When we think of the forces driving cancer, we don’t necessarily think of evolution. But evolution and cancer are closely linked, for the historical processes that created life also created cancer. The Cheating Cell delves into this extraordinary relationship, and shows that by understanding cancer’s evolutionary origins, researchers can come up with more effective, revolutionary treatments.

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.

How did life begin? It is perhaps the most important question science has ever asked. Over the centuries, the search for an answer has been entwined with some of science's most revolutionary advances, including van Leeuwenhoek's microscope, Darwin's theory of evolution, and Crick and Watson's unveiling of DNA.

A deft mixture of memoir and history, modern biology and behavior, In Search of Memory brings listeners from Kandel's childhood in Nazi-occupied Vienna to the forefront of one of the great scientific endeavors of the 20th century: the search for the biological basis of memory. Nobel Prize winner Eric R. Kandel intertwines the intellectual history of the powerful new science of the mind - a combination of cognitive psychology, neuroscience, and molecular biology - with his own personal quest to understand memory.

How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean B. Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions.

In The Rise of Yeast, Nicholas P. Money argues that we cannot ascribe too much importance to yeast, and that its discovery and controlled use profoundly altered human history. Humans knew what yeast did long before they knew what it was. It was not until Louis Pasteur's experiments in the 1860s that scientists even acknowledged its classification as a fungus. A compelling blend of science, history, and sociology, The Rise of Yeast explores the rich, strange, and utterly symbiotic relationship between people and yeast.

Did NASA really spend millions creating a pen that would write in space? Is chocolate poisonous to dogs? Does stress cause gray hair? These questions are a sample of the urban lore investigated in this audiobook, Fact or Fiction: Science Tackles 58 Popular Myths. Drawing from Scientific American’s “Fact or Fiction” and “Strange But True” columns, we’ve selected 58 of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

We have lost the war on cancer. We spend $150 billion each year treating it, yet - a few innovations notwithstanding - a patient with cancer is as likely to die of it as one was 50 years ago. Most new drugs add mere months to one's life at agonizing physical and financial cost. In The First Cell, Azra Raza offers a searing account of how both medicine and our society (mis)treats cancer, how we can do better, and why we must.

Until recently, microglia were thought to be merely the brain’s housekeepers, helpfully removing damaged cells. But a recent groundbreaking discovery revealed them to be capable of terrifying Jekyll and Hyde behavior. When triggered - and anything that stirs up the immune system in the body can activate microglia - they can morph into destroyers, impacting a wide range of issues from memory problems and anxiety to depression and Alzheimer’s. Under the right circumstances, however, microglia can be coaxed back into being angelic healers.

"It's the animal in us," we often hear when we've been bad. But why not when we're good? Primates and Philosophers tackles this question by exploring the biological foundations of one of humanity's most valued traits: morality.In this provocative book, primatologist Frans de Waal argues that modern-day evolutionary biology takes far too dim a view of the natural world, emphasizing our "selfish" genes.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

In this witty, fact-packed A-Z, Newman takes the listener on a whirlwind tour from caring, sharing vampire bats to intelligent slime mould; from pacifist baboons to Richard Dawkins wrestling naked with his postman; from the invisibility cloak of the Hawaiian bobtail squid to Francis "DNA" Crick's belief that life on Earth began with alien spaceships.

From the Siberian permafrost to balmy California, scientists across the globe are working to resurrect all kinds of extinct animals, from ones that just left us to those that have been gone for many thousands of years. Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to preserve rapidly changing ecosystems. It seems certain that these animals will walk the earth again, but what world will that give us? And is any of this a good idea?

National Geographic Ocean unveils the power and significance of our planet's watery essence: the fundamental importance of the ocean in shaping Earth's climate and chemistry, as well as its vital role in supporting a multitude of life-forms, including our own human race. World-renowned oceanographer Sylvia Earle guides listeners with her lyrical style and inspiring wisdom, describing the evolution, beauty, and impact of our ocean; the challenges it faces, such as climate change, plastic, and overfishing; and the myriad ways we can help protect it.

Since the dawn of humankind, mental illness has been one of our greatest causes of suffering as a species. But for the majority of our history, its causes have remained a mystery. Professor Karl Deisseroth shares his breakthrough discovery, optogenetics, a biological technique that allows us to decipher the brain's inner workings using light. With moving and revelatory stories from both personal and professional experience, he reveals what mental illnesses really are, why we suffer from them and the unexpected role they have played in our evolution.

Vor 100.000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70.000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens.

Throughout the ages, human beings have had a profound fascination with the natural world. It has influenced all aspects of our civilisation, from science and religion to music, art, literature and film. These 12 episodes, taken from Radio 4's epic series Natural Histories, find presenter Brett Westwood exploring two major groups of animals - fish, who have lived on Earth for over 450 million years, and invertebrates, who make up 97 percent of all species worldwide - to find out how our perception and representation of them has changed over time.

Since the discovery of DNA, scientists have believed that genes are fixed entities that cannot be changed by environment - we inherit them, pass them on to our children and take them with us when we die. Professor Tim Spector reveals how the latest genetic research and his own pioneering studies on epigenetics are rewriting everything we thought we knew about genes, identity and evolution.

First published more than 50 years ago, this award-winning classic brings Rachel Carson's unique vision to a new generation of listeners. The Sense of Wonder is Carson's intimate account of adventures with her young nephew, Roger, as they enjoy walks along the rocky coast of Maine and through dense forests and open fields, observing wildlife, strange plants, moonlight, and storm clouds, and listening to the "living music" of insects in the underbrush.

For most of us, the only thing we know about flies is that they're annoying, and our usual reaction is to try to kill them. In Super Fly, the myth-busting biologist Jonathan Balcombe shows the order Diptera in all of its diversity, illustrating the essential role that flies play in every ecosystem in the world as pollinators, waste-disposers, predators, and food source; and how flies continue to reshape our understanding of evolution.
