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.

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.

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.

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.

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.

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.

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"?

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.

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.

Once dismissed as a mathematical curiosity, black holes are so strange they almost defy belief. Since their existence was confirmed, research into the nature of black holes has opened up new vistas in physics. In this audiobook, we examine some of the most fascinating discoveries about black hole formation and behavior, the new and evolving research in gravitational wave astronomy, theoretical possibilities such as wormholes, and much more.

In the digital age, information, both true and false, spreads faster than ever. The same technology that provides access to data across the globe can abet the warping of truth and normalization of lies. In this audiobook, we examine the intersection of truth, untruth, and technology, including how social media manipulates behavior, technologies such as deepfakes that spread misinformation, the bias inherent in algorithms, and more.

The sense of position and movement is often called the sixth sense; the brain’s connection to the immune system might be a seventh. In this audiobook, we examine the diverse functions of the brain beyond the five senses, including the glymphatic system for maintaining brain health, the processes behind intuition, and new research raising questions about “brain death.”

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.

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.

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.

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?

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?

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.

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.

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.
