Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, Volume 2, Issue 5, October 2026.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, Volume 13, Issue 56, 9 October 2026.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

PolyG Fibrils Coalesce Into Nuclear Ribbons That Engage Proteostasis Machinery in Neuronal Intranuclear Inclusion Disease

Advanced Science, Volume 13, Issue 56, 9 October 2026.
In NIID, expanded NOTCH2NLC repeats give rise to nuclear polyG inclusions. Tracer‐guided in situ cryo‐electron tomography enables cross‐scale structural analysis from mouse brain to native neuronal nuclei, revealing dense‐core/peripheral‐halo inclusions built from compact polyG ribbons.

Prioritizing Risk Factors in Helicopter Ditching Using Fuzzy Analytic Hierarchy Process

Applied Research, Volume 5, Issue 5, October 2026.
A Fuzzy Analytic Hierarchy Process (FAHP) identified system failure and human factors as the most critical helicopter ditching risks, providing an evidence‐based framework for improving operational risk assessment, emergency preparedness, and aviation safety.
