Prosecutors declined to pursue many of the cases because they concluded the protesters were exercising their basic civil rights.

An English teacher at Marion C. Moore School at that time, Mr. Kaufmann was among more than 800 people swept up by the police in Louisville during the many months of demonstrations prompted by the police killings of George Floyd in Minneapolis and Breonna Taylor in Louisville.

Now, more than five months later, as Mr. Kaufmann’s case and those of thousands of others finally land in courts across the United States, a vast majority of cases against protesters are being dismissed. Only cases involving more substantial charges like property destruction or other violence remain.

President Trump briefly left Walter Reed National Military Medical Center on Sunday evening to wave to supporters gathered outside. A masked Trump was seen waving to supporters from a black SUV. Other images showed Secret Service personnel in the vehicle with personal protective equipment on.

Some experts swiftly characterized Trump's drive-by greeting as reckless. Dr. James Phillips, chief of disaster medicine at George Washington University, lambasted the move as being made for "political theater."

"That Presidential SUV is not only bulletproof, but hermetically sealed against chemical attack. The risk of COVID-19 transmission inside is as high as it gets outside of medical procedures. The irresponsibility is astounding. My thoughts are with the Secret Service forced to play," he wrote on Twitter.

One of the most lethal leadership failures in modern times unfolded in South Africa in the early 2000s as AIDS spread there under President Thabo Mbeki.Mbeki scorned science, embraced conspiracy theories, dithered as the disease spread and rejected lifesaving treatments. His denialism cost about 330,000 lives, a Harvard study found

“We’re unfortunately in the same place,” said Anne Rimoin, an epidemiologist at U.C.L.A. “Mbeki surrounded himself with sycophants and cost his country hundreds of thousands of lives by ignoring science, and we’re suffering the same fate.”

“I see it as a colossal failure of leadership,” said Larry Brilliant, a veteran epidemiologist who helped eliminate smallpox in the 1970s. “Of the more than 200,000 people who have died as of today, I don’t think that 50,000 would have died if it hadn’t been for the incompetence.”

A study published earlier this month in PLOS One showed that some dinosaurs were particularly efficient walkers because of their long hind limbs. Thanks to their lanky legs, T. rex didn’t need to eat as much as its brethren, and could therefore get away with hunting less frequently, the team concluded.

To understand the biomechanics of long-extinct animals, scientists rely on fossilized bones and footprints. These records reveal information about a creature’s bone and muscle structure and its stride, all of which affect its ability to run. But identifying who is fleet of foot solely from imprints or a pile of bones is challenging.

In 1976, Robert McNeill Alexander, a British zoologist, proposed that a dinosaur’s maximum running speed depended on its stride length and hip height. But that idea has been revised over time.

here are questions as to whether the leftward shift seen in the polls “is short-term or reflects a long-term trend.” Whites’ racial attitudes, Banks wrote:are fairly stable. Once their attitudes are crystallized, they tend not to change. It would take a shifting of racial norms to change the country’s (e.g. whites’) views about policing and the black community.” He added that “much more would need to be done from both political parties and activists to cause a major change in the politics of race.

White Americans have a history of losing interest in racial justice soon after they acknowledge injustice, as if their acknowledgment, rather than actual changes in the world, was the end of the matter. We saw as the Sixties progressed, many whites who were appalled by dogs attacking black children eventually lost patience with demands for greater economic equality for blacks and resisted changes in their own communities.

He warned that “this is a moment when it’s especially dangerous to misunderstand what public opinion surveys tell us.”The fundamental analytical danger is to believe that the result of opinion polling matters in any straightforward way. That’s not how America works, otherwise we would have had stricter gun control after Parkland, etc. The actual question is not whether a majority of Americans say they want X on a survey, but whether enough Americans care enough about X in their lives to overcome the resistance and resources of those who benefit from/believe in X as well as a system of government that puts up enormous procedural barriers against the kinds of X’s we are talking about.

Less than half of Republicans believe that COVID-19 is a major threat to public health. 63 percent of Republicans say that the extent of the coronavirus is exaggerated. A quarter of the public thinks that the pandemic is the result of a planned conspiracy.

40 percent of Republicans say COVID-19 is no more deadly than the flu. 50 percent of Republicans say the COVID-19 death toll is an exaggeration. 23 percent of Republicans say masks should be worn "rarely" or "never."

Six QAnon believers have won Republican primaries this cycle. One of them, Marjorie Taylor Greene, has been warmly embraced by both Republican House leadership and President Trump. There's Donald Trump's victory in 2016 over a bevy of actual conservatives, including Ted Cruz, Rick Santorum, Carly Fiorina, Chris Christie, Jeb Bush, Bobby Jindal, Scott Walker, Mike Huckabee, and Rick Perry. There's this little nugget of Republican primary preferences for 2024, where Donald Trump Jr. was in second place and polling at 17 percent. Which is—let's just be honest here—bonkers unless you view the party as a cult.

The now-prophetic words could be found at the end of a research paper published in the journal Clinical Microbiology Reviews in October of 2007: “The presence of a large reservoir of SARS-CoV-like viruses in horseshoe bats, together with the culture of eating exotic mammals in southern China, is a time bomb.”

The warning—made nearly 13 years ago and more than four years after the worrying first wave of severe acute respiratory syndrome, or SARS, killed nearly 800 people globally—was among the earliest to predict the emergence of something like SARS-CoV-2, the virus behind the current COVID-19 pandemic.

Allen recently read a study published in The New England Journal of Medicine that found female primary care physicians spend more time with their patients than male doctors — an average of 2.4 minutes per visit, to be specific. But female physicians still make less money

"The pay gap in medicine by gender is very well documented," Neprash says. "It's been written about for decades, but the understanding of what exactly drives that is pretty sparse."

The study's authors analyzed data from over 24 million primary care visits in 2017, digging deep into information from Athenahealth, an electronic medical records company that's widely used in primary care practices.

Yglesias explained why pushing back against the “dominant sensibility” in digital journalism is important to him. He said he believes that certain voguish positions are substantively wrong—for instance, abolishing or defunding police—and that such arguments, as well as rhetorical fights over terms like Latinx, alienate many people from progressive politics and the Democratic Party.

there’s a dynamic where there’s media people who really elevated the profile of [Alexandria Ocasio-Cortez] and a couple of other members way above their actual numerical standing.”

“The people making the media are young college graduates in big cities, and that kind of politics makes a lot of sense to them,” he said. “And we keep seeing that older people, and working-class people of all races and ethnicities, just don’t share that entire worldview. It’s important to me to be in a position to step outside that dynamic …

“Thirty-two percent of teen girls said that when they felt bad about their bodies, Instagram made them feel worse,” the researchers said in a March 2020 slide presentation posted to Facebook’s internal message board, reviewed by The Wall Street Journal. “Comparisons on Instagram can change how young women view and describe themselves.”

For the past three years, Facebook has been conducting studies into how its photo-sharing app affects its millions of young users. Repeatedly, the company’s researchers found that Instagram is harmful for a sizable percentage of them, most notably teenage girls.

“We make body image issues worse for one in three teen girls,” said one slide from 2019, summarizing research about teen girls who experience the issues.

The world needs to address the root causes of vaccine hesitancy. We can’t go on believing that the issue can be solved simply by flooding skeptical communities with public service announcements or hectoring people to “believe in science.”

For the past five years, we’ve conducted surveys and focus groups abroad and interviewed residents of the Bronx to better understand vaccine avoidance.

We’ve found that people who reject vaccines are not necessarily less scientifically literate or less well-informed than those who don’t. Instead, hesitancy reflects a transformation of our core beliefs about what we owe one another.

If heat waves were as deadly as the press proclaims, Homo sapiens couldn’t have survived thousands of years without air conditioning. Yet here we are

Humans have shown remarkable resilience and adaptation—at least until modern times, when half of society lost its cool over climate change.

it’s alarmist stories about bad weather that are fueling mental derangements worthy of the DSM-5—not the warm summer air itself.

While Florida was an early leader in the share of over-65 residents who were vaccinated, it had fallen to the middle of the pack by the end of July 2021. When it came to younger residents, Florida lagged behind the national average in every age group.

That left the state particularly vulnerable when the Delta variant hit that month. Floridians died at a higher rate, adjusted for age, than residents of almost any other state during the Delta wave, according to the Times analysis. With less than 7 percent of the nation’s population, Florida accounted for 14 percent of deaths between the start of July and the end of October.

Of the 23,000 Floridians who died, 9,000 were younger than 65. Despite the governor’s insistence at the time that “our entire vulnerable population has basically been vaccinated,” a vast majority of the 23,000 were either unvaccinated or had not yet completed the two-dose regimen.

ChatGPT is built atop a so-called large language model—powerful software trained on swaths of text scraped from across the internet to learn the patterns of human language. The vast data supercharges its capabilities, allowing it to act like an autocompletion engine on steroids. The training also creates a hazard. Given the right prompts, a large language model can generate reams of toxic content inspired by the darkest parts of the internet.

ChatGPT’s parent, AI research company OpenAI, has been grappling with these issues for years. Even before it created ChatGPT, it hired workers in Kenya to review and categorize thousands of graphic text passages obtained online and generated by AI itself. Many of the passages contained descriptions of violence, harassment, self-harm, rape, child sexual abuse and bestiality, documents reviewed by The Wall Street Journal show.

The company used the categorized passages to build an AI safety filter that it would ultimately deploy to constrain ChatGPT from exposing its tens of millions of users to similar content.

In an academic career that included more than two decades as a professor in the philosophy department of the University of Toronto, following appointments at Cambridge and Stanford, Professor Hacking’s intellectual scope seemed to know no bounds. Because of his ability to span multiple academic fields, he was often described as a bridge builder.

“Ian Hacking was a one-person interdisciplinary department all by himself,” Cheryl Misak, a philosophy professor at the University of Toronto, said in a phone interview. “Anthropologists, sociologists, historians and psychologists, as well as those working on probability theory and physics, took him to have important insights for their disciplines.”

Professor Hacking wrote several landmark works on the philosophy and history of probability, including “The Taming of Chance” (1990), which was named one of the best 100 nonfiction books of the 20th century by the Modern Library.

Jonathan Clarke, writing in the Manhattan Institute’s City Journal, of which he is a contributing editor, said the “democratization of dress” in recent decades has produced “the rapid casualization of American life.” But this has calcified into an unattractive norm

Is there a more obvious contemporary ostentation than tech billionaires conducting business wearing T-shirts to advertise that they are too rich to have sartorial concerns?

Clarke, who confesses a “slightly antique sense of propriety,” writes “few things are more heartening than to see a man or woman of advanced age very well dressed.

But none of that is enough, practically speaking, because of one enormous hitch: The world is still using more energy each year, our consumption ticking ever upward, swallowing any gains made by renewable energy. Emissions are still rising—more slowly than they used to but, nonetheless, rising. Instead of getting pushed down, that needle is fitfully jiggling above zero, clawing into the positive digits when it needs to be deeply pitched into the negative. We are, in other words, simply not making a dent.

And so we are now in climate purgatory. In this zone, countries and companies are doing the right things to steer away from the damages of climate change, but are at the very same time making deliberate choices that swamp the effect of those other, better things.

governments in aggregate still plan to increase coal production until 2030, and oil and gas production until at least 2050, global net-zero agreements be damned. In total, countries that hold the world’s oil, gas, and coal deposits still plan to produce 69 percent more fossil fuels than is compatible with keeping warming under 2 degrees Celsius

Andrew Bryant can still remember when he thought of climate change as primarily a problem of the future. When he heard or read about troubling impacts, he found himself setting them in 2080, a year that, not so coincidentally, would be a century after his own birth. The changing climate, and all the challenges it would bring, were “scary and sad,” he said recently, “but so far in the future that I’d be safe.”

That was back when things were different, in the long-ago world of 2014 or so. The Pacific Northwest, where Bryant is a clinical social worker and psychotherapist treating patients in private practice in Seattle, is a largely affluent place that was once considered a potential refuge from climate disruption

“We’re lucky to be buffered by wealth and location,” Bryant said. “We are lucky to have the opportunity to look away.”
