More than a hundred salt lakes dot Earth's surface, most of them hidden away in remote desert valleys. But today nearly all of them are at risk of drying up. Their death is a harbinger of rising sea levels, life-threatening dust storms, and environmental collapse. Writer and geographer Caroline Tracey didn't know this when she began crossing paths with salt lakes during her early twenties. From the Great Salt Lake to the Aral Sea, across the American West and around the world, the unusual beauty of these shimmering, uncanny bodies of water captured her imagination.

When the government recently tried to abandon its responsibility to protect what little remains of the natural prairie, Trevor Herriot pushed back, only to discover an injustice haunting the lands he was trying to defend. In 1938, when the Métis of Ste. Madeleine returned from working away, they found their homes burnt to the ground and their animals shot. The land they held in common was no longer theirs, but was now controlled by the federal government.

All of us have lurking in our DNA a most remarkable gene, which has a crucial job – it protects us from cancer. Known simply as p53, this gene constantly scans our cells to ensure that they grow and divide without mishap. If a cell makes a mistake in copying its DNA during the process of division, p53 stops it in its tracks, summoning a repair team before allowing the cell to carry on dividing. If the mistake is irreparable and the rogue cell threatens to grow out of control, p53 commands the cell to commit suicide.

Ice is far more than frozen water—it is a force that shapes planets, preserves history, and hides some of nature’s strangest secrets. Hidden World of Ice takes you on a fascinating journey through the frozen corners of our world, uncovering the science, history, and bizarre wonders locked inside ice. From ancient glaciers that store Earth’s climate memory to the strange physics that makes ice behave unlike any other solid, this book reveals why frozen water is one of nature’s greatest mysteries.

Man nutzt es jeden Tag, jede Sekunde, und doch wissen die wenigsten, wie das Gehirn wirklich funktioniert. Dr. Jens Foell, renommierter Wissenschaftler und Wissenschaftskommunikator, entführt in die faszinierende Welt der Neuropsychologie und liefert praktische Ratschläge für den Alltag. Er erklärt, warum das Gehirn einen manchmal anlügt, beschreibt seine erstaunliche Plastizität (also die Fähigkeit, sich grundlegend zu verändern und zu heilen) und geht den Mechanismen nach, die Hoffnungslosigkeit auslösen. Dr.

Master general chemistry without the overwhelm. If you've ever felt lost in formulas, atomic theory, and reaction mechanisms that refuse to make sense, you're not alone. Most general chemistry textbooks pack in dense paragraphs and endless calculations—periodic trends blur with bonding theories, and you're rereading without learning.

What if topology were not about objects, but about transformations? Not about space, but about the conditions under which identity persists? This book invites listeners into a radical rethinking of mathematics—not as a solemn march of proofs, but as a living practice of imaginative stability, structural openness, and conceptual play. Moving through classical theory, unresolved conjectures, and emerging landscapes of abstraction, this work reframes topology as a mode of thought that thrives on deformation, ambiguity, and partial knowledge.

Nuclear energy stands at the crossroads of fear and necessity, science and public imagination, catastrophe and promise. This book offers a clear, penetrating examination of one of humanity’s most consequential technologies—its origins in cosmic processes, its role in the modern energy landscape, the accidents that shaped its reputation, and the profound ethical questions that surround its use. Rather than taking sides, it illuminates the hidden mechanisms, political pressures, psychological forces, and historical legacies that form the real structure of the nuclear debate.

Throughout the seventeenth century, medical lecturers demonstrated human anatomy by dissecting a cadaver while surrounded by students. After the Revolutionary War, though, instructors realized that they needed many more cadavers to serve a growing number of medical students. Enter the “resurrectionists”–body snatchers. Resurrectionists were a cruel lot; men (almost always men and often medical students themselves) who would sneak into a cemetery under the cover of darkness, remove a body, and then sell it to a physician or anatomist–usually for around $100.

The first human organ transplant in 1950 at a suburban hospital is the focus of The Graft: How a Pioneering Operation Sparked the Modern Age of Organ Transplants. The book examines the controversies the operation generated and the progress medicine has made in organ transplantation.

This work of narrative non-fiction deals with common questions and doubts people have about vaccines, using very accessible, conversational, non-technical language.

More mounds were built by ancient Native Americans in Wisconsin than in any other region of North America—between 15,000 and 20,000, at least 4,000 of which remain today. Most impressive are the effigy mounds, huge earthworks sculpted in the shapes of thunderbirds, water panthers, and other forms, not found anywhere else in the world in such concentrations. This second edition of Indian Mounds of Wisconsin is updated throughout, incorporating exciting new research and satellite imagery. Written for general listeners, it offers a comprehensive overview of these intriguing earthworks.

As we see the catastrophic effects of the Anthropocene proliferate, advanced technologies also grant us greater access to the furthest reaches of the world's oceans, facilitating the discovery of countless new species. Stacy Alaimo explores the influence this newfound intimacy with the deep sea might have on our broader relationship to the nonhuman world. While many images of these abyssal creatures circulate as shallow clickbait, aesthetic representations can be enticing lures for speculating about their lives.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.

Three hundred years ago, Leibniz proposed that our world is the "best of all possible worlds." Voltaire turned this idea into a joke. Philosophy moved on. The insight was lost. Until now.

Our solar system is a dynamic arena where asteroids careen off course and solar winds hurl charged particles across billions of miles of space. Yet we seldom consider how these events, so immense in scale, influence our fragile blue planet: Earth.

For most of human history, life offered no safety net. Environments shifted, resources vanished, and stability was always temporary. People lived on the move—carrying knowledge, forming bonds, and adapting to constant change. This audiobook examines how human life took shape long before familiar societies appeared. Drawing on archaeology, anthropology, and evolutionary science, it explores how early humans lived, moved, cooperated, and adapted over deep time.

End of the Road describes the human and cultural consequences of a short-sighted quest for efficiency that assigns good jobs a value of zero. Fresh and authentic, this book is a workingman’s call to save the dignity and freedom not just of truckers, but of all blue-collar workers.

Read it. Rhyme it. Remember it. The Brain-Science Method That Makes Organic Chemistry Finally Click. Organic chemistry is one of the most failed college science courses. Textbooks overload you with dense details, long mechanisms, and endless exceptions—without showing you how to make any of it stick. Rereading doesn’t build understanding. It just burns time.
