When a good friend with a severe illness wrote, asking if he might have his “green burial” at Bernd Heinrich’s hunting camp in Maine, it inspired the acclaimed biologist to investigate a subject that had long fascinated him. How exactly does the animal world deal with the flip side of the life cycle? And what are the lessons, ecological to spiritual, raised by a close look at how the animal world renews itself?

In questo audiolibro viene affrontato il genoma umano, analizzando scientificamente le sue caratteristiche: dna, nucleo, citoplasma, cellula, organuli e mitocondri. Buona ascolto!

Analyzing brainwaves, the imperceptible waves of electricity surging across your scalp, has been possible for nearly a century. But only now are neuroscientists becoming aware of the wealth of information brainwaves hold about a person’s life, thoughts, and future health. From the moment a reclusive German doctor discovered waves of electricity radiating from the heads of his patients in the 1920s, brainwaves have sparked astonishment and intrigue, yet the significance of the discovery and its momentous implications have been poorly understood.

Taking us on an incredible journey across centuries and galaxies, accompanied by his characteristic wit, Professor Luke O’Neill explains how it all began, how it will all end and everything in between. Listeners will benefit from Luke’s insatiable curiosity for life when they dive into this ultimate journey through life and death. Among other fascinating facts, you’ll discover the science behind how we got to be so smart, why sex with a caveman was a good idea, the science of finding love, why we follow religions and how robots will become part of everyday life.

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.

How four tools enabled humanity to control its destiny What enabled us to go from simple stone tools to smartphones? How did bands of hunter-gatherers evolve into multinational empires? Listeners of Sapiens will say a cognitive revolution - a dramatic evolutionary change that altered our brains, turning primitive humans into modern ones - caused a cultural explosion. In Transcendence, Gaia Vince argues instead that modern humans are the product of a nuanced coevolution of our genes, environment, and culture that goes back into deep time.

Understanding the Cell is a college introductory-level audiobook in a conversational manner. Within each section key words and concepts are introduced, discussed, and then reviewed. The audio format allows students to make the most of their time by giving them the freedom to study by listening.

Por meio de fotografias subaquáticas incríveis, de altíssima qualidade, e relatos exclusivos, Gabriel Ganme, instrutor de mergulho há mais de trinta anos, apresenta neste audiolivro as mais variadas espécies de tubarões, compartilhando suas divertidas e curiosas experiências mergulhando com esses animais. 'Assassino dos mares' ou 'terror dos oceanos' são apenas algumas das injustas alcunhas atribuídas a essas criaturas maravilhosas que possuem importância incontestável para o equilíbrio e a saúde dos ecossistemas marinhos.

From birthdays to birth rates to how we perceive the passing of time, mathematical patterns shape our lives. But for those of us who left math behind in high school, the numbers and figures hurled at us as we go about our days can sometimes leave us scratching our heads, feeling as if we're fumbling through a mathematical minefield.

Elegantly written and deeply grounded in personal experience - works by Oliver Sacks come to mind - Physical Intelligence gives us a clear, illuminating examination of the intricate, mutually responsive relationship between the mind and the body as they engage (or don’t engage) in all manner of physical action. Ever wonder why you don’t walk into walls or off cliffs? How you decide if you can drive through a snowstorm? How high you are willing to climb up a ladder to change a lightbulb?

In this groundbreaking book, Dr. Mosley takes us on a revelatory journey through the gut, showing how junk food and overuse of antibiotics have wiped out many good gut bacteria, leading to a modern plague of allergies, food intolerances and obesity. Drawing from the latest cutting-edge research, Dr. Mosley provides scientifically proven ways to control your cravings, boost your mood and lose weight by encouraging a more diverse microbiome and increasing the good bacteria that keep you healthy.

Depuis l'apparition d'homo sapiens et la révolution cognitive il y a 50 000 ans, les capacités de notre espèce à comprendre et modifier son environnement paraissent sans limites. Un seul mystère reste inviolé : celui de la nature humaine et de sa civilisation. Ce que nous sommes vraiment, pourquoi notre espèce fait ce qu'elle fait, défie toute explication rationnelle.

For over three decades, Ray Kurzweil has been one of the most respected and provocative advocates of the role of technology in our future. In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: The union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.

Mummie del ghiaccio, delle cripte e delle catacombe, arrivate fino a noi dalle Ande alla Cina. I diversi processi di mummificazione, a cui sono stati sottoposti - per citare tre casi famosi - Ötzi, Tutankhamon, Evita Perón, ci permettono di affondare lo sguardo nelle condizioni di vita degli uomini del passato. Grazie ai metodi più avanzati della bioarcheologia molecolare, inoltre, si può far luce sulle patologie antiche e trarne informazioni importanti sull'evoluzione di alcune malattie del nostro tempo.

Vi går gennem hele livet i en og samme krop, og alligevel ved de fleste af os stort set intet om, hvordan vores krop fungerer, og hvad der sker inden i os. Dette gør den formidable videnskabsformidler Bill Bryson, forfatter til bl.a. bestselleren "En kort historie om næsten alt", noget ved. I "Kroppen - en guide for indehavere" tager han os med på en dybt fascinerende rejse fra top til tå og anskueliggør det vidunder, vores legeme er.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

On the Origin of Species (1859) by Charles Darwin is a work of scientific literature considered to be the foundation of evolutionary biology. The book introduced the theory that populations evolve over the course of generations through a process of natural selection, backed by a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. The evidence was gathered on the Beagle expedition in the 1830s and the author’s subsequent findings from research, correspondence, and experimentation.

Nano Comes to Life opens a window onto the nanoscale - the infinitesimal realm of proteins and DNA where physics and cellular and molecular biology meet - and introduces listeners to the rapidly evolving nanotechnologies that are allowing us to manipulate the very building blocks of life. Sonia Contera gives an insider's perspective on this new frontier, revealing how nanotechnology enables a new kind of multidisciplinary science that is poised to give us control over our own biology, our health, and our lives.

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.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.
