Reprogramming breast cancer cells to breast cancer stem cell-like by the POU1F1 transcription factor

This study shows POU1F1 reprograms breast cancer cells into BCSC-like by altering key markers and activating the IL-6/JAK2/STAT3 pathway, suggesting therapeutic targeting of this pathway in hormone therapy-resistant tumors.

Cleavage of cFLIP restrains cell death during viral infection and tissue injury and favors tissue repair

This study shows that cleavage of cFLIP by Caspase-8 limits cell death during viral infection and tissue injury, promoting tissue repair.

Multi-lingual multi-platform investigations of online trade in jaguar parts

The paper investigates online trade in jaguar parts across multiple languages and platforms, identifying 230 posts and 125 jaguar parts, with teeth being the most common item.

Deadly and venomous Lonomia caterpillars are more than the two usual suspects

The paper reevaluates the taxonomy and venom risks of Lonomia caterpillars, identifying 60 species and seven potentially dangerous ones, urging further research on venom diversity and treatment strategies.

Supergene formation: evidence for recombination suppression among multiple functional loci within inversions.

The paper investigates supergene formation in Heliconius numata, showing chromosomal inversions suppress recombination among multiple loci controlling wing patterns, supporting the hypothesis that supergenes evolve through recombination suppression and subsequent recruitment of adaptive mutations.

Distinct cell death pathways induced by granzymes collectively protect against intestinal Salmonella infection

This study shows that granzymes A and B use distinct cell death pathways to protect against intestinal Salmonella infection by balancing bacterial growth and translocation.

Stay clear and dry! How microstructure diversity can offset the hydrophobicity costs of transparency in clearwing Lepidoptera

The paper investigates how wing microstructure in clearwing Lepidoptera compensates for reduced hydrophobicity in transparent patches, finding trade-offs between hydrophobicity and optical transparency.

Deep neural network and field experiments reveal how transparent wing windows reduce detectability in butterflies

The paper tests how transparent wing zones affect moth detectability by birds and DNNs, finding border-touching transparency reduces detectability but size has no effect, with DNNs showing mixed results.

Polysaccharides from the fungus Inonotus obliquus activate macrophages into a tumoricidal phenotype via interaction with TLR2, TLR4 and Dectin-1a

This study shows that acidic polysaccharides from Inonotus obliquus activate macrophages into a tumoricidal phenotype through interactions with TLR2, TLR4, and Dectin-1a.

Ambient light and mimicry as drivers of wing transparency in Lepidoptera

The paper investigates how habitat openness, activity rhythm, and mimicry syndrome influence wing transparency in Lepidoptera, finding that diurnal species and those in open habitats exhibit higher light transmittance.

Granzyme A inhibition reduces inflammation and increases survival during abdominal sepsis.

This study shows that inhibiting Granzyme A reduces inflammation and improves survival in abdominal sepsis by decreasing proinflammatory markers without affecting bacterial load.

Transparency in butterflies and moths: structural diversity, optical properties and ecological relevance

This study examines transparency in 123 Lepidoptera species, revealing its structural basis, optical properties, and ecological relevance in thermoregulation and vision.

Transparency, a better camouflage than crypsis in cryptically coloured moths

The paper tests if transparency reduces detectability in cryptically coloured terrestrial prey by comparing survival rates of transparent, opaque, and wingless artificial moths in predation experiments.

Generalisation behaviour of predators toward warning signals displayed by harmful prey: answers from a videogame played by humans.

This study uses a video game to investigate human generalisation behaviour toward warning signals of harmful prey, finding that learning is more efficient in simpler communities and that visual similarity affects prey vulnerability.
