A single fusion reactor needs about 10,000 km of high-temperature superconductor tape, and five years ago almost no one could make that much. Now four Italian physicists at startup Suprema are building Europe's largest tape plant to break in. But the companies that already dominate this wire are mostly Japanese: two of the four global fusion-grade producers are based in Japan. Inside the race over the thin ribbon fusion runs on.
Terahertz promises jaw-dropping 6G speeds, yet a passing body can kill the link. NICT just demonstrated the world's first system that auto-switches between millimeter and terahertz waves. The real breakthrough isn't a speed record but knowing when to give up on speed.
In 2004, virologist Yoshihiro Kawaoka titled a dialogue A Pandemic Will Definitely Come. COVID proved him right 16 years later, and the bird flu he truly feared, H5N1, is now spreading in cattle and people. A 20-year reckoning.
Researchers from Tokyo University of Science and Yokohama National University built a photocurable resin that hardens with light and melts back to liquid with heat. Using anthracene photodimerization, it recycles 10-plus times with no initiators or additives.
Akita Prefecture has adopted environmental DNA surveys that estimate whether bears passed within 1km upstream in the past 24 hours from a single glass of river water. We explain how it works, its limits, and how it compares with grizzly-detection efforts abroad.
Kagawa, Japan's self-styled udon prefecture, throws away thousands of tons of noodles a year. Two teams found wildly different uses for the waste: a small factory that turns it into electricity, and a professor who turns it into surprisingly tough paper grown by microbes, now made at a welfare facility for Marugame's traditional fans.
Japan's new cargo ship HTV-X1 reentered the atmosphere on the night of May 26, 2026, completing a roughly seven-month mission (JAXA announced it the next day). In its final two and a half months it gathered on-orbit data on next-gen space solar cells, including a domestic perovskite made by Ricoh, and received a radio signal from the ground. Here's why perovskite in space is a different story from perovskite on rooftops.
Honda's full-scale eVTOL demonstrator, designated F1, completed its first flight in the US, hovering for about 90 seconds. Instead of going all-electric, Honda chose a gas-turbine hybrid built for 400km-plus intercity range. Here's the contrarian bet, and the F1 and HondaJet technology behind it.
How does the brain run on intuition when the evidence is murky, and how does it know when to stop trusting that hunch? RIKEN researchers traced the circuit that stores recent sensory experience and the tiny brain region that acts as a mismatch detector to rewrite it. The same wiring appeared in an AI model, too.
University of Tokyo scientists find that heat lingers for seconds inside living cells instead of escaping instantly. How non-diffusive heat dissipation settles the decade-old 10^5 gap problem and what it means for temperature signaling and disease research.
A University of Tokyo and RIKEN team has switched a magnet in just 40 picoseconds with almost no heat, using the antiferromagnet Mn3Sn. Published in Science, the result shatters the nanosecond speed limit that has held back chips for years. Here is why the wall stood, and how it fell.
