Today’s interesting fact has to do with Spiders and the thread they make.

Spider thread has five times the tensile strength of steel and is stronger then even the best currently available synthetic fibres.

It has been shown that if you have enough silk it is better than Kevlar in bullet proof vests and weights considerably less.

The genes that produce spider thread have been added goats in the section that produces milk, and they have produced some spider silk by extracting it from the milk these goats produce.

They have also added different genes to various bacteria and are hoping to produce the chemicals that get mixed to produce the silk in larger quantities.

Once they have the chemicals needed in large enough quantities all that will be needed is something that reproduces the spider’s spinneret.
