@frontierresearch.coDid ultraviolet light on the early Earth pick life's genetic letters? Under continuous UV, the canonical nucleobases and nucleosides spanned nearly the entire range of degradation rates measured. UV photostability alone may not explain the choice, the authors conclude.
@frontierresearch.coCould chemistry inherit before genes? In a model, two interacting autocatalytic networks in dividing compartments hold alternative stable states; rare compartments dominated by the unfavored network arise by chance at division and win when conditions change.

@chemistryunwrapped.bsky.socialWhat if a coin toss decided the handedness of life? 🪙🧤
This year’s Nobel Prize in Chemistry recognizes a remarkable idea: a tiny preference for one hand can be amplified until almost every molecule has the same handedness.

@hlouchova-lab.bsky.social(2/2) Arg and Lys promote condensation more readily than simpler cationic amino acids, highlighting how amino acid chemistry may have shaped early RNA–peptide organization.
