Make Me Smarter #13: Eggshells are being used to grow new human bones.
Chicken eggshells are mostly made up of calcium carbonate, a substance that also exists in human bones. That’s why researchers at the University of Massachusetts Lowell (UML) believe that eggs are ideal for growing new bone for humans who have suffered injuries to their own skeleton. “There is a great need for developing new and functional materials to repair and regenerate damaged bone,” Gulden Camci-Unal, a professor of chemical engineering at UML who led the research, told Smithsonian magazine in 2019. “At our lab, we like to take unconventional approaches; we look at nature and try to see what we can use that already exists.”
