Researchers including Peking University's Lin Yang bent undoped diamond nanoribbons to a 1.49% peak strain and found the gradient tunes the light they emit. Strain could replace doping in diamond, where dopants trap charge carriers at room temperature, but the emitted light was measured at 80 K.

Researchers from five institutions lifted a student model 5.34 points over a control on HumanEval+ using 5,664 one-word answers from a code-tuned teacher. None of those answers contained code, so a filter that screens outputs for task content would have passed every one.

A new book from MIT's Senseable City Lab argues that computer vision can quantify streets at a scale pen-and-paper urbanism never reached, and the account of it gives privacy and fairness one line.

A Beijing team turned one woman's fat cells into pancreatic islets, and within two months she stopped needing insulin injections. Nearly three years of steady blood sugar is the longest result reported, in a single patient.

MoOCl2 is metallic along one crystal axis and dielectric along the perpendicular one, and an Okayama-led team used that split to measure a dielectric quality factor of 45.3 in nanodisks on gold, about 5.7 times the plasmonic mode's.

A Peking University-led team matched US forest inventories to satellite productivity and found that heat and moisture extremes arriving together hurt more than either alone, with species-rich plots dipping less and recovering faster.

The catalogue took 14 years and more than 260 institutional visits to assemble. It lifts the known overseas count sevenfold, so roughly 19,700 objects in nearly 30 countries just acquired a citable public record.

DeepSeek Harness is an MIT-licensed developer preview in which the model adapter, tool registry, session log and agent loop are all plugins. The interesting part is what that implies for evaluation.

A new paper says Sora, Genie 3, JEPA and Marble carry no mental state at all. Its own benchmark, 420 of 448 scenes without motion, tests language models instead.

SWE-Bench ProMax puts frontier coding agents on 170 curated refactoring commits. The number that should move procurement is a different one: nearly 60% of unsolved SWE-bench Verified tasks have flawed tests.

Junyue Cao read 21 million cells from 14 organs and says aging arrives in discrete stages. If the staging holds, an intervention has a window rather than a dose.
