Biotech meets DIY hacker culture, sparking new wonders and worries

I know these biohacker spaces and whatnot are just getting started up, but more often than not, it seems like they're re-inventing the wheel.

DNA barcoding is old hat, and biofuel production using e.g. algae has been done before.

It's great that these ventures are sparking interest in the community at-large, but they aren't really advancing scientific knowledge forward as much as they're portrayed.
