New Study Helps To Identify Spiders In International Cargo
2014-10-06 03:49:04

Entomology Today Spiders found in international cargo brought into North America are sometimes submitted to arachnologists for identification. Often, these spiders are presumed to be of medical importance because of their size or similarity to spiders that are known to be toxic to humans. In 2006, after witnessing multiple episodes where harmless spiders were mistaken for toxic ones, Richard Vetter, an arachnologist at the University of California, Riverside, asked other arachnologists...

New Secrets Of Spider Venom Revealed
2013-08-30 09:22:22

Brett Smith for redOrbit.com - Your Universe Online New research from the University of Arizona and Lewis and Clark College in Portland, Oregon has found the venom of the brown recluse and other spiders in the genus Loxosceles produces a much different toxic reaction in the body than previously thought. The finding could eventually lead to more effective anti-venoms, study researchers said. The venom of the brown recluse bite contains a protein that can result in the formation of...

Synthetic Spider Protein Future Of Anti Venoms
2013-05-10 08:51:22

April Flowers for redOrbit.com - Your Universe Online Scientists say they have engineered a spider protein that could be the start of a new generation of anti-venom vaccines, with the potential to save thousands of lives worldwide. Researchers from the Universidade Federal de minas Gerais in Brazil say the new protein, created from parts of the toxin from the reaper spider, may be a promising candidate for developing therapeutic serums or vaccines against other venoms. Part of a family...

Big males outperform smaller ones in head-to-head mating contests but diminutive males make ten times better lovers because they're quicker to mature and faster on their feet, a new study of redback spiders reveals. Published in the current online issue of Journal of Evolutionary Biology, the study shows the importance of maturation in defining mating and paternity success. In field enclosures, researchers simulated two competitive contexts favoring the development of differently sized male...
