[2025 河北部分学校期中联考]The world was astonished when half of the Nobel Prize in Chemistry went to US scientist David Baker for "computational protein design" and the other half to Demis Hassabis and John M. Jumper in the UK for "protein structure prediction".
There is no doubt that they have made amazing breakthroughs. The Nobel Prize committee remarked that "they cracked the code for proteins' amazing structures". What attracted global attention was the fact that both Hassabis and Jumper come from DeepMind, which specializes in artificial intelligence, and they created an AI model that fundamentally changes the way to study a protein's structure.
It's notable that the AI model Hassabis and Jumper developed is central to understanding the structures of proteins, in which amino acids (氨基酸) are linked together in long chains and then fold in a manner that plays a decisive role in its functioning. Since the 1970s, researchers have been trying to predict protein structures from their amino acid sequences (序列) so as to gain a deeper understanding of their functions, for which they even launched Critical Assessment of Structure Prediction, which conducts community experiments in this regard.
For a long time the accuracy rate of predictions had been just about 40 percent, far below the required 90 percent. It was not until Hassabis and Jumper developed the AI model AlphaFold that the rate reached 60 percent, which has since got better with AlphaFold 2.
By understanding the three - dimensional structure of a protein, scientists can infer its role and how it interacts with other molecules (分子), which helps study diseases and develop new drugs. Besides, predicting protein structures helps in better comprehending the origins of life, which is linked to the Nobel Prize in Physiology that went to research into mRNA.
All these date back to Hassabis and Jumper's AlphaFold model developed decades ago. Clearly, AI has helped mankind by making endless computation a cakewalk, in the process quickening studies of the protein structures. The scientists who developed it deserve the prize as more scientists will be encouraged to study it.
