About this episode
Energy is vital for life. It allows important functions to occur in living systems, from the molecular level to the scale of the whole organism. Dr Helen Greenwood Hansma, from the University of California in Santa Barbara, believes that the types of energy used in living cells can provide clues to help us understand the origins of life. In her recent research, she explores how mechanical energy could have driven the processes that gave rise to early life in the absence of chemical energy.

Dr Malgorzata Trela – Dr Sophie Rutschmann | From Classroom to Conference: How a New Teaching Model Lets Students Step Inside the Scientific Community
When you imagine a scientific conference, you may picture rows of poster boards, bustling coffee breaks, and seasoned researchers discussing the latest data and research approaches. It can feel like a world reserved for insiders. Yet a recent study led by Dr Malgorzata Trela and Dr Sophie Rutschmann at Imperial College London argues that this lively professional gathering is precisely where tomorrow’s scientists ought to cut their teeth. Their paper, “Immunology in Practice: a modular framework to support Master of Science students’ conference attendance and engagement,” describes an educational project that turns a four-day professional congress into the beating heart of a master’s-level module, and in doing so, reshapes how students learn, network and even see themselves.
Ren Kimura | Listening to Our Cats’ Kidneys: How a Handful of Mirror-Image Molecules Could Reveal Feline Health
Amino acids are a fundamental building block for fur, muscle, and every other living tissue on Earth. These molecules come in “left-handed” (L) and “right-handed” (D) forms, a bit like gloves that fit different hands or mirror images. Life largely runs on the left-handed set, so biologists once assumed the right-handed versions were irrelevant. Yet nature quietly manufactures these D-amino acids and they can play a role in certain biological processes. In research led by Japanese analytical chemist Ren Kimura of the R&D-Analytical Science Research department of the Kao Corporation, Japan, researchers reveal that these overlooked molecules may offer an early-warning beacon for one of the most common and deadly ailments in cats, chronic kidney disease (or CKD for short), and they may even have potential in diagnosing human conditions.
Dr. Arthur Snow | From Firefighting Foams to Molecular Mysteries: A Surfactant’s Unexpected Journey
Scientific discovery often unfolds in unexpected ways. What begins as a search for solutions to real-world challenges can lead researchers into unexplored scientific territory, where unconventional ideas emerge and spark debate. This dynamic was at the heart of research by Dr. Arthur W. Snow and Dr. Ramagopal Ananth in the Chemistry Division of the US Naval Research Laboratory. Their study aimed to address a pressing need: replacing fluorocarbon surfactants in firefighting foams. What they discovered would take them beyond firefighting applications and into fundamental questions about the nature of water itself.
Dr. Jon Reinders | A genetic breakthrough for farming: editing corn inside the plant, not the lab
Corn is a cornerstone of modern agricultural food production, particularly in North America. Humans have selectively bred such crops over generations to create better yields, improved appearance and flavor and enhanced disease resistance. However, what if we could skip these arduous rounds of selective breeding and improve a crop’s stability and reliability regardless? Deep within the genetic blueprint of every maize kernel, scientists are aiming to achieve just this. In a recent groundbreaking study, Dr. Jon Reinders of Corteva Agriscience and his colleagues have unveiled a powerful new way to create genetically improved corn, not in a lab dish, but inside the plant itself. This new method is faster, cleaner, safer, and could transform how we grow our most essential crops.
