Abstract: A decade ago, we published a paper describing how reductive homologation of hydrogen cyanide and derivatives thereof can give rise to nucleotides alongside lipid and amino acid precursors. The reaction network relied upon reduction of hydrogen...

Abstract Ever since the universality of DNA and the genetic code were discovered between 1953 and 1965, molecular biologists and chemists have explored the steps required to evolve life as know it from simple chemistry. As the first genome sequences from...

Abstract: Ribosomal peptide synthesis (RPS) is orchestrated through the aminoacylation of RNAs by aminoacyl-tRNA synthetase enzymes that are produced by RPS. This causal paradox, which was established prior to the evolution of life’s last universal common...

"Precision Cavity-Enhanced Spectroscopy for Astrochemistry and Atmospheric Science" Light beaming to us across space encodes features arising from the absorption and emission of photons by a menagerie of interstellar molecules. Identification of these...

Abstract: Using high-resolution magnetometry, we show that mobile-lid plate tectonics on Earth had initiated by at least 3.5 Ga and that the Martian dynamo persisted longer than expected. These geophysical conditions likely enhanced the early habitability...
