The chemical industry is involved in virtually every product we use in daily life. However, it is also responsible for a significant share of global CO₂ emissions. ETH researcher Ronja Rappold wants to change that. As an ETH Pioneer Fellow, she is developing microorganisms that convert CO₂ into useful chemicals as part of her planned ETH spin-off Teno Bioworks.
The rock avalanche of May 2025 didn’t just bury the village of Blatten – within seconds, it also fundamentally transformed the entire landscape.
