CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting.

Scientists get a rare peek inside of an exploding star

Telescopes on Earth and in space — including Hubble — have teamed up to study the unique explosion of high-energy radiation first observed in July. Astronomers reported Tuesday it’s unlike anything they’ve witnessed before.

The repeated bursts of gamma rays were detected over the course of a day, according to scientists. That’s highly unusual since these kinds of bursts normally last just minutes or even milliseconds — rarely no more than a few hours — as dying stars collapse or are torn apart by black holes.

Scientists said such a long and recurrent gamma ray explosion is puzzling — a cosmic whodunit, at least for now. More observations are needed to confirm its precise whereabouts.

The European-led team announced its findings in the Astrophysical Journal Letters in August.

St. Paul officer’s wife manages flowers for Backing the Blue Line. Now they’re readying roses for her husband.

posted in: All news | 0

The wife of a St. Paul police officer who died unexpectedly last week is a volunteer who has led efforts to provide blue memorial roses at law enforcement funerals.

Now, people are rallying around Shanna McArthur and a fundraiser has been established for her.

Officer Eric McArthur, 45, passed away at his Burnsville home early Friday of suspected cardiac arrest. He was “a loved husband, caring dad and a courageous officer and veteran,” Gretchen Gifford, a friend of Shanna McArthur’s, wrote on social media Monday night.

“It’s not fair that he was taken from his family at such a young age and with kids who are so young and deserve to have their dad watch them run in cross country meets, march in the high school band and dance in ballets!” Gifford continued.

Shanna McArthur is memorial rose director for Backing the Blue Line, a Minnesota nonprofit that supports law enforcement officers’ spouses and significant others. They prepare and distribute blue memorial roses for funerals and provide ongoing support for families.

When a gunman killed Burnsville firefighter/paramedic Adam Finseth and Burnsville officers Matthew Ruge and Paul Elmstrand in February 2024, police officers’ wives from around Minnesota readied 4,000 roses for the memorial service. The effort was about more than the roses, which they handed out to people in attendance at the service.

They wanted the recipients to know: “We’re thinking about them. We’re there with them. We support them,” Shanna McArthur said at the time.

Gifford, president of Backing the Blue Line, said they will be preparing blue roses for Eric McArthur’s funeral.

Eric McArthur, a father of two, “worked hard to support their family as a K-9 officer for the city of St. Paul and the loss of his income will put some financial strain on Shanna and the kids,” which is the reason for the online fundraiser, which can be found at btbl.info/McArthurFundraiser, Gifford wrote. He and Shanna were married for 18 years.

Gifford said Shanna McArthur is “one of the most giving and kind people I have ever met. … I don’t know if she knows the word ‘no’ or the phrase ‘I can’t this time.’”

McArthur was previously a police and fire dispatcher for the Bloomington Police Department. He joined the St. Paul Police Department nearly 10 years ago and was with the K-9 unit since 2021, serving with his K-9 partner Finn. He was also on the department’s honor guard and peer support team.

He served 20 years in the Army National Guard and deployed three times to Afghanistan, Iraq and Kuwait. He earned the Bronze Star.

“Eric will be remembered for his bravery, his compassion, and the quiet strength he brought to every part of his life,” his obituary said. “His legacy lives on in those he protected, served, and loved – especially in Caleb and Lila, who were his heart and his greatest pride.”

Visitation will be 3-7 p.m. Saturday at O’Halloran & Murphy Funeral Home, 575 S. Snelling Ave., St. Paul. A memorial service will be 4 p.m. Sunday at Hosanna Church, 9600 163rd St W., Lakeville.

Chicagoans change routines as immigration crackdown looms. Some carry passports and avoid stores

CHICAGO (AP) — The streets in some of Chicago’s liveliest neighborhoods are quiet these days. Public schoolteachers want online learning for families scared to venture out. And houses of worship are urging people to carry identification everywhere they go.

As the nation’s third-largest city awaits a much-hyped federal intervention, residents are making changes in their daily routines. President Donald Trump has promised Chicago will see a surge in deportations and National Guard troops as he targets Democratic strongholds. While the feeling of being vulnerable isn’t new, especially among immigrants, many say this time the fear is deeper and the preparations more drastic.

Even Sam Sanchez, a Chicago restaurant owner who voted for Trump, criticized the Republican’s plans for the city. As a naturalized U.S. citizen from Mexico, he is also taking precautions.

“They’re profiling,” he said of federal agents. “My wife and I went to a wedding and I told my wife, ‘Bring your citizenship papers.’ ”

Slower business traffic

There is a noticeable drop in street food vendors in Chicago’s Little Village neighborhood, and businesses report less foot traffic. The largely Mexican enclave features a two-mile stretch of businesses and restaurants that is often noted as one of Chicago’s highest-grossing shopping districts after Michigan Avenue.

“The streets that were busy are dying down,” said Galila Mendez, 25, who visits from the suburbs.

The neighborhood has been subject to immigration enforcement before.

Residents are quick to recall a 2007 daytime raid that locked down a popular shopping mall and increased enforcement in 2019 during Trump’s first term. Another wave of trepidation came in January when the Trump administration launched a nationwide operation from Chicago.

But things feel more intense now.

Xochitl Martinez, who has sold clothes in the area for about 20 years, said that since Trump’s second term, the streets are “dead.”

“If Trump wants to be intelligent, he has to support Latinos so we can work, so stores can open, so more sales can happen, so we can prosper more and lift up our families and lift up the country,” Martinez said.

Celebrations for Mexican Independence Day, which Chicago commemorates for weeks with car caravans, parades and festivals, have been muted. One festival was canceled while others added security.

Immigration attorneys say their clients are afraid to attend appointments, including at court. Churches with large immigrant populations are starting to notice an attendance dip.

Fabio Fernandez, owner of 3W-We Will Win, an art and T-shirt company in the predominantly Latino Pilsen neighborhood, said a mood of anxiety and uncertainty permeates. He has seen fewer customers.

“We shouldn’t fear or feel like we can’t walk the same streets that we usually roam,” he said.

Recent arrests

Fueling Chicagoans’ fear is the lack of information about what the Trump administration plans to do.

Calls to an activists’ emergency hotline to report immigration arrests have jumped in recent days, including details that couldn’t be confirmed or were mistaken.

“The deportation machine has always existed for decades,” said Antonio Gutierrez with Organized Communities Against Deportations. “This feels unprecedented.”

A handful of weekend immigration arrests launched the city’s vocal immigrant rights groups into action. Activists said five people in a predominantly Latino area, including a longtime flower vendor, were targeted by armed and masked federal agents.

Federal officials said the arrests were part of ongoing U.S. Immigration and Customs Enforcement activity and resulted in the detention of four people with previous criminal arrests. The arrests came a day before the Department of Homeland Security announced a new operation in Chicago because of its so-called sanctuary laws, which limit cooperation between local police and federal agents.

It was unclear what role the operation would play in the broader threats of federal intervention, but activists and elected officials said it felt like things were ramping up.

“They’re gathering steam,” Illinois Gov. JB Pritzker said Tuesday.

Pritzker and Chicago Mayor Brandon Johnson object to any federal surge and have promised to sue.

Some Chicagoans carry passports

Attorneys and activists have encouraged immigrants to carry documents and share their whereabouts for months. The message has spread recently to U.S. citizens and in Black and LGBTQ enclaves.

Vianney Alarcon, 42, says she has started carrying her passport when she leaves her North Side home. Her parents keep their green cards with them.

“It’s just disheartening,” she said.

Roughly 20% of Chicago’s 2.7 million people are foreign born. Most come from Mexico, China and India, according to Census estimates. Racially, white, Black and Latino residents each comprise roughly one-third of the city, with a smaller number of Asian residents.

A group of pastors, imams and rabbis urged all residents this week to carry identification, film encounters and protest. The guidance comes after the U.S. Supreme Court lifted a restraining order barring immigration authorities in Los Angeles from stopping people solely based on things including race.

“We will fight for this city,” said the Rev. Otis Moss III of Trinity United Church of Christ, the influential Black church once attended by former President Barack Obama.

Teachers want online learning

Despite the widespread unpopularity of remote learning, the Chicago Teachers Union wants schools to offer it for students who fear being targeted by immigration agents.

Union President Stacy Davis Gates said Chicago should follow Los Angeles’ lead; the city’s schools offered offering online options amid an immigration crackdown earlier this year.

“Because they had the infrastructure for online learning they were able to direct young people to those spaces,” she said.

Chicago Public Schools leaders said the district will continue classes in person, but they will reassess as needed.

“In-person instruction continues to provide the strongest foundation for learning,” officials said.

In letters to parents, district officials have reiterated that schools don’t coordinate with U.S. Immigration and Customs Enforcement or ask for immigration status. School leaders noted that children who felt unsafe walking home could duck into a church or firehouse and create neighborhood text groups.

Teachers in the district that is predominantly Black and Latino have been passing out flyers informing families of their rights.

“We know that being informed is the best way to empower our communities to stay safe,” said Linda Perales, a special education teacher.

Associated Press writers Melina Walling and Laura Bargfeld in Chicago contributed.

Rio 1854, from family behind Taco Libre, coming to former Dock spot in Stillwater

posted in: All news | 0

Rio 1854, a new restaurant from the family behind local mini-chain Taco Libre, is set to open next month in the former site of The Dock in downtown Stillwater.

The menu at the full-service restaurant — open for breakfast, lunch and dinner — will showcase Latin American flavors in a vibrant and colorful space, said Anthony Ramirez, who along with his two sisters and parents are behind the project. Think seafood, grilled meats or parrilladas, and fun cocktails and non-alcoholic beverages.

“We’ve been really interested in a full sit-down restaurant; we were just looking for the perfect location — and I think we found it,” he said. “We try to give a little bit of everything to the people.”

The Ramirez family also owns Mexatlan Supermercado in South St. Paul in addition to Taco Libre, which initially opened in West St. Paul and has locations in Eagan, Oakdale, Roseville and Edina.

The Dock, previously known as The Dock Cafe, closed in February. It had previously been closed from early 2020 till 2022, when it reopened under new management and with a new menu.

In addition to a large parking lot, there’s also a patio overlooking the St. Croix River with an outdoor bar, Ramirez said. When the weather is nice, Rio 1854 is planning to host live music on the patio, and on chillier days, there’ll be bonfires and “igloos” — those heated domes that enclose individual tables — so outdoor dining can continue.

The Ramirez family has spent the past few months preparing the space and redecorating — no major structural changes, but updating the decor and vibe for the new restaurant concept.

“It’s not an upscale restaurant, though the food quality will taste like it,” Ramirez said. “It won’t be a reservations-only kind of place. We’re keeping it affordable to everybody.”

Rio 1854 is set to open sometime in October, Ramirez said. Tentative hours are from 7 a.m. to 9 or 10 p.m.
