Prelude, Supra, Primera, Pajero: Japanese carmakers keep reviving retired nameplates. Four forces explain it, from trademark law and the EV-era heritage premium to a 1988 US import rule still moving prices in Japan.
PET scans of 37 patients whose hallucinations began after age 40 found tau, the protein behind Alzheimer's, in 64.9% of them against 14.9% of controls. They split into three near-equal groups.
AIST and Tokyo startup OptQC have switched on MoQuren, a photonic quantum computer that needs no refrigerator and no vacuum chamber. What it can do now, and how Japan's bet differs from the US and China.
A Japanese developer has built a full Sengoku strategy game that runs inside the Vim text editor. Set in 1560, it holds 41 provinces, 32 clans and 256 historical generals in one 2,371-line file.
Glassy radioactive particles called cesium balls were thought to stay in Fukushima's topsoil. A Kyoto University team found them inside 39 of 52 earthworms, and one 15.5 centimeters down.
Sensitive teeth affect roughly a third of adults in some surveys, and the usual fix is to seal the surface over. A Tokyo Dental College team has shown that 6-MSITC, a compound in Japanese wasabi, pushes dentin-building cells to lay down new tissue instead. It began with a question asked at a sushi counter in Kanda.
Rolls-Royce, IHI and Avio Aero say the GCAP engine demonstrator is close to final design approval after more than 100 component tests, with ground running next. Sixth-generation fighter engines are judged on electrical power and heat, not just thrust. What Japan brought, and why co-designing an engine breaks with the F-2 era.
The first commercial transplant of AMCHEPRY, the world's first approved iPS cell-derived medicine, is set for October in Kyoto. Why proving it takes 35 patients and six years, and why the US and EU have no equivalent product.
Japan's amended privacy law, passed on July 10, 2026, waives consent for acquiring and sharing personal data when the purpose is AI training or statistics. Medical and criminal records sit inside the exception. The design runs on the same logic as Japan's copyright carve-out, and that is what sets it apart from the EU and South Korea.
A terbium-doped AlGaN LED from the University of Osaka and Ritsumeikan University emits four colors from a single spot, with wavelengths that barely move as the current rises.
University of Toyama researchers crystallized an OLED's emitting layer inside a practical thin-film stack: up to 1,000 times the current density at 1 volt, and turn-on at 1.33 V.
