Ants create a lifeboat in the Amazon jungle - BBC wildlife

Wow, nature never cease to amaze me. Anyway came across this site (Ask Nature) today, which promotes learning and taking hints from nature. The believe is that we will be able to design more effecient and better products if we can do that. Pretty interesting resources can be found there, simply key in what you like to find out about how nature will do certain thing and the results will be shown. Have a look at it! I'm sure you will find a lot of interesting knowledge there.
