Radio Lab: Parasites and More

If you like to learn, even if you’re not particularly scientific, give Radio Lab from NPR a try. Today, like any that I listen, I learned heaps about a topic I’d never even think of. This time that topic was — parasites.

Yes, parasites. Not something we hear about on the daily news or in school or in conversation.

Listening to Radio Lab today, I came to respect, yes, respect parasites and the scientists who study them.

Here’s a bit that I learned that parasites like hookworm caused lethargy in the 19th Century South, which is said to explain in large measure economic slow down, that blood flukes can live in your system for 40+ years and eventually make you sick, and they’re monogamous. And that a parasite that thrives in cats can brainwash a rat it might have wound up in driving rats to fall in love with cats and as a result most likely wind up eaten so that the parasite is back at home in a cat. These parasites can also get in people and cause havoc. Some think there’s a relationship between schizophrenia and cats because after people started keeping cats as pets, schizophrenia became more common.

Parasites can be good. Good parasites are getting wiped out, and new diseases like Crohn’s disease have become common as sanitation has wiped out both good and bad parasites.

I’m not making this up. I came away thinking that nature is just astounding.

You can try Radio Lab here and choose a podcast on such topics as: color, synchronicity, time, God and many more. The tone, music and narrative used in these programs makes it fascinating.
