In laboratories at two South Korean universities, a small team of researchers has quietly closed the gap between artificial intelligence's promise and medicine's demand for precision. Their tool, OpenABE, corrects single miswritten letters in the genetic code with an efficiency 36 times greater than its AI-designed predecessors — not by abandoning human expertise, but by weaving it together with machine intelligence. The achievement matters because it transforms a class of molecular editors that were too imprecise for patients into instruments that may one day treat disorders once considered b
