Amphipods in Swiss waters are exposed to insecticides, pharmaceutical residues and other trace substances, and accumulate these in their bodies. However, when water-treatment plants are upgraded, practically no trace substances are found in these organisms according to a new study carried out by Eawag researchers. Read more

Reconstruction of the city of Aventicum on Lake Murten, former capital of Roman Switzerland. The picture is taken from the book “Aventicum — A Roman Capital City” by Daniel Castella et al (2015).

When a population grows quickly and farms intensively, the environment often suffers. This is not only true today, but was also the case as early as Roman times. Evidence of this has been found by Eawag researchers in sediments in Lake Murten. Read more

Wenfeng Liu received the Otto Jaag Water Protection Prize 2018 at the official ceremony on 17 November 2018.
November 21, 2018

Once again, an Eawag doctoral candidate is awarded the Otto-Jaag Water Protection Prize: Wenfeng Liu was honoured for his dissertation "Modelling Global Water-Food-Environment-Trade Nexus in the Context of Agricultural Intensification". The Otto Jaag Water Protection Prize honours outstanding dissertations and master's theses at ETH Zurich in the field of water protection and hydrology. Read more

Philipp Dermond carries out a muscle and scale test and implants a chip in the stomach cavity of an anaesthetised sea trout. The researchers will then be able to track whether the fish from the stream migrate to the sea or whether they ... (Photo: FIBER)

There’s a new face at the fishing advisory office (FIBER) in Kastanienbaum: Philip Dermond is taking over from Sébastien Nusslé and is thus the new co-director with Corinne Schmid. Philip Dermond transferred in October from the Fish Ecology and Evolution department at Eawag to FIBER. Read more

Scientists at Eawag and Zurich University have synthesised for the first time the amounts of carbon transported between many different ecosystems. According to this global synthesis, spatial flows of carbon can be very large – and their significance has previously been underestimated. Read more

Many infectious viruses are transferred to humans from water or other liquids. A microbiologist at Eawag has now investigated how high the risk of infection is when someone comes into contact with polluted water. Read more

Michael Berg, head of the Eawag Water Resources and Drinking Water department, has been appointed adjunct professor with the School of Civil Engineering and Surveying at the University of Southern Queensland (USQ). His appointment is linked to becoming one of the members of the “UNESCO Chair on Groundwater Arsenic”, which is based at the USQ. Read more

November 8, 2018

It is common among many species for individuals to move around during their lifetime in order to settle in better adapted habitats, a process known as dispersion by ecologists. In order to improve scientific predictions of the future of biodiversity in the face of global changes it is very important to understand the mechanisms of dispersion. Read more

Using tiny DNA fragments, even rare species are discovered in bodies of water (Photo: Pixabay).
November 6, 2018

Bits of genetic material in rivers make it possible to detect the organisms living in them – without having to collect these and examine them under the microscope. Researchers at Eawag, the ETH and the EPFL have now developed a computer model that with the help of single DNA measurements even simulates exactly where and how often the species are present in bodies of water.

Probiotics – live bacteria with beneficial effects on human health – are believed to hold out great promise for certain therapeutic applications. But do these bacteria remain viable when they are frozen or freeze-dried for storage? Eawag’s expertise in drinking water microbiology enabled to it provide valuable support for a study of gut microbes carried out in the Food Biotechnology Laboratory at ETH Zurich. Read more
