In this Science Quickly news roundup, we look at the Food and Drug Administration’s surprising change of heart on reviewing Moderna’s mRNA flu shot, a promising new inhaled vaccine that could fight multiple respiratory bugs at once and fresh research that ties air pollution to higher Alzheimer’s risk. We also check in on the latest Artemis II “wet dress rehearsal” and meet a newly discovered spinosaurid dinosaur that turns old assumptions about such dinos’ habitat on their head.
