Mini-DNA replicator

This is pretty amazing:

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.

Copying DNA is important for a number of medical tests, such as diagnosing tuberculosis. The hope is that devices like this may make high-tech medicine more readily available in developing countries.

Maybe it’ll bring down medical costs in a few developed countries, too.
