Border Trilogy Part 2: Hold the Line

April 6, 2018 - 1:31am

Border Trilogy: 

While scouring the Sonoran Desert for objects left behind by migrants crossing into the United States, anthropologist Jason De León happened upon something he didn't expect to get left behind: a human arm, stripped of flesh.

This macabre discovery sent him reeling, needing to know what exactly happened to the body, and how many migrants die that way in the wilderness.  In researching border-crosser deaths in the Arizona desert, he noticed something surprising. Sometime in the late-1990s, the number of migrant deaths shot up dramatically and have stayed high since. Jason traced this increase to a Border Patrol policy still in effect, called “Prevention Through Deterrence.”

Over three episodes, Radiolab will investigate this policy, its surprising origins, and the people whose lives were changed forever because of it.

 

Part 2: Hold the Line:

After the showdown in court with Bowie High School, Border Patrol brings in a fresh face to head its dysfunctional El Paso Sector: Silvestre Reyes. The first Mexican-American to ever hold the position, Reyes knows something needs to change and has an idea how to do it. One Saturday night at midnight, with the element of surprise on his side, Reyes unveils ... Operation Blockade. It wins widespread support for the Border Patrol in El Paso, but sparks major protests across the Rio Grande. Soon after, he gets a phone call that catapults his little experiment onto the national stage, where it works so well that it diverts migrant crossing patterns along the entire U.S.-Mexico Border.

Years later, in the Arizona desert, anthropologist Jason de León realizes that in order to accurately gauge how many migrants die crossing the desert, he must first understand how human bodies decompose in such an extreme environment. He sets up a macabre experiment, and what he finds is more drastic than anything he could have expected.

This episode was reported by Latif Nasser and Tracie Hunte, and was produced by Matt Kielty, Bethel Habte, and Latif Nasser.

White, Daniel Martinez, Michelle Mittelstadt at the Migration Policy Institute, Former Executive Assistant to the El Paso Mayor Mark Smith, Retired Assistant Border Patrol Sector Chief Clyde Benzenhoefer, Paul Anderson, Eric Robledo, Maggie Southard Gladstone, and Kate Hall.

Border Trilogy Part 1: Hole in the Fence

March 23, 2018 - 3:40am

Border Trilogy:

While scouring the Sonoran Desert for objects left behind by migrants crossing into the United States, anthropologist Jason De León happened upon something he didn't expect to get left behind: a human arm, stripped of flesh.

This macabre discovery sent him reeling, needing to know what exactly happened to the body, and how many migrants die that way in the wilderness.  In researching border-crosser deaths in the Arizona desert, he noticed something surprising.

Over three episodes, Radiolab will investigate this policy, its surprising origins, and the people whose lives were changed forever because of it.

 

Part 1: Hole in the Fence:

We begin one afternoon in May 1992, when a student named Albert stumbled in late for history class at Bowie High School in El Paso, Texas.  His excuse: Border Patrol. Soon more stories of students getting stopped and harassed by Border Patrol started pouring in. So begins the unlikely story of how a handful of Mexican-American high schoolers in one of the poorest neighborhoods in the country stood up to what is today the country’s largest federal law enforcement agency.   They had no way of knowing at the time, but what would follow was a chain of events that would drastically change the US-Mexico border.

This episode was reported by Latif Nasser and Tracie Hunte and was produced by Matt Kielty, Bethel Habte, Tracie Hunte and Latif Nasser.

Rippin’ the Rainbow an Even Newer One

March 15, 2018 - 6:00pm

One of our most popular episodes of all time was our Colors episode, where we introduced you to a sea creature that could see a rainbow far beyond what humans can experience.

Peacock mantis shrimps are as extraordinary as they are strange and boast what may well be the most complicated visual system in the world. They each have 16 photoreceptors compared to our measly three. But recently researchers in Australia put the mantis shrimps’ eyes to the test only to discover that sure, they can SEE lots of colors, but that doesn't mean they can tell them apart.

In fact, when two colors are close together - like yellow and yellow-y green - they can’t seem to tell them apart at all.  

MORE ON COLORS: There was a time -- between the flickery black-and-white films of yore and the hi-def color-corrected movies we watch today -- when color was in flux. Check out this blog post on how colors made it to the big screen from our director of research, Latif Nasser. 

Our original episode was produced by Tim Howard and Pat Walters. This update was produced by Amanda Aronczyk.

Special thanks to Chris Martin of Creative Aquarium Nation, Phil Weissman, David Gebel and Kate Hinds for lending us their colorful garments. Also thanks to Michael Kerschner, Elisa Nikoloulias and the Young New Yorkers’ Chorus, as well as Chase Culpon and The Greene Space team.

Radiolab Presents: More Perfect - The Gun Show

February 23, 2018 - 6:00pm

The shooting in Parkland, Florida on February 14, 2018, reignited an increasingly familiar debate about guns in this country. Today, we’re re-releasing a More Perfect episode that aired just after the Las Vegas shooting last year that attempts to make sense of our country’s fraught relationship with the Second Amendment.

For nearly 200 years of our nation’s history, the Second Amendment was an all-but-forgotten rule about the importance of militias. But in the 1960s and 70s, a movement emerged — led by Black Panthers and a recently-repositioned NRA — that insisted owning a firearm was the right of each and every American. So began a constitutional debate that only the Supreme Court could solve. That didn’t happen until 2008, when a Washington, D.C. security guard named Dick Heller made a compelling case.

The Curious Case of the Russian Flash Mob at the West Palm Beach Cheesecake Factory

February 20, 2018 - 1:53am

We don’t do breaking news. But when Robert Mueller released his indictment a few days ago, alleging that 13 Russian nationals colluded to disrupt the 2016 elections, we had a lot of questions. Who are these Russian individuals sowing discord? And who are these Americans that were manipulated?? Join us as we follow a trail of likes and tweets that takes us from a Troll Factory to a Cheesecake Factory.

Smarty Plants

February 13, 2018 - 11:42pm

Do you really need a brain to sense the world around you? To remember? Or even learn? Well, it depends on who you ask. Jad and Robert, they are split on this one. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. Along with a home-inspection duo, a science writer, and some enterprising scientists at Princeton University, we dig into the work of evolutionary ecologist Monica Gagliano, who turns our brain-centered worldview on it’s head through a series of clever experiments that show plants doing things we never would've imagined. Can Robert get Jad to join the march?

Ghosts of Football Past

February 3, 2018 - 7:08pm

In anticipation of Super Bowl LII (Go Eagles), we're revisiting an old episode about the surprising history of how the game came to be. It's the end of the 19th century -- the Civil War is over, and the frontier is dead. And young college men are anxious. What great struggle will test their character? Then along comes a new craze: football. A brutally violent game where young men can show a stadium full of fans just what they're made of. Harvard, Yale, Princeton, Penn -- the sons of the most powerful men in the country are literally knocking themselves out to win these gladiatorial battles. And then the most American team of all, with the most to prove, gets in the game and owns it. The Carlisle Indian School, formed in 1879 to assimilate the children and grandchildren of the men who fought the final Plains Wars against the fathers and grandfathers of the Ivy Leaguers, starts challenging the best teams in the country. On the football field, Carlisle had a chance for a fair fight with high stakes -- a chance to earn respect, a chance to be winners, and a chance to go forward in a changing world that was destroying theirs.

Radiolab Presents: More Perfect - One Nation, Under Money

January 31, 2018 - 3:00am

An unassuming string of 16 words tucked into the Constitution grants Congress extensive power to make laws that impact the entire nation. The Commerce Clause has allowed Congress to intervene in all kinds of situations — from penalizing one man for growing too much wheat on his farm, to enforcing the end of racial segregation nationwide. That is, if the federal government can make an economic case for it. This seemingly all-powerful tool has the potential to unite the 50 states into one nation and protect the civil liberties of all. But it also challenges us to consider: when we make everything about money, what does it cost us?

The Voice in Your Head - A Tribute to Joe Frank

January 23, 2018 - 12:03am

How do you pay proper tribute to a legend that many people haven’t heard of?

We began asking ourselves this question last week when the visionary radio producer Joe Frank passed away, after a long struggle with colon cancer.  Joe Frank was the radio producer’s radio producer.  He told stories that were thrillingly weird, deeply mischievous (and sometimes head-spinningly confusing!). He had a big impact on us at Radiolab.  For Jad, his Joe Frank moment happened in 2002, while sitting at a mixing console in an AM radio studio waiting to read the weather.  Joe Frank's Peabody Award-winning series "Rent-A-Family” came on the air.

Time stood still.

We’ve since learned that many of our peers have had similar Joe Frank moments.

In this episode, we commemorate one of the greats with Brooke Gladstone from On the Media and Ira Glass from This American Life. 

This episode was produced by Jad Abumrad with help from Kelly Prime and Sarah Qari.

How to Be a Hero

January 9, 2018 - 6:09pm

What are people thinking when they risk their lives for someone else? Are they making complicated calculations of risk or diving in without a second thought? Is heroism an act of sympathy or empathy?  

A few years ago, we spoke with Walter F. Rutkowski about how the Carnegie Hero Fund selects its heroes, an honor the fund bestows upon ordinary people who have done extraordinary acts.

When some of these heroes were asked what they were thinking when they leapt into action, they replied: they didn’t think about it, they just went in.

Neuroscientist Robert Sapolsky says there is a certain kind of empathy that leads to action. But feeling the pain of another person deeply is not necessarily what makes a hero.  

Our original episode was reported and produced by Lynn Levy and Tim Howard. This update was produced by Amanda Aronczyk.
