A new theory supports the controversial hypothesis that the planets affect solar activity. It puts forward a mechanism by which the very small influence of the planets could exert its rhythm on such a large system as the Sun. If the theory is confirmed, it could possibly be used to predict solar activity more accurately. This would be of great interest, as large solar flares can cripple electronic infrastructure.

Each year at Eawag, around 160 Master’s and Bachelor’s students are supervised and often directly involved in research projects. Again and again, this collaboration – as well as Eawag’s flat hierarchies and interdisciplinary culture – leads to outstanding Master’s theses.

A comprehensive inventory of Swiss glacial lakes shows how the lake landscape in the high mountains has changed since the end of the Little Ice Age.

Open Science is an important development in science - open access to the results of research. Eawag supports these and makes a growing part of its research data, including descriptions, images and even software, available publicly and free of charge on the Eawag platform ERIC or, in special cases, on discipline-specific, international databases. ERIC complements the long-standing platform DORA for scientific publications.

Eawag’s practice-oriented courses (known as PEAK) provide training for professionals. Isabelle Schläppi of the PEAK Office looks back over a year marked by the COVID-19 pandemic.

Last week, around 25 guests were able to witness live - and in keeping with Corona- how the large silver key to the new Eawag building symbolically changed hands.

Groundwater is also an ecosystem, but little is known about the biodiversity underground. Eawag researchers have now documented the diversity of life in Swiss groundwater in a pilot study – and discovered previously unknown species of amphipods in the process. Here they relied on a citizen science approach.

The OECD gives the green light to the fish cell line assay developed at Eawag. This paves the way for companies and authorities around the world to determine the environmental toxicology of chemicals without having to resort to animal testing.

Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides such as lindane or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Eawag and Empa used these bacteria to generate enzymes that can break down these dangerous chemicals.

Formerly widespread, native crayfish in Switzerland are now highly endangered. With support from Eawag, experts are doing everything they can to preserve the secretive river dwellers.
