Crystalline OLED: Lining Up Molecules Raised Current 1,000-Fold
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.
Fundamental science from Japanese universities and national research institutes.

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.
Why does osteosarcoma cluster in the knees of growing teenagers? A University of Tokyo team, working from an accidental clue in aging research, has pieced together how the cancer starts: an accelerator gene (c-Myc), a brake gene (p53), and a signal from the bone's growth plate. It could reshape drug discovery for a rare cancer.
Toho University stroked infants on the head, back and belly. Only the back calmed them, at about 10.5 cm/s. In mouse pups raised without a mother, the response never appeared at all.
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.
