All that's left behind Research ETH Board Wastewater-based epidemiology can provide valuable insights into a population’s overall health. By analysing samples gleaned from wastewater, Eawag is helping medical experts shed new light on the prevalence of coronavirus infections during the pandemic. But the possibilities don’t end there.

Research WSL There are more than 1300 tree species in Swiss cities, while our forests are home to only 76, according to a study by the WSL. This means that introduced forest pests or diseases also find significantly more potential hosts in cities – and could spread from there into the forests. Forest Environment Ecosystem Biodiversity Biology Biology Planets contain more water than thought Research ETH Zurich Most of a planet’s water is generally not on its surface but hidden deep in its interior. This affects the potential habitability of distant worlds, as shown by model calculations of researchers at ETH Zurich and Princeton University.
