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.

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.

Michael Ryan, 45, is a juvenile judge in Cleveland, Ohio. And like many of the kids who end up in his courtroom, he didn't have an easy childhood.

He adored his mother, he tells his son — also named Michael, 19, at StoryCorps in Cleveland, but she was addicted to heroin.

This weekend marks 75 years since President Roosevelt's executive order that sent Japanese-Americans to internment camps.

Roy Ebihara and his wife, 82-year-old Aiko, were children then, and both were held in camps with their families.

At StoryCorps, 83-year-old Roy told Aiko about what happened in his hometown of Clovis, N.M., in the weeks just before the executive order was issued.

Until September, journalist Chadwick Moore says his life had been lived in a liberal bubble — one that burst after he wrote a profile Milo Yiannopoulos for Out Magazine.

Across the U.S., protesters are calling for a "Day Without Immigrants" on Thursday. It's a boycott calling for immigrants not to go to work, in response to President Trump's immigration policies and his plan to build a border wall between the U.S. and Mexico.

Goats and Soda is now running a series on pandemics.

Dangerous viruses like Ebola and MERS are emerging in greater numbers than ever before. We're looking at how pandemics start, how diseases jump from animals to humans and why the number of newly discovered viruses is on the rise.

"I think you work harder if you're haunted by some small darkness," says John Darnielle. And if the work he's produced is any indication, Darnielle is one haunted man.

President Donald Trump and other Republican leaders have been working to repeal and replace the Affordable Care Act. And the millions of Americans who have health insurance through the Obamacare marketplaces aren't the only ones wondering about their fate. Leaders of insurance companies are, too.

If one thing became clear over the course of the 2016 presidential campaign, it's that Donald Trump knows how to keep media attention on himself. If cable television coverage started to stray, a new controversial tweet or remark would draw it back to Trump.

Tuesday is the last day of open enrollment for health coverage for 2017 under the Affordable Care Act. And while Republicans in Congress are working to repeal the law, it's not at all clear what might replace it.

During the campaign, President Trump suggested a nationwide insurance market that would allow insurance plans to be sold across state lines.
