Researchers report that microdroplets formed by the polymerization of drying α-hydroxy acids, present at the time of the origin of life on Earth, can act as compartments for chemical reactions and compounds, including genetic material; the results suggest that such microdroplets without enclosing membranes may have provided the combinatorial chemical heterogeneity necessary for living systems to develop, according to the authors.
