Recent discussions highlight the discovery of a new organ, the interstitium, which has sparked interest in its implications for human anatomy and health. This discovery, based on a paper published in March 2018, proposes a reevaluation of the human interstitium as a significant, fluid-filled space within and between tissues. The conversation touches on the evolving definitions of what constitutes an organ, drawing parallels to debates in astronomy, such as the classification of Pluto. Participants express curiosity about the potential connections between the interstitium and the lymphatic system, particularly regarding cancer and other diseases. Skepticism exists about the validity of the findings, with some questioning the methods used in the research and the conclusions drawn. The discussion emphasizes the importance of scientific rigor and the evolving nature of scientific understanding, suggesting that while new discoveries may challenge existing paradigms, they must be supported by robust evidence.
