Spider silk possesses a unique combination of high tensile strength and elasticity resulting in extraordinarily tough fibers, compared with the best synthetic materials. However, the potential… Expand
Evolution of supercontraction in spider silk: structure–function relationship from tarantulas to orb-weavers
SUMMARY Spider silk is a promising biomaterial with impressive performance. However, some spider silks also ‘supercontract’ when exposed to water, shrinking by up to ∼50% in length. Supercontraction… Expand
The common house spider alters the material and mechanical properties of cobweb silk in response to different prey.
Many spiders depend upon webs to capture prey. Web function results from architecture and mechanical performance of the silk. We hypothesized that the common house spider, Achaearanea tepidariorum,… Expand
Wet webs work better: humidity, supercontraction and the performance of spider orb webs
SUMMARY Like many biomaterials, spider silk responds to water through softening and swelling. Major ampullate silk, the main structural element of most prey capture webs, also shrinks dramatically if… Expand

SUMMARY Spider dragline silk has enormous potential for the development of biomimetic fibers that combine strength and elasticity in low density polymers. These applications necessitate understanding… Expand
Apports de la radiothérapie avec modulation d’intensité guidée par l’image dans les cancers prostatiques
Resume La radiotherapie represente un traitement majeur du cancer de la prostate localise. En l’absence d’hormonotherapie et en utilisant des techniques d’irradiation conformationnelle « standard »,… Expand
Supercontraction forces in spider dragline silk depend on hydration rate.
Spider dragline silk is a model biological polymer for biomimetic research due to its many desirable and unusual properties. 'Supercontraction' describes the dramatic shrinking of dragline silk… Expand
Plasticity in Major Ampullate Silk Production in Relation to Spider Phylogeny and Ecology
Spider major ampullate silk is a high-performance biomaterial that has received much attention. However, most studies ignore plasticity in silk properties. A better understanding of silk plasticity… Expand
Biomechanical variation of silk links spinning plasticity to spider web function.
Spider silk is renowned for its high tensile strength, extensibility and toughness. However, the variability of these material properties has largely been ignored, especially at the intra-specific… Expand
FLOWS AT THE EDGE OF AN ACTIVE REGION: OBSERVATION AND INTERPRETATION
Upflows observed at the edges of active regions have been proposed as the source of the slow solar wind. In the particular case of Active Region (AR) 10942, where such an upflow has been already… Expand
