The universe’s clock might have bigger ticks than we imagine

0

The smallest conceivable length of time might be no larger than a millionth of a billionth of a billionth of a billionth of a second. That’s according to a new theory describing the implications of the universe having a fundamental clock-like property whose ticks would interact with our best atomic timepieces. 

Such an idea could help scientists get closer to doing experiments that would illuminate a theory of everything, an overarching framework that would reconcile the two pillars of 20th-century physics — quantum mechanics, which looks at the smallest objects in existence, and Albert Einstein’s relativity, which describes the most massive ones.

‘It’s not enough’: Activists say Black Lives Matter murals are empty gesture

0

More than a dozen other cities have since adopted the practice. New York City Mayor Bill de Blasio was one of the first to follow suit, ordering Black Lives Matter to be painted on 5th Avenue, directly across from Trump Tower. Rev. Al Sharpton and members of the Central Park Five participated in its unveiling.

Still, activists say that in most places, political leaders have not matched those expressions of support with the kinds of policy changes that would tangibly improve people’s lives. As coronavirus cases continue to spike, Black and Latino patients comprise the majority of cases and deaths. Since Floyd’s killing in late May, more African-Americans have been killed by police officers, only further injecting energy into the protest movement against police violence.

State and national legislative leaders, meanwhile, have not responded with the kind of urgency the colliding crises demand. Congress has not passed a relief package since May while more than 30 million Americans could be without any income if unemployment relief is not renewed by the end of July. A rent crisis remains on the horizon as more than one-third of Americans missed rent and mortgage payments at the beginning of the month. Black and Latino populations stand to bear the brunt of these calamities, as unemployment remains disproportionately high in both communities.

Those realities prompted D.C. activists to immediately paint a counter-message on the street next to Mayor Bowser’s Black Lives Matter mural: “Defund the police.” Black Lives Matter D.C. has also since released a statement condemning the mural and calling it “performative.”

“The folks who painted that…they know very well that that wasn’t a genuine thing by Muriel Bowser,” said Sean Blackmon, an organizer with the D.C.-based Stop Police Terror Project, which organizes nationwide against police violence. “And so what that really says is, ‘if you think that Black Lives Matter, Muriel Bowser, then you must defund the police.’”

“They paint the letters of your movement on a street and are hailed across the country but they’re not willing to look you in the eye and talk about solutions,” said Jessica Byrd, co-founder of Three Point Strategies and an organizer with the Movement for Black Lives. “I mean, it takes an incredible amount of cognitive dissonance to believe that a mural is enough and that it could replace a conversation about structural change in the city.”

In some municipalities, leaders have answered the protesters’ calls for change. Minneapolis, the catalyst for the wave of anti-racism protests happening around the world, advanced a ballot measure that would disband the city’s police department and establish a new security and violence prevention force. So far, it is the only city to pass legislation disbanding police since Floyd’s death.

But with pressure rising from local organizers and the national outcry, a growing number of state and local leaders have announced plans to decrease police budgets for the upcoming fiscal year and redirect the funds to communities of color. Los Angeles’ city council cut $150 million from its police budget. San Francisco has enacted similar measures, pledging to cut from the city’s police budget and reallocate the funds to programs benefiting the local Black community.

Defenders of the murals say that art still has a special place in social movements, and the murals are not intended to be a substitute for policy changes. Some protesters have, themselves, erected Black Lives Matter art of their own. It’s a different dynamic, however, Pierre explained, because there is a unique understanding behind the work.

“I think when activists go out, and they create those symbols, and they’ve been doing the work of really trying to uplift black people in their communities, it’s way different. Because they’re coming from the perspective of love. And it’s kind of a sign of what’s to come,” she said. “We can’t stop at paintings. We have to really change the system, especially the way that black people and the police interact.”

The Black Lives Matter movement has changed the country and shifted conversations about police, social justice and structural racism.

Nowhere is the impact as great as it is for Black families, especially those with children. NPR spoke with five couples about how their family conversations have changed and how they try to support and inform their children in the face of police violence and racism.

The parents spoke about how painful it is to have these issues rupture the innocence of childhood, and the importance of having these discussion proactively. They say they try to model a measured optimism about the future, teaching their kids “to stand up and speak out”, as one mother, Dr. Rhea Roper Nedd puts it.

She says she and her husband’s message to their children right now is hopeful, despite their own misgivings about the slow pace of progress. “This is the time for us to move forward,” she says. “This is the time to change.”

‘Exercise your right to say what you think’

When Chris and Eriade Williams decided to take their children to participate in peaceful protests near their home in Silver Spring, Md., their daughter Marley, 9, told them she was scared. Eriade, an attorney and lobbyist, had to explain that violence wouldn’t be likely. Chris, who works in pharmaceutical sales, talked to both the kids — their son Hunter is 6 — about managing fear. And he told them: “These are things that we’re protesting because they’ve never been dealt with appropriately in the past.”

Marley remained skeptical, telling her parents she was afraid there would be violence or police brutality. Her parents told her, “You still have to exercise your right to say what you think about things and you can’t be scared and stay in your house,” recalls Eriade.

The protest turned out to be a positive, empowering experience for the children. There was no violence. Marley was interviewed by local TV and even made up a dance to go with a chant. “When they came home they were exuberant,” says Eriade.

The Williams say they have a sense of relief that, after George Floyd’s brutal killing, the whole nation began discussing police violence and racism. It means, they said, that as parents “we are the ones who can explain all this to our kids and that their friends in school will have a similar baseline of experience now to understand these issues better.”

When to have ‘the talk’

As Black parents, Derek and Barbara Ford knew they would have to have “the talk” about racism at some point with their sons. Chandler, who is nearly 1-year-old, is too young to understand. And for Alexander who turns 5 this month, the Fords hadn’t thought of starting at such an early age. But as the Black Lives Matter protests took off in late May, they realized it was time.

Derek, a human resources manager in the oil and gas industry, says they didn’t try to tackle the whole topic at once. “We talk about certain aspects that he can comprehend at this point. And then through the years, that conversation morphs” he says. They have started with storytelling and books that portray individuals with brown skin so the children will “feel comfortable in their own skin” and have a positive image of themselves.

In the future, they’ll have to tackle harder issues head-on. “I mean you have to have hope, but you also have the reality that he will become a Black man; right now, he sees police officers and cops as superheroes.” Derek says. “It’s a shame that this frame of mind will likely change over time to where he no longer sees public servants as superheroes, but he sees them as something else.”

They try to strike a balance, Barbara says, between exposing their children to the reality of racism while instilling confidence in them as individuals. “We grew up and understood that everything in life wasn’t going to be fair; so we want to raise the children with a sense of reality, but we don’t want to poison them and we don’t want them to be blindsided by anything either.”

Preparing children for the future

When Maryam Jernigan-Noesi and Mariano Noesi were expecting their first child, they recall playing a trivia game at their baby shower. They were asked what they feared most about becoming new parents.

They answered without hesitation. “We were both on the same page and it was ‘the world,'” says Mariano, a national accounts manager for an environmental firm. “It was the systems created outside of our homes that were not made for him, although he’d be forced to live in them for now.”

Along with the joy of having a child, says Maryam, a licensed psychologist specializing in children and adolescents, “there is an intergenerational fear about your ability to protect Black children and help keep them alive because of the pervasiveness and, frankly, the danger of racism.”

The family lives in a suburb of Atlanta. Today, when they talk with their son Carter, now 4, about racism, a major goal, Mariano says, is “reducing the amount of trauma that I pass on to him. Reducing it being key because some trauma is inevitable in the life of a Black person in this country.”

Their approach, says Maryam, is to start with an understanding of racial differences.”We want him to first notice and appreciate human differences, not avoid or condemn what is different,” she says.

From there, they are gradually introducing the history of racial injustice and the civil rights movement.

“The key is to be consistent and proactive and to not wait until there is a blatant example that we are trying to explain after the fact,” says Maryam. She also gives her son room to express his feelings, like when she first explained the history of segregation to him and “he was visibly upset.”

She says these early lessons paid off when he saw some footage of protests on TV and wanted to know what was going on. ” And I said, well, remember Martin Luther King? You know, we’re still fighting for people to be able to be treated equally.”

‘It’s up to the next generation’

After George Floyd’s killing, the Roper Nedd family who live in Silver Spring, Md., a suburb of Washington, D.C. went into “protective mode” toward their two sons, Christopher and Noah, says Dr. Rhea Roper Nedd, associate director of the Ronald E. McNair Post-Baccalaureate Achievement Program at the University of Maryland.

“We didn’t want them to see this on TV and to internalize this,” she recalls. “But then there came a point in time when we knew … as much as we tried to protect them … we had to start talking about it.”

Husband Wilton Nedd II, an attorney, says it’s imperative “for us to instill in our children that they are equal to their white counterparts in every respect but they may not be viewed that way by everyone they encounter.”

They want their children to feel proud of who they are. They watch movies with strong Black characters, they enjoy and “move to hip-hop, soca, afro-beats, gospel music and Chelsey Green’s violin.”

“Conversations about race within the four walls of our home are intentional messages about the beauty of blackness,” says Rhea.

Rhea Roper Nedd says she and her husband teach their sons Christopher (left) and Noah to recognize the importance of changing narratives in society and recognizing that change is possible.

She says they have worked to balance realism and hope in their conversations about racial justice. When they went as a family to one of the recent protests, one of their sons questioned why they were bothering when violence against Black people keeps getting repeated.

“It’s hard to hear a young child at the age of ten already aware of the history of this country, of how racism has been institutionalized, and to already know that the change that is happening, it’s so slow,” Rhea says.

But she said they told their kids, “Things are changing. There is something about the movement and we have to be part of it.”

During the protests and candlelight vigils the family attended, Wilton told his sons that as they grow up, they have a role to play “in changing narratives and outcomes in society.”

“Our generation has made incremental progress but it is up to the next generation to take it even further,” he says.

‘We’re not walking alone’

Both Albert and Quinetta Latham remember when their own parents had “the talk” with them years ago. And while some of the nuances have changed, Albert, a regional asset protection director for a national retailer says, the conversations they’re having with their own children, Albert III, 18, and Maria, 12, are, unfortunately, familiar.

But Quinetta, a certified life coach and transformational speaker, says the Black Lives Matter movement has given the family a sense of hope. “While our 12 year old daughter might not necessarily be able to wrap her entire mind around systematic racism, both she and our son realize and understand the power and the pain that is attached to the three words Black Lives Matter.”

The support for the movement is “very visible for our children to see” she says, whether it’s on the news, hashtags, t-shirts, or TikTok. Albert says in the movement today he sees more allies of all races.

“We’re not walking alone,” Albert says. “And while these occurrences and conversations aren’t necessarily new for our household I do realize… George Floyd’s untimely and unfortunate death was certainly a tipping point for the nation.”

But seeing repeated examples of police brutality weighs on their children, the Latham parents say. And even when they went out to protest recently, the family encountered racism and profanity from people passing by. One man in a truck deliberately blew his exhaust into the crowd. “My children looked at me in disbelief,” recalls Quinetta. “We’re out here trying to stand up for what’s right and here’s what we’re still having to face.”

“So you know, it’s hard not to see it, it’s hard not to experience it, and it’s almost impossible not to fear it,” she says. “For us as parents, it’s important to just create a safe haven, a safe space for our children to feel they’re accepted when the world rejects them. A place where they can come and be lifted when the world knocks them down.”

And, when talking to their children, Albert says,”we’ve got to be very careful to not preach doom and gloom all the time — to not talk about the history of Black folk as starting in slavery or in the Jim Crow south; our history is much, much richer than the misfortunes that we faced.”

“And so another way that we try to reduce the stress for us and our children is to make sure that we understand there’s still greatness that courses through our veins.”

See Jupiter and Saturn at their brightest this week

0

Planets are very much in the fore these days, especially with the two largest — Jupiter and Saturn — now putting on a show as prominent evening luminaries. This week, both planets appear at their very best, with Jupiter having just arrived at opposition this past Tuesday (July 14) and Saturn to reach its own opposition on Monday (July 20). 

On Dec. 21, these two planets will be in conjunction — meaning they’ll share the same celestial longitude while making a close approach in the night sky — for the first time since the year 2000. It takes Saturn almost 30 years to make one trip around the sun, while it only takes Jupiter about 12 years to complete one solar revolution. As a result, Jupiter appears to overhaul Saturn at intervals of roughly 20 years.

Physicists discover new, exotic flavor of tetraquark

0

The LHCb collaboration at CERN has announced the discovery of a new exotic particle: a so-called “tetraquark.” The paper by more than 800 authors is yet to be evaluated by other scientists in a process called “peer review,” but has been presented at a seminar. It also meets the usual statistical threshold for claiming the discovery of a new particle.

The finding marks a major breakthrough in a search of almost 20 years, carried out in particle physics labs all over the world.

The Week in Business: Twitter’s Mystery Hackers

0

Good morning. A financial tip: When someone on the internet asks for Bitcoin and promises double your money back, it’s probably a lie. Here’s what else you need to know in business and tech news for the week ahead.

In perhaps the most brazen cyberattack in history, hackers commandeered dozens of Twitter’s most high-profile accounts on Wednesday afternoon — including those of Joe Biden, Barack Obama, Kim Kardashian, Kanye West, Bill Gates and Elon Musk. But what could have provoked international havoc turned out to be a relatively benign scam. (The hackers made off with over $100,000 in Bitcoin from gullible Twitter users.) The platform was re-secured after partially shutting down for several hours. Now the company and the Federal Bureau of Investigation are trying to learn who the hackers are, how much information they gained access to and what they could do with it. Then there’s the question of whether they’ll strike again — with far more damaging results.

Government data shows that businesses in Black communities were disproportionately less likely to receive loans under the Paycheck Protection Program than those in predominantly white areas. And a new study confirms what you might expect — that the disparity was at least partly the result of discrimination. When Black and white “mystery shoppers” with similar qualifications sought the relief loans from multiple branches of 17 different banks, Black customers had a harder time getting aid than their white counterparts. Separately, Senate Democrats have proposed a $350 billion package to boost economic growth in Black and other minority communities over the next five years, funded partly by unspent money from the Federal Reserve’s emergency lending programs.

It’s hard to believe that masks are still being politicized after health officials have deemed them a “critical tool” to prevent the spread of coronavirus, but here we are. While state and local officials battle over mask mandates (particularly in Georgia, Louisiana and Texas), businesses are making their own rules. Starting Monday, customers at Walmart, the country’s largest retailer and private-sector employer, will be required to wear masks in all of its stores, regardless of state regulations. Business groups view the move as a major statement about the importance of wearing masks if retailers are to operate safely. Walmart joins Apple, Kroger, Best Buy and Starbucks in requiring masks for entry, and Target and CVS quickly followed suit.

A coalition of labor unions and racial justice groups have planned a mass walkout from work on Monday to protest systemic racism and police brutality. The Strike for Black Lives is expected to include tens of thousands of workers in industries ranging from fast food to nursing homes, spread across at least 25 American cities. Those who can’t strike for the full workday will walk out for about eight minutes — the amount of time a white Minneapolis police officer held his knee on George Floyd’s neck — in remembrance of Black men and women who have died in police custody.

The United States continued to break its own records for new coronavirus cases for the third week in a row, and the economic fallout ensued. A weekly census survey showed 1.3 million fewer Americans held jobs last week than the previous one. Other recent data showed that business activity plunged in the second week of July. And jobless claims are spiking in Florida, California and Georgia, where virus cases are surging. The report for retail sales in June was rosy, but that was before the virus roared back.

Three of the country’s biggest banks — JPMorgan Chase, Citigroup and Wells Fargo — announced last week that they had squirreled away billions of dollars since March to cover potential losses on loans. Collectively, they’ve put aside over $25 billion in cash, signaling that they expect consumers and corporations to default on their debts in the coming months as the pandemic continues to gut the economy. Holding onto cash instead of investing or lending it is usually a losing business proposition for banks, and this time was no exception — all three companies saw their quarterly profits plunge. It was Wells Fargo’s first quarterly loss since 2008, and reflects a gloomy forecast for the country’s recovery.

Belgian PM Wilmès: Now is not the time for regrets on coronavirus response

0

Prime minister defends the country’s response, saying that time for regrets will come later.

There “certainly” will be regrets about how Belgium responded to the coronavirus pandemic, Prime Minister Sophie Wilmès said, “but not yet.”

Wilmès told RTBF that everyone involved in the response acted “with the knowledge and the means that we had.” 

The prime minister said the time would come for a calm analysis of how the situation in care homes was dealt with. However, she denied that the sector had been sacrificed, saying that staff at these homes did their best. Asked whether Belgium should have had more preventative policies in place, Wilmès said the answer to that would come from further analysis, but added that the matter was not within federal jurisdiction. 

As for whether priority had been given to the economy at the expense of other areas, Wilmès denied this, saying that even with limited restrictions, the economy was “struggling to restart.” 

Earlier this month, Belgian Health Minister Maggie De Block wrote in POLITICO: “Although we secured sufficient respirators and personal protection equipment for hospital staff, we did not manage to provide enough protective gear for our caregivers in the nursing homes on time. As in many other countries, this resulted in a high proportion of elderly people among our COVID-19 victims. These are human tragedies we should seriously investigate and learn from.”

However, she added that “Belgium was definitely not the worst country in its response to the pandemic.”

Today, the prime minister is chairing a meeting on the country’s rising number of coronavirus cases. Based on the outcome of the discussion, a meeting of the Belgian national security council could be convened earlier than its planned meeting on Thursday.

She wrote, “I was called a gold digger ..I kept quiet, I was called a murderer…I kept quiet, I was slut shamed…I kept quiet. [sic]”

Rhea further alleged that she was also being threatened with rape and death threats. “But how does my silence give you the right to tell me that you will get me RAPED and MURDERED if I don’t commit suicide @mannu_raaut?”

“Do you realize the seriousness of what you have said? These are crimes, and by law no one, I repeat NO ONE should be subjected to this kind of toxicity and harassment. [sic]”

She also requested the cybercrime branch India to take necessary action, saying, “ENOUGH IS ENOUGH.”

Man in custody after Nantes cathedral fire: French media

A 39-year-old man has been arrested in connection with a fire in the 15th-century cathedral in the French city of Nantes that blew out stained glass windows and destroyed the grand organ.

The man, a Rwandan refugee, worked as a volunteer for the cathedral and had been in charge of locking up the building on Friday night, TV channel LCI reported on Sunday, citing a prosecutor.

Prosecutor Pierre Sennes said the man in custody was being held to clear up inconsistencies in his schedule.

He said three fires were reported at the site and there had been no signs of a break-in. Authorities said an investigation for suspected arson had been opened.

The blaze began on Saturday morning, engulfing the inside of the Gothic structure in flames.

The fire destroyed stained glass windows and the 17th-century grand organ – a star attraction of the cathedral.

Firefighters brought it under control after several hours and extinguished it completely by the afternoon.

It happened about a year after a fire at the Notre-Dame Cathedral in Paris which destroyed its roof and main spire.

The building was last hit by fire in 1972 and its roof took more than 13 years to repair.

Regional fire chief Laurent Ferlay said on Saturday the damage was not comparable to the 1972 blaze, or to last year’s devastating blaze at the Notre-Dame cathedral.

Much of Notre-Dame’s roof and the wooden structure was destroyed, its steeple collapsed and fumes containing toxic molten lead billowed into the air.
