It turns out that you can easily pland DNA at a crime scene – any biology undergraduate could do this: it’s easier than planting a fingerprint. One method requires you to have a sample of the actual DNA, the other requires you have access to the DNA information in a police database.

Centralised DNA databases still sound like such a great idea, especially in the UK, so well known for keeping the integrity of these kinds of details (that’s sarcasm, people).

So, together with the nano lasers, we now have two new technologies for future growth in computer chip capacity. IBM’s technology makes strands of  DNA self-assemble into shapes such as triangles or squares on top of silicon. This assembly acts as scaffolding for semi conducting nanotubes which become a nano circuit board.

This is very very tiny – it’s by far the smallest information carrying line we can create now. Computer chipmakers are running into walls trying to cram more information lines (wires) into a chip, but they can’t make them small enough to fit. This could change all that, if they can build lenses with switching mechanisms small enough so that these lasers can take the place of the wires, which is why people are so very excited about this.
