The morning after a gunman targeted and killed five law enforcement officers, Dallas Mayor Mike Rawlings called it "ironic" that his city was the target of the worst police loss-of-life since the terrorist attacks on Sept. 11, 2001.

This summer, NPR is getting crafty in the kitchen. As part of Weekend Edition's Do Try This At Home series, top chefs are sharing their cleverest hacks and tips — taking expensive, exhausting or intimidating recipes and tweaking them to work in any home kitchen.

First up: making magically moist sous vide chicken without the fancy equipment.

Derek Lucas Reyes, 20, went from being undocumented in the U.S. to undocumented in his native Mexico.

He sits at a table after breakfast in a shelter filled with people recently deported from the U.S. to Nogales, Sonora. At his feet is a paper shopping bag the Department of Homeland Security gave him for his belongings. Inside the bag: his deportation paperwork, a toothbrush, toothpaste and some other necessities he got from Mexican aid workers.

Millions of gallons of water used to flow every day from the Rocky Mountains to the Gulf of California. Now, the Colorado River ends at Morelos Dam on the U.S.-Mexico border. Below it, one of North America's largest wetlands is dry.

Karl Flessa, a geoscientist at the University of Arizona, began researching the damage two decades ago. Then he started asking how much water it would take to bring back some of the habitats.

Border Patrol checkpoints aren't always near the border. Some aren't even on roads that go to the border. Take Arivaca Road; it's an East-West route 25 miles north of the Mexican border in Southern Arizona.

A Border Patrol checkpoint has been operating there around the clock for seven years. Some residents of the town of Arivaca say agents at the checkpoint go well beyond their legal authority; searching vehicles and questioning citizens without cause. So they've begun their own monitoring — to inspect the process.

Let's say you're skiing in the backcountry, looking for some powder — but instead, you trigger an avalanche.

If you have an avalanche air bag pack strapped to your back, you just yank the cord. That deploys the air bag, which keeps you close to the surface and easier to dig out, says Andy Wenberg with Backcountry Access, one of several companies making the devices. When deployed, his company's version of the air bag comes out like wings.

"The whole idea when you deploy that thing in an avalanche is you're avoiding burial death," he says.

Freestyle aerial skier Mac Bohonnon recently finished second at the Val St. Come World Cup in Quebec, and that helped him qualify for the Olympics in Sochi. But when he's not doing triple-twisting double backflips, he's taking Advanced Placement classes at Team Academy in Park City, Utah.

As the U.S. government has militarized the California and Arizona segment of the Southwest border over the last two decades, illegal crossers have moved to another area. South Texas has become the new border hot spot.

The Rio Grande Valley is also the closest route to Central America. Two-thirds of those caught crossing are from that troubled region.

The Border Patrol and local authorities are straining to keep up.

Fleeing Poverty And Murder

A years-in-the-making, top-secret engineering and design project for a superaerodynamic suit to be worn by U.S. speedskaters at next month's Winter Olympics was finally unveiled Thursday.

Defense contractor Lockheed Martin and sporting goods company Under Armour released photos of the suit they're calling "Mach 39." It has been kept so tightly under wraps that the sport's governing body wouldn't even allow it to be worn at the Olympic trials in Salt Lake City.

A relic of the Cold War met its end on Thursday. The Air Force destroyed the last B-52 bomber required under the New Strategic Arms Reduction Treaty with Russia.

A crew used a circular saw to cut through the plane's aluminum skin, the tail section separating from the fuselage with a loud thunk and officially rendering the bomber useless.

Imagine your city council telling the police department how many people it had to keep in jail each night.

That's effectively what Congress has told U.S. Immigration and Customs Enforcement with a policy known as the "detention bed mandate." The mandate calls for filling 34,000 beds in some 250 facilities across the country, per day, with immigrant detainees.

JPMorgan Chase says it will cover Social Security and Welfare payments for its customers if the government goes into default or the shutdown continues.

If nothing else, it's good public relations for a company which hasn't had much lately.

The bank spent nearly 40 percent of the company's revenue over the last quarter — more than $9 billion — on legal expenses. Money paid to fight government investigations and on fines.

It's chile season in New Mexico, where they take their chiles pretty seriously.

Indeed, the chile is the official state vegetable, so it's probably best to not mention it is actually a fruit. No matter what it is, the fall harvest is on, and that means it's time to fire up the grills.

Green chiles roasting over a hot gas flame give off a smoky, sweet, pungent perfume.

That smell is part of what has drawn customers like Lorenzo and Peggy Lucero to the Diaz farm in Deming, in southwest New Mexico, for the past 30 years.

These days, the Federal Public Defender's Office in Tucson, Ariz., has lots of space. Since the federal budget cuts known as sequestration began, the office has lost a quarter of its staff to layoffs or furloughs.

Under the Constitution, clients still need legal representation, so judges have to appoint private attorneys to replace the public defenders.

The sequester was supposed to save money. But in this case, the sequester is costing federal dollars.

If you like mysteries, thrillers or zombie flicks, you'll probably like Abigail Goldman's art.

Goldman takes the fake grass, dirt and tiny plastic people used in model railroad layouts, and turns them into imaginary crime scenes. She's been making the macabre art for four years, and it's become so popular there's a waiting list for her work.

The Arizona Legislature is debating whether to extend Medicaid to about 300,000 people in the state. The expansion is a requirement to get federal funding under the Affordable Care Act.

The big surprise is who has been leading the charge: Republican Gov. Jan Brewer. She's one of President Obama's staunchest critics and has confounded conservatives in her own party by supporting the expansion.

Google the words "Brewer" and "Obama." You'll get a now-famous image of Brewer wagging her finger at the president on the tarmac last year when she met him in Phoenix.
