Three days after the U.K. said it was expelling 23 Russian diplomats over the poisoning of a former Russian double agent on U.K. soil, Russia says it's responding in kind, by kicking out 23 U.K. diplomats currently in Moscow.

The Russian Ministry of Foreign Affairs said in a statement Saturday that 23 British diplomats are "persona non grata" and must leave the country within a week.

A researcher at the Massachusetts Institute of Technology says he is revising a study he co-authored after admitting that "criticism is valid" of initial findings that Uber and Lyft drivers are making a median pretax profit of $3.37 an hour and a vast majority are making less than minimum wage.

Uber said the working paper had "a major error in the authors' methodology."

Would your dog remember you after 10 years away?

Carly Suierveld thinks so. She just saw her dog Abby for the first time in a decade.

"It's quite a journey, it was so great seeing her again," Suierveld tells NPR's Scott Simon. "She barked at me at first, but now she's cuddling up and kind of seeming to remember who I am."

Abby, a female black Lab mix, was lost from the Suierveld family's home in Apollo, Pa., 10 years ago. Carly was 12 at the time.

Editor's note: Following sharp criticism of how this MIT study was conducted, its authors say they will redo their analysis. Uber chief economist Jonathan Hall gives his assessment of the "inconsistent logic" leading to an undercount of hourly earnings and "a major error" in the conclusions in this post.

The White House says it "could have done better" in its handling of allegations of domestic abuse against former staff secretary Rob Porter.

Principal deputy press secretary Raj Shah on Thursday called the allegations "troubling" and insisted White House officials took them seriously while suggesting that any missteps in their response were because the "emerging reports were not reflective of the individual who we had come to know."

A lot of people watch the Super Bowl every year.

You know that. Last year about 111 million people watched. The game three years ago became the most-viewed ever, with 114 million people watching.

But football ratings overall have dropped in the past couple years. Numbers for the 2017 season were down 9.7 percent, continuing a decline from the year before.

To be clear, the audience for football is still enormous and dwarfs almost everything else on TV.

At least two people were killed and at least 100 people were injured early Sunday morning when an Amtrak train derailed after colliding with a freight train in South Carolina.

The derailment happened in Cayce, outside of South Carolina's capital of Columbia.

Humans have wanted to go to Mars for a long time. NASA says it wants to send people there by the 2030s, while private companies like SpaceX have proposed building colonies on the Red Planet.

There are, of course, a lot of kinks that have to be worked out for us to get there. One of them is living in an enclosed space with a few other people for months on end.

The Department of Homeland Security says it will once again accept renewal requests from recipients of the Deferred Action for Childhood Arrivals program in response to a court order.

"Until further notice, and unless otherwise provided in this guidance, the DACA policy will be operated on the terms in place before it was rescinded on Sept. 5, 2017," U.S. Citizenship and Immigration Services, a part of DHS, wrote on its website Saturday.

Dozens of new emojis are planned for 2018.

One of the most popular additions? Redheads.

"People felt like they were getting left out," says Jeremy Burge of the Unicode Emoji Subcommittee. It's part of the Unicode Consortium, which sets the international standards for emojis, among other things.

"Even though I don't have red hair myself, that was the number one request we got for the last two years running. So I felt like I should step up and try and make that happen," Burge tells NPR's Weekend All Things Considered.
