26 March 2024, Baden-Württemberg, Stuttgart: Petra Olschowski (Alliance 90/The Greens), Minister of Science of Baden-Württemberg, looks at tissue sections of a colon tumor on a slide in a laboratory at the University of Stuttgart. According to the Baden-Württemberg Ministry of Science, the number of animal experiments has been further reduced in recent years, not least thanks to the success of alternative research. The so-called 3R network, which aims to avoid, reduce or improve animal experiments, has played a major role in this reduction Photo: Marijan Murat/dpa (KEYSTONE/DPA/Marijan Murat)
