Stress‐Adaptive Biomaterials With Tunable Yielding Architectures Regulate Organoid Morphogenesis
Small, EarlyView.Granular hydrogels are developed to tune the yield stress levels at which 3D tissue culture matrices undergo plastic deformation. We use these materials to regulate growth‐induced stresses, with demonstrable effects on cancer spheroid invasion and brain organoid morphogenesis.

steel research international, EarlyView.Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
