and imbalance, offering an expert, patient-friendly look at emerging and future treatments. Engaging and entertaining, this book invites readers to discover a little-known yet vital part of ourselves. Learn more about your ad choices. Visit megaphone.fm/adchoices

A leading astrobiologist "demonstrates how becoming a true space-faring species is more than just humanity's future" (Adam Frank, author of The Little Book of Aliens)--it is an evolutionary event at least as important as life's first journey from sea to land The story of life has always been one of great transitions, of crossing new frontiers. The dawn of life itself is one; so, too, is the first time two cells stuck together rather than drifting apart. And perhaps most dramatic were the moves from the sea to land, land to air. Each transition has witnessed wild storms of innovation, opportunity, and hazard. It might seem that there are no more realms for life to venture. But there is one: space. In The Giant Leap: Why Space Is the Next Frontier in the Evolution of Life (Hachette UK, 2025), astrobiologist Caleb Scharf argues that our journey into space isn't simply a giant leap for humankind--it's life's next great transition, an evolution of evolution itself. Humans and our technology are catalysts for an interplanetary transformation, marking a disruption in the story of life as fundamental as life's movement from sea to land, and land to sky. Inspired by Darwin's account of his journey on the Beagle, and packed with stories from the past, present, and future of space travel, The Giant Leap thrills at both life's creativity and the marvels of technology that have propelled us into the cosmos. And it offers an awesome glimpse of the grander vistas that wait in the great beyond. Learn more about your ad choices. Visit megaphone.fm/adchoices

The story behind Dr. Gerta Keller’s world-shattering scientific discovery that dinosaur extinction was NOT caused by asteroid impact, but rather by volcanic eruptions on the Indian peninsula, a discovery that highlights today’s existential threat of greenhouse gasses and climate change—and one that sparked an all-out war waged by the scientific establishment.Part scientific detective story, part personal odyssey, The Last Extinction: The Real Science Behind the Death of the Dinosaurs (Diversion Books, 2025) is the definitive account of a radical theory that has reshaped how we understand our planet’s past and, as we face the possibility of a sixth extinction, how we might survive its future.For decades, the dominant theory held that an asteroid impact caused the dinosaurs’ extinction. But Princeton Geologist Dr. Gerta Keller followed the evidence to the truth: Deccan volcanism, a series of massive volcanic eruptions in India, triggered a long-term climate catastrophe and Earth’s fifth mass extinction. Her findings upended the field and ignited a bitter feud in modern science—what became known as the “Dinosaur Wars.”Raised in poverty on a Swiss farm and told she could never be a scientist, Keller defied expectations, earning her PhD at Stanford and battling her way into the highest ranks of Geology, eventually becoming a Professor of Paleontology and Geology at Princeton University. Her refusal to back down in the face of ridicule, sabotage, and sexism makes her story as thrilling as her science, which offers urgent insight into today’s climate crisis: Sustained planetary upheaval—not a single cataclysmic event—can plunge the planet into an age of death.

How the science of evolution explains how everything came to be, from bacteria and blue whales to cell phones, cities, and artificial intelligence Everything Evolves: Why Evolution Explains More Than We Think, from Proteins to Politics (Princeton UP, 2025) reveals how evolutionary dynamics shape the world as we know it and how we are harnessing the principles of evolution in pursuit of many goals, such as increasing the global food supply and creating artificial intelligence capable of evolving its own solutions to thorny problems. Taking readers on an astonishing journey, Mark Vellend describes how all observable phenomena in the universe can be understood through two sciences. The first is physics. The second is the science of evolvable systems. Vellend shows how this Second Science unifies biology and culture and how evolution gives rise to everything from viruses and giraffes to nation-states, technology, and us. He discusses how the idea of evolution had precedents in areas such as language and economics long before it was made famous by Darwin, and how only by freeing ourselves of the notion that the study of evolution must start with biology can we appreciate the true breadth of evolutionary processes. A sweeping tour of the natural and social sciences, Everything Evolves is an essential introduction to one of the two key pillars to the scientific enterprise and an indispensable guide to understanding some of the most difficult challenges of the Anthropocene.

Humans live in richly normatively structured social environments: there are ways of doing things that are appropriate, and we are aware of what these ways are. For many social scientists, social institutions are sets of rules about how to act, though theories differ about what the rules are, how they are established and maintained, and what makes some social institutions stable through social change and others more transient. In Presentist Social Functionalism: Bringing Contemporary Evolutionary Biology to the Social Sciences (Springer, 2025), Armin Schulz defends a version of the general view that social institutions have functions, drawing on a concept of function from evolutionary biology. On his view, the function of a social institution is not a matter of its history, but those features that explain its ability to survive and thrive in the here and now. Schulz, who is professor of philosophy at the University of Kansas, also uses this account to provide an explanation of what institutional corruption amounts to, and to analyze current debates between shareholder vs. stakeholder views of the function of a corporation.

Inside our heads we carry around an infinite and endlessly unfolding map of the world. Navigation is one of the most ancient neural abilities we have―older than language. In Dark and Magical Places: The Neuroscience of Navigation (Norton, 2022), Christopher Kemp embarks on a journey to discover the remarkable extent of what our minds can do. Fueled by his own spatial shortcomings, Kemp describes the brain regions that orient us in space and the specialized neurons that do it. Place cells. Grid cells. He examines how the brain plans routes, recognizes landmarks, and makes sure we leave a room through a door instead of trying to leave through a painting. From the secrets of supernavigators like the indigenous hunters of the Bolivian rainforest to the confusing environments inhabited by people with place blindness, Kemp charts the myriad ways in which we find our way and explains the cutting-edge neuroscience behind them. How did Neanderthals navigate? Why do even seasoned hikers stray from the trail? What spatial skills do we inherit from our parents? How can smartphones and our reliance on GPS devices impact our brains? In engaging, engrossing language, Kemp unravels the mysteries of navigating and links the brain’s complex functions to the effects that diseases like Alzheimer’s, types of amnesia, and traumatic brain injuries have on our perception of the world around us. A book for anyone who has ever felt compelled to venture off the beaten path, Dark and Magical Places is a stirring reminder of the beauty in losing yourself to your surroundings. And the beauty in understanding how our brains can guide us home.

For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists. Charles Darwin speculated about life on Earth beginning in a warm little pond. Some of his contemporaries believed that life existed on Mars. It once seemed inevitable that the truth would be known by now. It is not. For more than a century, the origins and extent of life have remained shrouded in mystery. But, as Mario Livio and Jack Szostak reveal in Is Earth Exceptional?: The Quest for Cosmic Life (Basic Books, 2024), the veil is finally lifting. The authors describe how life's building blocks--from RNA to amino acids and cells--could have emerged from the chaos of Earth's early existence. They then apply the knowledge gathered from cutting-edge research across the sciences to the search for life in the cosmos: both life as we know it and life as we don't. Why and where life exists are two of the biggest unsolved problems in science. Is Earth Exceptional? is the ultimate exploration of the question of whether life is a freak accident or a chemical imperative.

Octopuses can open jars to get food, and chimpanzees can plan for the future. An IBM computer named Watson won on Jeopardy! and Alexa knows our favorite songs. But do animals and smart machines really have intelligence comparable to that of humans? In Bots and Beasts: What Makes Machines, Animals, and People Smart? (MIT Press, 2021), Paul Thagard looks at how computers (“bots”) and animals measure up to the minds of people, offering the first systematic comparison of intelligence across machines, animals, and humans. Thagard explains that human intelligence is more than IQ and encompasses such features as problem solving, decision making, and creativity. He uses a checklist of twenty characteristics of human intelligence to evaluate the smartest machines—including Watson, AlphaZero, virtual assistants, and self-driving cars—and the most intelligent animals—including octopuses, dogs, dolphins, bees, and chimpanzees. Neither a romantic enthusiast for nonhuman intelligence nor a skeptical killjoy, Thagard offers a clear assessment. He discusses hotly debated issues about animal intelligence concerning bacterial consciousness, fish pain, and dog jealousy. He evaluates the plausibility of achieving human-level artificial intelligence and considers ethical and policy issues. A full appreciation of human minds reveals that current bots and beasts fall far short of human capabilities.

When we think of the forces driving cancer, we don’t necessarily think of evolution. But evolution and cancer are closely linked because the historical processes that created life also created cancer. The Cheating Cell: How Evolution Helps Us Understand and Treat Cancer (Princeton UP, 2020) delves into this extraordinary relationship, and shows that by understanding cancer’s evolutionary origins, researchers can come up with more effective, revolutionary treatments. Athena Aktipis goes back billions of years to explore when unicellular forms became multicellular organisms. Within these bodies of cooperating cells, cheating ones arose, overusing resources and replicating out of control, giving rise to cancer. Aktipis illustrates how evolution has paved the way for cancer’s ubiquity, and why it will exist as long as multicellular life does. Even so, she argues, this doesn’t mean we should give up on treating cancer—in fact, evolutionary approaches offer new and promising options for the disease’s prevention and treatments that aim at long-term management rather than simple eradication. Looking across species—from sponges and cacti to dogs and elephants—we are discovering new mechanisms of tumor suppression and the many ways that multicellular life-forms have evolved to keep cancer under control. By accepting that cancer is a part of our biological past, present, and future—and that we cannot win a war against evolution—treatments can become smarter, more strategic, and more humane. Unifying the latest research from biology, ecology, medicine, and social science, The Cheating Cell challenges us to rethink cancer’s fundamental nature and our relationship to it.

Are zoos an anachronism in the 21st century when we can watch animals in their natural habitat, close-up from our couches without worrying about cruelty? Should they go the way of other bygone era ‘spectacles’ and ‘attractions’ that we now regard as barbaric? There are vocal campaigners and activists who believe so. Heather Browning and Walter Veit disagree, but they acknowledge there is a case to be answered. In What Are Zoos For? (Bristol University Press, 2024) they test the common justifications for zoos (entertainment, education, research, conservation) against the evidence and suggest what the best zoos of the future should look like to ensure that they are primarily for animals and not just for people. Heather Browning is Lecturer in Philosophy at the University of Southampton. Her primary research interests are animal welfare, ethics, and consciousness. Previously, she worked for many years as a zookeeper and zoo animal welfare officer, interested in the practical application of animal welfare measurement. Walter Veit is Lecturer in Philosophy at the University of Reading and an external member of the Munich Center for Mathematical Philosophy, Ludwig Maximilian University of Munich. He’s also the author of A Philosophy for the Science of Animal Consciousness (Routledge, 2023). Most of his ongoing research is on the consciousness and welfare of animals and AIs.

When Christa Kuljian arrived on the Harvard College campus as a first-year student in the fall of 1980 with copies of Our Bodies, Ourselves and Ms. magazine, she was concerned that the women's movement had peaked in the previous decade. She soon learned, however, that there was a long way to go in terms of achieving equality for women and that social movements would continue to be a critical force in society. She began researching the history of science and gender biases in science, and how they intersect with race, class, and sexuality. In Our Science, Ourselves: How Gender, Race, and Social Movements Shaped the Study of Science (University of Massachusetts Press, 2024), Kuljian tells the origin story of feminist science studies by focusing on the life histories of six key figures--Ruth Hubbard, Rita Arditti, Evelyn Fox Keller, Evelynn Hammonds, Anne Fausto-Sterling, and Banu Subramaniam. These women were part of a trailblazing network of female scientists in the 1970s, 80s, and 90s who were drawn to the Boston area--to Harvard, MIT, and other universities--to study science, to network with other scientists, or to take a job. Inspired by the social and political activism of the women's movement and organizations such as Science for the People, the Genes and Gender Collective, and the Combahee River Collective, they began to write and teach about women in science, gender and science, and sexist and racist bias and exclusion. They would lead the critiques of E. O. Wilson's sociobiology in 1975 and Larry Summers' comments about women in science thirty years later. Drawing on a rich array of sources that combines published journal articles and books with archival materials and interviews with major luminaries of feminist science studies, Kuljian chronicles and celebrates the contributions that these women have made to our collective scientific knowledge and view of the world. Christa Kuljian grew up in the Boston area, and has lived in Johannesburg, South Africa for the past thirty years. She is a science writer and the author of Sanctuary and Darwin's Hunch: Science, Race and the Search for Human Origins, which was short listed for the Sunday Times Alan Paton Award for Non-Fiction. Currently a Research Associate at the Wits Institute for Social and Economic Research (WiSER) at Wits University, she is also a fellow with the Consortium for History of Science, Medicine and Technology (CHSMT) in Philadelphia.

How has evolutionary theory shaped educational thinking over the past two centuries? ‘Evolutionary Theory and Education: The Influence of Evolutionary Thinking on Educational Theory and Philosophy’ (Brill, 2025) explores the considerable but under-appreciated influence of evolutionary ideas on educational theory and the philosophy of education. The book reveals the interplay between educational and evolutionary perspectives along the concepts of ‘adaptation’, ‘selection’, ‘inheritance’, and ‘progress’. It tracks these ideas across the works of various influential educational thinkers, including Herbert Spencer, Jean Piaget, John Dewey and Lev Vygotsky, and examines their continuing significance for how we understand and practice education today.

In Seminal: On Sperm, Health, and Politics, Rene Almeling, Lisa Campo-Engelstein, and Brian T. Nguyen come together across disciplines to offer a kaleidoscopic view of the relationship between sperm, health, and the intersecting politics of gender, race, and reproduction. Always insightful and often provocative, the essays in this unprecedented collection cover a broad range of issues related to male reproductive and sexual health—including the latest technological developments for creating sperm; the specter of eugenics in contemporary medical markets; emerging approaches to male contraceptive methods, male infertility, and trans healthcare; controversies surrounding sperm donors and sperm banking; disparities in sexual health education for teens—all the while attending to the enormous variation in how individuals and societies understand, embody, and experience sperm. At a time when the most basic rights of reproductive autonomy are under severe threat, contributors to this volume argue this is precisely the moment to rethink and reimagine sperm from a variety of medical, political, and cultural perspectives. Ultimately, this volume aims to contribute to a more reproductively just society and broaden conversations around bodies, health and equity in the United States. Michael O. Johnston, Ph.D. is a Assistant Professor of Sociology at William Penn University.

The 15,000-year story of how grass seduced humanity into being its unwitting labor force--and the science behind it. Domesticated crops were not human creations, and agriculture was not simply invented. As Robert N. Spengler shows, domestication was the result of an evolutionary process in which people played a role only unwittingly and as actors in a numberless cast that spanned the plant and animal kingdoms. Nature's Greatest Success: How Plants Evolved to Exploit Humanity (Univ of California Press, 2025) is the first book to bring together recent scientific discoveries and fascinating ongoing research to provide a systematic account of not only how agriculture really developed but why. Through fifteen chapters, this book dives deep into the complex processes that drove domestication and the various roles that plants and animals, including humans, played in bringing about those changes. At the intersection of popular history, archaeology, and evolutionary biology, Nature's Greatest Success offers a revolutionary account of humanity not at the apex of nature but deeply embedded in the natural world and the evolutionary processes that continue to guide it even today.

The vagus nerve is fundamental to our health and vitality, coordinating critical functions from the precise heartbeat we need to exercise or rest to the balance of appetite and digestion. Made up of 200,000 fibers, the vagus nerve sends thousands of electrical signals every second between your brain and your most important organs. Yet despite its essential role in life, important vagus nerve functions have eluded centuries of scientific investigation. Now neurosurgeon and researcher Dr. Kevin Tracey has discovered the previously unknown power of the vagus nerve to reverse inflammation, balance the immune system, treat chronic illness, and keep our organs humming together in harmony.In The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes (Penguin, 2025), Dr. Tracey shows us how stimulating the vagus nerve with a tiny electrical implant has the potential to reverse life-altering diseases like rheumatoid arthritis, inflammatory bowel disease, lupus, MS, diabetes, obesity, stroke, depression, Alzheimer’s and Parkinson’s. If this sounds too good to believe, Dr. Tracey shares stories of patients who have gone from being nearly bedridden to running and dancing, along with the science that makes possible these recoveries. He also explains the evidence for lifestyle strategies like ice baths, meditation, exercise, and breathwork that can maintain and improve vagus nerve function.By opening the door to the new field of neuroimmunology, The Great Nerve  not only revolutionizes how we understand and treat disease, it gives us unprecedented hope for our health. This is the story of your body’s ability to heal itself. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

An awe-inspiring journey into the world of proteins--how they shape life, and their remarkable potential to heal our bodies and our planet. Each fall, a robin begins the long trek north from Gibraltar to her summer home in Central Europe. Nestled deep in her optic nerve, a tiny protein turns a lone electron into a compass, allowing her to see north in colors we can only dream of perceiving. Taking us beyond the confines of our own experiences, The Color of North: The Molecular Language of Proteins and the Future of Life (Belknap Press, 2025) traverses the kingdom of life to uncover the myriad ways that proteins shape us and all organisms on the planet. Inside every cell, a tight-knit community of millions of proteins skillfully contorts into unique shapes to give fireflies their ghostly glow, enable the octopus to see predators with its skin, and make humans fall in love. Collectively, proteins orchestrate the intricate relationships within ecosystems and forge the trajectory of life. And yet, nature has exploited just a fraction of their immense potential. Shahir S. Rizk and Maggie M. Fink show how breathtaking advances in protein engineering are expanding on nature's repertoire, introducing proteins that can detect environmental pollutants, capture carbon dioxide from the atmosphere, and treat diseases from cancer to COVID-19. Weaving together themes of memory, migration, and family with cutting-edge research, The Color of North unveils a molecular world in which proteins are the pulsing heart of life. Ultimately, we gain a new appreciation for our intimate connections to the world around us and a deeper understanding of ourselves. Learn more about your ad choices. Visit megaphone.fm/adchoices

What defines who we are? For decades, the answer has seemed obvious: our genes, the “blueprint of life.” In The Master Builder: How the New Science of the Cell Is Rewriting the Story of Life, biologist Alfonso Martinez Arias argues we’ve been missing the bigger picture. It’s not our genes that define who we are, but our cells. While genes are important, nothing in our DNA explains why the heart is on the left side of the body, how many fingers we have, or even how our cells manage to reproduce. Drawing on new research from his own lab and others, Martinez Arias reveals that we are composed of a thrillingly intricate, constantly moving symphony of cells. Both their long lineage—stretching back to the very first cell—and their intricate interactions within our bodies today make us who we are. Engaging and ambitious, The Master Builder will transform your understanding of our past, present, and future—as individuals and as a species. Learn more about your ad choices.
