The lakes of East Africa are home to a surprising number of different cichlid species. This level of biodiversity has developed partly due to hybrids that managed to take over new ecological niches in their habitats, according to recent research carried out by scientists at the Swiss Federal Institute of Aquatic Science and Technology, Eawag, and the University of Bern.

Invertebrates on the beds of water bodies are observed closely, for they serve as indicators for the ecological status of running waters. A new Swiss-wide study by the aquatic research institute Eawag shows which species are especially good indicators, and how the monitoring and management of surface waters can be further improved.

It's World Toilet Day today. What may sound curious is intended to draw attention to a serious problem. Because worldwide, one in three people lack access to appropriate sanitation. In the Blue Diversion Autarky project, researchers are developing an off-grid toilet, with on-site treatment allowing valuable resources to be recovered.
