Imaging, Mechanics, Construction, and Sonification of Three-Dimensional Spider Webs
Spiders, silks and webs have adapted, survived, and prospered in most ecosystems for millions of years, despite being subjected to environmental and human pressures. They are the proof of an evolutionary success, in part due to the exceptional mechanical and biological properties of their silks but …

Modeling spider webs as multilinked structures using a Chebyshev pseudospectral collocation method
Spiders weave intricate webs for catching prey, providing shelter and setting mating rituals; arguably the most notable of these creations is the orb web. In this thesis we model the essential vibrations of orb webs by first considering a spider web as a multilinked structure of elastic strings. We …

Beaver Dams, Spider Webs, and the Sticky Wicket: An Investigation On What Counts as Technology and What Counts as Knowledge
… from one another. The complexity of a spider web is not matched by many human-made technologies. Beaver dams, beehives, and ant hills are great creations made by non-human animals. Davis Baird has argued that our scientific instruments bear knowledge in important ways, and the idea of …

Molecular dynamics analysis of supercontraction in spider dragline silk
Spider dragline silk is a material that has evolved over millions of years to develop finely tuned mechanical properties. It is a protein-based fiber, used as the main structural component in spider webs and as a lifeline for the spider, and it combines strength and extensibility to give it …

Biomimicry of the spider silk spinning apparatus
<p>Spider silk is known for its extraordinary material properties, being both very strong and extensible. Even though the fibers outperform many synthetic and natural materials, it is impractical to collect industrial amounts of silk from spiders due to their cannibalistic and venomous nature; they …

Molecular identification of silk proteins in the gumfooted lines and attachment discs of the black widow spider, latrodectus hesperus
<p>Silks from araneoid spiders have become an active area of research for material scientists, biochemists, and molecular biologists. Mechanical properties of spider silk such as elasticity, tensile strength, and toughness make the manufacturing of silk for medical sutures, body armor, ropes and …

Expression, purification and characterization of the structural properties of recombinant Pysp1 and Pysp2 spidroins
<p>Spider silk is a natural high-performance biopolymer with superior mechanical propetiies. Although these fibers out perfmm several man-made and natural biomaterials, there are cha llenges to be circumvented before commercialization. One of the silkproducing glands warranting further study is the …

Characterization of the large diameter fibers in egg case silk : identification of a core fibroin, TuSp1, and localization of fibroin-like molecules, ECPs, from the black widow spider, latrodectus hesperus
<p>Araneoid spiders use specialized sets of abdominal silk glands to produce up to seven different types of silks, each with diverse functional properties. At the time of these studies, fibroin eDNA sequences that encode egg case silk had not been reported in the literature. This study used …
