Researchers at the Institute of Science Tokyo have created a surface electrene: a crystal whose outermost layer is a sheet of loose electrons, with a work function lower than cesium. It survives open air because nitrogen caps it, then leaves as ammonia. Here is what it means for green fertilizer, and how it compares with the electrochemical routes pursued in China, Europe and the US.
NEC and New York University estimate that flood defenses on the Rockaway Peninsula could avoid up to $800 million in losses, pricing everything from transit disruption to residents' mental health in a bid to pull private money into climate adaptation.
Mitsubishi Gas Chemical has signed an MOU with Australia's Gold Hydrogen to study green methanol made from natural hydrogen in South Australia. Here is why a Tokyo chemical maker is going to the wellhead abroad, what the Toyota-ENEOS consortium is really buying, and how the global race for natural hydrogen is splitting along national lines.
Toray's new TSW-K/M/V RO membranes remove over 99.9% of salt and enough boron to run seawater desalination in a single pass, trimming energy, equipment and cost. Here's why it matters worldwide.
Kubota says its existing waste-melting furnaces destroyed three regulated PFAS at over 99.999 percent, with greenhouse-gas markers below detection. We check whether 'destroying forever chemicals' is really the breakthrough it sounds like.
JR East will phase out magnetic short-distance train tickets in spring 2027, replacing them with QR-code paper tickets. We break down the environmental and cost reasons, why almost no one will notice, and the small ritual that is quietly disappearing.
Aquaponics rarely pays as a standalone farm. So how does Aomori's closed-school project plan to make money? By monetizing the cafe, tours, education and welfare work around the tank, backed by public funds.
Yokkaichi City handed its reservoir grass-cutting to nine goats, dropping annual costs from $5,000 to $3,100. Meet the hungriest grounds crew in Japan and the quiet comeback of goat grazing.
In 2002, Japan's Kindai University pulled off the world's first full-cycle bluefin tuna farming. Two decades on, the major seafood companies are walking away and commercial output is fading. The irony: the headwind is the recovery of wild tuna stocks. A look at the gap between sustainable and profitable.
A Japanese radiative cooling film that stays below air temperature in direct sun, with zero electricity. How SPACECOOL dumps heat into space, its 29% energy cut in Saudi trials, and why passive cooling matters as the planet warms.
Japan discards 650,000 tons of small electronics a year, yet recovers only about 15%. The rest mostly leaks abroad through an untracked invisible flow. On June 5, 2026, the Environment Ministry picked six pilots enlisting movers and couriers to keep the metals home.
With water that is neither sea nor fresh, Okayama University of Science is trying to farm salmon through its entire life cycle on land. If it works, the university calls it a world first. We unpack the technology behind it, why salmon is the hardest fish to farm this way, a 250-year-old salmon town's role, and the global scramble for farmed salmon.
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.
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.
A team from Hokkaido University, Tokai University and Sapporo Maruyama Zoo has bred the slender shrew in captivity for the first time anywhere. Here is how they pulled it off with a mammal that cannot skip a meal, and why it matters for one of the smallest endangered mammals on Earth.
It has its own asteroid and is a prefectural symbol, yet for over 60 years the Musashi stickleback officially didn't exist. How an ice-age survivor near Tokyo finally became a named species, Pungitius nakamurai.
Electronics giant Panasonic hosted a Tokyo adoption event where 193 rescue dogs and cats met would-be families. A look at why a tech company backs animal welfare, and the company-NPO-newspaper model behind it.
In the American South, kudzu is a notorious invasive weed. In Japan, its flower yields tectorigenin, a supplement compound. A RIKEN team has now decoded how the flower makes it and brewed it in yeast, with no kudzu required.
A team led by the Nagoya Institute of Technology has found that water vapor can accelerate bond exchange in vitrimers, a third class of plastic that could finally make 'unrecyclable' thermosets repairable and reusable.
A baby red-shanked douc langur named Mee — from a species called the world's most beautiful monkey — has gone on display at Yokohama Zoorasia. We look at what this critically endangered birth means, and at Japan's habit of naming zoo animals by public vote and following each individual's life story.
