Lots of makers sent this in today, a $10 DNA replicator… Ben writes –
A pocket-sized device that runs on two AA batteries and copies DNA as accurately as expensive lab equipment has been developed by researchers in the US. The device has no moving parts and costs just $10 to make. It runs polymerase chain reactions (PCRs), to generate billions of identical copies of a DNA strand, in as little as 20 minutes. This is much faster than the machines currently in use, which take several hours.
