Best Viewed with IE or Opera. Sorry, Firefox works, but loses some sidebar layout,
'my profile' and other stuff... Anybody with a fix, please leave a comment. Many thanks in advance.

That said, if you must use Firefox (and I don't blame you, it's become my browser of choice, too)
...get the "IE Tab" extension. This allows you to view problem pages with the IE rendering engine. Very cool!

The Return of the Puppet Masters.- SCIENCE REPORT

January 17, 2006
Posted by Carl Zimmer
 
Are brain parasites altering the personalities of three billion people? The question emerged a few years ago, and it shows no signs of going away.
 
I first encountered this idea while working on my book Parasite Rex. I was investigating the remarkable ability parasites have to manipulate the behavior of their hosts. The lancet fluke Dicrocoelium dendriticum, for example, forces its ant host to clamp itself to the tip of grass blades, where a grazing mammal might eat it. It's in the fluke's interest to get eaten, because only by getting into the gut of a sheep or some other grazer can it complete its life cycle. Another fluke, Euhaplorchis californiensis, causes infected fish to shimmy and jump, greatly increasing the chance that wading birds will grab them.
