The Boston Citgo sign, all 3,600 square LED feet of which has served as the backdrop to Red Sox games since 1965, is now officially a "pending landmark."

Spanish Surrealist Salvador Dalí spent much of the 1940s in the U.S., avoiding World War II and its aftermath. He was a well-known fixture on the art scene in Monterey, Calif. — and that's where the largest collection of Dalí's work on the West Coast is now open to the public.

The middle of summer is when the surprises in publishing turn up. I'm talking about those quietly commanding books that publishers tend to put out now, because fall and winter are focused on big books by established authors. Which brings us to The Dream Life of Astronauts, by Patrick Ryan, a very funny and touching collection of nine short stories that take place in the 1960s and '70s around Cape Canaveral, Fla.

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.

Solar Impulse 2 has landed in Cairo, completing the penultimate leg of its attempt to circumnavigate the globe using only the power of the sun.

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.

Attack By Chondrite: Scientists ID Russian Meteor

Feb 22, 2013

The meteor that caused at least 1,000 injuries in Russia after a startling and powerful daytime explosion one week ago has been identified as a chondrite. Russian scientists who analyzed fragments of the meteor, whose large size and well-documented impact made it a rarity, say that its composition makes it the most common type of meteor we encounter here on Earth.

"The fragments contain a standard number of minerals, including olivine, pyroxene, troilite and kamacite," scientist Viktor Grokhovsky of the Urals Federal University, told the Voice of Russia. "These minerals that can be discovered only in outer space confirm the fragments' extraterrestrial nature."

That means that before it shattered windows in the city of Chelyabinsk and turned people around the world into gawkers fascinated by a calamity — and by the amazing video footage of it — the meteor spent billions of years traveling through space.

When it detonated over Russia, the explosion was powerful enough to be "detected by 17 nuclear monitoring stations around the globe," as The Christian Science Monitor reports.

The meteor, which may have weighed as much as 10,000 tons and measured about 55 feet across, was traveling at an estimated 11 miles per second when it reached Earth, according to a report at io9.

"Chondrites are some of the most primitive rocks in the solar system," says Britain's Natural History Museum. "These 4.5-billion-year-old meteorites have not changed much from the asteroid they came from."

The museum says the meteor's name — pronounced with a hard "K" sound — comes from the Greek word for grains of sand.

But in the region where the meteor fell, the chondrite goes by another title: a chance to cash in. As NPR's David Greene tells Linda Wertheimer on Morning Edition, people have been scrambling to collect pieces of the famous meteor.

"A 16-year-old pulled one out of his pocket and said, 'Here's a piece of the meteor, right here," David says. "And this black market is developing. People have been coming to these villages and offering $100, $200 for little handfuls of space debris. The government's worried that people are going to be trying to sell it fraudulently. So, this whole new economic reality is developing around this stuff."
