Compositional Diversity Of Minimal Coacervates In A Nucleic Acid-peptide World
The early co-evolution of RNA and peptides is at the core of the RNA-peptide world hypothesis. Recent studies suggest that nucleotides and amino acids could have formed and polymerised non-enzymatically […]

Coenzyme-Protein Interactions Since Early Life
Recent findings in protein evolution and peptide prebiotic plausibility have been setting the stage for reconsidering the role of peptides in the early stages of life’s origin.
![Coupled bilayer nanopore concept for physical guiding, tracking and sizing of single molecules a, Fabrication schematic including EBL, etching, 2D materials transfer and AC-STEM sculpting. SiN nanopores constitute a GURU platform. Pore thicknesses are tSiN and t2D, diameters are dSiN and d2D and the total thickness is tGURU. Device configurations are denoted as [N, M] for N SiN pores and M 2D pores. σSiN and σ2D denote surface charge densities of SiN and 2D pores, respectively. The interlayer separation, L, can be experimentally controlled by the duration of RIE. -- Nature](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/09/Tricorder-Tech-Novel-Coupled-Nanopore.png?resize=1200%2C719&ssl=1)

Structural Adaptability and Surface Activity of Peptides Derived from Tardigrade Proteins
Tardigrades are unique micro-organisms with a high tolerance to desiccation. The protection of their cells against desiccation involves tardigrade-specific proteins, which include the so-called cytoplasmic abundant heat soluble (CAHS) proteins.
