Closing the Empirical Loop: Autonomous AI Agents Conduct End‐to‐end Research With Human Participants

Advanced Science, EarlyView.
A multi‐agent AI system autonomously executes the complete scientific workflow, from hypothesis to manuscript, across three psychological studies involving 288 participants. The system designs experiments, collects real world data, develops analysis pipelines, and writes manuscripts with theoretical rigor comparable to experienced researchers.

Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites

Advanced Science, EarlyView.
Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

Advanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.
