In this episode of Tiny Show and Tell Us, we read an email from “baby sis” aka Binky aka Sam’s younger sister Caroline who writes in about an alarming pregnancy test that predates today’s at-home tests. Then we talk about a fascinating study that found a dead salmon showed brain activity in an MRI machine. Spoiler: It wasn’t actually alive, scientists just really needed to rethink MRI analysis.
