On the Terminology of Lipid Nanoparticles, Liposomes, and Vesicles
The terms “liposome,” “vesicle,” and “lipid nanoparticle” (LNP) should be defined clearly to avoid conceptual and practical errors. Structures and distinctions are introduced here for nonspecialists. Overly broad use of “LNP” to refer to any nanosized, lipid‐based assemblage is discouraged.

Abstract Several national space agencies and commercial entities are currently targeting the Moon's south polar region for human and robotic exploration. Of particular interest are materials excavated and ejected from the Moon's largest and oldest impact structure, the South Pole‐Aitken Basin (SPA), as these ancient materials are a window into the ...
