The editors of Scientific American’s best-selling Fact or Fiction: Science Tackles 58 Popular Myths return with Fact or Fiction 2: 50 (More) Popular Myths Explained. We cast an analytical eye on another collection of urban lore and cultural myths that persist so long in our collective consciousness they acquire a ring of truth. Who hasn’t heard the “five-second rule”, which insists that food dropped on the floor is safe to eat if it’s picked up within five seconds? How many of us have been told to “feed a cold, starve a fever"?

For more than a century, scientists across disciplines have investigated the workings of nature’s most complex organ. Findings from cutting-edge neuroscience are moving us closer to understanding processes like how we make decisions or navigate our environment. In this audiobook, we examine the latest research on cognition, how the brain gives rise to consciousness, and how we can improve mental health.

People behave in strange ways. We sometimes giggle when someone falls down, swear we've been to places we haven't, or continue believing in something despite scientific evidence to the contrary. For more than a decade, Scientific American MIND's long-running feature "Ask the Brains" has addressed questions from their readers on the quirks and quandaries of human behavior, psychology, and neurology. Here, in Ask the Brains, Part 1, they’ve compiled some of the best and most interesting inquiries about the human brain.

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.

Instead of “what if the South won the Civil War?” cosmologists ask, “what if the constants that make up the fundamental building blocks of physics were different?” Physicists argue that any slight change to the laws of physics would mean a disruption in the evolution of the universe - and our existence. With the many factors that had to align for us to exist, it can seem like the laws of physics might seem finely tuned to make our existence possible. Instead of a supernatural or divine explanation, this book explores the possibility is that our universe isn’t the only one.

We humans are a strange bunch. We have self-awareness and yet often act on impulses that remain hidden. How did we get here? What is to become of us? To these age-old questions, science has in recent years brought powerful tools and reams of data, and in this audiobook, Becoming Human, we look at what this data has to tell us about who we are.

This audiobook, Tomorrow's Medicine, looks at some of the more fascinating areas where technology that could transform health is being developed, including cybernetics, regenerative medicine, nanotechnology, and genetically tailored treatments. Although many of these advances may not be ready to treat humans for many years, some of them may someday profoundly change - and extend - our lives. As exciting as the possibilities are to extend both the length and quality of life, immortality - or at least agelessness - may be forever out of our reach.

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.

The second title in our series - Astronomy - looks skyward and explains a variety of universal phenomena and theories. Are you curious about how planets acquire rings or what creates those gorgeous spiral arms around galaxies? Or maybe you want to know why the Big Bang didn’t collapse into a black hole. Astrophysicists, professors, and scientists tackle questions about stars, planets, asteroids, galaxies, and nebulae, the expanding universe as well as the oddities - black holes, wormholes, and dark matter.

“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.

We humans tend to think that we are unique in our intelligence, social skill, and depth of emotion, but we think too much of ourselves. The animal kingdom teems with hidden stories of the weird and fascinating, and in Amazing Animals, we gather recent research on animal behavior, including surprising discoveries of how animals think and feel, from man’s best friend to some of the earth’s oddest creatures.

Boy or girl? Even before a person is born, that’s the first thing everyone wants to know - underscoring just how much value human societies of all types place on gender. In His Brain, Her Brain, we take a closer look at the anatomical, chemical, and functional differences in the brains of men and women - as well as some surprising similarities. For instance, studies of infants find few differences in cognitive skills between boys and girls; but there is no denying that boys love trucks, whereas girls prefer dolls.

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.

An infant born in the US today will probably live more than 20 years longer than the average lifespan a century ago. While living well into the 80s and 90s is becoming more and more attainable, how many more years can humanity expect to gain? And how can we raise the quality of those later years? The two main barriers are accumulated damage to cells and organs that occurs over time and age-related illnesses like cancer and Alzheimer’s disease.

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.

The nuclear bomb ushered in a new age. The rules of warfare had to change when one act might end civilization. In this audiobook, The Changing Face of War, we examine the technologies being developed or adapted for war and defense - and what these innovations mean for the way nations (and non-state antagonists) conduct military or security operations.

Many factors - personal, professional, and psychological - combine to affect how we think, feel, and act while on the job, which ultimately affects our productivity and success. In 9 to 5: Your Mind at Work, we look at some of these factors, including the physical office space, how to foster creativity and communication, the psychology of effective leadership, the benefits and importance of diversity, and achieving work-life balance.

Have you ever wondered why humans lost their body hair? Curious about what causes a hangover? Or what makes that popping sound when we crack our knuckles? What about the oft-cited maxim that we only use 10 percent of our brains? Professors, scientists, and biologists provide answers that are at once accurate, understandable, and sometimes just plain funny.

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.

Take control and retrain your brain to achieve a happier, healthier state of mind.
