Air traffic is responsible for two to three percent of global carbon dioxide emissions. To meet the goals of the Paris Climate Agreement and make air travel climate-neutral by 2050, PSI is carrying out research into sustainable aviation fuel. This could make an important contribution to reducing the climate damage caused by aviation.

As part of the Ice Memory initiative, PSI researchers, with colleagues from the University of Fribourg and Ca’ Foscari University of Venice as well as the Institute of Polar Sciences of the Italian National Research Council (CNR), analysed ice cores drilled in 2018 and 2020 from the Corbassière glacier at Grand Combin in the canton of Valais. A comparison of the two sets of ice cores published in Nature Geoscience shows: Global warming has made at least this glacier unusable as a climate archive.

Future-oriented research requires facilities that are continually brought up to date. That’s why PSI is currently planning a significant upgrade to its proton accelerator with the project IMPACT. Physicist Daniela Kiselev is head of Accelerator Operation and Development at PSI. In addition, she is leading the project management team for IMPACT. In this interview, she talks about the smallest particles and the big plans for the renovation.

Blood cells reveal tumours in the body. Researchers at the Paul Scherrer Institute achieve an advance with the development of a test for early diagnosis of cancer.

Researchers at PSI and ETH Zurich have taken connective tissue cells that have been mechanically reprogrammed to resemble stem cells and transplanted them into damaged skin. In their laboratory experiment, they were able to show that this can promote wound healing.
