For the first time ever, imports of elastic knit pants surpassed imports of jeans in 2017, according to the U.S. Census Bureau. But big denim-makers are fighting back, says Bloomberg reporter Kim Bhasin.

The blue jeans-stretchy pants rivalry started around 2011, says Bhasin, with athleisure brand Lululemon's push to sell yoga pants and leggings.

"People were really wanting this kind of comfortable feeling on their legs instead of thick denim," he says. "And they would wear it in the gym and slowly that trickled out of the gym and onto the streets."

For the first time, a generation of children is going through adolescence with smartphones ever-present. Jean Twenge, a professor of psychology at San Diego State University, has a name for these young people born between 1995 and 2012: "iGen."

She says members of this generation are physically safer than those who came before them. They drink less, they learn to drive later and they're holding off on having sex. But psychologically, she argues, they are far more vulnerable.

For students starting medical school, the first year can involve a lot of time in a lecture hall. There are hundreds of terms to master and pages upon pages of notes to take.

But when the new class of medical students begins at the University of Vermont's Larner College of Medicine next week, a lot of that learning won't take place with a professor at a lectern.

The school has begun to phase out lectures in favor of what's known as "active learning" and plans to be done with lectures altogether by 2019.

Two summers ago, we met a woman who went by the name Teacup.

"I'm an active heroin user," she told us. "Thirty-three years as a matter of fact."

Venezuela's ongoing political and economic crisis has taken a toll on daily life there.

A crash in oil prices and political instability under President Nicolas Maduro have led to food shortages, and that has prompted almost daily street protests by thousands of Venezuelans.

A 35-year-old protester named Carlos tells NPR's Audie Cornish the food situation is "pretty extreme." NPR is using only his first name for his safety.

Singer and multi-instrumentalist Krystle Warren has been compared to artists like Tracy Chapman and Nina Simone. The latter comparison is particularly intriguing: Not only does Warren share that icon's talent for evocative storytelling, but she also lives in France, as Simone once did.

The Handmaid's Tale by Margaret Atwood is one of a handful of dystopian novels that have seen a boost in sales since the 2016 election. The book tells the story of what happens when a theocratic dictatorship takes over the government and gets rid of women's rights.

A few years ago, Chimamanda Adichie received a message from a childhood friend asking for advice: She wanted to know how to raise her newborn daughter to be a feminist.

Democrat Michelle Frankard of Wisconsin voted for President Trump, and she's hoping she won't regret it.

At the Garden of Eatin', a bustling diner in picturesque Galesville, Frankard is having breakfast with her adopted father, Ken Horton. A dozen shiny electric guitars line the walls, each next to a black-and-white framed poster with the likes of Johnny Cash and Janis Joplin. The deep-seated booths host a variety of regulars and those just passing through.

If you've been watching the Democratic National Convention in Philadelphia on TV, you've probably seen it happen a few times already: Every few minutes, a fresh wave of brightly colored signs — bearing campaign slogans like "Stronger Together" or "Love Trumps Hate" — spreads across the convention floor like wildfire.

Across the U.S., more than 20 million people abuse drugs or alcohol or both. Only about 1 in 10 is getting treatment.

People seeking treatment often have to wait weeks or months for help. The delays can jeopardize the chances they'll be able to recover from their addiction.

If you took a map of Chicago and put down a tack for each person shot last year, you'd need nearly 3,000 tacks.

Of those, 101 would be clustered in the neighborhood of East Garfield Park. That's where 15-year-old Jim Courtney-Clarks lives.

"To be honest, I really don't like it," Courtney-Clarks says. "Every time you look up somebody else is getting killed, and I never know if it's me or somebody I am really close to."

The protests in Chicago have been mostly peaceful. But it's not just about police. This is all happening against a backdrop of gang violence, including the recent killing of a 9-year-old boy who police say was apparently targeted because of his father's alleged gang ties.

These incidents are forcing difficult conversations between parents and kids. And for African-American families, the conversation hits close to home.

Every Thursday night you can find Nathan Fields making the rounds of Baltimore's red light district, known to locals as The Block.

An outreach worker with the Baltimore City Health Department, Fields, 55, is a welcome sight outside strip clubs like Circus, Club Harem and Jewel Box.

In the early evening before the clubs get busy, he talks with dancers, bouncers and anyone else passing by about preventing drug overdoses and how to stop the spread of HIV and other sexually transmitted diseases.

A suspected case of measles. A rabid fox on the loose. A recall of a dye used in tattoos. A drug epidemic that's claiming hundreds of lives.

Those are just a few of the problems that Dr. Leana Wen confronts in a typical week as the Baltimore City Health Commissioner. While they all have to be dealt with, it's clear that heroin is among Wen's gravest concerns. Right now, she's focused on stopping overdoses and saving lives.

There were 104 overdose deaths in Baltimore during the first quarter of 2015, a 49 percent increase over the 70 reported during the same period in 2014.

On a hot, sunny Monday in mid-July, Dr. Leana Wen stood on a sidewalk in West Baltimore flanked by city leaders: Mayor Stephanie Rawlings-Blake, interim police commissioner Kevin Davis, Rep. Elijah Cummings. Under a huge billboard with the web address dontdie.org, she proudly unveiled a 10-point plan for tackling the city's heroin epidemic.

Wen, the city's health commissioner, said she aims to create a 24/7 treatment center, an emergency room of sorts for substance abuse and mental health. She spoke of targeting those most in need, starting with those in jail.

Neighborhoods in Baltimore are still struggling to recover from the riots that broke out following the funeral of Freddie Gray, who suffered a fatal injury to his spine while in police custody. In the aftermath of the unrest, we here at NPR spent many hours trying to understand the raw anger on display. We looked at police brutality, economic disparities and housing segregation in Baltimore.

Our conversations eventually led us to Leana Wen.
