One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

Advanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

Advanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Anterior Cruciate Ligament Reconstruction Using a Hollow Ligament Advanced Reinforcement System Semitendinosus Autograft Combined With Anterolateral Complex Augmentation Using Gracilis

Arthroscopy Techniques, EarlyView.
Abstract This technical note describes an alternative surgical technique for anterior cruciate ligament (ACL) reconstruction combined with anterolateral complex (ALC) augmentation. The procedure uses a hollow ligament advanced reinforcement system (LARS), along with semitendinosus and gracilis tendons as grafts.

Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing‐Centric Review

Macromolecular Rapid Communications, EarlyView.
Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.
