quote[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.
"I hope this will make PCR more available," says Victor Ugaz of Texas A&M University in Texas, US, whose group made the new device. He says the system could enable DNA-based tests to be carried out in the field or in developing countries, where large, expensive laboratory equipment is neither practical nor affordable.]
I thought this was pretty cool.
For Karen...
