Fluoride in groundwater: global map shows all risk areas for the first time
Fluoride in groundwater: global map shows all risk areas for the first time
As an additive in toothpaste, it protects our teeth from decay. But when fluoride occurs in nature in larger quantities and accumulates in groundwater, it can become a hazard for our health. For the first time, scientists have produced a detailed map of global fluoride contamination in groundwater and shown which regions of the world are particularly affected.

Don't attack the Energy Strategy with simplified assumptions
Don’t attack the Energy Strategy with simplified assumptions
An ETH risk researcher has concluded that Energy Strategy 2050 doesn't work. The Energy Science Center at ETH Zurich disagrees: extensive research shows that the energy transition is feasible and makes sense, writes Gabriela Hug together with her ESC colleagues. Earlier this month, the Neue Zürcher Zeitung newspaper reported that huge dependence on electricity imports in winter was imminent if the Swiss federal government went through with the Energy Strategy including nuclear phase-out.

Ozone depletion over North Pole produces weather anomalies
Ozone depletion over North Pole produces weather anomalies
Researchers from ETH Zurich have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average - or too wet. Many people are familiar with the hole in the ozone layer over Antarctica, but what is less well known is that occasionally, the protective ozone in the stratosphere over the Arctic is destroyed as well, thinning the ozone layer there.

Responses to climate change: Carefully weigh up the consequences for water bodies
Responses to climate change: Carefully weigh up the consequences for water bodies
It is no secret that climate change has a serious impact on the quality and ecology of aquatic environments. Researchers at Eawag have revealed that human responses to climate change are just as impactful on our water systems - for example, in the areas of agriculture and hydropower. When thermometers in California recorded scorching temperatures in the summer of 2000, even the salmon in Klamath River felt the effects.

Drought-Exposure History Improves Recovery of Grassland Communities from Subsequent Drought
Drought-Exposure History Improves Recovery of Grassland Communities from Subsequent Drought
When a plant community is exposed to drought, the different species undergo evolutionary changes. An international study with UZH participation now shows that this leads to improved resilience to future drought stress over time. The exposure to drought during previous generations in the field increases complementarity between offspring of different grassland species and thus makes them more resilient to subsequent drought.

Water treatment plants would be ready for the removal of nanoplastics
The biologically active, slow-flow sand filters of lake water treatment would remove nanoplastics from the raw water very efficiently. This was shown both in the laboratory and in larger, realistic tests and modelling. It's a hot topic, at least on social media: tiny plastic particles allegedly end up not only in oceans and lakes, but also in drinking water - and, yes, even in bottled mineral water.
