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.

This fascinating and highly accessible book presents fantastic but totally feasible projections of what your brain may be capable of in the near future. It shows how scientific breakthroughs and amazing research are turning science fiction into science fact. In this brave new book, you'll explore.

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.

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.

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.

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.

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.

People say that they trust scientists, yet evidence often takes a back seat to emotions. In fact, for issues that cause the loudest public furor - like vaccine safety - there is almost no debate in the scientific community. This audiobook examines the science behind today’s most contentious debates - including gun control, GMOs, and evolution, as well as strategies for understanding and coping with denialism.

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.

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?

People behave in strange ways. We sometimes giggle when someone falls down, swear we've been to places we haven't, or continue believing in something despite scientific evidence to the contrary. For more than a decade, Scientific American MIND's long-running feature "Ask the Brains" has addressed questions from their readers on the quirks and quandaries of human behavior, psychology, and neurology. Here, in Ask the Brains, Part 1, they’ve compiled some of the best and most interesting inquiries about the human brain.

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.

Creationists, or those who hold the belief that the universe and all life was made by divine creator, have tried to use a myriad of tactics either to ban the teaching of evolution entirely or to have creationism and intelligent design taught alongside one another in public schools. In Evolution vs. Creationism, we take a close look at the rise of Darwinism, the arguments and opposition by the creationist movement, whether faith and science can coexist, and what could happen if the US continues on an anti-science trajectory.

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 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.

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 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.

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.

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.
