A Czech team pooled five studies on what competitive gaming does to the body. Energy use barely moves, 1.3 to 2.5 kcal a minute, while heart rate can jump from 85 to 137 bpm. In Japan, the argument is about the word.
Researchers landing on Nishinoshima must first wade into the sea, gear and all, so no seed comes ashore. Two 2026 studies show why: seabirds, not people, brought the plants.
In 200 colorectal cancer patients from Tokyo and Osaka, 44.8 percent of tumours carried a gut bacterium's mutational signature, rising to about 70 percent under 40. The damage may predate the age of ten.
A rock punched through a New Jersey ceiling on July 16, 2024. The homeowner sealed the pieces in jars within minutes, letting a team with the Institute of Science Tokyo and JAMSTEC read traces of ancient asteroid brine.
A German team had 50 students play Super Monkey Ball on a Wii and then work an arthroscopy box trainer. The game scores tracked surgical scores. Splatoon 2 did not, and gamer status predicted nothing.
Tohoku University, JAMSTEC and Fuji Electric filmed droplets on a geothermal turbine blade spinning at 430 m/s, and what held on stationary walls did not hold here. Japan itself runs just 607 MW of geothermal.
Japanese researchers held 1.58 tesla inside a 20 mm model in a 7 km/s hypersonic flow, about 2.1 times what a comparable neodymium magnet gives. Heat flux itself, though, was not among the measurements.
The hat, found in 2023, tiles the plane forever without repeating. A Japanese team etched 372,100 of its points into a silicon nitride film, fired a laser, and got back a pinwheel of light with no mirror image.
PET scans of 37 patients whose hallucinations began after age 40 found tau, the protein behind Alzheimer's, in 64.9% of them against 14.9% of controls. They split into three near-equal groups.
Glassy radioactive particles called cesium balls were thought to stay in Fukushima's topsoil. A Kyoto University team found them inside 39 of 52 earthworms, and one 15.5 centimeters down.
Sensitive teeth affect roughly a third of adults in some surveys, and the usual fix is to seal the surface over. A Tokyo Dental College team has shown that 6-MSITC, a compound in Japanese wasabi, pushes dentin-building cells to lay down new tissue instead. It began with a question asked at a sushi counter in Kanda.
A wild boar was seen hunting a live rabbit on Japan's Rabbit Island in March 2024. Researchers say unregulated tourist feeding has swollen the rabbit population, and that leftovers and carcasses draw boars in.
A terbium-doped AlGaN LED from the University of Osaka and Ritsumeikan University emits four colors from a single spot, with wavelengths that barely move as the current rises.
University of Toyama researchers crystallized an OLED's emitting layer inside a practical thin-film stack: up to 1,000 times the current density at 1 volt, and turn-on at 1.33 V.
A team at the Institute of Science Tokyo found resistance genes running harder inside hospital drain biofilm than in the wastewater itself. Why new pipes can backfire.
Chemists at Nagoya University cut a bond inside a flat carbon molecule and rebuilt it, producing figure-eight, bathtub and double-helix nanocarbons that emit spiraling light and trap carbon dioxide. Published in Nature Communications.
Tohoku University and Air Water went after the two bottlenecks that have kept photothermal cancer therapy in the lab for twenty years. IDP1, an artificial protein designed with AlphaFold, kept nanoparticles circulating for 150.5 minutes against 17.8 for PEG, and a 0.5 mm endoscope that fits inside a 16-gauge needle fired an 808 nm laser from inside the tumor at 28 percent less power. In mice, the tumors were gone within 14 days. How that compares with US trials already running in humans.
A bacterium at Okinawa's deep-sea vents grows on electric current alone, building itself from CO2. JAMSTEC has caught electrosynthesis happening in the wild.
Rubbing a sore spot really does help. Kyushu University researchers have identified the touch neurons behind it in mice, a subpopulation called Npy2r-Cre that dampens pain signals in the spinal cord. The PNAS study puts specific cells behind the 1965 gate control theory.
NAOJ puts NINJA on the Subaru Telescope this summer, a spectrograph that grabs 0.85 to 2.5 micrometers in one exposure. Why Japan bet on follow-up, not discovery.
