Fundamental science from Japanese universities and national research institutes.
A Japanese research team from Fukui, Tohoku, Chiba, and Tokyo universities has theoretically proposed a new method to detect Majorana particles using spin currents. Not an observation but a proposal, it opens a fresh window onto the quasiparticle behind topological quantum computing, the same goal Microsoft's Majorana 1 chip pursues.
Chiba Institute of Technology has achieved the world's first ground combustion test of thrust vector control (TVC) using a gas hybrid rocket. Part of the Hestia Project, which aims to launch small satellites via balloon-based "Rockoon" method, this breakthrough demonstrated successful thrust vectoring at 2.0 kN over 8 seconds — opening a new path for affordable space access.
A Japanese research team has developed OrthologTransformer, a generative AI that treats DNA like a language and redesigns genes to work better in new organisms. The result? Plastic-eating bacteria that are up to 10x more effective. Published in Nature Communications, this breakthrough could reshape how we fight plastic pollution worldwide.
Researchers at Kyoto and Hiroshima Universities created iPS cells from bonobos, chimpanzees, and gibbons, then achieved the world's first differentiation into limb bud mesoderm cells. Inside Japan's Whole-Zoo iPS Cell Project and its work on primate evolution, conservation, and zoo veterinary medicine.
Researchers at the University of Tokyo have built the CUBIC Organ/Body Atlas, a 3D map of every cell across all organs of mice and the entire body of newborn mice at single-cell resolution. Combining the CUBIC tissue-clearing method with a custom light-sheet microscope, the team pinpointed roughly 610 million cells in a newborn mouse. Published in Cell, the work points toward 3D pathology and whole-body drug evaluation.
Hitachi and the Institute of Science Tokyo extended coherence time roughly 280-fold and demonstrated 99.1% gate fidelity on natural silicon, the material standard semiconductor fabs already use, with no isotope purification. The result comes from a Concatenated Continuous Drive scheme combining continuous microwave irradiation with phase modulation. Unlike the superconducting route taken by IBM and Google, it builds on existing chipmaking, with cloud access targeted for fiscal 2027.
Kyoto Institute of Technology and Chuo University have developed a cooling-free infrared sensor using semiconductor carbon nanotubes (CNTs) with 11x greater sensitivity than conventional materials. Building on Japan's legacy in CNT research since their 1991 discovery at NEC, this breakthrough could transform autonomous driving, security screening, and medical imaging. Here's what it means and how Japan is reacting.
Osaka University spinoff Reimei has launched the world's first corporate clinical trial of a corneal epithelial cell sheet made from donor-derived iPS cells, with the first transplant performed on July 9, 2026. How the approach could ease the global corneal donor shortage, what the Lancet-published first-in-human data showed, and where Japan's regenerative medicine regulation stands against the US FDA.
Japan's Fugaku supercomputer achieved the world's first 100-meter resolution simulation of an entire typhoon lifecycle, from initial vortex to super typhoon over 4 days. The breakthrough revealed tiny vortices invisible to conventional 2km models that delay rapid intensification by a full day, offering critical insights for improving typhoon forecasting in an era of climate change.
Researchers at the University of Tokyo and the Tokyo Metropolitan Institute of Medical Science have developed a microneedle patch that delivers a COVID-19 vaccine simply by sticking it on the skin. A 3D-printed pillar-guided design lifts tip-loading efficiency to 16.5%, about 8.3 times conventional molding, and mice given the patch showed a 1.2-fold higher antibody response than conventional intradermal injection. How this mouse-stage technology aims at painless, room-temperature, self-applied vaccination.
Tohoku University and the University of Tokyo have developed DIVE, a multi-agent AI workflow that automatically reads and structures experimental data from scientific paper figures. By extracting over 30,000 data points from 4,000+ papers, the system proposed new hydrogen storage materials in just 2 minutes. Here's how this AI reading team is unlocking data trapped inside research charts.
