How life's building blocks took shape on early Earth: the limits of membraneless polyester protocell formation

A recent study found that polyester microdroplets can form in salt-rich environments, at low alpha-hydroxy acid concentrations, and in small reaction volumes. This expands on previous research and suggests that polyester protocells were likely more common on early Earth than previously thought.
