DOI: 10.1073/pnas.2400819121 A large team of chemists at Harvard University has found evidence suggesting that cloud-to-ground lightning strikes may have helped generate some of the building blocks needed for life on Earth to arise . In their paper published in the Proceedings of the National Academy of Sciences , the group describes how they set up an experiment in their lab meant to mimic the conditions on early Earth and then studied the results of chemical reactions that occurred as lightning strikes were simulated . Prior research has suggested that life may have gotten its start on Earth through ma...
