Anxiety Increases “Ability to Focus”

(p. C1) In a pair of studies published in the journal Emotion by Jeffrey Birk, myself and colleagues in 2011, we induced anxiety in young adults by asking them to vividly imagine being a passenger in a car accident and helping injured people in its aftermath. Compared with a second group who experienced a happy mood induction, the anxious group showed a greater ability to focus and control their attention during a computerized assessment.

Over the past decade, research has also shown something that many scientists didn’t expect: higher levels of dopamine, the “feel good” hormone, when we’re anxious. We have long known that dopamine spikes when an experience is pleasurable and also in anticipation of such rewards, activating brain areas that motivate and prepare us. The fact that anxiety also boosts dopamine levels points to its role in making positive possibilities into reality.

. . .

(p. C2) . . ., there are many ways to use anxiety to create a deeper sense of personal fulfillment. Beginning in 1938, the Harvard Study of Adult Development, one of the longest-running and most comprehensive longitudinal studies ever conducted, asked a fundamental question: What leads to a healthy and happy life? Following over 1,300 people from all walks of life over decades, the study has found that one of the best predictors—better than social class, IQ and genetic factors—is having a sense of purpose.

Wittgenstein Center’s Scenario Has Global Population Peak in 2050 at 8.7 Billion

(p. A2) Since the 1960s, when the global number of people first hit three billion, it has taken a bit over a decade to cross each new billion-person milestone, and so it might seem natural to assume that nine billion humans and then 10 billion are, inexorably, just around the corner. That is exactly what the latest population projections from the U.N. and the U.S. Census Bureau have calculated.

. . .

The U.N.’s projections are the best known. But an alternate set of projections has been gaining attention in recent years, spearheaded by the demographer Wolfgang Lutz, under the auspices of the Wittgenstein Centre for Demography and Global Human Capital at the University of Vienna, of which Mr. Lutz is founding director.

. . .

“There’s two big questions,” Mr. Lutz explains, that determine whether his forecasts or the U.N.’s end up closer to the mark. “First, how rapidly fertility will decline in Africa…. The other question is China, and countries with very low fertility, if they will recover and how fast they will recover.”

. . .

The Wittgenstein forecasts, by contrast, look not only at historical patterns, but attempt to ask why birthrates rise and fall. A big factor, not formally included in the U.N.’s models, is education levels. Put simply: As people, especially women, have greater opportunities to pursue education, they have smaller families.

. . .

The U.N. projects Africa’s population will grow from 1.3 billion today to 3.9 billion by century’s end.

Once education is accounted for, Wittgenstein’s baseline scenario projects Africa’s population will rise to 2.9 billion during that time period. In another scenario from Wittgenstein, which it calls the “rapid development” scenario, the population of Africa will only reach 1.7 billion by century’s end.

Wittgenstein’s phrase “rapid development” is revealing: This isn’t a forecast of doom and decline, but rather one in which health and education simply improve, a world with better human well-being, lower mortality, and medium levels of immigration.

. . .

Wittgenstein’s rapid-development scenario has the global population topping out at 8.7 billion in 2050.

River Erosion from Severe Storms Creates a “Huge Carbon Sink”

(p. D3) When it comes to carbon balance, some rivers are doing the world a favor. In areas of high erosion, a river carries bits of soil and vegetation to the sea. Those bits contain much organic carbon, converted from atmospheric carbon dioxide by plants, so if they end up at the bottom of the ocean, the river has served as the transport mechanism for a huge carbon sink.

. . .

In a report in Nature Geoscience, the researchers calculate that the typhoon effect is so great that over several decades, almost all of the transport of organic carbon by the river occurs during storm-caused floods.

artdiamondblog.com Is Partly a Shared Digital Commonplace Book

In describing the purpose of this blog, I have sometimes called it a digital shared commonplace book, focusing especially on the topics that I focus most of my research on: entrepreneurship and innovation.

(p. B5) Creating a commonplace book is somewhat like marking your favorite lines in a novel with the Amazon Kindle highlights feature — except your personal one-stop knowledge repository can also include song lyrics, movie dialogue, poems, recipes, podcast transcripts, and any inspiring bits you find in your reading and listening. The commonplace book is not a new concept: Copying down your favorite lines from other people’s works into your own annotated notebook was a standard exercise in Renaissance Europe, and the idea can be traced to the Roman era.

. . .

If you’ve never made a commonplace book before, first learn how others have used them. Academic libraries, along with museums, are home to many commonplace books, and you can see them without leaving the couch. John Milton’s commonplace book is on the British Library site, and the personal notebooks of other writers and thinkers pop up easily with a web search.

The Yale University Library has scanned pages of historical commonplace books in its holdings, and the Harvard Library has a few in its own online collection, as well as images of a version of John Locke’s 17th-century guide to making commonplace books, which was originally published in French. And the Internet Archive has hundreds of digitized commonplace books for browsing or borrowing, including one from Sir Alec Guinness.

Jellyfish Genome Suggests Multiple Pathways Can Synergize to Extend Healthy Lifespans

(p. A3) A team of scientists in Spain has succeeded in mapping the genome of a jellyfish known for its ability to cheat death by rebirthing itself.

. . .

In a study published Monday [Aug. 29, 2022] in the Proceedings of the National Academy of Sciences, the authors said they hoped their genome mapping might lead to discoveries relevant to human aging and efforts to improve the human healthspan.

. . .

Three types can rejuvenate after adulthood and of those three, only one, the Turritopsis dohrnii, keeps its capacity at 100%, according to the study.

. . .

The scientists compared their genome mapping of T. dohrnii to that of a closely related species that isn’t known to have post-reproductive rejuvenation.

. . .

Dr. Jan Karlseder, a molecular biologist and director of the Glenn Center for Biology of Aging Research at the Salk Institute, said the study contained an important message about extending the healthspan, or healthy years, of an organism.

“The most interesting thing is that it’s not a single molecular pathway . . . It is a combination of many of them,” he said. “If we want to look for an extension of healthspan, we cannot just focus on one pathway. That will not be sufficient. We need to look at many of them and how they synergize.”

Freedom of Speech Matters “Above All Liberties”

(p. C14) Today, Milton is best known for “Paradise Lost.” Long before writing that epic poem about the fall of man, however, he was a polemicist who participated in the political controversies of his day.

. . .

A bill in Parliament demanded that printers receive government approval for their publications, in part to guard against the supposed heresies of Milton and his fellow authors. For Milton, this licensing scheme was an illiberal outrage—and he said so in “Areopagitica,” which is now widely regarded as the world’s first important essay in defense of free speech.

The 1644 treatise takes its peculiar name from the Areopagus, a rocky mount just below the Acropolis in Athens. The ancient Greeks gathered there for debates and trials. It’s also the site of Paul’s sermon in Acts 17. Milton presented his essay in the form of a speech, though he never delivered it. That’s probably just as well: At nearly 18,000 words, it would have taken about three hours.

“Give me the liberty to know, to utter, and to argue freely according to conscience, above all liberties,” wrote Milton, in a line that has echoed across centuries.

. . .

A minor curiosity of “Areopagitica” is Milton’s brief mention of visiting “the famous Galileo grown old, a prisner to the Inquisition, for thinking in Astronomy otherwise then the Franciscan and Dominican licencers thought.” This is the only record of a meeting between the era’s greatest scribe and its greatest scientist, and it would have happened when Milton traveled to Italy in 1638.

Though Visible, Not Everyone Saw the Unexpected Buckyball

(p. A24) Robert F. Curl Jr., who shared the 1996 Nobel Prize in Chemistry as one of the discoverers of remarkably simple but completely unexpected carbon molecules known as buckyballs, died on July 3 at a retirement home in Houston. He was 88.

His death was announced by Rice University, where Dr. Curl was a professor emeritus of chemistry.

Buckyballs, with their round, hollow structure, upended chemists’ notions of what was possible for the shapes of molecules. A flood of scientists started studying them, spurring the nascent field of nanotechnology and dreams of building molecule-size machines.

. . .

The finding was serendipitous, because they had been looking for something else.

“You could argue it wasn’t any of our areas of interest,” James R. Heath, a graduate student of Dr. Smalley’s who performed many of the buckyball experiments, said in an interview.

. . .

For the experiment, Dr. Kroto was interested in molecules containing long chains of carbon that had been observed in interstellar space. He hypothesized that the long-chain molecules were created in the atmospheres of carbon-rich red giant stars.

. . .

At a science conference in 1984, Dr. Kroto ran into Dr. Curl, an old friend. Dr. Curl told him about an apparatus of Dr. Smalley’s that used a laser to create an intensely hot vapor that coalesced into clusters. Dr. Kroto realized that this apparatus could create conditions similar to those in the atmosphere of a red giant.

. . .

. . . Dr. Smalley finally agreed to try it, and the three professors, along with Dr. Heath and two graduate students, started their work.

They indeed discovered the long carbon chains that Dr. Kroto had wanted to find.

They also found something else — the buckyballs.

Dr. Heath said Dr. Curl provided a healthy dose of skepticism during the 11-day whirlwind of discovery.

“All of us were like excitable kids,” Dr. Heath said. “And Bob was like the adult in the room. And he would come up with reasons that we had to go back and test and make sure that this was right or that was correct. We all viewed Bob not like he was a devil’s advocate — more like he was an insurance policy. If Bob agreed with you, you were probably right.”

It turned out that the Exxon experiments had also created small numbers of buckyballs, but those researchers had overlooked them in their data. At Rice, the scientists realized what they had found.

Leftist Anti-Covid-Vaccine Roman Catholic Nun Defends Free Speech

(p. A12) MONTSERRAT, Spain — Sister Teresa Forcades came to public notice years ago for her unflinching liberal views: an outspoken Roman Catholic nun whose pronouncements ran counter to the church’s positions on same-sex marriage and abortion.

She became a fixture on Spanish television, appearing in her nun’s habit to advocate independence for her native region of Catalonia, and to debate other hot-button topics, including vaccines. She had trained as a doctor, partly in the United States, and argued that vaccinations might one day pose a danger to a free society.

. . .

“It’s always important that criticism is possible, to have dissenting voices,” she said of her views, which center as much on her doubts about the vaccines as her right to question them in public. “The answer cannot be that in the time of a crisis, society cannot allow the criticism — it’s precisely then that we need it.”

. . .

In the world of vaccine skeptics, Sister Teresa, who was born in 1966 to a nurse and a commercial agent, is hard to categorize. She acknowledges that some vaccines are beneficial, but opposes making them mandatory. Her misgivings about coronavirus vaccines largely stem from her view that pharmaceutical companies are not to be trusted, and the clinical trials were rushed.

. . .

Sister Teresa, though staunchly leftist, doesn’t distance herself from right-wing followers, calling her distrust of some vaccines a “transversal question able to reach a wide spectrum of people.”

Those Who Survived Dictatorship Know We Need “More Freedom, More Speech, Not Less”

(p. A19) The left’s reaction to Mr. Trump’s rhetoric was instructive. Anyone who mentioned the lab-leak theory was assailed as pro-Trump. Social-media companies removed posts mentioning it. By January 2021, it was obvious that shutting down debate was the true antiscience position. Invaluable months were lost, time the Chinese Communist Party used to destroy data and spread disinformation about the virus’s origins. We may never know the truth, but we do know there was a coverup.

Increasing numbers of Americans believe their freedom is under attack, and I agree. . . .

Schools are being pressured to remove books and cancel professors for spreading the “wrong” ideas. These sentiments are all too familiar to me, and to anyone who has survived life in a dictatorship. The only answer is more freedom, more speech, not less.

Wary, Subdued Infants Tend to Grow into “Anxious, Inhibited Adults”

(p. A21) Prof. Jerome Kagan, a Harvard psychologist whose research into temperament found that shy infants often grow up to be anxious and fearful adults because of their biological nature as well as the way they were nurtured, died on May 10 in Chapel Hill, N.C.

. . .

Professor Kagan argued in more than two dozen books, including the widely praised “The Nature of the Child” (1984), that some children were genetically wired to worry and that they proved to be more resilient than expected as they passed from one stage of maturity to another. He also contended that the specifics of parenting were often not as crucial to a child’s future as parents think, although the child’s natural predisposition to be shy or exuberant could be altered by experience.

. . .

Professor Kagan and his collaborators, including Howard A. Moss and Nancy C. Snidman, pioneered the reintroduction of physiology as a determinant of psychological characteristics that could be measured in the brain.

They derived their conclusions from lengthy studies that started with the videotaped reactions of toddlers and infants as young as 4 months to various stimuli — unfamiliar objects, people and situations — and correlated those reactions to their temperament as teenagers and beyond, as measured in interviews.

The wary ones who were subdued, shy and hovered around their mothers or who fussed, thrashed around and cried — about 15 percent of the total — tended to become anxious, inhibited adults. Another 15 percent who were ebullient as infants and embraced every new toy and interviewer tended to develop into fearless children and adolescents.

Professor Kagan acknowledged that as an ideological liberal he had originally believed that all individuals were capable of achieving similar goals if afforded the same opportunities. “I was so resistant to awarding biology much influence,” he wrote.

“Paradox”: “Masks Work and Mask Mandates Do Not Work”

(p. A19) The Evidence

From the beginning of the pandemic, there has been a paradox involving masks. As Dr. Shira Doron, an epidemiologist at Tufts Medical Center, puts it, “It is simultaneously true that masks work and mask mandates do not work.”

To start with the first half of the paradox: Masks reduce the spread of the Covid virus by preventing virus particles from traveling from one person’s nose or mouth into the air and infecting another person. Laboratory studies have repeatedly demonstrated the effect.

Given this, you would think that communities where mask-wearing has been more common would have had many fewer Covid infections. But that hasn’t been the case.

In U.S. cities where mask use has been more common, Covid has spread at a similar rate as in mask-resistant cities. Mask mandates in schools also seem to have done little to reduce the spread. Hong Kong, despite almost universal mask-wearing, recently endured one of the world’s worst Covid outbreaks.

Advocates of mandates sometimes argue that they do have a big effect even if it is not evident in populationwide data, because of how many other factors are at play. But this argument seems unpersuasive.

After all, the effect of vaccines on severe illness is blazingly obvious in the geographic data: Places with higher vaccination rates have suffered many fewer Covid deaths. The patterns are clear even though the world is a messy place, with many factors other than vaccines influencing Covid death rates.

Yet when you look at the data on mask-wearing — both before vaccines were available and after, as well as both in the U.S. and abroad — you struggle to see any patterns.

Almost 30 Percent

The idea that masks work better than mask mandates seems to defy logic. It inverts a notion connected to Aristotle’s writings: that the whole should be greater than the sum of the parts, not less.

The main explanation seems to be that the exceptions often end up mattering more than the rule. The Covid virus is so contagious that it can spread during brief times when people take off their masks, even when a mandate is in place.
