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.

President Obama is challenging Americans to have an honest and open-hearted conversation about race and law enforcement. But even as he sits down at the White House with police and civil rights activists, Obama is mindful of the limits of that approach.

"I've seen how inadequate words can be in bringing about lasting change," the president said Tuesday at a memorial service for five law officers killed last week in Dallas. "I've seen how inadequate my own words have been."

Mice watching Orson Welles movies may help scientists explain human consciousness.

At least that's one premise of the Allen Brain Observatory, which launched Wednesday and lets anyone with an Internet connection study a mouse brain as it responds to visual information.

The FBI says it is giving up on the D.B. Cooper investigation, 45 years after the mysterious hijacker parachuted into the night with $200,000 in a briefcase, becoming an instant folk figure.

"Following one of the longest and most exhaustive investigations in our history," the FBI's Ayn Dietrich-Williams said in a statement, "the FBI redirected resources allocated to the D.B. Cooper case in order to focus on other investigative priorities."

This is the first in a series of essays concerning our collective future. The goal is to bring forth some of the main issues humanity faces today, as we move forward to uncertain times. In an effort to be as thorough as possible, we will consider two kinds of threats: those due to natural disasters and those that are man-made. The idea is to expose some of the dangers and possible mechanisms that have been proposed to deal with these issues. My intention is not to offer a detailed analysis for each threat — but to invite reflection and, hopefully, action.

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.

How A Superbug Traveled The World

Dec 10, 2012

Just as the name implies, Clostridium difficile is a difficult pathogen to beat. It causes a nasty infection in your gut, and it's often resistant to many antibiotics.

But C. difficile got even more troublesome about 10 years ago when a particularly virulent form of the bug cropped up in hospitals across the U.S and was no longer vulnerable to one of the most common classes of antibiotics.

These days antibiotic-resistant C. difficile is a superbug that kills nearly 14,000 Americans a year.

British geneticists just sequenced a bunch of these C. difficile strains from around the world. And, the genomic data chart how the drug-resistant bacteria arose in North America and then hopped to Europe, Australia and Asia.

The findings were just published in the journal Nature Genetics.

C. difficile infections usually occur in hospitals when patients have been treated with large doses of antibiotics. So Trevor Lawley and his team at the Wellcome Trust Sanger Institute sequenced the genomes of 151 C. difficile strains isolated from hospital patients between 1985 and 2010.

From the DNA sequences, they calculated that the highly virulent form of C. difficile first appeared in Pittsburgh around 2001. From there, it spread to Oregon, New Jersey, Arizona and Maryland, where it caused major hospital outbreaks in each state. Since 2007, the drug-resistant bacteria have also made appearances in South Korea and Switzerland.

The genomic data also showed that another superbug of C. difficile cropped up independently in the U.S. around the same time. The scientists can't pinpoint exactly where it originated, but they know it spread to Montreal in 2003 and the Netherlands in 2006.

This strain found its way to the U.K. on four separate occasions, likely triggering a large hospital outbreak that reached both London and Cambridge.

Lawley and his team also figured out how the superbugs picked up resistance to a common class of antibiotics called fluoroquinolones that includes such drugs as Levaquin and Cipro.

Both strains independently acquired a single mutation in an enzyme that binds fluroquinolones, and the strains also captured genes that pump antibiotics out of their cells.

American doctors heavily prescribed fluoroquinolones in the late 1990s and early 2000s. And, Lawley thinks this study is a cautionary tale about the risk of overusing antibiotics.

"The data indicated that antibiotic resistance can happen more frequently than we appreciated," Lawley tells Shots. "And, it will probably happen again."
