The new science of death: 'There's something happening in the brain that makes no sense... - 0 views

  • Jimo Borjigin, a professor of neurology at the University of Michigan, had been troubled by the question of what happens to us when we die. She had read about the near-death experiences of certain cardiac-arrest survivors who had undergone extraordinary psychic journeys before being resuscitated. Sometimes, these people reported travelling outside of their bodies towards overwhelming sources of light where they were greeted by dead relatives. Others spoke of coming to a new understanding of their lives, or encountering beings of profound goodness
  • Borjigin didn’t believe the content of those stories was true – she didn’t think the souls of dying people actually travelled to an afterworld – but she suspected something very real was happening in those patients’ brains. In her own laboratory, she had discovered that rats undergo a dramatic storm of many neurotransmitters, including serotonin and dopamine, after their hearts stop and their brains lose oxygen. She wondered if humans’ near-death experiences might spring from a similar phenomenon, and if it was occurring even in people who couldn’t be revived
  • when she looked at the scientific literature, she found little enlightenment. “To die is such an essential part of life,” she told me recently. “But we knew almost nothing about the dying brain.” So she decided to go back and figure out what had happened inside the brains of people who died at the University of Michigan neurointensive care unit.

  • Since the 1960s, advances in resuscitation had helped to revive thousands of people who might otherwise have died. About 10% or 20% of those people brought with them stories of near-death experiences in which they felt their souls or selves departing from their bodies
  • According to several international surveys and studies, one in 10 people claims to have had a near-death experience involving cardiac arrest, or a similar experience in circumstances where they may have come close to death. That’s roughly 800 million souls worldwide who may have dipped a toe in the afterlife.
  • In the 1970s, a small network of cardiologists, psychiatrists, medical sociologists and social psychologists in North America and Europe began investigating whether near-death experiences proved that dying is not the end of being, and that consciousness can exist independently of the brain. The field of near-death studies was born.
  • in 1975, an American medical student named Raymond Moody published a book called Life After Life.
  • Meanwhile, new technologies and techniques were helping doctors revive more and more people who, in earlier periods of history, would have almost certainly been permanently deceased.
  • “We are now at the point where we have both the tools and the means to scientifically answer the age-old question: What happens when we die?” wrote Sam Parnia, an accomplished resuscitation specialist and one of the world’s leading experts on near-death experiences, in 2006. Parnia himself was devising an international study to test whether patients could have conscious awareness even after they were found clinically dead.
  • Borjigin, together with several colleagues, took the first close look at the record of electrical activity in the brain of Patient One after she was taken off life support. What they discovered – in results reported for the first time last year – was almost entirely unexpected, and has the potential to rewrite our understanding of death.
  • “I believe what we found is only the tip of a vast iceberg,” Borjigin told me. “What’s still beneath the surface is a full account of how dying actually takes place. Because there’s something happening in there, in the brain, that makes no sense.”
  • Over the next 30 years, researchers collected thousands of case reports of people who had had near-death experiences
  • near-death studies was already splitting into several schools of belief, whose tensions continue to this day. One influential camp was made up of spiritualists, some of them evangelical Christians, who were convinced that near-death experiences were genuine sojourns in the land of the dead and divine
  • Moody was their most important spokesman; he eventually claimed to have had multiple past lives and built a “psychomanteum” in rural Alabama where people could attempt to summon the spirits of the dead by gazing into a dimly lit mirror.
  • It is no longer unheard of for people to be revived even six hours after being declared clinically dead. In 2011, Japanese doctors reported the case of a young woman who was found in a forest one morning after an overdose stopped her heart the previous night; using advanced technology to circulate blood and oxygen through her body, the doctors were able to revive her more than six hours later, and she was able to walk out of the hospital after three weeks of care
  • The second, and largest, faction of near-death researchers were the parapsychologists, those interested in phenomena that seemed to undermine the scientific orthodoxy that the mind could not exist independently of the brain. These researchers, who were by and large trained scientists following well established research methods, tended to believe that near-death experiences offered evidence that consciousness could persist after the death of the individua
  • Their aim was to find ways to test their theories of consciousness empirically, and to turn near-death studies into a legitimate scientific endeavour.
  • Finally, there emerged the smallest contingent of near-death researchers, who could be labelled the physicalists. These were scientists, many of whom studied the brain, who were committed to a strictly biological account of near-death experiences. Like dreams, the physicalists argued, near-death experiences might reveal psychological truths, but they did so through hallucinatory fictions that emerged from the workings of the body and the brain.
  • Between 1975, when Moody published Life After Life, and 1984, only 17 articles in the PubMed database of scientific publications mentioned near-death experiences. In the following decade, there were 62. In the most recent 10-year span, there were 221.
  • Today, there is a widespread sense throughout the community of near-death researchers that we are on the verge of great discoveries
  • “We really are in a crucial moment where we have to disentangle consciousness from responsiveness, and maybe question every state that we consider unconscious,”
  • “I think in 50 or 100 years time we will have discovered the entity that is consciousness,” he told me. “It will be taken for granted that it wasn’t produced by the brain, and it doesn’t die when you die.”
  • it is in large part because of a revolution in our ability to resuscitate people who have suffered cardiac arrest
  • In a medical setting, “clinical death” is said to occur at the moment the heart stops pumping blood, and the pulse stops. This is widely known as cardiac arrest
  • Loss of oxygen to the brain and other organs generally follows within seconds or minutes, although the complete cessation of activity in the heart and brain – which is often called “flatlining” or, in the case of the latter, “brain death” – may not occur for many minutes or even hours.
  • That began to change in 1960, when the combination of mouth-to-mouth ventilation, chest compressions and external defibrillation known as cardiopulmonary resuscitation, or CPR, was formalised. Shortly thereafter, a massive campaign was launched to educate clinicians and the public on CPR’s basic techniques, and soon people were being revived in previously unthinkable, if still modest, numbers.
  • scientists learned that, even in its acute final stages, death is not a point, but a process. After cardiac arrest, blood and oxygen stop circulating through the body, cells begin to break down, and normal electrical activity in the brain gets disrupted. But the organs don’t fail irreversibly right away, and the brain doesn’t necessarily cease functioning altogether. There is often still the possibility of a return to life. In some cases, cell death can be stopped or significantly slowed, the heart can be restarted, and brain function can be restored. In other words, the process of death can be reversed.
  • In his book, Moody distilled the reports of 150 people who had had intense, life-altering experiences in the moments surrounding a cardiac arrest. Although the reports varied, he found that they often shared one or more common features or themes. The narrative arc of the most detailed of those reports – departing the body and travelling through a long tunnel, having an out-of-body experience, encountering spirits and a being of light, one’s whole life flashing before one’s eyes, and returning to the body from some outer limit – became so canonical that the art critic Robert Hughes could refer to it years later as “the familiar kitsch of near-death experience”.
  • In 2019, a British woman named Audrey Schoeman who was caught in a snowstorm spent six hours in cardiac arrest before doctors brought her back to life with no evident brain damage.
  • That is a key tenet of the parapsychologists’ arguments: if there is consciousness without brain activity, then consciousness must dwell somewhere beyond the brain
  • Some of the parapsychologists speculate that it is a “non-local” force that pervades the universe, like electromagnetism. This force is received by the brain, but is not generated by it, the way a television receives a broadcast.
  • In order for this argument to hold, something else has to be true: near-death experiences have to happen during death, after the brain shuts down
  • To prove this, parapsychologists point to a number of rare but astounding cases known as “veridical” near-death experiences, in which patients seem to report details from the operating room that they might have known only if they had conscious awareness during the time that they were clinically dead.
  • At the very least, Parnia and his colleagues have written, such phenomena are “inexplicable through current neuroscientific models”. Unfortunately for the parapsychologists, however, none of the reports of post-death awareness holds up to strict scientific scrutiny. “There are many claims of this kind, but in my long decades of research into out-of-body and near-death experiences I never met any convincing evidence that this is true,”
  • In other cases, there’s not enough evidence to prove that the experiences reported by cardiac arrest survivors happened when their brains were shut down, as opposed to in the period before or after they supposedly “flatlined”. “So far, there is no sufficiently rigorous, convincing empirical evidence that people can observe their surroundings during a near-death experience,”
  • The parapsychologists tend to push back by arguing that even if each of the cases of veridical near-death experiences leaves room for scientific doubt, surely the accumulation of dozens of these reports must count for something. But that argument can be turned on its head: if there are so many genuine instances of consciousness surviving death, then why should it have so far proven impossible to catch one empirically?
  • The spiritualists and parapsychologists are right to insist that something deeply weird is happening to people when they die, but they are wrong to assume it is happening in the next life rather than this one. At least, that is the implication of what Jimo Borjigin found when she investigated the case of Patient One.
  • In the moments after Patient One was taken off oxygen, there was a surge of activity in her dying brain. Areas that had been nearly silent while she was on life support suddenly thrummed with high-frequency electrical signals called gamma waves. In particular, the parts of the brain that scientists consider a “hot zone” for consciousness became dramatically alive. In one section, the signals remained detectable for more than six minutes. In another, they were 11 to 12 times higher than they had been before Patient One’s ventilator was removed.
  • “As she died, Patient One’s brain was functioning in a kind of hyperdrive,” Borjigin told me. For about two minutes after her oxygen was cut off, there was an intense synchronisation of her brain waves, a state associated with many cognitive functions, including heightened attention and memory. The synchronisation dampened for about 18 seconds, then intensified again for more than four minutes. It faded for a minute, then came back for a third time.
  • n those same periods of dying, different parts of Patient One’s brain were suddenly in close communication with each other. The most intense connections started immediately after her oxygen stopped, and lasted for nearly four minutes. There was another burst of connectivity more than five minutes and 20 seconds after she was taken off life support. In particular, areas of her brain associated with processing conscious experience – areas that are active when we move through the waking world, and when we have vivid dreams – were communicating with those involved in memory formation. So were parts of the brain associated with empathy. Even as she slipped irre
  • something that looked astonishingly like life was taking place over several minutes in Patient One’s brain.
  • Although a few earlier instances of brain waves had been reported in dying human brains, nothing as detailed and complex as what occurred in Patient One had ever been detected.
  • Given the levels of activity and connectivity in particular regions of her dying brain, Borjigin believes it’s likely that Patient One had a profound near-death experience with many of its major features: out-of-body sensations, visions of light, feelings of joy or serenity, and moral re-evaluations of one’s life. Of course,
  • “The brain, contrary to everybody’s belief, is actually super active during cardiac arrest,” Borjigin said. Death may be far more alive than we ever thought possible.
  • “The brain is so resilient, the heart is so resilient, that it takes years of abuse to kill them,” she pointed out. “Why then, without oxygen, can a perfectly healthy person die within 30 minutes, irreversibly?”
  • Evidence is already emerging that even total brain death may someday be reversible. In 2019, scientists at Yale University harvested the brains of pigs that had been decapitated in a commercial slaughterhouse four hours earlier. Then they perfused the brains for six hours with a special cocktail of drugs and synthetic blood. Astoundingly, some of the cells in the brains began to show metabolic activity again, and some of the synapses even began firing.

Football and racist language: Reclaiming the Y-word | The Economist - 0 views

  • Game theory Sports Previous Next Latest Game theory Latest from all our blogs Football and racist language Reclaiming the Y-word Nov 9th 2012, 16:28 by B.R. ENGLISH football grounds in the 1980s were not pleasant places. Fans were squeezed into caged terraces which were often left open to the elements. Hooliganism was rife and the country was in a state of moral panic as lurid images of fighting youths became a fixture on news bulletins. Margaret Thatcher, the prime minister, convened a "war cabinet". Ken Bates, the chairman of Chelsea football club, suggested electrifying the fences in the stadiums to keep the warring factions apart. By the end of the decade English football reached its nadir. In 1985, 39 Italian football fans had been killed in Heysel, Belgium after a riot by Liverpool supporters. In 1989, Liverpool supporters themselves were the victims as 96 lost their lives at Hillsborough as a result of incompetent policing.Some time toward the beginning of that decade, aged around ten, your correspondent was taken to his first away game by his father, a fanatical supporter of Tottenham Hotspur. The game was a derby with Chelsea, a bitter London rival. Chelsea's fans were among the game’s most notorious. Many were skinheads; foot soldiers of extreme right-wing parties such as the National Front and the British Movement. Tottenham, because of the area in North London in which it is situated, had a large and visible Jewish following. It did not make for a pleasant combination. At one point during the first half the hostile Chelsea crowd fell suddenly silent. Quietly at first came a hissing sound, like someone letting out gas from a canister. Before long the hissing reached crescendo. It was a terrifying sound for a small boy. But I was too young to grasp the significance. Only later was I filled in: the Chelsea fans were mimicking the sound of cyanide being released at a Nazi concentration camp. As the years wore on, the abuse towards Spurs fans became less subtle. When clubs with a large right-wing following came to Tottenham’s White Hart Lane stadium, such as Chelsea, West Ham, Leeds and Manchester United, the anti-semitism was relentless. One common song ran:Spurs are on their way to BelsenHitler's going to gas ‘em againThe Yids from TottenhamThe Yids from White Hart Lane The Y-word. It was the most relentless chant of all. Thousand of opposition fans, faces snarled, would come together in spiteful mantra: “Yiddo! Yiddo!” It was directed towards Tottenham fans and players alike. It would go on for minutes at a time, many times in a game. After a while it was so commonplace that one became immune to it. At some point during that time, something odd began to happen. Tottenham fans began to appropriate the Y-word. Gradually they began to refer to themselves as Yids. The club’s supporters started to describe themselves as the “Yid Army”. Soon the word was being chanted solely by Tottenham fans referring to themselves in a spirit of celebration and of togetherness. It had been reclaimed in much the same way that the word “nigger” was taken back by black hip-hop artists and “queer” was by gays.As a result, the word died as an insult, at least within football grounds.

Holly the Cat's Incredible Journey - NYTimes.com - 0 views

  • “I really believe these stories, but they’re just hard to explain,” said Marc Bekoff, a behavioral ecologist at the University of Colorado. “Maybe being street-smart, maybe reading animal cues, maybe being able to read cars, maybe being a good hunter. I have no data for this.”There is, in fact, little scientific dogma on cat navigation. Migratory animals like birds, turtles and insects have been studied more closely, and use magnetic fields, olfactory cues, or orientation by the sun.
  • Strange, faraway locations would seem problematic, although he and Patrick Bateson, a behavioral biologist at Cambridge University, say that cats can sense smells across long distances. “Let’s say they associate the smell of pine with wind coming from the north, so they move in a southerly direction,”
  • Professor Tabor cited longer-distance reports he considered credible: Murka, a tortoiseshell in Russia, traveling about 325 miles home to Moscow from her owner’s mother’s house in Voronezh in 1989; Ninja, who returned to Farmington, Utah, in 1997, a year after her family moved from there to Mill Creek, Wash.; and Howie, an indoor Persian cat in Australia who in 1978 ran away from relatives his vacationing family left him with and eventually traveled 1,000 miles to his family’s home.

  • The closest, said Roger Tabor, a British cat biologist, may have been a 1954 study in Germany which cats placed in a covered circular maze with exits every 15 degrees most often exited in the direction of their homes, but more reliably if their homes were less than five kilometers away.
  • “We haven’t the slightest idea how they do this,” Mr. Galaxy said. “Anybody who says they do is lying, and, if you find it, please God, tell me what it is.”

Australia Banned Assault Weapons. America Can, Too. - NYTimes.com - 0 views

  • I can, however, describe what I, as prime minister of Australia, did to curb gun violence following a horrific massacre 17 years ago in the hope that it will contribute constructively to the debate in the United States.
  • Our challenges were different from America’s. Australia is an even more intensely urban society, with close to 60 percent of our people living in large cities. Our gun lobby isn’t as powerful or well-financed as the National Rifle Association in the United States. Australia, correctly in my view, does not have a Bill of Rights, so our legislatures have more say than America’s over many issues of individual rights, and our courts have less control. Also, we have no constitutional right to bear arms. (After all, the British granted us nationhood peacefully; the United States had to fight for it.)
  • To make this plan work, there had to be a federally financed gun buyback scheme. Ultimately, the cost of the buyback was met by a special one-off tax imposed on all Australians. This required new legislation and was widely accepted across the political spectrum. Almost 700,000 guns were bought back and destroyed — the equivalent of 40 million guns in the United States.

  • Given our decentralized system of government, I could reduce the number of dangerous firearms only by persuading the states to enact uniform laws totally prohibiting the ownership, possession and sale of all automatic and semiautomatic weapons while the national government banned the importation of such weapons.
  • The fundamental problem was the ready availability of high-powered weapons, which enabled people to convert their murderous impulses into mass killing.
  • I made clear that my government was willing to hold a nationwide referendum to alter the Australian Constitution and give the federal government constitutional power over guns. Such a referendum would have been expensive and divisive, but it would have passed. And all state governments knew this.
  • today, there is a wide consensus that our 1996 reforms not only reduced the gun-related homicide rate, but also the suicide rate. The Australian Institute of Criminology found that gun-related murders and suicides fell sharply after 1996. The American Journal of Law and Economics found that our gun buyback scheme cut firearm suicides by 74 percent. In the 18 years before the 1996 reforms, Australia suffered 13 gun massacres — each with more than four victims — causing a total of 102 deaths. There has not been a single massacre in that category since 1996. Few Australians would deny that their country is safer today as a consequence of gun control.

Relax, the Apocalypse Isn't on Friday-It's Just a 'Reset' - Eugen Tomiuc - The Atlantic - 0 views

  • To what extent is this reflecting people's need for balance between scientific fact and religious reassurance?
  • There is some sort of desire to make a synthesis of both spiritual ideas and also science. And you can trace that back to theosophy at the turn of the last century. So I think there is a synthesis here of both science and spirituality which in our age is something that people want. They want to somehow be able to cross that great divide -- what [British scientist and novelist] C.P. Snow called 'the two cultures' -- and try to find meaning in both worlds.

Mining Books To Map Emotions Through A Century : Shots - Health News : NPR - 1 views

  • Were people happier in the 1950s than they are today? Or were they more frustrated, repressed and sad? To find out, you'd have to compare the emotions of one generation to another. British anthropologists think they may have found the answer — embedded in literature.
  • This effort began simply with lists of "emotion" words: 146 different words that connote anger; 92 words for fear; 224 for joy; 115 for sadness; 30 for disgust; and 41 words for surprise. All were from standardized word lists used in linguistic research.
  • We didn't really expect to find anything," he says. "We were just curious. We really expected the use of emotion words to be constant through time." Instead, in the study they published in the journal PLOS ONE, the anthropologists found very distinct peaks and valleys, Bently says.
  • ...4 more annotations...
  • "The twenties were the highest peak of joy-related words that we see," he says. "They really were roaring." But then there came 1941, which, of course, marked the beginning of America's entry into World War II. It doesn't take a historian to see that peaks and valleys like these roughly mirror the major economic and social events of the century. "In 1941, sadness is at its peak," Bently says.
  • They weren't just novels or books about current events, Bentley says. Many were books without clear emotional content — technical manuals about plants and animals, for example, or automotive repair guides. "It's not like the change in emotion is because people are writing about the Depression, and people are writing about the war," he says. "There might be a little bit of that, but this is just, kind of, averaged over all books and it's just kind of creeping in."
  • Generally speaking the usage of these commonly known emotion words has been in decline over the 20th century," Bentley says. We used words that expressed our emotions less in the year 2000 than we did 100 years earlier — words about sadness, and joy, and anger, and disgust and surprise. In fact, there is only one exception that Bentley and his colleagues found: fear. "The fear-related words start to increase just before the 1980s," he says.
  • For psychologists, he says, there are only a handful of ways to try to understand what is actually going on with somebody emotionally. "One is what a person says," Pennebaker explains, "kind of the 'self report' of emotion. Another might be the physiological links, and the third is what slips out when they're talking to other people, when they're writing a book or something like that."
  •  
    Researchers have found a connection between economic troubles and the emotions used in various genres of literature over time. What I found most interesting was that, even in non-fiction, technical literature, the researchers still found differences in words used that had a certain emotional connotation, depending on the emotions of the time period. It seems that these anthropologists are finding a link between the way our culture and emotion influences our language.

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.
  • ...9 more annotations...
  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.

News Report on Global Temperatures Is Wrong, Scientists Say - 0 views

  •  
    Scientists on Friday debunked a widely circulated news media report suggesting that recent record-high global temperatures were unrelated to climate change. The report, which first appeared in the British tabloid The Daily Mail and was summarized in Breitbart News, the right-wing opinion and news site, cited incomplete data and drew incorrect conclusions, the scientists said.

Harrow: What do we believe when history books keep changing? | www.mystatesman.com - 0 views

  • The second world history was a $5 find at Half-Price Books, published in 1925 by sci-fi author H.G. Wells. The third, published in 1993 by British historian J. M. Roberts, snuck into my library unnoticed. How might these books treat the same subject?
  • Most striking is how authors differ. Swinton concludes, “Many Mohammedans inspired Christian knights with esteem and admiration.” Wells concludes in 1925 that Crusades “left a quite insane intolerance between Christendom and Islam” — an issue resonating 91 years later
  • By checking our sources’ agendas. I trust Consumer Reports because it has no ads. I trust PolitiFact about lying politicians because it’s vetted by newspapers nationwide. I trust Wikipedia because of transparent fact-checking.

This is what it's like to grow up in the age of likes, lols and longing | The Washingto... - 1 views

  • She slides into the car, and even before she buckles her seat belt, her phone is alight in her hands. A 13-year-old girl after a day of eighth grade.
  • She doesn’t respond, her thumb on Instagram. A Barbara Walters meme is on the screen. She scrolls, and another meme appears. Then another meme, and she closes the app. She opens BuzzFeed. There’s a story about Florida Gov. Rick Scott, which she scrolls past to get to a story about Janet Jackson, then “28 Things You’ll Understand If You’re Both British and American.” She closes it. She opens Instagram. She opens the NBA app. She shuts the screen off. She turns it back on. She opens Spotify. Opens Fitbit. She has 7,427 steps. Opens Instagram again. Opens Snapchat. She watches a sparkly rainbow flow from her friend’s mouth. She watches a YouTube star make pouty faces at the camera. She watches a tutorial on nail art. She feels the bump of the driveway and looks up. They’re home. Twelve minutes have passed.
  • Katherine Pommerening’s iPhone is the place where all of her friends are always hanging out. So it’s the place where she is, too.

  • “Over 100 likes is good, for me. And comments. You just comment to make a joke or tag someone.”
  • The best thing is the little notification box, which means someone liked, tagged or followed her on Instagram. She has 604 followers. There are only 25 photos on her page because she deletes most of what she posts. The ones that don’t get enough likes, don’t have good enough lighting or don’t show the coolest moments in her life must be deleted.
  • Sociologists, advertisers, stock market analysts – everyone wants to know what happens when the generation born glued to screens has to look up and interact with the world.
  • “It kind of, almost, promotes you as a good person. If someone says, ‘tbh you’re nice and pretty,’ that kind of, like, validates you in the comments. Then people can look at it and say ‘Oh, she’s nice and pretty.’ ”
  • School is where she thrives: She is beloved by her teachers, will soon star as young Simba in the eighth-grade performance of “The Lion King” musical, and gets straight A’s. Her school doesn’t offer a math course challenging enough for her, so she takes honors algebra online through Johns Hopkins University.
  • “Happy birthday posts are a pretty big deal,” she says. “It really shows who cares enough to put you on their page.”
  • He checks the phone bill to see who she’s called and how much she’s been texting, but she barely calls anyone and chats mostly through Snapchat, where her messages disappear.
  • Some of Katherine’s very best friends have never been to her house, or she to theirs. To Dave, it seems like they rarely hang out, but he knows that to her, it seems like they’re together all the time.
  • Dave Pommerening wants to figure out how to get her to use it less. One month, she ate up 18 gigabytes of data. Most large plans max out at 10. He intervened and capped her at four GB. “I don’t want to crimp it too much,” he says. “That’s something, from my perspective, I’m going to have to figure out, how to get my arms around that.”
  • Even if her dad tried snooping around her apps, the true dramas of teenage girl life are not written in the comments. Like how sometimes, Katherine’s friends will borrow her phone just to un-like all the Instagram photos of girls they don’t like. Katherine can’t go back to those girls’ pages and re-like the photos because that would be stalking, which is forbidden.
  • Or how last week, at the middle school dance, her friends got the phone numbers of 10 boys, but then they had to delete five of them because they were seventh-graders. And before she could add the boys on Snapchat, she realized she had to change her username because it was her childhood nickname and that was totally embarrassing.
  • Then, because she changed her username, her Snapchat score reverted to zero. The app awards about one point for every snap you send and receive. It’s also totally embarrassing and stressful to have a low Snapchat score. So in one day, she sent enough snaps to earn 1,000 points.
  • Snapchat is where flirting happens. She doesn’t know anyone who has sent a naked picture to a boy, but she knows it happens with older girls, who know they have met the right guy.
  • Nothing her dad could find on her phone shows that for as good as Katherine is at math, basketball and singing, she wants to get better at her phone. To be one of the girls who knows what to post, how to caption it, when to like, what to comment.
  • Katherine doesn’t need magazines or billboards to see computer-perfect women. They’re right on her phone, all the time, in between photos of her normal-looking friends. There’s Aisha, there’s Kendall Jenner’s butt. There’s Olivia, there’s YouTube star Jenna Marbles in lingerie.
  • The whole world is at her fingertips and has been for years. This, Katherine offers as a theory one day, is why she doesn’t feel like she’s 13 years old at all. She’s probably, like, 16.
  • “I don’t feel like a child anymore” she says. “I’m not doing anything childish. At the end of sixth grade” — when all her friends got phones and downloaded Snapchat, Instagram and Twitter — “I just stopped doing everything I normally did. Playing games at recess, playing with toys, all of it, done.”
  • Her scooter sat in the garage, covered in dust. Her stuffed animals were passed down to Lila. The wooden playground in the back yard stood empty. She kept her skateboard with neon yellow wheels, because riding it is still cool to her friends.
  • On the morning of her 14th birthday, Katherine wakes up to an alarm ringing on her phone. It’s 6:30 a.m. She rolls over and shuts it off in the dark. Her grandparents, here to celebrate the end of her first year of teenagehood, are sleeping in the guest room down the hall. She can hear the dogs shuffling across the hardwood downstairs, waiting to be fed. Propping herself up on her peace-sign-covered pillow, she opens Instagram. Later, Lila will give her a Starbucks gift card. Her dad will bring doughnuts to her class. Her grandparents will take her to the Melting Pot for dinner. But first, her friends will decide whether to post pictures of Katherine for her birthday. Whether they like her enough to put a picture of her on their page. Those pictures, if they come, will get likes and maybe tbhs. They should be posted in the morning, any minute now. She scrolls past a friend posing in a bikini on the beach. Then a picture posted by Kendall Jenner. A selfie with coffee. A basketball Vine. A selfie with a girl’s tongue out. She scrolls, she waits. For that little notification box to appear.

Do Your Friends Actually Like You? - The New York Times - 1 views

  • Recent research indicates that only about half of perceived friendships are mutual. That is, someone you think is your friend might not be so keen on you. Or, vice versa, as when someone you feel you hardly know claims you as a bestie.
  • “The notion of doing nothing but spending time in each other’s company has, in a way, become a lost art,” replaced by volleys of texts and tweets, Mr. Sharp said. “People are so eager to maximize efficiency of relationships that they have lost touch with what it is to be a friend.”
  • It’s a concern because the authenticity of one’s relationships has an enormous impact on one’s health and well-being.
  • ...11 more annotations...
  • The study analyzed friendship ties among 84 subjects (ages 23 to 38) in a business management class by asking them to rank one another on a five-point continuum of closeness from “I don’t know this person” to “One of my best friends.” The feelings were mutual 53 percent of the time while the expectation of reciprocity was pegged at 94 percent. This is consistent with data from several other friendship studies conducted over the past decade, encompassing more than 92,000 subjects, in which the reciprocity rates ranged from 34 percent to 53 percent.
  • “Friendship is difficult to describe,” said Alexander Nehamas, a professor of philosophy at Princeton, who in his latest book, “On Friendship,” spends almost 300 pages trying to do just that. “It’s easier to say what friendship is not and, foremost, it is not instrumental.”
  • It is not a means to obtain higher status, wangle an invitation to someone’s vacation home or simply escape your own boredom. Rather, Mr. Nehamas said, friendship is more like beauty or art, which kindles something deep within us and is “appreciated for its own sake.
  • “Treating friends like investments or commodities is anathema to the whole idea of friendship,” said Ronald Sharp, a professor of English at Vassar College, who teaches a course on the literature of friendship. “It’s not about what someone can do for you, it’s who and what the two of you become in each other’s presence.”
  • Some blame human beings’ basic optimism, if not egocentrism, for the disconnect between perceived and actual friendships. Others point to a misunderstanding of the very notion of friendship in an age when “friend” is used as a verb, and social inclusion and exclusion are as easy as a swipe or a tap on a smartphone screen.
  • By his definition, friends are people you take the time to understand and allow to understand you.
  • Because time is limited, so, too, is the number of friends you can have, according to the work of the British evolutionary psychologist Robin I.M. Dunbar. He describes layers of friendship, where the topmost layer consists of only one or two people, say a spouse and best friend with whom you are most intimate and interact daily. The next layer can accommodate at most four people for whom you have great affinity, affection and concern and who require weekly attention to maintain. Out from there, the tiers contain more casual friends with whom you invest less time and tend to have a less profound and more tenuous connection. Without consistent contact, they easily fall into the realm of acquaintance. You may be friendly with them but they aren’t friends.
  • “There is a limited amount of time and emotional capital we can distribute, so we only have five slots for the most intense type of relationship,” Mr. Dunbar said. “People may say they have more than five but you can be pretty sure they are not high-quality friendships.
  • Such boasting implies they have soul mates to spare in a culture where we are taught that leaning on someone is a sign of weakness and power is not letting others affect you. But friendship requires the vulnerability of caring as well as revealing things about yourself that don’t match the polished image in your Facebook profile or Instagram feed, said Mr. Nehamas at Princeton. Trusting that your bond will continue, and might even be strengthened, despite your shortcomings and inevitable misfortunes, he said, is a risk many aren’t willing to take.
  • According to medical experts, playing it safe by engaging in shallow, unfulfilling or nonreciprocal relationships has physical repercussions. Not only do the resulting feelings of loneliness and isolation increase the risk of death as much as smoking, alcoholism and obesity; you may also lose tone, or function, in the so-called smart vagus nerve, which brain researchers think allows us to be in intimate, supportive and reciprocal relationships in the first place.
  • In the presence of a true friend, Dr. Banks said, the smart or modulating aspect of the vagus nerve is what makes us feel at ease rather than on guard as when we are with a stranger or someone judgmental. It’s what enables us to feel O.K. about exposing the soft underbelly of our psyche and helps us stay engaged and present in times of conflict. Lacking authentic friendships, the smart vagus nerve is not exercised. It loses tone and one’s anxiety remains high, making abiding, deep connections difficult.

The Anger Wave That May Just Wipe Out Laissez-Faire Economics - The New York Times - 1 views

  • few would have guessed that the economic order built upon Mr. Reagan’s and Mrs. Thatcher’s common faith in unfettered global markets (and largely accepted by their more liberal successors Bill Clinton and Tony Blair) would be brought down by right-wing populists riding the anger of a working class that has been cast aside in the globalized economy that the two leaders trumpeted 40 years ago.
  • The so-called Brexit vote was driven by an inchoate sense among older white workers with modest education that they have been passed over, condemned by forces beyond their control to an uncertain job for little pay in a world where their livelihoods are challenged not just by cheap Asian workers halfway around the world, but closer to home by waves of immigrants of different faiths and skin tones.
  • It is the same frustration that has buoyed proto-fascist political parties across Europe. It is the same anger fueling the candidacy of Mr. Trump in the United States.
  • ...7 more annotations...
  • Mr. Trump, the bombastic businessman who’s never held office, and Mr. Johnson, the former journalist turned mayor of London, might not put it this way, since they continue to cling to a conservative mantle. But they are riding a revolt of the working class against a 40-year-long project of the political right and its corporate backers that has dominated policy making in the English-speaking world for a generation.
  • The British political scientist Andrew Gamble at the University of Cambridge has argued that Western capitalism has experienced two transformational crises since the end of the 19th century. The first, brought about by the Depression of the 1930s, ended an era in which governments bowed to the gospel of the gold standard and were expected to butt out of the battles between labor and capital, letting markets function on their own, whatever the consequences
  • Mr. Keynes’s views ultimately prevailed, though, providing the basis for a new post-World War II orthodoxy favoring active government intervention in the economy and a robust welfare state. But that era ended when skyrocketing oil prices and economic mismanagement in the 1970s brought about a combination of inflation and unemployment that fatally undermined people’s trust in the state.
  • The Keynesian era ended when Margaret Thatcher and Ronald Reagan rode onto the scene with a version of capitalism based on tax cuts, privatization and deregulation that helped revive their engines of growth but led the workers of the world to the deeply frustrating, increasingly unequal economy of today.
  • After the Brexit vote, Lawrence Summers, former Treasury secretary under President Clinton and one of President Obama’s top economic advisers at the nadir of the Great Recession, laid out an argument for what he called “responsible nationalism,” which focused squarely on the interests of domestic workers.
  • Instead of negotiating more agreements to ease business across borders, governments would focus on deals to improve labor and environmental standards internationally. They might cut deals to prevent cross-border tax evasion.
  • There is, however, little evidence that the world’s leaders will go down that path. Despite the case for economic stimulus, austerity still rules across much of the West. In Europe, most governments have imposed stringent budget cuts — ensuring that all but the strongest economies would stall. In the United States, political polarization has brought fiscal policy — spending and taxes — to a standstill.

The Science of Making Friends - WSJ - 0 views

  • people with solid friendships live healthier, longer lives. Friendship decreases blood pressure and stress, reduces the risk of depression and increases longevity, in large part because someone is watching out for us.
  • A study published in February in the British Journal of Psychology looked at 15,000 respondents and found that people who had more social interactions with close friends reported being happier—unless they were highly intelligent.
  • People with higher I.Q.s were less content when they spent more time with friends. Psychologists theorize that these folks keep themselves intellectually stimulated without a lot of social interaction, and often have a long-term goal they are pursuing.

School also provides a steady routine for people to develop intimacy slowly and naturally.

A Better Way to Teach Math - NYTimes.com - 2 views

  • “Almost every kid — and I mean virtually every kid — can learn math at a very high level, to the point where they could do university level math courses,”
  • “If you ask why that’s not happening, it’s because very early in school many kids get the idea that they’re not in the smart group, especially in math. We kind of force a choice on them: to decide that either they’re dumb or math is dumb.”
  • In particular, math teachers often fail to make sufficient allowances for the limitations of working memory and the fact that we all need extensive practice to gain mastery in just about anything.

  • current teaching approaches underestimate the amount of explicit guidance, “scaffolding” and practice children need to consolidate new concepts. Asking children to make their own discoveries before they solidify the basics is like asking them to compose songs on guitar before they can form a C chord.
  • he gained a reputation as a kind of math miracle worker. Many students were sent to him because they had severe learning disabilities (a number have gone on to do university-level math). Mighton found that to be effective he often had to break things down into minute steps and assess each student’s understanding at each micro-level before moving on.
  • Mighton saw that if he approached teaching this way, he could virtually guarantee that every student would experience success. In turn, the children’s math anxiety diminished. As they grew more confident, they grew excited, and they began requesting harder challenges. “More than anything, kids love success,” he says, “and they love getting to higher levels, like in a video game.”
  • Mighton saw that if you provided painstaking guidance, children would make their own discoveries. That’s why he calls his approach “guided discovery.”
  • Schools in British Columbia evaluate students based on whether they meet expectations for learning outcomes. “Teachers who used Jump were suddenly finding that they had all of their kids in the ‘fully meeting expectations’ category,” Grant told me. “It was such a foreign experience. It doesn’t typically happen when we’re teaching science or language arts. And they were kind of at a loss. ‘What do we do about this?’”
  • Even deeper, for children, math looms large; there’s something about doing well in math that makes kids feel they are smart in everything. In that sense, math can be a powerful tool to promote social justice. “When you have all the kids in a class succeeding in a subject, you see that they’re competing against the problem, not one another,” says Mighton. “It’s like they’re climbing a mountain together. You see a very healthy kind of competition. And it makes kids more generous to one another. Math can save us.”

Breitbart's James Delingpole says reef bleaching is 'fake news', hits peak denial | Gra... - 0 views

  • It takes a very special person to label the photographed, documented, filmed and studied phenomenon of mass coral bleaching on the Great Barrier Reef “fake news”.
  • It also helps if you can hide inside the bubble of the hyper-partisan Breitbart media outlet, whose former boss is the US president’s chief strategist.
  • So our special person is the British journalist James Delingpole who, when he’s not denying the impacts of coral bleaching, is denying the science of human-caused climate change, which he says is “the biggest scam in the history of the world”.

  • When we talk about the reef dying, what we are talking about are the corals that form the reef’s structure – the things that when in a good state of health can be splendorous enough to support about 69,000 jobs in Queensland and add about $6bn to Australia’s economy every year.
  • The Great Barrier Reef has suffered mass coral bleaching three times – in 1998, 2002 and 2016 – with a fourth episode now unfolding. The cause is increasing ocean temperatures.
  • So it seems we are now at a stage where absolutely nothing is real unless you have seen it for yourself,
  • Senator Pauline Hanson and her One Nation climate science-denying colleagues tried to pull a similar stunt last year by taking a dive on a part of the reef that had escaped bleaching and then claiming this as proof that everything was OK everywhere else.
  • Corals bleach when they are exposed to abnormally high ocean temperatures for too long. Under stress, the corals expel the algae that give them their colour and more of their nutrients.
  • After the 2016 bleaching, a quarter of all corals on the reef, mostly located in the once “pristine” northern section, died before there was a chance for recovery.
  • Essentially, the study found the only measure that would give corals on the reef a fighting chance was to rapidly reduce greenhouse gas emissions.
  • Some commentators have suggested a key cause of the 2016 bleaching was the El Niño weather pattern that tends to deliver warmer global temperatures. But Hughes says that before 1998, the Great Barrier Reef went through countless El Niños without suffering the extensive mass bleaching episodes that are being seen, photographed, filmed and documented now.
  •  
    This frustrates me enormously. When there is evidence of bleaching of the coral and the impact of global warming on this coral, I don't understand how people can say this is fake news. It seems the US, at least, will not be helping fix this problem, but the whole world is at fault for this, and we should be a part of fixing it.

Sullivan: Is Political Gravity Finally Sinking Donald Trump? - 0 views

  • Compare this with, say, the reaction to the Boston marathon bombing. An entire city was brought to a standstill and locked down, while the pursuit of a deranged, unarmed teenager continued.

If we want the Constitution to survive both Islamism’s threat and the potential response of a beleaguered Trump, we’ll have to.

The Trouble With Neutrinos That Outpaced Einstein's Theory - NYTimes.com - 0 views

  • The British astrophysicist Arthur S. Eddington once wrote, “No experiment should be believed until it has been confirmed by theory.”
  • Adding to the sense of finality was the simple fact — as Eddington might have pointed out — that faster-than-light neutrinos had never been confirmed by theory. Or as John G. Learned, a neutrino physicist at the University of Hawaii, put it in an e-mail, “An interesting result of all this fracas is that no new model I have seen (or heard of from my friends) really is credible to explain the faster-than-light neutrinos.”
  • Eddington’s dictum is not as radical as it might sound. He made it after early measurements of the rate of expansion of the universe made it appear that our planet was older than the cosmos in which it resides — an untenable notion. “It means that science is not just a book of facts, it is understanding as well,”
