Hello, listeners. Greetings from Curiosity Weekly headquarters. Before we get into the show, I wanted to thank you all for the lovely feedback we've been receiving the past few weeks. It honestly really helps us shape the podcast behind the scenes and tailor our content to what you all are curious about. Not to sound greedy here, but we want more science too, okay? So leave us a rating or review

on Spotify or Apple Podcasts and let us know what you think or what you want us to cover next. Thanks.

As a neuroscientist, there's one thing I know for certain. There's so much about the brain

that we just don't understand.

From deja vu to astral projection to near-death experiences, science has been finding ways

to explain the unexplainable for a long time, particularly out-of-body experiences.

But with the technology and knowledge base available to us today, it seems like we have a little

more understanding about what's really going on there when we feel ourselves existing outside of our

bodies. Here to explain more is Dr. Marina Weiler, a neuroscientist and assistant professor

in the Division of Perceptual Studies at the University of Virginia. Before we talk to Dr. Weiler, I'll look into a new study

that explores when crabs started walking sideways.

And later, we'll dig into research exposing a Korean skincare ingredient

that might be a new ally against antibiotic resistance.

Welcome to Curiosity Weekly.

I'm your host, Dr. Samantha Amin. Let's get started.

There's a saying in some nerd circles that eventually everything becomes crab. It's one of my

favorite old memes and there's actually some truth to it. The flat, wide shell with the tail

tucked underneath and legs spayed out to the sides, that crab-like body plan

has evolved at least five times independently.

Evolution keeps making crab shapes across totally different lineages over and over.

For example, king crabs evolved from hermit crabs, which are not considered true crabs,

and porcelain crabs evolved from a type of lobster.
