You’ve heard of the CSI effect, right? It’s this wacky “syndrome” whereby we’ve watched so much CSI Miami and Law and Order that we can’t fully put our weight behind a verdict without some solid DNA evidence. I guess it’s easy to forget that we had an entire legal system sans DNA for quite a while. In any case, we’ve apparently got an itch to be a bunch of white-coated forensic scientists, which is why we’re so lucky that this crazy, and also beautiful, machine exists in the world. It’s called OpenPCR, and it’ll make science-style DIYers drool. PCR stands for polymerase chain reaction, and it’s a crucial tool for just about any type of modern molecular biology.
