Largest DNA-Based Computational Circuit Created 57
angry tapir writes "Researchers from the California Institute of Technology have built [abstract] what they claim is the world's largest computational circuit based on DNA (deoxyribonucleic acid), using a technology that they said could easily scale to even greater complexity."
Adds reader cwmike: "The researchers formed 130 different synthetic DNA strands that can be used to compose logic circuits. From this source material, they created one 74-molecule, four-bit circuit that can compute the square root of any number up to 15 and round down the resulting answer to the nearest integer. In their setup, the multi-layered strands of DNA are fashioned (see video) into biochemical logic gates that can perform the basic Boolean AND, OR and NOR operations executed by today's transistor-based computer processors."

Just look at the word: "deoxyribonucleic acid".
First: deoxy. Removal of oxygen. Now we know oxygen is important for life. This will make us all suffocate!
Then: nucleic. It's nuclear! Not only will we suffocate, we will also be irradiated!
Then: acid. Not only will we suffocate and get irradiated, we will also get vitriolised!
You see, three dangers in one! And who knows what hidden dangers are in the ribo part!
Oh, and they will tell you that we all have it in our bodies anyway. Well, how did it get into our bodies? It's just proof that the contamination is already far too widespread!
And sometimes you will even get a biologist admit that our death is preprogrammed in the DNA in our body. Therefore, remove all the DNA, and you'll live forever! :-)
