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 Podcasts 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.

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.

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.

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.

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.

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.

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.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

Quali sono i più incredibili meccanismi della vita? Quali tecnologie ci hanno portato alle scoperte? Come fanno scoperte vecchie di cento anni ad influenzare ancora la nostra vita e le nuove tecnologie? In "Dieci! Biologia" Giuliano, Simone e Ilaria vi accompagnano nel mondo dei viventi cercando di capire come funzionano e quali sono state le intuizioni geniali che hanno cambiato per sempre il modo in cui guardiamo il mondo che ci circonda. In collaborazione con Scientificast.it.

North Ronaldsay sheep have been roaming the shores of a Scottish isle for centuries. They outnumber people there by more than twenty to one. While most sheep graze in fields, the North Ronaldsay are a breed apart: they forage seaweed on the rocky beach. In this episode, we follow a lamb as she crosses the island’s ancient stone dyke and sees the ocean for the first time.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Epigenetics is the science of living DNA, charting the chemical pathways that spur DNA into action by turning genes on and off. While the Human Genome Project of the early 2000s was hailed as the key to understanding human heredity and disease, that historic effort was just the beginning. It has taken epigenetics to fill in the picture, explaining how the fixed code of our genome is implemented in countless living processes.

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.

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.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.

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.

Topics explored in this dialogue include: how you can address the greatest challenge of our times, the role of the arts in deep ecology, how the shift from linear thinking to systems thinking in the sciences affects us now and in the future, understanding the complexity of living systems and life itself, why creativity is the driving force of evolution, what religion and deep ecology have in common, what's really behind the information age, and the mathematics of complexity.

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.

"Terra in vista - La scienza e la tecnologia spiegate a mio figlio" è un programma di Radio24 di divulgazione scientifica per ragazzi, condotto da Federico Taddia e dal filosofo della scienza Telmo Pievani. Si può dire che le piante siano capaci di parlare? E cosa dicono? Quale linguaggio usano? Con chi comunicano e perché lo fanno? Ospite della puntata è Francesca Rapparini, ricercatrice presso l'Istituto Ibimet del CNR. Come sempre non può mancare l'esperimento proposto da Agnese Sonato, caporedattrice della rivista scientifica per bambini PLaNCK.
