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.

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.

Host Rachel Feltman, alongside leading science and tech journalists, dives into the rich world of scientific discovery in this bite-size science variety show.

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.”

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.

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books.

In the two decades since astronomers first discovered the existence of a planet outside of our solar system, “exoplanetology” has become the hottest specialty in astrophysics. Scientists young and old, inspired by the thought of finding either another habitable world or the Holy Grail of space exploration - life itself - flocked to be part of this burgeoning field. With so much brainpower on hand, it’s no wonder that investigative techniques advanced more quickly than anyone would have thought.

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.

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.

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.

Consciousness is more than mere awareness. It’s how we experience the world, how we turn input into experience. Once the province of philosophy, religion, or perhaps fantasy, neuroscientists have added a scientific voice to the discussion, using available medical technology to explore just what separates so-called “mind” from brain. In this audiobook, we look at what science has to say about one of humankind’s most fundamental, existential mysteries.

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.

Understanding why we age and how to prevent age-related physical and mental decline can help us to live in the moment and enjoy our health at any age. In this audiobook, we explore the latest thinking in why we age, strategies to help maintain good health, as well as research into the limits of human longevity.

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.

Take control and retrain your brain to achieve a happier, healthier state of mind. In this audiobook, we examine aspects of daily life that affect mood such as perception, social support, and time management and offer approaches shown to boost contentment, including reframing negative events, increasing resilience through self-compassion, and practicing mindfulness.

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.

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.

Welcome to the new old age! There has never been a better time, in all of history, to grow old. But will your brain age as well as the rest of you? In her fourth engaging book about the brain, Judith Horstman presents a realistic and encouraging overview of the well-aged brain, a sobering look at what can go wrong, and the latest in what neuroscience is finding might help you - and your brain - stay healthy longer.

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.
