The first junior European Calcium Society meeting: calcium research across scales, Kingdoms and countries.

The first junior European Calcium Society online meeting, held October 20-21, 2020, aimed to promote junior researchers in the Ca community. The meeting included four scientific sessions, covering Ca research from molecular detail to whole organisms. Each session featured one invited speaker and three speakers selected based on submitted abstracts, with the overall aim of actively involving early-career researchers. Consequently, the meeting underlined the diversity of Ca physiology, by showcasing research across scales and Kingdoms, as presented by a correspondingly diverse speaker panel across career stages and countries. In this meeting report, we introduce the visions of the junior European Calcium Society board and summarize the meeting content.
