Summary
Researchers developed "tanglecycles," self-reproducing metabolic systems from molecular automata. These acellular beings exhibit life-like properties such as self-reproduction and selection, offering a new prebiotic perspective on self-organization.
Area of Science:
- Artificial biochemistry
- Systems chemistry
- Origin of life studies
Background:
- Previous work proposed a molecular automaton to model the "molecular logic of the living state."
- This automaton comprises interacting informants and transformers.
Purpose of the Study:
- To demonstrate that tangled molecular hierarchies can form general hypercycles called tanglecycles.
- To investigate the properties of these tanglecycles as self-reproducing autocatalytic metabolisms.
Main Methods:
- Phenomenological study of tanglecycles derived from molecular automata.
- Analysis of information conservation within dynamical loops.
Main Results:
- Tanglecycles emerge from tangled molecular hierarchies.
- These systems function as self-reproducing autocatalytic metabolisms, termed "acellular beings."
- Emergent properties include self-reproduction, selection, and chaos.
Conclusions:
- Tanglecycles represent a novel form of self-organization with life-like characteristics.
- This approach offers a new perspective on the self-organization of matter from a prebiotic viewpoint.
- The study contributes to the understanding of autocatalytic networks and the origins of life.

01:23Characteristics of Life
Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...
02:55Synthetic Biology
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

01:16Non-equilibrium in the Cell
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...
01:29Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.

01:28Automatic Processing and Automatic Social Behavior
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...
01:24Origin of Cellular Life
The origin of life on Earth is a complex and enigmatic event rooted in ancient biochemical processes and geological conditions. Experimental evidence supports the hypothesis that life began with the spontaneous formation of organic molecules such as RNA nucleotides, amino acids, and lipids under early Earth conditions. Factors like volcanic activity, intense UV radiation, and a reducing atmosphere without free oxygen likely facilitated these reactions. Hydrothermal vents on the ocean floor are...
