Siamo abituati a concepire la Storia come il susseguirsi sanguinoso di imperi e dinastie. Ma il cammino dell'uomo può essere studiato anche in ambiti specifici del suo ingegno - nell'arte, nella filosofia o nelle scienze. Questo audiolibro propone una chiave molto stimolante attraverso cui "ricapitolare" la storia dell'umanità: quella che vede l'essenza del nostro genere nell'"essere artefice". Perché, a pensarci bene, dietro ogni passo dell'uomo c'è sempre un'invenzione o un manufatto che ha avuto nei secoli imprevedibili sviluppi.

Il 27 dicembre 1831 un brigantino inglese, la Beagle, salpa da Devonport, al comando del capitano Fitz Roy, con a bordo Charles Darwin, a quell'epoca ventiduenne. Scopo della spedizione era completare il rilevamento della Patagonia e della Terra del Fuoco, ispezionare le coste del Cile, del Perù e di alcune isole del Pacifico ed eseguire una serie di misure di longitudine attorno al mondo.

After seeing his own cells used to grow clumps of new neurons - essentially mini-brains - Philip Ball begins to examine the concepts of identity and consciousness. Delving into humanity's deep evolutionary past to look at how complex creatures like us emerged from single-celled life, he offers a new perspective on how humans think about ourselves.

Humans have kept honey bees in hives for millennia, yet only in recent decades have biologists begun to investigate how these industrious insects live in the wild. The Lives of Bees is Thomas Seeley’s captivating story of what scientists are learning about the behavior, social life, and survival strategies of honey bees living outside the beekeeper’s hive - and how wild honey bees may hold the key to reversing the alarming die-off of the planet’s managed honey bee populations.

Since the dawn of time, humans have worshipped the sun. And with good reason. Our biology is set up to work in partnership with the sun. From our sleep cycles to our immune systems and our mental health, access to sunlight is crucial for living a happy and fulfilling life. New research suggests that our sun exposure over a lifetime - even before we were born - may shape our risk of developing a range of different illnesses, from depression to diabetes. Chasing the Sun explores the extraordinary significance of sunlight.

The world's largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms. For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve.

A journey into the weird, wonderful and truly astonishing lives of the small but mighty creatures who keep the world turning. Out of sight, underfoot, unseen beyond fleeting scuttles or darting flights, insects occupy a hidden world, yet are essential to sustaining life on earth. Insects influence our ecosystem like a ripple effect on water. They arrived when life first moved to dry land, they preceded – and survived – the dinosaurs, they outnumber the grains of sand on all the world’s beaches, and they will be here long after us.

There's so much we don't know about what lies deep beneath the ocean's surface - and the time to find out is growing increasingly precious.... Professor Alex Rogers is one of the world's leading experts in marine biology and oceanology and has spent his life studying the deep ocean - and in particular the impact of human activity on the ecosystems of the oceans. In this timely, galvanising and fascinating book, Professor Rogers offers a fundamentally optimistic view of humanity's relationship with the oceans - and also a very personal account of his own interaction with the seas.

Cosa sono le cellule staminali? E perché molti scienziati non si accontentano di studiare le staminali adulte e continuano ad interessarsi alle embrionali? Considerate da molti una speranza per risolvere patologie incurabili, queste cellule sono da qualche anno uno dei temi caldi del dibattito pubblico, poiché le loro potenzialità applicative rappresentano un terreno di scontro tra diverse concezioni etiche, giuridiche e religiose.

Choosing a profession begins with imagining yourself in a career. Now New York Times best-selling author Virginia Morell dives into the adventures of a marine biologist team, allowing a much needed, in-depth look into the field. Becoming a Marine Biologist explores how successful marine biologists curated their careers and what they suggest to young people today who feel called to protect our oceans by studying the sea and its inhabitants.

Max Delbrück, geboren am 4. September 1906 in Berlin, gestorben am 10. März 1981 in Pasadena. Physiker und Biologe, Begründer der Molekulargenetik, 1969 ausgezeichnet mit dem Nobelpreis für Medizin und Physiologie, ist hier in Originaltonaufnahmen als Vortragender, Interviewpartner und Sänger zu hören.

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, authors Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds and how sexual conflict is resolved in different species.

A magnificently reported and soulfully crafted exploration of the human immune system - the key to health and wellness, life and death. An epic, first-of-its-kind audiobook, entwining leading-edge scientific discovery with the intimate stories of four individual lives, by the Pulitzer Prize-winning New York Times journalist.

The landscape of cancer treatment and prevention is a vastly different place than it was even a decade ago. Thanks to a relatively new focus on molecular medicine, researchers are gaining a deeper understanding of the mechanisms involved in the disease, poising them on the brink of huge breakthroughs. What Science Knows About Cancer reports from the front lines of the war on cancer with a clear and scientifically precise - yet thoroughly accessible - guide to how the disease develops, thrives, and can potentially be conquered.

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.

Dame Sue Black is an internationally renowned forensic anthropologist and human anatomist. She has lived her life eye to eye with the Grim Reaper, and she writes vividly about it in this book, which is part primer on the basics of identifying human remains, part frank memoir of a woman whose first paying job as a schoolgirl was to apprentice in a butcher shop, and part no-nonsense but deeply humane introduction to the reality of death in our lives. It is a treat for CSI junkies, murder mystery and thriller fans, and anyone seeking a clear-eyed guide to a subject that touches us all.

Epidemiologist Steffanie Strathdee and her husband, psychologist Tom Patterson, were vacationing in Egypt when Tom came down with a stomach bug. What at first seemed like a case of food poisoning quickly turned critical, and by the time Tom had been transferred via emergency medevac to the world-class medical center at UC San Diego, where both he and Steffanie worked, blood work revealed why modern medicine was failing: Tom was fighting one of the most dangerous, antibiotic-resistant bacteria in the world.

Quando e dove è iniziata la vita? E a cosa somigliavano le prime forme di vita? Interrogativi che l'uomo si pone da sempre, per i quali, pur in mancanza di risposte definitive, si possono avanzare alcune ipotesi. Come quella che colloca l'origine della vita intorno a 3,8 miliardi di anni fa, in un contesto riconducibile a uno di questi ambienti: brodo primordiale, campi geotermali, siti di impatto meteoritico. Certo è che le tessere del più grande e affascinante dei puzzle restano RNA, amminoacidi, protogeni, protocellule.
