Fundamental science from Japanese universities and national research institutes.
Waseda University, JAXA, the University of Tokyo, and Keio University have completed Japan's first Mach 5 combustion test using a hypersonic experimental aircraft. How does Japan's passenger-focused strategy compare with the US (Hermeus, Lockheed) and a militarily advanced China?
Researchers at Utsunomiya University have provided the world's first direct proof that ceramide deficiency in the skin causes atopic dermatitis. Using transgenic mice, they demonstrated the full disease cascade from barrier breakdown to allergic inflammation — opening doors for ceramide-based therapies and enzyme-targeting treatments for the 200+ million people affected worldwide.
Microplastic pollution isn't limited to oceans — it's now raining down on forests too. A TU Darmstadt study first proved that airborne plastics settle on tree canopies and accumulate in forest soil. With 67% of Japan covered in forests, the implications are enormous. Japanese researchers have also pioneered breakthroughs in understanding how trees trap airborne microplastics.
Kyoto University Professor Emeritus Hiroki Kamata warns Mount Fuji is in eruption standby mode, with high risk of being triggered by the Nankai Trough megaquake. NHK Special dramatizes Tokyo blackout scenario from volcanic ash, while Sakurajima continues active eruptions
Osaka Metropolitan University researchers discovered that butterflies raised on invasive plants develop altered wing coloration, making them less attractive to potential mates. The study reveals how changes in larval diet affect UV reflection patterns and reproductive success.
RIKEN and Osaka University have launched cloud access to Ei-II, a domestically developed 144-qubit superconducting quantum computer. Doubling the previous 64-qubit Ei, the 28x28mm chip enables quantum calculations beyond classical simulation. We compare it with IBM and Google systems and examine Japan's quantum roadmap.
Japanese researchers cloned mice from a single donor for 20 years, producing over 1,200 animals across 58 generations. After the 27th generation, lethal mutations accumulated until all 58th-generation clones died within days of birth — the first proof that mammal cloning has a hard biological limit.
University of Tokyo's MEVIUS2 is a Spot-sized open-source quadruped robot built from sheet metal and e-commerce parts. With full hardware and software on GitHub, LiDAR and HDR camera perception, and reinforcement learning locomotion, it aims to democratize advanced robotics, at a fraction of Spot's $74,500 price tag.
AIST developed a voltage-induced static magnetization switching method using artificial antiferromagnets, enabling stable writing across a wide pulse-width range for voltage-driven MRAM. Published in Nature Materials, this breakthrough could lead to ultra-low-power memory for AI and IoT devices.
A Japanese research team has achieved what was considered impossible for over a century: creating a transparent, millimeter-sized bulk piece of amorphous alumina. With a dielectric constant of 11.3, surpassing sapphire, and a novel pentahedral pyramid structure, this JACS-published breakthrough could reshape semiconductor and capacitor materials.
Researchers at Kobe University have achieved the world's first inkjet printing using structural color nanoparticle ink — no dyes, no pigments, just silicon nanoparticles that produce color through light resonance. The result: vivid prints that never fade, with applications from eco-friendly packaging to anti-counterfeit security.
