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.

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.

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.

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.

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.

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.

Why do facts fail to change people’s minds? In this audiobook, we examine how we form our beliefs and maintain them with a host of cognitive biases, the difference between intelligence and thinking rationally, and some solutions for how to overcome these obstacles both in reasoning with others and in dealing with our own prejudices.

From irrational phobias to a midlife crisis, we’ve all experienced moments of utter confusion about the nature of our own behavior, emotions, or perception of reality. In this audiobook, neurologists and other scientists share what they know about how the mind works, including some of these baffling psychological experiences.

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.

Love - in both the abstract and the up-close-and-personal - has always provided limitless inspiration for artists, writers, and musicians, but scientists are just as fascinated by these affairs of the heart, though they seldom sing about it. In Love, Sex, and Science, our editors take a step back, analyzing romance using tools like fMRI studies instead of a paint brush or guitar. The writers examine a variety of topics, starting with the perceived sex differences between men and women discussed in Section 1 - are we really as different as Mars and Venus?

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.

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.

For more than a century, scientists across disciplines have investigated the workings of nature’s most complex organ. Findings from cutting-edge neuroscience are moving us closer to understanding processes like how we make decisions or navigate our environment. In this audiobook, we examine the latest research on cognition, how the brain gives rise to consciousness, and how we can improve mental health.

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.

From increasingly severe storms to collapsing coral reefs to the displacement of Syrian citizens, in this audiobook we examine the effects of Earth’s changing climate on weather systems, ecosystems, and human habitability and what this means for our future.

In Cyber Hacking: Wars in Virtual Space, we peer behind the cyber curtain. First, we look at the hackers - who they are, how they work, their motivations, and methods. The opening article examines hardware - specifically microprocessors and why they are vulnerable to tampering. Then we turn to the internal attacks, the worms and viruses whose resulting damage ranges from merely inconvenient and attention-getting to expensive and dangerous. Next, we take a broad look at issues of privacy and the technology used to gather and track personal information.

With global population numbers projected to increase by two billion by 2050, a veritable food crisis is on the horizon. In this audiobook we examine some of the complex factors involved in the coming “food crisis” and the innovative ideas and technologies designed to increase food production sustainably. We also examine current industry methods to increase production and the controversies surrounding them, including not only hot-button issues like genetically modified (or GM) and processed foods but also food safety and the physical effects of the modern diet.

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.

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.

Making ethical decisions involves more than listening to an inner moral compass, a feeling in the gut of what’s right and wrong. Questions of ethics in science are becoming increasingly complex, especially as technology encroaches upon even our most private cellular spaces. In Doing the Right Thing: Ethics in Science, we cover a wide range of areas in science and medicine where complicated ethical questions come to bear, including genomics and research where informed - and ethically sound - choices are the basis of many scientific studies.
