Charge‐Induced Morphing Gels for Bioinspired Actuation
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

The structural and chemical basis of temporary adhesion in the sea star Asterina gibbosa
Background: Marine biological adhesives are a promising source of inspiration for biomedical and industrial applications. Nevertheless, natural adhesives and especially temporary adhesion systems are mostly unexplored.

Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Crown-of-thorns starfish [PDF]
Why ‘crown-of-thorns’? The crown-of-thorns starfish is nearly the largest species of starfish (Asteroidea). It may be 50 cm or more in diameter and can have more than 15 arms. Its ‘crown-of-thorns’ are the long sharp spines that cover its upper surface. What is more, the spines are coated with a saponin toxin, which causes irritation to puncture wounds

ABSTRACT Despite extensive literature on the demand for recreational sports tourism, more research is needed on stakeholders' shared responsibilities for environmental conservation. To address this gap, this study proposed an extended conceptualization of shared responsibility, examining stakeholders' perceptions, expectations and interactions in ...

Laminar fluid ejection device enables high yield and preservation of mRNA and SaRNA LNP formulations
The development of messenger RNA (mRNA) and self-amplifying RNA (saRNA) vaccines has revolutionized modern vaccinology, particularly with the success of lipid nanoparticle (LNP)-based SARS-CoV-2 vaccines.

Recycling of Uridylated mRNAs in Starfish Embryos
In eukaryotes, mRNAs with long poly(A) tails are translationally active, but deadenylation and uridylation of these tails generally cause mRNA degradation. However, the fate of uridylated mRNAs that are not degraded quickly remains obscure.

On some toxinological aspects of the starfish Stellaster equestris (Retzius, 1805)
Whole-body extracts in methanol were obtained from the starfish Stellaster equestris. The crude toxin was fractionated stepwise using diethylaminoethyl (DEAE) cellulose column chromatography.

Abstract A keystone species is one whose influence is disproportionate to its abundance, the absence of which would change the dynamics of an ecological or human community. Despite its widespread use in the scientific literature, there is a limited understanding of how the keystone concept is defined or measured, or applied in practice, and especially ...
