Can we rely on DIY air pollution sensors?

Citizens and activists are using cheap off-the-shelf sensors to collect their own data on air pollution. It's a promising trend, but these devices have serious technical limitations.

Expanding citizen science models to enhance open innovation

This method of crowdsourcing science legwork is ready to expand into other disciplines – and maybe the amateurs themselves can start calling some of the shots.
