How exactly do children become the adults they were meant to be? In this audiobook, Understanding Child Development, we investigate this profoundly complicated process from infancy through early childhood (the teenage years will be covered in a separate audiobook). Included in this collection are several seminal studies on infant cognition where researchers found evidence that many of our abilities are “pre-programmed.”

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.

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 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.

Vital research is starting to challenge long-standing assumptions about gender identity and biological sex, such as work that indicates the brain is a “mosaic” of traits rather than a “male” and “female” brain. Growing knowledge of the genetic complexities of sexual determination is changing the way the medical community treats intersex individuals, and in this audiobook, The New Science of Sex and Gender, we not only examine the latest studies in biology, medicine, and psychology but also, more importantly, their bearing on healthcare, identity, and access.

In this installment of the Ask the Experts series, Chemistry, our professors, scientists, and researchers tackle reader questions about the substances that compose all matter, their properties, and how they interact and change. Queries range from elementary questions, such as why some elements change color over a flame, to how chemistry works in everyday life, to how certain substances affect the body and more.

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.

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.

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.

This fascinating and highly accessible book presents fantastic but totally feasible projections of what your brain may be capable of in the near future. It shows how scientific breakthroughs and amazing research are turning science fiction into science fact. In this brave new book, you'll explore.

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.

Politics makes strange bedfellows, and that becomes even more apparent when trying to analyze the science of politics. Pulling from an array of disciplines including social science, behavioral science, and mathematics, this audiobook analyzes key factors in the process of electing a leader: from dissecting those qualities considered to be ideal, to how potential leaders are portrayed, to voter behavior, to the voting process - casting, collecting, and counting the votes.

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.

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.
