Computing Inside a Living Cell

First time accepted submitter Rozanne writes "The new issue of Stanford Medicine magazine has a story on Stanford professor Drew Endy's creation of microscopic computers out of biological components for use inside living cells. His work is a mash-up of molecular biology and computer engineering: Instead of a computer made of silicon, metal and plastic, it's a computer made of DNA, RNA and enzymes. Endy says biologists are typically confounded at first when he explains how the computers work and how they could be used."

If you want some more detailed explanation, I would suggest reading about what Craig Venter's take on it is. He is one of the principal researchers on the Human Genome Project, and has taken the time to write a book for the layman to grasp the magnificence of what he has found.

At its lowest level, the hardware we use today to store data is prone to errors. Your HDD functions perfectly well misreading data hundreds of times a second. You don't even notice until it becomes especially bad; when the errors overwhelm the ability to check and correct the data. A certain amount of errors are expected, and correctable. The simplest method is a simple checksum. Report the intended length of the message you're sending and the receipient then checks to make sure at least the length is correct. Then you can build in redundancy and error correction through more sophisticated means. These problems have largely been solved in the abstract, so they're not dependent on any particular media.
