She asks the plants for permission before foraging them. She sings to her fermentation jars. She prepares funerals for her kombucha scobies. She gives names to her ferments. She observes the moon cycles. She’s a witch. But what does it mean to be a witch today? I asked this to Paulina Gretkierewicz, a forager, a fermenter, and a witch. She transforms seasons and landscapes around Copenhagen, Denmark into edible and drinkable experiences. She calls this “Applied Poetry”, which is also the name of her business, focused largely on handpicked, fermented, and oxidized teas. Let’s ferment our way into becoming a witch.

Have you ever heard of slime mold? These organisms might not have a nervous system or even a brain, but they have impressive problem-solving abilities. Slime mold can navigate through mazes and find the most efficient routes to find food. Some researchers have already been inspired by them to design more efficient transportation networks, urban planning, and solving optimizational problems. However, they are shrouded in a haze of mystery. They are hard to like, observe, and classify. In this episode, together with Heather Barnett, an artist and university professor at Central Saint Martins University of the Arts London, working with natural phenomena, complex systems, and playful pedagogies, we look at slime mold beyond their instrumental features and focus on their intrinsical importance as a remarkable lifeform. Instead of thinking: What can we extract from these species? We want to ask ourselves: What can we actually learn from them? Join us in this fascinating and meandering, or shall we say, “slimemoldesque” conversation.

A healthy food system encourages the production and consumption of foods that support a balanced gut microbiome. It reduces food waste and gives preference to natural preservation methods. It uplifts food, not only for its nutritional value but also as cultural heritage and an expression of diversity. It is also mindful of the energy spent in order to process food. All these characteristics of a healthy food system sound very much like the definition of fermented foods. It may seem like a simple solution, but diagnosing and improving the complexity of the food system, which is both global and fragmented,  is a huge challenge. There are not that many people in the world who can say they have extensive hands-on experience working in different areas of that vast system. David Zilber is definitely one of them. From a butcher shop in Toronto to the Fermentation Lab of the acclaimed restaurant Noma, Copenhagen, and to the labs of Chr. Hansen, a giant bioscience company in Hørsholm, Denmark, David Zilber has garnered multiple and fascinating perspectives on food and the system around it. Ferment Radio had the pleasure to talk with David in his own lab, where we reflected more about this incredible journey and his ever-evolving views on the food system that we are all part of.

Garden. It invites us to sit down and watch things grow. It makes us work with gazillions of other species to make them flourish. Silent observation or site-specific, mindful labor can be a form of wondering: seeing magic in what’s common and perceiving what’s repetitive with new eyes. This is how Noora Sandgren, a visual artist and art educator from Finland, works in her family garden. She collaborates with climates, insects, and expired light-sensitive material to create cameraless photograms of shared chemistry of composting organic matter, microbes, human breaths, and sunlight. In this episode, Noora takes us to her garden where she wonders while taking lensless images and patiently waits for long exposures for the magic to happen.

We associate these institutions with petrified displays, and long-gone worlds that are alien to our own experience: museums. Whether we like it or not, they play a crucial role in preserving heritage. Can heritage be something alive and ever changing? It seems that yes. At least ARTIS-Micropia, a one-of-a-kind museum showing the invisible world of micro-organisms, is doing that. ARTIS-Micropia is a museum in Amsterdam in which visitors can learn more information about microbes, and see live microbes on display too. The museum fills a gap between the general public’s knowledge on microroganisms, and the science behind microbiology. “Unknown is unloved” they say on their webpage, and they definitely want to change that. On Ferment Radio’s new episode, we talk with ARTIS-Micropia’s lab technicians Loek van Buuren and Eline van Bloois about curating microbes, preserving what is alive, and dreaming about immersive microscopial experiences, which could allow us to float with microbes in their micro universe.

Can we intentionally influence our nervous system through what we do? If so, could we also activate the main nerve of our parasympathetic nervous system known as vagus nerve?  This is the central communication pathway between the gut and the brain, and between microbiota and our nervous system. Could we interact with our gut microbiota and our gut microbiota interact with us? In this episode of Ferment Radio, together with Riina Hannula, we start with Microbial Medi(t)ation, an instructional audio that guides us through selected movements from yin- and hatha yoga to stimulate the vagus nerve. With this meditation, we wonder if it is possible to embody scientific facts and if our well-being involves the well-being of our microscopic companions as well. Riina Hannula, an artist and doctoral student in sociology at The Centre for the Social Study of Microbes at the University of Helsinki,  studies humans as holobionts from a gut-brain-axis point of view and looks into how microbes think, feel, and behave with humans.

We communicate with the outside world based on the information we receive through our senses. But just like fingerprints, no two people have the same brain anatomy, and therefore, no two people can sense the world identically. We can’t experience how other bodies feel, but we can attempt to describe it. Today, together with Pia Lindman, an artist and researcher working with performance art, healing-as-art, installation, microbes, architecture, painting, and sculpture, we dive into the uniqueness of bodily experiences; even those caused by microorganisms. Pia calls this, the subsensorial.

The notion of “animal rights”, meaning that we recognize their universal, intrinsic rights, regardless if some animals are more useful for humans or not, is being talked about more and more these days. However, we can’t fully understand the lives of animals, and as result, we can’t understand our own lives without microbes and our relationship with them. Our lives depend on them. In other words, we belong to them. This episode revolves around speculative microbial perspectives in the work of Terike Haapoja. Terike is a visual artist based in New York, whose work investigates animality, multispecies politics, cohabitation, repairing connections, and the existential and political boundaries of our world. Her research and work put a special focus on issues that emerge from the anthropocentric worldview of Western traditions.

Through language, we not only reflect our relationship with the world but also shape it. For example, what does the conviction that we need to “exterminate all superbugs” tell us about humans? Could it be that antimicrobial resistance, which causes antibiotics to become ineffective against microbial infections, is in part driven by a human desire to separate human from nature and eradicate what is ‘impure’, different, or misunderstood? On the 30th episode of Ferment Radio, together with Iona Walker, a medical anthropologist living and working in Edinburgh, Scotland, we search for different perspectives on this alarming issue and find inspiration in books, art, films, and poetry. We look for cracks, soft spots, and ambiguities to unlearn what we think we know for sure and exercise a new language that could help reshape our relationship with the world, including microbes. Join us in this exciting conversation!

On Ferment Radio, we have often talked about how artists use technology and science in order to tackle the microbial world. Do you remember the episode “Play that fungi music!” with Tosca Terán? Or “Interspecies collaborations” with Mindaugas Gapševičius? Some people refer to this kind of practice as “bioart”: the happy place where experimentation and process are more important than concrete results. Our guest today is Laura Beloff, an artist, and researcher working at the intersection of art, science, and technology. Laura is also an associate Professor, and Head of the Visual Cultures, Curating, and Contemporary Art Program (VICCA) at Aalto University, in Helsinki, Finland. On this episode of Ferment Radio,  we will delve into the dynamic interdisciplinary niche that likes to collaborate with microbes; reflect on the ethics of working with living organisms; and discuss the incompatibility of a creative endeavor within a neoliberal reality. Oh, and we will also talk about ticks! As Laura Beloff points out: artists are antennas for societal moods, and there is a reason why they engage with microbes. And what’s the reason? Stick around and tune into the 29th episode of Ferment Radio to find out!
