Abstract
Prestellar cores are stellar mass high density structures embedded in molecular clouds which are thought to be the forerunners of protostars. I will give a brief overview of their properties and of the debate concerning their evolution. Recent ALMA observations show evidence for the presence of structures of around a thousand AU in diameter in a couple of these cores. I will discuss what one can say about the nature of these objects and whether they throw any light upon how these cores will evolve.
