Organic molecules such as amino acids that make up life have ``enantiomers'' that form pairs like left and right hands. Life on Earth uses only one or the other, and the mechanism by which this ``bias'' is created has been a mystery for many years.
Why does life on Earth use only one of the two types of molecules with three-dimensional structures, left and right? The discovery by Professor Emeritus Kenzo Soai (76) of the Tokyo University of Science, which provided a clue to this mystery and was awarded the Nobel Prize in Chemistry, has also become the starting point for the exploration of the origin and traces of life on asteroids, such as the Hayabusa 2 probe.

Organic molecules such as amino acids that make up life have ``enantiomers'' that form pairs like left and right hands. Life on Earth uses only one or the other, and the mechanism by which this ``bias'' is created has been a mystery for many years. Soai discovered an ``asymmetric autocatalytic reaction'' in which a very small difference between the left and right sides multiplies and becomes biased towards one side. It was shown that this kind of reaction can occur in nature, and it came to be called the ``Soai reaction''.
So where did it happen? Yoshiki Takano, head of the Materials and Earth Science Research Division at the Japan Agency for Marine-Earth Science and Technology, which studies amino acids detected in the sand of Ryugu, the asteroid brought back by Hayabusa2, says, ``We hypothesized that the answer might lie in Ryugu, so we took on the mission.''
However, no bias was found in samples brought back from Ryugu or the asteroid Bennu by the US spacecraft. Takano points out, ``The current situation is that its origins are still shrouded in mystery.'' Japan's Mars satellite exploration mission, MMX, which is scheduled to be launched this month, is also scheduled to bring back samples, and he hopes that ``we will be able to find out the answer to what happens to the left and right in the Martian sphere near the Earth.''
Takano said, ``Life on Earth exists because a reaction occurred somewhere in the natural world.Our role is to search for that location.''

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.

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.

Professor Emeritus Kenzo Go of the Tokyo University of Science, who was selected to receive the Nobel Prize in Chemistry, held a press conference in Tokyo and expressed his joy and gratitude to his collaborators. He said he received the news of the award while shopping.

Professor Emeritus Kenzo Go of Tokyo University of Science, who was selected to receive the Nobel Prize in Chemistry, spoke of his joy at receiving the award. The award was in recognition of his research into the catalytic reaction he discovered in 1995, and he expressed his respect for co-recipient Henri Kagan and his desire for future research.
