Magnesium‐Based Transient Bioelectronics, Bio‐Optics and Bio‐Scaffolds
Advanced Functional Materials, EarlyView.This paper reviews the state of the art and recent advances in magnesium‐based thin‐film, foils, and scaffolds for applications in transient bio‐optics, bioelectronics and tissue engineering. The design principles, fabrication methods, material properties, and integration strategies are discussed in detail.

An assessment of microplastics in fecal samples from polar bears (Ursus maritimus) in Canada’s North
Arctic ScienceWe assessed the potential for plastic ingestion in polar bears (Ursus maritimus (Phipps (1774)) using fecal analysis. Two methods studies ensured our protocols could effectively recover and identify plastics in feces. First, microplastics (film, foam, or

Advanced Functional Materials, EarlyView.Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

Ursids evolved dietary diversity without major alterations in metabolic rates
Scientific ReportsThe diets of the eight species of ursids range from carnivory (e.g., polar bears, Ursus maritimus) to insectivory (e.g., sloth bears, Melursus ursinus), omnivory (e.g., brown bears, U.

Advanced Functional Materials, EarlyView.The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Polar bear visits to human infrastructure increase with sea ice loss, not poor body condition
Arctic ScienceClimate warming has reduced Arctic sea ice, forcing some populations of polar bears (Ursus maritimus Phipps, 1774) to spend more time on land and increasing the potential for encounters with humans.

Advanced Functional Materials, EarlyView.Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...
