Despite living through one of the most politically and racially divisive eras in U.S. history, the youngest of voting-age Americans — especially those of color —appear more hopeful about the country's future than they were four years ago, a new poll released Friday finds.

The Harvard Youth Poll of 2,513 Americans between the ages of 18 and 29 conducted from March 9 to March 22, found them expressing significantly more optimism than in the months after Donald Trump became president.

The U.S. is joining an international search for a missing Indonesian submarine that lost contact with its base earlier this week. Authorities said the KRI Nanggala 402, if still intact, may by now have exhausted its oxygen supply for its crew of 53.

Pentagon spokesperson John Kirby announced Thursday evening on Twitter that at Indonesia's request, the U.S. was "sending airborne assets to assist in the search for the missing submarine."

Russian jailed opposition leader Alexei Navalny said Friday he is calling off a more than three-week prison hunger strike that doctors say left him near death.

Russia says it will begin a phased reduction of troops from its border with neighboring Ukraine – apparently ending a deployment that had alarmed Kyiv and Western observers concerned about a possible repeat of Moscow's 2014 annexation of Crimea.

After making the first powered flight on another world, NASA's Mars 2020 mission has managed another key first that could pave the way for future astronauts by making breathable oxygen out of the wispy Martian air.

Rescuers scouring the Bali Sea for a stricken Indonesian submarine with 53 sailors aboard are hoping the crew could still be alive, but as the hours since the vessel's disappearance tick by, the chances of survival grow increasingly slim.

Governors from a dozen states are asking President Biden to ban the sale of cars and light trucks that emit greenhouse gases by 2035.

In a letter to the president, the governors of California, New York, North Carolina and nine other states — all but one a Democrat — asked for the change ahead of a White House climate summit, scheduled to begin Thursday.

Indonesia's navy has lost contact with a submarine carrying 53 sailors that was preparing for a weapons training exercise in waters north of Bali, a military spokesman said Wednesday.

The German-built KRI Nanggala-402, which went into service in the early 1980s, failed to relay results of the exercise as expected, Julius Widjojono said, according to Reuters.

Indonesia's defense ministry said that an aerial search had spotted an oil slick on the water near where the submarine is thought to have performed a dive.

The European Union's drug regulator said Tuesday it had concluded there is a "possible link" between the Johnson & Johnson COVID-19 vaccine and several cases in the U.S. of a rare type of blood clot, but emphasized that the shot's benefits "in preventing COVID-19 outweigh the risks of side effects."

Idriss Déby Itno, the president of Chad and one of Africa's longest-serving leaders, was killed in the country's north, where he had traveled to observe the fight against rebel insurgents, state media reported Tuesday.

The announcement came just hours after election officials in Chad certified that Déby, 68, had carried nearly 80% of the vote in April 11 polls, setting him up for a sixth five-year term as president.

The American ambassador to Russia is returning to Washington, D.C., for "consultations" after President Biden imposed a new round of sanctions on Moscow last week, including the expulsion of 10 diplomats — a move quickly followed by reciprocal measures from the Kremlin.

The fate of former Minneapolis police officer Derek Chauvin, on trial for the killing of George Floyd in May 2020, is now in the hands of the jury.

Chauvin's trial entered its seventh week Monday with Hennepin County Judge Peter Cahill's instructions to jury members, followed by closing arguments from prosecution and defense attorneys. Jurors will be sequestered during their deliberations.

In closing arguments, prosecutor Steve Schleicher said Chauvin directly caused the death of Floyd on Memorial Day after kneeling on Floyd's neck for 9 minutes and 29 seconds.

As historic moments go, this one was very much one with the times.

Socially distanced and mask-wearing controllers and engineers, seated before laptops in matching orange polo shirts designed for the mission, waited anxiously Monday morning at the Jet Propulsion Laboratory in Pasadena, Calif., for news of the first powered flight on another world.

Several other mission personnel were just as eagerly waiting virtually elsewhere.

Alexei Navalny, Russia's jailed hunger-striking opposition leader, has been transferred to a prison infirmary after 20 days without food amid a warning from his doctor that he could die "at any minute."

Russian prison authorities said Monday that Navalny has been moved to a medical ward at prison separate from the one where he was being held. He will undergo "vitamin therapy" there, they said.

Navalny's personal physician, Dr. Yaroslav Ashikhmin, said over the weekend that test results he's reviewed show that Navalny is at an elevated risk of cardiac arrest.

Russia retaliated Friday over a new round of U.S. sanctions imposed a day ago by the Biden administration over the SolarWinds cyberattack and the Kremlin's election meddling.

Foreign Minister Sergey Lavrov said 10 U.S. diplomats will be expelled from Russia, mirroring the 10 Russian diplomats ordered to leave the U.S. on Thursday. Moscow will also add eight U.S. officials to its sanctions list and will restrict the activities of U.S. nongovernmental organizations, or NGOs, operating in Russia.

A generation of Cuban revolutionaries who seized power more than six decades ago, directly challenging the U.S. and later pushing Washington and Moscow to the brink of nuclear war, is set to exit the stage.

President Biden is ordering a new round of economic sanctions on Russia — a response in part to Moscow's election meddling and a Kremlin-linked computer breach that penetrated numerous U.S. government networks.

Biden said Thursday that the United States isn't pushing for "a cycle of escalation and conflict" with Russia, but instead for both nations to manage tensions and work together when needed.

U.S. Secretary of State Antony Blinken arrived in Kabul on Thursday in an unannounced visit that comes just a day after President Biden announced he has decided to withdraw all U.S. troops from Afghanistan, ending America's longest conflict.

The top U.S. intelligence officials on Wednesday provided their assessment of worldwide threats affecting U.S. interests, focusing on cybersecurity and military concerns posed by Beijing and Moscow, but also the threat of both domestic and international terrorism.

It was the first such assessment formally presented at a hearing to Congress in two years due to tensions between former President Donald Trump and the nation's intelligence community.

The U.S. Centers for Disease Control and Prevention and the Food and Drug Administration said Tuesday they are recommending a "pause" in the use of the single-dose Johnson & Johnson COVID-19 vaccine out of an "abundance of caution" while a review of reports of rare, potentially dangerous blood clots is conducted.

North Korean leader Kim Jong Un is calling for his country to prepare for another "arduous march" — using a phrase that has come to describe a disastrous famine in the 1990s that killed hundreds of thousands of people.

Speaking Thursday to members of the Workers' Party of Korea, or WPK, Kim referred to "many obstacles and difficulties ahead of us," according to the official Korean Central News Agency, or KCNA.

The government of Northern Ireland is holding an emergency meeting on Thursday following days of unrest reminiscent of "The Troubles" that plagued the region for decades.

The latest violence in Belfast has erupted amid anger from Protestant unionists concerned they're being isolated from the United Kingdom and pushed into a union with the republic of Ireland due to post-Brexit trade rules.

A more easily spread coronavirus variant first identified in England last year has now become the dominant strain in the U.S., the head of the Centers for Disease Control and Prevention said Wednesday.

The variant, known as B.1.1.7, spread quickly across the United Kingdom and Ireland beginning last fall, with the more infectious version of the coronavirus thwarting restrictions and lockdowns that had earlier helped keep the original strain in check.

Voters in Greenland have given an opposition party its first-ever chance to form a government after a campaign that sought to define the limits of development on the Arctic island.

The Inuit Ataqatigiit party won 37% of the vote, compared with 29% for the ruling social-democratic Siumut party, according to official results reported by Reuters. The vote totals should allow Inuit Ataqatigiit to grab 12 seats in the 31-member unicameral legislature, known as the Inatsisartut, meaning it will likely need to form a coalition with support from one of the smaller parties.

A new surge of COVID-19 in Brazil is filling hospitals and morgues, as the country's record daily death toll from the disease is nearing even the grim U.S. peak in January.

With less than two-thirds the population of the U.S., Brazil logged nearly 4,200 deaths on Tuesday. That is close to the peak U.S. daily death toll of 4,476 recorded on Jan. 12, according to data maintained by Johns Hopkins University.
