A spatial model of autocatalytic reactions
Biological cells with all of their surface structure and complex interior stripped away are essentially vesicles - membranes composed of lipid bilayers which form closed sacs.

Thermostability of model protocell membranes [PDF]
The earliest cells may have consisted of a self-replicating genetic polymer encapsulated within a self-replicating membrane vesicle. Here, we show that vesicles composed of simple single-chain amphiphiles such as fatty acids, fatty alcohols, and fatty-acid glycerol esters are extremely thermostable and retain internal RNA and DNA oligonucleotides at ...

We demonstrate new strategies to induce motility of vesicle‐based prototissue fibers by generating oxygen bubbles under an enzymatic reaction. The prototissue fibers exhibited flotation due to the buoyancy of oxygen bubbles and magnetotaxis due to the paramagnetic property of oxygen.

Sustainable Growth and Synchronization in Protocell Models
The growth of a population of protocells requires that the two key processes of replication of the protogenetic material and reproduction of the whole protocell take place at the same rate.

Growth states of catalytic reaction networks exhibiting energy metabolism
All cells derive nutrition by absorbing some chemical and energy resources from the environment; these resources are used by the cells to reproduce the chemicals within them, which in turn leads to an increase in their volume. In this study, we introduce

Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

Lipid vesicles chaperone an encapsulated RNA aptamer. [PDF]
The organization of molecules into cells is believed to have been critical for the emergence of living systems. Early protocells likely consisted of RNA functioning inside vesicles made of simple lipids.

A new strategy for temporal control over simple and complex coacervates is described here. The urea‐urease reaction results in the timed formation and/or destruction of complex coacervates after controllable delays. This strategy is easily adaptable to different time scales and polyelectrolyte pairs.
