Transgenic Spidergoats Brief

Spider webs are incredibly strong and flexible. It’s no surprise, then, that spider silk proteins may someday form durable artificial ligaments for people who have injured their knees or shoulders. Six different kinds of silk are produced by orb-web weaving spiders. These silk fibers have very different mechanical properties that are so effective they have changed very little over millions of years. How to synthetically develop these silks is one focus of Lewis’ research. The secret to producing large quantities of spider silk is to use “factories” designed to manufacture spider silk proteins that are easily scale-able and efficient. Lewis uses transgenic goats, E.coli bacteria, transgenic alfalfa and transgenic silk worms to produce the spider silk proteins used to create spider silk. Spider silk is 100 times stronger than natural ligaments and 10 times stronger than natural tendons; it is stronger than Kevlar and more elastic than nylon.

The story of one woman's quest to photograph spider genitalia.

The story of one woman's quest to photograph spider genitalia. By day, Nina is online operations manager for American Medical News, a newspaper published by the American Medical Association. But for 13 years, she’s devoted one day a week to behind-the-scenes work at the Field Museum in Chicago: sorting, identifying, and organizing spiders in the museum’s collections, and in the process turning an enthusiast’s knowledge about arachnids into a slightly demented personal project.

Arachnophobes may wanna skip this one....

A new and previously unknown species of spider, Cerbalus Aravensis, (photo) has been discovered in the dune of the Sands of Samar (map) in Israel's southern Arava region along the Israel-Jordan border by a team of scientists from the University of Haifa-Oranim. Cerbalus is the largest arachnid of its type in the Middle East, with a leg-span that can reach up to 5.5" (14 cm). Unfortunately, its habitat is endangered thanks for rezoning for agriculture and sand quarries. [more inside]
