Phylogenetic tree reveals: new species of whitefish have emerged in every lake

For a long time professional fishermen have known that there is not just one whitefish species in Switzerland, but a whole range of species each with their own specialization and local name. Researchers have now analysed the entire genome of the various whitefish and shown how specialists have all developed independently of each other in each lake region. Read more

Ecological stability of lakes declining globally over time

Of over a thousand lakes studied worldwide, about one in ten shows strange behaviour. In general, there is an increasing tendency for aquatic ecosystems to tip over. The ecological stability of lakes is decreasing, especially in regions with low GDP and large human populations. Read more

Biological approaches to combat Legionella

Throughout Switzerland, infections with bacteria of the genus Legionella are increasing significantly. Researchers at Eawag have now outlined how the growth of these microbial inhabitants of drinking water systems could be curbed with the help of other organisms. Read more

Fluoride in groundwater: global map shows all risk areas for the first time

As an additive in toothpaste, it protects our teeth from decay. But when fluoride occurs in nature in larger quantities and accumulates in groundwater, it can become a hazard for our health. For the first time, Eawag scientists have produced a detailed map of global fluoride contamination in groundwater and shown which regions of the world are particularly affected. Read more

Monitoring SARS-CoV-2 mutations in wastewater

A study published today in Nature Microbiology highlights the great advantage of wastewater monitoring as being rapid, unbiased and cost-effective: the detection of genomic variants of SARS-CoV-2 in wastewater offers an early alert and can be based on fewer samples as compared to clinical samples.

Industrial wastewater: treatment plants do not eliminate all contaminants

Even though industrial wastewater is treated at state-of-the art plants, the sheer variety of synthetic organic compounds from the chemical and pharmaceutical industry which end up in surface waters are seriously underestimated. This is shown by a new study carried out by Eawag and ETH Zurich. Read more

Virtual fish instead of animal testing

As part of a new national research programme that aims to replace animal experiments in research, the National Science Foundation is supporting a project at Eawag. This opens up new possibilities for determining the toxicity of chemical substances based solely on tests with cultured cells and computer models. Animal experiments could thus be replaced.
