Keep your eyes on the sky on Saturday for an astronomical event visible across

much of the U.S. So this one is like the little rehearsal eclipse. We'll tell you

how to see it safely. It's Friday, October 13th. Ooh, spooky. But don't worry today is

22,000 years ago, thousands of years earlier than anthropologists

originally thought. Remember that? Well, now there's a new study that provides

additional data supporting this earlier arrival of humans to North America.

And in Science, of course, we always welcome new data. And sometimes though

interpreting it means not, well, not so straightforward to do that. Joining me

now to put this find in perspective along with other Science News of the

Week is Maggie Curth, editorial lead at Carbon Plan based in Minneapolis

Minnesota. Maggie, welcome back to Science Friday. Hi, Ira. Thanks for having me.

Nice to have you. Okay. Can you parse this for us? What's in this new study

about when people arrived in North America? Yeah. So this study is kind of a, like

you say, a redo sort of meant to appease some critics and offer a little bit
