Researchers have achieved a major scientific milestone by using advanced CRISPR prime-editing technology directly inside the human body. The high-precision gene-editing approach is being tested in a clinical trial targeting a rare genetic disease affecting the liver and nervous system. Scientists say the breakthrough could open a new era of medicine by allowing genetic disorders to be corrected without removing cells from the patient. The development is widely viewed as one of the most significant advances in biotechnology and personalized medicine this year.
