Der Schweiz fehlen bald die Radiochemie-Fachleute
Für aktuelle und zukünftige Herausforderungen wie den Rückbau von Kernkraftwerken benötigt die Schweiz Fachwissen zur Erforschung und Anwendung radioaktiver Stoffe. Mittelfristig zeichnet sich jedoch ein Mangel an Expertinnen und Experten ab. Gemeinsam mit verschiedenen Organisationen aus der Wissenschaft hat die Akademie der Naturwissenschaften Schweiz das Weissbuch Radiochemie Schweiz erarbeitet. Dieses zeigt Massnahmen zur Sicherung und Weiterentwicklung des erforderlichen Fachwissens auf. Mit der Schaffung einer neuen Professur haben die ETH Zürich und das Paul-Scherrer-Institut bereits einen wichtigen ersten Schritt gemacht.

Swiss precision in space
Switzerland does not launch any large rockets of its own, but it is involved in research missions throughout the solar system. Universities develop scientific instruments, companies supply high-precision technology, and a growing number of start-ups are seeking to develop new business opportunities from this.Swiss Young Academy SYA

More Swiss research in space: Florian Kehl on the development of space missions at ETH Zurich
Four telescopes that must maintain a stable focus on extremely faint galaxies for an exceptionally long time, and detectors that remain at a constant temperature of around –130 degrees Celsius throughout: the ARRAKIHS space telescope has been built to the very limits of what is technically possible. In June 2026, the European Space Agency (ESA) gave the go-ahead for the mission – with a Swiss contribution for which Florian Kehl was responsible until the end of 2025. To ensure that such contributions do not remain isolated cases, in addition to high-quality research, we need structures, streamlined processes and people who can get entire missions off the ground. This is precisely what Kehl is working on today as Director of Space Research Initiatives at ETH Zurich | Space. In an interview with SATW, he explains what makes ARRAKIHS so technically challenging, just how competitive Switzerland really is when it comes to securing leadership roles in European missions, and why, in his view, the search for extraterrestrial life might be on the verge of yielding an answer.
