finally over rare, but sometimes fatal, blood clots reported in some recipients.
Those concerns led several European countries to first restrict the use of AstraZeneca in older age groups, then suspend it over reports of blood clots, only to roll it out again last month after the European Medicines Agency issued a preliminary opinion that the benefits of the vaccine outweighed the risks.
As doctors reported a higher incidence of serious blood clots in younger people, some countries decided to stop administering the shot to anyone younger than 55.
Europe’s concerns over the vaccine’s side effects are also likely to threaten global inoculation efforts, with much of the developing world depending on the AstraZeneca vaccine to tackle the pandemic. The shot is the cornerstone of Covax, a program designed to make vaccine access more equitable worldwide.
The vaccine appeared to be causing an immune reaction in which antibodies bind to platelets, activating them, German doctors and the European Medicines Agency have said. Those platelets, in turn, were causing the formation of dangerous clots in certain parts of the body, including in veins that drain blood from the brain, leading in some cases to a rare type of stroke.
Why the antibodies develop in these people is not known, doctors have said. Some component of the vaccine, or excessive immune reaction — or both — could be the cause, they said.
No pre-existing conditions are known to make patients more vulnerable to this clotting disorder after a vaccination, European regulators said.
Nearly 80 percent of school staff and child care workers in the United States have received at least one dose of the coronavirus vaccine, the Centers for Disease Control and Prevention said on Tuesday.
The announcement comes as the Biden administration has made an ambitious push to reopen schools and return to in-person instruction by the president’s 100th day in office. That goal has been tempered by dangerous virus variants, protests from teachers’ unions, and the fears and frustrations of students and parents.
The push to reopen schools has gathered momentum as evidence mounted that proper safety measures limited virus transmission in schools and coronavirus cases fell sharply from their January peak. Education officials and experts have cited the urgency of getting students back in classrooms before the academic year ends.
About eight million teachers, school staff and child care workers received their first vaccine dose by the end of March, according to the C.D.C., with about two million receiving their shot through the Federal Retail Pharmacy Program.
President Biden announced the program in March, urging nationwide access to vaccines for school employees and child care workers. But a hodgepodge of eligibility guidelines followed, as some states chose not to deviate from their rollout plans. By the end of March, however, K-12 educators in all states had become eligible to receive the vaccine.
While the acceleration of vaccinations among educators and staff has reduced the resistance from teachers’ unions to reopening classrooms, school systems with powerful unions, especially on the West Coast, have been slower to revert to in-person instruction.
Union resistance has led a bipartisan group of governors in several states to prod, and sometimes force, school districts to open. The result has been a major increase in the number of students who now have the option of attending school in-person, or will soon.
According to a school reopening tracker created by the American Enterprise Institute, 7 percent of the more than 8,000 districts being tracked were fully remote on March 22, the lowest percentage since the tracker was started in November. Forty-one percent of districts were offering full-time in-person instruction, the highest percentage in that time. Those findings have been echoed by other surveys.
In February, the C.D.C. issued guidelines that said K-12 schools could reopen safely as long as they followed basic health protocols like masking or distancing.
More recently, it said that elementary students and some middle and high schoolers could be spaced three feet apart in classrooms, instead of six feet, as long as everyone was wearing a mask. Unions had used the six-foot guidance to oppose bringing children back for normal schedules.
“Our push to ensure that teachers, school staff, and child care workers were vaccinated during March has paid off and paved the way for safer in-person learning,” Dr. Rochelle Walensky, the center’s director, said in a statement released on Tuesday.
Mr. Biden touted the C.D.C.’s newly released benchmark while visiting a vaccination site in Alexandra, Va., on Tuesday.
“That is great progress protecting our educators and our essential workers,” Mr. Biden said of the new estimate. “And because our vaccine program is in overdrive, we are making it easier to get a vaccination shot.”
The American Federation of Teachers, the nation’s second-largest teacher’s union, on Tuesday released a survey that reported over 80 percent of association members had been vaccinated or had made a vaccine appointment. About 85 percent of members said their school was “operating on at least a part-time basis,” according to the survey.
Randi Weingarten, the federation’s president, said in a statement on Tuesday that “A.F.T. members have embraced vaccines as vital to getting back in the classroom.”
“They want to return, the road map to reopening is robust, and if we instill trust and meet fear with facts we can finally end this national nightmare,” Ms. Weingarten said.
Around the United States, businesses, schools and politicians are considering “vaccine passports” — digital proof of vaccination against the coronavirus — as a path to reviving the economy and getting Americans back to work and play.
New York has rolled out “Excelsior Pass,” billed by the state as “a free, fast and secure way to present digital proof of Covid-19 vaccination” in case reopening sports and entertainment venues require proof of attendees’ status.
Walmart is offering electronic verification apps to patients vaccinated in its stores so they “can easily access their vaccine status as needed,” the company said.
But the idea is raising charged legal and ethical questions: Can businesses require employees or customers to provide proof of vaccination against the coronavirus when the vaccine is ostensibly voluntary?
Can schools require that students prove they have been injected with what is still officially an experimental prophylaxis the same way they require long-approved vaccines for measles and polio? And finally, can governments mandate vaccinations — or stand in the way of businesses or educational institutions that demand proof?
Legal experts say the answer to all of these questions is generally yes, though in a society so divided, politicians are girding for a fight. Government entities like school boards and the Army can require vaccinations for entry, service and travel — practices that flow from a 1905 Supreme Court ruling that said states could require residents to be vaccinated against smallpox or pay a fine.
Backers of digital vaccination cards are pressing the Biden administration to become involved, at least by setting standards for privacy and for verifying the accuracy of the records.
The White House is clearly skittish.
“The government is not now nor will we be supporting a system that requires Americans to carry a credential,” Jen Psaki, the White House press secretary, said on Tuesday.
Republican critics say vaccine passports raise the specter of centralized databases of vaccinated people, which they view as a government intrusion on privacy.
“A vaccine passport — a unified, centralized system for providing or denying access to everyday activities like shopping and dining — would be a nightmare for civil liberties and privacy,” Justin Amash, a former Republican congressman who is now a libertarian, wrote on Twitter last week.
But, in fact, every state already has a database, or an “immunization registry.” And under “data use agreements,” the states are required to share their registries with the C.D.C., though the agency de-identifies the information and not all states have agreed to provide it.
Three weeks after suspending its vaccination campaign, Nepal has started administering shots again thanks to a gift of doses from China.
Nepal, a poor Himalayan nation, had been depending on vaccines manufactured in neighboring India, but last month India began cutting vaccine exports as the country experienced a surge in coronavirus cases. Nepal’s vaccination effort ground to a halt, even as infections began to rise again.
Last week, Nepal’s other giant neighbor, China, stepped in with a donation of 800,000 doses of the vaccine developed by Sinopharm, a state-owned company.
The vaccines will be administered to essential workers, Nepali students preparing to travel to China to study and those living in districts along the Nepal-China border, health officials said. Taranath Pokhrel, a senior official in Nepal’s health department, said that the Chinese government asked Nepal to give priority to the students and to people involved in cross-border trade, presumably to reduce the risk of infected people crossing into China.
Thousands of Nepali students study at Chinese universities under Chinese government scholarships. China, to increase the appeal of its vaccines, has said that foreigners who are inoculated with Chinese-made vaccines may face fewer bureaucratic hurdles entering the country.
Nepal, a nation of 30 million people, has vaccinated more than 1.7 million and slowly begun reopening to visitors, including to a few hundred climbers attempting to scale Mount Everest. The country reported very few infections in January, but new cases have surpassed 300 in recent days, part of a worrying resurgence in new cases across South Asia. India, which shares a porous border with Nepal, recorded more than 115,000 new infections on Wednesday, by far its highest daily total since the pandemic began.
The future of Nepal’s vaccination campaign remains uncertain because the Chinese donation falls short of the two million vaccine doses Nepal was due to receive under an agreement with the Indian manufacturer, the Serum Institute of India. Nepal officials said that they had paid the company 80 percent of the contract price but received only half of the doses. Serum’s chief executive said this week that he hoped to restart exports by June if new infections in India subsided.
“Our entire diplomatic channels are mobilized to get vaccines, but none has assured us of providing vaccines when we tried to procure them,” Dr. Pokhrel said.

In Japan, officials in Osaka canceled public Olympic torch relay events scheduled for next week and declared a medical emergency as a surge in coronavirus cases strains the hospital system. The prefecture’s 8.8 million residents were asked not to leave their homes except for essential matters. Olympic organizers said the ceremonial relay would be held at a park without spectators — the latest sign of trouble with the Tokyo Olympics scheduled to open in less than four months.
The Moderna vaccine is now being administered in Britain, with a 24-year-old woman in Wales who is a caregiver for her grandmother the first person in the country to receive that vaccine on Wednesday. The Pfizer and AstraZeneca shots are already being used in the country. Vaccinations in Britain have slumped this month, reaching their lowest level since the inoculation campaign started. In a Twitter post, Prime Minister Boris Johnson urged people to “get your jab as soon as you are contacted.”
Regulators in South Korea granted final approval to the Johnson & Johnson vaccine, making it the third vaccine authorized for use in the country amid growing concerns about the pace of its inoculation campaign. Officials reported 668 new coronavirus cases on Wednesday, the highest tally in three months, with most of the cases found in Seoul and other major cities.
Germany’s troubled vaccine rollout may face another hurdle after a shipment of up to 880,000 Moderna vaccines that had been promised for the end April was canceled, the news site Business Insider reported. Separately on Wednesday, state and federal health ministers were meeting to discuss how to handle cases of people who have received a first dose of the AstraZeneca vaccine after that shot use was discouraged for use in people under 60.
Chancellor Angela Merkel of Germany has called for a short and strict nationwide lockdown to bring down the number of new coronavirus infections in the country, according to her spokeswoman, but will meet with local officials next week to discuss potential regulations.
A year after the first lockdown was successful in tamping down cases, the country’s 16 governors are finding it harder than ever to agree on a unified plan to stem new infections. And with only months left in office, Ms. Merkel has found it increasingly difficult to rally support for a national lockdown as fatigue from prolonged restrictions looms large even as cases rise.
The governors and Ms. Merkel are scheduled to meet on Monday to hammer out new regulations.
While Armin Laschet, the governor of the country’s most populous state and a potential successor to Ms. Merkel, has made similar calls for a two- to three-week hard lockdown to bring down infections, other governors are pushing back. The governor of one small state even began a pilot program on Tuesday to reopen theaters, gyms and restaurant patios.
“A common nationwide approach would also be important here,” Ulrike Demmer, the deputy government spokeswoman, said during a daily news conference, referring to the confusing and often contradictory rules set by state governors. Ms. Demmer also pointed to the rising number of coronavirus patients in intensive care wards as a cause for concern.
According to Ms. Demmer, the goal is to get the infection rate below 100 new cases per 100,000 before the authorities should consider easing restrictions.
On Tuesday, the German health authorities recorded an average of 110 infections per 100,000 people over the previous 7 days, but warned that because fewer people were tested over the Easter holiday weekend, the number was likely to be much higher.
According to a New York Times database, Germany is averaging 15,562 new infections daily and since the pandemic began. More than 77,000 have died with the disease in the country since the pandemic began.
A 28-year-old man has died in the Philippines after the police forced him to do 300 squats as punishment after he was caught violating coronavirus lockdown rules.
The man, Darren Manaog Peñaredondo, was detained on Thursday in General Trias city, a Manila suburb, over a curfew violation. Officials have struggled to contain infections in the southeast Asian nation and have increasingly resorted to harsh tactics to enforce restrictions, rights groups say.
He was released the following day, but first was forced to complete 300 squats, his relatives said.
It is not the first time that the authorities have been accused of using aggressive tactics against civilians during the pandemic. President Rodrigo Duterte told the police last year not to be afraid to shoot anyone who “causes commotion,” after 20 people protesting restrictions were arrested. Last year, a former soldier suffering from mental health issues was gunned down by the police as he tried to cross a coronavirus checkpoint.
Mr. Peñaredondo’s partner, Reichelyn Balce, said that when he returned home on Friday after being detained, he had shown signs of fatigue.
“He told me that he fell when doing the exercises,” she said. “He struggled to walk when he got home. When he went to relieve himself, he turned blue and convulsed.”
She said that Mr. Peñaredondo was revived but he later died.
Two police officers who imposed the harsh punishment have been suspended pending the results of an investigation into their actions, said Brig. Gen. Ildebrandi Usana, a national police spokesman.
The local police had initially denied the events, but two men who were detained with Mr. Peñaredondo signed a sworn statement about the ordeal.
Cristina Palabay, who leads a local rights group called Karapatan, said that the police punishment amounted to “a form of torture that is cruel and inhuman” and signaled that the local police had adopted a “strongman approach.”
Ms. Palabay’s group aids families of the thousands of citizens killed in the president’s aggressive war on drugs.
The country’s Commission on Human Rights was critical of what it called an “overreach of the enforcement of quarantine rules and regulations,” according to the body’s spokeswoman, Jacqueline Ann de Guia.
Ms. de Guia said that curfew violations called for community service or a fine, rather than harsh physical punishment.
Kenna Tanner and her team can list the cases from memory: There was the woman who got tired and did not feel like finishing her hike; the campers, in shorts during a blizzard; the base jumper, misjudging his leap from a treacherous granite cliff face; the ill-equipped snowmobiler, buried up to his neck in an avalanche.
All of them were pulled by Ms. Tanner and the Tip Top Search and Rescue crew from the rugged Wind River mountain range — the Winds, as the range is known locally — in the past year in a sprawling, remote pocket of western Wyoming. And all of them, their rescuers said, were wildly unprepared for the brutal backcountry in which they were traveling.
“It is super frustrating,” said Ms. Tanner, Tip Top’s director. “We just wish that people respected the risk.”
In the throes of a pandemic that has made the indoors inherently dangerous, tens of thousands more Americans than usual have flocked outdoors, fleeing crowded cities for national parks and the public lands around them. But as these hordes of inexperienced adventurers explore the treacherous terrain of the backcountry, many inevitably call for help. It has strained the patchwork, volunteer-based search-and-rescue system in America’s West.
Where places like Canada or Switzerland have professional, full-time teams that manage everything from lost tourists to fatal mountaineering accidents, most operations in the United States are handled by a loose network of volunteer organizations like Tip Top, which are overseen by local sheriffs.
For much of the country’s history, this patchwork system met demand. But that trend has shifted in the past decade — and rapidly, over the past year — as less experienced recreationalists push further into treacherous places.
No one expects the eventual end of the pandemic to stem the flood of newcomers to the Winds, which people grudgingly admit have been discovered. Property values continue to soar in Sublette County, and even this winter, locals say out-of-state plates were more common than Wyoming plates in trailhead parking lots.
“You can’t stop it,” said Chris Hayes, who works at an outdoor retailer in Pinedale and also runs a fishing guide service. “There’s no secret place anymore. They’re all gone.”
Before the pandemic, I found comfort in the routine of my life and the rhythms of my family — what Nora Ephron once called the “peanut-butter-and-jellyness” of days with children. I liked the morning thunderdome of getting the children dressed and fed, dropping them at school and taking the 20-minute walk to the subway.
At this point my commute is the five feet from my bed to my desk, and I am somehow both tired and agitated when I start work each day. My kids never leave the house, except when we go to the same three parks in our neighborhood. Sometimes when I go running outside, I fantasize about just … not stopping, my eyes thirsty for some new horizon.
In other words, I’m so freaking bored.
Here’s how one boredom researcher — yes, there are boredom researchers — has defined the emotion. “‘Feeling unchallenged’ and perceiving one’s ‘activities as meaningless’ is central to boredom,” concluded a study by Wijnand Van Tilburg, an experimental social psychologist at the University of Essex in England.
Even in normal times, boredom is a very common emotion — a study of almost 4,000 American adults found that 63 percent felt bored at least once in a 10-day sampling period. The causes of boredom are multifaceted, but a lack of control over your situation is a common one. He added, “There’s research that shows when you’re limited in your control over the situation — that intensifies boredom.”
Knowing that many of us may not be able to have much control over our movements for at least the next few months, how do we try to alleviate our boredom? First, the researchers I spoke to said it’s important to acknowledge there’s no easy fix for our doldrums — so much of what is happening right now is beyond our control, and the vaccines are just beginning to be tested in children under 12, so we may not be able to make big moves just yet.
This weekend, we saw relatives I adore for an outdoor Easter egg hunt. Just 90 minutes of warm interaction with these beloved adults made me feel so happy and alive that I was smiling for the rest of the day.
As the weather gets warmer and more of my peers are inoculated, I am planning more get-togethers. Whenever I drop back into the doldrums, I will think about all the walks and dinners and hugs on the horizon.
Stress-baking and panic shopping. Vegetable regrowing and crafting. Now we can add another hobby to a year of quarantine trends: backyard maple sugaring.
Among the many indicators that it’s on the rise: a run on at-home evaporators and other syrup-making accouterments. A surge in traffic and subscriptions to syrup-making websites and trade publications. And, of course, lots of documentation on social media. (The Facebook group Backyard Maple Syrup Makers added some 5,000 members, almost doubling the its community, in the past year.)
Tapping maple trees and boiling the sap into syrup — known as sugaring — isn’t a new hobby. What’s unique about this year is the influx of suburban and urban backyard adventurers fueling these maple sugaring highs.
Claire and Thomas Gallagher, for example, tapped a tree behind their home in New Rochelle, N.Y., for the first time three weeks ago.
“It’s such a fun thing to do with the kids, it gets us outside, it’s educational,” Ms. Gallagher, 37, said. And with everyone at home all winter and probably the spring as well, the Gallaghers decided there would never be a better year to try it.
Because sugaring is a sticky business — and boiling sap indoors can mean resin all over the walls — many backyard amateurs turn to small-scale, hobby-size evaporators like the ones sold by Vermont Evaporator Company in Montpelier, Vt.
“When we started our company five years ago, our customers used to look just like us: rural homeowners with five to 10 acres of land,” said Kate Whelley McCabe, the chief executive. “Now we sell to people all over the country and to a growing number of suburban and urban customers.”
The governor of New Hampshire, Chris Sununu, is a dedicated sugarer. His 8-year old son, Leo, is his tree tapping assistant, and his two teenagers, Edie and Calvin, “do the heavy lifting.”
Governor Sununu said that when the tree sap begins to flow, it’s the official signal that spring has arrived. “It’s been a long winter and a long year. The sun is coming up, the days are getting warmer, and when the sap ran this year, we knew we were really coming out of winter with a lot of optimism,” he said in an interview.
begun adding back jobs after a winter lull. But he will note that those metrics may not capture the full extent of the damage to workers.
“However, the sectors of the economy most adversely affected by the resurgence of the virus, and by greater social distancing, remain weak, and the unemployment rate — still elevated at 6.2 percent — underestimates the shortfall,” Mr. Powell is set to say.
The Fed chair will add that the central bank, which has rates at near-zero and is buying bonds to keep credit flowing and to bolster the economy, “will not lose sight of the millions of Americans who are still hurting.”
Mr. Powell will say the Fed’s many market-facing programs in 2020, which supported credit to corporations, midsize businesses and municipalities, helped to “keep organizations from shuttering and put employers in both a better position to keep workers on and to hire them back as the recovery continues.”
And he will underline that the programs, in most cases, have either shut down or will soon end. Mr. Powell consistently has said that the lending efforts, supported by the Treasury, were emergency tools that the Fed would stop using once conditions were stable.
Cineworld, the parent company of the U.S. movie theater chain Regal Cinemas, announced on Tuesday that it would reopen its cinemas in the United States in April and in Britain in May as those countries ease lockdown restrictions.
“We have long-awaited this moment,” said Mooky Greidinger, the chief executive of Cineworld, which is based in London. “With capacity restrictions expanding to 50 percent or more across most U.S. states, we will be able to operate profitably in our biggest markets.”
Regal Cinemas is the second largest theater chain in the United States, after AMC Theaters. The announcement by Cineworld comes six months after the movie theater chains were forced to shut down across the United States and Britain last October in an effort to curb the spread of the coronavirus. The decision affected a total of 45,000 employees in both countries and forced studios to postpone film releases.
Cineworld also announced a multiyear agreement with Warner Bros. starting in 2022 that will allow the theater chain to show the studios’ films for 45 days in the United States and 31 days in Britain. The deal shortens the typical window that theaters have to show movies before they are released to on-demand streaming services.
The reopening plans in the United States will coincide with the release of two movies from Warner Bros. Pictures, “Godzilla vs. Kong” on April 2 and “Mortal Kombat” on April 16.
“We are very happy for the agreement with Warner Bros.,” Mr. Greidinger said. “This agreement shows the studio’s commitment to the theatrical business.”
Last week, AMC Theaters announced the reopening of nearly all of its U.S. theaters.
The moves come at a time of concern that looser restrictions will lead to rise in coronavirus cases. On Monday, the director of the Centers for Disease Control and Prevention warned that relaxed pandemic restrictions could lead to another spike. “If we don’t take the right actions now,” said Dr. Rochelle Walensky, “we will have another avoidable surge.”
In September, Cineworld reported a pretax loss of $1.6 billion for the first half of 2020. In 2019, 90 percent of the company’s revenue was generated in the United States and Britain.
Mayor Francis Suarez of Miami is selling his city as the world’s cryptocurrency capital. “We want to be on the next wave of innovation,” he told the DealBook newsletter.
To make that happen, Mr. Suarez said he was “refashioning” the city’s “fun in the sun” image. Thanks in part to the mayor’s marketing efforts, tech and finance titans have flocked to Miami during the pandemic.
Last month, Mr. Suarez, a Republican, suggested Miami pay municipal workers and accept tax payments in Bitcoin, as well as invest city funds in the cryptocurrency. Local officials have agreed to study the proposals.
The notion has made Mr. Suarez popular in the crypto community, advancing his rebranding campaign. His efforts have also won him campaign donations from tech investors, attracted money to cultivate Miami’s growing tech sector and may soon pay a big county bill.
The cryptocurrency exchange FTX is seeking naming rights for the city’s N.B.A. arena, known as AmericanAirlines Arena. Miami-Dade County took over branding deals in 2018 and is supposed to pay the team $2 million per year, sponsor or no (American Airlines’ contract ended in 2019). The FTX agreement is nearly final, pending a vote by county commissioners on Friday. “It’s awesome that we’ve attracted a huge cryptocurrency exchange,” Mr. Suarez said, noting that FTX’s bid “complements the brand” that Miami is establishing.
It would be the N.B.A.’s first crypto sponsorship of an arena, but it would also tie a county revenue stream to a relatively young exchange and chief executive. FTX was founded in 2019 and is run by Samuel Bankman-Fried, a 28-year-old billionaire who was one of the biggest donors to President Biden’s campaign.
The pandemic has prompted people to relocate to Florida from Silicon Valley and New York as Bitcoin gained legitimacy and value. The mayor sees the trends as interrelated, and he is seizing the moment.
“People come here and start realizing that there’s way more tech talent than they thought,” he said. All that’s missing, he added, is a regulatory overhaul: Lawmakers are modeling Florida’s approach on Wyoming’s crypto policies.
But the success of the mayor’s effort won’t be apparent until it’s clear that people are making their moves permanent and maintaining their enthusiasm for crypto if — or when — there is another market downturn.
Stocks fell on Tuesday, with the S&P 500 opening slightly lower, amid new concerns about the global economic recovery from the pandemic.
Europe has been reporting a rise in new virus cases and increasing lockdown restrictions. Fresh confusion about the AstraZeneca vaccine were raised on Tuesday morning as U.S. health authorities questioned whether some of the U.S. trial data submitted by the drugmaker was outdated.
Investors were awaiting testimony from Treasury Secretary Janet Yellen and the Federal Reserve chair, Jerome H. Powell, about the recovery of the U.S. economy. They will be questioned by the House Financial Services Committee later Tuesday. According to prepared remarks, Mr. Powell is expected to tell lawmakers that “while the economic fallout has been real and widespread, the worst was avoided by swift and vigorous action.”
In the Markets
Wall Street slipped on Tuesday, coming off a 0.7 percent rise in the S&P 500 on Monday. European indexes were trading lower, with the Stoxx Europe 600 down 0.13 percent. Investors turned to traditional safe assets such as U.S. Treasury bonds, and the 10-year yield dropped slightly to 1.65 percent.
Energy prices fell. West Texas Intermediate, the U.S. crude benchmark, is down 4.3 percent, back below $60 a barrel. Brent, the international benchmark, fell by 4.5 percent, below $62 a barrel. Natural gas also fell.
GameStop’s chief customer officer, Frank Hamlin, will leave the company at the end of the month, according to a regulatory filling on Tuesday. The video game retailer, which was at the center of a retail trading frenzy earlier this year that sent its share price soaring, will release its quarterly earnings later on Tuesday. Last month, GameStop also said its chief financial officer, Jim Bell, would leave. The company is under pressure from an activist shareholder to complete a digital transformation.
Microsoft shares opened up more than 1 percent after reports late Monday that the company was in talks to acquire Discord, a social media company popular with gamers.
Baidu, the Chinese search company that some people once called the Google of China, raised $3.1 billion in a share listing in Hong Kong on Tuesday, the latest homecoming of a Chinese company against a toughening regulatory backdrop in the United States.
Investors showed a muted appetite for the company, which already has a listing in New York and has been eclipsed by other Chinese technology firms in recent years. In the United States, Google has used its search power to become a dominant internet company, but Baidu has not grown as quickly as Alibaba, the Chinese e-commerce company, or Tencent, a conglomerate with holdings in video games and social media.
Its stock finished its first day trading on the Hong Kong exchange flat at 252 Hong Kong dollars, or about $32, a share.
The broader Hang Seng exchange fell 1.3 percent amid rising tensions between the United States and China. The United States said on Monday it would join the European Union, Canada and Britain in sanctioning Chinese officials over human rights abuses against China’s mostly Muslim Uyghur community.
Baidu follows other New York-listed Chinese companies like Alibaba, NetEase and JD.com in offering their shares to Chinese retail investors through a listing in the Chinese territory of Hong Kong. More companies have done “homecoming listings” in recent years as Chinese officials have tried to lure back companies that chose to list overseas.
Secondary listings by Chinese companies have also become more popular as American regulators have pledged to delist Chinese companies from their exchanges if they do not adhere to local accounting rules. Baidu is among a group of Chinese companies that has denied access to inspections by the Public Company Accounting Oversight Board, an auditing watchdog created by the U.S. government.
An executive order by former President Donald J. Trump preventing Americans from investing in companies deemed to have ties to the Chinese military has also led to an exodus of Chinese companies. The New York Stock Exchange delisted China Mobile, China Telecom and China Unicom earlier this year.
The Hong Kong market has shown less interest for secondary listings than it has for newer technology companies like Kuaishou, a short-video app, that nearly tripled in value on its debut last month and valued the company at $160 billion.
Baidu is valued at $92 billion on the Nasdaq stock market.
The Senate confirmed Martin J. Walsh, the mayor of Boston and a former leader of the city’s powerful building trades council, as labor secretary on Monday. The vote was 68 to 29.
The confirmation filled the last leadership role for the 15 executive departments in President Biden’s cabinet. Of nine other cabinet-level leadership roles, seven have been filled.
In a statement after the vote, Mr. Walsh said that he was grateful for the Senate’s bipartisan support and that he shared Mr. Biden’s and Vice President Kamala Harris’s “commitment to building an economy that works for all.”
“I have been a fighter for the rights of working people throughout my career, and I remain committed to ensuring that everyone — especially those in our most marginalized communities — receives and benefits from full access to economic opportunity and fair treatment in the workplace,” Mr. Walsh said in the statement. “I believe we must meet this historic moment, and as the nation’s secretary of labor, I pledge to help our economy build back better.”
Mr. Walsh’s nomination had won widespread praise from union officials, who were enthusiastic about having one of their own oversee the department, a historical rarity. Many union officials regard his close relationship with the president as an advantage for labor groups.
“Because he enjoys mutual trust and respect with President Biden, he will be positioned to put labor’s concerns front and center on the national agenda,” Lee Saunders, president of the American Federation of State, County and Municipal Employees, said in an email.
One of Mr. Walsh’s top priorities as labor secretary will be re-energizing the Occupational Safety and Health Administration, which critics have accused of failing to protect workers during the pandemic. The safety agency recently put out new guidance to employers on protecting workers from Covid-19 and is considering a new rule to mandate safety measures that the Trump administration rejected.
The department has already moved to set aside a number of rules issued by the Trump administration that weakened worker protections. One of those rules would probably have deemed most gig workers to be independent contractors rather than employees, making them ineligible for the federal minimum wage and overtime pay.
Under Mr. Walsh, the department will be charged with crafting replacements for some of these rules. It will most likely move to expand other protections, such as raising the threshold — currently set at about $35,500 — below which most salaried workers are automatically eligible for time-and-a-half overtime pay.
As mayor, he offered support to undocumented immigrants whom federal officials were seeking to detain, pressed contractors to set aside at least 40 percent of their work on public construction projects for racial minorities, and created gender-neutral bathrooms in City Hall.
“If you know Marty Walsh, you know that he has transcended race and class lines and fights for all with a real focus on the vulnerable,” said Randi Weingarten, the president of the American Federation of Teachers.
Mr. Walsh plans to resign as mayor on Monday evening, according to an aide.
Federal officials are looking into a series of recent accidents involving Teslas that either were using Autopilot or might have been using it.
Autopilot is a computerized system that uses radar and cameras to detect lane markings, other vehicles and objects in the road. It can steer, brake and accelerate automatically with little input from the driver. Tesla has said it should be used only on divided highways, but videos on social media show drivers using Autopilot on various kinds of roads.
The National Highway Traffic Safety Administration confirmed last week that it was investigating 23 such crashes, Neal E. Boudette reports for The New York Times.
In one accident this month, a Tesla Model Y rear-ended a police car that had stopped on a highway near Lansing, Mich. The driver, who was not seriously injured, had been using Autopilot, the police said.
In February in Detroit, under circumstances similar to the 2016 Florida accident, a Tesla drove beneath a tractor-trailer that was crossing the road, tearing the roof off the car. The driver and a passenger were seriously injured. Officials have not said whether the driver had turned on Autopilot.
NHTSA is also looking into a Feb. 27 crash near Houston in which a Tesla ran into a stopped police vehicle on a highway. It is not clear if the driver was using Autopilot. The car did not appear to slow before the impact, the police said.
“The Ellen DeGeneres Show” has lost more than a million viewers, according to the research firm Nielsen, averaging 1.5 million viewers over the last six months, down from 2.6 million in the same period last year. This year’s season opener in September, in which Ms. DeGeneres apologized in the wake of reports of workplace misconduct at her show, had the highest ratings for an “Ellen” premiere in four years. But since then, the show has seen a 43 percent decline in viewers. Even with the complications affecting all talk shows during the pandemic, the show has suffered a steeper decline than its rivals. “Dr. Phil” is down 22 percent, and “The Kelly Clarkson” show has lost 26 percent of its viewers.
Some investors have started distancing themselves from Dispo, a fast-growing photo-sharing app, after its co-founder, the YouTube creator David Dobrik, became embroiled in controversy. In an investigation by Insider that published last week, Mr. Dobrik was accused of playing a role in a sexual assault scandal involving a former member of his “Vlog Squad.” He later told The Information that he would leave Dispo and step down from its board. And some of Dispo’s investors, including Spark Capital, Seven Seven Six and Unshackled Ventures, have also started backing away.
President Biden on Monday nominated Lina Khan to the Federal Trade Commission, installing a vocal critic of Big Tech into a key oversight role of the industry. If her nomination is approved by the Senate, Ms. Khan, 32, would fill one of two empty seats earmarked for Democrats at the F.T.C. Ms. Khan became recognized for her ideas on antitrust with a Yale Law Journal paper in 2017 called “Amazon’s Antitrust Paradox” that accused Amazon of abusing its monopoly power.
Proponents of fully reopening schools got a major boost when the Centers for Disease Control and Prevention announced that elementary school students and some middle and high school students could be spaced three feet apart in classrooms.
The previous guidance of keeping most students six feet apart had in many school districts become a big obstacle to welcoming students back for full-time instruction because it severely limited capacity. Many experts now say a growing body of research shows that six feet is not much more protective than three, as long as other safety measures are in place, like mask wearing.
Public health experts, parents and school officials cheered the new recommendation. Teachers’ unions, which have used the six-foot guidance to oppose bringing children back for normal schedules, did not.
Randi Weingarten, president of the American Federation of Teachers, the nation’s second-largest educators’ union, said in a statement that she would “reserve judgment” on the new guidelines pending further review of research on how the virus behaves in schools, especially those in cities or that are under-resourced. Becky Pringle, president of the largest teachers’ union, the National Education Association, raised similar concerns.
for example, is planning to reopen elementary schools in the coming weeks on a half-day schedule that would avoid meal times, giving students less than three hours per day of in-person schooling, only four days per week.
Meanwhile, some districts have kept schools closed one day a week for what is sometimes described as a day of “deep cleaning,” a practice that experts have said has no benefit. In Anne Arundel County, the cleaning day is why the district is aiming to bring students back four days a week this spring, rather than five.
