Our third paper on the chemical origins of life is published in Nature. We show that ferrous iron promotes a one-pot reaction network that resembles the Krebs cycle and amino acid synthesis, starting from just pyruvate and glyoxylate. These enzyme-free reactions could have been a precursor to biological metabolism. Congrats to Kamila and Sreejith! Free read-only version here. Paywall version here.

Kamila and Elodie’s invited account of our recent work on non-enzymatic metabolic pathways has been published in Bioorganic & Medicinal Letters. The special issue is in honor of the 2019 Tetrahedron Young Investigator Award to Dr. Raphaël Rodriguez.
Elodie’s collaboration with Dr. Samir Mameri (IUT Robert Schuman) and Profs. Ruhlmann (Strasbourg) and Schmitt (Dublin) on the properties of Mn clusters has been published in Dalton Transactions. Congrats, Elodie!
The second paper from our collaboration with the Ebbesen group describing how running a reaction between two appropriately-spaced mirrors can change its selectivity has appeared in Science. Congrats to Lucas from our lab and to all who participated from the Ebbesen group!
Ed, Jing and Vuk’s paper in Chemical Science shows that hexafluoroisopropanol solvent enables simple monosubstituted cyclopropanes to undergo ring-opening hydroarylation – no donor-acceptor motif required. A good chunk of this work came from Jing’s M2 internship in our group. Special thanks to the Rowley group from Memorial University in Canada for the DFT calculations. Congrats to all!
Our second paper on the chemical origins of life is published in Nature Ecology & Evolution. We show that metallic iron powder fixes carbon dioxide as acetate and pyruvate much like the Acetyl CoA pathway, an ancient biological pathway used by microbes to build themselves. It represents a rare “chemistry-up” experiment that connects with the current “biology-down” understanding of early life. Congrats to Sreejith, Kamila and Paul! Free read-only version here.

Our paper on the chemical origins of life is published in Nature Ecology & Evolution. We show that more than half of the reverse Krebs cycle can occur without enzymes. Congrats to Kamila, Sreejith, Elodie, Lucas and Guang for an amazing team effort! A free link to the paper is here. The journal’s paywall version is here.
