  • The Regeneron ISEF is a huge science fair that attracts top talent from all over the world.
  • This year, the competition awarded $9 million in prizes. It has a history of prestigious winners.
  • That can make for a stressful competition, but parents shouldn't add to it, CEO Maya Ajmera said.
