Observations of Non-Credentialed Citizens Add to “Scientific” Knowledge

(p. D5) In 1811, a 12-year-old girl named Mary Anning discovered a fossil on the beach near her home in southwestern England — the first scientifically identified specimen of an ichthyosaur, a dolphin-like, ocean-dwelling reptile from the time of the dinosaurs. Two centuries later, less than 50 miles away, an 11-year-old girl named Ruby Reynolds found a fossil from another ichthyosaur. It appears to be the largest marine reptile known to science.

Ms. Reynolds, now 15, and her father, Justin Reynolds, have been fossil hunting for 12 years near their home in Braunton, England. On a family outing in May 2020 to the village of Blue Anchor along the estuary of the River Severn, they came across a piece of fossilized bone set on a rock.

“We were both excited as we had never found a piece of fossilized bone as big as this before,” Mr. Reynolds said. His daughter kept searching the beach, he added, “and it wasn’t long before she found another much larger piece of bone.”

They took home the fragments of bone, the largest of which was about eight inches long, and began their research. A 2018 paper provided a hint at what they’d found: In nearby Lilstock, fossil hunters had discovered similar bone fragments, hypothesized to be part of the jaw bone of a massive ichthyosaur that lived roughly 202 million years ago. However, the scientists who’d worked on the Lilstock fossil had deemed that specimen too incomplete to designate a new species.

Mr. Reynolds contacted those researchers: Dean Lomax, at the University of Bristol, and Paul de la Salle, an amateur fossil collector. They joined the Reynolds family on collecting trips in Blue Anchor, digging in the mud with shovels. Ultimately, they found roughly half of a bone that they estimate would have been more than seven feet long when complete.

. . .

Dr. Lomax said that this discovery also highlighted the importance of amateur fossil collectors. “If you have a keen eye, if you have a passion for something like that, you can make discoveries like this,” he said.

Ruby Reynolds said: “I didn’t realize when I first found the piece of ichthyosaur bone how important it was and what it would lead to. I think the role that young people can play in science is to enjoy the journey of exploring as you never know where a discovery may take you.”

Mao’s Red Guard “Just Wanted to Beat Us to Death”

(p. C7) The Cultural Revolution is the monster that lurks behind the Communist Party’s claims of harmonious, orderly leadership in China. Under Mao’s direction, fanatical youth turned on their teachers, their parents, all figures of authority. This was an era of torture and violence, committed in many cases by mere children. Nobody was safe—perpetrators became victims, and victims took revenge. As many as two million died, and tens of millions had their lives destroyed.

. . .

In “Red Memory” the author explores how people in 21st-century China continue to process a collective trauma that the government would prefer to erase, even as the Party itself cannot put Mao behind it. The book unfolds as a series of portraits of people and settings tied to the events from half a century ago.

. . .

A music composer who was savagely tortured tells Ms. Branigan that he used to think there was some catharsis at work behind the violence, a correction of some kind to help bind people together. But there was not. “I wasn’t helping them at all,” he said of his tormentors. “They just wanted to beat us to death.”

. . .

The reporting in this book was gathered between 2008 and 2015, when Ms. Branigan was a Guardian correspondent in China. Poignantly, she observes that she could not have conducted such interviews today. In the past several years, even greater pressure has come down on those who wish to remember a past the Party wants to forget. People who spoke freely with her 10 years ago might not risk doing so today. The internet sites of commemoration have been shut down.

Economical Parrots Decline an Immediate Smaller Treat to Be Able to Trade a Token for a Bigger Treat

(p. D3) Chalk up another achievement for parrots, . . . .

Anastasia Krasheninnikova and colleagues at the Max Planck Institute for Ornithology in Germany tested four species of parrots in an experiment that required trading tokens for food and recently reported their findings in the journal Scientific Reports.

. . .

A metal hoop could be traded for a piece of dry corn, the lowest value food, a metal bracket for a medium value sunflower seed and a plastic ring for the highest value food, a piece of shelled walnut.

The birds were then offered various choices, like a piece of corn or the ring. They all reliably chose to forgo the corn and take the ring. Then they were able to trade the ring for a piece of walnut.

They also did well choosing a bracket instead of the corn, and in other situations where the token was of higher value than the food.

To Save One Species of Brown Owl, the Feds Want to Shoot Hundreds of Thousands of a More Adaptable Similar-Looking Species of Brown Owl

Isn’t it interesting that many in the Pacific Northwest and in the federal government want to take guns away from self-defending citizens at the same time that they want to use large-bore shotguns to shoot hundreds of thousands of barred owls whose only sin is that, unlike the spotted owls who they resemble, they are not picky eaters?

(p. D1) In the ancient forests of the Pacific Northwest, the northern spotted owl, a rare and fragile subspecies of spotted owl, is being muscled out of its limited habitat by the barred owl, its larger and more ornery northeastern cousin. The opportunistic barred owl has been moving in on spotted owl turf for more than half a century, competing with the locals for food and space, outnumbering, out-reproducing and inevitably chasing them out of their nesting spots. Barred owls have also emerged as a threat to the California spotted owl, a closely related subspecies in the Sierra Nevada and the mountains of coastal and Southern California.

. . .

(p. D5) In a last-ditch effort to rescue the northern spotted owl from oblivion and protect the California spotted owl population, the U.S. Fish and Wildlife Service has proposed culling a staggering number of barred owls across a swath of 11 to 14 million acres in Washington, Oregon and Northern California, where barred owls — which the agency regards as invasive — are encroaching. The lethal management plan calls for eradicating up to half a million barred owls over the next 30 years, or 30 percent of the population over that time frame. The owls would be dispatched using the cheapest and most efficient methods, from large-bore shotguns with night scopes to capture and euthanasia.

. . .

The agency’s plan, outlined last fall in a draft report assessing its environmental impact that is due for final review this summer, has pitted conservationists, who say it will benefit both species, against animal supporters, who consider the proposed scale, scope and timeline unsustainable.

Last month, a coalition of 75 wildlife protection and animal welfare organizations sent a letter to Secretary of the Interior Deb Haaland urging her to scrap what they called a “colossally reckless action” that would necessitate a perpetual killing program to keep the number of barred owls in check. Wayne Pacelle, the president of Animal Wellness Action and an author of the statement, said it was dangerous for the government to start managing competition and social interaction among North American species, including ones that have expanded their range as a partial effect of “human perturbations” of the environment. “I cannot see how this succeeds politically, because of its price tag and its sweeping ambitions,” he said in an email.

Mr. Pacelle questions whether barred owls, which are indigenous to North America, truly meet the criteria for an invasive species. “This ‘invasive’ language rings familiar to me in our current political debates,” he said. “Demonize the migrants, and the harsh policy options become much easier from a moral perspective.”

The signatories argued that the current predicament warranted nonlethal control, and that the agency’s approach would lead to the wrong owls being shot and to the death of thousands of eagles, hawks and other creatures from lead poisoning. “Implementing a decades-long plan to unleash untold numbers of ‘hunters’ in sensitive forest ecosystems is a case of single-species myopia regarding wildlife control,” the letter said.

. . .

At first sight, it’s easy to mistake a spotted for a barred: Both have tuftless rounded heads, teddy bear eyes and bodies mottled brown and white. They can interbreed to produce chicks called sparred owls. But they differ in their habitat requirements. Up to four pairs of barred owls can occupy the three-to-12 square miles that one spotted couple needs, and barred owls aggressively defend their terrain. “The closer spotted owls live to barred owls, the less likely the spotted owls are to have offspring,” Dr. Wiens said. Barred owls also produce four times as many young.

Spotted owls are extremely picky eaters: In California, they eat only flying squirrels and wood rats. “Barred owls devour anything and everything,” Ms. Bloem said, . . .

Repeated Interbreeding of Brown Bears and Polar Bears Illustrates Fuzziness of Defining a Species

(p. D1) Naturalists have been trying for centuries to catalog all of the species on Earth, and the effort remains one of the great unfinished jobs in science. So far, researchers have named about 2.3 million species, but there are millions — perhaps even billions — left to be discovered.

As if this quest isn’t hard enough, biologists cannot agree on what a species is. A 2021 survey found that practicing biologists used 16 different approaches to categorizing species. Any two of the scientists picked at random were overwhelmingly likely to use different ones.

“Everyone uses the term, but no one knows what it is,” said Michal Grabowski, a biologist at the University of Lodz in Poland.

The debate over species is more than an academic pastime. In the current extinction crisis, scientists urgently need to take stock of the world’s biological diversity.

. . .

(p. D4) As scientists gather more genetic data, fresh questions are emerging about what seem, on the surface, to be obviously separate species.

You don’t have to be a mammalogist to understand that polar bears and brown bears are different. Just one look at their white and brown coats will do.

The difference in their colors is the result of their ecological adaptations. White polar bears blend into their Arctic habitats, where they hunt for seals and other prey. Brown bears adapted for life on land further south. The differences are so distinct that paleontologists can distinguish fossils of the two species going back hundreds of thousands of years.

And yet the DNA inside those ancient bones is revealing an astonishing history of interbreeding between polar bears and brown bears. After the two lineages split about half a million years ago, they exchanged DNA for thousands of years. They then became more distinct, but about 120,000 years ago they underwent another extraordinary exchange of genes.

Between 25,000 and 10,000 years ago, the bears interbred in several parts of their range. The exchanges have left a significant imprint on bears today: About 10 percent of the DNA in brown bears comes from polar bears.

Beth Shapiro, a paleogeneticist at the University of California, Santa Cruz, said that the interbreeding most likely occurred when swings in the climate forced polar bears down from the Arctic and into brown bear territory.

Nobelist Phelps Opposes a Universal Basic Income, Since Recipients Might Miss the Fulfilment That Comes from Meaningful Work

UBI below stands for Universal Basic Income.

(p. C9) And yet Mr. Phelps, the winner of the 2006 Nobel Prize in economics and emeritus professor of political economy at Columbia University, is among the most lucid, passionate and original defenders of capitalism. (He is also the founding director of Columbia’s Center on Capitalism and Society.) He disparages European-style corporatist economies as being unsuited to dynamism or innovation. Progressives who’d claim him as their own would do well to remember that he takes a hostile view of the idea of a universal basic income.

In “My Journeys in Economic Theory,” Mr. Phelps declares that it is “disappointing that UBI”—embraced by such modish politicians as Andrew Yang and Alexandria Ocasio-Cortez—“has not received widespread opposition.” The idea, if implemented, “would entice people and their children away from meaningful work and thus from a sense of involvement in the economy—society’s central project.”

It is this last, humane observation that distinguishes Mr. Phelps from the economists’ tribe, reflecting his belief that the nobility of capitalism lies in the chance it offers for prosperity and self-discovery on a national scale. He calls this phenomenon “mass flourishing,” words that make up the title of his late-in-life magnum opus, published in 2013 when he was 80.

. . .

It is apparent in his memoirs that Mr. Phelps wishes to be remembered most for his theories of the past two decades, which focus on the workplace and creativity. He believes that economists are mistaken in their supposition that the reward for work is pay alone. As he writes in “Dynamism” (2020), in America “it is very clear that work is central to a meaningful life.” People at all rungs of the economy “possess imagination and creativity,” and the modern economy is “a vast imaginarium” in which growth comes from “creativity within the workforce.”

Mr. Phelps underscores a connection between economic growth and job satisfaction. He urges economists “not to stop at the standard theory” but to explore an “uncharted realm” of human desires and fulfillments. There’s more to life than capital, mere employment and national income. And certainly more to economics.

Elephants Have Backup or “Resurrected” Copies of Cancer-Killing Genes

(p. D3) Elephants ought to get a lot of cancer. They’re huge animals, weighing as much as eight tons. It takes a lot of cells to make up that much elephant.

All of those cells arose from a single fertilized egg, and each time a cell divides, there’s a chance that it will gain a mutation — one that may lead to cancer.

Strangely, however, elephants aren’t more prone to cancer than smaller animals. Some research even suggests they get less cancer than humans do.

On Tuesday [Aug. 14, 2018 [sic]], a team of researchers reported what may be a partial solution to that mystery: Elephants protect themselves with a unique gene that aggressively kills off cells whose DNA has been damaged.

Somewhere in the course of evolution, the gene had become dormant. But somehow it was resurrected, a bit of zombie DNA that has proved particularly useful.

Vincent J. Lynch, an evolutionary biologist at the University of Chicago and a co-author of the paper, published in Cell Reports, said that understanding how elephants fight cancer may provide inspiration for developing new drugs.

. . .

In 2015, Dr. Lynch and his colleagues discovered that elephants have evolved unusual p53 genes. While we only have one copy of the gene, elephants have 20 copies. Researchers at the University of Utah independently made the same discovery.

. . .

Dr. Lynch and his colleagues continued their search for cancer-fighting genes, and they soon encountered another one, called LIF6, that only elephants seem to possess.

In response to DNA damage, p53 proteins in elephants switch on LIF6. The cell makes LIF6 proteins, which then wreak havoc.

Dr. Lynch’s experiments indicate that LIF6 proteins make their way to the cell’s tiny fuel-generating factories, called mitochondria.

The proteins pry open holes in the mitochondria, allowing molecules to pour out. The molecules from mitochondria are toxic, causing the cell to die.

. . .

After the ancestors of elephants evolved ten LIF genes, however, something remarkable happened: One of these dead genes came back to life. That gene is LIF6.

Somewhere in the course of elephant evolution, a cellular mutation inserted a genetic switch next to LIF6, enabling the gene to be activated by p53. The resurrected gene now made a protein that could do something new: attack mitochondria and kill damaged cells.

“Never Say Die” in Search of Species That We’ve Declared Extinct

(p. D1) Just a few years ago, it seemed like the scarce yellow sally stonefly had gone locally extinct.

In 1995, ecologists collected a single specimen of the aquatic insect in the River Dee near the Wales-England boundary, the species’ only known refuge. For the next two decades, every survey there failed to find another of the stonefly, which is only about a half an inch long.

“There had been so much work done to refind this beast,” said Craig Macadam, conservation director at the Invertebrate Conservation Trust, more commonly known as Buglife, a charity in Britain. “We were all beginning to give up hope.”

. . .

(p. D5) “When you actually see the animal alive in front of you and then the next year it’s gone, you feel like you’ve watched it disappear from Earth,” Mr. Davy-Bowker said. “Nobody could find it, so that was it. It just disappeared.”

But Mr. Davy-Bowker wouldn’t quit. In March 2017, during the season when the River Dee is at its coldest and deepest and stonefly nymphs are large, he put on chest waders and went in.

. . .

About 20 minutes into that day’s expedition, Mr. Davy-Bowker captured a living scarce yellow sally stonefly, upending 22 years of presumed local extinction.

“I couldn’t believe it. I was absolutely staggered, really,” he said. “I can’t tell you what a thrill it was to find it again. Never say die.”

. . .

Mr. Macadam, of the Buglife conservation charity, said the species’ rediscovery has rekindled hope for other critically endangered invertebrates that have gone missing.

“For me, it opened up the possibility that there is another species that we’ve declared extinct, that is still holding on somewhere,” he said.

Patients Know Their Condition and Should Be Listened to by Physicians

The article quoted below gives evidence that on average the patients of female physicians have slightly better health outcomes than the patients of male physicians, and speculates that the reason is that on average, female physicians are somewhat better at listening than are male physicians. The article does not highlight an important implication of this speculation: that what the patient is saying is worth listening to, i.e., it has merit, often providing true and useful knowledge about their own condition. Patients actually know something. If so, this goes against the popular views that physicians should be paternalistic, and that the only actionable source of health knowledge is a randomized double-blind clinical trial.

(p. D4) Whether your doctor is male or female could be a matter of life or death, a new study suggests. The study, of more than 580,000 heart patients admitted over two decades to emergency rooms in Florida, found that mortality rates for both women and men were lower when the treating physician was female. And women who were treated by male doctors were the least likely to survive.

Earlier research supports the findings. In 2016, a Harvard study of more than 1.5 million hospitalized Medicare patients found that when patients were treated by female physicians, they were less likely to die or be readmitted to the hospital over a 30-day period than those cared for by male doctors. The difference in mortality was slight — about half a percentage point — but when applied to the entire Medicare population, it translates to 32,000 fewer deaths.

Other studies have also found meaningful differences in how women and men practice medicine. Researchers at Johns Hopkins Bloomberg School of Public Health analyzed a number of studies that focused on how doctors communicate. They found that female primary care doctors simply spent more time listening to patients than did their male colleagues. But listening comes with a cost. Doctors who were women spent, on average, two extra minutes, or about 10 percent more time per visit, creating scheduling delays and putting them an hour or more behind their male colleagues by the end of the day.

Dr. Nieca Goldberg, a cardiologist whose book “Women Are Not Small Men” helped start a national conversation about heart disease in women, said the research should not be used to disparage male doctors, but should instead empower patients to find doctors who listen.

. . .

Edna Haber, a retired mortgage company owner who lives in Westchester County in New York, said she has had wonderful male and female doctors, but her worst experiences have all involved male doctors.  . . .

Recently she decided to see Dr. Goldberg to discuss heart palpitations and feeling lightheaded. But a series of medical tests during the office visit found that her heart was normal. “I do believe that had I been with a male doctor, I think he just would have put his arm around me and said, ‘Listen, go home, relax, meditate, maybe take a tranquilizer,’ and that would have been the end of it.”

But Dr. Goldberg knew the patient had been concerned enough to see a doctor, so she suggested that she wear a heart monitor for a few days. Several days later, the technicians monitoring the feed noticed a pattern that ultimately showed Ms. Haber needed a pacemaker.

“She paid attention and treated me as if I was credible,” said Ms. Haber. “I wish all the women I know could understand how important it is to have a doctor who pays attention to them, whatever part of the body they are looking at. I think a lot of women are getting short shrift.”

University of Chicago Press Undermines Its Own New Edition of Milton Friedman’s Capitalism and Freedom

(p. C9) I had never read “Capitalism and Freedom” and was renewed in my admiration for midcentury American reading audiences. The book, full of tightly reasoned arguments about the principles of economic freedom in various spheres of life, sold 400,000 copies in its first 18 years. The University of Chicago Press, which first published the book six decades ago, evidently would rather it stop selling. The new edition’s foreword is written by Binyamin Appelbaum, a member of the New York Times editorial board, who treats Friedman’s classic text as mildly interesting artifact. “Friedman’s claim that ‘widespread use of the market reduces the strain on the social fabric,’ ” Mr. Appelbaum assures us, “misapprehended the nature of society, which is more like a muscle than a fabric.” I await Chicago’s edition of J.K. Galbraith’s “The Affluent Society,” with a foreword by Larry Kudlow.

Buy Health Supplements Certified by “a Trusted Third Party” Like U.S. Pharmacopeia (USP)

According to a Consumer Reports article, “USP is a nonprofit organization that sets what CR experts say are the most widely accepted standards for supplements.” Note that with the services of private organizations such as USP, attentive consumers can be safe without the heavy hand of government regulators.

(p. D6) . . . most supplements have not been rigorously tested for safety or effectiveness, said Dr. JoAnn Manson, a professor of medicine at Harvard Medical School.

. . .

But, she said, there are some instances where taking a supplement may improve your health. Here are some of the main ones.

If a blood test reveals that your body is low in a particular vitamin or mineral, such as vitamin D or iron, supplements can be “essential” in correcting that deficiency, said Dr. Pieter Cohen, an internist at Cambridge Health Alliance in Somerville, Mass.

. . .

Most older adults usually get enough nutrition from their food. But as you age, your requirements for some nutrients increase while your ability to absorb them and your appetite can diminish, so your doctor may recommend a supplement. Older adults may have trouble absorbing vitamin B12, for example. And you may need a calcium and vitamin D supplement if you’re at risk for bone loss, Dr. Manson said.

. . .

Several recent trials have also found that multivitamins may improve memory and slow cognitive decline in older adults, though more research is needed, Dr. Manson said.

And there’s some evidence that taking a supplement that contains vitamins C and E, zinc, copper, lutein and zeaxanthin (called an AREDS supplement) can slow vision loss for those with age-related macular degeneration, Dr. Manson said.

. . .

If you do purchase supplements, look for a certification seal from a trusted third party organization such as the U.S. Pharmacopeia or NSF, which confirm that the products contain the ingredients listed on the label.
