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.

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.

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 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.”

In the two decades since astronomers first discovered the existence of a planet outside of our solar system, “exoplanetology” has become the hottest specialty in astrophysics. Scientists young and old, inspired by the thought of finding either another habitable world or the Holy Grail of space exploration - life itself - flocked to be part of this burgeoning field. With so much brainpower on hand, it’s no wonder that investigative techniques advanced more quickly than anyone would have thought.

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.

Brain diseases such as Alzheimer’s and Parkinson’s affect an estimated one in six Americans and are increasing in incidence as the population ages. In this audiobook, we examine these and other conditions involving the damage and loss of neurons, including other forms of dementia, amyotrophic lateral sclerosis (ALS), chronic traumatic encephalopathy (CTE), and multiple sclerosis (MS).

This audiobook, Tomorrow's Medicine, looks at some of the more fascinating areas where technology that could transform health is being developed, including cybernetics, regenerative medicine, nanotechnology, and genetically tailored treatments. Although many of these advances may not be ready to treat humans for many years, some of them may someday profoundly change - and extend - our lives. As exciting as the possibilities are to extend both the length and quality of life, immortality - or at least agelessness - may be forever out of our reach.

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.

Creativity was long thought to be a gift from the muses, a special quality of a select minority of people. Fortunately, more recent studies have debunked this belief and have shown promise for techniques to help us all boost our creative potential. Nature gives some people a genetic edge, but nurture has a large role in developing creative genius. In this audiobook, we look at this difficult-to-define quality from all angles: where creativity comes from, lessons we can learn from creative geniuses, and how to cultivate creativity.

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.

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.

Genetic engineering, which refers to the direct manipulation of DNA, became a reality in the 1970s. In this audiobook, we take a look at how far the field has come, starting with a revolutionary gene-editing tool called CRISPR that’s taking the research world by storm. We then examine how CRISPR and other approaches are being investigated to treat disease, the fantastic-sounding research being done in synthetic biology, controversial efforts in modifying crops and saving species, as well as the numerous ethical issues raised in these areas.

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.

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.

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.

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 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.

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.
