While Mr. Krikalev was orbiting the earth, the Soviet Union disbanded, and he was asked to extend his stay by almost five months, in part because of his country’s disintegration and money problems in Moscow.He ended up staying in space for 313 days, returning to a home country that no longer existed.

Mr. Wilmore, who has a wife and two children, missed most of his younger daughter’s senior year of high school and his elder daughter’s sophomore year in college.

The astronauts were able to connect with friends, family and the public on the ground — they had access to email and video calls. They tried to put a positive spin on the whole experience.

“It’s work. It’s fun. It’s been trying at times, no doubt,” Mr. Wilmore said in an interview from the space station last week with The New York Times. “But ‘stranded’? No. ‘Stuck’? No. ‘Abandoned’? No.”

However, it has been NASA’s plan since August for the Crew-9 mission to return with Ms. Williams and Mr. Wilmore around this time frame.

President Trump suggested in January that the Biden administration had stranded the astronauts, and Elon Musk, the founder of SpaceX, said this month that the Biden administration had rejected his offer to bring them home sooner.But Bill Nelson, who served as the administrator of NASA during the Biden administration, said that NASA never heard about Mr. Musk’s offer, and that the agency’s decisions were based on what made the most sense for the operations of the space station.

But as with so many things in the early stages of the Trump administration, the astronauts’ return was tinged with politics.

After months of weightlessness, their bodies still adjusting to the pull of gravity, they were lifted onto gurneys.

On Tuesday, two NASA astronauts who had been in orbit since June, Suni Williams and Butch Wilmore, splashed down in calm, azure waters off the coast of the Florida Panhandle, concluding a saga that had captivated the country since last summer.

They set off to spend eight days at the space station. The trip lasted nine months.

Federal immigration officials did not immediately reply to questions about Mr. Khalil’s transfer, including why he was taken more than 1,000 miles from his home in New York City.

Mr. Khalil is of Palestinian heritage and graduated in December from Columbia with a master’s degree

A group of faculty members from Columbia prepared to gather Monday evening with Jewish community leaders and immigrant rights advocates to denounce what they described as “the unprecedented and unconstitutional arrest of a permanent resident and Columbia graduate student in retaliation for his political activity.”

He is married to an American citizen who is eight months pregnant, his lawyer said.

President Trump hailed the arrest of Mr. Khalil in a Truth Social posting on Monday and pledged that more student arrests are forthcoming.

His lawyer, Amy Greer, said after his arrest that he was a green card holder and that the detention would be challenged.

Along with the suspended military aid, the Trump administration also paused sharing intelligence with Ukraine, the C.I.A.’s director, John Ratcliffe, said in an interview with Fox Business News on Wednesday.

“You’re always going to have to pick and choose — you aren’t going to be able to defend against everything,”

Each Patriot system — consisting of interceptor missiles, launchers, radar and a command center — can cost $1 billion and takes up to two years to build.

“of course, our military, the government, have the capabilities, the tools to maintain the situation on the front line.”

And industry executives say they cannot invest in those improvements without the guarantee of contracts that generally run for at least a decade, and that some governments have been unwilling to provide.

But manufacturers of more advanced weapons like the air defenses Ukraine says are crucial to its survival are still struggling to quickly produce those systems in large numbers.

Artillery production in Europe is now nearly able to keep up with the wartime demands, said Camille Grand, who was NATO’s assistant secretary general for defense investment when Russia invaded.

“But the 20 percent is the most lethal and important,”

“Ukraine definitely has a safety margin of about six months even without systematic assistance from the United States, but it will be much more difficult, of course,”

“Europe can’t possibly replace American aid,” the former deputy of Ukraine’s military general staff, Lt. Gen. Ihor Romanenko, said last month.

Despite Europe’s pledges of unwavering support for Ukraine, which have only intensified since the Trump administration began pulling back, it would be nearly impossible for it to fill the weapons gap quickly.

The United States had committed to delivering as much as $11 billion in weapons and equipment to Ukraine this year. Some of it was from Pentagon stockpiles, while some was ordered through new defense contracts, according to a new analysis by the Center for Strategic and International Studies in Washington.

In addition, he said that women are more likely than men to socialize, protecting them from the detrimental effects of social isolation and loneliness.

Scientists haven’t yet examined this in humans, but Dr. Dubal said the fact that we have the same hormones and sex chromosomes, and similar reproductive systems, suggests that the findings could be similar in people.

It may seem counterintuitive that elevating other nicotine products can save lives. But that may be what we need to finally end the harms caused by smoking.

Nicotine does increase heart rate,

Some 15 percent of Swedes use an oral tobacco product called snus daily

Data from Sweden suggests that if other nicotine delivery systems, such as appropriately regulated oral pouches, pose any cancer risk, it is small compared with the dangers of cigarette smoke.

More than half of all long-term smokers will die a smoking-related death.

Regulators may need to accept that wider access to vaping could mean more young people use these products. But if vaping continues to displace smoking rather than fuel it, that trade-off could ultimately be a public health win.

Their concerns intensified as vaping among teenagers surged, peaking in 2019 when more than a quarter of 12th graders reported using vapes in the past month

What Americans really need is access to safer products.

At the same time, regulators fear that the very products that help smokers quit — such as vapes or oral nicotine pouches — also attract young people.

If they make cigarettes less satisfying without offering appealing alternatives, smokers who can’t quit may turn to illicit markets.

Toward the end of the set, he pulled out a banner combining the flags of Palestine and Sudan that featured a heart and a fist. Was this part of the performance, another level of commentary woven into a show already packed with it?

Lamar is perhaps the most sober of all of hip-hop’s contemporary greats, a ferocious storyteller who values tongue-tripping polemics and introspection; he is not exactly a beacon of joy.

What will remain is his grin when he finally began rapping that song. It was wide, persistent, almost cartoonish in shape. The grin of a man having the time of his life at the expense of an enemy.

In the lead-up to Kendrick Lamar’s headline performance at the Super Bowl LIX halftime show on Sunday night, most of the chatter focused on whether he would play the song that was effectively the knockout blow in his monthslong battle with Drake last year. The song that became Lamar’s signature hit, and a generational anthem. The song that won both record and song of the year at the Grammys just a week ago. The song that appeared to recalibrate hip-hop’s power rankings, perhaps permanently.

On Sunday in New Orleans, Kendrick Lamar became the first solo rapper

He threatened tariffs on Colombia for refusing to accept U.S. military flights of deported migrants, and Colombia quickly backed down.

“He thrives in chaos, he thrives in uncertainty,” John Feeley, the former U.S. ambassador to Panama and deputy chief of mission in Mexico, said of Mr. Trump.

Drug fatalities in the United States declined last year after years of unrelenting overdose spikes.

Mexico had already ramped up border enforcement before Mr. Trump’s tariff threat, and illegal crossings have plummeted.

“I’d like to see Canada become our 51st state.”

“I don’t know.”

He has been far less clear about what, exactly, those demands are — a strategy that allows him to declare victory when he sees fit.

“A man’s assertion that he is a woman, and his requirement that others honor this falsehood, is not consistent with the humility and selflessness required of a service member,” the order added.

But the new guidance related to gender went much further by authorizing the Defense Department to potentially bar transgender soldiers by considering identifying as a gender other than the one assigned at birth an impediment to the physical and mental well-being necessary for military service.

but that the publisher did so while knowing that the information was false or with substantial doubts about its accuracy.

The following week, Lamar will headline the Super Bowl halftime show in New Orleans.

On one track, “Family Matters,” Drake questioned whether Lamar’s manager had secretly fathered one of his children and alleged that Lamar had “beat on” his romantic partner and covered it up.

In November, Drake had initiated pre-litigation actions against Universal in state court in New York and Texas, naming Spotify and the radio conglomerate iHeartMedia as potential participants in an elaborate scheme to promote “Not Like Us” using bots and payola.
