The work, led by Professor Christof Niemeyer of KIT’s Institute for Biological Interfaces 1, refines a concept known as all-enzyme hydrogels, or AEH. The central idea is elegantly simple. Individual enzymes are equipped with complementary molecular binding modules, engineered so that when the modified proteins meet, they recognize one another and spontaneously organize into three-dimensional protein networks. The result is a material in which the catalysts are not immobilized on or inside a foreign support, but instead constitute the structural material of the catalyst itself.

“When the complementary building blocks come together, they organize themselves into three-dimensional protein networks,” Niemeyer explained. “Thus, the enzymes are catalysts and the structural material of the beads at the same time – a great advantage over conventional methods. We avoid inactive support material, increasing the efficiency of the desired chemical reaction.” This carrier-free design matters because traditional enzyme immobilization typically requires polymers, resins, or other matrices that add mass and volume but contribute nothing to the reaction. Every gram of inactive support dilutes the catalytic power of a reactor. By eliminating that dead weight, the AEH approach concentrates catalytic activity where it is needed most.

The fabrication process developed by the KIT team proceeds in two steps and relies on techniques familiar from materials science rather than from synthetic chemistry. First, the complementary enzyme building blocks are combined within liquid droplets, where self-assembly into protein networks begins. The droplets are then rapidly frozen in liquid nitrogen, which consolidates the emerging structures. A subsequent freeze-drying step removes the water by sublimation, leaving behind mechanically robust, porous protein beads with a defined size. The dried particles can be rehydrated on demand and immediately deployed in biocatalytic reactions, which makes them storable, transportable, and easy to dose – precisely the properties that industrial process engineers require before a laboratory concept can be considered for production environments.

Versatility is the second pillar of the new technology. The researchers demonstrated that very different enzymes and reaction types can be incorporated into the beads, spanning both single catalytic functions and multi-enzyme cascades, with or without additional additives. “The composition of the material can be customized to suit the desired reaction,” said Niemeyer. “This is some sort of modular system: We can assemble different enzyme modules to catalytic networks using defined binding molecules and subsequently transform them into a particle form that is easy to work with.” In practice, this means a process developer can select the enzymes appropriate for a target molecule, attach the matching binding modules, and assemble a bespoke catalytic particle tailored to that specific transformation – a degree of programmability that fixed commercial supports cannot easily match.

The team also showed that the AEH beads perform in continuous-flow reactors for many hours. Continuous flow is the operating mode of choice in modern fine-chemical manufacturing because it offers consistent product quality, precise control of residence time, straightforward scale-up by numbering-up, and simplified separation of product from catalyst. Demonstrating that self-assembled, carrier-free protein particles can withstand the mechanical and hydraulic stresses of a flowing liquid stream for extended periods is therefore a significant step toward genuine industrial applicability, moving the concept beyond batch-wise laboratory demonstrations.

Perhaps the most striking extension of the work is the creation of hybrid beads that combine purified enzymes with intact living cells. The researchers coupled the enzyme building blocks with cells of the bacterium Escherichia coli, producing composite materials in which two fundamentally different forms of biocatalysis coexist. Isolated enzymes excel at executing specific, well-defined reaction steps, but they often require cofactors or chemical energy supplied from outside. Living cells, by contrast, can regenerate cofactors, provide chemical energy through their metabolism, and synthesize intermediates that isolated enzymes cannot access. Until now, these two approaches have generally been treated as separate disciplines with separate toolkits.

“With the hybrid beads, we link two forms of biocatalysis, which are usually considered separately,” Niemeyer said. “They allow us to combine individual enzymes in a targeted manner and at the same time leverage the capabilities of living cells. This yields a material that unites the two approaches and is easy to work with.” The practical resilience of these hybrid materials proved remarkable. The beads remained catalytically active after more than four weeks of dry storage at room temperature, and even after five months in storage the functions of the cell-enzyme systems could still be confirmed. The researchers further demonstrated that viable cells could be recovered from the materials while retaining their genetic functionality, opening the possibility of recycling the biological component of the catalyst rather than discarding it after use.

The implications for sustainable manufacturing are considerable. Biocatalysis replaces chemical catalysts, many of which are toxic or derived from scarce metals, and it saves raw materials and energy because reactions proceed under mild conditions with high selectivity, generating fewer by-products and less waste. A modular, carrier-free bead format addresses the remaining barriers: enzymes become a storable, transportable, dosable commodity rather than a delicate solution that must be prepared fresh. The hybrid variant adds the ability to run energetically demanding or multi-step transformations that neither enzymes nor cells could perform efficiently alone, all within a single, handleable particle.

The KIT researchers see the first applications in the production of fine chemicals, flavoring agents, building blocks for pharmaceutical active ingredients, and other high-grade chemical products – markets in which product value is high, volumes are moderate, and the precision of enzymatic catalysis commands a premium. The findings are described in two publications in Advanced Materials and Advanced Functional Materials, including the paper “Programmable Carrier-Free All-Enzyme Beads for Modular Continuous-Flow Biocatalysis” by Jennifer Kühne and colleagues. If the modular bead concept proves itself at larger scales, the humble protein – nature’s own catalyst – may finally claim a much larger share of the chemical industry’s reactor volume, turning a technology long praised for its green credentials into one that is also genuinely practical.

Numerical climate and weather models have long been indispensable for predicting future conditions, ranging from global temperature trends to localized weather extremes. Yet, despite advances in physics-based simulations, achieving the full complexity of coupled Earth system processes — spanning vast spatial ranges and diverse timescales — remains a formidable computational challenge. AI offers a solution by efficiently emulating these traditionally resource-intensive models. More importantly, AI models trained directly on observational data sets are now surpassing classical approaches in performance, especially in weather forecasting. The WOW project aims to extend this success across the entire spectrum of Earth system phenomena.

At the core of the WOW initiative lies a sophisticated strategy to interconnect various AI models through their “latent spaces.” Latent spaces are multidimensional abstract representations learned by AI that capture essential features of complex data without explicitly modeling every detail. By coupling these latent representations, researchers anticipate more coherent and scalable synthesis of climate, atmospheric, hydrological, and ecological processes. This modular but integrated architecture promises to maintain high task-specific accuracy while ensuring global consistency across different environmental domains and time horizons.

The research team embraces the concept of “world models” from computer science, adapting it to the physical realities of Earth system science. Traditionally, world models allow AI to build internal representations of environments for prediction and decision-making. In this context, the world model will enable simulation of highly nonlinear interactions across the atmosphere, water cycle, land surface, and biosphere. For instance, the AI could elucidate how drought-induced soil moisture changes influence cloud formation patterns, which in turn feedback into regional climate variability, revealing interdependencies that have remained elusive to conventional models.

By integrating global climate emulators, AI-powered weather forecasting algorithms, and specialized models for localized extreme events such as wildfires and floods, WOW strives to create an end-to-end predictive framework for environmental dynamics. Each sub-model will initially be trained on task-specific data, optimized for specific phenomena. The novel challenge, and central innovation, is the coupling of these sub-models such that their outputs and internal states coherently inform each other, enabling emergent behavior modeling across scales — a leap forward from isolated or loosely linked simulations typical of today’s methods.

The interdisciplinary composition of the KIT team reflects the multifaceted nature of this endeavor, combining expertise in computer science, meteorology, climate research, and environmental science. This fusion is essential to develop new AI methodologies tailored specifically to environmental data and system dynamics. Significant advances in machine learning architectures, training regimes, and interpretability techniques will be pursued to ensure that the resulting models are not only powerful but also transparent and scientifically grounded.

One of the most compelling scientific frontiers opened by the WOW world model is in deciphering the complex feedback loops within the climate system. Nonlinear interactions and tipping points—such as those involving the atmosphere’s moisture budget, land surface processes, and biosphere responses—have historically defied precise quantification. With AI’s capacity to process vast multidimensional data and infer hidden relationships, the project offers potential breakthroughs in understanding and predicting cascading climate impacts that could inform resilience and adaptation strategies.

From a practical perspective, the ability to simulate localized environmental hazards within a globally consistent framework stands to enhance risk assessment and emergency preparedness. For example, robust AI modeling of wildfire dynamics in conjunction with regional climate trends and hydrological conditions could allow more accurate forecasting of fire-prone periods and support timely mitigation efforts. Similarly, improved flood prediction models integrated within the coupled Earth system AI framework would empower communities to better plan and respond to extreme weather events intensified by climate change.

Beyond the immediate applications in atmospheric and environmental sciences, the WOW project’s approach to modular yet interconnected AI modeling could inspire cross-disciplinary innovation. Complex systems outside Earth sciences — whether ecological networks, biological systems, or even socio-economic models — face analogous challenges in integrating diverse processes across scales. Efficient AI coupling of sub-models may thus represent a transformative computational paradigm for multiple scientific domains, accelerating insights and discovery.

The WOW project is generously funded by the Carl Zeiss Foundation with a budget of six million euros over five years, reflecting the high societal and scientific value placed on this research. By pushing the envelope of AI in climate science, the project exemplifies KIT’s commitment to tackling urgent global challenges through cutting-edge, interdisciplinary innovation. The ultimate vision is a scalable, adaptable AI system that captures the delicate interplay of Earth’s dynamic processes and provides actionable knowledge to navigate a rapidly changing planet.

Through this AI-driven world model, KIT aims not only to refine our predictive capabilities but also to deepen our fundamental comprehension of Earth’s complex systems. By simulating emergent environmental phenomena with unprecedented integration and nuance, the researchers hope to uncover previously hidden climatic and ecological relationships. This, in turn, enriches scientific understanding and equips policymakers and society with the tools necessary to make informed decisions about climate mitigation and adaptation strategies.

As climate change accelerates and inspires urgent calls for sustainability, projects like WOW demonstrate how frontier technologies such as AI are indispensable in driving the science forward. By bridging data-driven AI methods with physical modeling expertise, and uniting micro-scale event forecasting with macro-scale systemic understanding, KIT positions itself at the forefront of climate innovation. The fusion of AI and Earth system science in this initiative not only promises new explanatory frameworks but could catalyze a revolution in how humanity anticipates and responds to planetary change.

In the words of Professor Dr. Oliver Kraft, Vice President for Academic Affairs at KIT, “This award celebrates Dr. Xu’s visionary scientific achievements rooted in a socially relevant domain. Her work on cooling technologies addresses a fundamental need that profoundly intersects with societal welfare, economic vitality, and ecological sustainability.” Dr. Kraft highlights that the award not only recognizes Dr. Xu’s scientific excellence but also emphasizes the indispensable contributions of female scientists in driving global research and technological development forward.

Dr. Jingyuan Xu’s research group at KIT, the ZEco Thermal Lab, established in 2021 under her leadership, concentrates on the development of zero-emission, eco-friendly heating and cooling systems through the exploitation of the elastocaloric effect. The elastocaloric phenomenon refers to the property of certain solid-state materials that undergo temperature changes when subjected to mechanical stress and subsequent release, enabling cooling or heating without relying on chemically harmful refrigerants. This represents a transformative leap away from traditional vapor compression systems, which contribute significantly to global greenhouse gas emissions through their use of high-global warming potential (GWP) fluids.

The implications of Xu’s work are particularly momentous considering the global prevalence of cooling units. Over three billion air conditioning units are in operation worldwide, consuming approximately 20 percent of global electricity. Current predominant technologies are entrenched in 19th-century mechanistic designs—compression refrigeration relying on volatile refrigerants with severe environmental ramifications. By pioneering elastocaloric-based alternatives, Dr. Xu’s research confronts these challenges head-on, offering scalable solutions that could dramatically reduce carbon emissions and energy consumption.

Within the ZEco Thermal Lab, diverse applications are under exploration, ranging from micro-level cooling solutions, such as those needed in sensitive electronic devices and microprocessors, to large-scale appliances including residential refrigerators and commercial air conditioning systems. This multifaceted approach illustrates the adaptability of elastocaloric materials and devices, making them feasible replacements for traditional refrigeration technologies in multiple sectors. Xu emphasizes the necessity of reimagining cooling technology from foundational physics principles to address the urgent climate emergency effectively.

Dr. Xu expressed profound gratitude for the recognition, remarking, “This award affirms the value of my research and I am hopeful it serves as an inspiration to young women worldwide to engage in scientific endeavors addressing the planet’s critical challenges.

Remarkably, seven laureates stemming from this initiative have achieved Nobel Prize recognition, underscoring its profound impact. Within Germany alone, more than 50 early-career female researchers have been supported, signaling a critical advancement towards gender parity in STEM fields.

From a technical standpoint, the elastocaloric effect utilized by Dr. Xu’s team is part of a class of solid-state cooling technologies often termed “caloric effects,” which also include magnetocaloric, electrocaloric, and barocaloric phenomena. These effects rely on reversible entropy changes in materials—driven by external stimuli such as stress or magnetic fields—to produce cooling with high efficiency. Unlike conventional vapor compression systems, elastocaloric cooling eliminates the environmental drawbacks of greenhouse gases, such as hydrofluorocarbons (HFCs), which have long been the standard refrigerants but are significant contributors to global warming.

KIT stands at the forefront of such pioneering research, integrating expertise across disciplines to address energy efficiency and environmental sustainability. As “The Research University in the Helmholtz Association,” KIT mobilizes over 10,000 employees with a diverse academic focus spanning natural sciences, engineering, economics, and humanities. With an enrollment of approximately 22,800 students, the institute is committed to training future leaders capable of scientific innovation and social responsibility. The activities of the ZEco Thermal Lab perfectly embody KIT’s mission to bridge high-level scientific insights with real-world applications for societal benefit.

The urgency for alternative cooling technologies extends beyond environmental concerns. Rising global temperatures and increasing urbanization have heightened dependence on air conditioning, exacerbating energy demand peaks and straining power grids. Thus, Dr. Xu’s research not only offers ecological advantages but also presents pathways to enhance energy security and reduce operational costs for consumers worldwide. Her group’s ongoing efforts to optimize elastocaloric materials—improving their fatigue resistance, thermal conductivity, and mechanical performance—aim to overcome current barriers to commercialization.

Moreover, Dr. Xu’s work aligns with international efforts to phase down the use of high-GWP refrigerants, as mandated by agreements such as the Kigali Amendment to the Montreal Protocol. By advancing solid-state and refrigerant-free cooling solutions, the ZEco Thermal Lab is contributing directly to global climate action goals. The successful deployment of these technologies on a broad scale could revolutionize how heating and cooling systems are designed, offering a sustainable alternative that integrates seamlessly into existing infrastructure.

Looking forward, the interdisciplinary and applied nature of Xu’s research invites collaboration from materials science, mechanical engineering, and environmental policy sectors. To maximize impact, the lab prioritizes not only technological innovation but also lifecycle assessments and economic viability studies—key components for ensuring that the resulting cooling devices are accessible and sustainable in diverse markets.

Dr. Jingyuan Xu’s recognition through the “For Women in Science” award highlights the critical intersection of gender, scientific excellence, and environmental stewardship. As the fight against climate change intensifies, the contributions of women scientists like Dr. Xu demonstrate that innovative research—when paired with inclusive support and visibility—can drive transformative solutions for global challenges. Her achievements serve as a beacon for emerging researchers and reinforce the message that the future of science and technology depends on diverse perspectives dedicated to the planet’s well-being.

Manuel Krannich operates at the cutting edge of algebraic and geometric topology, a realm where the intrinsic properties of spaces that remain invariant under continuous transformations are meticulously studied. His fascination lies primarily with manifolds, intricate structures that locally resemble Euclidean space but globally encapsulate complex shapes akin to the earth’s curvature represented through overlapping maps. His groundbreaking project navigates the interface of manifold theory and functor calculus—a sophisticated mathematical framework that investigates the relationships and transformations between different categories and algebraic structures.

Functor calculus, originally inspired by classical calculus, serves as a powerful tool to analyze functors between categories by approximating them through polynomial-like stages. When applied to manifolds, it unlocks a deeper understanding of their symmetries and structural behaviors in high-dimensional spaces. Krannich’s research delves into the subtle interplay between these symmetries and the algebraic laws governing them, offering new perspectives in both pure mathematics and potentially influencing theoretical physics, particularly in fields like string theory and quantum topology.

Krannich’s approach is notably problem-oriented and methodological innovation lies at the heart of his endeavors. Unlike conventional research that often follows established pathways, his work involves the synthesis of diverse techniques from algebra, geometry, and topology. This synthesis is not merely additive; instead, it reveals unexpected connections and constructs new mathematical apparatuses that deepen our understanding of manifold structures and their algebraic underpinnings. Such a strategy is essential in tackling complex mathematical phenomena that resist straightforward classification or explanation.

The trajectory of Krannich’s career reveals a comprehensive and international academic formation. After receiving his Bachelor’s and Master’s degrees from KIT, he penned his doctoral thesis at the University of Copenhagen, focusing on characteristic classes of bundles of manifolds—objects that encode essential geometric and topological information. His postdoctoral years were spent at internationally renowned institutions, including the University of Cambridge and the University of Münster, where he further honed his expertise in algebraic and geometric topology. In 2022, he solidified his academic role with a junior tenure-track professorship at KIT, leading the Algebraic and Geometric Topology group at IAG.

The ERC Starting Grants aim to empower promising young scientists embarking on independent research careers by providing substantial financial backing and institutional recognition. The 2025 round was notably competitive, with 3,928 applications submitted across Europe. Only 478 projects received funding, reflecting a stringent acceptance rate near 12.2%. Germany was among the leading countries in the program, with 99 recipients. This selectivity underscores the high standards and the transformative potential of the chosen projects, which are envisaged as generating breakthroughs across a wide array of scientific disciplines.

Krannich’s MaFC project stands at the crossroads of manifold theory and higher algebra—fields that underpin much of contemporary mathematics. Manifolds serve as abstract generalizations of curves and surfaces, but in high dimensions, they become vehicles for exploring intricate spatial phenomena and forms. The project’s focus on functor calculus affords an algebraic lens on these complex structures, potentially revealing new invariant properties and symmetry relations. These insights not only enrich theoretical knowledge but may also impact computational topology and geometric analysis.

A critical innovation in Krannich’s work involves the construction of novel invariants of high-dimensional manifolds, linked intricately to the functorial properties of associated algebraic structures. These invariants help classify manifolds and understand their deformation spaces—an area that interfaces with gauge theory, surgery theory, and homotopy theory. The unification of these areas through the technique of functor calculus presents a promising pathway to resolving longstanding open problems in the classification and analysis of manifolds, many of which have resisted previous approaches.

The interdisciplinary nature of Krannich’s research highlights the trend towards the integration of mathematical subfields. By bridging pure algebraic concepts with geometric intuition, the MaFC project exemplifies a paradigm where manifold topology is no longer an isolated discipline but part of a broader algebraic ecosystem that includes category theory, operad theory, and homotopical algebra. Such frameworks provide a language and toolkit to unravel high-dimensional phenomena with greater precision and conceptual clarity.

Beyond theoretical significance, the findings anticipated from the MaFC research may have downstream effects on theoretical physics, especially in areas that model spacetime and fields using manifold structures. The refined understanding of symmetries and algebraic behavior in high-dimensional spaces is key to developing frameworks in quantum field theory, topological quantum computing, and string theory. Thus, Krannich’s research holds the promise of crossing discipline boundaries from pure mathematics to fundamental physics.

The 1.5 million euro funding over five years will enable Krannich to assemble a dynamic research team, procure computational resources, and foster collaborations that accelerate innovation. The ERC grant not only endorses his competence but provides a platform for sustained exploration of mathematically rich, conceptually demanding problems. This support amplifies the impact of his research, increases visibility within the international mathematical community, and cultivates future experts trained under his guidance.
