## Summary

Hosts Daniel and Forbode discuss three engineering breakthroughs: Professor Ibrahim Ozbolat’s team at Penn State developing bio-inks for in-situ 3D printing of hard and soft tissue during surgery; a joint MIT and Harvard project creating a robot to brush patients' hair to reduce nurse workload; and Professor Pen Bai’s team at Washington University in St. Louis demonstrating anode-free sodium batteries that solve dendrite formation by controlling water content in the electrolyte.
