Fasciola hepatica, or liver fluke, causes fasciolosis in humans and livestock. Following ingestion of vegetation contaminated with encysted parasites, metacercariae, newly excysted juveniles (NEJ) excyst in the small intestine and cross the intestinal wall. After penetrating the liver, the parasite begins an intra-parenchymal migratory and feeding...

Executioner caspases, such as caspase‐3, are known to induce apoptosis, but in other contexts, they can control very different fates, including cell differentiation and neuronal plasticity. While hundreds of caspase substrates are known to be specifically targeted during cell death, we know very little about how caspase activity brings about non‐ap...

There is an urgent need for scalable Microphysiological Systems (MPS's)1 that can better predict drug efficacy and toxicity at the preclinical screening stage. Here we present Mera, an automated, modular and scalable system for culturing and assaying microtissues with interconnected fluidics, inbuilt environmental control and automated image captur...

The widow spiders of the genus Latrodectus (Araneae: Theridiidae) have a well-documented global medical significance due to the potent venom many of them possess. This medical importance partially stems from the global range expansion the genus has undergone, facilitated in part by human trade. This expansion has had an impact on human health in co...

Venom compositions include complex mixtures of toxic proteins that evolved to immobilize/dissuade organisms by disrupting biological functions. Venom production is metabolically expensive, and parsimonious use is expected, as suggested by the venom optimisation hypothesis. The decision-making capacity to regulate venom usage has never been demonstr...

The noble false widow spider Steatoda nobilis continues to expand its range globally with possible implications for public health and native species. Of the European Union list of 66 species of invasive plants and animals, none are spiders. S. nobilis is invasive around the world, but its impact on native species has not been fully assessed. Here,...

Spider species across 27 families have been recorded naturally preying upon vertebrates. Intricate three-dimensional webs, predation strategies, and potent neurotoxic venom allow Latrodectus and Steatoda spiders to subdue vertebrate prey that are many times larger and heavier than themselves. Yet, little is known about the behaviour associated with...

Context In recent years, the Noble false widow spider Steatoda nobilis (Thorell, 1875) has expanded its range globally and may represent a potential threat to native ecosystems and public health. Increasing numbers in synanthropic habitats have led to more human encounters and envenomations. Steatoda nobilis bites were previously classed as medical...
