SK hynix has begun sampling the world’s first 12-layer HBM4, a 36 GB stack delivering more than 2 TB per second. Demonstrated at Computex 2025, the memory targets Nvidia’s Rubin GPUs and could reshape AI hardware.

Japan is doubling down on solid oxide fuel cells, trading decades-old lab dreams for tangible gear that can heat homes and power skyscrapers. From a rubidium-doped ceramic that slashes operating temperatures to Mitsubishi Power’s 250-kW MEGAMIE hybrid humming beneath downtown Tokyo, the country is stitching together breakthroughs, subsidies and sheer persistence. If the pieces hold, Japan could soon export not just fuel cells but a blueprint for post-fossil resilience.

Japan’s manufacturing PMI edged into expansion territory for the first time in 13 months, signalling a tentative revival even as U.S. tariff threats cast a shadow.

Tokyo is humming again, the kind of low-key rumble that signals something big is on the way. From bio-fuelled flights and Edo-purple stadium lights to medal cases carved from fragrant Tama cedar, the city is racing to outshine its own Olympic legacy as the 2025 World Athletics Championships sprint into view.
