Scientists from China developed a way to prevent teeth from decaying. It starts with taking strands of E. Coli, combining it with proteins derived from the Streptococcus mutans bacteria which causes cavities. I know it sounds weird putting cavities in your mouth along with E. Coli but there is a reason. Scientists have tested this vaccine on rodents in the form of a nasal spray.

This relates to engineering because its is chemical engineering when you combine chemicals. You need to know which chemicals work together and which chemicals do not.
