Advanced Science, EarlyView.ABSTRACT Current clinical approaches for knee cartilage repair are often limited by hypertrophy and fibrosis in the regenerated tissues. A decellularized tissue‐engineered hyaline cartilage graft (dLhCG), composed of a type II collagen‐based extracellular matrix, has been developed to overcome this limitation.

Democracia em algoritmos: perspectivas sobre ciberdemocracia, Big Techs e o papel das redes sociais no crescimento da extrema-direita contemporânea [PDF]
Com o avanço das tecnologias, as redes sociais se tornaram parte fundamental da vida em sociedade, e também da vida política. Nos últimos 10 anos, o aumento de grupos de extrema-direita e de movimentos antidemocráticos preocupa acadêmicos, autoridades ...

Advanced Science, EarlyView.In this study, we demonstrate that low‐intensity ultrasound stimulation enables temporal modulation of midbrain organoid differentiation using a modular multi‐well stimulation platform. In particular, we show that ultrasound promotes the proliferation of dopaminergic progenitor cells.

Halide Perovskite: A Rich Source of Thermal Insulator
Advanced Science, EarlyView.Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping
Advanced Science, EarlyView.This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.
