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.

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.

South Korea Vows Retaliation If Pyongyang Makes Good On Military Threat

Mar 6, 2013

South Korea upped the ante Wednesday after Pyongyang threatened to scrap the armistice that ended a brutal war between the rival neighbors in 1953, promising retaliation for any North Korean attack.

"If North Korea carries out provocations that threaten the lives and safety of South Koreans, our military will carry out strong and resolute retaliations," South Korea's Gen. Kim Yong-hyun told reporters in Seoul.

Kim's remarks came in direct response to a North Korean threat to attack South Korea and the United States if the two countries continue joint military exercises in the region that began March 1.

North Korea's Military Command announced Tuesday that it would "launch surgical strikes at any time and any target without being bounded by the armistice accord."

The two sides have remained technically at war for the past 60 years because the agreement in 1953 to end hostilities in the Korean War was a simple armistice and not a formal peace treaty.

But tensions have risen even further in the past year following a change in leadership in North Korea that ushered in Kim Jong Un, 30, to replace his late father, Kim Jong Il. Since then, Pyongyang has moved ahead with a series of provocative nuclear weapon and ballistic missile tests that have drawn international condemnation.

The U.S. has led the effort to clamp down on the North's nuclear ambitions, and on Tuesday, Washington introduced a U.N. Security Council resolution to target the North's cash transfers. China, which until recently has stood by longtime ally Pyongyang, has agreed to sign on to the new resolution. The resolution is expected to be formally adopted later this week.

Meanwhile, Reuters, quoting South Korea's Yonhap news agency, reports that the North appears to be preparing its own military exercises or a possible ballistic missile test:

"North Korea has set no-fly and no-sail zones off its east and west coasts that indicates it will conduct major military drills, but test firing of short-to-medium-range missiles cannot be ruled out, South Korea's Yonhap news agency, quoting South Korean government officials, said on Wednesday."
