“Cosmos” comes from a Greek word for an orderly and systematic universe. In this book, we present the most riveting discoveries and mind-bending ideas about our cosmic home, from what we know of the origins of the universe and the cartography of space to the most bizarre phenomena and the search for life. Discussions include the possibility that the big bang was the consequence of a black hole in a fourth spatial dimension, that cosmic ripples created infinite universes, that entangled black holes could act as wormhole-like passageways through space, and much more.

We harbor roughly the same number of microbes as we have cells. This complex ecosystem is crucial to our health, affecting many processes including immunity, child development, and bone density regulation. Research in this area has exploded, and in this audiobook, we highlight some of the most exciting work on how the microbiome develops, its influence on brain and behavior, and implications in both contributing to and treating various disorders.

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.

After smartphones, smart TVs, smart windows, and other smart products on the horizon, smart cities were the next logical step in trying to create a better, brighter, more sustainable, and economically sound future. A relatively new term, smart cities conjures images of a cooperative, wired, prosperous utopia where citizens of all classes achieve a high quality of life. In this audiobook, we look at the qualities needed for future cities to survive and thrive.

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.

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.

Addiction is costly on many levels to the individuals affected, their families, and society as a whole, but science may soon be able to offer treatment options to make the road to recovery a little smoother. First, we investigate why and how people succumb to a veritable prison of the mind as sections one and two delve respectively into the psychology and the neurochemistry behind addiction. Subsequent sections break out addictive substances individually: recreational drugs, prescription drugs, alcohol, and nicotine. Finally, section seven examines new avenues for overcoming addiction.

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.

Anxiety and depression are two of the most common conditions affecting mental health and overall quality of life, but there are tools for managing them. In this audiobook, we’ll explore how depression shows up in the brain, different manifestations of depression and anxiety, various talk therapies, technological innovations, lifestyle interventions, and 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.

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.

Autism is one of three diagnoses that the DSM-5 includes in autism spectrum disorder (ASD). While our understanding of this condition has grown exponentially, research has been fraught with controversy. Autism appears to be on the rise, depending on how you define it, and its causes more complex than imagined.

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.

One of the biggest discoveries in physics, the quest for the Higgs boson demonstrates the value of a good theory. In July 2012, a Higgs-like particle was found near the energies scientists predicted. Now, armed with better evidence and better questions, the scientific process continues. In this audiobook, we’ve gathered our best reporting to explain that process - the theories, the search, the discovery, and the ongoing questions.

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.

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.

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.

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.

Boy or girl? Even before a person is born, that’s the first thing everyone wants to know - underscoring just how much value human societies of all types place on gender. In His Brain, Her Brain, we take a closer look at the anatomical, chemical, and functional differences in the brains of men and women - as well as some surprising similarities. For instance, studies of infants find few differences in cognitive skills between boys and girls; but there is no denying that boys love trucks, whereas girls prefer dolls.

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.
