Implementation of the Montreal Protocol has successfully prevented depletion of the stratospheric ozone layer and associated increases in levels of UV-B radiation at the Earth’s surface. But many questions remain to be answered – for example, how does climate change affect the exposure of terrestrial and aquatic ecosystems to UV radiation? This is one of the questions discussed in a review article, co-authored by former Eawag scientist Barbara Sulzberger, which was recently published in Nature Sustainability. Read more

The 3RCC award has been conferred on two Eawag researchers by the 3R Swiss Competence Centre (3RCC) for their outstanding research work. For the first time ever, the researchers managed to obtain ISO certification for a toxicity test using cultured fish gill cells, thanks to their project work in this area. This represents a milestone in the promotion of alternatives to animal experiments. The prize was awarded on September 2nd in Bern. Read more

The energy strategy calls for a further expansion of hydropower. This puts pressure on Swiss water bodies and water landscapes. At today's Eawag Info Day, some 200 experts from practice, research and administration will discuss how the various interests in water can be met in a sustainable manner and where the competition between these interests calls for priorities to be set. The Eawag researchers will demonstrate that it is not only a question of technical solutions, but also of social acceptance, for example when measures in favour of water ecology lead to an increase in the price of electricity.

Amphipods are among the most important invertebrate organisms in water. They have central ecological functions, for example as food for fish or in the degradation of leaves. Nevertheless, surprisingly little is known about these animals, which are between a few millimetres and a few centimetres in size. And despite very different requirements, the species are hardly differentiated in water monitoring. Read more

On 1 September 2019, Benoît Ferrari will take over as interim director of the Ecotox Centre. Benoît Ferrari is an expert on the ecotoxicity of sediments and has been group leader for sediment and soil ecotoxicology at the Ecotox Centre in Lausanne since 2013. The current director, Inge Werner, will remain with the Ecotox Centre on a part-time basis until 2021. Read more

Not only women, but also most men, find that men more often walk right into a trap and are gender biased. More than twice as many women as men think that they are disadvantaged because of their sex. Likewise, almost twice as many women as men approve of a quota for women in academic positions. This is the result of an evaluation of a questionnaire published in the magazine Earth and Space Science. Read more

Swiss groundwater contains numerous pesticide degradation products. This has been discovered by an extensive screening by Eawag and ETH Zurich. The transformation products (metabolites) originate predominantly from pesticides from agriculture. Read more

Ebola is a deadly viral infection that has so far mainly been present in Central and West Africa. Many people in those regions are either unfamiliar with the disease, do not believe in it, or don’t know how to prevent infection. For this reason, UNICEF was active in The Gambia, West Africa, among other places, between 2014 and 2016, running information campaigns on how to prevent the spread of Ebola. Read more

Phosphate supplies are limited and found in only a few countries. Mining and transport of this nutrient are costly. It is therefore becoming increasingly important that phosphorus be recovered and reused regionally, and Switzerland, with a functioning phosphorus recycling economy, can lead the way. Read more

A team of ten female cyclists is currently undertaking the hardest ride of their lives, riding all stages of this year’s Tour de France route—albeit one day ahead of the men’s race. Amongst the cyclists is Sara Beck, a postdoc in the Environmental Microbiology department. Read more

Without phosphorus there would be no life; however, the mineable quantities are limited. The element was first described 350 years ago. This week, some 200 experts are meeting in Zurich to discuss the future of phosphorus. Read more

When animals migrate into an ecosystem, the ecosystem turns into a temporary land of milk and honey for predators. But novel findings from a recent study on local fish migration patterns in northern Europe indicate that even when animals migrate out of an ecosystem, their absence has an effect on food webs.

Some insecticides, such as the neonicotinoids, have an effect on the nervous systems of organisms. But not only, as shown by the results of a new study in which Eawag scientists took part. And: the resulting damage can be very different, depending on the species of fish. Read more

For 13 years, the "building" foundation has been committed to promoting the next generation of engineers in the construction industry, which also includes the Building Award for remarkable and innovative engineering achievements in construction. This year's award in the "Research and Development" category goes to NEST, the modular research and innovation building of Empa and Eawag. Read more

Since the last ice age, stickleback have managed to emerge from the sea to colonise many freshwater waterbodies. Genetic analysis by Eawag researchers and colleagues from the University of Bern and the National Institute of Genetics in Shizuoka, Japan, now demonstrate that they achieved this thanks to additional copies of a metabolism gene.

For the first time ever, a toxicity test with cultured gill cell lines from fish has been ISO-certified. The test is used to determine the acute toxicity of water samples and chemicals to fish. This is an important milestone because there is a lack of recognised alternatives to experiments with live fish. Read more
