DNA and its current state

There's a really good review article in the Guardian today about DNA and how we currently understand its operation and importance.

I was surprised to learn that scientists are able to encode writings and even videos onto DNA and decode them later. The information density is huge compared to electronic memory, but the read/write abilities are very slow.

I'm also struck by the fact that nature has provided such a versatile molecule and that humans are now able to capitalize on it.
