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 Read more about 2 Ways To Fabricate DNA Evidence[…]

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. IBM scientists build Read more about IBM scientists build computer chips from DNA[…]

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 Read more about 44 nm Nanolaser[…]
