Chromatic anomalies in Bothrops jararaca (Serpentes, Viperidae): Does xanthism affect survival? [PDF]
This article describes, for the first time, the xanthism in two specimens of B. jararaca. It also describes the snakebite caused by one of these specimens, followed by a discussion on the adaptive advantages (e.g.

REWW‐ARM—Remote Wire‐Driven Mobile Robot: Design, Control, and Experimental Validation
The Remote Wire‐Driven robot “REWW‐ARM” demonstrates a new concept of remote actuation that separates electronics from harsh environments while retaining closed‐loop control. Combining tendon‐sheath mechanisms with decoupled joints, it achieves efficient power transmission and autonomous locomotion, manipulation, and underwater operation, suggesting ...

This paper introduces an origami‐inspired, lightweight, reconfigurable instrument for robot‐assisted minimally invasive surgery. Its foldable design enables tiny access, tunable compliance, and multifunctionality, serving as a tool introducer or deformable grasper that safely manipulates delicate bowel tissue.

The Effect of Silk on the Stabilization of Labile Enzyme Lipoxygenase
Entrapping lipoxygenase within silk significantly extended its stability from under 24 h to 10 days. Variations in silk molecular weight and freeze‐drying conditions influenced silk properties and enzyme interactions. This stabilization is leveraged to develop a linoleic acid electrochemical biosensor, integrating lipoxygenase with horseradish ...

An injectable CNC–PNIPAM hydrogel is developed for intrauterine co‐delivery of levonorgestrel and botropase. This platform reprograms uterine natural killer cells toward an immune–tolerant phenotype and enhances endometrial receptivity marker expression. The results demonstrate a promising strategy to counteract endometriosis–associated infertility and

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...
