X. On the male organs of some of the cartilaginous fishes [PDF]
Philosophical Transactions of the Royal Society of LondonAbstract In a paper on the Torpedo, which was published in the Philosophical Transactions for 1834, I have briefly described the male generative organs of this fish as consisting of two firm oval testes, of vasa deferentia without vesiculae seminales, and of a papilla opening into the cloaca, the common termination of the seminal and ...

Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs
Advanced Science, EarlyView.Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

Advanced Science, EarlyView.This work identifies M1 macrophage‐mediated inflammation as a key driver of BMSC senescence and bone microstructural deterioration at the enthesis. A tissue‐adhesive hydrogel delivering senomorphic small extracellular vesicles suppresses this inflammatory‐senescent cascade and enhances BMSC resilience by inhibiting the cGAS‐STING‐NF‐κB pathway.
