    Inside Alexandrea Pangburn’s World of Wildlife Art

    A mural can be more than just a pretty backdrop for the city streets. But when the mural is four or five stories tall and features the face of one of the area's native animals, it’s likely to make people stop and consider the species and their place in the town's environment. 🎨  Alexandrea Pangburn is a mural and animal art artist who has dedicated her career to creating massive murals of animals that people end up feeling protective of. 👩‍🎨  With over 20 years of experience in the industry, Alexandrea shares with us her journey from Kentucky to Colorado, the influence of the Western landscape on her art career, and her unique style that includes realistic depictions of animals with retro 1970s color palettes and an understanding of the way sunlight plays on the animals’ coats. 🖼️  Alexandrea also shares the challenges of working outdoors in the heat and with the weather, her tools of choice, the differences between gallery art and mural art, and the various mural commission requests that she has received throughout the years. 🌱  Alexandrea shares how she captures the essence of her pet portraits by focusing on their eyes to depict their personalities and to release the emotions that come from the passing of these beloved companions. 🐶  ______________________________________ Nature is closer than we think 🌿 “I want people to be able to see the beauty and the details of the animals and plants that live among them.” Alexandrea Pangburn, muralist and animal realism artist, shares how her work brings attention to the natural world around us.

    What Deep Isolation Is Doing Differently with Nuclear Waste

    While managing spent fuel from current commercial reactors is a major concern for nuclear engineers today, one question remains about nuclear energy, SMRs, and next-gen reactors: where does spent fuel go long term? Rod Baltzer from Deep Isolation explores how spent fuel can be placed about a mile below the surface into deep boreholes using directional drilling techniques. ☢️ Spent fuel from commercial reactors is dangerous because of the radioactive decay of the nuclear material. While storing spent fuel is important, it is not the same as permanently disposing of it. Deep geological deposits and long-term safety of the spent fuel will keep the potential impact on the surface to a minimum. However, a significant portion of the population already lives near stored spent fuel nuclear waste. Yet, if spent fuel can be stored beneath ground where spent nuclear waste already exists, people’s perspective on the issue will change. ⚡ Discussing the technical details of this process, the discussion also covers the specifics of the canister that will contain the spent fuel. Furthermore, nuclear quality assurance will be essential for the transportation and storage of spent fuel. Finally, Baltzer discusses what an early commercial facility will look like and why the speed of SMRs and next-gen reactors could be the key to solving the issue of spent nuclear fuel waste. 🌎 _____________________________________  “Nuclear waste is handled and transported and stored very safely… but it is very radioactive.”  Rod Baltzer, CEO of Deep Isolation, explains why long-term storage still matters, and how his team is approaching it differently.  Support the show

    How Janelle Lynch Sees Beyond the Image

    A great photograph does not always start with an idea. Sometimes the physical 'yes' forms within the body when the light hits the subject just right. ☀️ We talk with photographer Janelle Lynch about her creative process in landscape photography, her more recent portraits, and her cyanotypes, made with a nineteenth-century cameraless technique. Janelle shares how she developed her love for the camera from her early experiences of being seen by others, why she avoids the word 'capture,' and how her images often emerge through a conversation with her subjects. We also get into her craft and the work that she does with her 8x10 view camera. 📸 Janelle draws inspiration from various sources and incorporates practices into her routine, such as yoga, proprioception, and perceptual drawing and painting with others. One of the visuals Janelle shares with us is an eight-minute exposure taken in near darkness, which leads to a discussion of what exists even when we cannot see it. 🍃 ____________________________________ “To have a meaningful connection with nature, you don’t have to go far.” Photographer Janelle Lynch shares a perspective that finds nature where most people don’t think to look. 🍃📸 Support the show

    Safe by Design: How Terra Innovatum’s Micro Reactors Are Changing Nuclear Energy

    The grid is strained, AI data centers are exploding in demand, and clean baseload is once again on the table. Alessandro Petruzzi, Co-Founder and CEO of Terra Innovatum, joins the show to talk about a different kind of nuclear power: micro modular reactors that are safe by physics, not by emergency equipment. ☢️ Terra Innovatum has developed the Solo, a 1 megawatt electric micronuclear reactor. Alessandro discusses how 1 megawatt is physically small-scale, how the low power makes decay heat much easier to manage, and how the reactor is engineered so it cannot melt down. He also shares how the company is using existing nuclear fuel and supply chains to build the reactor, which will shorten the timeline to building the first one. 🏭 For use cases, Alessandro shares how these nuclear reactors could supply power to AI data centers waiting on grid transmission upgrades, mining operations that need to reduce their CO2 emissions, and even provide bonus outputs that may be even more important. Microreactors can provide desalinated water to areas with water scarcity issues or produce medical radioisotopes for hospitals to treat cancer patients. ⚡ ___________________________________________ “Energy means progress. Without energy, you don’t progress.” Alessandro Petruzzi, Co-Founder and CEO of Terra Innovatum, explains how micro nuclear reactors could bring reliable power to industries, data centers, and remote communities worldwide. ⚡🌍 Support the show

    Almost Human: How Realbotix Is Redefining Humanoid Robots

    A humanoid robot that looks you in the eye, answers questions in 100+ languages, and continues to chat with you long after the camera crew has left… sounds like science fiction. Yet, this is the future that is quickly becoming the present for companies like Realbotix. In this episode, CEO and Executive Chairman Andrew Kiguel talks to us about the company behind the humanoid robots and why the talking robots of the future may be the first to populate our public spaces. 🤖 Andrew discusses the company’s start with silicone robots meant for film. He discusses how the company began adding motors and movement to its lifelike figures without sacrificing human proportions. The importance of using robots to express facial emotions, use a friendly voice, and foster companionship when interacting with patients in hospitals and schools is discussed. 🏥 The interview turns to the technology behind these humanoid robots. How they use embedded artificial intelligence to “see” the world around them in ways that allow them to understand their environment. Their use of plug-in power to give them longer operating times without batteries, their use of suitcase-sized robots that can travel from place to place easily, their use of various AI programs that can be downloaded and installed like an app store, and their discussions of automation and the new jobs that will be created in the future. 🦾 ___________________________________________ “We started with the human form and asked how do we add mechanics and motors to maintain the human figure.” Andrew Kiguel, CEO of Realbotix, explains how the company builds humanoid robots designed to interact naturally with people. 🤖🧠 Support the show

    Constant Bloom: Following the World’s Longest Butterfly Migration with Lucas Foglia

    This episode features the guest Lucas Foglia, a photographer with a deep connection to nature. From the micro to the macro, from intimate to planetary systems, Lucas captures the nuances behind his subjects and helps usher in real-world change. From his Long Island farm childhood, Lucas creates a body of work that pulls nature back from any notion of a museum diorama or a lost paradise. His newest book, Constant Bloom, sheds light on the longest known butterfly migration from Kenya to Norway and back. A photo he took in Barcelona shows blooms above a melting glacier, taken by a researcher who happened to be on his own scientific journey across borders. In this episode, you will hear about his other compelling books, such as A Natural Order, which explores off-grid lives after the recession, and Front Country, which balances Western wildness and extraction. You'll also hear about Human Nature's blend of neuroscience and conservation. Lucas speaks about his photographic processes, practices, and philosophy, offering an excellent taste of how art goes from "huh" to "wow" and how a quiet picture from the Rikers Island garden program helped expand it. He talks about collaborating with people, calling it "photographing with, not of," and giving practical guidance like making friends, not networks, starting with one honest question, and offering counterpoints to today's loudest headlines. If you're feeling squeezed by algorithms or doom, this is a reminder that depth still matters, and that images can open doors to empathy and action. If the stories resonate, please subscribe, share the episode with a friend, and leave a review telling us the last image that changed how you see the world. Purchase a copy of Constant Bloom here!

    How Selin Balci Turns Microorganisms Into Living Works of Art

    In this episode, we are joined by artist Selin Balci, whose art begins not with paint but with living microorganisms. A former forestry and microbiology student, Selin explains how she collects microbes from soil, trees, water, and even the human body, then isolates and cultivates them into controlled art pieces. We talk about the science and art of sterilizing tools, nutrient mediums, contamination, and how she decides when to stop and when a piece is finished. We touch on her project, Echoes of Nature, in which mold consumes Polaroids of actual nature scenes to signify the end of nature as we know it, and 30 Faces, where people’s microbes reform the portraits of their faces over time, making them interactive. Selin also ponders imperfection, rot, why contamination is not always a mistake, and the questions her art evokes about identity and sustainability. If you’re interested in where art, science, and the natural world intersect, this is a rare glimpse into microscopic art. Support the show
