A monumental Covid vaccine safety study of 99 million vaccinated people confirms just how rare adverse effects are and combats growing vaccine misinformation. Co-director of the Global Vaccine Data Helen Network goes through the results of this massive study. 

This week, Science in Action is bringing you not one, but two extraordinary astronomical discoveries. First, Webb Fellow Olivia Jones on the star hidden in the heart of only supernova visible from Earth. Second, astrophysicist Samuel Lai on what is possibly the brightest object in our universe – a whopping 500tn times brighter than our sun – a star eating quasar. 

And Roland chats with biologist Charlotte Houldcroft who was one of the first to blow the whistle on an absurd, AI generated image which somehow made it through the peer review process.
