Scientists have created a method that allows human urine to be transformed into a hard mineral present in bones and tooth enamel.
The research, funded by the US Defense Advanced Research Projects Agency (DARPA), uses yeast to break down urine into hydroxyapatite, a form of calcium needed for bone and dental implants.
Hydroxyapatite isn’t just useful for implants — the researchers involved in the project noted that the material could be used in archaeological restoration, as a biodegradable alternative to plastics, and as a building material for a variety of projects. Their findings were published May 6 in the journal Nature Communications.
