A United Nations agency that monitors and defends human rights was ordered on Thursday to leave Venezuela by the government of President Nicolás Maduro, an extraordinary move that will further strip the country of foreign oversight at a time when its government stands accused of intensifying repression.The announcement by Yván Gil, the foreign minister, comes just days after the detention and disappearance of Rocío San Miguel, a prominent security expert and human rights advocate.Following her detention, several U.N. entities issued online statements expressing concern about the arrest, some calling it part of a pattern in which the government tries to silence critics through intimidation.Mr. Gil said he was giving the staff of the U.N. Office of the High Commissioner for Human Rights 72 h...

Faced with declining foreign investment at home, China has sought to soften its image in the United States and Europe and make nice with some of its neighbors. One Communist Party official has played an unusually prominent role in the shift in tone.In New York, he told an audience of scholars and businesspeople that China did not seek to rewrite the United States-led global order. In Paris, he said that China’s modernization would benefit Europe and the world. In Beijing, he told the ambassador of India, a regional rival, that China hoped relations would “return to a healthy and stable” track.The official, Liu Jianchao, heads the Communist Party’s diplomatic arm, a body that promotes the party’s ideology and influence abroad. His recent engagements suggest to analysts, however, that he has...

It was near the start of one of Brazil’s most famous Carnival celebrations, in the northern seaside city of Olinda, and the town plaza was jammed with thousands of revelers. They were all awaiting their idol.Just before 9 p.m., the doors to a dance hall swung open, a brass band pushed into the crowd and the star everyone had been waiting for stepped out: a 12-foot puppet of John Travolta.Confetti sprayed, the band began playing a catchy tune and the crowd sang along: “John Travolta is really cool. Throwing a great party. And in Olinda, the best carnival.” (It rhymes in Portuguese.)The giant John Travolta, perched on the head of a puppeteer, then led a parade through the cobblestone streets.The “boneco,” as such giant puppets are known in Brazil, wore a bedazzled disco-era turtleneck and su...

Less than two weeks after bombs began raining down on the Gaza Strip, Ghada al-Kurd arrived in the southern city of Khan Younis. She had already been displaced three times, and hoped it would be her final journey to safety. But three months later, Israeli forces advanced south. Ms. al-Kurd, 37, speaking by telephone, said she, her sister, brother-in-law, and four nieces and nephews abandoned the tent they had been sharing “without taking anything with us,” and headed to Rafah, Gaza’s southernmost city.Many of the roughly 1.7 million Gazans that U.N. agencies say have been displaced by Israel’s relentless bombardment and ground invasion have fled repeatedly over the course of a war that had now entered its fifth month. And Ms. al-Kurd’s family members number among more than a million peopl...

For about 350 years, humanity’s most innovative hand-held computer was something called a slide rule. As typewriters once symbolized the writer, slide rules symbolized the engineer.These analog calculators came in metal, wood, plastic and even bamboo, and they could be found all over the world. Their functions included computing higher-order multiplications, exponents and logarithms, among other mathematical operations. They were usually long and rectangular with a retractable middle segment, and they featured dense fields of letters, lines and numbers stacked on top of one another.They looked almost comically abstruse, as if they might be used as paddles in the hazing rituals of a math fraternity.Non-nerds struggled to make sense of them. Then, in the early 1970s, lightweight electronic c...

Russian authorities on Thursday banned from the presidential race the only candidate who had openly contested President Vladimir V. Putin’s hold on power in Russia, and who called the decision to invade Ukraine a “fatal mistake.”The move by Russia’s Central Electoral Commission, the body that administers elections in Russia, was the latest predictable twist in a campaign that few doubt will result in Mr. Putin’s re-election in March.Mr. Putin’s expected victory in the March 15-17 presidential election would secure him a fifth term in the Kremlin, cementing his rule as one of the longest and most consequential in Russian history.The commission’s dismissal of the antiwar candidate, Boris B. Nadezhdin, demonstrated how the Kremlin has decided to remove all contenders who deviate from the part...

In the ancient prehistory of Earth, there is a chapter that waits to be told known as Romer’s gap. Researchers have identified a hiatus in the tetrapod fossil record between 360 million and 345 million years ago, after fish had begun to adapt to land and more than 80 million years before the first dinosaurs.While mysteries remain about evolution’s experiments with living things during that 15-million-year gap, a fossilized tree described in a new paper offers greater insights to some of what was happening during this period in nature’s laboratory.Named Sanfordiacaulis densifolia, the tree had a six-inch diameter with a nearly 10-foot-tall trunk composed not of wood, but of vascular plant material, like ferns. Its crown had more than 200 finely striated, compound leaves emanating from spira...

Senate Republicans and Democrats on Sunday cemented a compromise plan to crack down on unlawful migration across the U.S. border with Mexico and cleared a critical hurdle to an aid package for Ukraine, but the deal faces long odds in a Congress deeply divided over both issues.The release of the agreement, struck after more than three months of near-daily talks among senators and Biden administration officials, counted as an improbable breakthrough on a policy matter that has bedeviled presidents of both parties and defied efforts at compromise for decades on Capitol Hill. President Biden implored Congress late last month to pass it, promising to shut down the border immediately once it became law.But Speaker Mike Johnson has pronounced it “dead on arrival” in the Republican-controlled Hous...

Ever since a shipwreck washed ashore in the remote Canadian coastal area of Cape Ray on the island of Newfoundland in late January, it’s been causing a stir in the small community of about 250 people.Residents have posed for pictures with parts of the wooden ship, which a local hunter spotted and which is believed to be from the 19th century. They’ve encouraged the authorities to secure the structure. And they’ve speculated on social media about its mysterious origins.The posts, on a community page on Facebook, caught the attention of a local photographer, Corey Purchase, who lives 15 minutes from the area. He used a drone to take aerial photos showing the scale of the vessel, which he estimated to be about 90 feet long.“The drone put it into perspective for sure,” he said. “It was a prett...

As Israel awaited a signal from Egyptian and Qatari mediators about whether Hamas’s military leaders were prepared to advance talks on a possible cease-fire and hostage release, differences among the families of the more than 100 captives remaining in Gaza were emerging.Some are pushing for a deal at all costs, while others are urging the government to fight on against Hamas until victory. For months, the families of the hostages have been a key — and largely united — voice in putting pressure on the Israeli government to prioritize efforts to secure their release. Now some are backing calls for a tougher stance toward Hamas, including blocking all aid to Gaza, even as the government is under international pressure to increase humanitarian assistance.Those differences have added to politic...
