November 21, 2017As part of the artists-in-labs programme run by the Zurich University of the Arts, two artists from Saudi Arabia are currently artists-in-residence at Eawag for three months. Zahrah Alghamdi is working in the Aquatic Ecology department and is looking at running waters and their physical properties as well as their emotional and poetical aspects, while Muhannad Shono is a guest of the Environmental Microbiology department, where he is exploring parallels between microorganisms and humans.

November 20, 2017Tomorrow, 21 November 2017, will be Switzerland’s first ever Digital Day, with around 40 prominent businesses and institutions holding more than 80 events around the country to show what the significance of digitalisation will be for them and for Switzerland’s future. The President of the Federal Council, Doris Leuthard, will open the Digital Day at an event in Zurich’s main railway station, which will also be attended by federal minister Johann Schneider and Eawag Director Janet Hering.

November 2, 2017Christian Stamm and Alfred Johny Wüest are lecturing along with other academics and practitioners in a new online course on “Water in Switzerland”, run by the University of Zurich. The course, addressed to the public, examines how this element affects various aspects of life in Switzerland.

October 27, 2017In Switzerland – not to mention the rest of Europe and the United States – freshwater fish are falling victim to a deadly disease that is rampant in the summer and dormant in the winter. It is caused by a parasite that thrives in rivers and attacks salmonid fish in particular. Researchers from EPFL, Eawag and University of Bern have come up with a mathematical model for predicting outbreaks as part of a three-year joint research program.

October 26, 2017Humans have so profoundly altered the Earth that, some scientists argue, our current geologic epoch requires a new name: the Anthropocene. But defining the precise start of the era is tricky. Would it begin with the spread of domesticated farm animals or the appearance of radioactive elements from nuclear bomb tests?

October 23, 2017Although bacteria are an inevitable – and important – component of drinking water, the colonization of pipes by pathogenic organisms can lead to microbiological quality problems. However, according to an Eawag/HSLU project co-funded by the Commission for Technology and Innovation (CTI), various measures can be taken to minimise this risk.

October 18, 2017Compared to other foodstuffs, Switzerland’s drinking water shows low levels of contamination with antibiotic-resistant bacteria or resistance genes. This was demonstrated in a study of eight drinking water systems carried out by Eawag researchers on behalf of the Swiss Gas and Water Industry Association (SVGW) and water suppliers.

October 16, 2017In a laboratory experiment, Eawag ecologists studied how the pond snail Lymnaea stagnalis is affected by heatwaves, which are expected to become more frequent as a result of climate change. Snails exposed to temperature stress showed a greater investment in reproduction, egg production increasing by 60 per cent on average.

October 12, 2017According to a study funded by the Federal Office for the Environment, pesticides or transformation products can persist in soils for a decade or more. In the study, Eawag and Agroscope scientists analysed topsoil samples collected from 14 agricultural sites between 1995 and 2008 as part of the Swiss Soil Monitoring Network programme.

October 10, 2017A study just published by Eawag scientists shows that gold and silver each amounting to around CHF 1.5 million a year are lost via effluents and sludge from wastewater treatment plants in Switzerland. The concentrations measured do not pose risks to the environment – and recycling would not be economically worthwhile. However, the study also produced surprising findings on other trace elements in wastewater, including rare earth metals such as gadolinium and the heavy metal niobium.
