Spiders are a source of intrigue and fear, and several myths exist about their medical effects. Many people believe that bites from various spider species cause necrotic ulceration, despite evidence that most suspected cases of necrotic arachnidism are caused by something other than a spider bite.

Behavioural Processes, 2005
Simple heuristics may help explain how even a spider, despite its minute brain, can be disturbingly intelligent. Hutchinson and Gigerenzer suggest that the generalist-specialist distinction (or more accurately the predictability-unpredictability distinction) may be related to a species' level of reliance on simple heuristics, and spider behaviour may ...

Over the last three decades, the fossil record of spiders has increased from being previously biased towards Tertiary ambers and a few dubious earlier records, to one which reveals a much greater diversity in the Mesozoic, with many of the modern families present in that era, and with clearer evidence of the evolutionary history of the group.

Current Opinion in Neurobiology, 2004
Spiders have highly developed mechanosensory systems, some of which provide access to forms of stimulation alien to our own sensations. Studies of hair-shaped air movement detectors (trichobothria) and tactile sensors have uncovered an outstanding refinement of the processes of stimulus uptake and stimulus transformation, which reflect details of both ...

Chemistry – A European Journal, 2007
AbstractCareful analysis and comparison of optical and electrochemical data available in recent literature for multi‐thiophene molecular assemblies suggested a few basic rules for the design of structurally simple and easily accessible oligothiophenes endowed with properties not far from those exhibited by much more complex and synthetically demanding ...

Spider Venoms and Spider Toxins
Journal of Toxicology: Toxin Reviews, 1998AbstractSpider venoms and toxins are useful tools for the study of ion channels and synaptic functions of neurons in vertebrates and invertebrates. The components of spider venom, such as proteins, peptides, polyamines and bioamines, are species-specific. The various functions of these toxins are reviewed in this paper.
