Japanese startup AirKamuy has developed a cardboard military drone priced at just $2,000—one-tenth the cost of conventional fixed-wing UAVs. The AirKamuy 150 assembles in 5 minutes, flies at 120 km/h for 2 hours, and is attracting attention from Japan's Ministry of Defense and Coast Guard. How is this disruptive innovation reshaping defense technology?

Mitsubishi Electric and Kyoto University have made a world-first discovery: graphite material that heals itself. HOPG's deformation resistance recovered from 41% to 97% within just 7 days. This breakthrough could revolutionize MEMS sensors in smartphones, wearables, and autonomous vehicles. A look at Japan's cutting-edge materials science.

Hiroshima University and Phenitec Semiconductor achieved the world's first SiC integrated circuit prototype production in a commercial fab. This revolutionary semiconductor technology operates at 500°C and under high radiation, enabling applications in extreme environments like Venus surface exploration and Fukushima nuclear decommissioning—expanding humanity's frontier through Japanese innovation.

University of Arizona researchers plan to use samples from asteroid Bennu, returned by NASA's OSIRIS-REx, to test the idea that consciousness existed before life. It is a minority view that mainstream science does not support. Here is what the hypothesis says, where panpsychism and astrobiology meet, and the criticism it faces.

Japan's perovskite solar cell market is projected to surge to nearly $26 billion globally by 2040, with key materials exceeding $9.5 billion. This flexible, lightweight technology invented in Japan could revolutionize renewable energy by enabling installation on walls, windows, and curved surfaces previously impossible for traditional solar panels.

UK aerospace startup Aeralis is developing a modular jet trainer that could succeed Japan's aging T-4 aircraft. With interchangeable components enabling basic to advanced training in one platform, and potential ties to GCAP cooperation, this innovative British design may transform pilot training worldwide.

An estimated 5 billion tons of gold are dissolved in Earth's oceans—20,000 times what humanity has ever mined. IHI's biosorption technology using algae has successfully extracted gold from hot springs and deep-sea vents. Could this breakthrough eventually set a ceiling on gold prices? We examine the science, economics, and challenges.

The JMSDF's oldest Aegis destroyers, the Kongō-class, are finally getting successors. As Japan weighs SPY-6 and SPY-7 radars, we examine what this means for ballistic missile defense and interoperability with the US Navy.

At CES 2026 Bosch demonstrated sensors that give robots a delicate sense of touch, combining its BMP585 pressure sensor with an inertial measurement unit so that even the brush of a feather is detected. A look at the frontier of humanoid touch and a MEMS sensor market projected to reach 19.2 billion dollars by 2030.
