Researchers from NTU, Shanghai Jiao Tong University and the University of Tokyo propose UMM-Reflection, which uses reinforcement learning to train full multi-turn reflect-then-revise trajectories on the open unified model BAGEL, letting a single model write its own diagnosis and redraw accordingly with no external scorer at inference. Repair success on initially flawed images rises from 20.6% to 64.9%, GenEval improves from 0.72 to 0.84, the spatial-position sub-score jumps from 0.47 to 0.89, and the unseen WISE benchmark gains 11 points. Code, models and training data are open-sourced.

Pinduoduo turned its agricultural innovation contest into a physical engineering challenge: four finalist teams each built a 50-square-meter (10x5x4 m) smart plant factory from scratch, growing only domestic strawberry varieties with fully domestic technology and requiring unattended remote autonomous control, judged on berry quality and sustainability. The 'Berry Cube' team, combining Shanghai Jiao Tong University with engineering firm Jiqing Technology and strawberry grower Jiaxing Jiamei, found that parameterizing light, temperature, humidity, fertigation and CO2 does not guarantee good strawberries, as biological systems resist standardization.
