If you thought "eat ze bugs" was bad - Scientists at Pennsylvania State University are developing "an innovative way to recycle human waste into food using a process called anaerobic digestion".
Microbes break down human waste into methane. Another microbe called Methylococcus capsulatus feeds on the methane and produces a protein and fat-rich biomass. The result is "a safe and edible paste that could provide essential nutrients". Yum!
