Giant tortoises are naturally long-lived, and Jonathan lived to be 194 years old, more than twice the lifespan of his species. Previous research has shown that the decline in mitochondrial function in old age is associated with aging.
In order to unravel the mystery of the extremely long lifespan of Jonathan, the world's oldest male giant tortoise at 194 years old, DNA was collected and the entire genetic information (genome) was analyzed in detail, and it was discovered that a group of genes that maintain the function of mitochondria, the organelles that produce energy within cells, and repair damaged DNA are well regulated.
An international research team from the Charles Foundation and Vanderbilt University announced this in the American scientific journal Science Advances on the 7th.
Mitochondria are small organelles within a single cell that produce the energy substance adenosine triphosphate (ATP). Normally, mitochondrial function declines as we age, but a genome analysis of a Spanish woman who died in 2024 at the age of 117, the world's oldest person at the time, revealed that her mitochondria were working extremely well compared to her peers.
Cellular energy production is the basis of whole-body activities, and a decline in mitochondrial function appears to be behind the various chronic diseases that increase in the elderly. The research results are expected to help elucidate the detailed mechanism of aging and develop more effective countermeasures.
Jonathan is an Aldabra giant tortoise that lives in Aldabra Atoll in the Indian Ocean. The turtle has been kept in captivity since 1882 when it was presented to the governor of St. Helena, a British colony in the South Atlantic, and in 2022, at the age of 190, it was recognized by the Guinness Book of World Records as the oldest turtle. Giant tortoises are naturally long-lived, but they live more than twice as long as other species.

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.

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.

The Royal Swedish Academy of Sciences has announced that the 2026 Nobel Prize in Chemistry will be awarded to Professor Emeritus Kenzo Go of the Tokyo University of Science and Professor Emeritus Henri Kagan of the University of Paris-Saclay. Discoveries such as ``asymmetric autocatalytic reactions'' that produce only one enantiomer were praised.
