Many scientists and doctors believe that there is no such thing as the soul. That there is no part of us that persists beyond death. We are not spiritual in any respect. We are made up of cells and tissue, and completely controlled by a material organ in our heads: the brain. In this groundbreaking book, Dr. Michael Egnor makes the case—based on 40 years of practice and over 7,000 brain surgeries—that science has gotten it all wrong.

This book investigates the interesting question about the size of the Universe.

Hearing is the first sense we develop—a primary warning instinct hardwired into our brains. And yet, in an increasingly noisy and distracted world, most people pay very little attention to sound. In school, we teach reading and writing, but not listening. Conscious listening is rare, and, with over half the world's population now living in cities, billions of people never experience the rich and health‑enhancing sounds of the natural world. Every day, the sounds around us affect our experience and fundamentally alter our quality of life, for better or worse.

Chaos magic emerged only a few decades back, but it has already grown into a magical tradition embraced by many. Chaos magic started under the influence of renowned artist and occultist Austin Osman Spare; it was then codified by Peter J. Carroll and a few others. This Is Chaos delves into the history the magical system has come from, but more importantly looks at its use and what the future holds. Chaos magic has always been about pushing boundaries with a focus on belief utilizing aspects of magic.

Submersed begins with an investigation into the beguiling subculture of DIY submersible obsessives: men and women—but mostly men—who are so compelled to sink into the deep sea that they become amateur backyard submarine-builders. Matthew Gavin Frank explores the origins of the human compulsion to sink to depth, from the diving bells of Aristotle and Alexander the Great to the Confederate H. L. Hunley, which became the first submersible to sink an enemy warship before itself being sunk during the Civil War.

The science is in: being good is actually good for you. In The Biology of Kindness—the first in a trilogy on the topic of daily wellness—the science of mindfulness and the findings of biology come together to show how kindness and optimism improve overall well-being in profound, organic, and demonstrable ways. Daniel Lumera, an expert in meditation and mindfulness, and Immaculata De Vivo, a preeminent researcher in molecular epidemiology, outline a revolutionary approach to health, longevity, and quality of life—and explain the scientific evidence that supports their work.

Shifting Sands is about that other Sahara, not the empty wasteland of the romantic imagination but the vast and highly differentiated space in which Saharan peoples and, increasingly, new arrivals from other parts of Africa live, work, and move. It takes us from the ancient Roman Empire through the bloody colonial era to the geopolitics of the present, questioning easy clichés and exposing fascinating truths along the way.

In 2011, a lone wolf named Slavc set out from his home territory of Slovenia on an epic journey across the Alps. Tracked by a GPS collar, he walked over a thousand miles. In Italy he bumped into a female wolf on a walkabout of her own—the only two wolves for hundreds of square miles—and when they mated, they formed the first pack to call these mountains home in over a century. Today there are more than a hundred wolves in the area, the result of their remarkable meeting.

Employing in-depth reporting on cutting edge science and technology, veteran journalist Thomas E. Weber takes us on a tour of how meteorologists, scientists, and officials track and prepare for major weather events.

We’ve all heard the story about waking up as a cockroach—but what if a crisis turned you into a clam? After the dissolution of her marriage, a writer is transformed into a “clam” via typo after her mother keeps texting her to “clam down.” The funny if unhelpful command forces her to ask what it means to “clam down”—to retreat, hide, close up, and stay silent. Idiomatically, we are said to “clam up” when we can’t speak, and to “come out of our shell” when we reemerge, transformed.
