How Life Began: New Clues | TIME.com - 0 views

  • Astronomers recently announced that there could be an astonishing 20 billion Earthlike planets in the Milky Way
  • How abundant life actually is, however, hinges on one crucial factor: given the right conditions and the right raw materials,
  • what is the mathematical likelihood that life will actually would arise?

  • biology would have to be popping up all over the place.
  • Andrew Ellington, of the Center for Systems and Synthetic Biology at the University of Texas, Austin, “I can’t tell you what the probability is. It’s a chapter of the story that’s pretty much blank.”
  • Given that rather bleak-sounding assessment, it may be surprising to learn that Ellington is actually pretty upbeat. But that’s how he and two colleagues come across in a paper in the latest Science. The crucial step from nonliving stuff to a live cell is still a mystery, they acknowledge, but the number of pathways a mix of inanimate chemicals could have taken to reach the threshold of the living turns out to be many and varied. “It’s difficult to say exactly how things did occur,” says Ellington. “But there are many ways it could have occurred.
  • The first stab at answering the question came all the way back in the 1950s, when chemists Stanley Miller and Harold Urey passed an electrical spark through a beaker containing methane, ammonia, water vapor and hydrogen, thought at the time to represent Earth’s primordial atmosphere.
  • Scientists have learned so much, in fact, that the number of places life might have begun has grown to include such disparate locations as the hydrothermal vents at the bottom of the ocean; beds of clay; the billowing clouds of gas emerging from volcanoes; and the spaces in between ice crystals.
  • The number of ideas about how the key step from organic chemicals to living organisms might have been taken has multiplied as well: there’s the “RNA world hypothesis” and the “lipid world hypothesis” and the “iron-sulfur world hypothesis” and more, all of them dependent on a particular set of chemical circumstances and a particular set of dynamics and all highly speculative.
  • “Maybe when they do,” says Ellington, “we’ll all do a face-plant because it turns out to be so obvious in retrospect.” But even if they succeed, it will only prove that a manufactured cell could represent the earliest life forms, not that it actually does. “It will be a story about what we think might have happened, but it will still be a story.”
  • The story Ellington and his colleagues have been able to tell already, however, is a reason for optimism. We still don’t know the odds that life will arise under the right conditions. But the underlying biochemistry is abundantly, ubiquitously available—and it would take an awfully perverse universe to take things so far only to shut them down at the last moment.

George Packer: Is Amazon Bad for Books? : The New Yorker - 0 views

  • Amazon is a global superstore, like Walmart. It’s also a hardware manufacturer, like Apple, and a utility, like Con Edison, and a video distributor, like Netflix, and a book publisher, like Random House, and a production studio, like Paramount, and a literary magazine, like The Paris Review, and a grocery deliverer, like FreshDirect, and someday it might be a package service, like U.P.S. Its founder and chief executive, Jeff Bezos, also owns a major newspaper, the Washington Post. All these streams and tributaries make Amazon something radically new in the history of American business
  • Amazon is not just the “Everything Store,” to quote the title of Brad Stone’s rich chronicle of Bezos and his company; it’s more like the Everything. What remains constant is ambition, and the search for new things to be ambitious about.
  • It wasn’t a love of books that led him to start an online bookstore. “It was totally based on the property of books as a product,” Shel Kaphan, Bezos’s former deputy, says. Books are easy to ship and hard to break, and there was a major distribution warehouse in Oregon. Crucially, there are far too many books, in and out of print, to sell even a fraction of them at a physical store. The vast selection made possible by the Internet gave Amazon its initial advantage, and a wedge into selling everything else.

  • it’s impossible to know for sure, but, according to one publisher’s estimate, book sales in the U.S. now make up no more than seven per cent of the company’s roughly seventy-five billion dollars in annual revenue.
  • A monopoly is dangerous because it concentrates so much economic power, but in the book business the prospect of a single owner of both the means of production and the modes of distribution is especially worrisome: it would give Amazon more control over the exchange of ideas than any company in U.S. history.
  • “The key to understanding Amazon is the hiring process,” one former employee said. “You’re not hired to do a particular job—you’re hired to be an Amazonian. Lots of managers had to take the Myers-Briggs personality tests. Eighty per cent of them came in two or three similar categories, and Bezos is the same: introverted, detail-oriented, engineer-type personality. Not musicians, designers, salesmen. The vast majority fall within the same personality type—people who graduate at the top of their class at M.I.T. and have no idea what to say to a woman in a bar.”
  • According to Marcus, Amazon executives considered publishing people “antediluvian losers with rotary phones and inventory systems designed in 1968 and warehouses full of crap.” Publishers kept no data on customers, making their bets on books a matter of instinct rather than metrics. They were full of inefficiences, starting with overpriced Manhattan offices.
  • For a smaller house, Amazon’s total discount can go as high as sixty per cent, which cuts deeply into already slim profit margins. Because Amazon manages its inventory so well, it often buys books from small publishers with the understanding that it can’t return them, for an even deeper discount
  • According to one insider, around 2008—when the company was selling far more than books, and was making twenty billion dollars a year in revenue, more than the combined sales of all other American bookstores—Amazon began thinking of content as central to its business. Authors started to be considered among the company’s most important customers. By then, Amazon had lost much of the market in selling music and videos to Apple and Netflix, and its relations with publishers were deteriorating
  • In its drive for profitability, Amazon did not raise retail prices; it simply squeezed its suppliers harder, much as Walmart had done with manufacturers. Amazon demanded ever-larger co-op fees and better shipping terms; publishers knew that they would stop being favored by the site’s recommendation algorithms if they didn’t comply. Eventually, they all did.
  • Brad Stone describes one campaign to pressure the most vulnerable publishers for better terms: internally, it was known as the Gazelle Project, after Bezos suggested “that Amazon should approach these small publishers the way a cheetah would pursue a sickly gazelle.”
  • ithout dropping co-op fees entirely, Amazon simplified its system: publishers were asked to hand over a percentage of their previous year’s sales on the site, as “marketing development funds.”
  • The figure keeps rising, though less for the giant pachyderms than for the sickly gazelles. According to the marketing executive, the larger houses, which used to pay two or three per cent of their net sales through Amazon, now relinquish five to seven per cent of gross sales, pushing Amazon’s percentage discount on books into the mid-fifties. Random House currently gives Amazon an effective discount of around fifty-three per cent.
  • In December, 1999, at the height of the dot-com mania, Time named Bezos its Person of the Year. “Amazon isn’t about technology or even commerce,” the breathless cover article announced. “Amazon is, like every other site on the Web, a content play.” Yet this was the moment, Marcus said, when “content” people were “on the way out.”
  • By 2010, Amazon controlled ninety per cent of the market in digital books—a dominance that almost no company, in any industry, could claim. Its prohibitively low prices warded off competition
  • In 2004, he set up a lab in Silicon Valley that would build Amazon’s first piece of consumer hardware: a device for reading digital books. According to Stone’s book, Bezos told the executive running the project, “Proceed as if your goal is to put everyone selling physical books out of a job.”
  • Lately, digital titles have levelled off at about thirty per cent of book sales.
  • The literary agent Andrew Wylie (whose firm represents me) says, “What Bezos wants is to drag the retail price down as low as he can get it—a dollar-ninety-nine, even ninety-nine cents. That’s the Apple play—‘What we want is traffic through our device, and we’ll do anything to get there.’ ” If customers grew used to paying just a few dollars for an e-book, how long before publishers would have to slash the cover price of all their titles?
  • As Apple and the publishers see it, the ruling ignored the context of the case: when the key events occurred, Amazon effectively had a monopoly in digital books and was selling them so cheaply that it resembled predatory pricing—a barrier to entry for potential competitors. Since then, Amazon’s share of the e-book market has dropped, levelling off at about sixty-five per cent, with the rest going largely to Apple and to Barnes & Noble, which sells the Nook e-reader. In other words, before the feds stepped in, the agency model introduced competition to the market
  • But the court’s decision reflected a trend in legal thinking among liberals and conservatives alike, going back to the seventies, that looks at antitrust cases from the perspective of consumers, not producers: what matters is lowering prices, even if that goal comes at the expense of competition. Barry Lynn, a market-policy expert at the New America Foundation, said, “It’s one of the main factors that’s led to massive consolidation.”
  • Publishers sometimes pass on this cost to authors, by redefining royalties as a percentage of the publisher’s receipts, not of the book’s list price. Recently, publishers say, Amazon began demanding an additional payment, amounting to approximately one per cent of net sales
  • brick-and-mortar retailers employ forty-seven people for every ten million dollars in revenue earned; Amazon employs fourteen.
  • Since the arrival of the Kindle, the tension between Amazon and the publishers has become an open battle. The conflict reflects not only business antagonism amid technological change but a division between the two coasts, with different cultural styles and a philosophical disagreement about what techies call “disruption.”
  • Bezos told Charlie Rose, “Amazon is not happening to bookselling. The future is happening to bookselling.”
  • n Grandinetti’s view, the Kindle “has helped the book business make a more orderly transition to a mixed print and digital world than perhaps any other medium.” Compared with people who work in music, movies, and newspapers, he said, authors are well positioned to thrive. The old print world of scarcity—with a limited number of publishers and editors selecting which manuscripts to publish, and a limited number of bookstores selecting which titles to carry—is yielding to a world of digital abundance. Grandinetti told me that, in these new circumstances, a publisher’s job “is to build a megaphone.”
  • it offers an extremely popular self-publishing platform. Authors become Amazon partners, earning up to seventy per cent in royalties, as opposed to the fifteen per cent that authors typically make on hardcovers. Bezos touts the biggest successes, such as Theresa Ragan, whose self-published thrillers and romances have been downloaded hundreds of thousands of times. But one survey found that half of all self-published authors make less than five hundred dollars a year.
  • The business term for all this clear-cutting is “disintermediation”: the elimination of the “gatekeepers,” as Bezos calls the professionals who get in the customer’s way. There’s a populist inflection to Amazon’s propaganda, an argument against élitist institutions and for “the democratization of the means of production”—a common line of thought in the West Coast tech world
  • “Book publishing is a very human business, and Amazon is driven by algorithms and scale,” Sargent told me. When a house gets behind a new book, “well over two hundred people are pushing your book all over the place, handing it to people, talking about it. A mass of humans, all in one place, generating tremendous energy—that’s the magic potion of publishing. . . . That’s pretty hard to replicate in Amazon’s publishing world, where they have hundreds of thousands of titles.”
  • By producing its own original work, Amazon can sell more devices and sign up more Prime members—a major source of revenue. While the company was building the
  • Like the publishing venture, Amazon Studios set out to make the old “gatekeepers”—in this case, Hollywood agents and executives—obsolete. “We let the data drive what to put in front of customers,” Carr told the Wall Street Journal. “We don’t have tastemakers deciding what our customers should read, listen to, and watch.”
  • book publishers have been consolidating for several decades, under the ownership of media conglomerates like News Corporation, which squeeze them for profits, or holding companies such as Rivergroup, which strip them to service debt. The effect of all this corporatization, as with the replacement of independent booksellers by superstores, has been to privilege the blockbuster.
  • The combination of ceaseless innovation and low-wage drudgery makes Amazon the epitome of a successful New Economy company. It’s hiring as fast as it can—nearly thirty thousand employees last year.
  • the long-term outlook is discouraging. This is partly because Americans don’t read as many books as they used to—they are too busy doing other things with their devices—but also because of the relentless downward pressure on prices that Amazon enforces.
  • he digital market is awash with millions of barely edited titles, most of it dreck, while r
  • Amazon believes that its approach encourages ever more people to tell their stories to ever more people, and turns writers into entrepreneurs; the price per unit might be cheap, but the higher number of units sold, and the accompanying royalties, will make authors wealthier
  • In Friedman’s view, selling digital books at low prices will democratize reading: “What do you want as an author—to sell books to as few people as possible for as much as possible, or for as little as possible to as many readers as possible?”
  • The real talent, the people who are writers because they happen to be really good at writing—they aren’t going to be able to afford to do it.”
  • Seven-figure bidding wars still break out over potential blockbusters, even though these battles often turn out to be follies. The quest for publishing profits in an economy of scarcity drives the money toward a few big books. So does the gradual disappearance of book reviewers and knowledgeable booksellers, whose enthusiasm might have rescued a book from drowning in obscurity. When consumers are overwhelmed with choices, some experts argue, they all tend to buy the same well-known thing.
  • These trends point toward what the literary agent called “the rich getting richer, the poor getting poorer.” A few brand names at the top, a mass of unwashed titles down below, the middle hollowed out: the book business in the age of Amazon mirrors the widening inequality of the broader economy.
  • “If they did, in my opinion they would save the industry. They’d lose thirty per cent of their sales, but they would have an additional thirty per cent for every copy they sold, because they’d be selling directly to consumers. The industry thinks of itself as Procter & Gamble*. What gave publishers the idea that this was some big goddam business? It’s not—it’s a tiny little business, selling to a bunch of odd people who read.”
  • Bezos is right: gatekeepers are inherently élitist, and some of them have been weakened, in no small part, because of their complacency and short-term thinking. But gatekeepers are also barriers against the complete commercialization of ideas, allowing new talent the time to develop and learn to tell difficult truths. When the last gatekeeper but one is gone, will Amazon care whether a book is any good? ♦

Hunting boosts lizard numbers in Australian desert | Science News - 0 views

Grayson Perry's Reith Lectures: Who decides what makes art good? - FT.com - 0 views

  • I think this is one of the most burning issues around art – how do we tell if something is good? And who tells us that it’s good?
  • many of the methods of judging are very problematic and many of the criteria used to assess art are conflicting. We have financial value, popularity, art historical significance, or aesthetic sophistication. All these things could be at odds with each other.
  • A visitor to an exhibition like the Hockney one, if they were judging the quality of the art, might use a word like “beauty”. Now, if you use that kind of word in the art world, be very careful. There will be sucking of teeth and mournful shaking of heads because their hero, the artist Marcel Duchamp, of “urinal” fame, he said, “Aesthetic delectation is the danger to be avoided.” In the art world sometimes it can feel as if to judge something on its beauty, on its aesthetic merits, is as if you’re buying into something politically incorrect, into sexism, into racism, colonialism, class privilege. It almost feels it’s loaded, because where does our idea of beauty come from?
  • ...16 more annotations...
  • beauty is very much about familiarity and it’s reinforcing an idea we have already. It’s like when we go on holiday, all we really want to do is take the photograph that we’ve seen in the brochure. Because our idea of beauty is constructed, by family, friends, education, nationality, race, religion, politics, all these things
  • I have found the 21st-century version of the Venetian secret and it is a mathematical formula. What you do, you get a half-decent, non-offensive kind of idea, then you times it by the number of studio assistants, and then you divide it with an ambitious art dealer, and that equals number of oligarchs and hedge fund managers in the world.
  • the nearest we have to an empirical measure of art that actually does exist is the market. By that reckoning, Cézanne’s “Card Players” is the most beautiful lovely painting in the world. I find it a little bit clunky-kitsch but that’s me. It’s worth $260m.
  • The opposite arguments are that it’s art for art’s sake and that’s a very idealistic position to take. Clement Greenberg, a famous art critic in the 1950s, said that art will always be tied to money by an umbilical cord of gold, either state money or market money. I’m pragmatic about it: one of my favourite quotes is you’ll never have a good art career unless your work fits into the elevator of a New York apartment block.
  • there’s one thing about that red painting that ends up in Sotheby’s. It’s not just any old red painting. It is a painting that has been validated. This is an important word in the art world and the big question is: who validates? There is quite a cast of characters in this validation chorus that will kind of decide what is good art. They are a kind of panel, if you like, that decides on what is good quality, what are we going to end up looking at?
  • They include artists, teachers, dealers, collectors, critics, curators, the media, even the public maybe. And they form this lovely consensus around what is good art.
  • there were four stages to the rise of an artist. Peers, serious critics and collectors, dealers, then the public.
  • Another member of that cast of validating characters is the collectors. In the 1990s, if Charles Saatchi just put his foot over the threshold of your exhibition, that was it. The media was agog and he would come in and Hoover it up. You do want the heavyweight collector to buy your work because that gives it kudos. You don’t want a tacky one who is just buying it to glitz up their hallway.
  • The next part of this chorus of validation are the dealers. A good dealer brand has a very powerful effect on the reputation of the artist; they form a part of placing the work. This is a slightly mysterious process that many people don’t quite understand but a dealer will choose where your work goes so it gains the brownie points, so the buzz around it goes up.
  • now, of course, galleries like the Tate Modern want a big name because visitor numbers, in a way, are another empirical measure of quality. So perhaps at the top of the tree of the validation cast are the curators, and in the past century they have probably become the most powerful giver-outers of brownie points in the art world.
  • ach of the encounters with these members of the cast of validation bestows upon the work, and on the artist, a patina, and what makes that patina is all these hundreds of little conversations and reviews and the good prices over time. These are the filters that pass a work of art through into the canon.
  • So what does this lovely consensus, that all these people are bestowing on this artwork, that anoints it with the quality that we all want, boil down to? I think in many ways what it boils down to is seriousness. That’s the most valued currency in the art world.
  • The whole idea of quality now seems to be contested, as if you’re buying into the language of the elite by saying, “Oh, that’s very good.” How you might judge this work is really problematic because to say it’s not beautiful is to put the wrong kind of criteria on it. You might say, “Oh, it’s dull!” [And people will say] “Oh, you’re just not understanding it with the right terms.” So I think, “Well, how do we judge these things?” Because a lot of them are quite politicised. There’s quite a right-on element to them, so do we judge them on how ethical they are, or how politically right-on they are?
  • What I am attempting to explain is how the art we see in museums and in galleries around the world, and in biennales – how it ends up there, how it gets chosen. In the end, if enough of the right people think it’s good, that’s all there is to it. But, as Alan Bennett said when he was a trustee of the National Gallery, they should put a big sign up outside saying: “You don’t have to like it all.”
  • Or then again I might say, “Well, what do I judge them against?” Do I judge them against government policy? Do I judge them against reality TV? Because that does participation very well. So, in the end, what do we do? What happens to this sort of art when it doesn’t have validation? What is it left with? It’s left with popularity.
  • Then, of course, the next group of people we might think about in deciding what is good art is the public. Since the mid-1990s, art has got a lot more media attention. But popularity has always been a quite dodgy quality [to have]. The highbrow critics will say, “Oh, he’s a bit of a celebrity,” and they turn their noses up about people who are well known to the public

BBC News - Exoplanet tally soars above 1,000 - 0 views

  • The number of observed exoplanets - worlds circling distant stars - has passed 1,000.
  • These new worlds are listed in the Extrasolar Planets Encyclopaedia.
  • The Kepler space telescope, which spotted many of these worlds in recent years, broke down earlier this year. Scientists still have to trawl through more than 3,500 other candidates from this mission so the number could rapidly increase.

  • The number of confirmed planets frequently increases because as scientists analyse the data they are able publish their results online immediately. But as the finds are not yet peer reviewed, the total figure remains subject to change.

Rise in Scientific Journal Retractions Prompts Calls for Reform - NYTimes.com - 1 views

  • before long they reached a troubling conclusion: not only that retractions were rising at an alarming rate, but that retractions were just a manifestation of a much more profound problem — “a symptom of a dysfunctional scientific climate,” as Dr. Fang put it.
  • he feared that science had turned into a winner-take-all game with perverse incentives that lead scientists to cut corners and, in some cases, commit acts of misconduct.
  • Members of the committee agreed with their assessment. “I think this is really coming to a head,” said Dr. Roberta B. Ness, dean of the University of Texas School of Public Health. And Dr. David Korn of Harvard Medical School agreed that “there are problems all through the system.”
  • ...20 more annotations...
  • science has changed in some worrying ways in recent decades — especially biomedical research, which consumes a larger and larger share of government science spending.
  • the journal Nature reported that published retractions had increased tenfold over the past decade, while the number of published papers had increased by just 44 percent.
  • because journals are now online, bad papers are simply reaching a wider audience, making it more likely that errors will be spotted.
  • The National Institutes of Health accepts a much lower percentage of grant applications today than in earlier decades. At the same time, many universities expect scientists to draw an increasing part of their salaries from grants, and these pressures have influenced how scientists are promoted.
  • Dr. Fang and Dr. Casadevall looked at the rate of retractions in 17 journals from 2001 to 2010 and compared it with the journals’ “impact factor,” a score based on how often their papers are cited by scientists. The higher a journal’s impact factor, the two editors found, the higher its retraction rate.
  • Each year, every laboratory produces a new crop of Ph.D.’s, who must compete for a small number of jobs, and the competition is getting fiercer. In 1973, more than half of biologists had a tenure-track job within six years of getting a Ph.D. By 2006 the figure was down to 15 percent.
  • Yet labs continue to have an incentive to take on lots of graduate students to produce more research. “I refer to it as a pyramid scheme,

  • “What people do is they count papers, and they look at the prestige of the journal in which the research is published, and they see how may grant dollars scientists have, and if they don’t have funding, they don’t get promoted,” Dr. Fang said. “It’s not about the quality of the research.”
  • Dr. Ness likens scientists today to small-business owners, rather than people trying to satisfy their curiosity about how the world works. “You’re marketing and selling to other scientists,” she said. “To the degree you can market and sell your products better, you’re creating the revenue stream to fund your enterprise.”
  • Universities want to attract successful scientists, and so they have erected a glut of science buildings, Dr. Stephan said. Some universities have gone into debt, betting that the flow of grant money will eventually pay off the loans.
  • “You can’t afford to fail, to have your hypothesis disproven,” Dr. Fang said. “It’s a small minority of scientists who engage in frank misconduct. It’s a much more insidious thing that you feel compelled to put the best face on everything.”
  • , Dr. Stephan points out that a number of countries — including China, South Korea and Turkey — now offer cash rewards to scientists who get papers into high-profile journals.
  • To change the system, Dr. Fang and Dr. Casadevall say, start by giving graduate students a better understanding of science’s ground rules — what Dr. Casadevall calls “the science of how you know what you know.”
  • They would also move away from the winner-take-all system, in which grants are concentrated among a small fraction of scientists. One way to do that may be to put a cap on the grants any one lab can receive.
  • Such a shift would require scientists to surrender some of their most cherished practices — the priority rule, for example, which gives all the credit for a scientific discovery to whoever publishes results first.
  • To ease such cutthroat competition, the two editors would also change the rules for scientific prizes and would have universities take collaboration into account when they decide on promotions.
  • Even scientists who are sympathetic to the idea of fundamental change are skeptical that it will happen any time soon. “I don’t think they have much chance of changing what they’re talking about,” said Dr. Korn, of Harvard.
  • “When our generation goes away, where is the new generation going to be?” he asked. “All the scientists I know are so anxious about their funding that they don’t make inspiring role models. I heard it from my own kids, who went into art and music respectively. They said, ‘You know, we see you, and you don’t look very happy.’ ”

  • We found that people might be inclined to send money to an individual person in need, but that if they heard that a second person also required aid but could not be helped, they were less inclined to donate to the first person. Meeting that need no longer felt as satisfying. Similarly, when the need for assistance was described as part of a large-scale relief effort, potential donors would experience a demotivating sense of inefficacy arising from the thought that the help they could provide was but “a drop in the bucket.”
  • It seems that we are psychologically wired to help only one person at a time. And we don’t even care to do that if we sense that there are others we cannot help.
  • In addition, we believe that yet another psychological tendency, the “prominence effect,” explains why genuinely well-meaning people (and their governments) so often fail to intervene to prevent genocides and other large-scale abuses. “Prominent” actions or objectives are those that are easily justified, though they may not match our stated social values.
  • Decisions that protect national security or satisfy our attachment to near-term comforts and conveniences are easily justified. Such choices, as Paul Slovic explains in a recent University of Illinois Law Review article, are likely to trump decisions to protect people or the environment, especially when the humans in need or the environmental phenomena in jeopardy (species, habitats, the planet’s climate) are so vast in scale as to seem distant and abstract.
  • argued decades ago, in their book “New World New Mind,” that our minds had failed to keep up with the times — that we were, in a sense, cave men and cave women, struggling to deal with modern problems, like nuclear annihilation, to which our minds were not suited. They called for a “conscious evolution” in how we processed information about the modern world, meaning an intentional change in our cognitive habits.
  • We need to be alert to how psychic numbing, pseudoinefficacy and the prominence effect lead us to act in ways contrary to our values. Doing so can help us to improve our reactions to information about a complex and often upsetting world

Dengue Mosquitoes Can Be Tamed by a Common Microbe - The Atlantic - 0 views

  • Dengue fever is caused by a virus that infects an estimated 390 million people every year, and kills about 25,000; the World Health Organization has described it as one of the top 10 threats to global health.
  • It spreads through the bites of mosquitoes, particularly the species Aedes aegypti. Utarini and her colleagues have spent the past decade turning these insects from highways of dengue into cul-de-sacs. They’ve loaded the mosquitoes with a bacterium called Wolbachia, which prevents them from being infected by dengue viruses. Wolbachia spreads very quickly: If a small number of carrier mosquitoes are released into a neighborhood, almost all of the local insects should be dengue-free within a few months
  • Aedes aegypti was once a forest insect confined to sub-Saharan Africa, where it drank blood from a wide variety of animals. But at some point, one lineage evolved into an urban creature that prefers towns over forests, and humans over other animals.
  • ...10 more annotations...
  • The World Mosquito Program (WMP), a nonprofit that pioneered this technique, had run small pilot studies in Australia that suggested it could work. Utarini, who co-leads WMP Yogyakarta, has now shown conclusively that it does.
  • Carried around the world aboard slave ships, Aedes aegypti has thrived. It is now arguably the most effective human-hunter on the planet, its senses acutely attuned to the carbon dioxide in our breath, the warmth of our bodies, and the odors of our skin.
  • Wolbachia was first discovered in 1924, in a different species of mosquito. At first, it seemed so unremarkable that scientists ignored it for decades. But starting in the 1980s, they realized that it has an extraordinary knack for spreading. It passes down mainly from insect mothers to their children, and it uses many tricks to ensure that infected individuals are better at reproducing than uninfected ones. To date, it exists in at least 40 percent of all insect species, making it one of the most successful microbes on the planet.
  • The team divided a large portion of the city into 24 zones and released Wolbachia-infected mosquitoes in half of them. Almost 10,000 volunteers helped distribute egg-filled containers to local backyards. Within a year, about 95 percent of the Aedes mosquitoes in the 12 release zones harbored Wolbachia.
  • The team found that just 2.3 percent of feverish people who lived in the Wolbachia release zones had dengue, compared with 9.4 percent in the control areas. Wolbachia also seemed to work against all four dengue serotypes, and reduced the number of dengue hospitalizations by 86 percent.
  • Even then, these already remarkable numbers are likely to be underestimates. The mosquitoes moved around, carrying Wolbachia into the 12 control zones where no mosquitoes were released. And people also move: They might live in a Wolbachia release zone but be bitten and infected with dengue elsewhere. Both of these factors would have worked against the trial, weakening its results
  • The Wolbachia method does have a few limitations. The bacterium takes months to establish itself, so it can’t be “deployed to contain an outbreak today,” Vazquez-Prokopec told me. As the Yogyakarta trial showed, it works only when Wolbachia reaches a prevalence of at least 80 percent, which requires a lot of work and strong community support
  • The method has other benefits too. It is self-amplifying and self-perpetuating: If enough Wolbachia-infected mosquitoes are released initially, the bacterium should naturally come to dominate the local population, and stay that way. Unlike insecticides, Wolbachia isn’t toxic, it doesn’t kill beneficial insects (or even mosquitoes), and it doesn’t need to be reapplied, which makes it very cost-effective.
  • An analysis by Brady’s team showed that it actually saves money by preventing infections
  • Wolbachia also seems to work against the other diseases that Aedes aegypti carries, including Zika and yellow fever. It could transform this mosquito from one of the most dangerous species to humans into just another biting nuisance.

  • Certainly during the initial spring lockdown period, our screen time increased, meaning that we were more likely to be exposed to thin or athletic ideals through the media, while decreased physical activity may have heightened negative thoughts about weight or shape. At the same time, it is possible that the additional anxiety and stress caused by COVID-19 may have diminished the coping mechanisms we typically use to help manage negative thoughts.

What Johannes Kepler Got Wrong - 0 views

  • ohannes Kepler was one of the leading characters in the history of astronomy. His most famous achievement was the three laws of planetary motion, still taught in courses today. However, like all other human beings, he was not perfect and made mistakes
  • Johannes Kepler was one of the most influential figures in the history of astronomy. His three laws of planetary movement changed the world of science significantly and became a foundation for other scientists to build theories upon.
  • Nonetheless, there are theories in his past that are not even close to reality.
  • ...10 more annotations...
  • In 1609, Kepler published a book containing the first two laws. The book also revealed his new model of the solar system, which was against what most scientists back then believed.
  • He stated that planets moved in elliptical orbits through the solar system, with the Sun located at one focus of the ellipse. Before Kepler, they believed that all orbits in the solar system were perfectly circular.
  • About ten years later, Kepler added his third law: that square of the orbital period divided by the cube of orbit’s semi-major axis is the same for all planets. Although not immediately accepted, his three laws took science to the next level. Why was he initially not appreciated?
  • Kepler applied this to the planets and stated that the solar system was built upon geometrical objects called Platonic solids that are a specific type of three-dimensional shape. They have identical sides or surfaces, edges of equal length, and angles of equal extent.
  • The model Kepler presented was based on a sequence of six spheres and the five Platonic solids, each located between two spheres. Back then, only six planets were discovered as Uranus and Neptune’s discovery took until the 18th and 19th centuries. Thus, each sphere represented one planet.
  • nitially, it seemed to explain the approximate ratios of the orbits of the six planets. It also gave a reason why there are only six planets—because there are only five Platonic shapes, each of which needs to fit between the orbit of two planets, only once
  • Kepler published this theory in detail, in his book Mysterium Cosmographicum. Despite all the value he gave to this theory, we now know how wrong it was.
  • Kepler cherished the theory as his most significant work, long after he had discovered the three laws.
  • However, the number of planets in the solar system or any other system in the universe is not predictable. Many of the numbers appearing everywhere are out of a mere accident, just like the number of planets.
  • Kepler thought his greatest achievement was the wrong solar system he drew, but it was the three laws that were so right to survive to date.

Scientists are baffled: What's up with the universe? - The Washington Post - 0 views

  • The universe is unimaginably big, and it keeps getting bigger. But astronomers cannot agree on how quickly it is growing — and the more they study the problem, the more they disagree.
  • Some scientists call this a “crisis” in cosmology. A less dramatic term in circulation is “the Hubble Constant tension.”
  • Nine decades ago, the astronomer Edwin Hubble showed that the universe is orders of magnitude vaster than previously imagined — and the whole kit and kaboodle is expanding. The rate of that expansion is a number called the Hubble Constant.
  • ...12 more annotations...
  • It’s a slippery number, however. Measurements using different techniques have produced different results, and the numbers show no sign of converging even as researchers refine their observations
  • the theorists are intrigued. They hope the Hubble Constant confusion is the harbinger of a potential major discovery — some "new physics."
  • “Any time there’s a discrepancy, some kind of anomaly, we all get very excited,”
  • “Where’s it all going to go? How’s it all going to end? That’s a big question,”
  • One idea floating around is that there could have been something called Early Dark Energy that skewed the appearance of the background radiation
  • “New physics might be that there’s some form of energy that acted in the earliest moments of the evolution of the universe. You’d get an injection of energy that’d then have to disappear,”
  • Leavitt, a then-obscure employee of the Harvard College Observatory, discovered that the intrinsically brighter stars have longer periods. This insight — Leavitt’s law — allows astronomers to know the Cepheid’s absolute luminosity, then gauge the distance to the star based on how bright or faint it appears.
  • just to be clear: The Hubble Constant in question is the rate of expansion in our “local” universe, not the rate of expansion when the background radiation was first emitted billions of years ago. Over time, the Hubble Constant isn’t constant.)
  • At the dawn of the 21st century, this Standard Model seemed to pass every observational test. And any disparities in the measurement of the Hubble Constant would surely be ironed out with further observations, scientists assumed. They had even nailed down the age of the universe precisely: 13.8 billion years.
  • “We felt really good,”
  • He added, jokingly, “We should have stopped taking data.”
  • “We are wired to use our intuition to understand things around us,” Riess said. “Most of the universe is made out of stuff that’s completely different than us. This adherence to intuition is often wildly unsuccessful in the universe.”

'SARS-like damage' seen in dead coronavirus patient in China, report says | Fox News - 0 views

  • A lung biopsy found that a man who died in China from the new coronavirus last month had lung damage reminiscent of two prior coronavirus-related outbreaks, SARS and MERS.
  • “The pathological features of COVID-19 greatly resemble those seen in SARS and Middle Eastern respiratory syndrome (MERS) coronavirus infection. In addition, the liver biopsy specimens of the patient with COVID-19 showed moderate microvascular steatosis and mild lobular and portal activity (figure 2C), indicating the injury could have been caused by either SARS-CoV-2 infection or drug-induced liver injury,” the new report published in The Lancet concluded.
  • The new coronavirus, COVID-19, has infected more than 72,000 people and killed over 1,868, far larger numbers than those who suffered from the SARS, or severe acute respiratory syndrome, or MERS, Middle East respiratory syndrome, two other coronavirus epidemics of the past two decades.

J.K. Rowling Writes about Her Reasons for Speaking out on Sex and Gender Issues - J.K. ... - 0 views

  • For people who don’t know: last December I tweeted my support for Maya Forstater, a tax specialist who’d lost her job for what were deemed ‘transphobic’ tweets. She took her case to an employment tribunal, asking the judge to rule on whether a philosophical belief that sex is determined by biology is protected in law. Judge Tayler ruled that it wasn’t.
  • All the time I’ve been researching and learning, accusations and threats from trans activists have been bubbling in my Twitter timeline. This was initially triggered by a ‘like’.
  • On one occasion, I absent-mindedly ‘liked’ instead of screenshotting. That single ‘like’ was deemed evidence of wrongthink, and a persistent low level of harassment began.
  • ...35 more annotations...
  • Months later, I compounded my accidental ‘like’ crime by following Magdalen Berns on Twitter. Magdalen was an immensely brave young feminist and lesbian who was dying of an aggressive brain tumour
  • Magdalen was a great believer in the importance of biological sex, and didn’t believe lesbians should be called bigots for not dating trans women with penises, dots were joined in the heads of twitter trans activists, and the level of social media abuse increased.
  • ‘TERF’ is an acronym coined by trans activists, which stands for Trans-Exclusionary Radical Feminist. In practice, a huge and diverse cross-section of women are currently being called TERFs and the vast majority have never been radical feminists
  • why am I doing this? Why speak up? Why not quietly do my research and keep my head down?
  • I’ve got five reasons for being worried about the new trans activism, and deciding I need to speak up.
  • Firstly, I have a charitable trust that focuses on alleviating social deprivation in Scotland, with a particular emphasis on women and children. Among other things, my trust supports projects for female prisoners and for survivors of domestic and sexual abuse. I also fund medical research into MS, a disease that behaves very differently in men and women
  • I’ve wondered whether, if I’d been born 30 years later, I too might have tried to transition. The allure of escaping womanhood would have been huge.
  • The second reason is that I’m an ex-teacher and the founder of a children’s charity, which gives me an interest in both education and safeguarding
  • The third is that, as a much-banned author, I’m interested in freedom of speech and have publicly defended i
  • The fourth is where things start to get truly personal. I’m concerned about the huge explosion in young women wishing to transition and also about the increasing numbers who seem to be detransitioning (returning to their original sex), because they regret taking steps that have, in some cases, altered their bodies irrevocably, and taken away their fertility
  • ten years ago, the majority of people wanting to transition to the opposite sex were male. That ratio has now reversed. The UK has experienced a 4400% increase in girls being referred for transitioning treatment. Autistic girls are hugely overrepresented in their numbers.
  • American physician and researcher Lisa Littman set out to explore it. In an interview, she said: ‘Parents online were describing a very unusual pattern of transgender-identification where multiple friends and even entire friend groups became transgender-identified at the same time. I would have been remiss had I not considered social contagion and peer influences as potential factors.’
  • her career took a similar hit to that suffered by Maya Forstater. Lisa Littman had dared challenge one of the central tenets of trans activism, which is that a person’s gender identity is innate, like sexual orientation. Nobody, the activists insisted, could ever be persuaded into being trans.
  • The argument of many current trans activists is that if you don’t let a gender dysphoric teenager transition, they will kill themselves.
  • the new trans activism is having (or is likely to have, if all its demands are met) a significant impact on many of the causes I support, because it’s pushing to erode the legal definition of sex and replace it with gender.
  • I want to be very clear here: I know transition will be a solution for some gender dysphoric people, although I’m also aware through extensive research that studies have consistently shown that between 60-90% of gender dysphoric teens will grow out of their dysphoria
  • As I didn’t have a realistic possibility of becoming a man back in the 1980s, it had to be books and music that got me through both my mental health issues and the sexualised scrutiny and judgement that sets so many girls to war against their bodies in their teens
  • The current explosion of trans activism is urging a removal of almost all the robust systems through which candidates for sex reassignment were once required to pass. A man who intends to have no surgery and take no hormones may now secure himself a Gender Recognition Certificate and be a woman in the sight of the law.
  • We’re living through the most misogynistic period I’ve experienced. Back in the 80s, I imagined that my future daughters, should I have any, would have it far better than I ever did, but between the backlash against feminism and a porn-saturated online culture, I believe things have got significantly worse for girls.
  • From the leader of the free world’s long history of sexual assault accusations and his proud boast of ‘grabbing them by the pussy’, to the incel (‘involuntarily celibate’) movement that rages against women who won’t give them sex, to the trans activists who declare that TERFs need punching and re-educating, men across the political spectrum seem to agree: women are asking for trouble.
  • I’ve read all the arguments about femaleness not residing in the sexed body, and the assertions that biological women don’t have common experiences, and I find them, too, deeply misogynistic and regressive
  • It’s also clear that one of the objectives of denying the importance of sex is to erode what some seem to see as the cruelly segregationist idea of women having their own biological realities or – just as threatening – unifying realities that make them a cohesive political class.
  • It isn’t enough for women to be trans allies. Women must accept and admit that there is no material difference between trans women and themselves.
  • ‘woman’ is not a costume. ‘Woman’ is not an idea in a man’s head. ‘Woman’ is not a pink brain, a liking for Jimmy Choos or any of the other sexist ideas now somehow touted as progressive. Moreover, the ‘inclusive’ language that calls female people ‘menstruators’ and ‘people with vulvas’ strikes many women as dehumanising and demeaning.
  • I’ve been in the public eye now for over twenty years and have never talked publicly about being a domestic abuse and sexual assault survivor. This isn’t because I’m ashamed those things happened to me, but because they’re traumatic to revisit and remember.
  • the scars left by violence and sexual assault don’t disappear, no matter how loved you are, and no matter how much money you’ve made. My perennial jumpiness is a family joke – and even I know it’s funny – but I pray my daughters never have the same reasons I do for hating sudden loud noises, or finding people behind me when I haven’t heard them approaching.
  • I believe the majority of trans-identified people not only pose zero threat to others, but are vulnerable for all the reasons I’ve outlined. Trans people need and deserve protection
  • So I want trans women to be safe. At the same time, I do not want to make natal girls and women less safe. When you throw open the doors of bathrooms and changing rooms to any man who believes or feels he’s a woman – and, as I’ve said, gender confirmation certificates may now be granted without any need for surgery or hormones – then you open the door to any and all men who wish to come inside. That is the simple truth.
  • On Saturday morning, I read that the Scottish government is proceeding with its controversial gender recognition plans, which will in effect mean that all a man needs to ‘become a woman’ is to say he’s one. To use a very contemporary word, I was ‘triggered’
  • I forgot the first rule of Twitter – never, ever expect a nuanced conversation – and reacted to what I felt was degrading language about women. I spoke up about the importance of sex and have been paying the price ever since. I was transphobic, I was a cunt, a bitch, a TERF, I deserved cancelling, punching and death. You are Voldemort said one person, clearly feeling this was the only language I’d understand.
  • Huge numbers of women are justifiably terrified by the trans activists; I know this because so many have got in touch with me to tell their stories. They’re afraid of doxxing, of losing their jobs or their livelihoods, and of violence.
  • But endlessly unpleasant as its constant targeting of me has been, I refuse to bow down to a movement that I believe is doing demonstrable harm in seeking to erode ‘woman’ as a political and biological class and offering cover to predators like few before it
  • I stand alongside the brave women and men, gay, straight and trans, who’re standing up for freedom of speech and thought, and for the rights and safety of some of the most vulnerable in our society: young gay kids, fragile teenagers, and women who’re reliant on and wish to retain their single sex spaces
  • The supreme irony is that the attempt to silence women with the word ‘TERF’ may have pushed more young women towards radical feminism than the movement’s seen in decades.
  • All I’m asking – all I want – is for similar empathy, similar understanding, to be extended to the many millions of women whose sole crime is wanting their concerns to be heard without receiving threats and abuse.

Reasons for COVID-19 Optimism on T-Cells and Herd Immunity - 0 views

  • It may well be the case that some amount of community protection kicks in below 60 percent exposure, and possibly quite a bit below that threshold, and that those who exhibit a cross-reactive T-cell immune response, while still susceptible to infection, may also have some meaningful amount of protection against severe disease.
  • early returns suggest that while the maximalist interpretation of each hypothesis is not very credible — herd immunity has probably not been reached in many places, and cross-reactive T-cell response almost certainly does not functionally immunize those who have it — more modest interpretations appear quite plausible.
  • Friston suggested that the truly susceptible portion of the population was certainly not 100 percent, as most modelers and conventional wisdom had it, but a much smaller share — surely below 50 percent, he said, and likely closer to about 20 percent. The analysis was ongoing, he said, but, “I suspect, once this has been done, it will look like the effective non-susceptible portion of the population will be about 80 percent. I think that’s what’s going to happen.”
  • ...31 more annotations...
  • one of the leading modelers, Gabriela Gomes, suggested the entire area of research was being effectively blackballed out of fear it might encourage a relaxation of pandemic vigilance. “This is the very sad reason for the absence of more optimistic projections on the development of this pandemic in the scientific literature,” she wrote on Twitter. “Our analysis suggests that herd-immunity thresholds are being achieved despite strict social-distancing measures.”
  • Gomes suggested, herd immunity could happen with as little as one quarter of the population of a community exposed — or perhaps just 20 percent. “We just keep running the models, and it keeps coming back at less than 20 percent,” she told Hamblin. “It’s very striking.” Such findings, if they held up, would be very instructive, as Hamblin writes: “It would mean, for instance, that at 25 percent antibody prevalence, New York City could continue its careful reopening without fear of another major surge in cases.”
  • But for those hoping that 25 percent represents a true ceiling for pandemic spread in a given community, well, it almost certainly does not, considering that recent serological surveys have shown that perhaps 93 percent of the population of Iquitos, Peru, has contracted the disease; as have more than half of those living in Indian slums; and as many as 68 percent in particular neighborhoods of New York City
  • overshoot of that scale would seem unlikely if the “true” threshold were as low as 20 or 25 percent.
  • But, of course, that threshold may not be the same in all places, across all populations, and is surely affected, to some degree, by the social behavior taken to protect against the spread of the disease.
  • we probably err when we conceive of group immunity in simplistically binary terms. While herd immunity is a technical term referring to a particular threshold at which point the disease can no longer spread, some amount of community protection against that spread begins almost as soon as the first people are exposed, with each case reducing the number of unexposed and vulnerable potential cases in the community by one
  • you would not expect a disease to spread in a purely exponential way until the point of herd immunity, at which time the spread would suddenly stop. Instead, you would expect that growth to slow as more people in the community were exposed to the disease, with most of them emerging relatively quickly with some immune response. Add to that the effects of even modest, commonplace protections — intuitive social distancing, some amount of mask-wearing — and you could expect to get an infection curve that tapers off well shy of 60 percent exposure.
  • Looking at the data, we see that transmissions in many severely impacted states began to slow down in July, despite limited interventions. This is especially notable in states like Arizona, Florida, and Texas. While we believe that changes in human behavior and changes in policy (such as mask mandates and closing of bars/nightclubs) certainly contributed to the decrease in transmission, it seems unlikely that these were the primary drivers behind the decrease. We believe that many regions obtained a certain degree of temporary herd immunity after reaching 10-35 percent prevalence under the current conditions. We call this 10-35 percent threshold the effective herd immunity threshold.
  • Indeed, that is more or less what was recently found by Youyang Gu, to date the best modeler of pandemic spread in the U.S
  • he cautioned again that he did not mean to imply that the natural herd-immunity level was as low as 10 percent, or even 35 percent. Instead, he suggested it was a plateau determined in part by better collective understanding of the disease and what precautions to take
  • Gu estimates national prevalence as just below 20 percent (i.e., right in the middle of his range of effective herd immunity), it still counts, I think, as encouraging — even if people in hard-hit communities won’t truly breathe a sigh of relief until vaccines arrive.
  • If you can get real protection starting at 35 percent, it means that even a mediocre vaccine, administered much more haphazardly to a population with some meaningful share of vaccination skeptics, could still achieve community protection pretty quickly. And that is really significant — making both the total lack of national coordination on rollout and the likely “vaccine wars” much less consequential.
  • At least 20 percent of the public, and perhaps 50 percent, had some preexisting, cross-protective T-cell response to SARS-CoV-2, according to one much-discussed recent paper. An earlier paper had put the figure at between 40 and 60 percent. And a third had found an even higher prevalence: 81 percent.
  • The T-cell story is similarly encouraging in its big-picture implications without being necessarily paradigm-changing
  • These numbers suggest their own heterogeneity — that different populations, with different demographics, would likely exhibit different levels of cross-reactive T-cell immune response
  • The most optimistic interpretation of the data was given to me by Francois Balloux, a somewhat contrarian disease geneticist and the director of the University College of London’s Genetics Institute
  • According to him, a cross-reactive T-cell response wouldn’t prevent infection, but would probably mean a faster immune response, a shorter period of infection, and a “massively” reduced risk of severe illness — meaning, he guessed, that somewhere between a third and three-quarters of the population carried into the epidemic significant protection against its scariest outcomes
  • the distribution of this T-cell response could explain at least some, and perhaps quite a lot, of COVID-19’s age skew when it comes to disease severity and mortality, since the young are the most exposed to other coronaviruses, and the protection tapers as you get older and spend less time in environments, like schools, where these viruses spread so promiscuously.
  • Balloux told me he believed it was also possible that the heterogeneous distribution of T-cell protection also explains some amount of the apparent decline in disease severity over time within countries on different pandemic timelines — a phenomenon that is more conventionally attributed to infection spreading more among the young, better treatment, and more effective protection of the most vulnerable (especially the old).
  • Going back to Youyang Gu’s analysis, what he calls the “implied infection fatality rate” — essentially an estimated ratio based on his modeling of untested cases — has fallen for the country as a whole from about one percent in March to about 0.8 percent in mid-April, 0.6 percent in May, and down to about 0.25 percent today.
  • even as we have seemed to reach a second peak of coronavirus deaths, the rate of death from COVID-19 infection has continued to decline — total deaths have gone up, but much less than the number of cases
  • In other words, at the population level, the lethality of the disease in America has fallen by about three-quarters since its peak. This is, despite everything that is genuinely horrible about the pandemic and the American response to it, rather fantastic.
  • there may be some possible “mortality displacement,” whereby the most severe cases show up first, in the most susceptible people, leaving behind a relatively protected population whose experience overall would be more mild, and that T-cell response may play a significant role in determining that susceptibility.
  • That, again, is Balloux’s interpretation — the most expansive assessment of the T-cell data offered to me
  • The most conservative assessment came from Sarah Fortune, the chair of Harvard’s Department of Immunology
  • Fortune cautioned not to assume that cross-protection was playing a significant role in determining severity of illness in a given patient. Those with such a T-cell response, she told me, would likely see a faster onset of robust response, yes, but that may or may not yield a shorter period of infection and viral shedding
  • Most of the scientists, doctors, epidemiologists, and immunologists I spoke to fell between those two poles, suggesting the T-cell cross-immunity findings were significant without necessarily being determinative — that they may help explain some of the shape of pandemic spread through particular populations, but only some of the dynamics of that spread.
  • he told me he believed, in the absence of that data, that T-cell cross-immunity from exposure to previous coronaviruses “might explain different disease severity in different people,” and “could certainly be part of the explanation for the age skew, especially for why the very young fare so well.”
  • the headline finding was quite clear and explicitly stated: that preexisting T-cell response came primarily via the variety of T-cells called CD4 T-cells, and that this dynamic was consistent with the hypothesis that the mechanism was inherited from previous exposure to a few different “common cold” coronaviruses
  • “This potential preexisting cross-reactive T-cell immunity to SARS-CoV-2 has broad implications,” the authors wrote, “as it could explain aspects of differential COVID-19 clinical outcomes, influence epidemiological models of herd immunity, or affect the performance of COVID-19 candidate vaccines.”
  • “This is at present highly speculative,” they cautioned.

  • You will hear, variously, that the “survival rate” for COVID is 99.0 percent, or 99.5 percent, or 99.8 percent.
  • These numbers are all statistical constructs based on the age distribution of a given population. The older your society, the lower your survival rate. But just for fun, let’s pretend it’s 99.8 percent.
  • If 99.8 percent of people who experience a rare event survive, then that number is comforting. If 99.8 percent of people survived being bitten by a shark, for instance, you’d think this was encouraging.

  • On the other hand, if you’re talking about 99.8 percent of a common event which translates into some very large number . . . well, suddenly it’s not great, Bob:
  • 2,900,000 passengers fly on airlines each day. If 99.8% of them made it safely to their destinations, 5,800 people a day would be dying in crashes and people like you would never step on an airplane ever again.July 25th 20211 Retweet4 Likes
