On September 20 1313, the Academy of Sciences of the Royal Swedish Academy announced that it would award the 20 14 Emmenov Prize to Professor Tsinghua University in recognition of his pioneering contribution in the field of apoptosis research by using X-ray crystallography. Old cells are constantly dying and new cells are constantly being generated, which is a necessary condition for the survival of biological organs. Shi made a series of studies on protein by crystallography, which not only drew the three-dimensional structure of protein, but also got a deep understanding of the specific principle of apoptosis. The cause of cancer has always been one of the goals of scientists all over the world. The new discovery of stone in many biological fields provides important clues for developing new anti-cancer and anti-Alzheimer's drugs.
