“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.

Australian Night Parrot Found Alive After Thought Extinct for 140 Years

(p. D3) Depending on whom you ask, the Tasmanian tiger or thylacine has either been extinct for nearly a century or has been just really good at hiding.

Now new research examining hundreds of reports from more than a century shows there is a good chance the thylacine may have persisted for a few decades longer in the most remote parts of Tasmania.

“There are pockets where the species could have maintained small populations,” said Barry Brook, a professor of environmental sustainability at the University of Tasmania.

One of the problems with the thylacine, and extinction in general, is it’s hard to prove something is truly gone. Australia’s night parrot for instance, was thought to be extinct for 140 years until its recent rediscovery.

. . .

For a study published . . . [online on March 18, 2023 [sic]] in the journal Science of the Total Environment, Dr. Brook’s team studied 1,237 Tasmanian tiger reports from 1910 onward. It classified these reports in terms of credibility.

Life Was Resilient Even in the Face of Earth’s Greatest Disaster

(p. D2) The asteroid moved 24 times faster than a rifle bullet as it struck Earth some 66 million years ago. Its supersonic shock wave flattened trees across North and South America, and its heat wave sparked incomprehensibly large forest fires.

The event lofted so much debris into the atmosphere that photosynthesis shut down. The non-avian dinosaurs disappeared. And nearly 75 percent of all species were extinguished.

. . .

But even at ground zero, life managed to return, and quickly.

New findings published in the journal Geology . . . [online on January 17, 2020 [sic]] revealed that cyanobacteria — blue-green algae responsible for harmful toxic blooms — moved into the crater a few years after the impact.

Humans’ Adaptive, Flexible Intelligence Evolved Where Climate “Change Was Dramatic, Frequent, Unpredictable and Stressful”

(p. C9) In “Origins: How Earth’s History Shaped Human History,” astrobiologist and professor of science communication Lewis Dartnell argues that “there is a clear causal chain taking us from the politics and socio-economic conditions of today, to their roots in historical agricultural systems, and then further back to the geological tapestry of the ground beneath our feet.”

. . .

The final sentence he offers as summation—“The Earth made us”—can be read two ways, capturing the parallel themes of “Origins.”

With emphasis on “us,” it refers to the origin of the genus Homo, a clade of naked apes giving rise to our species, H. sapiens, the greatest biological superpower of all time, one so potent that all others in our genus are extinct. Why did this emergence take place in the cradle of the East African Rift and nowhere else? And why did the arrival of our genus broadly coincide with the onset of high-frequency climatic swings about two million years ago? Mr. Dartnell concludes that this recently uplifted and intricately rifted landscape created a mosaic of habitats dominated by lakes that further amplified the climatic oscillations between dry-wet and hot-cool conditions. Change was dramatic, frequent, unpredictable and stressful. Thus “intelligence” became “the evolutionary solution to the problem of an environment that shifts faster than natural selection can adapt the body . . . driving . . . ever more flexible and intelligent behavior.”

Crowdsourced Data on Elephants’ Response to Death

(p. D2) It was 2013 when Sanjeeta Pokharel first witnessed Asian elephants responding to death. An older female elephant in an Indian park had died of an infection. A younger female was walking in circles around the carcass.

. . .

For a paper published Wednesday [May 18, 2022 [sic]] in the journal Royal Society Open Science, the scientists used YouTube to crowdsource videos of Asian elephants responding to death. They found reactions that included touching and standing guard as well as nudging, kicking and shaking. In a few cases, females had even used their trunks to carry calves, or baby elephants, that had died.

. . .

Combing through YouTube, the researchers found 24 cases for study.

“Nature Is So Beautiful, but Also Resilient”

(p. D2) Just after dawn on May 5 [2022], scientists working along a stretch of the Mekong River in Cambodia released a giant, endangered freshwater stingray that had been caught on a fisherman’s line. At 13 feet long and 400 pounds, the gigantic animal pancake was larger than a hibachi table.

“It was shaking, and I told her, ‘Calm down, we will release you soon,’” said Chea Seila, a coordinator for the Wonders of the Mekong Project.

. . .

That a stingray of this size could still be found in these waters was extraordinary, the experts said.

“It shows you nature is so beautiful, but also resilient,” said Sudeep Chandra, a limnologist at the University of Nevada, Reno and co-scientist on the Wonders of the Mekong Project. “Even with the major environmental problems in the Lower Mekong, like dams, forest change and overfishing, these large, charismatic species are still there, wanting to persist.”

Among Hoofed Mammals Outsiders Are More Likely to Innovate

(p. D2) Fair or not, goats have not earned a reputation for their problem-solving abilities.  . . .  But if you hide food in a strange cup and put a lid on it, a goat may find a way, a new study finds. And not just any goat, a team of researchers says. Animals that functioned like outsiders in their social group were best at tackling and solving a problem.

. . .

Mr. Caicoya and his colleagues looked at 13 species of hoofed mammals, with their study totaling 111 individuals living in zoos in Spain and Germany.

In a study published on Wednesday [April 12, 2023] in the Proceedings of the Royal Society B, Mr. Caicoya and his colleagues reported that around 38 percent of the animals avoided the cups entirely.

. . .

They found that animals that were outcasts or low in the pecking order had less fear of new objects, more willingness to explore them and a greater chance of getting the prize.

. . .

“The ones that are on the margins of the groups are the ones that are eating less and have more problems surviving in nature,” Mr. Caicoya said speculatively, “so those are the ones that normally take more risks to get food.”

Necessity, perhaps, is the mother of innovation.

Prime Minister Robert Peel Lost His Job for Supporting Repeal of the Corn Laws, but Advanced Britain’s Middle-Class

(p. C11) Simon Heffer’s “High Minds” is a deep, droll and lucid exploration of Britain’s intellectual and political life from 1837, when the young Queen Victoria ascended the throne of a chaotic, semifeudal society, to 1880, by which time Victoria was a widow and the Empress of India, and the British, apart from those at the very top and bottom of society, had bootstrapped themselves into sobriety and “respectability.”

. . .

The “crucial step” in the middle-class advance, Mr. Heffer writes, was the repeal of the Corn Laws in 1846. Opening the ports to foreign grain pacified the workers by lowering the price of bread. It hobbled the aristocracy by cutting the value of land, their biggest asset. And it geared economic policy to the commercial classes. A “long-term realignment” in politics followed. Repeal was secured by a Tory prime minister, Robert Peel, in alliance with free-market Whigs. It cost Peel his job but, over the next two decades, the Whigs turned into the Liberals, the party of middle-class reform.
