Welcome to the PSI Newsroom! Scroll through the latest news from our research and our worldwide unique large research facilities.
News & Stories from PSI
Wildfire in a wood-burning stove
Researchers at PSI have demonstrated in a laboratory experiment how, after wildfires, nitrate in the atmosphere is converted into nitrogen oxides, which are harmful to health and the climate.
Making life cycle assessment more accurate
Life cycle assessments are an important basis for political decisions. However, they are often based on incomplete data. A PSI study shows how hybrid methods can deliver more accurate results.
Safe and clean: new concepts for nuclear energy
Reactors that remain safe without pumps or electricity. Molten salt instead of water as a coolant. And technological breakthroughs for fusion. At PSI, the materials and models needed for such reactors are being created – thanks to facilities that exist nowhere else in the world.
Pollen research as a collaborative project
The citizen science project Pollen Watch brings together people from all over Switzerland – to track pollen and the climate.
Soon at PSI
