O.K. this post is not about David Bowie's classic album Ziggy Stardust and the spiders from Mars(The first record I ever owned), but their is a connection to Mars, or more precisely N.A.S.A. and Spiders.
The NASA experiments have shown that common house spiders spin their webs in different ways according to the psychotropic drug they have been given. Spiders on marijuana made a reasonable stab at spinning webs but appeared to lose concentration about half-way through. Those on Benzedrine - "speed" - spin their webs "with great gusto, but apparently without much planning leaving large holes", according to New Scientist magazine.
The scientists believe their previous work on the geometry of crystals will help them to devise computer programs that can analyze web-building objectively in order to predict the toxicity of new medicines. "It appears that one of the most telling measures of toxicity is a decrease, in comparison with a normal web, of the numbers of completed sides [of a web]; the greater the toxicity, the more sides the spider fails to complete", the scientists say.
Paul Hillard, spider specialist at the Natural History Museum in London, said researchers first discovered the effects of psychotropic drugs on spiders during experiments at the end of 1960s. The researchers fed caffeine to spiders in hope of making them spin webs in the late evening rather than the early dawn. The result was eccentric webs rather than earlier spinning, he said.see Spider Communication: Mechanisms and Ecological Significance
