Ghost Whale. Floating Inferno. Forever Young.

What do the world's rarest whale, a luxury liner that became a floating inferno, a supervolcano with a plumbing problem, and a gut bacteria experiment that made old brains act young again have in common? All four had more going on beneath the surface than anyone expected. In this episode of Gotta Be Kidding Me, host Tammy Coron covers four stories where the deeper you look, the weirder it gets.

We cover a spade-toothed whale known to science for 150 years but never once seen alive, finally yielding its secrets after washing ashore in New Zealand and revealing nine stomach chambers, hidden vestigial teeth, and a century and a half of unanswered questions; the S.S. Morro Castle, a 1934 luxury cruise liner that caught fire off the New Jersey coast, killing 137 people and triggering an investigation so tangled and inconclusive it became a second disaster all its own; a study in Science that completely rewrites the textbook on Yellowstone, replacing the classic mantle plume story with something far stranger, a sideways "mantle wind" and a subterranean system that's more sluggish crystal mush than underground lake of fire; and a rodent experiment that transplanted gut microbes from young mice into old ones and watched the older animals' brains physically rewrite their gene expression back toward youth.

A mystery whale, a maritime catastrophe, a supervolcano that doesn't work the way we thought, and a gut-brain connection that keeps getting weirder, all in under eight minutes.
