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.

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.

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"?

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.

Host Rachel Feltman, alongside leading science and tech journalists, dives into the rich world of scientific discovery in this bite-size science variety show.

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.

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.

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.

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.

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?

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).

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.

On June 5, 1981, the scientific community received a wake-up call from the CDC in the form of a terrible new illness that the world would soon know as AIDS. Three decades later, remarkable progress has been made, but much more remains to be understood and to be done. In this audiobook, we explore where the disease came from, how it works, how it spreads, the search for a vaccine, and cultural and sociological factors.

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books.

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.

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.

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 fundamental outlines of the physical world, from its tiniest particles to massive galaxy clusters, have been apparent for decades. Does this mean physicists are about to tie it all up into a neat package? Not at all. Just when you think you’re figuring it out, the universe begins to look its strangest, and this book illustrates how answers often lead to more questions and open up new paths to insight.

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.”

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.
