An Empa team has now developed a translucent glass brick with good insulation properties thanks to aerogel, which can even be used for load-bearing elements. This makes it possible to build aesthetic, translucent walls that reduce the need for artificial lighting inside the building.

DNA traces in groundwater
|
An Eawag study shows that a large variety of living organisms leave their DNA traces in groundwater – which also depends on the land use in the catchment area. In future, these biological parameters could be used to assess groundwater quality.
