Hello, faithful listeners. Sam here to say a quick thank you for tuning in this week. I mean,

clearly, you love hearing us, but did you know we also love hearing from you? So go ahead, rate and

review us on your favorite listening platform and tell us what science you want to learn more about

these days. It's honestly way more fun that way, and it really helps us out.

All right, on to the show.

You might have seen some interesting headlines around recently,

like, these salmon got high on cocaine,

and scientists gave cocaine to salmon. If you're anything like me,

we're asking them. We have one of the authors of that study on the show, Dr. Jack Brand.

And let me tell you, going beyond the headlines, as we love to do here,

there are some fascinating insights into how pharmaceuticals pollute our waterways and what the

downstream effects are on the wildlife who live there. Before that, we'll look into a recent

study that says our brains struggle to make connections when we're stressed out. I mean,

very relatable. And later, PCOS or polycystic ovarian syndrome has a new name and for good reason.

We'll talk about why and what it all means for the condition moving forward. Welcome to Curiosity Weekly.

I'm your host, Dr. Samantha Yamin.

the second you get home, you come up with the perfect response. Stress messes with our ability to think and even process memories, sometimes making them stronger, other times making it hard to

remember anything at all. In a new study, researchers found that stress makes it harder to connect

the dots between past memories and new information. See, our memories are malleable.

When we call upon a memory, they often get edited slightly. Our memories can evolve with time.
