Although there might be other factors at work, the researchers say the stimulus checks and increased unemployment benefits shored up confidence in the economy enough that millions felt comfortable in starting a business despite being uncertain about when the pandemic would end.

When the researchers mapped the data, they found that the ZIP codes that experienced the greatest increase in business registrations were in Black areas, particularly higher median- income Black neighborhoods.

“It feels significant that we saw this big response in neighborhoods where it doesn’t typically happen,” she said. “When you remove those gateways that have worked in some ways to limit access for certain communities, then you really do unleash potential.”

The Covax distribution plan calls for providing each country with enough vaccine doses for roughly 20 percent of the population. Only after that would countries’ health needs be considered.

Peruvians are at far higher risk right now than Ghanaians of similar age and health — and both are at far higher risk than, say, Canadians or Taiwanese. By ignoring differences in risk between countries, Covax undermines its stated aim of protecting “people most at risk and those most likely to transmit the virus.”

Need should be the principal criterion for distributing vaccines among countries, but not the only one. Before vaccines are sent, countries must be able to distribute and administer them. Vaccinations — not vaccines — are what save lives.

s the global supply of vaccines expands, vaccine manufacturers and nations expecting to have extra doses, including the United States and Britain, must decide which countries to help and how many doses to send to global organizations like Covax.But if Covax’s distribution criteria remain unresponsive to need, countries with spare doses should bypass the organization and distribute them where they will reduce deaths the most.

And I would worry about something else as well: As Hamas makes itself the vanguard of the Palestinian cause — and becomes its face — more and more progressives will come to understand what Hamas is — an Islamo-fascist movement that came to power in Gaza by a 2007 coup against the Palestinian Authority, during which, among other things, it threw a rival P.A. official off a 15-story rooftop.

This is not a “progressive” organization — and Hamas will not enjoy indefinitely the free pass it has gotten from the left because it is fighting Netanyahu

Indeed, what Kissinger began in 1973 and Jimmy Carter completed at Camp David was only possible because all these leaders actually agreed to ignore the core problem

So, my message to Biden would be this: You may be interested in China, but the Middle East is still interested in you. You deftly helped to engineer the cease-fire from the sidelines. Do you want to, do you dare to, dive into the middle of this new Kissingerian moment?

Courts have generally accepted the argument that the police need to make difficult, quick decisions while responding to perceived threats.

In Mr. Chauvin’s trial, prosecutors have argued that the defendant had ample time to change how he was subduing Mr. Floyd but did not, even after it was clear that Mr. Floyd had stopped moving.

Even when, as in the death of Mr. Floyd, much of the public views a killing as not justified and prosecutors believe they have strong evidence to prove that, the outcome is far from certain.

China, the world’s largest emitter of greenhouse gases, has pledged that its emissions will peak by around 2030. From that point, the country will then aim to get down to net zero emissions by 2060.

Partly for that reason, some environmentalists have argued that the United States should have picked an even more ambitious target for reducing emissions.

Many Republicans in Congress have argued that the Biden administration is acting too aggressively on climate change when countries like China and India have yet to commit to absolute emissions cuts. Senator John Barrasso, Republican of Wyoming, said that the president was “unilaterally committing America to a drastic and damaging emissions pledge” that would punish the U.S. economy while “America’s adversaries like China and Russia continue to increase emissions at will.”

So far, the results have been mixed. Japan and Canada both agreed to strengthen their 2030 targets. The British government said Tuesday that it would step up action with a new target, cutting emissions 78 percent below 1990 levels by 2035. But other major emitters such as China, India and Russia have yet to offer significant new pledges.

To get at least a 50 percent cut by 2030, a variety of studies have found, the United States would need to adopt sweeping new policies and slash emissions each year at an unprecedented rate. Possible strategies include requiring utilities to install vastly more wind and solar power, persuading Americans to buy many more electric cars, and forcing oil and gas companies to slash emissions of methane, a potent heat-trapping gas. States like California and New York could help, too, by following through on their plans to clean up their power plants and vehicle fleets.

“In countries where a change in government can derail the whole thing,” said Oliver Geden, a senior fellow at the German Institute for International and Security Affairs, “it’s a lot harder to be sure that these goals are here to stay.”

In 2014, Officer Jason Shuck shot a man who ran away from the police when they approached him as he was panhandling outside a Walmart in Springfield, Mo. Officer Shuck later told an investigator his “brain was saying Taser” but his “body moved faster” and he drew his pistol.Local prosecutors allowed the officer to plead guilty to a misdemeanor assault charge. As part of the plea deal, Mr. Shuck, who quit the police department, agreed to never work again in a job that required him to carry a firearm.

Mr. Weisberg said that cases in which officers say they mistook which weapon they were using are rare. He said they are legally different from the majority of police shootings, where officers concede they used deadly force but argue they were justified in doing so.

In 2019, Matthew D. Weintraub, the district attorney in Bucks County, Penn., investigated a case of weapon confusion involving an officer who yelled, “Taser!” before shooting a man in a police holding cell. Mr. Weintraub ultimately ruled out charges after finding that the shooting was “neither justified, nor criminal” and that the officer had an “honest but mistaken” belief that he had used his Taser against the victim, who was injured but survived.

Mr. Orloff said that had prosecutors known Mr. Mehserle was going to make that argument before charging him, “it would have made it more likely that a manslaughter charge was filed as opposed to a murder charge.” Mr. Mehserle was convicted of involuntary manslaughter.Mike Rains, a lawyer in California who represents law enforcement in criminal and civil cases, including Mr. Mehserle, said officers mistake firearms for stun guns because they are on “autopilot,” and the officers should not be held criminally culpable.He said many officers in such cases have been trained to draw the stun gun with the same hand as their firearm. He said they typically have fired only one shot with the firearm, indicating a mistake — if they intended to use the firearm, he said, they would likely have fired multiple shots.

he mayor of Virginia Beach, Robert M. Dyer, said the 2019 shooting and the coronavirus pandemic prompted the city to come together, and he expected that to happen after the shootings on Friday night. “We’re a very resilient city,” he said.

Where elephants disappear, they leave a big gap — not just physically, but also in the work they do. Some tree species depend entirely on forest elephants to eat their fruits, swallow their large seeds and deposit them elsewhere in a pile of dung.

Savanna elephants are “thriving,” Dr. Okita said, in the Kavango Zambezi Transfrontier Conservation Area, which overlaps five countries in southern Africa. In some parts of Gabon and the Republic of Congo, forest elephant populations have stabilized or even grown. Where people are protecting elephants against poachers and planning land use carefully, Dr. Okita said, there has been progress.

In 2014, Ahmad’s older brother Imad pleaded guilty in Denver to carrying a concealed weapon, records show. He was arrested again four years later on a charge of possession of a weapon by a previous offender, though prosecutors did not pursue charges.In 2016, a female member of the family pleaded guilty to a charge of reckless endangerment and was given a deferred sentence after she agreed to take a parenting class.In 2018, the Arvada police responded to a call at the house that stemmed from a dispute between Imad Alissa and his wife, Ms. Archuleta’s daughter. The couple had broken up (they later reconciled, Ms. Archuleta said), and a fight over a torn mattress had escalated to the point that the police were called.

Six days before the attack, Mr. Alissa bought a Ruger AR-556 pistol, a handgun that resembles a shortened assault-style rifle, from a gun store just three miles from the family home. About two days before the attack, a relative saw him back at the family home, playing with what she told the police looked like a “machine gun.”After the attack, the Mercedes C-class sedan that was often seen parked in the driveway of the large family house was one of the cars left in the parking lot at the King Soopers grocery, along with all of the other cars whose owners would not be driving them home. An empty rifle case was left in the passenger compartment.

Reporters have learned to spend more time focusing on victims, rather than perpetrators. It was a shift that played out vocally on social media, as readers on Twitter implored news organizations to focus more on the people who were killed in the Atlanta shootings, as well as the uptick in crimes against Asian-Americans, rather than the gunman’s supposed motive.

ournalists are usually expected to set their feelings aside as they gather disinterested facts about a tragic event. But it’s not always possible, and Mr. Holt said that it was important to “report these things as unusual, as not normal.”

“I think it’s OK to be a little pissed off,” Mr. Holt, of “NBC Nightly News,” said. “As a journalist, it’s not an editorial position to be upset or angry at mass murder, of people going about their day, shopping, getting cut down by a stranger. It’s OK to be upset about that.”

“Every journalist goes through tough stories,” he said. “We are not alone with it. It’s just unfortunate that we’ve had in Colorado, a number of these, that have given us, for lack of a better term, training in how to try to deal with these things. But it’s still going to be awful.”

The study of 100 patients from 21 states, published on Tuesday in The Annals of Clinical and Translational Neurology, found that 85 percent of them experienced four or more neurological issues like brain fog, headaches, tingling, muscle pain and dizziness.

Participants in the study were overwhelmingly white, and 70 percent were women. Dr. Navis and others said that the lack of diversity quite likely reflected the demographics of people able to seek care relatively early in the pandemic rather than the full spectrum of people affected by post-Covid neurological sympto

In the Northwestern study, 43 percent of the patients had depression before having Covid-19; 16 percent had previous autoimmune diseases, the same percentage of patients who had previous lung disease or had struggled with insomnia.

“Waking up every day in this body, sometimes hope feels a little dangerous,” said Ms. Khan, who will soon start the cognitive rehab program. “I have to wonder: Am I going to recover, or am I going to just figure out how to live with my new brain?”

President Bolsonaro, who continues to promote ineffective and potentially dangerous drugs to treat the disease, has also said lockdowns are untenable in a country where so many people live in poverty. While several Brazilian states have ordered business shutdowns in recent weeks, there have been no strict lockdowns.Some of the president’s supporters in Porto Alegre have protested business shutdowns in recent days, organizing caravans that stop outside of hospitals and blast their horns while inside Covid wards overflow.

Epidemiologists say Brazil could have avoided additional lockdowns if the government had promoted the use of masks and social distancing and aggressively negotiated access to the vaccines being developed last year.

uch conspiracy theories about Covid-19 vaccines have spread widely on social media, including on WhatsApp and Facebook. A recent public opinion poll by the firm IPEC found that 46 percent of respondents believed at least one widely disseminated falsehood about vaccines.Mistrust of vaccines and science is new in Brazil and a dangerous feature of the Bolsonaro era, said Dr. Miguel Nicolelis, a Brazilian neurologist at Duke University who led a coronavirus task force in the country’s northeast last year.

The mistrust and the denials — and the caravans of Bolsonaro supporters blasting their horns outside hospitals to protest pandemic restrictions — are crushing for medical professionals who have lost colleagues to the virus and to suicide in recent months, said Claudia Franco, the president of the nurses union in Rio Grande do Sul.

He provided the deciding vote on two of the biggest liberal priorities of this era — blocking repeal of the Affordable Care Act in 2017 and on passage of the nearly $2 trillion stimulus bill this month — while also twice voting to convict an impeached president wildly popular in his home state.And while he may admire Mr. Byrd’s dedication to Senate tradition, Mr. Manchin has not emulated his predecessor by leveraging his power to focus relentlessly on steering spending projects back to West Virginia.

Mr. Manchin said President Biden warned him in a phone call that the progressive left in the House might balk if the bill were significantly trimmed. “I said, ‘Mr. President, all we’re trying to do is put some guard rails on this,’” he recalled.He was less happy about Vice President Kamala Harris’s effort to nudge him on the legislation by making an appearance on a television affiliate in West Virginia to promote the bill without forewarning him. The clip went viral and, Mr. Manchin said, prompted cleanup conversations with Mr. Biden and the White House chief of staff, Ron Klain.

Senator Rubio asked President Biden for $725 million this year to jump-start the big projects. Environmental groups like the Everglades Foundation want a four-year commitment of close to $3 billion, about equal to the Army Corps of Engineers’s estimates of what it will take to keep restoration efforts on track for the next decade. Either way, these numbers would help Washington finally honor its original pledge. They represent a low-cost but vital investment in the natural world that Mr. Biden and his environmental team should find easy to make.

Mr. Biden has pledged not to raise taxes on people earning less than $400,000.

“The purpose of the tax system is to both raise enough revenue for what the government wants to do, and to make sure that as we’re doing that we are encouraging activities that are in the national interest and discouraging ones that are not,” said Heather Boushey, a member of the White House’s Council of Economic Advisers.Key Democrats are trying to bring the party to consensus. The top tax writer in the Senate, Ron Wyden of Oregon, is drafting a series of bills to raise taxes, many of them overlapping with Mr. Biden’s campaign proposals.

A report from the congressional Joint Committee on Taxation this month showed that multinational companies paid an average U.S. tax rate of less than 8 percent on their income in 2018, down from 16 percent in 2017. The report also found that those companies did not slow their practice of booking profits in low-tax havens like Bermuda.

Approaching guns from the perspective of trauma will require some imagination — and some courage. In the days and weeks to come, we will be tempted to double down on our usual agendas and party lines. We should embrace evidence-based policies to reduce gun violence. But we can’t stop there. Addressing gun violence in the spaces where we live our lives — our grocery stores, our workplaces, our schools, our streets and our homes — requires addressing the damage gun trauma inflicts on our souls, retooling our familiar agendas, letting go of partisanship and remembering that we share a basic vulnerability as humans that can unite us or, if we choose, divide us further.

Logistical hurdles and missteps could drive slower vaccination campaigns. But states may also be falling behind because of high levels of vaccine hesitancy. If that's the case, it will take more than just opening up eligibility to get the country to levels of vaccination that can reach herd immunity — when roughly 70 percent of people are vaccinated, making it too difficult for the virus to spread.

With Virginia’s ban this week, 23 states now prohibit the death penalty, and 11 more haven’t used it in at least a decade. It’s not a simple partisan issue, either. In several states, Republican lawmakers have joined Democrats in voting to ban capital punishment. In Virginia, some Democrats still supported the practice as recently as last year.

President Biden, who like most Democratic presidential candidates campaigned on ending the death penalty, can help break that cycle by imposing an immediate moratorium on federal executions, and commuting the sentences of the 50 or so inmates on federal death row in Terre Haute, Ind. These inmates account for a small fraction of the more than 2,500 condemned people around the country, but a moratorium would still be an important step toward admitting what the country’s highest court began to acknowledge decades ago: The death penalty is cruel, ineffective and morally repugnant. America needs to join most of the rest of the world and eliminate it.

One third of Republicans surveyed in a CBS News poll said that they would avoid getting vaccinated — compared with 10 percent of Democrats — and another 20 percent of Republicans said they were unsure. Other polls found similar trends.

A new report by the Network Contagion Research Institute at Rutgers University noted, however, that although the deplatforming of extremist groups made their campaigns harder to follow, the alliance has the potential to meld disparate factions into a large anti-government movement united around public health issues.“It increases the opportunity for a big tent enemy,” said Joel Finkelstein, a fellow at Rutgers who runs the institute. “If you are feeling dispossessed, like all these right-wing groups are, boy do I have a tent for you.”Ben Decker contributed research.
