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.

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.

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?

Is time an illusion? Is time travel possible? Could time end? In this audiobook, A Question of Time, we take an interdisciplinary look at the fourth dimension, exploring the latest thinking on the nature of time and the ways it dominates our physical and mental worlds.

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.

How many people achieve a cult following because of their writing in mathematics? Only a handful, and Martin Gardner is among the most well-known and well-loved. Not only did he present a notoriously difficult subject in an engaging and accessible way, but in doing so, he attracted an incredibly broad readership. His “Mathematical Games” column in Scientific American ran nearly every month for 26 years and was one of the most popular in the magazine’s history.

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.

Terrible lizards. That’s what the word dinosaurs means. Yet dinosaurs are not true lizards, and they are not necessarily terrible, either. Paleontologists have overturned many misconceptions, and in Dinosaurs!, we look at what the latest research tells us and what we still have to learn about these endlessly fascinating creatures.

In this audiobook, The Human Odyssey, we explore the evolution of those characteristics that make us human. The first section looks at our family tree and why some branches survived and not others. Swings in climate are emerging as a factor in what traits succeeded and failed; meanwhile, DNA analyses show that Homo sapiens interbred with other human species, which played a key role in our survival.

On June 5, 1981, the scientific community received a wake-up call from the CDC in the form of a terrible new illness that the world would soon know as AIDS. Three decades later, remarkable progress has been made, but much more remains to be understood and to be done. In this audiobook, we explore where the disease came from, how it works, how it spreads, the search for a vaccine, and cultural and sociological factors.

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"?

The zombie has had a bit of a renaissance over the last decade. Hollywood churns out films like World War Z and TV shows like The Walking Dead, and communities throughout the country hold zombie runs and races. So what’s driving the zombie obsession? Where did the fear of this creature originate? In this audiobook, The Real Zombies of Nature, we look at the myth of the zombie versus real instances of zombification in the natural world and engage in some scientific speculation about what would happen if myth ever became reality.

The Olympics are the world’s most prestigious stage for athletic competition. Fans both casual and hardcore tune in religiously every few years to watch as men and women push themselves to the limits of human performance. But what makes a champion? Is it genetics? Hours of training? A psychological advantage? Of all the athletes who dedicate their lives - and bodies - to achieving that perfect moment of triumph, why will one person or team win out over another? Science has some compelling answers, and in this audiobook, Scientific American explores this topic from various angles.

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.

In the US, more than half of households have a pet - usually more than one. They’re usually considered members of the family, and some of us even call them our “furry children”. The strength of the human-pet bond tells us as much or more about ourselves as it does about our pets, and in this audiobook, we look at why dogs and cats behave the way they do and what makes our bond with them so strong.

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.

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.

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...

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.
