Astronomers found the oldest known black hole this week and it's huge.

It completely changes the game in understanding how these objects form and that all of this action starts really early on.

It's Friday and November 10th and just double checking my notes and yep it's Science Friday. I'm Cyfry producer D. Peter Schmidt, so we used to think that the only way you could get a black hole

was through the collapse of a dying star, but as of this week astronomers confirmed a theory that

some of the earliest black holes were made through the condensation of clouds of gas instead, thanks to confirmation from Chandra Observatory and the relatively new

JWST telescope. We'll get to that story in a bit but first Ira and guest

Sophie Bushwick talk about the biggest science stories of the week.

Highly processed foods, ultra processed foods, have been getting a lot of attention recently,

but exactly what are they?

And what's the research linking them to your health

Welcome back.

Thank you.

How do you define ultra-processed food?

Well, that's the tricky thing because different researchers

define it a little bit differently.

But in general, if something's ultra-processed, it's something you couldn't make at home.

It's got an additive to maybe increase its shelf life that you wouldn't be able to find in your standard

grocery store or it was prepared using an industrial process that you couldn't

handle in a regular kitchen. So a lot of foods are processed but ultra processed goes a set beyond that.
