The next in a series of Mayor’s STEM Nights will be held on May 18 in the cafeteria of Newton North HS. The featured corporate partner for the evening will be DePuy Synthes of Raynam, MA — a division of Johnson & Johnson that develops products for neurosurgery and sports medicine. The event will begin with free pizza at 6PM, followed by an interactive presentation for students at 6:30PM in which DePuy Synthes employees will talk about how they got involved with STEM and how engineers work with surgeons when planning complicated surgical procedures.
