Well, let's start at the beginning, Ari.
The universe probably started with the Big Bang.
Very, very beginning.
So, Ari, this story starts with images from the new James Webb Space Telescope of the very, very early universe.
We're talking like 500 million years after the Big Bang, which since the universe is 13.8 billion years old, that's basically less than 5% of the universe's life.
That's Bingjie Wang, an astrophysicist who is part of a team that published a study about one of these red dots in the journal Astronomy and Astrophysics last week.
So long story short, Ari, we still don't know.
They're all very different.
They all have like different features.
The lead author of that study, astrophysicist Anna de Groff, says that our existing models really just don't explain what's going on in this specific case.
You're listening to Shortwave from NPR.
So I reached out to astrophysicist at Yale, Priya Natarajan, and she says this could be one example of how black holes rapidly grew into supermassive black holes, but that this is only one example of a model that she and her colleague, Tal Alexander, actually proposed a while ago.
They thought that black holes created soon after the Big Bang, with big clouds of dust and gas around them, could rapidly grow to become supermassive black holes.
So she thinks more work needs to be done.
Hey Shore Rivers, Regina Barber here.
And because of that, scientists can study illusions to try to understand how the brain fills in those gaps.
A new study in nature neuroscience did exactly this in mice.
With our bi-weekly science news roundup featuring the hosts of All Things Considered.
So this is an example of how the brain fills in the edges of a shape, even when those edges don't exist.
And when researchers at the University of California, Berkeley and the Allen Institute in Seattle showed this image to mice, they found a special group of neurons in mice brains specifically involved in that process of filling in the missing edges.
And today we have the always fun Ari Shapiro.
We're going to miss you, Ari.
Although one limitation of the study is that it's mice.
A mouse can't say whether they see the triangle or not.
So there's lots more to be done before we can make claims about humans.
Okay, Ari, so this new study came out in the journal Scientific Reports, and it's all about how octopuses use different arms for different tasks.
Octopuses have eight arms, and to look at what each arm is doing at a specific point, you have to watch that video eight times.
Just to be clear, octopus researchers have observed some of these arm preferences in lab settings before.
But Kurt Onthank, an octopus researcher at Walla Walla University in Washington State, who's not affiliated with this research, says it's important for us to observe it in the wild, too.
Ari, you are such a great science nerd and you are always welcome on our show.
We're going to miss you.
We love having you on for now.
You can hear more of Ari on Consider This and PR's afternoon podcast about what the news means for you.
This episode was produced by Hannah Chen and Jordan Marie Smith.
It was edited by Burleigh McCoy and Patrick Jaron Watanonan.
And I'm Regina Barber.
Thank you for listening to Shortwave, the science podcast from NPR.
All that on this episode of Shortwave, the science podcast from NPR.
Joe, I took one hit of that shit.
I'm going to show you guys how we make the syrup.
Watch this.
We're going to go down with our grande low-moisture mozzarella.
Train by day, Joe Rogan Podcast by night!
This is a very simple pizza.
Nice stripes of our chow tomato sauce imported
From Italy.
Imported from Italy.
Sea salt, basil, and olive oil.
That is my recipe for my tomato sauce.
No sugar.
Stop putting sugar in your sauce.
And we have our beautiful house-made vodka sauce.
You make it with prosciutto di parma.
I'm getting a hold on.
Matt, tell him.
This is the sterile pizza.
No bromate.
No preservatives.
Sicilian oregano.
We have some beautiful Fior di Latte fresh mozzarella.
Come on, man.
We just like to break up.
Super simple.
Go in the oven.
About eight minutes.
I eat that fucking...
Pecorino.
Take a bite.
Sarah, come get it now.
Both locations.
Call your pizza.
You were so happy.
