Mysterious Obelisk Life Forms Discovered Inside Humans
Researchers have discovered thousands of previously unknown RNA structures, termed “obelisks,” residing within human-associated bacteria. These obelisks, smaller than typical viruses and lacking protein coats, are circular RNA molecules resembling viroids but found in diverse human body locations. Their function and impact on human health remain unclear, but their discovery challenges existing classifications of life and highlights the vast unexplored diversity of the human microbiome. Further research is needed to understand their evolutionary origins and potential influence on human biology.
