Advanced Science, EarlyView.This study elucidates a novel SlJAZ8‐SlWRKY57‐SlAVT6A/SlAVT6B module that effectively channels metabolic flux from primary to secondary metabolism, impacting plant growth, development, and resistance. Two novel vacuolar amino acid exporters, SlAVT6A and SlAVT6B, fine‐tunes trichomes, terpenes, and gibberellins, bolstering spider mite resistance.

Advanced Science, EarlyView.This study represents the first application of a Keggin‐type polyoxometalate, caesium phosphomolybdate (CPM), as a bifunctional redox catalyst for rechargeable Li–CO2 batteries. CPM significantly reduced the potential gap between discharge and charge reactions to 0.67 V, outperforming most reported catalysts. It also exhibited a high discharge capacity

Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals
Advanced Science, EarlyView.Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.
