Lourdes Garcia-Navarro

Lulu Garcia-Navarro is the host of Weekend Edition Sunday. She is infamous in the IT department of NPR for losing laptops to bullets, hurricanes, and bomb blasts.

Before joining the Sunday morning team, she served an NPR correspondent based in Brazil, Israel, Mexico, and Iraq. She was one of the first reporters to enter Libya after the 2011 Arab Spring uprising began and spent months painting a deep and vivid portrait of a country at war. Often at great personal risk, Garcia-Navarro captured history in the making with stunning insight, courage, and humanity.

For her work covering the Arab Spring, Garcia-Navarro was awarded a 2011 George Foster Peabody Award, a Lowell Thomas Award from the Overseas Press Club, an Edward R. Murrow Award from the Corporation for Public Broadcasting, and the Alliance for Women and the Media's Gracie Award for Outstanding Individual Achievement. She contributed to NPR News reporting on Iraq, which was recognized with a 2005 Peabody Award and a 2007 Alfred I. duPont-Columbia University Silver Baton. She has also won awards for her work on migration in Mexico and the Amazon in Brazil.

Garcia-Navarro got her start in journalism as a freelancer with the BBC World Service and Voice of America. She later became a producer for Associated Press Television News before transitioning to AP Radio. While there, Garcia-Navarro covered post-September 11 events in Afghanistan and developments in Jerusalem. She was posted for the AP to Iraq before the U.S.-led invasion, where she stayed covering the conflict.

Garcia-Navarro holds a Bachelor of Science degree in International Relations from Georgetown University and an Master of Arts degree in journalism from City University in London.

Bailey Davis was a Saintsation — a cheerleader for the New Orleans Saints. That is, until she posted a photo of herself in a one-piece lace bodysuit on her private Instagram account.

The romance genre is a juggernaut that continues unabated.

It's a billion-dollar industry that outperforms all other book genres, and it's remarkably innovative, with a strong tradition of independent and self-publishing.

Kali Uchis has been practicing for her debut release since she was 18 years old. Shut in her room in suburban Virginia, Kali was making mixtapes and dreaming up treatments for imaginary music videos. The Colombian-born singer's major label debut Isolation, out now, is a tribute to overcoming heartache and being your own hero and an appreciation for the musical inspirations that have brought her to this moment.

The Arabic word habibi means "my love," an apt descriptor for Rahill Jamalifard's feelings about her Iranian upbringing and the music she creates. Jamalifard is the frontwoman for Habibi, the Brooklyn-based band that mixes Detroit garage rock with girl group harmonies and surf guitar. The band's newest EP, Cardamom Garden, houses lyrics that move seamlessly between English and Farsi.

Less than two years after Donald Trump won a western Pennsylvania congressional district by double digits, a special election race between a young Democrat and a deeply conservative Republican is now closer than either side had expected. The congressional race is being run in Pennsylvania's 18th district, but the March 13 election is expected to offer clues about how voters will turn out in the November midterms.

Since this frightened mom crossed the border with her son in early 2017, fleeing gang violence in El Salvador, she has felt bewildered by the vast complicated immigration system in the United States.

This is Lulu's log, stardate Feb. 11, 2018, where we explore matters of space, the stars, and the universe.

In the summer of 1967, Linda Walker was at Girl Scout camp in North Carolina when a lightning bolt struck her.

She says she was in a tent with three other girls when they all ran out after the crackle and boom. Walker was on the floor, unresponsive.

"But as Girl Scouts you always keep up with your buddy — you never lose track of your buddy," Walker says. "And my buddy walked out, ran out of the tent without me, but realized I wasn't with her and came back. Had she not done that, I wouldn't be here today ... because she saved my life."

This past week, a FedEx employee from Germantown, Tenn., made a massive discovery — and it wasn't in any packages. John Pace found the largest prime number known to humankind.

And that number goes on to more than 23 million digits.

"So it's longer than anybody really wants to sit down and hear," he says.

If you're not great at math, here's a primer: Prime numbers can only be divided by 1 and themselves.
