The Michael Shermer Show is a series of long-form conversations between Dr. Michael Shermer and leading scientists, philosophers, historians, scholars, writers and thinkers about the most important issues of our time.

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the 20-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics.

On the morning of December 26, 2004, on the southern coast of Sri Lanka, Sonali Deraniyagala lost her parents, her husband, and her two young sons in the tsunami she miraculously survived. In this brave and searingly frank memoir, she describes those first horrifying moments and her long journey since. She has written an engrossing, unsentimental, beautifully poised account: as she struggles through the first months following the tragedy, furiously clenched against a reality that she cannot face and cannot deny....

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

A farm kid at heart, and a Nlaka'pamux woman of mixed ancestry, Dr. Jennifer Grenz always felt a deep connection to the land. Which is why, after nearly two decades of working as a restoration ecologist in the Pacific Northwest, she became frustrated that she and her colleagues weren't making the meaningful change needed for plant, animal and human communities to adapt to a warming climate. She began to question the central conceit of restoration ecology: that somehow, we must return the natural world to an untouched, pristine state, placing humans in a godlike role.

Remarkable new discoveries affirm the octopus as one of nature’s most intelligent and complex animals. This new book brings us closer than ever to these elusive creatures. The companion to the highly anticipated National Geographic television special, this book explores the alluring underwater world of the octopus—a creature that resembles an alien lifeform, but whose behavior has earned it a reputation as one of the most intelligent animals on the planet.

In the 21st century, humanity is reaching new heights of scientific understanding - and at the same time appears to be losing its mind. How can a species that developed vaccines for COVID-19 in less than a year produce so much fake news, medical quackery, and conspiracy theorizing? Pinker rejects the cynical cliché that humans are an irrational species - cavemen out of time saddled with biases, fallacies, and illusions.

Astrophysicist J. Craig Wheeler, former president of the American Astronomical Society, takes a critical look at the technological advances shaping our future. From artificial intelligence to genetic engineering, Wheeler explores how these innovations are interconnected and the potential they hold for humanity's evolution. With thought-provoking insights into the ethical dilemmas we face, Wheeler stresses the importance of staying informed and proactive.

The extraordinary Siddhartha Mukherjee has written a biography of the gene as deft, brilliant, and illuminating as his extraordinarily successful biography of cancer. Weaving science, social history, and personal narrative to tell us the story of one of the most important conceptual breakthroughs of modern times, Mukherjee animates the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices.

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Old or unsuitable motorbikes, distant places, poor weather, and gravel roads, these are the common threads in Nick’s motorcycle travels. He’d been hoping to ride out west a couple of years ago until a little heart trouble intervened. Two years later, a short "shake-down" trip morphed into a 9000 mile journey across the continent. Trouble free? Not exactly. Riding a 1972 Moto Guzzi Eldorado, a Suzuki Burgman Scooter, and a 1976 Moto Guzzi Convert (automatic), and ever optimistic, Nick heads for the Canada’s distant horizons.

A century ago very few people dreamed of space travel. Today it is the most daring and technologically sophisticated quest ever undertaken, being driven not just by government agencies such as NASA and ESA, but also by visionaries such as Richard Branson (Virgin Galactic), Elon Musk (SpaceX) and Jeff Bezos (Blue Origin). To mark the 50th anniversary of the 1969 moon landing, this major drama-documentary series charts the definitive story of the past, present and future of humankind’s exploration of space. The Space Race is narrated by Kate Mulgrew and features a full cast.

Over thousands of years, the Mississippi watershed was home to millions of Indigenous people who regarded "the great river" with awe and respect, adorning its banks with astonishing spiritual earthworks. But European settlers and American pioneers had a different vision: the river was a foe to conquer. In this landmark work of natural history, Boyce Upholt tells the epic story of human attempts to own and contain the Mississippi River, from Thomas Jefferson's expansionist land hunger through today's era of environmental concern

How does the brain—a three-pound wrinkly mass—give rise to intelligence and conscious experience? Was Freud right that we are all plagued by forbidden sexual desires? What is the function of emotions such as disgust, gratitude, and shame? Renowned psychologist Paul Bloom answers these questions and many more in Psych, his riveting new book about the science of the mind.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

This mind-bending tour of metaphysics applies philosophy to the forefront of today's knowledge. Over the course of 24 fascinating lectures, Professor Johnson thinks through the big questions about humans and the universe: The relationship between the mind and the brain, how consciousness emerges from neurochemical processes, the existence of God, human free will, the possibility of time travel, and whether we live in a multiverse or even a computer simulation.

According to the prevailing scientific paradigm, the universe tends toward randomness; it functions according to laws without purpose, and life is an accident devoid of meaning. Thanks to a new understanding of evolution, as well as recent advances in our understanding of the phenomenon known as emergence, a new cosmic narrative is taking shape: Nature’s simplest “parts” come together to form ever-greater “wholes” in a process that has no end in sight. Bobby Azarian explains the science behind this new view of reality and explores what it means for all of us.

The United States spends an excess $1.5 trillion annually on health care compared to other wealthy countries—yet the amount of time that Americans live in good health ranks a lowly 68th in the world. At the heart of the problem is Big Pharma, which funds most clinical trials and therefore controls the research agenda, withholds the real data from those trials as corporate secrets, and shapes most of the information relied upon by health care professionals.
