“Kernenergie is veilig!”, “Nee, het brengt enorme risico’s met zich mee! En wat te denken van dat afval?!”, “Dat kun je hartstikke veilig opslaan!”, “Maar kernenergie is veel te duur!”, “Nee hoor, en wat als er geen zon en wind is voor doe windmolen en zonnepanelen van jou?!”
Kernenergie is terug van weggeweest. Niet alleen op de politieke agenda - het nieuwe kabinet wil niet minder dan 4 nieuwe centrales gaan bouwen - maar ook in het publieke debat. En dat debat is soms even explosief als de bom waarmee het nucleaire tijdperk begon. Voor- en tegenstanders buitelen over elkaar heen met feiten en verwijten over veiligheid, betaalbaarheid, etc. Althans, ieder kamp zégt feiten te gebruiken en verwijten de ander dat juist niet te doen. Kortom, het is hard tegen hard. Maar wie heeft er nu gelijk? Of kun je die vraag helemaal niet - of niet geheel - beantwoorden? Waar eindigen de feiten en beginnen de meningen? Wanneer verandert ‘weten’ in ‘vinden’ en ‘geloven’?
In Splijtstof duiken wetenschapsjournalist Diederik Jekel en presentator & afgestudeerd cultuurwetenschapper Daan Nieber in het kernenergiedebat om deze vragen te beantwoorden. Zonder een kant te kiezen, dat mag de luisteraar zelf doen. Als bèta (Diederik) en alfa (Daan) kunnen zij zowel uitleggen hoe kernenergie werkt als laten zien hoe het verleden ons denken over deze technologie en onze cultuur hebben beïnvloed. Van kernsplitsing voor dummies en Small Modular Reactors tot de invloed van de Simpsons op de publieke opinie en een nucleaire religie om toekomstige generaties te wijzen op het gevaar van kernafval. Het komt allemaal voorbij.
In elk van de 8 afleveringen staat een onderdeel van het kernenergiedebat centraal. En Diederik en Daan blijven daarvoor niet alleen in de studio. Verschillende afleveringen beginnen op locatie. Zo laat Diederik Daan in aflevering 2 in een werkende onderzoeksreactor kennis maken met de zogenoemde Cherenkov straling, een mysterieuze blauwe gloed die ontstaat bij een nucleaire kettingreactie onderwater. Voor de aflevering over nucleair afval dalen ze naar een Belgisch onderzoekslab 250 meter onder de grond. En de laatste aflevering trappen ze af in Wunderland Kalkar, een extreem dure kerncentrale net over de grens in Duitsland die uiteindelijk nooit in gebruik werd genomen en verbouwd werd tot pretpark. Want hoe voorkomen we straks niet eindigen met vier peperdure pretparken in Borssele, Terneuzen en op de Tweede Maasvlakte?
Door te ontrafelen waar voor- en tegenstanders over botsen, te onderzoeken waar de zekerheid eindigt en onzekerheid begint, kan de luisteraar van Splijtstof uiteindelijk zelf een keuze maken over het nut en de noodzaak van kernenergie. We gaan van kernenergie als ‘splijtstof’ naar stof tot nadenken. En hij/zij/hen kan op feestjes en verjaardagen de blits maken met fijne feitjes, wonderbaarlijke weetjes en fascinerende verhalen.

Amidst the dense forests and rugged landscapes of North America, a remarkable creature roams, often unseen but forever etched in the tapestry of the continent's wilderness: the black bear (Ursus americanus). With their glossy black fur, curious nature, and adaptable spirit, black bears have long captivated the imagination of humans, serving as emblems of the untamed wild and the mysteries that lie within. From the deciduous forests of the eastern United States to the coniferous woodlands of the Pacific Northwest, black bears have carved out a niche as one of the most successful and widespread large mammals in North America. Their story is one of resilience, adaptability, and the enduring power of nature in the face of an ever-changing world. Evolutionary History and Taxonomy Black bears are members of the family Ursidae, which includes eight extant species of bears worldwide. The black bear's lineage can be traced back to the Etruscan bear (Ursus etruscus), which inhabited Europe during the Pliocene epoch, approximately 5.3 to 2.6 million years ago. Over time, the ancestors of modern black bears migrated to North America via the Bering Land Bridge, evolving and adapting to the diverse habitats they encountered. Today, black bears are found throughout much of North America, from Canada to Mexico, and are considered a distinct species from their close relative, the Asiatic black bear (Ursus thibetanus), which inhabits parts of Asia. Within the species Ursus americanus, there are several recognized subspecies, each adapted to the unique ecological conditions of their range. Physical Characteristics and Adaptations Despite their name, black bears exhibit a wide range of coat colors, from jet black to cinnamon, blonde, and even white in the rare Kermode or spirit bear of British Columbia. Adults typically weigh between 200 and 600 pounds (90 to 270 kg), with males being larger than females. They have a stocky build, with a long snout, small eyes, and rounded ears. Black bears possess a number of adaptations that allow them to thrive in their diverse habitats. Their powerful, curved claws enable them to climb trees, dig for food, and defend themselves when necessary. They have an acute sense of smell, which they use to locate food sources and navigate their surroundings. Additionally, their teeth are adapted for an omnivorous diet, with sharp canines for meat and flat molars for grinding plant matter. One of the most remarkable adaptations of black bears is their ability to hibernate during the winter months. By slowing their metabolism and reducing their body temperature, bears can conserve energy and survive on their stored fat reserves for several months. During this time, they do not eat, drink, urinate, or defecate, making hibernation an efficient survival strategy in regions with harsh winters. Habitat and Distribution Black bears are highly adaptable and can thrive in a variety of habitats, from dense forests to open meadows, and from swamps to mountainous terrain. They are found throughout much of North America, with their range extending from Alaska and Canada in the north to Mexico in the south, and from the Atlantic coast to the Pacific. The distribution of black bears is largely determined by the availability of suitable habitat and food sources. They require large expanses of undeveloped land with diverse vegetation and ample opportunities for foraging and denning. As human development continues to encroach on bear habitat, black bears have demonstrated a remarkable ability to coexist with humans, sometimes even thriving in suburban and urban areas where food is readily available. Feeding Ecology and Behavior Black bears are opportunistic omnivores, meaning they eat a wide variety of plant and animal matter depending on what is available in their environment. Their diet varies seasonally and can include berries, nuts, roots, grasses, insects, fish, small mammals, and carrion. In some regions, black bears also rely on human food sources, such as garbage, pet food, and agricultural crops, which can lead to conflicts with people. Throughout the year, black bears undergo significant changes in their feeding behavior to cope with seasonal food availability. In the spring, when food is scarce, bears emerge from hibernation and focus on finding high-protein foods, such as newborn ungulates and early-emerging vegetation. As summer progresses and fruits and nuts become abundant, bears shift their diet to take advantage of these high-calorie food sources, gaining weight rapidly in preparation for winter. Black bears are generally solitary animals, with the exception of mothers and their cubs. They have a hierarchical social structure, with dominant males occupying the most productive habitats and mating with multiple females. Females, in turn, are responsible for rearing their cubs and teaching them the skills they need to survive on their own. Reproduction and Life Cycle Black bears have a unique reproductive strategy known as delayed implantation. Mating occurs in the spring or early summer, but the fertilized egg does not immediately implant in the uterus. Instead, it remains dormant until the fall, when the female's body determines whether she has enough fat reserves to support pregnancy and lactation. If the female is in good condition, the egg will implant, and the cubs will be born in the winter den.
Black bear cubs are born blind, hairless, and weighing less than a pound (0.5 kg). They are entirely dependent on their mother's milk and care for survival. Cubs remain with their mother for about 18 months, learning crucial survival skills such as foraging, climbing, and avoiding predators. After this time, the cubs disperse to establish their own territories, and the mother is ready to mate again. Female black bears typically reach sexual maturity at around 3 to 5 years of age, while males mature slightly later, at 4 to 6 years. The lifespan of black bears in the wild can vary greatly depending on factors such as habitat quality, food availability, and human-related mortality, but they can live up to 30 years or more. Conservation and Human Interaction Black bears have a complex history of interaction with humans, ranging from reverence and cultural significance to persecution and conflict. In many Indigenous cultures across North America, black bears are considered sacred animals, often associated with healing, wisdom, and spiritual power. These traditional ecological knowledge systems have played a vital role in shaping the relationship between bears and people for thousands of years. However, as European colonization and settlement expanded across the continent, black bears increasingly came into conflict with human activities. They were hunted for their meat, fur, and fat, and were often seen as a threat to livestock and crops. Bounty systems and unregulated hunting led to significant declines in black bear populations in many parts of their range. In the 20th century, changing attitudes towards wildlife and the implementation of conservation measures, such as regulated hunting and habitat protection, helped to stabilize and recover many black bear populations. Today, black bears are considered a species of least concern by the International Union for Conservation of Nature (IUCN), with stable or increasing populations in most of their range. Despite this success, black bears still face ongoing challenges, primarily related to human-bear conflicts and habitat loss. As human development continues to expand into bear habitat, encounters between bears and people are becoming more frequent, often resulting in property damage, injury, or even death for both bears and humans. Managing these conflicts through education, bear-proof waste management, and land-use planning is crucial for ensuring the long-term coexistence of black bears and people. Looking to the future, the conservation of black bears will require a multifaceted approach that addresses the complex social, ecological, and economic factors that shape the relationship between bears and humans. This will involve ongoing research to better understand black bear ecology, behavior, and population dynamics, as well as the development of innovative strategies for reducing human-bear conflicts and promoting coexistence. Education and outreach will also play a critical role in fostering a greater appreciation for black bears and their place in the natural world. By teaching people about bear biology, behavior, and the importance of protecting bear habitat, we can help to build a culture of coexistence that values the presence of these magnificent animals on the landscape. Additionally, the integration of Indigenous knowledge and perspectives into black bear conservation and management will be essential for developing culturally relevant and sustainable strategies for protecting bears and their habitats. By learning from the deep ecological knowledge and cultural practices of Indigenous peoples, we can gain valuable insights into how to live alongside black bears in a way that honors their intrinsic value and ecological importance. Ultimately, the future of black bears will depend on our willingness to coexist with them and to protect the wild places they call home. By working together to address the challenges facing black bears and their habitats, we can help to ensure that these enigmatic dwellers of the forest continue to thrive for generations to come. From the misty forests of the Pacific Northwest to the hardwood groves of the Appalachian Mountains, black bears have long captured the hearts and imaginations of those who share their world. Their remarkable adaptability, resilience, and enduring presence on the landscape serve as a testament to the power and beauty of the natural world. As we face the challenges of the 21st century, it is more important than ever to recognize the value of black bears and the ecosystems they inhabit. By investing -
Drie mensen zetten alles op alles om één diersoort, of zelfs een heel ecosysteem, te redden van de ondergang, want van de Nederlandse biodiversiteit is nog maar een fractie over. Maar de natuurbeschermers lopen tegen net zoveel obstakels op als de dieren waar ze voor vechten. Jennifer Pettersson volgt drie van hen twee jaar lang voor 'De weg van de dodo', een tragikomische serie over de haast onmogelijke opdracht om de natuur te redden van de mens. Jennifer, bekend van de prijswinnende podcast 'Opgejaagd', maakt deze zesdelige serie met bioloog Janneke Sindram, die elke aflevering een absurd maar waargebeurd sprookje vertelt over een uitgestorven diersoort.

Rechtsextremismus ist ein zentrales Problem für demokratische Gesellschaften. Um Rechtsextremismus verstehen, dem Phänomen gesamtgesellschaftlich begegnen und es bekämpfen zu können, bedarf es eines fundierten Wissens über die extreme Rechte, deren Strukturen, Themen, Strategien und Erscheinungsformen – insbesondere über die Verschränkung zwischen der extremen Rechten und der sogenannten „Mitte der Gesellschaft“.
Das Wissensnetzwerk Rechtsextremismusforschung – Wi-REX – bündelt Wissen aus unterschiedlichen Disziplinen, schafft Reflexions- und Interaktionsräume für Forschende, entwickelt passgenaue Formate für den Wissenstransfer zwischen Forschung, Praxis und Zivilgesellschaft und unterstützt gezielt junge Forschende, die zum Thema Rechtsextremismus arbeiten. Beteiligt sind das Institut für interdisziplinäre Konflikt- und Gewaltforschung (IKG) an der Universität Bielefeld, das Kompetenzzentrum für Rechtsextremismus- und Demokratieforschung (KReDo) der Universität Leipzig, das Institut für Demokratie und Zivilgesellschaft (IDZ) in Jena und das Institut SO.CON für Forschung und Entwicklung in der Sozialen Arbeit an der Hochschule Niederrhein.
Im Podcast „Über Rechtsextremismus reden“ wird Wissen über die extreme Rechte vermittelt und werden Ergebnisse der Arbeit des Wissensnetzwerks Rechtsextremismusforschung vorgestellt. Der Podcast ist auf allen gängigen Plattformen hörbar. Um keine Folge zu verpassen, abonnieren Sie den Kanal.
