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.

Since the Industrial Revolution, our civilization has depended on fossil fuels for energy - first it was coal; then petroleum. If business as usual continues, we are looking at a world where sea levels will be high enough to submerge many coastal cities and extreme weather events like 2012’s Hurricane Sandy are the new normal. In this audiobook, The Future of Energy: Earth, Wind, and Fire, we review the energy problem and analyze the options from the mundane to the far out.

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.

The nuclear bomb ushered in a new age. The rules of warfare had to change when one act might end civilization. In this audiobook, The Changing Face of War, we examine the technologies being developed or adapted for war and defense - and what these innovations mean for the way nations (and non-state antagonists) conduct military or security operations.

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.

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.

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.

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.

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?

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.

The onset of cold weather brings out the boots, coats, gloves - and the stoplight-red “Flu Shots Available Here” signs in drugstore windows. For many scientists and public health specialists alike, flu season has become a little like Russian Roulette. The likelihood of a deadly pandemic outbreak of influenza is not far from reality considering the nature of some of the different viral strains. In this book, we delve into the science of the flu, starting with past pandemics and what we can learn from them.

An infant born in the US today will probably live more than 20 years longer than the average lifespan a century ago. While living well into the 80s and 90s is becoming more and more attainable, how many more years can humanity expect to gain? And how can we raise the quality of those later years? The two main barriers are accumulated damage to cells and organs that occurs over time and age-related illnesses like cancer and Alzheimer’s disease.

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 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.

Neuroscientists have shown that music recruits nearly every area of the brain, fostering connections across different regions. In this book, we examine the latest imaging studies and discuss the effects of music on emotion, cognition, sensation, and motor function. This includes an examination of the brain’s anatomy when listening to or creating music, of music’s relationship to learning math and language skills, and of its role in promoting social connections and treating brain disorders and injuries.

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.

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.

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.

“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.
