Mistletoe‐ and Mussel‐Inspired Fabrication of Hierarchically Structured Protein‐Cellulose Scaffolds From Biomolecular Condensates

Advanced Materials, Volume 38, Issue 13, 3 March 2026.
Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...

Avenues for emergent ecologies

, 2013
In this work, we present some fascinating behaviour emerging from a simple synthetic chemistry model. The results of Ono and Ikegami (2001) demonstrated the spontaneous formation of primitive, self-reproducing cells from a random homogeneous mixture of ...

Conjecture and hypothesis: The importance of reality checks

Beilstein Journal of Organic Chemistry, 2017
In origins of life research, it is important to understand the difference between conjecture and hypothesis. This commentary explores the difference and recommends alternative hypotheses as a way to advance our understanding of how life can begin on the ...

Coupled Phases and Combinatorial Selection in Fluctuating Hydrothermal Pools: A Scenario to Guide Experimental Approaches to the Origin of Cellular Life

Life, 2015
Hydrothermal fields on the prebiotic Earth are candidate environments for biogenesis. We propose a model in which molecular systems driven by cycles of hydration and dehydration in such sites undergo chemical evolution in dehydrated films on mineral ...

Liquid DNA Coacervates form Porous Capsular Hydrogels via Viscoelastic Phase Separation on Microdroplet Interface

Advanced Materials Interfaces
Liquid–liquid phase separation (LLPS) droplets of biopolymers are known as functional microdroplets in living cells and have recently been used to construct protocells and artificial cells.

Compartmentalization and Cell Division through Molecular Discreteness and Crowding in a Catalytic Reaction Network

Life, 2014
Explanation of the emergence of primitive cellular structures from a set of chemical reactions is necessary to unveil the origin of life and to experimentally synthesize protocells.

Toward homochiral protocells in noncatalytic peptide systems

, 2009
The activation-polymerization-epimerization-depolymerization (APED) model of Plasson et al. has recently been proposed as a mechanism for the evolution of homochirality on prebiotic Earth.

Population Dynamics of Autocatalytic Sets in a Compartmentalized Spatial World

Life, 2018
Autocatalytic sets are self-sustaining and collectively catalytic chemical reaction networks which are believed to have played an important role in the origin of life.

From inanimate matter to living systems [PDF]

Since the early part of this century, the Genesis account of the origin and evolution of life has been explained as an extrapolation of astronomical and geochemical processes.

Evolution and self-assembly of protocells [PDF]

The International Journal of Biochemistry & Cell Biology, 2009
Cells define the minimal building blocks of life. How cellular life emerged and evolved implies to cross the boundary between living and nonliving matter. Here we explore this problem by presenting several relevant components of the whole picture involving chemistry, physics and natural selection.
