Chinese scientists have recently introduced a revolutionary technology that has proven effective in studying old biological samples. Although experts admit that old samples are more likely to suffer from chemical damage and breakage, the modern RNA mapping technology Stereo-seq V2 developed by Chinese researchers has opened new doors of possibilities. Thanks to this technology, it is hoped that one day it will be possible to study Einstein’s brain and trace the cellular basis of intelligence. It should be remembered that Einstein’s brain was divided into 240 sections after his death and preserved on microscope slides. In the past, studying such old samples has proven difficult, because their genetic structure weakens over time.
