February 18, 2025Last week, the ‘Blue Summit Switzerland’ water conference was held at Reichenau Castle. Themed ‘Switzerland's water reservoir also needs new solutions!’, more than 100 participants, including 20 national and cantonal politicians, attended.

February 13, 2025Each year, tens of thousands of chemicals enter the market and ultimately the environment. While most of these compounds undergo safety testing before approval, their long-term effects on wildlife remain difficult to predict. To better estimate their potential threat for ecosystems, researchers at Eawag have explored biochemical signatures that indicate the level of chemical stress suffered by fish.

February 12, 2025The conditions in mountain huts often make it difficult and impractical to meet the requirements for wastewater treatment. A new approach to assessing cleaning performance could change that.

February 11, 2025The public can take part in a survey to decide on the names of two fish species discovered by Bárbara Calegari and her colleagues. In this interview, the biologist explains where they live and how to make the diversity of our waters visible.

January 29, 2025Elena Gimmi received an ETH Medal for her dissertation on the influence of bacterial “bodyguards” on the co-evolution of the black bean aphid and its natural enemy the parasitoid wasp.

January 9, 2025On the Pic du Midi in the Pyrenees, ETH researchers have analysed particulate matter, clouds and rainwater for traces of arsenic. Using newly developed measurement methods, they have elucidated the transport pathways of the environmental toxin in the atmosphere.

January 7, 2025A series of cartoons is intended to provide food for thought across disciplines in a humorous way and invite discussion.

December 17, 2024Today, over 60 experts from research, federal and cantonal administration, the police, politics and hospitals are meeting to discuss the current status and future of wastewater monitoring in Switzerland. The current trends: a seasonal increase for influenza and the RSV virus, stagnating or even declining for coronavirus. We spoke to environmental engineer Christoph Ort, who, together with environmental microbiologist Tim Julian, established the field of wastewater-based epidemiology at Eawag and - in cooperation with external experts - is constantly adapting it.

December 12, 2024Plants and water can mitigate heat in cities. Using Zurich as a case study, Eawag researchers tested a climate model which indicates how large the effect of green and blue spaces is. The model supports urban planning and shows where improvements would be particularly effective.

December 10, 2024In view of biodiversity loss, it is important that early-career researchers get involved not only in science but also contribute to biodiversity policy.
