How does a neural network become a brain? While neurobiologists investigate how nature accomplishes this feat, computer scientists interested in AI strive to achieve this through technology. The Self-Assembling Brain tells the stories of both fields, exploring the historical and modern approaches taken by the scientists pursuing answers to the quandary: What information is necessary to make an intelligent neural network? As Peter Robin Hiesinger argues, "the information problem" underlies both fields.

"Jeg blødte over det hele, havde brækket anklen og fået et slag på rygsøjlen. Lægerne sagde, at næsen bliver ved med at løbe resten af mit liv. Er det det værd? Gu' fanden er det fucking det værd ..." Tag med på en rejse ind i et lukket univers, hvor fodbold er mere end en hobby, og ære betyder alt. For første gang fortæller topfolk fra Danmarks tre største hooliganfraktioner om livet i fodboldens underverden.

An esteemed professor of biology at Wheaton College, John Kricher leads a fascinating discussion of the approximately 10,000 species of birds that share our world. In these engaging lectures, Kricher expands on such topics as bird anatomy, the mechanics of flight, migration, reproduction, and song. The professor's lively presentation demonstrates how understanding the traits, life cycle, and evolution of birds is critical for an understanding of the origins and evolution of life on earth - and why conservation plays a vital role in the environment's delicate balance.

Listen in as Seeker answers some unbe-leaf-able questions like how plants can grow without water, how plants defend themselves, and how they eat animals. You’ll also learn about the future of plants - from growing them in space and how artificial leaf technology will change the world - all in this best-of collection available for the first time in audio.

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.

From Parkinson’s disease to Tourette’s syndrome and depression to psychopathy, Broken Brains reveals the mysteries of brain function - and dysfunction. In this no-nonsense introduction, Ian Mitchell takes you on a tour through the sometimes devastating and sometimes bizarre effects of what happens when brains break down.

The Memory Thief is the remarkable true story of a team of doctors who - through years of scientific sleuthing and observant care - discover a surprising connection between opioids and memory, one that holds promise and peril for any one of us.

An invisible world of astonishing complexity is all around you. A world so small you can’t see it with the naked eye. A world so crowded that its population staggers the mind. A world in which you participate every day - often without even knowing it. The inhabitants of this world are trillions of bacteria, viruses, fungi, and other organisms, collectively known as microbes. Hundreds of thousands could fit on the period at the end of this sentence. And many play a powerful role in your life.

Chemistry and Our Universe: How It All Works is your in-depth introduction to this vital field, taught through 60 engaging half-hour lectures that are suitable for any background or none at all. Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

A true scientific pause-resister that traces a remarkable scientific breakthrough (the isolation of endorphins in the brain) as dedicated scientists race - not only with their fellow scientists - but against time and the profit hungry giant pharmaceutical companies. This audiobook chronicles the fascinating discovery of endorphins, the body's natural painkiller.

Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end.

Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how.

When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don't see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones and Bird Songs guides the listener through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter.

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).

Many are familiar with the commonly known senses - sight, hearing, taste, smell, and touch. But most do know realize that humans have other senses beyond these. This is not, however, a spooky "sixth sense" of extrasensory perception. But humans do have a different kind of sixth sense. We also have a seventh sense, and it can be debated that we have even more. These additional senses are in fact specialized systems to detect other aspects of the world that we rarely consider, though they are an important part of our everyday life.

James T. Costa takes listeners on a journey from Darwin's youth and travels on the HMS Beagle to Down House, his bustling home of 40 years. We accompany Darwin in his myriad pursuits against the backdrop of his enduring marriage, chronic illness, grief at the loss of three children, and joy in scientific revelation. At each chapter's end, Costa shows how we, too, can investigate the wonders of nature at work, with directions on how to re-create Darwin's experiments.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

Presenting scientific evidence from diverse fields, including anthropology, biology, and psychology, Fuentes devises a myth-busting toolkit to dismantle persistent fallacies about the validity of biological races, the innateness of aggression and violence, and the nature of monogamy, sex, and gender. This revised and expanded edition provides up-to-date references, data, and analyses, and addresses new topics, including the popularity of home DNA testing kits and the lies behind ‘"incel" culture.

Written by experts and authorities in the field and professionally narrated for easy listening, this crash course is a valuable tool both during school and when preparing for the USMLE, or if you're simply interested in the subject. The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical medical school Human Anatomy course. Included are both capsule and detailed explanations of critical issues and topics you must know to master the course.
