History’s Largest Mining Operation Is About to Begin

Wil S. Hylton at The Atlantic:

At full capacity, these companies expect to dredge thousands of square miles a year. Their collection vehicles will creep across the bottom in systematic rows, scraping through the top five inches of the ocean floor. Ships above will draw thousands of pounds of sediment through a hose to the surface, remove the metallic objects, known as polymetallic nodules, and then flush the rest back into the water. Some of that slurry will contain toxins such as mercury and lead, which could poison the surrounding ocean for hundreds of miles. The rest will drift in the current until it settles in nearby ecosystems. An early study by the Royal Swedish Academy of Sciences predicted that each mining ship will release about 2 million cubic feet of discharge every day, enough to fill a freight train that is 16 miles long. The authors called this “a conservative estimate,” since other projections had been three times as high. By any measure, they concluded, “a very large area will be blanketed by sediment to such an extent that many animals will not be able to cope with the impact and whole communities will be severely affected by the loss of individuals and species.”

The Art of Dying

Peter Schjeldahl at The New Yorker:

Lung cancer, rampant. No surprise. I’ve smoked since I was sixteen, behind the high-school football bleachers in Northfield, Minnesota. I used to fear the embarrassment of dying youngish, letting people natter sagely, “He smoked, you know.” But at seventy-seven I’m into the actuarial zone.

I know about ending a dependency. I’m an alcoholic twenty-seven years sober. Drink was destroying my life. Tobacco only shortens it, with the best parts over anyway.

I got the preliminary word from my doctor by phone while driving alone upstate from the city to join my wife, Brooke, at our country place. After the call, I found myself overwhelmed by the beauty of the passing late-August land. At mile eighty-one of the New York State Thruway, the gray silhouettes of the Catskills come into view, perfectly framed and proportioned. How many times had I seen and loved the sight? How many more times would I? I thought of Thomas Cole’s paintings, from another angle, of those very old, worn mountains, brooding on something until the extinction of matter.

Debbie Harry

Jenny Turner at the LRB:

One great thing about Harry in Blondie was exactly this tension: she could look and sound so sweet and doll-like, but she was obviously and unapologetically a woman with a past. Another was the dynamic she had, so pale and starry, with her dark-haired, bridge-and-tunnelly band. Her outfits helped too, weird shapes and garish colours in nasty synthetic fabrics that looked like they came – and from what the book says, probably did – from a bargain bin in the Bowery: the big shirt that kept falling off the shoulder, what with all the awkward dancing; the harsh turquoise suit and shirt and tie; the ripply grey one-armed chiffon, worn with mules and thick black tights. The hair kept changing, though it was always blonde and afloat with static, stripped and dyed within an inch of its life. Sometimes it was big and thick and exhausting-looking. Sometimes it was shorter and lighter, in a bob. Usually you saw roots, a thick black skunk-stripe even. ‘Being a bleached blonde for so many years,’ Harry writes, ‘has made me acutely aware of what healthy hair looks like.’ There’s a picture in the book of a family Christmas in New Jersey, with her hair in its undyed colour, a plain, flat brown.

Memories Can Be Injected and Survive Amputation and Metamorphosis

Marco Altamirano in Nautilus:

The study of memory has always been one of the stranger outposts of science. In the 1950s, an unknown psychology professor at the University of Michigan named James McConnell made headlines—and eventually became something of a celebrity—with a series of experiments on freshwater flatworms called planaria. These worms fascinated McConnell not only because they had, as he wrote, a “true synaptic type of nervous system” but also because they had “enormous powers of regeneration…under the best conditions one may cut [the worm] into as many as 50 pieces” with each section regenerating “into an intact, fully-functioning organism.”

In an early experiment, McConnell trained the worms à la Pavlov by pairing an electric shock with flashing lights. Eventually, the worms recoiled to the light alone. Then something interesting happened when he cut the worms in half. The head of one half of the worm grew a tail and, understandably, retained the memory of its training. Surprisingly, however, the tail, which grew a head and a brain, also retained the memory of its training. If a headless worm can regrow a memory, then where is the memory stored, McConnell wondered. And, if a memory can regenerate, could he transfer it?

Artificial intelligence identifies previously unknown features associated with cancer recurrence

From Phys.Org:

Artificial intelligence (AI) technology developed by the RIKEN Center for Advanced Intelligence Project (AIP) in Japan has successfully found features in pathology images from human cancer patients, without annotation, that could be understood by human doctors. Further, the AI identified features relevant to cancer prognosis that were not previously noted by pathologists, leading to a higher accuracy of prostate cancer recurrence compared to pathologist-based diagnosis. Combining the predictions made by the AI with predictions by human pathologists led to an even greater accuracy. According to Yoichiro Yamamoto, the first author of the study published in Nature Communications, “This technology could contribute to personalized medicine by making highly accurate prediction of cancer recurrence possible by acquiring new knowledge from images. It could also contribute to understanding how AI can be used safely in medicine by helping to resolve the issue of AI being seen as a ‘black box.'”

The research group led by Yamamoto and Go Kimura, in collaboration with a number of university hospitals in Japan, adopted an approach called “unsupervised learning.” As long as humans teach the AI, it is not possible to acquire knowledge beyond what is currently known. Rather than being “taught” medical knowledge, the AI was asked to learn using unsupervised deep neural networks, known as autoencoders, without being given any medical knowledge. The researchers developed a method for translating the features found by the AI—only numbers initially—into high-resolution images that can be understood by humans.

Scattering a Mother’s Ashes: On Grief, Intimacy, and Renewal

William Pierce in Literary Hub:

Dad called us, Thom and me, into the office. Its bifold louvre doors opened just behind my dining chair. He showed us the safe deposit key again. He showed us his will again. He showed us the folders of information about the condo in Florida, about his car, the binders of account statements, his credit cards, his social security, pension, and insurance policies. Part of me resisted.

And then he sprang a big one on us: he wanted to spread Mom’s ashes today. She wanted half to be spread in the gardens, and half at Jones Beach, where as a child she’d gone with her mother and sister nearly every summer day. That sun exposure, when she was immunosuppressed years later, had given her nearly twenty lesions a month, across her arms, legs, neck, and face, that her dermatologist would burn and freeze off: squamous, pre-squamous, and twice—jobs too dire for that simple burning—melanomas on her face.

Sean Carroll’s Mindscape Podcast: Azra Raza on The Way We Should Fight Cancer

Sean Carroll in Preposterous Universe:

In the United States, more than one in five deaths is caused by cancer. The medical community has put enormous resources into fighting this disease, yet its causes and best treatments continue to be a puzzle. Azra Raza has been on both sides of the patient’s bed, as she puts it — both as an oncologist and expert in the treatment of Myelodisplastic Syndrome (MDS), and as a wife who lost her husband to cancer. In her new book, The First Cell, she argues that we have placed too much emphasis on treating cancer once it has already developed, and not nearly enough on catching it as soon as possible. We talk about what cancer is and why it’s such a difficult disease to understand, as well as discussing how patients and their loved ones should face up to the challenges of dealing with cancer.

The biggest story in the UK is not Brexit. It’s life expectancy

Danny Dorling in The Correspondent:

The numbers of people dying, week in, week out, tell us more about the four countries of the UK than we could ever hope to learn from the attention given to Brexit. This is a kingdom falling apart.

I’m a geographer who has been studying mortality records in the UK The data I review both yearly and weekly has given me a perspective on British society often missed when following the political circus.

In early 2014, trying to highlight that the fact that something very unusual was happening: 

The following year, there was a huge rise in deaths. The numbers were released

Liberalism at Large: The World according to the Economist

William Keegan at Literary Review:

As the title indicates, this is a book about liberalism and The Economist’s propagation of it. But as the great Professor Joad would have said, ‘It all depends what you mean by liberalism.’ These days there is much talk of the differences between political liberalism, economic liberalism and social liberalism. In the 19th century, when The Economist was establishing its reputation, its commitment to free trade and capitalism was such that, with regard to the humanitarian 1844 Factory Act, it could opine: ‘the more it is investigated, the more we are compelled to acknowledge that in any interference with industry and capital, the law is powerful only for evil, but utterly powerless for good.’

Zevin points out that, from the Crimean War to the present day, The Economist has championed ‘liberal imperialism’, to the point where one of its journalists felt able to come out in a farewell speech with the crack that, in all his time there, The Economist ‘never saw a war it didn’t like’.

On The Curiously Self-Tortured Legacy of Post-Grunge Music

Eli Zeger at The Baffler:

Godsmack is part of an aggressive, no-cowards-allowed milieu of hard rock known as “post-grunge” (or pejoratively “butt rock”), which was at its most lucrative during the late 1990s and throughout the aughts, when it dominated both the rock and pop charts. Obscuring the stylistic boundaries between neighboring genres—country, grunge, and the genre which grunge supposedly killed, hair metal—post-grunge is characterized by its dragging tempos, down-tuned chord progressions, sporadic twanginess, and overly passionate vocals. If you took an eighties power ballad’s major key and turned it minor, you’d have a post-grunge song more or less. Even today, as its pop appeal has vanished, it remains viable in the realm of mainstream rock, selling out amphitheaters and filling up the playlists on “Alt Nation”-type stations. It soundtracks WWE pay-per-views; it’s what plays over the loudspeakers in Six Flags food courts.

Edna O’Brien: “Some Men Like Fairly Trivial Women”

Kate Mossman at The New Statesman:

It is unusual to find a writer of 88 embarking on a dramatic change of style and taking pains to justify it, but O’Brien still cares what people think. The week we met, she’d won the David Cohen Prize for Literature, a major recognition of a lifetime’s work which has, for other winners, been followed by a Nobel Prize. But she is still stung by a New Yorker profile from October in which, over the course of 10,000 words, the staff writer Ian Parker took the decision to put under the microscope the colourful, heightened way she has told her life story. O’Brien remembered a preacher denouncing the provocative (some said “filthy”) The Country Girls in the pulpit of the church near her home in Tuamgraney, then burning it: Parker said no one in the village recalled the same. And her relationship with her mother may not have been as hostile as she’s made out, he suggested – Lena O’Brien speaks affectionately in much of their correspondence…

How Hallmark Took Over Cable Television

Sarah Larson in The New Yorker:

This year, Hallmark made headlines when it announced that it would produce two holiday movies with Hanukkah themes. In both, however, Christmas is the star. In “Holiday Date,” Brooke (Brittany Bristow) brings an actor, Joel (Matt Cohen), to Whispering Pines, her home town, for the holidays, to pose as her boyfriend—a common phenomenon on Hallmark, and perhaps less so in real life. One afternoon in September, I visited the set, in a house outside Vancouver. The downstairs was festooned with pine sconces, ornaments, and bows. “Tree on the move!” a crew member said. “I’ve never done Hallmark,” Cohen told me. For a decade, he’d played scary roles, including Lucifer, on shows like “Supernatural.” “I committed to the dark side and it paid the bills,” he said. “But this is who I really am. I’m a goofball.”

As “Holiday Date” unfolds, it’s revealed that Joel doesn’t know how to decorate a tree, or hang Christmas lights: he’s Jewish. The family is “surprised but unfazed,” Bristow explained. They incorporate latkes and a menorah into their festivities and teach Joel to deck the halls. “I’ve never celebrated Christmas, but I always wanted to,” he says. In the movie’s trailer, “Silent Night” plays in the background.

That afternoon, I watched as a scene was filmed in which Joel, handsome in a Santa-red sweater, helps Brooke’s young niece, Tessa (Ava Grace Cooper), rehearse for a Christmas pageant. On the monitor, I could see three Christmas trees in the frame. Tessa’s self-absorbed parents, played by the recurring Hallmark bro Peter Benson and the Hallmark villain Anna Van Hooft, walked by, looking at their phones, and opened the front door, obscuring a tree but introducing a wreath. The living room was a riot of Yuletide splendor: trees and garlands. A fire roared in the fireplace, and a row of Christmas stockings hung on the mantel. Above them, a string of blue-and-white letters spelled out “happy hanukkah.” Tessa’s pageant line was about family togetherness: “ ’Cause that’s what Christmas is all about.” Cohen beamed. “Perfect,” he said.

The best science images of the year: 2019 in pictures

Gaind and Callaway in Nature:

2019 will be remembered as the year humanity captured the first-ever image of a black hole. The year also brought fresh views of some of Earth’s smallest living creatures and ominous signs of its changing climate. Here are the most striking shots from science and the natural world that caught the attention of Nature’s news team.

Tiny trumpets

Stentors — or trumpet animalcules — are a group of single-celled freshwater protozoa. This image won second prize in the 2019 Nikon Small World Photomicrography Competition, and was captured at 40 times magnification by researcher Igor Siwanowicz at the Howard Hughes Medical Institute’s Janelia Research Campus in Ashburn, Virginia.

Living Mirrors: Infinity, Unity, and Life in Leibniz’s Philosophy

Justin E. H. Smith in Notre Dame Philosophical Reviews:

There are several billion microorganisms in a typical teaspoon of soil: not an infinite number, but more than any finite mind could hope to count one by one. Leibniz did not know the precise nature of soil microbes, nor did he have any empirical proof of their existence, but he was convinced that they, or something like them, must exist, and this for deep philosophical reasons. Whatever there is in the world must be underlain by real soul-like unities or centers of action and perception, analogous to whatever it is we are referring to when we speak of “me”. But any such center of action must be outfitted with a body, and this body must be such that no amount of decomposition or removal of parts could ever take the being in question out of existence. Thus there is nothing in the physical world but what Leibniz called “organic bodies” or “natural machines”, that is to say infinitely complex mechanical bodies. Considered together with the active, perceiving unities that underlie them, these organic bodies are best described as “corporeal substances”, of which animals and plants are the varieties we here on the surface of the earth know best. Everything is alive, in short.

Leibniz got quite a bit right, though he was wrong about some of the details.

Revisiting Nuclear Close Calls Since 1945

Bruno Tertrais at the website of La Fondation pour la Recherche Stratégique:

Why have nuclear weapons not been used since 1945? The more time passes, the more the question becomes relevant and even puzzling for pessimists. Most strategists of the 1960s would be stunned to hear that as of 2017, there still has yet to be another nuclear use in anger. The prospects of a “nuclear weapons ban” or recurring proposals for “de-alerting”—instituting changes that can lengthen the time required to actually use the weapons—make the question even more relevant. Has mankind really stood “on the brink” several times since Nagasaki, and have we avoided nuclear catastrophe mostly because of pure “luck”? Recent books, articles, and reports, as well as two wide-audience documentaries, say yes.

This is not the case. The absence of any deliberate nuclear explosion (except for testing) since 1945 can simply be explained by human prudence and the efficiency of mechanisms devoted to the guardianship of nuclear weapons. Banning nuclear weapons may or may not be a good idea. But it should not be based on the myth of an inherently and permanently high risk of nuclear use.

The analysis that follows covers the deliberate use of nuclear weapons by a legitimate authority, either by error (“false alarm”) or not (“nuclear crisis”). It does not cover the risk of an accidental nuclear explosion, an unauthorized launch, or a terrorist act.3 It covers 37 different known episodes, including 25 alleged nuclear crises and twelve technical incidents, which have been mentioned in the literature to one degree or another as potentially dangerous.

The mafia is language and symbols

Roberto Saviano in the New York Review of Books:

Stills from news footage of ’Ndrangheta boss Giuseppe ‘The Goat’ Giorgi during his arrest, showing him greeting local men and having his hand kissed in a typical mafia gesture of respect, San Luca, Calabria, June 2017

People think the mafia is first and foremost violence, hit men, threats, extortion, and drug trafficking. But before all else, the mafia is language and symbols. Who doesn’t recall the opening scene of The Godfather, when Vito Corleone extends his hand to Bonasera, the Italian who has come to ask him a “favor,” and who reverently kisses the boss’s hand to ingratiate himself?

Such customs are not obsolete. In June 2017 Giuseppe “the Goat” Giorgi, a boss of the ’Ndrangheta (the Calabrian mafia) and one of Italy’s most dangerous criminals, was arrested. He had gone into hiding twenty-three years earlier, after being convicted of international drug trafficking and sentenced to twenty-eight years and nine months in prison. He was found above the fireplace of his family’s house, in a concealed space that opened by moving a stone in the floor, where he could hide in the event of searches while passing his fugitive days in the comfort of home. As the boss left the building under police escort, fellow villagers paid him tribute, one not only shaking his hand but kissing it.

Although hand-kissing is best known as a gallant way of greeting a lady, to kiss the knuckles of a man is a familiar gesture to anyone who, like me, grew up in southern Italy.

What’s next for psychology’s embattled field of social priming

Tom Chivers in Nature:

Three years ago, a team of psychologists challenged 180 students with a spatial puzzle. The students could ask for a hint if they got stuck. But before the test, the researchers introduced some subtle interventions to see whether these would have any effect. The psychologists split the volunteers into three groups, each of which had to unscramble some words before doing the puzzle. One group was the control, another sat next to a pile of play money and the third was shown scrambled sentences that contained words relating to money. The study, published this June1, was a careful repeat of a widely cited 2006 experiment2. The original had found that merely giving students subtle reminders of money made them work harder: in this case, they spent longer on the puzzle before asking for help. That work was one among scores of laboratory studies which argued that tiny subconscious cues can have drastic effects on our behaviour. Known by the loosely defined terms ‘social priming’ or ‘behavioural priming’, these studies include reports that people primed with ‘money’ are more selfish2; that those primed with words related to professors do better on quizzes3; and even that people exposed to something that literally smells fishy are more likely to be suspicious of others4. The most recent replication effort1, however, led by psychologist Doug Rohrer at the University of South Florida in Tampa, found that students primed with ‘money’ behave no differently on the puzzle task from the controls.

It is one of dozens of failures to verify earlier social-priming findings. Many researchers say they now see social priming not so much as a way to sway people’s unconscious behaviour, but as an object lesson in how shaky statistical methods fooled scientists into publishing irreproducible results. This is not the only area of research to be dented by science’s ‘replication crisis’. Failed replication attempts have cast doubt on findings in areas from cancer biology to economics. But so many findings in social priming have been disputed that some say the field is close to being entirely discredited.
