Hemifusomes were disovered this year. One of the organelles inside your cell that we didn't even know were there until now.
They think they are part of making new vesicles (transport devices).

A very new Wikipedia article about the Hemifusome! It was not yet scrutinised by stickling Wikipedians so it reads more like a scientific article than a Wikipedia article! Wow!
From https://en.wikipedia.org/wiki/Hemifusome:
Hemifusomes are intracellular organelles first described in 2025 by researchers at the National Institutes of Health and the University of Virginia School of Medicine.[1][2] Discovered using in situ cryo-electron tomography, hemifusomes are heterotypic vesicular complexes marked by a persistent hemifusion diaphragm and a characteristic 42-nanometer proteolipid nanodroplet (PND). These organelles account for up to 10% of vesicular structures at the cell periphery and often contain intraluminal vesicles, but they do not participate in conventional endocytic pathways. Hemifusomes are proposed to act as platforms for vesicle biogenesis via an ESCRT-independent mechanism for multivesicular body formation. Their shape has been likened to a snowman wearing a scarf.
