Baikal endemic and Palearctic species of caddisflies (Trichoptera) build cases from microplastics
Acta Biologica SibiricaPollution of freshwater ecosystems by microplastics is a serious problem. Many studies are related to the pelagic zone and the organisms living in it. However, benthic organisms are most susceptible to this problem in aquatic ecosystems.

Advanced Materials Technologies, EarlyView.Programmable luminescent tags based on organic room‐temperature phosphorescence are shown to be governed by oxygen incorporation during fabrication. Oxygen‐free processing enables immediate phosphorescence activation, controlled thermal preconditioning, and tunable activation doses.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Advanced Materials Technologies, EarlyView.Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

De Karl Bühler à Karl R. Popper [PDF]
Philosophiques, 2002 Popper a passé sa licence sous la direction de Bühler en 1928. Affirmer que Popper a été profondément influencé, non seulement par la théorie du langage de Bühler, mais aussi par sa psychologie, ne correspond pas à l’opinion courante. Le deuxième chapitre de Die beiden Grundprobleme der Erkenntis montre clairement que Karl ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Compact Tabletop Magnetic Resonance Elastography for Mapping Soft Tissue Viscoelasticity
Advanced Science, EarlyView.This work introduces a compact, low‐cost tabletop magnetic resonance elastography platform for high‐resolution viscoelastic mapping in soft‐tissue specimens. Using this method in human colorectal liver metastases, we demonstrate fully automated biomechanical profiling of treatment response and show that heterogeneity‐based metrics outperform ...
