Extrêmement complexe, notre cerveau livre peu à peu ses mystères grâce aux recherches récentes. On connaît mieux aujourd'hui l'ensemble du système nerveux, la structure du cerveau, les éléments qui le composent, et, contrairement aux idées reçues, ses indéniables capacités d'évolution, voire de régénération. Grand régulateur des fonctions vitales (respiration ou sommeil), siège des fonctions évoluées (langage ou pensée), le cerveau peut être victime de dérèglements dramatiques.

This gives a brief and quick overview of evolutionary theories of the origins of early life at the microscopic levels and the view of how organic substances can come from inorganic substances.

Physik war lange das meistgehasste Fach in der Schule, und Physiker galten nicht gerade als besonders sexy...

"Was macht denn den Menschen aus, aus Sicht der Neurobiologie heute - nicht nur gegenüber Außerirdischen, sondern auch in Abgrenzung tierischer Lebensformen..."

DNA serves as the basic instruction manual for life. In this installment, we look at the way in which DNA is structured, replicated, and how it is packaged into such a small area. This will provide the basic understanding of how genes are structured in an easy to understand way.

Los insectos son el grupo más numeroso del reino animal. Información general sobre las abejas. La colmena: características, zánganos, abejas reina, obreras, funciones. Las abejas y el ecosistema.

This serves as the second book in the Basics of Biology series. In this segment, the functions of membranes are explored. With regards to fully understanding biological organisms, the cell membrane is essential to developing an understanding of how cell function to control the substance that enter and exit them along with they way in which they interact with their environment.

The environment can cause - and cure - cancer! Out of the labs of the prestigious Pasteur Institute came decades of research that unlocked the mystery of cancer at the DNA level. But we're only just now finding out about it.

Why do organisms grow old and die? What are the theories of aging? Does the Free Radical Theory of Aging still stack up? How do cells decide when to divide, differentiate or die? What factors accelerate the aging process? This essay takes a look at these issues and would thus be useful to students who want to know more about the processes that control cell death. The essay also documents the more extreme measures that some people have taken in the pursuit of eternal youth.

Thousands of people just like you have been raising bees and making their own honey right in their own backyards. Learn the ins and outs of the joy of keeping bees in this information packed beekeeping 101 guide.

The human reaction to insects is neither purely biological nor simply cultural. And no one reacts to insects with indifference. Insects frighten, disgust, and fascinate us. Jeff Lockwood explores this phenomenon through evolutionary science, human history, and contemporary psychology, as well as a debilitating bout with entomophobia in his work as an entomologist. Exploring the nature of anxiety and phobia, Lockwood explores the lively debate about how much of our fear of insects can be attributed to ancestral predisposition for our own survival and how much is learned through individual experiences.

The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behavior and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes.

The blackbird is one of the most familiar of all British birds and its song is a great favourite. Enjoy the beautiful melodies created by this much-loved songbird in the British Library's new collection of recordings, which reveal the extraordinary virtuosity, splendour, and magic of its song. From the poet Edward Thomas to the Beatles, the blackbird has been an inspiration to writers, composers, and the wider public for many centuries.

Did you know that the CIA once made use of a “spy cat”, or that, although delicious, eating the flesh of an armadillo can give you leprosy? And what about Terry, the small black Cairn Terrier from Kansas who was paid today’s equivalent of $2,000 a week for her work in The Wizard of Oz? Even if you think you have a handle on all things trivia, you're guaranteed a big surprise with Now I Know: Animals.

Did you know that San Diego’s Frozen Zoo is home to preserved DNA samples from over 8,000 endangered or threatened species, or that the tell-tale smell of freshly mowed grass is actually the plant’s version of a distress call? And what about Henrietta Lacks, the “immortal woman” whose cancer cells have been divided and multiplied for research purposes for over 60 years? Even if you think you have a handle on all things trivia, you're guaranteed a big surprise with Now I Know: Science.

Our health care system is crippled by desperate efforts to prevent the inevitable. A third of the national Medicare budget - nearly $175 billion - is spent on the final year of life, and a third of that amount on the final month, often on expensive (and futile) treatments. Such efforts betray a fundamental flaw in how we think about healthcare: we squander resources on hopeless situations, instead of using them to actually improve health.

Outstanding field recordings of songs and calls of 60 species most common to the eastern U.S.: Warblers, Woodpeckers, Flycatchers, Thrushes, Larks, many more.

Noted ornithologist's outstanding field recordings of songs and calls. This set covers 60 birds with several recordings for each.

A classic work examining bird song as both a means of identification and study of behavior. This recording cites 72 species and 51 songs.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.
