Why does it feel like something to be alive? For one of the boldest thinkers in neuroscience, solving this puzzle has been a lifetime's quest. Now at last, Mark Solms, who discovered the brain mechanism for dreaming, has arrived at his answer. More than just a philosophical argument, the Free Energy theory will profoundly change how you understand your own existence.

On his popular science blog, Pharyngula, PZ Myers has entertained millions of fans with his infectious love of evolutionary science and his equally infectious disdain for creationism, biblical literalism, intelligent design theory, and other products of godly illogic. This funny and fearless book collects and expands on some of his most popular writings, giving the religious fanaticism of our times the gleeful disrespect it deserves by skewering the apocalyptic fantasies, magical thinking, hypocrisies, and pseudoscientific theories advanced by religious fundamentalists of all stripes.

A young man is murdered for his prized pet fish. An Asian tycoon buys a single specimen for $150,000. Meanwhile, a pet detective chases smugglers through the streets of New York. Delving into an outlandish realm of obsession, paranoia, and criminality, The Dragon Behind the Glass tells the story of a fish like none other: a powerful predator dating to the age of the dinosaurs.

We are living through the most prosperous age in all of human history, yet we are listless, divided, and miserable. Wealth and comfort are unparalleled, but our political landscape is unmoored, and rates of suicide, lone­liness, and chronic illness continue to skyrocket. How do we explain the gap between these truths? And how should we respond? For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our troubles is clear: The accelerat­ing rate of change in the modern world has outstripped the capacity of our brains and bodies to adapt.

According to R. Douglas Fields, PhD, we all have a rage circuit we can't fully control once it is engaged. The daily headlines are filled with examples of otherwise rational people with no history of violence or mental illness suddenly snapping in a domestic dispute, barroom brawl, or road rage attack. We all wish to believe that we are in control of our actions, but the fact is, in certain circumstances we are not. Something in our environment can unexpectedly unleash an automatic and complex rage response.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Oxford Case Histories in Infection and Microbiology contains over 45 well structured cases, providing comprehensive coverage of the diagnostic and management dilemmas in clinical microbiology and infectious diseases. Each case comprises of a brief patient history with relevant clinical examination findings, thus insuring the listener is aware of how to confirm a diagnosis rapidly, with reference throughout to laboratory techniques, advice on therapy, epidemiological features, and areas which can be controversial.

For the first time in history, the secrets of the living brain are being revealed by a battery of high-tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist.

The “winner effect” is a term used in biology to describe how an animal that has won a few fights against weak opponents is much more likely to win later bouts against stronger contenders. As Ian Robertson reveals, it applies to humans, too. Success changes the chemistry of the brain, making you more focused, smarter, more confident, and more aggressive. The effect is as strong as any drug. And the more you win, the more you will go on to win. But the downside is that winning can become physically addictive.

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

Human bone is versatile and entirely unique: It repairs itself without scarring, it's lightweight but responds to stresses, and it's durable enough to survive for millennia. In Bones, orthopedic surgeon Roy A. Meals explores and extols this amazing material that both supports and records vertebrate life.

In Cow Hug Therapy, Ellie Laks recounts the extraordinary journey that started with her first teacher, Buddha—not the religious figure, but a rescued miniature Hereford cow. One evening Buddha wrapped her neck around an exhausted and upset Ellie and transferred a singular form of healing and comfort with an incredible impact. Understanding that this was something to be shared with others, Ellie developed Cow Hug Therapy, a groundbreaking approach to emotional healing that has proved effective for trauma, illness, disabilities, addiction, grief, and stress.

We have a lifetime's association with our bodies, but for many of us they remain uncharted territory. In Adventures in Human Being, Gavin Francis leads the listener on a journey through health and illness, offering insights on everything from the ribbed surface of the brain to the secret workings of the heart and the womb; from the pulse of life at the wrist to the unique engineering of the foot.

Religious fundamentalists and biblical literalists present any number of arguments that attempt to disprove evolution. Those with a sympathetic ear often fail to critically examine these creationist claims, leading to an ill-informed public and, perhaps more troubling, ill-advised public policy. As Aron Ra makes clear, however, every single argument deployed by creationists in their attacks on evolution is founded on fundamental scientific, religious, and historical falsehoods - all of them.

Fungi can appear anywhere, from desert dunes to frozen tundra. They can invade our bodies and live between our toes or our floorboards. They are unwelcome intruders or vastly expensive treats, and symbols of both death and eternal life. But despite their familiar presence, there’s still much to learn about the eruption, growth, and decay of their secret interconnected world. From fields, feasts, and fairy rings to death caps, puffballs, and ambrosia beetles, this is an intoxicating journey into the life of an extraordinary organism, one that we have barely begun to understand.

What does it mean to “be you” - that is, to have a specific, conscious experience of the world around you and yourself within it? There may be no more elusive or fascinating question. Historically, humanity has considered the nature of consciousness to be a primarily spiritual or philosophical inquiry, but scientific research is now mapping out compelling biological theories and explanations for consciousness and selfhood.

This is a story about you. It is the history of who you are and how you came to be. It is unique to you, as it is for every one of the 100 billion modern humans who has ever drawn breath. But it is also our collective story, because in each of our genomes we carry the history of the whole of our species.

There is a scientific revolution stirring in the field of human perception. Research has shown that the extraordinary sensory powers of our animal friends can help us better understand the same powers that lie dormant within us....

This dynamic chronicle of the race to find the "missing links" between humans and apes transports readers into the highly competitive world of fossil hunting and into the lives of the ambitious scientists intent on pinpointing the dawn of humankind. The quest to find where and when the earliest human ancestors first appeared is one of the most exciting and challenging of all scientific pursuits.
