Chiral chemistry is a field that studies phenomena in which only one enantiomer of a molecule exists. Although Pasteur discovered molecular chirality in his experiments with tartaric acid in 1848, it was not clear for many years why living organisms only produce one isomer.
Professor Emeritus Kenzo Go (76) of Tokyo University of Science, who was selected to win the Nobel Prize in Chemistry, has been working to solve the mystery of why the amino acids and sugars that make up living things are only one enantiomer. The ``discovery of asymmetric autocatalytic reactions,'' for which he was awarded the award, is part of this research, and this field is called ``chiral chemistry.'' At the press conference on the 7th, where the award was announced, Soai said that the invention began with experiments conducted by French chemist and bacteriologist Louis Pasteur in the mid-19th century.
When he visited the Pasteur Institute in Paris, he saw a small box containing crystal samples that Pasteur may have used in his research, and he was ``quietly moved.''
When reflected in a mirror, they look the same, like the right and left hands, but the property that they cannot be superimposed is called "chirality." In the first half of the 19th century, it was discovered that when light was passed through a crystal, the plane of vibration of the light wave could be clockwise or counterclockwise, and the reason for this was thought to be the difference in the crystal structure of the crystal.
This difference in "optical rotation" also exists in sucrose and the tartar that precipitates in wine. In 1848, Pasteur conducted an experiment to measure optical rotation in a solution of ammonium sodium tartrate and discovered that the difference was due to the chirality of the molecule itself. Afterwards, he worked on the research theme of ``Why do living organisms produce molecules of only one enantiomer?'' He investigated the effects of sunlight direction and magnetic fields, but was unable to find a solution.
Mr. Soai also tackled this ``time-honored theme'' and showed that it is possible to undergo an asymmetric autocatalytic reaction in which only one enantiomer molecule uses itself as a catalyst and continues to increase overwhelmingly. Self-replication is a characteristic of living things, and ``it becomes a very convenient system to last for a long time.''

Kenzo Soai, Professor Emeritus of Tokyo University of Science, who was selected to receive the Nobel Prize in Chemistry, gave an interview to Jiji Press and reflected on the research progress that led to the discovery of ``asymmetric autocatalytic reactions,'' which are related to the origin of life, and the influence of his mentor, the late Mitsuaki Mukaiyama.

Professor Emeritus Kenzo Soai (76) of Tokyo University of Science discovered ``asymmetric autocatalytic reactions'' and was awarded the Nobel Prize in Chemistry. This discovery will lead to elucidation of why life on Earth uses only left-handed molecules, and will serve as a starting point for research on the origin of life on asteroids and in the Martian sphere, including the Hayabusa2 exploration of Ryugu and the future MMX mission.

On the 8th, one day after the Nobel Prize in Chemistry was announced, Professor Emeritus Kenzo Go of Tokyo University of Science responded to an interview in Shiki City, Saitama Prefecture. While talking about his joy at receiving the award, he expressed his desire to continue his research.

The morning after receiving the Nobel Prize in Chemistry, Kenzo Go (76), professor emeritus at Tokyo University of Science, gave an interview to the press in Shiki City, Saitama Prefecture. Regarding how he felt about receiving the award, he said, ``It's still unclear,'' but he responded to congratulations from nearby residents and showed concern for the press.

Genomic analysis of Jonathan, the world's oldest giant tortoise at 194 years old, revealed that a group of genes involved in maintaining mitochondrial function and DNA repair are well regulated. An international team including the Carrel Foundation in the US published this in Science Advances. Expectations are high for elucidating the longevity mechanism.
