Naturalistic stimulation changes the dynamic response of action potential encoding in a mechanoreceptor

open access: yesFrontiers in Physiology, 2015
Naturalistic signals were created from vibrations made by locusts walking on a Sansevieria plant. Both naturalistic and Gaussian noise signals were used to mechanically stimulate VS-3 slit-sense mechanoreceptor neurons of the spider, Cupiennius salei ...

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

The complete mitochondrial genome of Trichonephila clavipes (Araneae: Araneidae)

open access: yesMitochondrial DNA. Part B. Resources, 2021
Trichonephila clavipes (Linnaeus, 1767) is known as a golden silk orb-weaver and belongs to the family Araneidae. T. clavipes is one of the few spider species whose genome has been reported and model organism for a molecular biology. Here, we present the

Mistletoe‐ and Mussel‐Inspired Fabrication of Hierarchically Structured Protein‐Cellulose Scaffolds From Biomolecular Condensates

open access: yesAdvanced Materials, EarlyView.
Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...

The efficacy of augmented reality exposure therapy in the treatment of spider phobia—a randomized controlled trial

open access: yesFrontiers in Psychology
The evidence for the use of Augmented Reality (AR) in treating specific phobias has been growing. However, issues of accessibility persist, especially in developing countries.

The brown spider Loxosceles similis (Araneae: Sicariidae): complete mitochondrial genome sequence

open access: yesMitochondrial DNA. Part B. Resources, 2019
The Brazilian brown spider Loxosceles similis (Moenkhaus, 1898) is, like others from the same genus, an arachnid that can cause serious accidents, which is called loxoscelism.

Phase Diagrams Enable Solid‐State Battery Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but

Formulating research questions in social science research

open access: yesThe Journal for Transdisciplinary Research in Southern Africa
Formulating clear and focussed research questions is a fundamental step in social science research because the questions shape the design, methodology and analysis of the entire study.
