Researchers from UEA's Norwich Medical School said a study of 20 members of the group over six months found singing and mixing socially had helped those who had had serious mental health issues to function better in day-to-day life.

"Anyone can make a noise. No-one is ever rejected in these groups.

They communicated without knowing the same language but as my mother learned English, she had a very heavy accent and still does to this day at the age of 91.

There are children in every classroom learning a language — whether it's English or not. Everywhere in the world with refugees dispersed, people are learning new languages and adapting to new homes.

As we mature and then go to school and encounter people from all different backgrounds, it's kind of a shock for anybody in any language to seek a sense of belonging with people who aren't from your family, people you don't know. And yet there are these universal languages, like poetry, which is musical and is rooted in emotions. And I feel like that's a refuge.

For me, when I think of where have I ever had a sense of belonging, I have a sense of belonging on the page.

Way added that there might be other reasons why newborns should carry immunosuppressive cells

Baby formulas contain small amounts of arginine. Sidney Morris, a biochemist from the University of Pittsburgh, said that it may be important to avoid fortifying them with extra arginine, lest it swamps the arginase activity of CD71+ cells, releases the immune system, and causes problems for the developing infants’ guts.

“Whether the precise mechanism of immunosuppression is the same or different in each of these circumstances remains to be determined,” he said.

In short, a complex and evolving system — whether that’s a flock of gold finches or a nebula or the English language — will produce ever more diverse and intricately detailed states and configurations of itself.

Some of these more diverse and intricate configurations, the scientists write, are shed and forgotten over time. The configurations that persist are ones that find some utility or novel function in a process akin to natural selection, but a selection process driven by the passing-on of information rather than just the sowing of biological genes

Have they finally glimpsed, I wonder, the connectedness and symbiotic co-evolution of their own scientific ideas with those of the world’s writers

Have they learned to describe in their own quantifying language that cradle from which both our disciplines have emerged and the firmament on which they both stand — the hearing and telling of stories in order to exist?

Have they quantified the quality of all existent matter, living and not: that all things inherit a story in data to tell, and that our stories are told by the very forms we take to tell them? 

“Is there a universal basis for selection? Is there a more quantitative formalism underlying this conjectured conceptual equivalence—a formalism rooted in the transfer of information?,” they ask of the world’s disparate phenomena. “The answer to both questions is yes.”

Yes. They’ve glimpsed it, whether they know it or not. Sing to me, O Muse, of functional information and its complex diversity.

The principle of complexity evolving at its own pace when left to its own devices, independent of time but certainly in a dance with it, is nothing new. Not in science, nor in its closest humanities kin, science and nature writing. Give things time and nourishing environs, protect them from your own intrusions and — living organisms or not — they will produce abundant enlacement of forms.

This is how poetry was born from the same larynxes and phalanges that tendered nuclear equations: We featherless bipeds gave language our time and delighted attendance until its forms were so multivariate that they overflowed with inevitable utility.

In her Pulitzer-winning “Pilgrim at Tinker Creek,” nature writer Annie Dillard explains plainly that evolution is the vehicle of such intricacy in the natural world, as much as it is in our own thoughts and actions. 

“The stability of simple forms is the sturdy base from which more complex, stable forms might arise, forming in turn more complex forms,” she explains, drawing on the undercap frills of mushrooms and filament-fine filtering tubes inside human kidneys to illustrate her point. 

“Utility to the creature is evolution’s only aesthetic consideration. Form follows function in the created world, so far as I know, and the creature that functions, however bizarre, survives to perpetuate its form,” writes Dillard.

“Of the multiplicity of forms, I know nothing. Except that, apparently, anything goes. This holds for forms of behavior as well as design — the mantis munching her mate, the frog wintering in mud.” 

She notes that, of all forms of life we’ve ever known to exist, only about 10% are still alive. What extravagant multiplicity. 

“Intricacy is that which is given from the beginning, the birthright, and in the intricacy is the hardiness of complexity that ensures against the failures of all life,” Dillard writes. “The wonder is — given the errant nature of freedom and the burgeoning texture of time — the wonder is that all the forms are not monsters, that there is beauty at all, grace gratuitous.”

“This paper, and the reason why I'm so proud of it, is because it really represents a connection between science and the philosophy of science that perhaps offers a new lens into why we see everything that we see in the universe,” lead scientist Michael Wong told Motherboard in a recent interview. 

Wong is an astrobiologist and planetary scientist at the Carnegie Institute for Science. In his team’s paper, that bridge toward scientific philosophy is not only preceded by a long history of literary creativity but directly theorizes about the creative act itself.  

“The creation of art and music may seem to have very little to do with the maintenance of society, but their origins may stem from the need to transmit information and create bonds among communities, and to this day, they enrich life in innumerable ways,” Wong’s team writes.  

“Perhaps, like eddies swirling off of a primary flow field, selection pressures for ancillary functions can become so distant from the core functions of their host systems that they can effectively be treated as independently evolving systems,” the authors add, pointing toward the elaborate mating dance culture observed in birds of paradise.

“Perhaps it will be humanity’s ability to learn, invent, and adopt new collective modes of being that will lead to its long-term persistence as a planetary phenomenon. In light of these considerations, we suspect that the general principles of selection and function discussed here may also apply to the evolution of symbolic and social systems.”

The Mekhilta teaches that all Ten Commandments were pronounced in a single utterance. Similarly, the Maharsha says the Torah’s 613 mitzvoth are only perceived as a plurality because we’re time-bound humans, even though they together form a singular truth which is indivisible from He who expressed it. 

Or, as the Mishna would have it, “the creations were all made in generic form, and they gradually expanded.” 

Like swirling eddies off of a primary flow field.

“O Lord, how manifold are thy works!,” cried out David in his psalm. “In wisdom hast thou made them all: the earth is full of thy riches. So is this great and wide sea, wherein are things creeping innumerable, both small and great beasts.” 

In all things, then — from poetic inventions, to rare biodiverse ecosystems, to the charted history of our interstellar equations — it is best if we conserve our world’s intellectual and physical diversity, for both the study and testimony of its immeasurable multiplicity.

Because, whether wittingly or not, science is singing the tune of the humanities. And whether expressed in algebraic logic or ancient Greek hymn, its chorus is the same throughout the universe: Be fruitful and multiply. 

Both intricate configurations of art and matter arise and fade according to their shared characteristic, long-known by students of the humanities: each have been graced with enough time to attend to the necessary affairs of their most enduring pleasures. 

Young people, who have no place in this dead-eyed, sanitized landscape, scarcely venture from their bedrooms. Political freedom now means choosing between alternative versions of market fundamentalism.

Even the freedoms we do possess we tend not to exercise. We spend hours every day watching other people doing what we might otherwise be doing: dancing, singing, playing sports, even cooking. We venture outdoors to seek marginally different varieties of stuff we already possess

We entertain the illusion that we have chosen our lives. Why, if this is the case, do our apparent choices differ so little from those of other people? Why do we live and work and travel and eat and dress and entertain ourselves in almost identical fashion? It’s no wonder, when we possess and use it so little, that we make a fetish out of freedom.Continue reading the main story

our survival in the modern economy requires the use of few of the mental and physical capacities we possess. Sometimes it feels like a small and shuffling life. Our humdrum, humiliating lives leave us, I believe, ecologically bored.

Across many rich nations, especially the United States, global competition is causing the abandonment of farming on less fertile land. Rather than trying to tame and hold back the encroaching wilds, I believe we should help to accelerate the process of reclamation, removing redundant roads and fences, helping to re-establish missing species, such as wolves and cougars and bears, building bridges between recovering habitats to create continental-scale wildlife corridors, such as those promoted by the Rewilding Institute.

This rewilding of the land permits, if we choose, a partial rewilding of our own lives. It allows us to step into a world that is not controlled and regulated, to imagine ourselves back into the rawer life from which we came

“Over 100 likes is good, for me. And comments. You just comment to make a joke or tag someone.”

The best thing is the little notification box, which means someone liked, tagged or followed her on Instagram. She has 604 followers. There are only 25 photos on her page because she deletes most of what she posts. The ones that don’t get enough likes, don’t have good enough lighting or don’t show the coolest moments in her life must be deleted.

Sociologists, advertisers, stock market analysts – everyone wants to know what happens when the generation born glued to screens has to look up and interact with the world.

“It kind of, almost, promotes you as a good person. If someone says, ‘tbh you’re nice and pretty,’ that kind of, like, validates you in the comments. Then people can look at it and say ‘Oh, she’s nice and pretty.’ ”

School is where she thrives: She is beloved by her teachers, will soon star as young Simba in the eighth-grade performance of “The Lion King” musical, and gets straight A’s. Her school doesn’t offer a math course challenging enough for her, so she takes honors algebra online through Johns Hopkins University.

“Happy birthday posts are a pretty big deal,” she says. “It really shows who cares enough to put you on their page.”

He checks the phone bill to see who she’s called and how much she’s been texting, but she barely calls anyone and chats mostly through Snapchat, where her messages disappear.

Some of Katherine’s very best friends have never been to her house, or she to theirs. To Dave, it seems like they rarely hang out, but he knows that to her, it seems like they’re together all the time.

Dave Pommerening wants to figure out how to get her to use it less. One month, she ate up 18 gigabytes of data. Most large plans max out at 10. He intervened and capped her at four GB. “I don’t want to crimp it too much,” he says. “That’s something, from my perspective, I’m going to have to figure out, how to get my arms around that.”

Even if her dad tried snooping around her apps, the true dramas of teenage girl life are not written in the comments. Like how sometimes, Katherine’s friends will borrow her phone just to un-like all the Instagram photos of girls they don’t like. Katherine can’t go back to those girls’ pages and re-like the photos because that would be stalking, which is forbidden.

Or how last week, at the middle school dance, her friends got the phone numbers of 10 boys, but then they had to delete five of them because they were seventh-graders. And before she could add the boys on Snapchat, she realized she had to change her username because it was her childhood nickname and that was totally embarrassing.

Then, because she changed her username, her Snapchat score reverted to zero. The app awards about one point for every snap you send and receive. It’s also totally embarrassing and stressful to have a low Snapchat score. So in one day, she sent enough snaps to earn 1,000 points.

Snapchat is where flirting happens. She doesn’t know anyone who has sent a naked picture to a boy, but she knows it happens with older girls, who know they have met the right guy.

Nothing her dad could find on her phone shows that for as good as Katherine is at math, basketball and singing, she wants to get better at her phone. To be one of the girls who knows what to post, how to caption it, when to like, what to comment.

Katherine doesn’t need magazines or billboards to see computer-perfect women. They’re right on her phone, all the time, in between photos of her normal-looking friends. There’s Aisha, there’s Kendall Jenner’s butt. There’s Olivia, there’s YouTube star Jenna Marbles in lingerie.

The whole world is at her fingertips and has been for years. This, Katherine offers as a theory one day, is why she doesn’t feel like she’s 13 years old at all. She’s probably, like, 16.

“I don’t feel like a child anymore” she says. “I’m not doing anything childish. At the end of sixth grade” — when all her friends got phones and downloaded Snapchat, Instagram and Twitter — “I just stopped doing everything I normally did. Playing games at recess, playing with toys, all of it, done.”

Her scooter sat in the garage, covered in dust. Her stuffed animals were passed down to Lila. The wooden playground in the back yard stood empty. She kept her skateboard with neon yellow wheels, because riding it is still cool to her friends.

On the morning of her 14th birthday, Katherine wakes up to an alarm ringing on her phone. It’s 6:30 a.m. She rolls over and shuts it off in the dark. Her grandparents, here to celebrate the end of her first year of teenagehood, are sleeping in the guest room down the hall. She can hear the dogs shuffling across the hardwood downstairs, waiting to be fed. Propping herself up on her peace-sign-covered pillow, she opens Instagram. Later, Lila will give her a Starbucks gift card. Her dad will bring doughnuts to her class. Her grandparents will take her to the Melting Pot for dinner. But first, her friends will decide whether to post pictures of Katherine for her birthday. Whether they like her enough to put a picture of her on their page. Those pictures, if they come, will get likes and maybe tbhs. They should be posted in the morning, any minute now. She scrolls past a friend posing in a bikini on the beach. Then a picture posted by Kendall Jenner. A selfie with coffee. A basketball Vine. A selfie with a girl’s tongue out. She scrolls, she waits. For that little notification box to appear.

This is one of the most important reasons to keep a diary: it can make you more aware of your own progress, thus becoming a wellspring of joy in your workday.

We can’t, however, simply will ourselves into better habits. Since willpower is a limited resource, whenever we’ve overexerted our self-discipline in one domain, a concept known as “ego depletion” kicks in and renders us mindless automata in another

the key to changing a habit is to invest heavily in the early stages of habit-formation so that the behavior becomes automated and we later default into it rather than exhausting our willpower wrestling with it. Young also cautions that it’s a self-defeating strategy to try changing several habits at once. Rather, he advises, spend one month on each habit alone before moving on to the next

a diary boosts your creativity

the primary benefit of a diary as a purely pragmatic record of your workday productivity and progress — while most dedicated diarists would counter that the core benefits are spiritual and psychoemotional — it does offer some valuable insight into the psychology of how journaling elevates our experience of everyday life:

what you do every day is best seen as an iceberg, with a small fraction of conscious decision sitting atop a much larger foundation of habits and behaviors.

the authors point to a pattern that reveals the single most important motivator: palpable progress on meaningful work: On the days when these professionals saw themselves moving forward on something they cared about — even if the progress was a seemingly incremental “small win” — they were more likely to be happy and deeply engaged in their work. And, being happier and more deeply engaged, they were more likely to come up with new ideas and solve problems creatively.

Although the act of reflecting and writing, in itself, can be beneficial, you’ll multiply the power of your diary if you review it regularly — if you listen to what your life has been telling you. Periodically, maybe once a month, set aside time to get comfortable and read back through your entries. And, on New Year’s Day, make an annual ritual of reading through the previous year.

This, they suggest, can yield profound insights into the inner workings of your own mind — especially if you look for specific clues and patterns, trying to identify the richest sources of meaning in your work and the types of projects that truly make your heart sing. Once you understand what motivates you most powerfully, you’ll be able to prioritize this type of work in going forward. Just as important, however, is cultivating a gratitude practice and acknowledging your own accomplishments in the diary:

Fields argues that if we move along the Uncertainty Curve either too fast or too slowly, we risk either robbing the project of its creative potential and ending up in mediocrity. Instead, becoming mindful of the psychology of that process allows us to pace ourselves better and master that vital osmosis between freedom and constraint.

Schwalbe reminds us of the “impact bias” — our tendency to greatly overestimate the intensity and extent of our emotional reactions, which causes us to expect failures to be more painful than they actually are and thus to fear them more than we should.

When we think about taking a risk, we rarely consider how good we will be at reframing a disappointing outcome. In short, we underestimate our resilience.

The second reason is focalism. When we contemplate failure from afar, according to Gilbert and Wilson, we tend to overemphasize the focal event (i.e., failure) and overlook all the other episodic details of daily life that help us move on and feel better. The threat of failure is so vivid that it consumes our attention

don’t let yourself forget that the good life, the meaningful life, the truly fulfilling life, is the life of presence, not of productivity.

"self-transcendent emotions,"

I was beginning to see connections between experiences as varied as falling in love, watching a sunset from a hilltop, singing in a church choir, and reading about a virtuous person. In all cases there's a change to the self -- a kind of opening to our higher, nobler possibilities.

there was absolutely no scientific research on this emotion

religions are often quite skilled at producing such feelings

Some religions build awe-inspiring buildings; most tell morally elevating stories.

I wanted to shift attention away from that aspect of religion onto the more emotional and social aspects.

Whether or not you believe in God, religions accomplish something miraculous: They turn large numbers of people who are not kin into a group that is able to work together, trust each other, and help each other.

"The earlier they're introduced to a second language, the easier it will be for them to pick it up." Knowing a second (or third!) language could one day give your child an edge in an increasingly global workforce.

tend to have superior reading and writing skills in both languages, as well as better analytical and academic skills,

"Learning a language is a question of repeated high-quality exposure,"

"If a family reads a book to their child in Spanish as part of a bedtime routine, that's a lot of reading and a lot of learning over an extended period of time."

What you can expect: Results range from recognizing the language when it's spoken to being able to converse casually. The more time the child spends with the nanny or in bilingual daycare, the greater the proficiency. "It all depends on the amount and quality of the child's exposure,"

What you can expect: A bilingual tot, in time. Don't worry if he doesn't speak either language as adeptly as his monolingual peers at first. If your child is exposed to both languages the same amount, he will be able to speak both equally well by the time he goes to school.

rituals change the way we pay attention as much as — perhaps more than — they express belief.

Religion is fundamentally a practice that helps people to look at the world as it is and yet to experience it — to some extent, in some way — as it should be

rituals work, if by “work” we mean that they change people’s sense of their lives. It turns out that saying that you are grateful makes you feel grateful. Saying that you are thankful makes you feel thankful. To a world so familiar with the general unreliability of language, that may seem strange. But it is true.

In a study in which undergraduates were assigned to write weekly either about things they were grateful or thankful for; hassles; or “events or circumstances that affected you in the past week,” those who wrote about gratitude felt better about their lives as a whole, and were more optimistic about the coming week. There have now been many such studies.

ritual isn’t about expressing religious commitment at all, but about doing something in a way that marks the moment as different from the everyday and forces you to see it as important. Their point is that performing a ritual focuses your attention on some moment and deems it worthy of respect

Much of what people actually do in church — finding fellowship, celebrating birth and marriage, remembering those we have lost, affirming the values we cherish — can be accomplished with a sense of God as metaphor, as story, or even without any mention of God at all.

There are plenty of theories, of course, especially regarding why: increasingly complex social networks, a culture built around tool use and collaboration, the challenge of adapting to a mercurial and often harsh climate

Although these possibilities are fascinating, they are extremely difficult to test.

“What kinds of mutations occurred, and what did they do? We’re starting to get answers and a deeper appreciation for just how complicated this process was.”

contrary to long-standing assumptions, larger mammalian brains do not always have more neurons, and the ones they do have are not always distributed in the same way.

The human brain has 86 billion neurons in all: 69 billion in the cerebellum, a dense lump at the back of the brain that helps orchestrate basic bodily functions and movement; 16 billion in the cerebral cortex, the brain’s thick corona and the seat of our most sophisticated mental talents, such as self-awareness, language, problem solving and abstract thought; and 1 billion in the brain stem and its extensions into the core of the brain

In contrast, the elephant brain, which is three times the size of our own, has 251 billion neurons in its cerebellum, which helps manage a giant, versatile trunk, and only 5.6 billion in its cortex

primates evolved a way to pack far more neurons into the cerebral cortex than other mammals did

The great apes are tiny compared to elephants and whales, yet their cortices are far denser: Orangutans and gorillas have 9 billion cortical neurons, and chimps have 6 billion. Of all the great apes, we have the largest brains, so we come out on top with our 16 billion neurons in the cortex.

Although it makes up only 2 percent of body weight, the human brain consumes a whopping 20 percent of the body’s total energy at rest. In contrast, the chimpanzee brain needs only half that.

there was a strong evolutionary pressure to modify the human regulatory regions in a way that sapped energy from muscle and channeled it to the brain.

Accounting for body size and weight, the chimps and macaques were twice as strong as the humans. It’s not entirely clear why, but it is possible that our primate cousins get more power out of their muscles than we get out of ours because they feed their muscles more energy. “Compared to other primates, we lost muscle power in favor of sparing energy for our brains,” Bozek said. “It doesn’t mean that our muscles are inherently weaker. We might just have a different metabolism.

a pioneering experiment. Not only were they going to identify relevant genetic mutations from our brain’s evolutionary past, they were also going to weave those mutations into the genomes of lab mice and observe the consequences.

Silver and Wray introduced the chimpanzee copy of HARE5 into one group of mice and the human edition into a separate group. They then observed how the embryonic mice brains grew.

After nine days of development, mice embryos begin to form a cortex, the outer wrinkly layer of the brain associated with the most sophisticated mental talents. On day 10, the human version of HARE5 was much more active in the budding mice brains than the chimp copy, ultimately producing a brain that was 12 percent larger

“It wasn’t just a couple mutations and—bam!—you get a bigger brain. As we learn more about the changes between human and chimp brains, we realize there will be lots and lots of genes involved, each contributing a piece to that. The door is now open to get in there and really start understanding. The brain is modified in so many subtle and nonobvious ways.”

As recent research on whale and elephant brains makes clear, size is not everything, but it certainly counts for something. The reason we have so many more cortical neurons than our great-ape cousins is not that we have denser brains, but rather that we evolved ways to support brains that are large enough to accommodate all those extra cells.

There’s a danger, though, in becoming too enamored with our own big heads. Yes, a large brain packed with neurons is essential to what we consider high intelligence. But it’s not sufficient

No matter how large the human brain grew, or how much energy we lavished upon it, it would have been useless without the right body. Three particularly crucial adaptations worked in tandem with our burgeoning brain to dramatically increase our overall intelligence: bipedalism, which freed up our hands for tool making, fire building and hunting; manual dexterity surpassing that of any other animal; and a vocal tract that allowed us to speak and sing.

Human intelligence, then, cannot be traced to a single organ, no matter how large; it emerged from a serendipitous confluence of adaptations throughout the body. Despite our ongoing obsession with the size of our noggins, the fact is that our intelligence has always been so much bigger than our brain.

Shigir Idol

Dug out of a peat bog by gold miners in 1890, the relic, or what’s left of it, is carved from a great slab of freshly cut larch.

Scattered among the geometric patterns (zigzags, chevrons, herringbones) are eight human faces, each with slashes for eyes that peer not so benignly from the front and back planes.

“Whether it screams or shouts or sings, it projects authority, possibly malevolent authority. It’s not immediately a friend of yours, much less an ancient friend of yours.”

In archaeology, portable prehistoric sculpture is called “mobiliary art.”

The statue’s age was a matter of conjecture until 1997, when it was carbon-dated by Russian scientists to about 9,500 years old, an age that struck most scholars as fanciful.

The statue was more than twice as old as the Egyptian pyramids and Stonehenge, as well as, by many millenniums, the first known work of ritual art.

A new study that Dr. Terberger wrote with some of the same colleagues in Quaternary International, further skews our understanding of prehistory by pushing back the original date of the Shigir Idol by another 900 years, placing it in the context of the early art in Eurasia.

“During the period of rapid cooling from about 10,700 B.C. to 9,600 B.C. that we call the Younger Dryas, no beavers should have been around in the Transurals,” he said.)

Written with an eye toward disentangling Western science from colonialism, Dr. Terberger’s latest paper challenges the ethnocentric notion that pretty much everything, including symbolic expression and philosophical perceptions of the world, came to Europe by way of the sedentary farming communities in the Fertile Crescent 8,000 years ago.

“It’s similar to the ‘Neanderthals did not make art’ fable, which was entirely based on absence of evidence,

Likewise, the overwhelming scientific consensus used to hold that modern humans were superior in key ways, including their ability to innovate, communicate and adapt to different environments.

Nonsense, all of it.”

makes it clear that arguments about the wealth of mobiliary art in, say, the Upper Paleolithic of Germany or France by comparison to southern Europe, are largely nonsensical and an artifact of tundra (where there are no trees and you use ivory, which is archaeologically visible) versus open forest environments

The Shigir Idol, named for the bog near Kirovgrad in which it was found, is presumed to have rested on a rock base for perhaps two or three decades before toppling into a long-gone paleo-lake, where the peat’s antimicrobial properties protected it like a time capsule.

“It was not a scientific construction,”

“The rings tell us that trees were growing very slowly, as the temperature was still quite cold,”

Dr. Terberger respectfully disagrees.

“The landscape changed, and the art — figurative designs and naturalistic animals painted in caves and carved in rock — did, too, perhaps as a way to help people come to grips with the challenging environments they encountered.”

And what do the engravings mean? Svetlana Savchenko, the artifact’s curator and an author on the study, speculates that the eight faces may well contain encrypted information about ancestor spirits, the boundary between earth and sky, or a creation myth.

The temple’s stones were carved around 11,000 years ago, which makes them 1,500 years younger than the Shigir Idol.

One could wonder how many similar pieces have been lost over time due to poor preservation conditions.”

The similarity of the geometric motifs to others across Europe in that era, he added, “is evidence of long-distance contacts and a shared sign language over vast areas. The sheer size of the idol also seems to indicate it was meant as a marker in the landscape that was supposed to be seen by other hunter-gatherer groups — perhaps marking the border of a territory, a warning or welcoming sign.”

“What do you think is the hardest thing to find in the Stone Age archaeology of the Urals?”A pause: Sites?“No,” he said, sighing softly. “Funding.”

But these latest shifts challenge key infection control assumptions that go back a century, putting a lot of what went wrong last year in context

They may also signal one of the most important advancements in public health during this pandemic.

If the importance of aerosol transmission had been accepted early, we would have been told from the beginning that it was much safer outdoors, where these small particles disperse more easily, as long as you avoid close, prolonged contact with others.

We would have tried to make sure indoor spaces were well ventilated, with air filtered as necessary.

Instead of blanket rules on gatherings, we would have targeted conditions that can produce superspreading events: people in poorly ventilated indoor spaces, especially if engaged over time in activities that increase aerosol production, like shouting and singing

We would have started using masks more quickly, and we would have paid more attention to their fit, too. And we would have been less obsessed with cleaning surfaces.

The implications of this were illustrated when I visited New York City in late April — my first trip there in more than a year.

A giant digital billboard greeted me at Times Square, with the message “Protecting yourself and others from Covid-19. Guidance from the World Health Organization.”

That billboard neglected the clearest epidemiological pattern of this pandemic: The vast majority of transmission has been indoors, sometimes beyond a range of three or even six feet. The superspreading events that play a major role in driving the pandemic occur overwhelmingly, if not exclusively, indoors.

The billboard had not a word about ventilation, nothing about opening windows or moving activities outdoors, where transmission has been rare and usually only during prolonged and close contact. (Ireland recently reported 0.1 percent of Covid-19 cases were traced to outdoor transmission.)

Mary-Louise McLaws, an epidemiologist at the University of New South Wales in Sydney, Australia, and a member of the W.H.O. committees that craft infection prevention and control guidance, wanted all this examined but knew the stakes made it harder to overcome the resistance. She told The Times last year, “If we started revisiting airflow, we would have to be prepared to change a lot of what we do.” She said it was a very good idea, but she added, “It will cause an enormous shudder through the infection control society.”

In contrast, if the aerosols had been considered a major form of transmission, in addition to distancing and masks, advice would have centered on ventilation and airflow, as well as time spent indoors. Small particles can accumulate in enclosed spaces, since they can remain suspended in the air and travel along air currents. This means that indoors, three or even six feet, while helpful, is not completely protective, especially over time.

Meanwhile, many countries allowed their indoor workplaces to open but with inadequate aerosol protections. There was no attention to ventilation, installing air filters as necessary or even opening windows when possible, more to having people just distancing three or six feet, sometimes not requiring masks beyond that distance, or spending money on hard plastic barriers, which may be useless at best

To see this misunderstanding in action, look at what’s still happening throughout the world. In India, where hospitals have run out of supplemental oxygen and people are dying in the streets, money is being spent on fleets of drones to spray anti-coronavirus disinfectant in outdoor spaces. Parks, beaches and outdoor areas keep getting closed around the world. This year and last, organizers canceled outdoor events for the National Cherry Blossom Festival in Washington, D.C. Cambodian customs officials advised spraying disinfectant outside vehicles imported from India. The examples are many.

clear evidence doesn’t easily overturn tradition or overcome entrenched feelings and egos. John Snow, often credited as the first scientific epidemiologist, showed that a contaminated well was responsible for a 1854 London cholera epidemic by removing the suspected pump’s handle and documenting how the cases plummeted afterward. Many other scientists and officials wouldn’t believe him for 12 years, when the link to a water source showed up again and became harder to deny.

Along the way to modern public health shaped largely by the fight over germs, a theory of transmission promoted by the influential public health figure Charles Chapin took hold

Dr. Chapin asserted in the early 1900s that respiratory diseases were most likely spread at close range by people touching bodily fluids or ejecting respiratory droplets, and did not allow for the possibility that such close-range infection could occur by inhaling small floating particles others emitted

In a contemporary example of this attitude, the initial public health report on the Mount Vernon choir case said that it may have been caused by people “sitting close to one another, sharing snacks and stacking chairs at the end of the practice,” even though almost 90 percent of the people there developed symptoms of Covid-19

It was in this context in early 2020 that the W.H.O. and the C.D.C. asserted that SARS-CoV-2 was transmitted primarily via these heavier, short-range droplets, and provided guidance accordingly

Amid the growing evidence, in July, hundreds of scientists signed an open letter urging the public health agencies, especially the W.H.O., to address airborne transmission of the coronavirus.

Last October, the C.D.C. published updated guidance acknowledging airborne transmission, but as a secondary route under some circumstances, until it acknowledged airborne transmission as crucial on Friday. And the W.H.O. kept inching forward in its public statements, most recently a week ago.

Linsey Marr, a professor of engineering at Virginia Tech who made important contributions to our understanding of airborne virus transmission before the pandemic, pointed to two key scientific errors — rooted in a lot of history — that explain the resistance, and also opened a fascinating sociological window into how science can get it wrong and why.

Dr. Marr said that if you inhale a particle from the air, it’s an aerosol.

biomechanically, she said, nasal transmission faces obstacles, since nostrils point downward and the physics of particles that large makes it difficult for them to move up the nose. And in lab measurements, people emit far more of the easier-to-inhale aerosols than the droplets, she said, and even the smallest particles can be virus laden, sometimes more so than the larger ones, seemingly because of how and where they are produced in the respiratory tract.

Second, she said, proximity is conducive to transmission of aerosols as well because aerosols are more concentrated near the person emitting them. In a twist of history, modern scientists have been acting like those who equated stinky air with disease, by equating close contact, a measure of distance, only with the larger droplets, a mechanism of transmission, without examination.

Since aerosols also infect at close range, measures to prevent droplet transmission — masks and distancing — can help dampen transmission for airborne diseases as well. However, this oversight led medical people to circularly assume that if such measures worked at all, droplets must have played a big role in their transmission.

Another dynamic we’ve seen is something that is not unheard-of in the history of science: setting a higher standard of proof for theories that challenge conventional wisdom than for those that support it.

Another key problem is that, understandably, we find it harder to walk things back. It is easier to keep adding exceptions and justifications to a belief than to admit that a challenger has a better explanation.

The ancients believed that all celestial objects revolved around the earth in circular orbits. When it became clear that the observed behavior of the celestial objects did not fit this assumption, those astronomers produced ever-more-complex charts by adding epicycles — intersecting arcs and circles — to fit the heavens to their beliefs.

He was also concerned that belief in airborne transmission, which he associated with miasma theories, would make people feel helpless and drop their guard against contact transmission. This was a mistake that would haunt infection control for the next century and more.

So much of what we have done throughout the pandemic — the excessive hygiene theater and the failure to integrate ventilation and filters into our basic advice — has greatly hampered our response.

Some of it, like the way we underused or even shut down outdoor space, isn’t that different from the 19th-century Londoners who flushed the source of their foul air into the Thames and made the cholera epidemic worse.

Righting this ship cannot be a quiet process — updating a web page here, saying the right thing there. The proclamations that we now know are wrong were so persistent and so loud for so long.

the progress we’ve made might lead to an overhaul in our understanding of many other transmissible respiratory diseases that take a terrible toll around the world each year and could easily cause other pandemics.

So big proclamations require probably even bigger proclamations to correct, or the information void, unnecessary fears and misinformation will persist, damaging the W.H.O. now and in the future.

I’ve seen our paper used in India to try to reason through aerosol transmission and the necessary mitigations. I’ve heard of people in India closing their windows after hearing that the virus is airborne, likely because they were not being told how to respond

The W.H.O. needs to address these fears and concerns, treating it as a matter of profound change, so other public health agencies and governments, as well as ordinary people, can better adjust.

It needs to begin a campaign proportional to the importance of all this, announcing, “We’ve learned more, and here’s what’s changed, and here’s how we can make sure everyone understands how important this is.” That’s what credible leadership looks like. Otherwise, if a web page is updated in the forest without the requisite fanfare, how will it matter?

on these points — and for all of its virtues, buzz, spinoffs and a Pulitzer Prize — the 1619 Project has failed.

That doesn’t mean that the project seeks to erase the Declaration of Independence from history. But it does mean that it seeks to dethrone the Fourth of July by treating American history as a story of Black struggle against white supremacy — of which the Declaration is, for all of its high-flown rhetoric, supposed to be merely a part.

he deleted assertions went to the core of the project’s most controversial goal, “to reframe American history by considering what it would mean to regard 1619 as our nation’s birth year.”

She then challenged me to find any instance in which the project stated that “using 1776 as our country’s birth date is wrong,” that it “should not be taught to schoolchildren,” and that the only one “that should be taught” was 1619. “Good luck unearthing any of us arguing that,” she added.

I emailed her to ask if she could point to any instances before this controversy in which she had acknowledged that her claims about 1619 as “our true founding” had been merely metaphorical. Her answer was that the idea of treating the 1619 date metaphorically should have been so obvious that it went without saying.

“1619. It is not a year that most Americans know as a notable date in our country’s history. Those who do are at most a tiny fraction of those who can tell you that 1776 is the year of our nation’s birth. What if, however, we were to tell you that this fact, which is taught in our schools and unanimously celebrated every Fourth of July, is wrong, and that the country’s true birth date, the moment that its defining contradictions first came into the world, was in late August of 1619?”

Here is an excerpt from the introductory essay to the project by The New York Times Magazine’s editor, Jake Silverstein, as it appeared in print in August 2019 (italics added):

In his introduction, Silverstein argues that America’s “defining contradictions” were born in August 1619, when a ship carrying 20 to 30 enslaved Africans from what is present-day Angola arrived in Point Comfort, in the English colony of Virginia. And the title page of Hannah-Jones’s essay for the project insists that “our founding ideals of liberty and equality were false when they were written.”

What was surprising was that in 1776 a politically formidable “defining contradiction” — “that all men are created equal” — came into existence through the Declaration of Independence. As Abraham Lincoln wrote in 1859, that foundational document would forever serve as a “rebuke and stumbling block to the very harbingers of reappearing tyranny and oppression.”

As for the notion that the Declaration’s principles were “false” in 1776, ideals aren’t false merely because they are unrealized, much less because many of the men who championed them, and the nation they created, hypocritically failed to live up to them.

These two flaws led to a third, conceptual, error. “Out of slavery — and the anti-Black racism it required — grew nearly everything that has truly made America exceptional,” writes Silverstein.

Nearly everything? What about, say, the ideas contained by the First Amendment? Or the spirit of openness that brought millions of immigrants through places like Ellis Island? Or the enlightened worldview of the Marshall Plan and the Berlin airlift? Or the spirit of scientific genius and discovery exemplified by the polio vaccine and the moon landing?

On the opposite side of the moral ledger, to what extent does anti-Black racism figure in American disgraces such as the brutalization of Native Americans, the Chinese Exclusion Act or the internment of Japanese-Americans in World War II?

The world is complex. So are people and their motives. The job of journalism is to take account of that complexity, not simplify it out of existence through the adoption of some ideological orthodoxy.

This mistake goes far to explain the 1619 Project’s subsequent scholarly and journalistic entanglements. It should have been enough to make strong yet nuanced claims about the role of slavery and racism in American history. Instead, it issued categorical and totalizing assertions that are difficult to defend on close examination.

It should have been enough for the project to serve as curator for a range of erudite and interesting voices, with ample room for contrary takes. Instead, virtually every writer in the project seems to sing from the same song sheet, alienating other potential supporters of the project and polarizing national debate.

James McPherson, the Pulitzer Prize-winning author of “Battle Cry of Freedom” and a past president of the American Historical Association. He was withering: “Almost from the outset,” McPherson told the World Socialist Web Site, “I was disturbed by what seemed like a very unbalanced, one-sided account, which lacked context and perspective.”

In particular, McPherson objected to Hannah-Jones’s suggestion that the struggle against slavery and racism and for civil rights and democracy was, if not exclusively then mostly, a Black one. As she wrote in her essay: “The truth is that as much democracy as this nation has today, it has been borne on the backs of Black resistance.”

McPherson demurs: “From the Quakers in the 18th century, on through the abolitionists in the antebellum, to the Radical Republicans in the Civil War and Reconstruction, to the N.A.A.C.P., which was an interracial organization founded in 1909, down through the civil rights movements of the 1950s and 1960s, there have been a lot of whites who have fought against slavery and racial discrimination, and against racism,” he said. “And that’s what’s missing from this perspective.”

Wilentz’s catalog of the project’s mistakes is extensive. Hannah-Jones’s essay claimed that by 1776 Britain was “deeply conflicted” over its role in slavery. But despite the landmark Somerset v. Stewart court ruling in 1772, which held that slavery was not supported by English common law, it remained deeply embedded in the practices of the British Empire. The essay claimed that, among Londoners, “there were growing calls to abolish the slave trade” by 1776. But the movement to abolish the British slave trade only began about a decade later — inspired, in part, Wilentz notes, by American antislavery agitation that had started in the 1760s and 1770s.

ie M. Harris, an expert on pre-Civil War African-American life and slavery. “On Aug. 19 of last year,” Harris wrote, “I listened in stunned silence as Nikole Hannah-Jones … repeated an idea that I had vigorously argued against with her fact checker: that the patriots fought the American Revolution in large part to preserve slavery in North America.”

The larger problem is that The Times’s editors, however much background reading they might have done, are not in a position to adjudicate historical disputes. That should have been an additional reason for the 1619 Project to seek input from, and include contributions by, an intellectually diverse range of scholarly voices. Yet not only does the project choose a side, it also brooks no doubt.

“It is finally time to tell our story truthfully,” the magazine declares on its 1619 cover page. Finally? Truthfully? Is The Times suggesting that distinguished historians, like the ones who have seriously disputed aspects of the project, had previously been telling half-truths or falsehoods?

unlike other dates, 1776 uniquely marries letter and spirit, politics and principle: The declaration that something new is born, combined with the expression of an ideal that — because we continue to believe in it even as we struggle to live up to it — binds us to the date.

On the other, the 1619 Project has become, partly by its design and partly because of avoidable mistakes, a focal point of the kind of intense national debate that columnists are supposed to cover, and that is being widely written about outside The Times. To avoid writing about it on account of the first scruple is to be derelict in our responsibility toward the second.

We are already seeing the first wave of "who won and who lost" sorts of stories pitting various governors' responses against each other in horse-race fashion, as if these were early polls for the 2024 presidential election.

Then reality stepped in. A surge of summer cases forced the imposition of some restrictions on Floridians, like local mask mandates imposed by mayors in some cities in South Florida.

Now DeSantis is claiming again to be a master of pandemic control, as Florida's beach-tourism-restaurant industry is said to be doing well. Never mind that the state's seven-day infection rate of 143.9 per 100,000 population places it 12th highest of the 50 states.

For example, as of March 22, over the last seven days, Florida has had the most Covid-19 cases in the country, according to data from the US Centers for Disease Control and Prevention (CDC), the 12th highest per capita case-rate, the fourth highest number of deaths, and the 17th highest death rate.

Once celebrated for his pandemic management, he is now getting poor marks on managing. He has not strutted or had roundtables of fan-doctors to sing his praise. But the fact is California's recent numbers are much better than those of Florida, coming in at about 47th in the country with a case-rate 46.8 per 100,000, according to the CDC's data, and fewer deaths as well.

Florida is ignoring the death toll and instead pushing the upbeat metrics the governor would like America to pay attention to: jobs are up! and schools are open! DeSantis stood up to the Covid-19 threat like John Wayne would have done!

Rather than wallow in reality, she chose to celebrate an active economy and the joys of hunting season (note: the South Dakota new-infection rate is climbing the charts once again and sits at 105 per 100,000 South Dakotans ).

These rate-the-governors perspectives ignore a basic fact: it is no time for trophies.

Worse, this obeisance to economic and social factors as measure of success creates a series of disturbing false equivalencies as they compare deaths against the economy.

Measuring Covid-19 management on anything other than the number of human lives lost is not only disgraceful, it will also almost certainly lead us to make all the wrong decisions once again and usher in yet another Covid-19 resurgence in the US.

They also found that being raised in a nurturing environment could significantly counteract the detrimental effect of early adversities on IQ and help children achieve their full intellectual potential.

A nurturing environment also led to better growth and fewer psycho-social difficulties in adolescence, but it did not mitigate the effects of early adversities on growth and psycho-social difficulties."

one in five children are raised in poverty and 15 percent do not complete high school, with higher rates for children in Black and Hispanic families.

Parents want to provide nurturing environments and we need to help them." She said this includes interacting with young children in a positive way such as reading children's books from the library, singing songs together, and playing games with numbers and letters. Children who engage in age-appropriate chores with adult supervision like picking up toys and clearing the table gain skills and feel good about helping.

"This research highlights the importance of nurturing caregivers, both at home and at school to help children lead more productive lives as adults."

Yet the almost sing-songy declaration “I’m so OCD!” seems to be everywhere.

People with a common type of OCD can even have paralyzing anxiety over their own sexual orientation.

Since absolute certainty is rarely possible, almost no reassurance clears the yes, but hurdle, and that keeps the anxiety wheels spinning.

It’s common for people with OCD to believe that if they check the stove just once more, or Google just one more symptom of a disease they’re convinced they’ve got, then their mind will be clear.

“The brain is conditioned to alert us to anything that threatens our survival, but this system is malfunctioning in OCD,” says psychologist Steven Phillipson, clinical director of the Center for Cognitive-Behavioral Psychotherapy in New York City. “That can result in a tsunami of emotional distress that keeps your attention absolutely focused.”

For the person with OCD, he explains, the brain is signaling what feels like a life and death risk, and it’s hard to put a price on survival.

“Performing the ritual just convinces it that the danger is real and that only perpetuates the cycle.”

“It’s the moment when a panic marries a concept,”

If you can live with the uncertainty those dangers can cause—even if they make you uncomfortable—you likely don’t have OCD, or at least not a very serious case of it. If the anxiety is so great it consumes your thoughts and disrupts your day, you may have a problem.

Medications, including certain antidepressants, are often a big part of the solution, but psychotherapy—especially cognitive behavioral therapy (CBT)—can be just as effective.

progress up the ladder of perceived danger

“Big parts of our brains are devoted to making sense of touch and our skin has billions of cells that process information about it,”

“The right type of friendly touch—like hugging your partner or linking arms with a dear friend—calms your stress response down. [Positive] touch activates a big bundle of nerves in your body that improves your immune system, regulates digestion and helps you sleep well. It also activates parts of your brain that help you empathize.”

Psychologist Sheldon Cohen and other researchers at Carnegie Mellon University cited hugging specifically as a form of touch that can strengthen the immune system in a 2014 study investigating whether receiving hugs—and more broadly, social support that gives the perception that one is cared for—could make people less susceptible to one of the viruses that causes the common cold.

Broadly speaking, the participants who had reported having more social support were less likely to get sick—and those who got more hugs were far more likely to report feeling socially supported.

Everybody should be open to people being a little more socially distant and not touching as much. Some of it will return and some of it won’t.”

Although there’s no exact substitute for human touch, if you’re struggling with this aspect of self-isolating in particular, there are a few alternatives that can offer similar health benefits for people who are social distancing

“When we’re touched [in a positive way], a cascade of events happens in the brain and one of the important ones is the release of a neurochemical called oxytocin,”

Keltner adds that dancing, singing or doing yoga with others via an online platform can also be highly effective substitutes for physical contact

“Not only would it be good to prevent coronavirus disease; it probably would decrease instances of influenza dramatically in this country,”

Zak says U.S. customs like shaking hands and hugging may be changed forever and suggests that non-tactile greetings like a nod, bow or wave may come to replace them. However, he says it will still be important to find ways to reintroduce the humanity of positive touch into in-person interactions without putting anyone’s physical or mental health in jeopardy.

“In-person interactions have a big effect on the brain releasing oxytocin, but interacting via video is actually not that [different],” he explains. “It’s maybe 80% as effective. Video conferencing is a great way to see and be seen.”

But for those who are quarantining alone or with people with whom they don’t have physical contact, loneliness and social isolation are growing health concerns.

this process reduces stress and improves immunity. “That’s super valuable in a time of pandemic.”

If you’re using a video chat service for work or school, Zak recommends that you take five minutes at the beginning of the call to focus on interpersonal connection.

to illustrate how dance parties like Daybreaker can be beneficial for people’s physical and mental health. “When you create a dance experience driven by music, community and participation, that’s how you’re able to release all four happy brain chemicals,” Agrawal says.
