Science journalism, a unique form of science communication, faces grand challenges requiring innovation for its sustainability. This practice insight delves into a research-practice collaboration addressing the “WPK Innovation Fund for Science Journalism”, a pioneering support infrastructure for innovation in German science journalism. Our transformative accompanying research project aims to both support the fund's development as well as advance science journalism research. This report, co-authored by researchers and practitioners, showcases opportunities and challenges, drawing from the three forms of knowledge generated in the collaboration: systems, target, and transformation knowledge. Each of these forms sheds light on specific lessons learned in our project on how to conduct transformative journalism research.
