The Invisible Climate Engineers Running Our Ocean

Ocean microbes quietly power the planet. In this episode, we explore the microscopic organisms that regulate Earth's climate, produce much of the oxygen we breathe, and move enormous amounts of carbon through the ocean every day. These invisible life forms are not just background players in the ocean system; they are central to how the planet works. Synthetic biology is now pushing this idea even further. Dr. José Ángel Moreno-Cabezuelo, a synthetic biologist working in Oxford, is engineering ancient microorganisms called cyanobacteria to capture carbon dioxide using sunlight and biology. His work shows how living systems could become part of the climate solutions we desperately need. Science communication is another major theme of this conversation. After years working inside the scientific system, Dr. Moreno-Cabezuelo began questioning why so much scientific knowledge fails to connect with society. Through his book Heartbeats of Consciousness, he explores the intersection of biology, neuroscience, philosophy, and the human experience, asking a powerful question: if science understands life so well, why does it still struggle to help us understand how to live it? Listen to learn how microbes shape our planet, how biotechnology may help tackle climate change, and why clarity in science might be one of the most important tools we have for protecting the ocean.
