The zombie has had a bit of a renaissance over the last decade. Hollywood churns out films like World War Z and TV shows like The Walking Dead, and communities throughout the country hold zombie runs and races. So what’s driving the zombie obsession? Where did the fear of this creature originate? In this audiobook, The Real Zombies of Nature, we look at the myth of the zombie versus real instances of zombification in the natural world and engage in some scientific speculation about what would happen if myth ever became reality.

Strange and probabilistic, physics at the smallest scales is driving innovation and research into the nature of reality. In this audiobook, we examine the latest mind-bending studies in quantum mechanics, including theoretical mysteries such as entanglement, real-world applications, innovations in communications and computing, and more.

Science history is chock full of world-changing innovations that initially faced skepticism and ridicule for being too unconventional: light bulbs, cars, and home computers are just a few examples. In this audiobook, we take a look at the latest out-of-the-box ideas to tackle today’s biggest challenges, including so-called sponge cities designed to combat flooding, technology that mimics photosynthesis to produce fuel, modifying bacteria’s genetic circuits to treat genetic diseases, and much more.

Until recently, one idea has dominated research in treating Alzheimer’s disease: the amyloid hypothesis. Those therapies have repeatedly fallen short, and in this audiobook we take a look at where that hypothesis stands today. We examine recent research into the spectrum of disease causes, including inflammation and immune dysfunction; cutting-edge treatments, including deep-brain stimulation and magnetic resonance - guided focused ultrasound; as well as lifestyle interventions that can help protect from disease.

The Olympics are the world’s most prestigious stage for athletic competition. Fans both casual and hardcore tune in religiously every few years to watch as men and women push themselves to the limits of human performance. But what makes a champion? Is it genetics? Hours of training? A psychological advantage? Of all the athletes who dedicate their lives - and bodies - to achieving that perfect moment of triumph, why will one person or team win out over another? Science has some compelling answers, and in this audiobook, Scientific American explores this topic from various angles.

The sense of position and movement is often called the sixth sense; the brain’s connection to the immune system might be a seventh. In this audiobook, we examine the diverse functions of the brain beyond the five senses, including the glymphatic system for maintaining brain health, the processes behind intuition, and new research raising questions about “brain death.”

From increasingly severe storms to collapsing coral reefs to the displacement of Syrian citizens, in this audiobook we examine the effects of Earth’s changing climate on weather systems, ecosystems, and human habitability and what this means for our future.

The extreme drought in the US Southwest has brought the issues of water use and management to the forefront of media attention. Historically, arguments over water rights have plagued this area since the days of John Wesley Powell, and disputes mark the relations between states, city-dwellers, farmers, and environmentalists to this day. Add to that the challenges of climate change, which is altering rainfall patterns the world over, and the imperative to rethink water-management policies becomes acute.

In science fiction, artificial intelligence takes the shape of computers that can speak like people, think for themselves, and sometimes act against us. Reality of course is vastly different, though in many ways computers surpass their fictional counterparts. This book reviews work in the field and covers topics from chess-playing to quantum computing. The writers tackle how to make computers more powerful, how we define consciousness, what the hard problems are, and even how computers might be built once the limits of silicon chips have been reached.

“Cosmos” comes from a Greek word for an orderly and systematic universe. In this book, we present the most riveting discoveries and mind-bending ideas about our cosmic home, from what we know of the origins of the universe and the cartography of space to the most bizarre phenomena and the search for life. Discussions include the possibility that the big bang was the consequence of a black hole in a fourth spatial dimension, that cosmic ripples created infinite universes, that entangled black holes could act as wormhole-like passageways through space, and much more.

Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Curiosity rover in 2012, this book traces Scientific American's coverage of the observation and exploration of Mars.

Brain diseases such as Alzheimer’s and Parkinson’s affect an estimated one in six Americans and are increasing in incidence as the population ages. In this audiobook, we examine these and other conditions involving the damage and loss of neurons, including other forms of dementia, amyotrophic lateral sclerosis (ALS), chronic traumatic encephalopathy (CTE), and multiple sclerosis (MS).

Did NASA really spend millions creating a pen that would write in space? Is chocolate poisonous to dogs? Does stress cause gray hair? These questions are a sample of the urban lore investigated in this audiobook, Fact or Fiction: Science Tackles 58 Popular Myths. Drawing from Scientific American’s “Fact or Fiction” and “Strange But True” columns, we’ve selected 58 of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

This audiobook contains a collection of columns written by Claudia Wallis, an award-winning science journalist whose work has appeared in The New York Times, Time, Fortune, and the New Republic. Claudia was the science editor at Time and the former managing editor of Scientific American Mind. Together, these stories will demystify recent medical research and developments and expand your understanding of how these developments impact the mind and body.

Why can you vividly recall the day your father took you to your first baseball game many years ago, but you can’t remember where you just put the car keys? The process of how - and what - we remember is a fascinating window into who we are and what makes us tick. In this audiobook, we explore what science can and can’t tell us about memory.

Once dismissed as a mathematical curiosity, black holes are so strange they almost defy belief. Since their existence was confirmed, research into the nature of black holes has opened up new vistas in physics. In this audiobook, we examine some of the most fascinating discoveries about black hole formation and behavior, the new and evolving research in gravitational wave astronomy, theoretical possibilities such as wormholes, and much more.

Chronic stress makes people sick. The fight-or-flight response activates our bodies to face immediate threats, but that stress system must turn off to allow organs to recover. Constant anxiety keeps the system active, and in this audiobook we examine the effects of ongoing stress and trauma on both body and mind as well as ways to arm ourselves against adversity by managing stress and building resilience.

In the digital age, information, both true and false, spreads faster than ever. The same technology that provides access to data across the globe can abet the warping of truth and normalization of lies. In this audiobook, we examine the intersection of truth, untruth, and technology, including how social media manipulates behavior, technologies such as deepfakes that spread misinformation, the bias inherent in algorithms, and more.

Sally Ride, the first American woman to go to space, once said that she didn’t set out to be a role model, but after her first flight, she realized that she was one. Like her, the 12 women scientists in this collection became unintentional heroes through perseverance and hard work, making great discoveries in all areas of science. From Vera Rubin’s examination of the internal dynamics of galaxies to Nobel Prize winner May-Britt Moser’s study of the brain’s GPS-like navigation system, Trailblazers highlights the achievements of women who became role models for us all.

Burning. Shooting. Stabbing. Sometimes the cause is unknown. Sometimes it begins as the result of an injury. Whatever form it takes, chronic pain often resists treatment. In this audiobook, we examine the latest advances in understanding the pathology of chronic pain and the efforts to find better, non-opioid treatment options, including electrical stimulation of nerves, venom from spiders and other creatures, and psychological interventions including virtual-reality therapy and acupuncture.
