Three Cups of Coffee a Day Lowers Risk of Death

(p. D6) That morning cup of coffee may be linked to a lower risk of dying, researchers from a study published Monday [June 6, 2022] in The Annals of Internal Medicine concluded. Those who drank 1.5 to 3.5 cups of coffee per day, even with a teaspoon of sugar, were up to 30 percent less likely to die during the study period than those who didn’t drink coffee. Those who drank unsweetened coffee were 16 to 21 percent less likely to die during the study period, with those drinking about three cups per day having the lowest risk of death when compared with noncoffee drinkers.

Researchers analyzed coffee consumption data collected from the U.K. Biobank, a large medical database with health information from people across Britain. They analyzed demographic, lifestyle and dietary information collected from more than 170,000 people between the ages of 37 and 73 over a median follow-up period of seven years. The mortality risk remained lower for people who drank both decaffeinated and caffeinated coffee. The data was inconclusive for those who drank coffee with artificial sweeteners.

“It’s huge. There are very few things that reduce your mortality by 30 percent,” said Dr. Christina Wee, an associate professor of medicine at Harvard Medical School and a deputy editor of the scientific journal where the study was published. Dr. Wee edited the study and published a corresponding editorial in the same journal.

. . .

The study showed that the benefits of coffee tapered off for people who drank more than 4.5 cups of coffee each day.

CDC’s “Rigid Checklist” Leads Doctors to Misdiagnose Atypical Cases

(p. A17) In his “memoir of illness and discovery,” Mr. Douthat tells us of his descent into a netherworld of consternation, paranoia and despair after contracting a chronic form of Lyme disease six years ago. Although he experienced physical pain that was often unbearable, he was stonewalled and scoffed at by skeptical doctors who refused to accept the existence of a long-lingering form of Lyme.

. . .

Lyme—a debilitating bacterial disease acquired from deer-tick bites—was ruled out because many of his symptoms didn’t match a rigid checklist drawn up for the ailment by the Centers for Disease Control and Prevention. This “diagnostic standardization,” Mr. Douthat writes, was “supposed to establish a consistent baseline for national case reporting, not rule out the possibility of atypical cases or constrain doctors from diagnosing them.” As a result of such inflexibility, he tells us, doctors miss “anywhere from a third to half of early Lyme cases.”

Brynjolfsson Made “Long Bet” with Gordon that A.I. Will Increase Productivity

(p. B1) For years, it has been an article of faith in corporate America that cloud computing and artificial intelligence will fuel a surge in wealth-generating productivity. That belief has inspired a flood of venture funding and company spending. And the payoff, proponents insist, will not be confined to a small group of tech giants but will spread across the economy.

It hasn’t happened yet.

Productivity, which is defined as the value of goods and services produced per hour of work, fell sharply in the first quarter this year, the government reported this month. The quarterly numbers are often volatile, but the report seemed to dash earlier hopes that a productivity revival was finally underway, helped by accelerated investment in digital technologies during the pandemic.

The growth in productivity since the pandemic hit now stands at about 1 percent annually, in line with the meager rate since 2010 — and far below the last stretch of robust improvement, from 1996 to 2004, when productivity grew more than 3 percent a year.

. . .

(p. B6) The current productivity puzzle is the subject of spirited debate among economists. Robert J. Gordon, an economist at Northwestern University, is the leading skeptic. Today’s artificial intelligence, he says, is mainly a technology of pattern recognition, poring through vast troves of words, images and numbers. Its feats, according to Mr. Gordon, are “impressive but not transformational” in the way that electricity and the internal combustion engine were.

Erik Brynjolfsson, director of Stanford University’s Digital Economy Lab, is the leader of the optimists’ camp. He confesses to being somewhat disappointed that the productivity pickup is not yet evident, but is convinced it is only a matter of time.

“Real change is happening — a tidal wave of transformation is underway,” Mr. Brynjolfsson said. “We’re seeing more and more facts on the ground.”

It will probably be years before there is a definitive answer to the productivity debate. Mr. Brynjolfsson and Mr. Gordon made a “long bet” last year, with the winner determined at the end of 2029.

Young Despairing Chinese Adopt the “Run Philosophy”

(p. B1) “I can’t stand the thought that I will have to die in this place,” said Cheng Xinyu, a 19-year-old writer in the southwestern Chinese city of Chengdu, who is thinking of migrating to foreign countries before the government’s iron fist falls on her.

She can’t imagine having children in China, either.

“I like children, but I don’t dare to have them here because I won’t be able to protect them,” she said, citing concerns like pandemic control workers breaking into apartments to spray disinfectant, killing pets and requiring residents to leave the keys in their apartment door locks.

Ms. Cheng is part of a new trend known as the “run philosophy,” or “runxue,” that preaches running away from China to seek a safer and brighter future. She and millions of others also reposted a video in which a young man pushed back against police officers who warned that his family would be punished for three generations if he refused to go to a quarantine camp. “This will be our last generation,” he told the police.

His response became an online meme that was later censored. Many young people identified with the sentiment, saying they would be reluctant to have children under the increasingly authoritarian government.

. . .

(p. B3) The “run philosophy” and the “last generation” are the rallying cries for many Chinese in their 20s and 30s who despair about their country and their future. They are entering the labor force, getting married and deciding whether to have children in one of the country’s bleakest moments in decades. Censored and politically suppressed, some are considering voting with their feet while others want to protest by not having children.

. . .

Doris Wang, a young professional in Shanghai, said she had never planned to have children in China. Living through the harsh lockdown in the past two months reaffirmed her decision. Children should be playing in nature and with one another, she said, but they’re locked up in apartments, going through rounds of Covid testing, getting yelled at by pandemic control workers and listening to stern announcements from loudspeakers on the street.

“Even adults feel very depressed, desperate and unhealthy, not to mention children,” she said. “They’ll definitely have psychological issues to deal with when they grow up.” She said she planned to migrate to a Western country so she could have a normal life and dignity.

Compounding the frustrations, headlines are full of bad news about jobs. There will be more than 10 million college graduates in China this year, a record. But many businesses are laying off workers or freezing head counts as they try to survive the lockdowns and regulatory crackdowns.

. . .

“When you find that as an individual you have zero ability to fight back the state apparatus, your only way out is to run,” said Ms. Wang, the young professional in Shanghai.

Sri Lankan Ban on Synthetic Fertilizer Causes Soaring Food Prices and Hunger

(p. A17) The Green Revolution of Norman Borlaug, the American agronomist who did more to feed the world than any man before or since, set Sri Lanka on the path to agricultural abundance in 1970. It was built around chemical fertilizers and crops bred to be disease-resistant. Fifty-two years later, Sri Lanka has pulled off a revolution that is “antigreen” in the modern sense, toppling its president, Gotabaya Rajapaksa. In an uprising that has its roots in Mr. Rajapaksa’s imperious decision to impose organic farming on the entire country—which led to widespread hunger after the agricultural economy collapsed—Sri Lanka’s people have wrought the first contra-organic national uprising in history.

. . .

. . ., Mr. Rajapaksa was driven from office in part because he was an overzealous green warrior, who imposed on his countrymen a policy that the American environmental left holds sacred.

. . .

. . ., Mr. Rajapaksa took a step that poleaxed Sri Lanka. On April 27, 2021—with no warning, and with no attempt to teach farmers how to cope with the change—he announced a ban on all synthetic fertilizers and pesticides. Henceforth, he decreed, Sri Lankan agriculture would be 100% organic. Agronomists and other scientists warned loudly of the catastrophe that would ensue, but they were ignored. This Sri Lankan Nero listened to no one.

. . .

What happened next? Rice production fell by 20% in the first 180 days of the ban on synthetic fertilizer. Tea, Sri Lanka’s main cash crop, has been hit hard, with exports at their lowest level in nearly a quarter-century. Whether from indignation over the new laws or an inability to go organic, farmers left a third of all farmland fallow. Food prices soared as a result of scarcity and Sri Lanka’s people, their pockets already hit by the pandemic, began to go hungry. To add to the stench of failure, a shipload of manure from China had to be turned back after samples revealed dangerous levels of bacteria. The farmers had no synthetic fertilizer, and hardly any of the organic kind.

Despite Global Warming, “Largest Gathering of Fin Whales Ever Documented” in “Thrilling” Return to Ancestral Antarctic Waters

(p. A5) From a distance, it looked like thick fog across the horizon. But as the ship drew closer, the ocean bubbled as 150 fin whales, the planet’s second-largest creatures, dived and lunged against the water’s surface.

Six weeks into a nine-week expedition, near the coast of Elephant Island, northeast of the Antarctic Peninsula, researchers had stumbled upon the largest gathering of fin whales ever documented.

“It was one of the most spectacular observations I’ve had,” said Helena Herr, a marine mammal ecologist at the University of Hamburg. “The fin whales seemed to go crazy because of the food load they were confronted with. It was absolutely thrilling.”

Dr. Herr and her colleagues documented the return of large numbers of fin whales to the waters that once made up their historical feeding grounds in a paper published on Thursday [July 7, 2022] in the journal Scientific Reports.

. . .

In the oceans, recent modeling has estimated that global warming caused by continued greenhouse gas emissions could trigger a mass die-off of marine species by 2300.

The rebounding of the fin whales’ population, however, offers “a sign that if you enforce management and conservation, there are chances for species to recover,” Dr. Herr said.

. . .

Scientists are not sure why some of the gatherings were so large. Dr. Herr noted that the scenes they witnessed had at least some parallels to historical reports written before widespread commercial whaling. For instance, the naturalist William Speirs Bruce described seeing whales’ backs and blasts stretching “from horizon to horizon” on an Antarctic expedition in 1892.

Recent research has proposed that the rebound in whale populations is good not only for the whales but also for the entire ecosystem, through a concept known as the “whale pump.” Scientists posit that as whales feed on krill, they excrete iron, which was locked in the crustaceans, back into the water. That, in turn, can boost phytoplankton, microscopic organisms that use carbon dioxide in photosynthesis and serve as the base of the marine food chain.

As the fin whales bring the krill to the water’s surface, they can also facilitate the success of other predators, including seabirds, and seals, Dr. Santora said. “There’s much more cooperation and symbiosis than we usually give the ecosystem credit for.”

Log4j Open Source Bug Created “Endemic” Risk for “a Decade or Longer”

Continuing worries about the Log4j software bug are consistent with my skepticism of open source software, Openness to Creative Destruction. You can find a brief discussion in the chapter defending patents.

(p. A6) WASHINGTON—A major cybersecurity bug detected last year in a widely used piece of software is an “endemic vulnerability” that could persist for more than a decade as an avenue for hackers to infiltrate computer networks, a U.S. government review has concluded.

. . .

“The Log4j event is not over,” the report said. “The board assesses that Log4j is an ‘endemic vulnerability’ and that vulnerable instances of Log4j will remain in systems for many years to come, perhaps a decade or longer. Significant risk remains.”

. . .

Security researchers uncovered last December a major flaw in Log4j, an open-source software logging tool. It is a widely used piece of free code that logs activity in computer networks and applications.

Insurers Claim Curing Obesity Is “Vanity”

(p. A17) Maya Cohen’s entree into the world of obesity medicine came as a shock.

In despair over her weight, she saw Dr. Caroline Apovian, an obesity specialist at Brigham and Women’s Hospital, who prescribed Saxenda, a recently approved weight-loss drug. Ms. Cohen, who is 55 and lives in Cape Elizabeth, Maine, hastened to get it filled.

Then she saw the price her pharmacy was charging: $1,500 a month. Her insurer classified it as a “vanity drug” and would not cover it.

“I’m being treated for obesity,” she complained to her insurer, but to no avail.

. . .

More than 40 percent of Americans have obesity, and most have tried repeatedly to lose weight and keep it off, only to fail. Many suffer from medical conditions that are linked to obesity, including diabetes, joint and back pain and heart disease, and those conditions often improve with weight loss.

“The evidence is now overwhelming that there are physical changes in weight regulating pathways that make it difficult for people to lose weight and maintain their weight loss,” said Dr. Louis Aronne, an obesity medicine specialist who directs the comprehensive weight control center at Weill Cornell Medicine. “It’s not that they don’t have willpower. Something physical is holding them back.”

. . .

“Access to medicines for the treatment of obesity is dismal in this country,” said Dr. Fatima Cody Stanford, an obesity medicine specialist at Massachusetts General Hospital and Harvard Medical School.

. . .

Douglas Langa, an executive vice president at Novo Nordisk, . . . said that diabetes and obesity were “separate categories, separate marketplaces” to explain the difference in price between the companies’ two drugs that were based on the same medicine, semaglutide. He said Wegovy’s price “reflects efficacy and clinical value in this area of unmet need.”

Dr. Stanford was appalled.

“It’s unbelievable,” she said, adding that it was a gross inequity to charge people more for the same drug because of their obesity. She finds herself in an untenable situation: getting excited when her patients with obesity also have diabetes because their insurers pay for the drug.

Entrepreneur Turns Invasive Predator Crabs into Tasty Whiskey

(p. A12) CONCORD, N.H. — Care for a hint of crab in your whiskey?

A New Hampshire distillery has come up with its newest concoction called “Crab Trapper” – whiskey flavored with invasive green crabs.

Tamworth Distilling, a maker of craft spirits, is not afraid of pushing boundaries with unexpected flavors. In the past, the distillery produced a whiskey with the secretion from beavers’ castor sacs. Last year, it was turkey over the holidays and before that the notoriously pungent smell of durian.

The company said the body of this peculiar brew has hints of maple, vanilla oak, clove, cinnamon and allspice.

. . .

Searching for a fresh flavor, Tamworth Distilling cast its eye to the sea. Distiller Matt Power said the company heard about the problems caused by the invasive green crabs from the University of New Hampshire Extension’s Gabriela Bradt.

. . .

Bradt, a fisheries extension specialist, said the crabs are “so numerous that they have really impacted shellfish habitats and fisheries because they are also voracious predators.” A good example, she said, was the soft-shell clam fishery, which has suffered millions of dollars in losses.

. . .

The distillery’s sales manager, Jillian Anderson, said the whiskey, available on site, at Philadelphia’s Art in the Age and online, has grown in popularity.

Is Apple’s Lack of New Breakthroughs Due to Lack of Opportunity or Lack of Steve Jobs?

(p. 15) Steve Jobs, Apple’s co-founder and animating spirit, died in 2011, leaving the firm in the hands of Jony Ive, the British-born designer-savant, and Tim Cook, a child of Alabama who’d become a master of supply chains and production costs. “After Steve,” by the New York Times reporter Tripp Mickle, covers Ive’s and Cook’s careers, and how they and the company changed after they took over.

. . .

In the epilogue, Mickle drops his reporter’s detachment to apportion responsibility for the firm’s failure to launch another transformative product. Cook is blamed for being aloof and unknowable, a bad partner for Ive, “an artist who wanted to bring empathy to every product.” Ive is also dinged for taking on “responsibility for software design and the management burdens that he soon came to disdain.” By the end, the sense that the two missed a chance to create a worthy successor to the iPhone is palpable.

It’s also hooey, and the best evidence for that is the previous 400 pages. It’s true that after Jobs died, Apple didn’t produce another device as important as the iPhone, but Apple didn’t produce another device that important before he died either. It’s also true that Cook did not play the role of C.E.O. as Jobs had, but no one ever thought he could, including Jobs, who on his deathbed advised Cook never to ask what Steve would do: “Just do what’s right.”

Ive and Cook wanted another iPhone, but, as Mickle’s exhaustive reporting makes clear, there was not another such device to be made. Self-driving cars were too hard, health devices too regulated, television protected in ways music had not been, and even the earbuds and watch, devices they actually shipped, were peripheral, technically and conceptually, to Apple’s greatest product.

Epilogue aside, the book is an amazingly detailed portrait of the permanent tension between strategy and luck: Companies make their own history, but they do not make it as they please. What happened after Steve was that Cook’s greatest opportunities were in Apple’s future, Ive’s in its past.

Cerebrospinal Fluid From Young Mice Improves the Memories of Old Mice

(p. D3) Five years ago, Tal Iram, a young neuroscientist at Stanford University, approached her supervisor with a daring proposal: She wanted to extract fluid from the brain cavities of young mice and to infuse it into the brains of older mice, testing whether the transfers could rejuvenate the aging rodents.

. . .

Dr. Iram persevered, working for a year just to figure out how to collect the colorless liquid from mice. On Wednesday [May 11, 2022], she reported the tantalizing results in the journal Nature: A week of infusions of young cerebrospinal fluid improved the memories of older mice.

. . .

Cerebrospinal fluid made for a logical target for researchers interested in aging. It nourishes brain cells, and its composition changes with age. Unlike blood, the fluid sits close to the brain.

But for years, scientists saw the fluid largely as a way of recording changes associated with aging, rather than countering its effects. Tests of cerebrospinal fluid, for example, have helped to identify levels of abnormal proteins in patients with significant memory loss who went on to develop Alzheimer’s disease.

. . .

“This is a very cool study that looks scientifically solid to me,” said Matt Kaeberlein, a biologist who studies aging at the University of Washington and was not involved in the research. “This adds to the growing body of evidence that it’s possible, perhaps surprisingly easy, to restore function in aged tissues by targeting the mechanisms of biological aging.”

Dr. Iram tried to determine how the young cerebrospinal fluid was helping to preserve memory by analyzing the hippocampus, a portion of the brain dedicated to memory formation and storage. Treating the old mice with the fluid, she found, had a strong effect on cells that act as precursors to oligodendrocytes, which produce layers of fat known as myelin that insulate nerve fibers and ensure strong signal connections between neurons.

The authors of the study homed in on a particular protein in the young cerebrospinal fluid that appeared involved in setting off the chain of events that led to stronger nerve insulation. Known as fibroblast growth factor 17, or FGF17, the protein could be infused into older cerebrospinal fluid and could partially replicate the effects of young fluid, the study found.

Even more strikingly, blocking the protein in young mice appeared to impair their brain function, offering stronger evidence that FGF17 affects cognition and changes with age.

. . .

But Dr. Wyss-Coray said that the study filled a critical gap in the understanding of how the brain’s environment changes as people age.

“The question is, ‘How can you maintain cognitive health until you die? How can you make the brain resilient to this relentless degeneration of the body?’” he said, “and what a growing number of studies show is that as we learn more about the aging process itself, maybe we can slow down aspects of aging and maintain tissue integrity or even rejuvenate tissues.”
