New Paper on Bacterial Cellulose Out Now
Bacterial cellulose (BC), a promising versatile biopolymer produced by bacteria, has immense potential in various industries. However, large-scale application is hindered by high production costs and low yields. This study introduces an innovative approach combining a prolonged static culturing with intermittent harvesting. The findings by the interdisciplinary team, which also included Cluster members Bastian Beyer, Cécile Bidan, Regine Hengge, and Skander Hathroubi, highlight the potential of intermittent harvesting for sustainable BC production and the role of bacterial adaptation in tuning BC properties.

Installation »Bacterial Cellulose: Co-Weaving Biofilms« Featured at Exhibition in Dessau
Was the historic Bauhaus interested in ecology? Presumably in a different context than today. The exhibition »Bauhaus Ecologies«, on view from April 11th to November 2nd, 2025 at Bauhaus Museum Dessau, explores approaches to ecological thinking in modern design. We are thrilled to share that the exhibition also features the installation »Bacterial Cellulose: Co-Weaving Biofilms« developed in the Cluster of Excellence »Matters of Activity«. The project of architects Bastian Beyer and Iva Rešetar and microbiologist Regine Hengge presents the latest results of research at the interface between design, materials science, and biology.

Cluster Member Emma Sicher Gives Talk at Futurium
Moderator Pireeni Sundaralingam, a cognitive scientist, and her guests, Emma Sicher, MoA Pre-Doctoral Researcher and Anna Yona, founder and managing director of »Wildling« will discuss the future of sustainable design and the unconventional use of raw materials at Berlin’s ›House of Futures‹. Emma is a designer investigating materials and foods at the intersection of microbiology and anthropology to envision relational futures. What would happen if we used different materials for our clothes and our shoes? How could our food systems or our buildings use completely different raw materials? A ticket is required, but the admission is free of charge.

Presentations Doctoral Program 2024
Under the title »testing un/common grounds«, the Matters of Activity doctoral cohort impressively presented the progress of their diverse research projects during the Cluster retreat. The event included the three moderated panel discussions as well as an exhibition of selected research objects that were at the core of the format. With their various disciplinary backgrounds ranging from art, architecture, engineering and design to the humanities and natural sciences, the group explored this interdisciplinary ›un/common ground‹ and aimed to develop forms of common knowledge that respect locally-based actors and embrace collaborations with diverse agencies and species.

Emma Sicher Exchanged Knowledge with Researchers and Practitioners in Thailand
Between May and June, doctoral researcher Emma Sicher spent three weeks in Thailand as part of her PhD in Design Studies. Invited by Professor Aracha Krasae-in, she presented the work of the Cluster and her current research at the Faculty of Architecture of Kasetsart University in Bangkok. There, she also exchanged ideas with Professor Prakit Sukyai, an expert in Biotechnology and Biopolymers. Additionally, she presented at the Faculty of Fine and Applied Arts of Thammasat University, invited by Professor Wuthigrai Siriphon.
The heart of the experience consisted of visits to two sites associated with acetic fermentation techniques that can generate biomaterials. These techniques range from ancient practices to more recent methods, employed in various ways from fertilizers to health-promoting substances. The visits took place in small artisanal production realities in Nakhon Ratchasima province, including Stefano and Somporn Abbruzzese, and Micro Friends, an initiative run by Tanyaporn Tantasathien and Waratchanat Thongthiangtham at the Baan Ama farm stay. more

Open Lab Abend der Reihe »Materialzukünfte besuchen« im Futurium
In diesem Workshop ging es um flexible Materialien wie Cellulose, Bio-Plastik und Silikon als mögliche (neue) Materialien für Soft Robotics oder gar biologische Maschinen. Soft Robotics ist ein relativ junges Forschungsfeld, das sich mit alternativen Ansätzen zur Gestaltung der Maschinen von morgen beschäftigt. Wie können wir Maschinen bauen, damit sie sensibler und anpassbarer werden? Können wir dafür adaptive vielleicht sogar nachhaltige Materialien nutzen, statt immer mehr Metall, Plastik und Energie zu verbrauchen? Mit den Design-Forscherinnen Anna Schäffner und Eva Bullermann spekulieren wir darüber, wie die Maschinen der Zukunft gestaltet sein könnten. Wie sieht deine Magic Machine aus?

Pioneering Publication on Biomaterials Launched in Buenos Aires
»Trazos« is a pioneering publication in Spanish in the interdisciplinary field of biomaterials developments. The book is divided into three sections which explore, interrogate, shape, and reflect on these scientific and creative advancements. This book encourages interaction between the Spanish-speaking community and provides access to a topic predominantly discussed in English. It seeks to stimulate dialogue and amplify the reach of the Latin American biomaterials field to a broader audience. Likewise, it aspires to foster collaborations that transcend language barriers, promoting enriching exchanges of ideas and knowledge. The book, edited by MoA Associated Member Heidi Jalkh and Gisela Pozzetti, and designed by Paula Rodríguez, includes contributions by MoA researchers Bastian Beyer, Johanna Hehemeyer-Cürten, Wolfgang Schäffner, Daniel Suárez, Charlett Wenig and by Rodrigo Martin Iglesias, Coordinator of the Master Open Design.

Workshop Series at Futurium
Gestaltet das Futurium Lab selbst mit! In der öffentlichen Workshopreihe »OPEN LAB ABEND: Materialzukünfte besuchen« spekulierten Teilnehmende darüber, aus welchen Materialien die Welt von morgen gemacht sein könnte. Die Workshopreihe umfasste 4 Termine und fand von März bis Juni im Futurium statt. Forschende von »Matters of Activity« (MoA) gaben Einblick in ihre Arbeit. Davon ausgehend entwickelten Teinehmende Zukunftsszenarien und gestalteten Prototypen, die im Anschluss zusammen mit Objekten aus der MoA-Forschung im Lab ausgestellt wurden. Begleitet wurden Teilnehmende dabei vom spekulationserfahrenen Team von »CollActive Materials«.
It’s getting hot in here... In diesem ersten Workshop ging es darum, wie wir mit smarten Materialien die Städte der Zukunft gestalten können. Im Sommer machen steigende Temperaturen, Metall und Beton das Leben in der Innenstadt für alle Bewohnenden immer mehr zur Herausforderung. Welche Materialien schaffen Abhilfe in überhitzten Städten?

An Installation for the Triennale XXIII: »Unknown Unknows, An Introduction to Mysteries«
Cellulose of different forms and origins is woven together in this structure: pieces of wood, paper threads and biofilms grown by bacteria. A collaborative textile is created – human, plant and microbial. Three MoA research projects, Weaving, Material Form Function and Object Space Agency and with that many MoA Members worked together on the project »Bacterial Cellulose: Co-Weaving Biofilms« shown at the Triennale di Milano XXIII »Unknown Unknows, An Introduction to Mysteries«, in the thematic exhibition »Alchemic Laboratory«, curated by Ingrid Paoletti, from July 15th to December 11th, 2022.

Essay by Regine Hengge and Karin Krauthausen on the Occasion of the Exhibition »Hella Jongerius: Woven Cosmos« Published
Regine Hengge's and Karin Krauthausen's essay »The Event of Fibre« has been published in the volume accompanying the exhibition »Hella Jongerius: Woven Cosmos« which was shown in Berlin's Gropius Bau from April 29th to September 15th, 2021.
Whether in DNA interactions, bacterial biofilms or city architectures, weaving can be a model for different and relational »ecologies of life«. Ranging across artistic practices, cell biology, and human forms, molecular biologist Hengge and cultural historian Krauthausen (both Project »Weaving«) examine what we can learn from nature's enmeshed processes.
