Yamagata University is building Benibana Sat, a 1U CubeSat targeting launch by fiscal 2028. Named for the prefectural flower, the project is aimed less at the satellite than at keeping the firms and people who can build one inside the prefecture.

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. The proof, by Hong Wang (NYU) and Joshua Zahl (UBC), reshapes harmonic analysis and won Wang a 2026 Fields Medal.

Researchers at Japan's JAIST found that Ewingella americana, a bacterium from Japanese tree frog intestines, completely eliminated colorectal tumors in mice after a single dose, a 100% complete response rate that outperformed chemotherapy and immunotherapy in the same comparison. Here is what the preclinical study showed, and what it does not yet show.

A groundbreaking UK-Japan study reveals that playing Nintendo's Super Mario Bros. and Yoshi games can boost happiness and reduce burnout risk in young adults.
