The Aromatic Head Group of Spider Toxin Polyamines Influences Toxicity to Cancer Cells

Toxins, 2017
Spider venoms constitute incredibly diverse libraries of compounds, many of which are involved in prey capture and defence. Polyamines are often prevalent in the venom and target ionotropic glutamate receptors. Here we show that a novel spider polyamine,

Molecular Spiders with Memory [PDF]

Physical Review E 76, 021121 (2007), 2007
Synthetic bio-molecular spiders with "legs" made of single-stranded segments of DNA can move on a surface which is also covered by single-stranded segments of DNA complementary to the leg DNA. In experimental realizations, when a leg detaches from a segment of the surface for the first time it alters that segment, and legs subsequently bound to these ...

An overview of Phoneutria nigriventer spider venom using combined transcriptomic and proteomic approaches

PLoS ONE, 2018
Phoneutria nigriventer is one of the largest existing true spiders and one of the few considered medically relevant. Its venom contains several neurotoxic peptides that act on different ion channels and chemical receptors of vertebrates and invertebrates.

A Web of Coagulotoxicity: Failure of Antivenom to Neutralize the Destructive (Non-Clotting) Fibrinogenolytic Activity of Loxosceles and Sicarius Spider Venoms

Toxins, 2020
Envenomations are complex medical emergencies that can have a range of symptoms and sequelae. The only specific, scientifically-validated treatment for envenomation is antivenom administration, which is designed to alleviate venom effects.

The lethal toxin from Australian funnel-web spiders is encoded by an intronless gene. [PDF]

PLoS ONE, 2012
Australian funnel-web spiders are generally considered the most dangerous spiders in the world, with envenomations from the Sydney funnel-web spider Atrax robustus resulting in at least 14 human fatalities prior to the introduction of an effective anti ...

Sparse Image Reconstruction for the SPIDER Optical Interferometric Telescope [PDF]

Proceedings of the 9th International Conference on Photonics, Optics and Laser Technology, February 11-13, 2021, 2019
The concept of a recently proposed small-scale interferometric optical imaging device, an instrument known as the Segmented Planar Imaging Detector for Electro-optical Reconnaissance (SPIDER), is of great interest for its possible applications in astronomy and space science.

Gene and Genome Duplication in Spiders

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In chelicerates whole genome duplications (WGDs) were identified in distinct groups. While there is evidence that Xiphosurans/horseshoe crabs had three rounds of WGD and arachnopulmonates (e.g. spiders and scorpions) had one WGD, in many other arachnid groups no WGD was identified.
