Visualize how radical species can affect entire chemical reaction networks.
Radicals are chemical species with unpaired outer valence electrons, and they have been intensively studied in disparate fields such as nuclear engineering, cosmochemistry and atmospheric modeling. Radicals can have extreme redox potentials and readily react with non-radical species to quickly diversify a chemical system. For these and other reasons, radicals play a variety of explicit and implicit roles in different origins of life scenarios. REPO was founded to bring together investigators from all over the world, so that we may draw upon decades of perspectives, data, and hands-on experiences with radical chemistry experiment designs.
The sun never sets on REPO! We are an international organization, and we are committed to increasing membership on every continent. Here we are by the numbers:
We invite all who are interested in learning more about radical chemistry to join REPO. Fill out the contact form to begin receiving regular newsletters. Your contact information will not be shared with others, and you will receive no solicitations from us. Our newsletters will only include:
- Summaries of recently published findings
- Overviews of new analytical or experimental techniques
- Research activities of our members
- Upcoming meetings or gatherings
- Highlights of past papers that shape research today
- Radical chemistry in the news
Please also use the contact form if you have specific questions that you think the members of REPO can answer about radical chemistry and the origins of life, or if you wish to contribute in an acknowledged leadership capacity to REPO. Our communications team will respond as quickly as possible to all inquiries.
The origins of life is a challenging but important scientific, philosophical, historical and cultural problem. Part of this difficulty lies in the paucity of direct evidence of life's emergence. REPO is committed to advancing the fields of prebiotic chemistry and radical chemistry by articulating and investigating hypotheses that are specific, testable and experimentally tractable.
For this reason, we regularly update hypotheses that connect radical chemistry to the origins of life and openly publish them here. We do this to encourage collaborative experiment design and cross-disciplinary communication. We also do this to emphasize how prebiotic chemical systems powered by radicals may be fundamentally different compared to chemical systems commonly invoked for prebiotic scenarios, such as those driven by redox gradients, pH differences, mineral catalysis or thermal potentials. Our objective is not to exclude or minimize these phenomena, or the decades of knowledge behind them, but to critically assess whether radicals more readily afford unique, systemic behaviors.
