The current drug addiction crisis began in rural America, but it's quickly spreading to urban areas and into the African-American population in cities across the country.

"It's a frightening time," says Dr. Edwin Chapman, who specializes in drug addiction in Washington, D.C., "because the urban African-American community is dying now at a faster rate than the epidemic in the suburbs and rural areas."

José Ortíz and Ethan Leder had never met, but they quickly came up with an unconventional plan to help Puerto Rico.

Ortíz and Leder's personalities are similar: both are high energy, do-er types. "It's all about doing stuff" says Leder. "Not just talk," adds Ortíz.

When Hurricane Maria hit, Ortíz, a 47-year-old flooring business owner, says his "brain was completely obsessed with it." He was born in Mayagüez, Puerto Rico and was 11 when his family moved to the Washington, D.C. area. "I was just trying to get in touch with anyone in Puerto Rico to offer help."

Jacqueline Woodfork drove through the rain and slept on a highway before she finally found shelter from the floodwaters of Hurricane Harvey.

"I saw cars turning around because the rainfall was so heavy and because the exits were all flooded," says Woodfork, 29. Her car battery died on an elevated portion of Interstate 45 after she left her Houston apartment on Saturday.

Hurricane Harvey left a lot of damage — not only along the Texas coastal towns where it made landfall Friday, but also in communities like Sienna Plantation, in Missouri City, about 20 miles south of Houston.

"It's true when they tell you that it sounds like a freight train coming through," Linda Varnado says, "because that's what it is ... and it's a sound that I don't want to hear ever again."

The Hamptons condo and apartment complex in Tampa is quintessential Florida. Lush and modern, the stucco homes are painted in a soft rainbow of pastels. All around are palm trees, Spanish moss and lily pads.

"It is a very quiet place. You have a lot of children that live here. A lot of professionals live here, retirees," said resident Michael Colon, 66.

But on May 19, that tranquility was shattered in an improbable case that involves four young roommates at the complex.

Two of the men are dead and the other two are in jail.

"Illicit cohabitation."

"Psychological evils."

"Racial integrity."

It's difficult to imagine how much the country's language around race and interracial marriage has changed in the past half century.

But just 50 years ago, interracial marriage was prohibited in Virginia and 15 other states.

The Supreme Court's landmark ruling in Loving v. Virginia declared unconstitutional a Virginia law prohibiting mixed-race marriage. The ruling also legalized interracial marriage in every state.

On a sunny morning in Guadalupe Victoria, near the Guatemalan border in the state of Chiapas, Mexico, Hilda Pastor is washing corn in her backyard sink to make tortillas. It's a daily ritual that starts the night before.

"I mix dried kernels, water and a spoonful of cal" — that's calcium hydroxide or slaked lime, "and it soaks overnight," says Pastor, a 48-year-old mother of three.

Researchers seeking to predict how Americans will vote have for years identified an important clue: The more religious you are, the more likely you are to lean Republican.

Conversations with more than two-dozen self-identified "faith" voters in Boone, N.C., suggest that pattern is holding this year, even while revealing the same high level of voter disenchantment evident across the country.

Let's hear the story now of a woman who went beyond the call of duty. She is an artist in Philadelphia. Her task was to create something to welcome Pope Francis to her city later this month. Here's NPR's Marisa Penaloza.

On a muggy Sunday morning in Rockville, Md., the parking lot of the local pet store is organized chaos at its finest. Several hundred people pack the lot looking for a dog to adopt, and they have 50 to choose from. But they'll have to sort through a whole bunch of barking and tail-wagging to do it.

The scene looks like a mix between a fair and speed dating. Volunteers run the check-in table, coordinators walk potential adoptive families through the logistics and people move from dog to dog trying to find a perfect match to take home.

On March 24, 1989, the tanker Exxon Valdez struck a reef in Prince William Sound, Alaska, spilling 11 million gallons of crude oil into the pristine water. At the time, it was the single biggest spill in U.S. history. In a series of stories, NPR is examining the lasting social and economic impacts of the disaster, as well as the policy, regulation and scientific research that came out of it.

It's a blustery, snowy March day when Michelle Hahn O'Leary offers a tour of Cordova, Alaska, situated on the eastern shore of Prince William Sound.

Bob Moses is 78, but he has the same probing eyes you see behind thick black glasses in photos from 50 years ago when he worked as a civil rights activist in Mississippi. The son of a janitor, Moses was born and raised in Harlem. He's a Harvard-trained philosopher and a veteran teacher.

He started a math training program — the Algebra Project — with a MacArthur "Genius Grant" 30 years ago. The goal is simple: Take students who score the worst on state math tests, double up on the subject for four years and get them ready to do college-level math by the end of high school.

As Washington debates changing the immigration system, the demand for immigration attorneys has already jumped, even without new laws in place.

Lawyers such as Jose Pertierra, a veteran immigration attorney, are trained to interpret the law, but Pertierra sees his role as much more.

Every Thursday at 6 p.m. for the past 10 years, Pertierrra is here — on the set of the Spanish language TV studios of Univision in Washington, D.C., near Capitol Hill. He does a segment on immigration where he answers viewers' questions.

Vikki Hankins wants nothing more in the world than to have her civil rights restored. Hankins, 43, lost the right to vote — and many others — when she went to a federal prison for selling cocaine in December 1990. She spent almost two decades behind bars for her crime.

Today, Hankins is an author and an undergrad who dreams of going to law school. She got out of prison four years ago and quickly applied to have her rights — like voting, serving on a jury and becoming a lawyer — restored.

Surrogacy is an idea as old as the biblical story of Sarah and Abraham in the book of Genesis. Sarah was infertile, so Abraham fathered children with the couple's maid. Today, there are many more options for people who want to grow their families — and for the would-be surrogates who want to help.

Macy Widofsky, 40, is eager to be a surrogate.

"I have very easy pregnancies. All three times have been flawlessly healthy, and I wanted to repeat the process," she says, "and my husband and I won't be having more children of our own."

You can see some progress in Haiti two years since the 7.0-magnitude quake hit. But Port-au-Prince is a tour of unrelenting misery and often disturbing images. Things are happening — slowly. You can tell the pace of progress by looking into people's eyes — emptiness looks back at you. Pain is etched on their faces.

You see it in Elicia Andre. We met her back in December at the homeless encampment run by Catholic Relief Services in Port-au-Prince, where she sought refuge after the quake. The charity had just given her $500 to rent an apartment for a year.
