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 ...

Optical Identification of the Shortest-Period Spider Pulsar System M71E [PDF]
The Astrophysical Journal, 2023 M71E is a spider pulsar (i.e., a millisecond pulsar with a tight binary companion) with the shortest known orbital period of P=53.3 min discovered by Pan et al. (2023). Their favored evolutionary model suggests that it bridges between two types of spider

First report of brown widow spider sightings in Peninsular Malaysia and notes on its global distribution [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2015 Background The brown widow spider (Latrodectus geometricus Koch, 1841) has colonised many parts of the world from its continent of origin, Africa. By at least 1841, the species had successfully established populations in South America and has more ...

Surrounded by Spiders! New Black Widows and Redbacks in the Galactic Field [PDF]
, 2012 Over the last few years, the number of known eclipsing radio millisecond pulsar systems in the Galactic field has dramatically increased, with many being associated with Fermi gamma-ray sources. All are in tight binaries (orbital period < 24 hr) with many being classical "black widows" which have very low mass companions (companion mass Mc << 0.1 Msol)

Blueprint for a high-performance biomaterial: full-length spider dragline silk genes. [PDF]
PLoS ONE, 2007 Spider dragline (major ampullate) silk outperforms virtually all other natural and manmade materials in terms of tensile strength and toughness. For this reason, the mass-production of artificial spider silks through transgenic technologies has been a ...

Physiological and biochemical characterization of egg extract of black widow spiders to uncover molecular basis of egg toxicity [PDF]
Biological Research, 2014 BACKGROUND: Black widow spider (L. tredecimguttatus) has toxic components not only in the venomous glands, but also in other parts of the body and its eggs. It is biologically important to investigate the molecular basis of the egg toxicity.
