Send us Fan Mail Originally Published Under: Life Is A Story We Tell Ourselves “When I first saw the fossil of a blood-engorged mosquito, it was one of the most interesting, amazing moments in my life—because I realized this was something that no one on the planet had ever seen before. I was the first human being to ever look upon a fossil of a blood-engorged mosquito.” — Dr. Dale Greenwalt We long believed fossils were composed strictly of rock and minerals, all original molecular traces of life erased by millions of years of heat and pressure. We were wrong.In this episode, paleobiologist Dr. Dale Greenwalt guides us through the revolutionary science of ancient biomolecules—pigments, proteins, and DNA preserved in the fossil record across tens of millions of years. From decoding how mammoths survived extreme Arctic cold to uncovering the true colors of dinosaur feathers, analyzing surviving biomolecules allows us to reconstruct the physiology, behavior, and evolutionary trajectories of extinct organisms like never before.Key Takeaways from the Discussion Beyond Stone and Bone: Fossils are not merely mineralized casts; fragile organic molecules can persist under unique geological conditions for tens of millions of years. Paleogenomics & Proteomics: Analyzing fossilized proteins and pigments offers deep insights into physiological adaptations—such as cold-tolerance in prehistoric mammals and pigment-based mating displays in dinosaurs. The Jurassic Park Parallels: Dr. Greenwalt shares his discovery of the first-ever blood-engorged mosquito fossil, demonstrating how ancient blood and molecular remnants can survive across geological deep time. Evolutionary Deep Time: Tracing ancient viral genomes and molecular structures helps us understand how modern pathogens evolved and adapted over millions of years. #Paleontology #SciencePodcast #Fossils #STEM #ScienceCommunication #Geology #DeepTime #EvolutionaryBiology Full Transcript Available At: https:/natureandsciencepodcast.com

Send us Fan Mail We like to believe that we navigate our lives as fully conscious, rational architects of our own destinies. But how much of the life you are living right now is a result of deliberate, conscious choice—and how much is dictated by unseen cognitive shortcuts, subtle societal defaults, and hidden behavioral biases? In this episode of Journey Through Nature and Science , host Donald Murphy sits down with renowned behavioral economist and best-selling author Dan Ariely for a profound conversation at the intersection of psychology, choice, and human awareness. Together, they explore the boundary between automatic habit and intentional living. From the subtle forces that steer our decision-making to the deep alignment required to live a truly conscious life, this discussion challenges us to pause, look beneath the surface of our daily routines, and ask: Are we truly conscious of the life we should live? Key Topics Covered The Illusion of Rational Control: Why human beings consistently act against their own best intentions—and why intellect alone doesn't guarantee conscious choices. The Architecture of Choice: How small, unexamined environmental cues shape our major life decisions without our awareness. Bridging Behavioral Science & Consciousness: Merging the empirical study of human irrationality with the deeper search for personal meaning and alignment. Awakening to Intentionality: Practical insights for stepping out of automatic default patterns and reclaiming agency over your path.

Send us Fan Mail "An archival 2023 interview with Anthropic co-founder Jared Kaplan discussing scaling laws, large language models, and the trajectory of artificial intelligence." "What is the universe? What is intelligence? What is the mind?" When theoretical physicist turned AI researcher Jared Kaplan shifted his focus to artificial intelligence, he wasn't just looking to build software—he was trying to answer fundamental questions about reality, perception, and thought itself. In this episode, we’re revisiting a 2023 conversation with Jared, co-founder of Anthropic, recorded just as he was joining the company. At the time, we sat down to discuss the physics of intelligence, scaling laws, large language models (LLMs), and where machine intelligence was heading. Looking back three years later, with tools like Claude and ChatGPT transforming the global landscape, listening to this snapshot offers an incredible look at how fast the field has evolved—and how much of today's reality was already taking shape in those early research models. We begin with Jared sharing the story of what first drew him from physics into the world of AI, driven by the ultimate quest to understand how mind and universe intersect. In This Episode, We Cover: From Theoretical Physics to AI: How foundational questions about the universe and human cognition led Jared from fundamental physics to machine intelligence. The Physics of Scaling Laws: Understanding the empirical patterns that predict how language models improve as computing power, data, and parameters expand. Large Language Models & Emergent Abilities: Early insights into how LLMs acquire complex reasoning behaviors. The Trajectory of AI Safety & Alignment: Why Anthropic was formed and the core challenges of building safe, cooperative frontier models. https:/natureandsciencepodcast.com Full Transcript Available At: https:/natureandsciencepodcast.com

Send us Fan Mail Is The Earth Losing Its Balance and beginning to turn against us? Author Dominic Nessi explores that terrifying possibility in The Source , a gripping new science thriller that combines geophysics, political suspense and human survival in a story where Earth’s very stability begins to unravel. The first installment in a planned trilogy, The Source follows a team of brilliant women scientists racing to understand a growing series of magnetic disturbances, seismic irregularities and atmospheric anomalies that suggest the planet’s rotational balance may be shifting — with potentially catastrophic consequences for civilization. At the center of the story is Christina Whiting, a NASA geospace specialist whose discoveries challenge humanity’s understanding of the world beneath its feet. As governments react with denial, fear and escalating desperation, the race for answers becomes a global struggle defined as much by politics and survival as by science itself. The Source “The Source is ultimately about people,” Nessi says. “It’s about how ordinary individuals respond when systems fail, certainty disappears, and science collides with fear. I wanted the story to feel intellectually grounded, emotionally personal and frighteningly plausible.” Drawing inspiration from real scientific theories, archaeological mysteries and modern geopolitical tensions, The Source has been described by early readers as “Michael Crichton meets Hidden Figures ,” combining large-scale disaster storytelling with a distinctly modern, female-centered perspective. The book is expected to resonate strongly with readers of speculative thrillers, science-driven fiction, and book club audiences looking for stories that blend suspense with deeper philosophical questions about humanity’s future. www.sourcematrix.info Full Transcript Available At: https:/natureandsciencepodcast.com

Send us Fan Mail Welcome to my third memoir about my unusual trajectory in the world of medicine. In my first memoir, “ Medicine and Miracles in the High Desert ,” I shared with readers my profoundly life-changing and eye-opening time on the Navajo Reservation as a young schoolteacher in the early 1970s. Many years later, I returned to the Navajo people to serve them as a medical doctor in Cuba, New Mexico. The second memoir, “ From Mountains to Medicine ,” takes the reader on a spellbinding, ten-year odyssey in search of my life’s purpose. This memoir begins with my wide-eyed excitement upon entering medical school. I had an unquenchable eagerness to learn information and skills that would help others. I held no pre-conceived ideas about the kind of education I would receive. Gradually, as time passed, I began suspecting that something wasn’t right about some of the information that the professors and mentors taught the medical students. Long after I completed my training, I discovered why some of the information I learned didn’t make sense, and the conflicts of interest involved in many of the studies that were done that influenced what the medical students were taught.

Send us Fan Mail Hello everyone, I'm your host of Nature and Science Podcast, Don Murphy. In the episode I am interviewed by our producer, Anna Murphy to discuss, how my two time failure in chemistry ultimately led to the founding of Ky'Orda. The mission of Ky'Orda is to eliminate the fear and failure in learning complex subjects for everyone by creating an education app with a personal guide that uses behavioral science and adaptive technology. I think many of you out there can identify with failing a subject and feeling like you didn't measure up or at the worse you were not smart. You may have even abandoned a subject before you even got a chance to explore its adventures and discoveries. The guided app I will talk about is creating an entirely new world and may ultimately change the way education in done worldwide. So join us this next episode and be amazed.

Send us Fan Mail Scientific research at Yellowstone and other National Park has yielded many useful discoveries benefiting humanity. One of the most important was the discovery of the thermophilic bacterium, Thermus aquaticus. Later an enzyme was purified by a team led by Dr. Henry Erlich, which led to the practical use of the PCR test in covid detection and many other uses. Science in parks is a crucial tool for the advancement of humanity. However, if it were not for the early efforts of George Menendez Wright, science may have never taken hold in our national parks. Today, the George Wright Society continues that effort by supporting parks, protected/conserved areas, cultural sites, and other kinds of place-based conservation by encouraging communication among and convenings of researchers, managers, educators, practitioners, and the public to facilitate informed decisions and actions that embrace our values. Joining me to talk science in our national parks is Dave Harmon, executive director of the George Wright Society. Dave is responsible for overseeing the George Wright Society’s operations, including co-editing Parks Stewardship Forum and helping plan workshops and other meetings. A member of the GWS since 1985, Dave began working for the organization in 1990 and served as executive director from 1998 to 2017 before returning that role in 2019. He is active in IUCN's World Commission on Protected Areas. He also maintains a research interest in the relationship between biological and cultural diversity, having co-founded the NGO Terralingua, which is devoted to that subject. Dave has co-edited several volumes on protected area conservation, including The Antiquities Act: A Century of American Archaeology, Historic Preservation, and Nature Conservation (with Francis P. McManamon and Dwight T. Pitcaithley), The Full Value of Parks: From Economics to the Intangible (with Allen D.
