De plus en plus, des percées déroutantes redéfinissent la biologie. Le fondateur de la chaîne YouTube DirtyBiology s'en fait l'écho et propose des informations impertinentes et instructives sur les gènes, la vie ou l'évolution.

Sharks are some of the most fascinating and ecologically important, yet most threatened and misunderstood animals on Earth. More often feared than revered, their role as predators of the deep has earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us—they’re in danger from us. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman urges us to overcome our misconceptions and embrace sharks as the imperiled and elegant ocean guardians they really are.

By the time a baby is born, its brain is equipped with billions of intricately crafted neurons wired together through trillions of interconnections to form a compact and breathtakingly efficient supercomputer. Zero to Birth takes you on an extraordinary journey to the very edge of creation, from the moment of an egg's fertilization through each step of a human brain's development in the womb—and even a little beyond. As W. A. Harris guides you through the process of how the brain is built, he takes up the biggest questions that scientists have asked about the developing brain.

The MRC Laboratory of Molecular Biology (LMB) in Cambridge, UK is a world-leading scientific institution. This book, by LMB alumna Kathy Weston, is a collective portrait of women scientists who, as staff members, visitors, and trainees, helped build the LMB’s reputation as a powerhouse of science, often going on to stellar careers at other outstanding institutions around the world. Combining narrative history with interview transcripts and personal reminiscence, Weston’s book describes the career accomplishments of these successful scientists.

For decades, biology has been dominated by information—the power of genes. Yet in terms of information there is no difference between a living cell and one that died a moment ago. What really animates cells and sets them apart from non-living matter? This question goes back to the flawed geniuses and heroic origins of modern biology. The answer could turn our picture of life on Earth upside down.

Die CRISPR-Methode und die Zukunft der Medizin. Was macht die Natur, wenn ein neuer Feind auftaucht? Sie findet eine neue Strategie. Wenn eine Bakterie von einem Virus attackiert wird, verteidigt sie sich beispielsweise, indem sie ihre genetische Struktur ändert. Doch wie können diese Mechanismen nachgewiesen werden? Und welchen Nutzen hat dieses Wissen für die Medizin? Der Amerikanerin Jennifer Doudna und der Französin Emmanuelle Charpentier sind bahnbrechende Erkenntnisse im Bereich der Biochemie gelungen.

Verglichen mit anderen Erdbewohnern dauert ein Menschenleben nur einen Wimpernschlag: Kalifornische Redwoods können fünftausend Jahre alt werden, einige Quallenarten kehren ihren Alterungsprozess um und manche Bakterien sind sogar unsterblich. Molekularbiologe Nicklas Brendborg nimmt die Leser:innen mit in die entlegensten Winkel der Welt und die modernsten Forschungslabors; unterwegs zu den ältesten Menschen, zu Zombiezellen und zu Experimenten, die unsere grundlegenden Vorstellungen vom Leben auf den Kopf stellen.

In a world where irrigation water is contaminated by run-off from cattle feedlots and where food processors cut corners, the food preparation skills we learned from our parents and grandparents are no longer good enough to keep us safe.

As she traces three timber poaching cases, she introduces us to tree poachers, law enforcement, forensic wood specialists, the enigmatic residents of former logging communities, environmental activists, international timber cartels, and indigenous communities along the way.

If you are at all interested in life on our planet, then you need to know about insects. They are the most successful group of animals ever to have lived on Earth. Making up three-quarters of all animal species, insects conquered the planet long ago. They were among the very first animals to appear on land and were the first to take to the air. Their total biomass is at least 10 times that of all humans and our livestock combined. Join Dr. George McGavin on an exciting audio journey to help us understand the fascinating world of insects.

Whether it's in a cockpit at takeoff or the planning of an offensive war, a romantic relationship or a dispute at the office, there are many opportunities to lie and self-deceive - but deceit and self-deception carry the costs of being alienated from reality and can lead to disaster. So why does deception play such a prominent role in our everyday lives? In short, why do we deceive?

In forests, fields and even gardens, there is a constant exchange of information going on. Animals and plants must communicate with one another to survive, but they also tell lies, set traps, talk to themselves and speak to each other in a variety of unexpected ways. In Nature Is Never Silent, behavioural biologist Madlen Ziege reveals the fascinating world of nonhuman communication. In charming, humorous and accessible prose, she shows how nature’s language can help us to understand our own place in the natural world a little better.

Inside our heads we carry around an infinite and endlessly unfolding map of the world. Navigation is one of the most ancient neural abilities we have - older than language. In Dark and Magical Places, Christopher Kemp embarks on a journey to discover the remarkable extent of what our minds can do.

From the cup of coffee that jump-starts the day to dangerously addictive drugs, the recreational use of plants with psychoactive properties has a long history among humans. But, as with many things, it turns out that other animals got there first. From parrots to primates, consuming medicinal chemicals is an instinctive behavior that helps countless organisms fight infection and treat disease. But the similarities don't end there: Like us, many creatures also consume substances that have no apparent benefit...except for inducing intoxication.

Bevor Sie in dieses Buch eintauchen, lehnen Sie sich noch einmal zurück, atmen Sie tief ein und werfen Sie einen Blick aus dem Fenster. Was sehen Sie? Sehen Sie Schmetterlinge, deren bunte Flügel im Sonnenlicht strahlen? Beobachten Sie vielleicht einen Vogel seine Eier ausbrüten? Blicken Sie auf Bienen, die gerade Blumen bestäuben oder regnet es vielleicht? Vermutlich ist der Blick aus dem Fenster für Sie bereits ein vertrauter Anblick und doch können Sie mir glauben, wenn ich Ihnen sage, dass genau dieser vertraute Anblick nach dem Lesen dieses Buches ein anderer sein wird.

This will explain what we mean by stem cell therapy. This was designed to be a presentation to an audience of mainly healthcare providers to interest them in participating in clinical trials on an instrument that obtains the product. It introduces what stem cell therapy is, what it contains, and how it relates to stem cells. The general population will get a good idea as to what we mean when we talk about regenerative treatment using stem cells.

Dieses Hörbuch macht die komplexe Entstehung des Lebens auf unserem Planeten erstmals für alle verständlich. Dabei stand das Leben auf der Erde schon mehrfach kurz vor der Auslöschung. Es gab zwei Millionen Jahre dauernde Vulkanausbrüche und mehrfach schwere Asteroideneinschläge. Katastrophen, ohne die allerdings etwa die Ausbreitung der Säugetiere nicht möglich gewesen wäre. Henry Gee schildert unterhaltsam und anschaulich, wie sich das Leben immer wieder durchsetzte.
