When the United Kingdom voted to leave the European Union last month, the seaside town of Port Talbot in Wales eagerly went along with the move. Brexit was approved by some 57 percent of the town's residents.

Now some of them are wondering if they made the wrong decision.

The June 23 Brexit vote has raised questions about the fate of the troubled Port Talbot Works, Britain's largest surviving steel plant — a huge, steam-belching facility that has long been the town's biggest employer.

Alabama authorities say a home burglary suspect has died after police used a stun gun on the man.  Birmingham police say he resisted officers who found him in a house wrapped in what looked like material from the air conditioner duct work.  The Lewisburg Road homeowner called police Tuesday about glass breaking and someone yelling and growling in his basement.  Police reportedly entered the dwelling and used a stun gun several times on a white suspect before handcuffing him.  Investigators say the man was "extremely irritated" throughout and didn't obey verbal commands.

It wasn't his lovably disheveled wardrobe, or his Elvis ring, but something else: the force of his flamboyant personality. Margolis, a graduate of Harvard Law School, didn't want to fit in with the crowd. He wanted to stand out.

A police officer is free on bond after being arrested following a rash of road-sign thefts in southeast Alabama.  Brantley Police Chief Titus Averett says officer Jeremy Ray Walker of Glenwood is on paid leave following his arrest in Pike County.  The 30-year-old Walker is charged with receiving stolen property.  Lt. Troy Johnson of the Pike County Sheriff's Office says an investigation began after someone reported that Walker was selling road signs from Crenshaw County.  Investigators contacted the county engineer and learned signs had been reported stolen from several roads.

Can Shellfish Adapt to More Acidic Water?

LINDA WERTHEIMER, HOST:

The shellfish industry on the West Coast has had a bumpy few years and increasingly, it is pointing to climate change as the cause. Scientists believe the oceans are becoming more acidic as they absorb the increasing amounts of carbon dioxide in the air, and they are not sure if oysters and other shellfish will be able to adapt to this change. Lauren Sommer, from member station KQED, has this report.

LAUREN SOMMER, BYLINE: Terry Sawyer does a brisk business in oysters.

TERRY SAWYER: I take the shucking knife and I'll go into the hinge. You see there's no meat on the top shell?

SOMMER: His farm, Hog Island Oyster Company, is about an hour north of San Francisco and today, his workers are sorting two kinds of oysters, Kumamotos...

SAWYER: Nutty, creamy flavor...

SOMMER: And Sweetwaters.

SAWYER: Some people do describe it as sweeter.

SOMMER: The oysters grow up in big mesh bags that sit in the cold waters of the Pacific. Sawyer gets the oysters from hatcheries in Oregon and Washington, but a few years ago, he started getting calls from his suppliers. They couldn't fill the orders.

SAWYER: They would have tens of thousands of gallons of tanks that were absolutely full of larvae and they'd had the entire system die.

SOMMER: Their intake pipes were pulling in the same sea water, but now it was more acidic, which makes it harder for oysters to build their shells. The ocean is basically a giant sponge for carbon dioxide and scientists say sea water has become 30 percent more acidic since the start of the Industrial Revolution. Sawyer's growing his own oyster larvae now so he'll have a more predictable supply, but he says there's no question that climate change is affecting his bottom line.

SAWYER: We don't know if we're going to be able to survive the very real trending that is going on out there.

SOMMER: It's a trend that doesn't just affect oysters. On a rocky point farther point, about two hours from San Francisco, oceanographer Tessa Hill of the University of California, Davis shows me tide pools packed with California mussels. These mussels and other shelled animals like sea urchins and tiny marine snails are crucial to the marine food web, she says.

TESSA HILL: Probably most people like the fact that we have things like whales and salmon along our coast and those organisms are likely to be impacted because their food source will be impacted.

SOMMER: In 100 years, oceans could be more than twice as acidic. So, Hill says, they're trying to find out if marine life can adapt. The mussels and sea urchins here could help answer that, since they're already part of a naturally occurring experiment.

HILL: They're facing the most acidic water that you'd see in the ocean today.

SOMMER: Marine life on the West Coast is blasted with acidic water from the deep ocean during seasonal upwelling in the spring and summer. So maybe they've developed ways to handle it.

HILL: SB would be Santa Barbara; MB is Monterey Bay...

SOMMER: Inside their lab, Hill shows me jars full of young mussels almost too small to see. Each jar is from a different part of the West Coast, from central Oregon to southern California. Scientists are growing them in more acidic water to see if they have key genetic differences.

STEVE PALUMBI: We found they have lucky genes.

SOMMER: Steve Palumbi is a biology professor at Stanford University who is also working on the project. He found that some West Coast sea urchins have around 100 genes that make them better adapted to more acidic water. That makes them more likely to survive and reproduce.

PALUMBI: This is good news because these organisms have the capacity to deal with more acidification. But it's not good news forever, because all it does is give us a little breathing room.

SOMMER: And not much breathing at that, says Palumbi. The ocean is acidifying faster than it ever has before. Organisms will evolve, he says, but probably not fast enough to keep up. That means the shellfish industry could face even bigger challenges down the road. For NPR News, I'm Lauren Sommer in San Francisco. Transcript provided by NPR, Copyright NPR.
