Nagasaki University researchers solved a 160-year taxonomic mystery dating back to Siebold's era, discovering that Japan's common red stingray actually comprises multiple species. The team formally described the new species Hemitrygon ariakensis, found primarily in the Ariake Sea, resolving confusion that began when specimens were first collected in the Edo period.

The Kakeya Conjecture, proposed by Japanese mathematician Sōichi Kakeya in 1917, has finally been proven in 3D space after 108 years. This historic proof by Hong Wang (NYU) and Joshua Zahl (UBC) is expected to have far-reaching applications in harmonic analysis, signal processing, and cryptography.

In 2025, French and British mathematicians proved a 40-year-old conjecture about the "spectral gap" of hyperbolic surfaces. Building on the late Maryam Mirzakhani's research, this discovery has potential applications in quantum chaos and efficient communication network design. We explain this complex mathematical world in accessible terms.

In 2025, a team of American mathematicians partially solved Hilbert's sixth problem, unresolved for 125 years. This groundbreaking achievement mathematically proves how microscopic particle motion gives rise to macroscopic fluid laws, shedding new light on the mystery of the "arrow of time."

Researchers at Japan's JAIST discovered that Ewingella americana bacteria from Japanese tree frog intestines completely eliminated colorectal cancer in mice with a single dose, achieving 100% complete response rate. This breakthrough significantly outperformed existing chemotherapy and immunotherapy treatments.

Kagoshima University's oncolytic virus "Surv.m-CRA-1" enters final clinical trials for primary malignant bone tumors. This revolutionary treatment can eliminate cancer stem cells resistant to conventional therapies, offering new hope for bone cancer patients who haven't seen a new drug in over 30 years.
