March 2, 2021In Lake Constance, sticklebacks are occupying increasingly varied habitat types – in recent years even including the open and deep waters of the lake. In an Eawag review undertaken as part of the “SeeWandel” project, these uniquely diverse ecological adaptations are explained in terms of renewed contact between three stickleback lineages – including one originating from the Baltic region, whose genetic material is as yet rarely observed in other Swiss lakes.

February 25, 2021Copepods (minute crustaceans with paddle-like feet) can differentiate between disturbances in water generated by nearby organisms and turbulence caused by wind or waves – an ability which helps them to find mates. It had previously been assumed that turbulent conditions would impede the quest for mates.

February 23, 2021A new fact sheet highlights the opportunities and challenges associated with greywater.

February 18, 2021A new simulation study shows that climate change risks significantly altering water temperature, ice cover and mixing of many Swiss lakes. Mid altitude lakes are especially under pressure, running the risk of completely losing ice cover and no longer fully mixing twice per year. Such a change would have fundamental consequences for the functioning of lake ecosystems.

February 17, 2021Sam Derrer has been head of vocational training at Eawag for ten years, so he knows exactly how varied training is and how apprentices are encouraged and challenged at the research institute.

February 12, 2021A community of sulfur bacteria grows in the northern basin of Lake Tanganyika and plays a key role in the lake's nitrogen cycle. With climate change, the deep blooms could expand southward, a new study shows. This could have drastic consequences for regional fisheries. 

February 11, 2021Today is the International Day of Women and Girls in Science. Eawag has long attached great importance to the engagement of women and the promotion of female careers.

February 9, 2021Beavers are master builders that reshape aquatic landscapes with their dams and lodges. The environments they inhabit experience an increase in the biodiversity of aquatic organisms, for example. Now, for the first time, an Eawag study from the wine-growing region known as “Zürcher Weinland” has shown that this is also true for streams in areas given over largely to agriculture. The rodents could therefore be interesting partners when it comes to enhancing bodies of water.

February 4, 2021Surfaces which are frequently touched by many different people may be contaminated with the coronavirus, but the risk of infection via this route is low. However, regular collection of samples from door handles, buttons or keypads could be useful for monitoring the course of the pandemic.

January 29, 2021For three months, an extended family in South Africa tested the standalone Autarky toilet cubicle. Everyone was very happy with the quiet hideout.
