November 18, 2020Researchers Juliane Hollender, Ole Seehausen, Bernhard Truffer and Urs von Gunten from the aquatic research institute Eawag are among the "highly cited researchers 2020".

November 12, 2020In the journal ZooKeys, a group of scientists from Eawag and Bern University have described seven whitefish species endemic to the Bernese Oberland lakes – including four not previously described scientifically, two of which have only been identified as distinct species in the last few years. In Switzerland, the whitefish diversity of Lakes Thun and Brienz is possibly matched only by that found in Lake Lucerne; and in deep lakes of this kind further surprises cannot be ruled out.

November 3, 2020In agricultural areas, large volumes of water from fields, roads and paths drain directly into streams via manholes and other forms of artificial drainage. These shortcuts also transport pesticides into surface waters – and, according to a new study, in significantly larger quantities than was previously assumed.

October 29, 2020When the wind on Lake Biel blows from the south-west and it rains heavily, large quantities of sediment are washed out of the River Aare into the lake. Since the south-west wind also influences the circulation in the lake, the wind direction determines to a large extent where the sediment is deposited in the lake, namely along the eastern shore towards Biel – an important finding for identifying areas at risk of landslides.

October 22, 2020The findings of a new measurement campaign on Lake Kivu in Africa show that, contrary to previous assumptions, the methane concentration in the water is relatively stable or increasing only very slowly. Therefore, the risk of a sudden gas eruption from the lake is currently not increasing.

October 15, 2020Exploration and utilisation of resources from the world’s oceans is not equally distributed across the globe. Although many of these resources originate in the Global South, they are mostly being researched by just a few countries from the North. Accordingly, this is also where most of the benefits and profits are flowing to, despite the Convention on Biological Diversity. This was the finding of an analysis of literature from the last 50 years.

October 9, 2020Whether a lake was once polluted with excess nutrients is reflected even decades later in the community of bacteria living on these nutrients in the sediment. However, there is still surprisingly little research into how microbes in the sediment cooperate.

October 6, 2020The new digital tool PlaNet makes it easier for municipalities to identify important project partners but also critical voices in complex environmental and infrastructure projects. In this way, it helps them to set up participatory processes in a professional manner.

October 1, 2020There are solid psychological explanations for how consistently we follow the behaviour rules to prevent the spread of Coronavirus, such as the expectations we have towards ourselves and others. These are the findings of a representative survey, the results of which can now be used to optimise public information campaigns.

September 29, 2020Circular economy also holds great potential when it comes to wastewater. At NEST, Eawag is conducting research on decentralized wastewater treatment with the aim to use wastewater as a source of nutrients, energy and water. Important partners are Keramik Laufen AG with the urine separation toilet "Save!" and the Eawag Spin-off Vuna with the liquid fertilizer made of urine "Aurin".
