Underground microbial life more stable than expected
Research
Eawag
Microbial communities living deep underground in the groundwater of Lavey-les-Bains remain surprisingly stable throughout the year, even though the composition of the water changes seasonally. This is the finding of a study by Eawag researchers that contributes to a better understanding of geothermal systems and microbial life deep underground.
City trees provide cooling even in extreme heat
Research
WSL EPFL
Plane trees in cities have an important cooling effect even in extreme heat, according to a new study conducted by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) and EPFL. The next step is to identify which tree species are particularly effective at cooling.
AI paves the way towards green cement
Research
PSI
The cement industry produces around eight percent of global CO₂ emissions – more than the entire aviation sector worldwide. Researchers at the Paul Scherrer Institute PSI have developed an AI-based model that helps to accelerate the discovery of new cement formulations that could yield the same material quality with a better carbon footprint.
Bacteria eat bacteria
Research
Eawag ETH Zurich
Many bacteria produce a protein complex to inject poison in their neighbouring cells. This was previously thought to eliminate their competitors. But now researchers at Eawag and ETH Zurich have shown: The killer bacteria can act as biological predators that feed on their prey.
What ETH glacier researchers know about the collapse of the Birch Glacier
Research
ETH Zurich
On Wednesday, the glacier known as Birchgletscher collapsed under the weight of rock and debris from rock avalanches on Kleines Nesthorn. In a factsheet, ETH researchers explain the background to the catastrophic collapse that buried the village of Blatten.
Earthworms avoid tyre abrasion
Research
Eawag EPFL
Tyre abrasion gets from the road into adjacent soils and affects soil organisms. A joint study by the Ecotox Centre, the aquatic research institute Eawag and the EPFL now shows that earthworms avoid soil that is heavily contaminated with tyre particles. However, the particles had no negative effects on the survival and reproduction of the animals.
