The next time you sink your teeth into a soft slice of bread, think about the material training that went into making that bread. Material training is one of many approaches to designing new materials and involves taking a material and applying a repeated training protocol that modifies small-scale structures in the material. The result is the same material that you started with but with new properties. When it comes to that slice of bread, repeatedly kneading the dough changes its gluten structure and results in a stronger and more elastic version of itself -- and also makes for a truly delicious materials science experiment. That science experiment was one of 19 at the first-ever MRSEC Science Slam, recently held online.
