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.

When Von Diaz was growing up, her mother sent her away from her home outside Atlanta to spend summers in Puerto Rico. Diaz was born on the island in Rio Piedras, but she found the trips back disorienting. She didn't speak Spanish well. She lay awake at night, pestered by mosquitoes and wilting heat. In her grandmother's kitchen, she found relief in grilled cheese loaded with ground beef picadillo, aromatic olive oil infused with garlic and oregano, and fried cinnamon donuts.

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.

RENEE MONTAGNE, HOST:

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.

NPR is not using her name for her protection.

Terese Marie Mailhot started her new memoir, Heart Berries, while she was in a mental institution, where she had committed herself after a breakdown. The pages bleed with the pain of mental illness, lost love and her family history on an Indian reservation in British Columbia.

It's a collection of essays filled with what she called "heavy material": experiences of poverty, addiction and abuse. But she also says she's finding joy in cultivating art. She spoke with me about her work and her life from Spokane, Wash.

Solar eclipses, supermoons, a star-studded night sky — for us earthlings, looking up into space can be a transformative experience.

But what about the other way around? What is it like to see the entire earth from space? Only a select group of astronauts have had that grand opportunity.

"There was actually a physical moment in time when we answered a puzzle — something that's puzzled us throughout the whole of human history: What did the Earth look like from the outside?" says science historian Christopher Potter.

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."

In the 2012 best-selling novel Me Before You, an idealistic young Englishwoman named Louisa Clark becomes the caretaker of a wealthy businessman left paralyzed from a motorcycle accident. They fall in love. Then tragedy strikes, and Louisa is left to pick up the pieces.

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.
