Everyone loves a good comeback story — but they don’t just apply to athletes and washed-up actors. Revivals can happen for ideas, places — even entire species. On this episode of The Pulse, we explore how and why comebacks happen in the scientific realm. We’ll hear stories about how grizzly bears are starting to rebound, the unexpected revival of Lamarckian evolution, how flatworms regenerate their bodies, and the psychological power of nostalgia.
