The 2023 Nobel Prize in Physiology or Medicine was awarded to Katalin Karikó and Drew Weismann for their contributions to developing the fundamentals that led to life saving mRNA vaccines. Although funding and support were not always assured on their road to the Nobel, Katalin Karikó tells Roland she used these setbacks to drive her towards success.

Also this week, NASA Ames researcher Jacob Kegerreis details how Saturn got its rings. Hint: It’s a smashing story.
