Researchers have found that just two to three hours of exposure to furry tarantula – a kind of spider – can help in removing the phobia for spiders that causes the people to be fearful of spiders. Continue reading
Researchers have found that jumping spider (Hasarius adansoni) uses blurring images as a primary means of depth perception by using green color light.
This research has been done by researchers in Japan and published online in the January 27 issue of the journal Science.
Every organism uses different visual systems to check for the distance accurately and reliably such as humans have binocular stereovision. Our eyes are spaced apart and get images from different angles, the distances of which are automatically triangulated by our brain. However, jumping spiders lack this binocular stereovision.

Researchers have developed artificial spider silk by genetically engineered silkworms.
This research has been published online in the journal of Proceedings of the National Academy of Sciences (PNAS).
“This research represents a significant breakthrough in the development of superior silk fibers for both medical and non-medical applications,” Malcolm J. Fraser Jr., a Notre Dame Professor of biological sciences, said in a statement. “The generation of silk fibers having the properties of spider silks has been one of the important goals in materials science.”
Natural spider silks have many of the extra-ordinary physical properties such as higher tensile strength and elasticity than naturally spun silkworm fibers. The spider silks produced artificially through these transgenic silkworms have properties equivalent to that of natural spider silks. Before this research only a small amount of artificial spider silk had ever been produced in the laboratories. Continue reading
