South Korean scientists just talked cancer cells out of being cancer. Nothing got killed. The cells were flipped back. A KAIST team led by Professor Kwang-Hyun Cho built a digital twin of the gene network that guides normal colon cells as they mature. Simulations pointed them to the master switches. When they shut those off in colon cancer cells, the cells reverted to a normal-like state, and lab experiments and animal studies backed it up. That’s huge. Chemo and radiation wreck healthy tissue along with the tumor, and the cancer often comes back resistant anyway. Cho calls it reversible cancer therapy. You repair the cell and leave it alive.
