We've got big news for all you math nerds out there because someone has just discovered the largest prime number so far, which is maybe not so helpful for mathematicians,

but thrilling for math geeks. If you want to understand numbers, then you need to understand

primes. This is more a feather in the cap for the folks who care about this kind of thing.

It's Friday, November 8th, happy Science Friday. I'm SciFri producer Rasha

Auretti. Discovering a new giant prime number is hard work. I mean, we're talking about

souped up computers and fancy processing chips and software running day and night, all to find the most ginormous prime

number. So go ahead, take your guesses on what that number is, and here's a tip. Maybe multiply

it by a few trillion over and over and over again. That reveal is coming up soon, but first,

let's check in on this week in science.

Here's Ira Flato.

This week, science was on the ballot in many states.

Voters weighed in on issues like drug legalization, money to fund climate programs, and of course, abortion rights.

Ten states voted on the issue, and in seven of them, voters chose to protect or expand abortion rights.

Here with more of the news of this week is Tim Revel, executive editor at New Scientist.

He's based in Merry Old London, England. Welcome back, Tim.

Hi, Ira. Thanks for having me, and happy 33rd birthday. Thank you very much.

All right, let's start with these seven states that voted to protect abortion rights. What are they?

Yeah, so those states are Arizona, Missouri, Maryland, Montana, Nevada, New York, and Colorado.

And there you had a combination of voters formerly voting to enshrine existing abortion

rights and also in the case of Arizona and Missouri actually expanding them too.

And what about the states that rejected those measures? Yeah, so Florida, Nebraska and South
