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.

In The Science of Cancer, we examine what we know and what we’re finding out about this scourge of humankind. We delve into the molecular basis and complex causes of cancer, the arguments for and against screenings, minimizing risk, and several new and targeted therapies, including homing in on stem cells, making use of viruses, and making use of vaccines to jump-start the immune system.

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.

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.

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.

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.

The science of education is elusive. Educators, academics, and scientists have struggled with issues like how to make learning approachable yet challenging, what to include in the curriculum and when, what the optimal class size is, and so on. In this collection, we explore the many ways that learning is also a scientific process and offer the latest theories of teaching and learning.

Creativity was long thought to be a gift from the muses, a special quality of a select minority of people. Fortunately, more recent studies have debunked this belief and have shown promise for techniques to help us all boost our creative potential. Nature gives some people a genetic edge, but nurture has a large role in developing creative genius. In this audiobook, we look at this difficult-to-define quality from all angles: where creativity comes from, lessons we can learn from creative geniuses, and how to cultivate creativity.

How do we define genius? Standardized testing to measure intelligence began in the first half of the 20th century, but a high IQ score is only one way to quantify genius. In this audiobook, Eureka! The Science of Genius, we review the latest research on the nature of intellectual and creative achievement, including traits that geniuses tend to share, how much of their ability is nature versus nurture, the cognitive processes involved during the stages of discovery and creativity, and, most importantly, what we can do to enhance intelligence.

If climate catastrophes like Hurricane Sandy seem to be on the rise, it’s for a reason. The likelihood of these extreme weather events are increasingly being tied to man-made global warming, mostly through overproduction of carbon dioxide. It’s no longer an abstract idea; it’s being felt locally, on every level. Climate Change and Extreme Weather gives you the tools to better understand what’s behind climate change, what might be in store during the coming decades, and how we can begin to reverse the detrimental effects mankind has had on the atmosphere.

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.

The Book of Revelation, the Maya, Nostradamus - humans have speculated about the end since, well, the beginning. In this book, we look at several “end of the world” scenarios - or at least, things that could make human life really difficult.

Science fiction has imagined some pretty wild ideas about how the universe could work - from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared to the mind-bending science now coming out of physics and astronomy, and in this audiobook, we look at the strange and fascinating discoveries shaping (and reshaping) the field today.

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.

While many of us strive to live healthy lives, the task can be daunting and the information overwhelming. Should we be more concerned with our diet or with keeping our weight down? How important is exercise? What kinds of diseases should we really be worried about getting - or preventing? In Eat, Move, Think: Living Healthy, we’ve assembled a number of stories on what we think sums up a healthy lifestyle, as well as some of the common obstacles faced in trying to achieve it.

The fourth book in our Ask the Experts series, The Environment tackles questions about the world around us. In this book, our experts field queries on the weather, natural disasters, natural resources, climate change, and unusual phenomena.

The reason we need sleep has long mystified scientists, but it’s crystal clear that we do need it. In fact, the more we learn about what happens while we snooze, the more we discover new benefits for multiple processes including hormone balance, immune function, emotional health, learning, and memory. Studies show that even one night of disturbed rest leads to measurable impairments, and for this mini-collection, we’ve gathered the most recent research on the mechanisms of sleep.

The Science of Diet & Exercise examines traditional weight loss advice and finds it wanting. Data shows that the kinds of foods you eat are as important as how much you eat, and studies of physically active hunter-gatherers illustrate that energy expenditure (caloric burn) stays virtually constant, regardless of activity. The nine articles in this collection present the most recent research examining the details of the metabolic process and testing new approaches, some of which can be applied to how we think about diet and exercise today.

How did life begin on Earth? Does it exist elsewhere? What would those life forms be like? These fundamental questions about the nature of life and our own cosmic significance are endlessly fascinating. In this book, we present several theories on the origin of life, some of its extreme and surprising forms, and the ongoing search for signs - or sentience - on distant worlds.

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.
