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.

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.

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.

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.

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.

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.

During allergy season, sufferers know the drill: runny nose, watery eyes, sneezing up a storm. For the unlucky with asthma, symptoms might also include coughing and wheezing. However, asthma is not always caused by allergens like pollen and dust - nonallergenic asthma is brought on by a number of possible environmental or genetic triggers. Then there’s the common cold, which also presents with similar symptoms. So what’s causing your runny nose?

Self-improvement is a lifelong quest. We all have things we’d like to change about ourselves, which is why many people make New Year’s resolutions. Yet, research shows that only about 8 percent of resolution makers achieve their goals. Changing personal habits is both hugely difficult and hugely rewarding. Here, Scientific American offers this guide on breaking bad habits and the ultimate satisfaction of making difficult life changes.

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.

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.

Everything from neurons to consciousness in the blink of an eye (which takes 300 milliseconds). Take a "fantastic voyage" through the whorls and curves of the human brain, no miniaturization required. Learn everything from how quickly you can possibly think (and that left-handed people think...
