drugs effect on spider web

In 1995 a group of NASA scientists repeated and refined some earlier tests on the effect that various drugs have on the web building abilities of the common garden spider.

Beauty and Beast…Green vine snake

Green vine snake

This is the Green vine snake (Ahaetulla nasuta), a slender tree snake found in India, Sri Lanka, Bangladesh, Burma, Thailand, Cambodia and Vietnam. The snake is mildly venomous, and its bite causes swelling and pain. They feed on frogs and lizards. There is a widespread myth in parts of southern India that the species uses its pointed head to blind its human victims.
