Improved Black Widow Spider Optimization Algorithm Integrating Multiple Strategies [PDF]
Entropy, 2022 The black widow spider optimization algorithm (BWOA) had the problems of slow convergence speed and easily to falling into local optimum mode. To address these problems, this paper proposes a multi-strategy black widow spider optimization algorithm ...

Molecular architecture of black widow spider neurotoxins [PDF]
Nature Communications, 2021 The venom of Latrodectus spiders contains seven Latrotoxins (LaTXs), among them α-latrocrustatoxin (LCT) and δ- latroinsectotoxins δ-LIT. LaTXs bind to specific receptors on the surface of neuronal cells and target the molecular exocytosis machinery ...

Structural Characterization of Black Widow Spider Dragline Silk Proteins CRP1 and CRP4 [PDF]
Molecules, 2020 Spider dragline silk represents a biomaterial with outstanding mechanical properties, possessing high-tensile strength and toughness. In black widows at least eight different proteins have been identified as constituents of dragline silk. These represent

Fine structure of the intercalated disc and cardiac junctions in the black widow spider Latrodectus mactans [PDF]
Applied Microscopy, 2020 Arthropods have an open circulatory system with a simple tubular heart, so it has been estimated that the contractile pumping structure of the cardiac muscle will be less efficient than that of vertebrates.

Chromosome-level genome assembly of the black widow spider Latrodectus elegans illuminates composition and evolution of venom and silk proteins. [PDF]
Gigascience, 2022 Background The black widow spider has both extraordinarily neurotoxic venom and three-dimensional cobwebs composed of diverse types of silk. However, a high-quality reference genome for the black widow spider was still unavailable, which hindered deep ...
