Disclaimer, Disclaimer, Disclaimer!!!
Here you are, the most advanced, the most evolved, the most genetically diverse…
Not to mention the oldest and most populous life-form the planet has ever known.
And, perhaps as you listen to this you are covering the ear lobe of a human ape.
Or, perhaps you are on the houseplant near the window.
You could be hovering in the air riding on a particle of dust.
Or, even just be at rest upon the speaker that is producing this audio.
But wherever you are, remember:
This world would not be alive without bacteria like you
to do all the little things that need to be done.
Those tiny tasks you carry out while going about your day
Make everything else possible.
Yes, occasionally a few of your friends wind up in places where they may not be so welcome.
But, you will always have a home…
pretty much anywhere you choose to
In the water and in the soil,
Within the niches and on the surface,
Beneath the bottom of the ocean floor,
High aloft the upper atmosphere, and
On the skin and in the guts of every living creature.
And as always, right here on
This Week in Science,
Coming Up Next…
Let’s start with the science news
Wildfire Smoke
The smoke is in the air releasing particulates and carbon dioxide – more than is released by India in a year. The WHO has warned that pollution needs to be reduced. And UN officials are meeting during climate week in NYC at the UN general meeting. Some good news: China has vowed to stop relying on coal. It will build no new coal power plants after the year’s end.
3D printed food
Cooking with lasers one layer at a time.
3D printed materials that can feel
Does that maybe make you feel uncomfortable? Should it? I don’t know…

What is in Blair’s Animal Corner?
Seahorse placentas
Which part is more confusing, that a fish makes a placenta, or that a daddy does?
You know what they say, never trust a moth
At least, if you’re a bat, and you’re trying to eat… the moth…

It could be coming from the sun.
Autistic individuals are more likely to be LGBTQ+
Our biases are showing.

Hot BioFuel
What else can you do with nuclear waste? Maybe make biofuel!
Tiny Robots
Aloft on a breeze collecting air pollution data or monitoring an oil spill, these tiniest of robots might be watching our world soon.
Memory Formation
How does it happen that your brain associates a smell with an event?

Want to see what we were talking about at this time last year? Check out this episode of TWIS from 2020 when we talked with Dr. Kevin Croker about dark matter and GEODES. It was a fascinating interview into the possibility of a different way to consider dark matter… kind of like Justin’s story this week. Anyway, there was also a lot of cool science news. Check it out!
I'm the host of this little science show.
