This week we have 3 preprints and 17 new papers on the origin of life. I don’t usually include exoplanet papers but did include one this week for a particularly interesting candidate (Faria paper). Enjoy!

This week we have 8 preprints and 22 new papers on the origin of life, from astrobiology, biochemistry, biology and planetary science. Enjoy!

This week, there were 15 articles published on the origin of life in astrobiology, biochemistry, biophysics and microbiology. In astrobiology, we have papers on simulated habitability (Claudi), water detection on exoplanets with JWST (Ding), detection of basal reflections on Mars (Mattei) and a proposal for the DRAKE spectroscopy survey of M-dwarfs (Sarkar). In biochemistry, we have papers on polymerization of glycine and alanine (Baú), flocculation and dehydration (Cohen), DNA uptake (Kapteijn), cysteine encoding systems (Mukai), heredity in protocells (Palmeira), synthesis of aminoacyl-RNA (Roberts), storage of biochemical information (Schreiber) and CO$_2$ adsorption in FeS surfaces (Živković). In biophysics, we have a single article on non-equilibrium thermodynamics of the origin of life. Finally, in microbiology, we have a paper on Txikispora philomaios and the origin of multicellularity (Urrutia) and another one on microbial survival in extreme ecosystems (Wang). Enjoy!

This week, 16 articles were published on the ool in astrobiology, biochemistry, biophysics and planetary science. In astrobiology, we have papers on biosignatures (Goodwin), organic molecules in the ISM (Guelin), Raman spectroscopy on CanMars (Lalla), the impact of photochemical runaway on biosignatures (Ranjan), ocean stability on ancient Mars, the panspermia hypothesis (Sithamparam) and an in situ microbial detection system (Touchette). In biochemistry we have papers on prebiotic organocatalysts (Closs), lipid membranes and RNA interactions (Czerniak), host-parasite molecular replication networks (Kamiura), viroids (Lee) and simulations of a minimal cell (Thornburg). In biophysics, we have a paper on self-organized emergence of behavior (Fleig) and in planetary science. Finally, in planetary science we have papers on impacts on early Earth (Citron), $O_2$ increase in the Archean (Leong) and an Earth-system biogeochemical model (Cole). Enjoy!

Another big week in ool research with 11 papers published since last week. In astrobiology, Kraus presents a model of high-pressure melting curve for the iron – influencing dynamo-generated magnetospheres, an important component of habitability, Nixon presents the AURA-3D atmospheric retrieval framework for exoplanet transmission spectra, Salter characterizes the mass spectrometric fingerprints of microbial life, Sforna presents the first in-situ evidence of chlorophyll remnants in a billion-year-old multicellular algal microfossil and Steele analyzed the nanoscale mineralogy of the Mars meteorite ALH 84001. In biochemistry, Bromberg explored the patterns of evolution of enzymes responsible for biological redox reactions, Cowan discusses microbial trace gas chemotrophy as a metabolic strategy to support energy and carbon acquisition for microbial survival, Lu analyzes change in cell morphology of Escherichia coli exposed to a resource utilization regime mimicking a primordial environment, Márquez-Zacarías analyzes the evolution of cellular differentiation through the use of Boolean networks, and Steller analyzes how how dehydration/rehydration events can remodel dense lipid aggregates into thin-walled vesicles capable of RNA encapsulation even at acidic pHs. Finally, in planetary science Leong investigates how decreasing extents of Archean serpentinization contributed to the rise of an oxidized atmosphere.

Big week in ool research: we have eight papers in astrobiology, biochemistry and planetary science. In astrobiology, Franz discusses the Breakthrough Listen Initiative – a technosignature search for TESS TOIs, Fujiya reports the radiometric age of a C-complex asteroid with implications on their occurrence, Pearce presents a chemical model of early Earth atmosphere and discusses the rain-out of HCN and its implications for the warm little ponds hypothesis, and Svensmark discusses supernovae frequency and distribution of organic matter. In biochemistry Pan reviews the relevance of viruses for ool scenarios and Heili reports experiments on cellular export of functional protein and RNA products. Finally, in planetary science Slotznick reexamines a transient pre-GEO oxygenation event and Cooke uses a three-dimensional chemistry-climate model to simulate changes in $O_3$ since the GOE, with implications for terrestrial habitability.
