Crowd-funding: Help Support Research into Using Bacteria to Clean Up the Environment

I've been interested in crowd-funding science for a while. Science is one of the best investments a society can make, so why not let society invest in it directly? There are many research proposals people have made on different crowdfunding websites, but here is one that is relevant to the interests of this show:

Directing the Evolution of Bacteria to Clean Up Toxic Waste

This research team is using directed evolution to develop strains of Pseudomonas aeruginosa that can chelate and remove heavy metal contaminants from the environment. They're trying to raise money directly from the public to support their research. If you want to participate in this project, at least indirectly, you can donate and/or spread the word!

From the site: "Heavy metal pollution is more common than most people realize and it causes serious environmental and health problems. Our research aims to clean up this toxic waste using organisms modified by a process called directed evolution."
