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.

In 1966, Isaac Asimov and Theodosius Dobzhansky wrote The Genetic Effects of Radiation as a public information resource for the US Atomic Energy Commission. In Asimov's typically incisive and easy-to-understand style, the pair presents an overview of genetics, and how inherited traits can be influenced by external factors, including radiation, both environmental and man-made.

The great scientists Louis Pasteur (1822-1893) and Joseph Lister (1827-1912) revolutionized medical practice in the 19th century. Pasteur's discovery of the cause of fermentation formed the basis of modern germ theory while Lister developed antiseptic surgical methods based on that. The book contains a description of the theory, and accounts of their work and experiments.

This is the first in a series of "mini" audiobooks on scientists who have provided us with great insights into how nature works. The first audiobook is on Charles Darwin's understanding of natural selection as excerpted from his classic tome On the Origin of Species. Includes a brief introduction by Professor David Christopher Lane, PhD.

When Karin enters a high-ranked university to start her PhD she is brimming with hope and positively overflowing with grit determination to prove she is worthy. After all, she knows that only the extraordinarily learned and the astonishingly intelligent ever hold chairs and professorships. She knows researchers are idealists yearning to enrich the stock of human knowledge. She knows university is the apotheosis of civilised culture... She knows very little.

Who Was Henrietta Lacks? On a bright day of August 1st, in the year of 1920, Eliza and Johnny Pleasant brought forth a girl Loretta Pleasant, who’s name was later on changed to Henrietta Lacks for reasons unknown to the family. As she grew up, she was given the nickname Hennie.

Nachdem sich die moderne Hirnforschung in den letzten zwanzig Jahren rasant entwickelte, hat auch das Interesse an ihren Resultaten zugenommen. Was will der Mensch? Entscheidet er selbst? Oder ist er nur das Opfer chemischer und neuronaler Affekte? Das sind spannende Fragen, besonders für Werbung und Kommunikation. Wie nimmt der Mensch wahr? Und vor allem: Was nimmt er auf? Werner T. Fuchs beschäftigt sich seit Jahren mit der Umsetzung moderner Hirnforschung ins Marketing. Seine These - inzwischen von der Hirnforschung untermauert - lautet: Der Mensch lernt durch Geschichten. Wer diese Erkenntnis in die Praxis einfließen lässt, wird sein Gegenüber besser erreichen. Fuchs hat zwölf leicht zu verstehende, unterhaltsame "Werkzeuge" kreiert, die helfen, Kommunikation grundsätzlich neu zu verstehen und auf die Arbeitsweise des Gehirns abzustimmen.

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?

How smart machines are transforming us all - and what we should do about it. The smart machines revolution is reshaping our lives and our societies. Here, Nigel Shadbolt (one of Britain’s leading authorities on artificial intelligence) and Roger Hampson dispel terror, confusion and misconception. We are not about to be elbowed aside by a rebel army of superintelligent robots of our own creation. We were using tools before we became Homo sapiens and will continue to control them. How we exercise that control - in our private lives, in employment, in politics - and make the best of the wonderful opportunities will determine our collective future well-being.

Crave answers? A Feast of Science demystifies the chemistry of everyday life, serving up practical knowledge to both inform and entertain. Guaranteed to satiate your hunger for palatable and relevant scientific information, Dr. Joe Schwarcz proves that "chemical" is not necessarily synonymous with "toxic".

Eminent ecologist Jeremy B. C. Jackson and award-winning journalist Steve Chapple traveled the length of the Mississippi River interviewing farmers, fishermen, scientists, and policymakers to better understand the mounting environmental problems ravaging the United States. Along their journey, which quickly expanded to California, Florida, and New York, the pair uncovered surprising and profound connections between ecological systems and environmental crises across the country.

By 2030, experts predict two-thirds of people living on this planet will not have enough water, a situation expected to result in the deaths of millions and an unprecedented rise in military conflicts. Can we as individuals hope to reverse these dire predictions? Award-winning author and water activist Florencia Ramirez believes we can if our conservation efforts focus on the 70 percent of freshwater flowing to the fields and ranches that grow our food. Eat Less Water takes the listener on a journey to meet America's food producers growing food with less water.

What are African elephants? How different are they from Asian elephants? What do they look like, and what do they like to do? What makes male and female elephants different from each other? These and more questions will be answered with the help of this audiobook. Elephants are big and somewhat scary, especially for young kids. But with this audiobook, kids will surely have fun learning about these big animals and will be taught to appreciate them a lot more.

In order to bring its origin to light, Rebecca Skloot weaves together several narrative threads. One is primarily focused on Henrietta Lacks, the woman who, without her knowledge, became central to 20th century biomedical research. Another is the birth of modern biomedical research itself, and its roots in the American eugenics movement. Finally, there is the impact of this research, both of the Lacks Family and on society at large. Skloot divides the book into 3 parts: Life, Death, and Immortality.

Race has provided the rationale and excuse for some of the worst atrocities in human history. Yet, according to many biologists, physical anthropologists, and geneticists, there is no valid scientific justification for the concept of race. To be more precise, although there is clearly some physical basis for the variations that underlie perceptions of race, clear boundaries among "races" remain highly elusive from a purely biological standpoint.

Since the birth of civilization, human beings have manipulated other life-forms. We have selectively bred plants and animals for thousands of years to maximize agricultural production and cater to our tastes in pets. The observation of the creation of artificial animal and plant variants was a key stimulant for Charles Darwin's theory of evolution. The ability to directly engineer the genomes of organisms first became possible in the 1970s, when the gene for human insulin was introduced into bacteria.

In Long Hops, physicist Mark Denny explains, in a clear, conversational style, the science of bird migration - from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights.

Evidence as to Man's Place in Nature was written in 1863 by Thomas Henry Huxley. In this work, Huxley presents evidence for the evolution of man and ape from a common ancestor. Evidence as to Man's Place in Nature was the first book in history devoted to the topic of human evolution, and it discussed this theory in light of anatomical and other evidence.
