It is an oversimplification to say that science is always changing. Although well-established theories may be overturned on rare occasion, scientific knowledge builds on prior knowledge. Scientific methods, fields and discoveries are predominantly cumulative, whereas pseudoscience fails to progress.
“The history of science is indeed a graveyard of theories, but the fact that science keeps changing is a mark of its strength. It keeps changing because the world is complex and full of wonder. That isn’t a problem; it’s the engine that drives scientific progress.”

Hey all, I reached out to the PO of my NIGMS MIRA to ask if the gov't shut down, and rescheduling of study sections, might allow for some accommodation to the standard rule that PIs cannot resubmit a MIRA while their MIRA (or other RPG) is under review (waiting in scores or summary statements) 🧪
