At the southernmost tip of South Africa, where fresh and salt water collide, a tiny seahorse appears to levitate. Seahorses are the ocean’s slowest swimmers, but they have one of the world’s fastest muscle contractions, using it to suction up their prey. In this episode, we meander through eelgrass with a male Knysna seahorse as he twines tails with his partner, changes color to match the sand, and even gives birth to a brood of tiny seahorses.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

Stephen Fry travels into the most remarkable place we know - our brain. The organ of knowledge and the one we know least about. Over 12 episodes Stephen explores just how much we’ve learned about this mysterious structure in recent years and tries to answer some of the most difficult questions that remain. To do this, we relay the discoveries and stories of neuroscientists, psychologists, anthropologists and even philosophers, to add illumination and perspective as we travel. Each episode will be full of brainy stories: some shocking, some thrilling, some scarcely believable.

Animal scientists have long considered domestic livestock to be too dumb to know how to eat right, but the lifetime research of animal behaviorist Fred Provenza and his colleagues has debunked this myth. Their work shows that when given a choice of natural foods, livestock have an astoundingly refined palate, nibbling through the day on as many as fifty kinds of grasses, forbs, and shrubs to meet their nutritional needs with remarkable precision.

Wissensdurst erlischt nicht. Das beweist die bereits 6. Staffel "Sag mal, du als Physiker". Denn unsere Welt hält immer noch so viele spannende Fragen für unsere Lieblingsphysiker bereit: Wie löscht man eigentlich ein Feuer? Warum wird Brot manchmal mehr im Mund? Wie kühlt man sich in tropischen Nächten am besten runter? Und wie misst man eigentlich Gravitationswellen?

Where do we come from? How did our ancestors settle this planet? How did the great historic civilizations of the world develop? How does a past so shadowy that it has to be painstakingly reconstructed from fragmentary, largely unwritten records nonetheless make us who and what we are?

These 36 lectures bring you the answers that the latest scientific and archaeological research and theorizing suggest about human origins, how populations developed, and the ways in which civilizations spread throughout the globe.

Feeling stressed? You're not alone. Stress is an inherent aspect of life that can have tremendous negative effects on your mental and physical health. This makes coping with stress a critical part of how well we live.Once you understand the inner workings of your stress response system, you'll possess powerful knowledge that will help you understand and better deal with this common aspect of your busy life.

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.

Your nervous system is you. All the thoughts, perceptions, moods, passions, and dreams that make you an active, sentient being are the work of this amazing network of cells. For many centuries, people knew this was true. But no one was sure how it happened. Now, thanks to the exciting new field of neuroscience, we can chart the workings of the brain and the rest of the nervous system in remarkable detail to explain how neurons, synapses, neurotransmitters, and other biological processes produce all the experiences of everyday life, in every stage of life.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

Red pandas have thick bushy ringed tails like raccoons, but they aren’t related to panda bears or raccoons—in fact, they have no close relatives anywhere on Earth. In this episode, we wander the Himalayas with a red panda and her cubs as they munch on bamboo, practice walking in the treetops, and settle in to nap together as the first snowfall of the year covers their forest home.

Was passiert, wenn physikalischer Wissensdurst und begeisterte Wissenschaftler aufeinandertreffen? Richtig, es gibt sehr viele Fragen - und dieser Original Podcast findet klare Antworten. Unsere zwei Lieblingsphysiker und ihr immer noch wissbegieriger Fragensteller dringen weiter in die rätselhaften Zusammenhänge des Alltags vor. Hören Sie, wie sich aus scheinbar Unerklärlichem verständliche Zusammenhänge erschließen.

Sir Alexander Fleming (August 6, 1881 - March 11, 1955) was a Scottish biologist, pharmacologist and botanist. He wrote many articles on bacteriology, immunology, and chemotherapy. His best-known discoveries are the enzyme substance lysozyme in 1923, and the anitbiotic substance penicillin from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain. This audiobook is from a 1950 talk he gave on the development of antibiotics.

What foods did the human body evolve to eat, and why? How does the food we eat affect our genes and our minds? What foods are (and aren't) optimal for our everyday health? How can we use cutting-edge science to end world hunger? In these 36 lectures, get eye-opening answers to these and other perplexing questions about the evolution of the human diet and its relationship to our bodies.

California’s coast redwoods are Earth's tallest living beings, some reaching more than 350 feet high. They can also live for more than 2,000 years, outlasting entire civilizations. In this episode, we spend an evening with an ancient tree. Below ground, its roots tap into a forest-wide network; above ground, its branches harbor life in its many forms.

In these 24 lectures, The Great Courses teams up with the Smithsonian’s National Zoo and Conservation Biology Institute, to take you behind the scenes of the animal world. Dr. Moore has crafted a wonderful introduction to zoology that brings you up close and personal with a breathtaking variety of animal species through the eyes of a trained zoologist.

Charles Darwin's theory of organic evolution-the idea that life on earth is the product of purely natural causes, not the hand of God-set off shock waves that continue to reverberate through Western society, and especially the United States. What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? These 12 eye-opening lectures are an examination of the varied elements that so often make this science the object of strong sentiments and heated debate.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Right this minute, your body is carrying roughly 38 trillion microbial cells along with it—and in the vast majority of cases, you couldn’t live without them. On top of that, you harbor around 380 trillion viruses, most of which are either beneficial or benign. The Hidden Power of Microbes draws back the curtain on this vast microworld in 24 half-hour lectures delivered by acclaimed science communicator Dr. Melissa Booth, research scientist, professor, and Founder and Principal of The Science Communicator, devoted to training scientists to tell accurate, compelling stories about their fields.

When are we responsible for our own actions, and when are we in the grip of biological forces beyond our control? What determines who we fall in love with? The intensity of our spiritual lives? The degree of our aggressive impulses? These questions fall into the scientific province of behavioral biology, the field that explores interactions between the brain, mind, body, and environment that have a surprising influence on how we behave.
