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 can be hard to distinguish among the men wearing grey suits and regulation haircuts on Pennsylvania Avenue in Washington. But David Margolis always brought a splash of color.

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.

Montgomery Education Foundation's Brain Forest Summer Learning Academy was spotlighted Wednesday at Carver High School.  The academic-enrichment program is for rising 4th, 5th, and 6th graders in the Montgomery Public School system.  Community Program Director Dillion Nettles, says the program aims to prevent learning loss during summer months.  To find out how your child can participate in next summer's program visit Montgomery-ed.org

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.

Buzz Off: Bedbugs Unfazed By Ultrasonic Devices

With bedbugs bunking just about everywhere these days, people battling the bloodsucking insects may be tempted to try their hand at driving them away.

But ultrasonic bug zappers, which retail for less than $25, aren't the solution, say entomologists who tested some of the devices.

"I can understand on a personal level how you would want to go to great lengths and get rid of them and protect yourself," says Kasey Yturralde, a grad student in entomology at Northern Arizona University. She had a memorable trip back in 2006 when she ran into them while visiting a friend. "It was pretty traumatic," she tells Shots.

Recently, Yturralde and her co-author Richard W. Hofstetter tried out four different ultrasonic devices available on Amazon: one designed specifically for bedbugs and three that claimed to repel insects and small furry mammalian pests.

Their simple experimental design consisted of two 5-gallon buckets lined with sound-muffling insulation that were connected by a tube. An ultrasonic device was placed in one bucket, and eight to 10 bedbugs were placed in the tube.

More care was given to how the bedbugs were housed in the lab. The researchers kept them in large jars, like those used for canning, which were placed in bins full of soapy water. And every lip or edge over which an rogue bedbug would have to crawl was covered in a slippery substance a little like liquid Teflon, Yturralde says, to keep them from escaping.

In test after test, the bedbugs showed no preference for either bucket. "They were equally distributed across the two arenas," Yturralde notes. None of the four devices drove the bedbugs away.

It wasn't entirely illogical to think that ultrasonic frequencies might work against bedbugs. After all, the bark beetles Yturralde and Hofstetter normally study communicate in the ultrasonic range of sound. The devices could interfere with bug communication. But, of course, not all bugs act the same.

"There have been tests of these devices with other insects, and they haven't shown any effect," Yturralde says. Now people can know that they won't be effective on bedbugs either, she says, "and move onto other means of extermination."

The results appear in the Journal of Economic Entomology.
