Heartworm and seal louse: Trends in prevalence, characterisation of impact and transmission pathways in a unique parasite assembly on seals in the North and Baltic Sea

International Journal for Parasitology: Parasites and Wildlife
The ectoparasitic seal louse, Echinophthirius horridus infects harbour (Phoca vitulina) and grey seals (Halichoerus grypus) in the North and Baltic Sea.

Esterified Cholesterol Conjugates Enable LNP‐Mediated mRNA Delivery to the Blood–Brain Barrier Following Intravenous Administration

Advanced Materials, EarlyView.
A cholesterol‐conjugated lipid library enabled the identification of a ligand‐free LNP platform for efficient mRNA delivery to brain endothelial cells via systemic administration. This platform achieves selective BBB targeting without disrupting barrier integrity, and enables modulation of neuroinflammation and vascular function without requiring trans‐

High prevalence and low intensity of Echinophthirius horridus infection in seals revealed by high effort sampling

Scientific Reports
Seal lice (Echinophthirius horridus) are bloodsucking ectoparasites of phocid seals and vectors of pathogens like the heartworm, Acanthocheilonema spirocauda.

A review of pathogens in selected Baltic Sea indicator species

Environment International, 2020
Here we review the state-of-the-art of pathogens in select marine and terrestrial key species of the Baltic Sea, i.e. ringed seal (Pusa hispida), harbour seal (Phoca vitulina), grey seal (Halichoerus grypus), harbour porpoise (Phocoena phocoena), common ...

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

Advanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Biologging reveals rapid movements of harbour seals between freshwater and marine habitats in the subarctic

Frontiers in Marine Science
Biologging tools can provide invaluable information on the movement and behaviour of animals, facilitating the elucidation of ecological dynamics, especially for wide-ranging species, and supporting conservation and management efforts.

Status of the harbour seal (Phoca vitulina) in Southern Scandinavia

NAMMCO Scientific Publications, 2013
The harbour seal population in Southern Scandinavia has experienced repeated declines caused by hunting and epizootics. These events have shaped the current distribution and abundance of the population.

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Underground Signals: The Ecological Power of Root Volatiles

Advanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

Targeted Restoration of the Microbial Tryptophan Oxidative Pathway Ameliorates Autism‐Like Behavioral and Synaptic Deficits

Advanced Science, EarlyView.
ABSTRACT Autism Spectrum Disorder (ASD) is associated with gut microbiota dysbiosis, yet the contribution of specific microbial metabolic pathways remains unclear. Reanalysis of a public ASD cohort revealed reduced functional potential in microbial tryptophan oxidative metabolism.
