Petrichor: Your new favorite word

Petrichor is Roar’s favorite word.

1sm

It comes from the Greek “petros,” which means stone, and “ichor,” which is the blood that flows through the veins of gods.

2

It’s the word for the smell that comes after a rain. You know that smell? The one that’s like the time you fell in love during the spring?

3

Or the way it feels to be quiet?

4

The smell of the earth, with plants and animals and dirt and rocks and clouds and everything? When it’s the thickest and lushest and fullest?

5f

That’s petrichor.

Here’s what makes it:

  1. When it’s dry for a little while, plants release oils into the ground1,2.6a

  2. Scientists think these oils stop seeds from growing in tough, dry times36b

  3. Meanwhile, Actinobacteria kick the bucket when it’s dry, releasing something called geosmin46c

  4. When it rains, petrichor and geosmin are released from rocks and dirt, and we can smell it.6d

So it’s all that. Plus stones. Plus the blood that flows through the veins of gods.

Gluteal Crease: Where the Butt Crack Begins

Gluteal crease! The top part of your butt crack!

buttcrack1

A great place to live, if you’re bacteria. Thanks to your g.c.’s warm, “moist” environment, a bouquet of biota feels right at home. Humidity-loving microbes like Staphylococcus and Corynebacteria  delight in hanging out in there (and other warm, moist areas like inside your belly button and in your toe cracks).

buttcrack2

 

There, they scarf down your sweat, and in the process generate what scientists call “butt funk.”1,2

buttcrack3

As an aside, plastic surgeons want you to know the “most attractive” gluteal crease is a v-shaped one.3 In case you were looking for something else to dress up.

Vocabulary Friday: Polyphyodont

Polyphyodont! Animals that continuously replace their teeth!

They shed their chompers like yesterday’s news.

manyteethed1_01

 

You and I replace our teeth only once. We’re diphyodonts.

manyteethed3_01

 

Polyphyodonts lose and grow teeth until they die.

Animals like frogs, lizards, fish, alligators, and sharks are making our tooth fairy go broke.
