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.

Kilograms With Weight Problems May Get High-Tech Cleanings

Jan 7, 2013

Back in 2009, as Morning Edition reported, some scientists were worried that the small metal cylinder used as the world's standard for what a kilogram should be might be losing weight.

But there were also those who thought the problem might have nothing to do with that carefully sealed away cylinder in Paris — that the real problem might be that the 40 replicas sent around the world are gaining weight.

The theory is that surface contamination is building up on the replicas, adding in some cases 50 or so micrograms to their weights compared to the original. They're kept in controlled conditions, of course, but get taken out more often than the original in Paris.

But you can't just clean them any old way. If a kilogram is going to be the same everywhere — an important thing for many scientific endeavors — the cleaning procedures have to be the same everywhere. And they have to do the job without scraping away any important material.

Well, as Wired reports, "scientists at Newcastle University have developed a high-tech way to clean the standards. ... It's based not on manually scrubbing the metal chunks but on exposing them to ultraviolet light and ozone about once per decade. Recently, [Newcastle's Peter] Cumpson fine-tuned the procedure and added another step: a pure water rinse to remove dust particles. The final recipe is now available online in the journal Metrologia."

Worrying about the replicas may some day seem quaint. As Wired has previously reported, scientists are also working on a way to craft a perfect kilogram out of silicon. To do it, though, they had to count the number of atoms in a kilogram of silicon — and then try to reproduce it. But even after two years of grinding and polishing, they still only reached "near perfection."

As for why any of this matters, Live Science notes that if "each country that has one of these standard masses has a slightly different definition of the kilogram, [that] could throw off science experiments that require very precise weight measurements or international trade in highly restricted items that are restricted by weight, such as radioactive materials."
