Nano-DSF glass capillaries filled with different brines. Crystallisation processes can be observed at the extremities of the capillaries. The red arrow indicates extensive crystallisation at the extremity of the capillaries containing the M1 brine. However, crystallisation was not limited to the M1 brine but to all of them. It could be observed both at the extremities and within the capillaries. -- Science Reports via PubMed

Tracing The Origin Of Earth Life’s Genetic Code To Early Protein Structures

Archaeal proteomes were systematically scanned to identify EPs with potential antimicrobial activity. Circular bars denote the log10-transformed average active (red) and inactive (blue) EPs discovered by APEX. A peptide was classified as active if its predicted mean MIC against tested bacterial strains was ≤100 μmol l−1. The values were normalized by the number of proteins per organism scanned. Archaea with peptides that were synthesized are indicated by a light red square, and those experimentally validated as active are highlighted with a dark red square. -- Nature Microbiology
