What do you want to know about world hunger?

One thing we do know is that more than 20 million people are now at risk of starvation and famine. The United Nations is calling it the biggest humanitarian crisis since the U.N. was founded in 1945. Conflict and drought are blamed for the looming crisis in four countries in Africa and the Middle East: Yemen, South Sudan, Somalia and northeast Nigeria.

When New Mexico state Sen. Michael Padilla was a child, he says he mopped the cafeteria floors to earn his school lunch, and he befriended the cafeteria workers so he wouldn't have to go hungry.

"I grew up in foster homes, multiple foster homes," the Democratic lawmaker tells NPR's Rachel Martin. "It's very obvious who the poor kids are in the school."

He says students in circumstances like his often have to watch as other children get served a hot lunch, while they are given a piece of bread — with "maybe a little bit of cheese."

Our global health team has just finished up a series called "What Causes Pandemics? We Do." In radio and online stories, we looked at the causes behind our new hyperinfectious era. We'll continue covering this topic in future stories, but we thought our readers might want a chance to brush up on their pandemic facts. So roll up your sleeves, wash your hands and then try this quiz.

Earth Day is coming up on April 22.

It's an occasion to think about the risks we all face from climate change — and to recognize the toll these problems take on the people in the developing world, who are especially vulnerable. When oceans rise, when drought strikes, the consequences can be dire. People are losing their homes and becoming climate refugees, losing their crops, losing their water sources. Disease-carrying insects are moving into new territory.

A band from the fertile Latin alternative scene in Los Angeles is poised to break out in a big way. Their sound is laid-back lounge grooves, R&B with flavors from Mexico or Brazil and a funky swagger. Their look is matching puffy tuxedo shirts and bow ties, like they're playing a prom in 1976. Even their name is unforgettable: Chicano Batman.

The band Tennis has again taken to the high seas.

Shelby Earl's new album, The Man Who Made Himself A Name, features a song called "Strong Swimmer." She says it started out as a song about herself getting over a relationship — but became more about her stepmother, who had just suffered a brain injury.

It's become an annual tradition for NPR to host a live band in our studios for a full day. This year, we upped the ante and invited around 70 musicians from Washington, D.C.'s National Symphony Orchestra to play the musical interludes between stories on All Things Considered.

It's been five years since the death of Trayvon Martin — and the outrage that sparked the Black Lives Matter movement.

Martin — 17 years old, black and unarmed — was shot by George Zimmerman, a neighborhood watch volunteer in Sanford, Fla.
