How the leading coronavirus vaccines made it to the finish line - The Washington Post - 0 views

  • If, as expected in the next few weeks, regulators give those vaccines the green light, the technology and the precision approach to vaccine design could turn out to be the pandemic’s silver linings: scientific breakthroughs that could begin to change the trajectory of the virus this winter and also pave the way for highly effective vaccines and treatments for other diseases.
  • Vaccine development typically takes years, even decades. The progress of the last 11 months shifts the paradigm for what’s possible, creating a new model for vaccine development and a toolset for a world that will have to fight more never-before-seen viruses in years to come.
  • Long before the pandemic, Graham worked with colleagues there and in academia to create a particularly accurate 3-D version of the spiky proteins that protrude from the surface of coronaviruses — an innovation that was rejected for publication by scientific journals five times because reviewers questioned its relevance.
  • ...26 more annotations...
  • Messenger RNA is a powerful, if fickle, component of life’s building blocks — a workhorse of the cell that is also truly just a messenger, unstable and prone to degrade.
  • . In 1990,
  • That same year, a team at the University of Wisconsin startled the scientific world with a paper that showed it was possible to inject a snippet of messenger RNA into mice and turn their muscle cells into factories, creating proteins on demand.
  • If custom-designed RNA snippets could be used to turn cells into bespoke protein factories, messenger RNA could become a powerful medical tool. It could encode fragments of virus to teach the immune system to defend against pathogens. It could also create whole proteins that are missing or damaged in people with devastating genetic diseases, such as cystic fibrosis.
  • In 2005, the pair discovered a way to modify RNA, chemically tweaking one of the letters of its code, so it didn’t trigger an inflammatory response. Deborah Fuller, a scientist who works on RNA and DNA vaccines at the University of Washington, said that work deserves a Nobel Prize.
  • messenger RNA posed a bigger challenge than other targets.“It’s tougher — it’s a much bigger molecule, it’s much more unstable,”
  • Unlike fields that were sparked by a single powerful insight, Sahin said that the recent success of messenger RNA vaccines is a story of countless improvements that turned an alluring biological idea into a beneficial technology.
  • “This is a field which benefited from hundreds of inventions,” said Sahin, who noted that when he started BioNTech in 2008, he cautioned investors that the technology would not yield a product for at least a decade. He kept his word: Until the coronavirus sped things along, BioNTech projected the launch of its first commercial project in 2023.
  • “It’s new to you,” Fuller said. “But for basic researchers, it’s been long enough. . . . Even before covid, everyone was talking: RNA, RNA, RNA.”
  • All vaccines are based on the same underlying idea: training the immune system to block a virus. Old-fashioned vaccines do this work by injecting dead or weakened viruses
  • ewer vaccines use distinctive bits of the virus, such as proteins on their surface, to teach the lesson. The latest genetic techniques, like messenger RNA, don’t take as long to develop because those virus bits don’t have to be generated in a lab. Instead, the vaccine delivers a genetic code that instructs cells to build those characteristic proteins themselves.
  • They wanted the immune system to learn to recognize the thumb tack spike, so McLellan tasked a scientist in his laboratory with identifying genetic mutations that could anchor the protein into the right configuration. It was a painstaking process for Nianshuang Wang, who now works at a biotechnology company, Regeneron Pharmaceuticals. After trying hundreds of genetic mutations, he found two that worked. Five journals rejected the finding, questioning its significance, before it was published in 2017.
  • That infection opened Graham’s eyes to an opportunity. HKU1 was merely a nuisance, as opposed to a deadly pneumonia; that meant it would be easier to work with in the lab, since researchers wouldn’t have to don layers of protective gear and work in a pressurized laboratory.
  • Severe acute respiratory syndrome had emerged in 2003. Middle East respiratory syndrome (MERS) broke out in 2012. It seemed clear to Graham and Jason McLellan, a structural biologist now at the University of Texas at Austin, that new coronaviruses were jumping into people on a 10-year-clock and it might be time to brace for the next one.
  • Last winter, when Graham heard rumblings of a new coronavirus in China, he brought the team back together. Once its genome was shared online by Chinese scientists, the laboratories in Texas and Maryland designed a vaccine, utilizing the stabilizing mutations and the knowledge they had gained from years of basic research — a weekend project thanks to the dividends of all that past work.
  • Graham needed a technology that could deliver it into the body — and had already been working with Moderna, using its messenger RNA technology to create a vaccine against a different bat virus, Nipah, as a dress rehearsal for a real pandemic. Moderna and NIH set the Nipah project aside and decided to go forward with a coronavirus vaccine.
  • On Jan. 13, Moderna’s Moore came into work and found her team already busy translating the stabilized spike protein into their platform. The company could start making the vaccine almost right away because of its experience manufacturing experimental cancer vaccines, which involves taking tumor samples and developing personalized vaccines in 45 days.
  • At BioNTech, Sahin said that even in the early design phases of its vaccine candidates, he incorporated the slight genetic changes designed in Graham’s lab that would make the spike look more like the real thing. At least two other companies would incorporate that same spike.
  • If all goes well with regulators, the coronavirus vaccines have the makings of a pharmaceutical industry fairy tale. The world faced an unparalleled threat, and companies leaped into the fight. Pfizer plowed $2 billion into the effort. Massive infusions of government cash helped remove the financial risks for Moderna.
  • But the world will also owe their existence to many scientists outside those companies, in government and academia who pursued ideas they thought were important even when the world doubted them
  • Some of those scientists will receive remuneration, since their inventions are licensed and integrated into the products that could save the world.
  • As executives become billionaires, many scientists think it is fair to earn money from their inventions that can help them do more important work. But McLellan’s laboratory at the University of Texas is proud to have licensed an even more potent version of their spike protein, royalty-free, to be incorporated into a vaccine for low and middle income countries.
  • “They’re using the technology that [Kariko] and I developed,” he said. “We feel like it’s our vaccine, and we are incredibly excited — at how well it’s going, and how it’s going to be used to get rid of this pandemic.”
  • “People hear about [vaccine progress] and think someone just thought about it that night. The amount of work — it’s really a beautiful story of fundamental basic research,” Fauci said. “It was chancy, in the sense that [the vaccine technology] was new. We were aware there would be pushback. The proof in the pudding is a spectacular success.”
  • The Vaccine Research Center, where Graham is deputy director, was the brainchild of Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases. It was created in 1997 to bring together scientists and physicians from different disciplines to defeat diseases, with a heavy focus on HIV.
  • the pandemic wasn’t a sudden eureka moment — it was a catalyst that helped ignite lines of research that had been moving forward for years, far outside the spotlight of a global crisis.

Climate Change: The Technologies That Could Make All the Difference - WSJ - 0 views

  • The modularity of DAC systems implies that costs for CO2 removal might drop 90% to 95% over a couple of decades, just like the recent cost declines for other modular solutions such as wind turbines, solar panels and lithium-ion batteries.
  • Unlike other pollutants, what matters with carbon dioxide isn’t the location of its release but the total atmospheric accumulation. Releasing greenhouse gases in industrial corridors and then removing them from the atmosphere in remote locations has essentially the same net effect as if the carbon wasn’t emitted in the first place. That means we can deploy DAC systems wherever the energy for their operation is cheapest, ecosystem impacts are lowest, and the economic activity would be welcome.
  • A solar microgrid, which generates, stores and distributes clean energy to homes and facilities in a local network, provides a strong answer to these needs and wants. It can integrate with the main electric grid or disconnect and operate autonomously if the main grid is stressed or goes down. The physical pieces—solar panels, batteries and inverters—have been improving for a while. What’s new and coming, though, is the ability to orchestrate these different pieces into agile electric grids.
  • ...18 more annotations...
  • With digital tools and data science, demand for energy can now be sculpted locally to match available resources, reducing the number of power plants that utilities need to keep in reserve.
  • The key is giving consumers the ability to separate flexible energy uses—say, operating a Jacuzzi—from essential needs, which can now be done with phone apps for smart appliances and service panels.
  • Meanwhile, connections between groups of customers can be opened and closed as needed with modern, communicating circuit switchgear.
  • The good news is that record amounts of batteries are being installed in U.S. homes and on the electric grid, despite supply-chain bottlenecks.
  • The bad news is that current battery technology only offers a few hours of storage. What’s needed are more-powerful battery systems that can extend the length or scale of storing, which could be even more enabling to sun and wind power.
  • Two such solutions are on the horizon. Stationary metal-air batteries, such as iron-air batteries, don’t hold as much energy per kilogram as lithium-ion batteries so it takes a larger, heavier battery to do the job. But they are cheaper, iron is a plentiful metal, and the batteries, whose chemistry works via interaction of the metal with air, can be sized and installed to store and discharge a large level of electricity over days or weeks.
  • improved large iron-air batteries are poised to become a great new backup for renewable energy within the next couple of years to address those times of year when drops in renewable energy production can last for days and not hours.
  • For households, a battery configuration called a virtual power plant also holds huge potential to extend the use of renewables. These systems allow a local utility or electricity distributor to collect excess energy stored in multiple households’ battery systems and feed it back to the grid when there is a surge in demand or generation shortfall.
  • Electrification is a good choice for smaller vessels on short voyages, like the world’s largest all-electric ferry launched in Norway in 2021. It isn’t yet a viable option for ships on transoceanic voyages because batteries are still too large and heavy, though innovative approaches for battery swapping are being explored.
  • Greener Shipping
  • For longer voyages, e-ammonia, a hydrogen-derived fuel made with renewable energy, has been identified as a prime candidate, although work is needed to ensure safety. Ammonia has a higher energy density than some other options, making it a more economical option for powering large ships across oceans.
  • Among ammonia projects in the works, MAN Energy Solutions is developing engines that can run on conventional fossil fuel or ammonia, a coalition of Nordic partners is designing the world’s first ammonia-powered vessel, and Singapore is evaluating how to bunker the fuel.
  • Some EV makers such as Tesla are now embracing an older, less-expensive battery technology known as lithium-iron-phosphate, or LFP, used originally in scooters and small EVs in China
  • . It draws entirely on cheap and abundant minerals and is less flammable. The power density of LFP is less than NMC, but that disadvantage can be overcome by advances in vehicle design.
  • One approach being tested eliminates the outer packaging of the batteries altogether and directly installs cells, packed in layers, into a cavity in the EV’s body chassis.
  • Eventually, solid-state batteries—with a solid electrolyte made from common minerals like glass or ceramics—could become a key EV battery technology.
  • The solid electrolyte is more chemically stable, lighter, recharges faster and has many more lifetime recharging cycles than lithium-ion batteries, which depend on heavy liquid electrolytes.
  • these innovations are good news for those hoping to speed up EV adoption. They also suggest that batteries, far from becoming a standardized commodity, are going to be customized as auto makers create their own vehicle designs and battery makers develop proprietary platforms.

Matt Ridley on Evolution by Sexual Selection | Mind & Matter - WSJ.com - 0 views

  • the evolutionary psychologist Geoffrey Miller in his book "The Mating Mind" explored the notion that since human males woo their mates with art, poetry, music and humor, as well as with brawn, much of the expansion of our brain may have been sexually selected.
  • sexual selection explains civilization itself. They mathematically explored the possibility that "as females prefer males who conspicuously consume, an increasing proportion of males engage in innovation, labor and other productive activities in order to engage in conspicuous consumption. These activities contribute to technological progress and economic growth.
  • Michael Shermer, in his book "The Mind of the Market," argues that you can trace anticapitalist egalitarianism to sexual selection. Back in the hunter-gatherer Paleolithic, inequality had reproductive consequences. The successful hunter, providing valuable protein for females, got a lot more mating opportunities than the unsuccessful.
  • ...1 more annotation...
  • this might explain why it is relative, rather than absolute, inequality that matters so much to people today. In modern Western society, when even relatively poor people have access to transport, refrigeration, entertainment, shoes and plentiful food, you might expect that inequality would be less resented than a century ago—when none of those things might come within the reach of a poor person. What does it matter if there are people who can afford private jets and designer dresses? But clearly that isn't how people think. They resent inequality in luxuries just as much if not more than inequality in necessities. They dislike (and envy) conspicuous consumption, even if it impinges on them not at all. What hurts is not that somebody is rich, but that he is richer.

A 5-Step Technique for Producing Ideas circa 1939 | Brain Pickings - 0 views

  • In learning any art the important things to learn are, first, Principles, and second, Method. This is true of the art of producing ideas. Particular bits of knowledge are nothing, because they are made up [of] so called rapidly aging facts. Principles and method are everything.
  • So with the art of producing ideas. What is most valuable to know is not where to look for a particular idea, but how to train the mind in the method by which all ideas are produced and how to grasp the principles which are at the source of all ideas.
  • Every really good creative person…whom I have ever known has always had two noticeable characteristics. First, there was no subject under the sun in which he could not easily get interested — from, say, Egyptian burial customs to modern art. Every facet of life had fascination for him. Second, he was an extensive browser in all sorts of fields of information.
  • ...7 more annotations...
  • What you do is to take the different bits of material which you have gathered and feel them all over, as it were, with the tentacles of the mind. You take one fact, turn it this way and that, look at it in different lights, and feel for the meaning of it. You bring two facts together and see how they fit. What you are seeking now is the relationship, a synthesis where everything will come together in a neat combination, like a jig-saw puzzle.
  • Then and only then, Young promises, everything will click in the fourth stage of the seemingly serendipitous a-ha! moment: Out of nowhere the Idea will appear. It will come to you when you are least expecting it
  • In his third stage of the creative process, Young stresses the importance of making absolutely “no effort of a direct nature”: It is important to realize that this is just as definite and just as necessary a stage in the process as the two preceding ones. What you have to do at this time, apparently, is to turn the problem over to your unconscious mind and let it work while you sleep.
  • [W]hen you reach this third stage in the production of an idea, drop the problem completely and turn to whatever stimulates your imagination and emotions. Listen to music, go to the theater or movies, read poetry or a detective story.
  • articulates the increasing importance of quality information filters in our modern information diet. This notion of gathering raw material is the first step in his outline of the creative process:
  • Young calls the last stage “the cold, gray dawn of the morning after,” when your newborn idea has to face reality: It requires a deal of patient working over to make most ideas fit the exact conditions, or the practical exigencies, under which they must work. And here is where many good ideas are lost. The idea man, like the inventor, is often not patient enough or practical enough to go through with this adapting part of the process. But it has to be done if you are to put ideas to work in a work-a-day world. Do not make the mistake of holding your idea close to your chest at this stage. Submit it to the criticism of the judicious. When you do, a surprising thing will happen. You will find that a good idea has, as it were, self-expanding qualities. It stimulates those who see it to add to it. Thus possibilities in it which you have overlooked will come to light.
  • what’s perhaps most interesting is the following note he made to the postscript of a reprint: From my own further experience in advertising, government, and public affairs I find no essential points which I would modify in the idea-producing process. There is one, however, on which I would put greater emphasis. This is as to the store of general materials in the idea-producer’s reservoir. […] I am convinced, however, that you gather this vicarious experience best, not when you are boning up on it for an immediate purpose, but when you are pursuing it as an end in itself.

The Atheist's Belief In Medicine « The Dish - 1 views

  • Hitchens’s beliefs about his advanced cancer and its treatment were, for a man whose fame rested on his scepticism, uncharacteristically optimistic. I hesitate to use the word delusional, as he admitted that he would be very lucky to survive, but he clearly steadfastly hoped, right to the end, that his particular case of advanced cancer might lie on the sparsely populated right side of the bell-shaped curve of outcome statistics.
  • I wonder if all that medicine – which was, in fact, a form of poison – was worth it. David got ten more years, and two young children. But he also endured a disfiguring, disabling, brutal physical battering from the surgeries and chemo-sessions that tackling a tough brain tumor allow for. I say “allow for” because “required” is not the right word. What the chemo did to Christopher was beyond description – and what’s left of your body, even if the chemo works, can be extremely vulnerable to infections and diseases that can be worse than the cancer.
  • It seems odder to me for Christians to be as exercized by life-extension as the atheist. Put that down to the strange extremism of Ratzinger’s innovations on the question of “life”.
  • ...6 more annotations...
  • No one should seek to die or give in to a disease they can legitimately fight. God knows how many pills I take a day to keep the virus – and all its and their side-effects at bay. But I get to live healthily and meaningfully. The way some elaborate and cutting edge treatments all but kill the patient in order to save her troubles me. It’s a loss of perspective as well as immensely expensive for the entire system.
  • our culture’s gradual alienation from the fact of our deaths – our distancing ourselves even from the old and infirm in ways previous cultures didn’t and couldn’t – is not, in my view a healthy thing.
  • these sophisticated treatments are taking healthcare money away from the young, taking up more and more of our collective healthcare resources, and extending lives only be perpetuating continuous agony and nausea and pain for the patient and devastating consequences for families and friends.

The Signal and the Noise: Why So Many Predictions Fail-but Some Don't: Nate Silver: 978... - 0 views

  • Nate Silver built an innovative system for predicting baseball performance, predicted the 2008 election within a hair’s breadth, and became a national sensation as a blogger—all by the time he was thirty. The New York Times now publishes FiveThirtyEight.com, where Silver is one of the nation’s most influential political forecasters.
  • Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the “prediction paradox”: The more humility we have about our ability to make predictions, the more successful we can be in planning for the future.
  • the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise.

  • Baseball, weather forecasting, earthquake prediction, economics, and polling: In all of these areas, Silver finds predictions gone bad thanks to biases, vested interests, and overconfidence. But he also shows where sophisticated forecasters have gotten it right (and occasionally been ignored to boot)
  • This is the best general-readership book on applied statistics that I've read. Short review: if you're interested in science, economics, or prediction: read it. It's full of interesting cases, builds intuition, and is a readable example of Bayesian thinking.
  • The core concept is this: prediction is a vital part of science, of business, of politics, of pretty much everything we do. But we're not very good at it, and fall prey to cognitive biases and other systemic problems such as information overload that make things worse. However, we are simultaneously learning more about how such things occur and that knowledge can be used to make predictions better -- and to improve our models in science, politics, business, medicine, and so many other areas.

How Facebook Warps Our Worlds - The New York Times - 0 views

  • THOSE who’ve been raising alarms about Facebook are right: Almost every minute that we spend on our smartphones and tablets and laptops, thumbing through favorite websites and scrolling through personalized feeds, we’re pointed toward foregone conclusions. We’re pressured to conform
  • We’re the real culprits. When it comes to elevating one perspective above all others and herding people into culturally and ideologically inflexible tribes, nothing that Facebook does to us comes close to what we do to ourselves.
  • I’m talking about how we use social media in particular and the Internet in general — and how we let them use us. They’re not so much agents as accomplices, new tools for ancient impulses, part of “a long sequence of technological innovations that enable us to do what we want

  • prevalent for many users are the posts we see from friends and from other people and groups we follow on the network, and this information is utterly contingent on choices we ourselves make
  • The Internet isn’t rigged to give us right or left, conservative or liberal — at least not until we rig it that way. It’s designed to give us more of the same, whatever that same is
  • So it goes with the fiction we read, the movies we watch, the music we listen to and, scarily, the ideas we subscribe to. They’re not challenged. They’re validated and reinforced.
  • this colors our days, or rather bleeds them of color, reducing them to a single hue.
  • Facebook, along with other social media, definitely conspires in this. Haidt noted that it often discourages dissent within a cluster of friends by accelerating shaming. He pointed to the enforced political correctness among students at many colleges.
  • Carnival barkers, conspiracy theories, willful bias and nasty partisanship aren’t anything new, and they haven’t reached unprecedented heights today. But what’s remarkable and sort of heartbreaking is the way they’re fed by what should be strides in our ability to educate ourselves.
  • The proliferation of cable television networks and growth of the Internet promised to expand our worlds, not shrink them. Instead they’ve enhanced the speed and thoroughness with which we retreat into enclaves of the like-minded.
  • there’s no argument that in an era that teems with choice, brims with niche marketing and exalts individualism to the extent that ours does, we’re sorting ourselves with a chillingly ruthless efficiency. We’ve surrendered universal points of reference. We’ve lost common ground.
  • Marc Dunkelman, adding that it also makes it easier for us to avoid “face-to-face interactions with diverse ideas.” He touched on this in an incisive 2014 book, “The Vanishing Neighbor,” which belongs with Haidt’s work and with “Bowling Alone,” “Coming Apart” and “The Fractured Republic” in the literature of modern American fragmentation, a booming genre all its own.
  • We’re less committed to, and trustful of, large institutions than we were at times in the past. We question their wisdom and substitute it with the groupthink of micro-communities, many of which we’ve formed online, and their sensibilities can be more peculiar and unforgiving.
  • We construct precisely contoured echo chambers of affirmation that turn conviction into zeal, passion into fury, disagreements with the other side into the demonization of it
  • It’s not about some sorcerer’s algorithm. It’s about a tribalism that has existed for as long as humankind has and is now rooted in the fertile soil of the Internet, which is coaxing it toward a full and insidious flower

The Downward Slide of the Seesaw - The New York Times - 0 views

  • The older seesaws were wooden planks that often hit asphalt directly, leading to occasional tailbone and spinal injuries, falls and pinched fingers, not to mention splinters. Children could slam each other by dismounting suddenly. Playgrounds that retained old seesaws were exposed to lawsuits.
  • “I think we have to take the kids out a little bit from the safety bubble,” she said, placing her 2-year-old daughter, Sadie, on a seesaw too.
  • “One little fall or a tooth broken and the next thing you know they are out,” she said.

  • As a result, relatively few playground injuries are now attributable to seesaws. According to data collected by the United States Consumer Product Safety Commission, which sets the safety standards, the top three pieces of equipment associated with emergency room visits between 2009 and 2014 were monkey bars, swings and slides. Only 2 percent of injuries were from teeter-totters.
  • “A seemingly simple plaything actually provides so many important sensory experiences for kids,” she said.
  • “The more we live with the safety standards, the more you see people kind of innovating to bring back types of experiences that maybe for a while you weren’t seeing,” she said. “There’s no reason to think we won’t have traditional seesaws in the park at some point.”
  •  
    This article mentioned a conflict between safety and experience. Can we be both safe and get the experience of overcoming difficulty? Obviously, we have to sacrifice one thing to get another. I think removing the seesaw is not a good idea if we just do it out of the concern of safety. We can never stay in our comfort zoom because once we grow up, we won't have our parents to protect us every time. Something related to TOK is that our mental shortcut of avoiding danger may not always benefit us. --Sissi (12/14/2016)

[Six Questions] | Astra Taylor on The People's Platform: Taking Back Power and Culture ... - 1 views

  • Astra Taylor, a cultural critic and the director of the documentaries Zizek! and Examined Life, challenges the notion that the Internet has brought us into an age of cultural democracy. While some have hailed the medium as a platform for diverse voices and the free exchange of information and ideas, Taylor shows that these assumptions are suspect at best. Instead, she argues, the new cultural order looks much like the old: big voices overshadow small ones, content is sensationalist and powered by advertisements, quality work is underfunded, and corporate giants like Google and Facebook rule. The Internet does offer promising tools, Taylor writes, but a cultural democracy will be born only if we work collaboratively to develop the potential of this powerful resource
  • Most people don’t realize how little information can be conveyed in a feature film. The transcripts of both of my movies are probably equivalent in length to a Harper’s cover story.
  • why should Amazon, Apple, Facebook, and Google get a free pass? Why should we expect them to behave any differently over the long term? The tradition of progressive media criticism that came out of the Frankfurt School, not to mention the basic concept of political economy (looking at the way business interests shape the cultural landscape), was nowhere to be seen, and that worried me. It’s not like political economy became irrelevant the second the Internet was invented.

  • How do we reconcile our enjoyment of social media even as we understand that the corporations who control them aren’t always acting in our best interests?
  • hat was because the underlying economic conditions hadn’t been changed or “disrupted,” to use a favorite Silicon Valley phrase. Google has to serve its shareholders, just like NBCUniversal does. As a result, many of the unappealing aspects of the legacy-media model have simply carried over into a digital age — namely, commercialism, consolidation, and centralization. In fact, the new system is even more dependent on advertising dollars than the one that preceded it, and digital advertising is far more invasive and ubiquitous
  • the popular narrative — new communications technologies would topple the establishment and empower regular people — didn’t accurately capture reality. Something more complex and predictable was happening. The old-media dinosaurs weren’t dying out, but were adapting to the online environment; meanwhile the new tech titans were coming increasingly to resemble their predecessors
  • I use lots of products that are created by companies whose business practices I object to and that don’t act in my best interests, or the best interests of workers or the environment — we all do, since that’s part of living under capitalism. That said, I refuse to invest so much in any platform that I can’t quit without remorse
  • these services aren’t free even if we don’t pay money for them; we pay with our personal data, with our privacy. This feeds into the larger surveillance debate, since government snooping piggybacks on corporate data collection. As I argue in the book, there are also negative cultural consequences (e.g., when advertisers are paying the tab we get more of the kind of culture marketers like to associate themselves with and less of the stuff they don’t) and worrying social costs. For example, the White House and the Federal Trade Commission have both recently warned that the era of “big data” opens new avenues of discrimination and may erode hard-won consumer protections.
  • I’m resistant to the tendency to place this responsibility solely on the shoulders of users. Gadgets and platforms are designed to be addictive, with every element from color schemes to headlines carefully tested to maximize clickability and engagement. The recent news that Facebook tweaked its algorithms for a week in 2012, showing hundreds of thousands of users only “happy” or “sad” posts in order to study emotional contagion — in other words, to manipulate people’s mental states — is further evidence that these platforms are not neutral. In the end, Facebook wants us to feel the emotion of wanting to visit Facebook frequently
  • social inequalities that exist in the real world remain meaningful online. What are the particular dangers of discrimination on the Internet?
  • That it’s invisible or at least harder to track and prove. We haven’t figured out how to deal with the unique ways prejudice plays out over digital channels, and that’s partly because some folks can’t accept the fact that discrimination persists online. (After all, there is no sign on the door that reads Minorities Not Allowed.)
  • just because the Internet is open doesn’t mean it’s equal; offline hierarchies carry over to the online world and are even amplified there. For the past year or so, there has been a lively discussion taking place about the disproportionate and often outrageous sexual harassment women face simply for entering virtual space and asserting themselves there — research verifies that female Internet users are dramatically more likely to be threatened or stalked than their male counterparts — and yet there is very little agreement about what, if anything, can be done to address the problem.
  • What steps can we take to encourage better representation of independent and non-commercial media? We need to fund it, first and foremost. As individuals this means paying for the stuff we believe in and want to see thrive. But I don’t think enlightened consumption can get us where we need to go on its own. I’m skeptical of the idea that we can shop our way to a better world. The dominance of commercial media is a social and political problem that demands a collective solution, so I make an argument for state funding and propose a reconceptualization of public media. More generally, I’m struck by the fact that we use these civic-minded metaphors, calling Google Books a “library” or Twitter a “town square” — or even calling social media “social” — but real public options are off the table, at least in the United States. We hand the digital commons over to private corporations at our peril.
  • 6. You advocate for greater government regulation of the Internet. Why is this important?
  • I’m for regulating specific things, like Internet access, which is what the fight for net neutrality is ultimately about. We also need stronger privacy protections and restrictions on data gathering, retention, and use, which won’t happen without a fight.
  • I challenge the techno-libertarian insistence that the government has no productive role to play and that it needs to keep its hands off the Internet for fear that it will be “broken.” The Internet and personal computing as we know them wouldn’t exist without state investment and innovation, so let’s be real.
  • there’s a pervasive and ill-advised faith that technology will promote competition if left to its own devices (“competition is a click away,” tech executives like to say), but that’s not true for a variety of reasons. The paradox of our current media landscape is this: our devices and consumption patterns are ever more personalized, yet we’re simultaneously connected to this immense, opaque, centralized infrastructure. We’re all dependent on a handful of firms that are effectively monopolies — from Time Warner and Comcast on up to Google and Facebook — and we’re seeing increased vertical integration, with companies acting as both distributors and creators of content. Amazon aspires to be the bookstore, the bookshelf, and the book. Google isn’t just a search engine, a popular browser, and an operating system; it also invests in original content
  • So it’s not that the Internet needs to be regulated but that these big tech corporations need to be subject to governmental oversight. After all, they are reaching farther and farther into our intimate lives. They’re watching us. Someone should be watching them.

A new atlas maps word meanings in the brain | PBS NewsHour - 0 views

  • The research on the “brain dictionary” has the hallmarks of a big scientific splash: Published on Wednesday in Nature, it’s accompanied by both a video and an interactive website where you can click your way from brain region to brain region, seeing what kinds of words are processed in each. Yet neuroscientists aren’t uniformly impressed.

  • invoked an old metaphor to explain why he isn’t convinced by the analysis: He compared it to establishing a theory of how weather works by pointing a video camera out the window for 7 hours.
  • Indeed, among neuroscientists, the new “comprehensive atlas” of the cerebral cortex is almost as controversial as a historical atlas of the Middle East. That’s because every word has a constellation of meanings and associations — and it’s hard for scientists to agree about how best to study them in the lab.
  • For this study, neuroscientist Jack Gallant and his team at the University of California, Berkeley played more than two hours’ worth of stories from the Moth Radio Hour for seven grad students and postdocs while measuring their cerebral blood flow using functional magnetic resonance imaging. Then, they linked the activity in some 50,000 pea-sized regions of the cortex to the “meaning” of the words being heard at that moment.
  • How, you might ask, did they establish the meaning of words? The neuroscientists pulled all the nouns and verbs from the podcasts. With a computer program, they then looked across millions of pages of text to see how often the words from the podcasts are used near 985 common words taken from Wikipedia’s List of 1,000 Basic Words. “Wolf,” for instance, would presumably be used more often in proximity to “dog” than to, say, “eggplant.” Using that data, the program assigned numbers that approximated the meaning of each individual word from the podcasts — and, with some fancy number crunching, they figured out what areas of the brain were activated when their research subjects heard words with certain meanings.
  • Everyone agrees that the research is innovative in its method. After all, linking up the meanings of thousands of words to the second-by-second brain activity in thousands of tiny brain regions is no mean feat. “That’s way more data than any human being can possibly think about,” said Gallant.
  • What they can’t agree on is what it means. “In this study, our goal was not to ask a specific question. Our goal was to map everything so that we can ask questions after that,” said Gallant. “One of the most frequent questions we get is, ‘What does it mean?’ If I gave you a globe, you wouldn’t ask what it means, you’d start using it for stuff. You can look for the smallest ocean or how long it will take to get to San Francisco.”
  • This “data-driven approach” still involves assumptions about how to break up language into different categories of meaning
  • “Of course it’s a very simplified version of how meaning is captured in our minds, but it seems to be a pretty good proxy,” she said.
  • hordes of unanswered questions: “We can map where your brain represents the meaning of a narrative text that is associated with family, but we don’t know why the brain is responding to family at that location. Is it the word ‘father’ itself? Is it your memories of your own father?

  • We found that a high mental load consistently diminished the originality and creativity of the response: Participants with seven digits to recall resorted to the most statistically common responses (e.g., white/black), whereas participants with two digits gave less typical, more varied pairings (e.g., white/cloud).

  • In another experiment, we found that longer response times were correlated with less diverse responses, ruling out the possibility that participants with low mental loads simply took more time to generate an interesting response.
  • it seems that with a high mental load, you need more time to generate even a conventional thought. These experiments suggest that the mind’s natural tendency is to explore and to favor novelty, but when occupied it looks for the most familiar and inevitably least interesting solution.
  • In general, there is a tension in our brains between exploration and exploitation. When we are exploratory, we attend to things with a wide scope, curious and desiring to learn. Other times, we rely on, or “exploit,” what we already know, leaning on our expectations, trusting the comfort of a predictable environment
  • Much of our lives are spent somewhere between those extremes. There are functional benefits to both modes: If we were not exploratory, we would never have ventured out of the caves; if we did not exploit the certainty of the familiar, we would have taken too many risks and gone extinct. But there needs to be a healthy balance
  • All these loads can consume mental capacity, leading to dull thought and anhedonia — a flattened ability to experience pleasure.
  • ancient meditative practice helps free the mind to have richer experiences of the present
  • your life leaves too much room for your mind to wander. As a result, only a small fraction of your mental capacity remains engaged in what is before it, and mind-wandering and ruminations become a tax on the quality of your life
  • Honing an ability to unburden the load on your mind, be it through meditation or some other practice, can bring with it a wonderfully magnified experience of the world — and, as our study suggests, of your own mind.

Eric A. Posner Reviews Jim Manzi's "Uncontrolled" | The New Republic - 0 views

  • Most urgent questions of public policy turn on empirical imponderables, and so policymakers fall back on ideological predispositions or muddle through. Is there a better way?
  • The gold standard for empirical research is the randomized field trial (RFT).
  • The RFT works better than most other types of empirical investigation. Most of us use anecdotes or common sense empiricism to make inferences about the future, but psychological biases interfere with the reliability of these methods
  • ...15 more annotations...
  • Serious empiricists frequently use regression analysis.
  • Regression analysis is inferior to RFT because of the difficulty of ruling out confounding factors (for example, that a gene jointly causes baldness and a preference for tight hats) and of establishing causation
  • RFT has its limitations as well. It is enormously expensive because you must (usually) pay a large number of people to participate in an experiment, though one can obtain a discount if one uses prisoners, especially those in a developing country. In addition, one cannot always generalize from RFTs.
  • academic research proceeds in fits and starts, using RFT when it can, but otherwise relying on regression analysis and similar tools, including qualitative case studies,
  • businesses also use RFT whenever they can. A business such as Wal-Mart, with thousands of stores, might try out some innovation like a new display in a random selection of stores, using the remaining stores as a control group
  • Manzi argues that the RFT—or more precisely, the overall approach to empirical investigation that the RFT exemplifies—provides a way of thinking about public policy. Thi
  • the universe is shaky even where, as in the case of physics, “hard science” plays the dominant role. The scientific method cannot establish truths; it can only falsify hypotheses. The hypotheses come from our daily experience, so even when science prunes away intuitions that fail the experimental method, we can never be sure that the theories that remain standing reflect the truth or just haven’t been subject to the right experiment. And even within its domain, the experimental method is not foolproof. When an experiment contradicts received wisdom, it is an open question whether the wisdom is wrong or the experiment was improperly performed.
  • The book is less interested in the RFT than in the limits of empirical knowledge. Given these limits, what attitude should we take toward government?
  • Much of scientific knowledge turns out to depend on norms of scientific behavior, good faith, convention, and other phenomena that in other contexts tend to provide an unreliable basis for knowledge.
  • Under this view of the world, one might be attracted to the cautious conservatism associated with Edmund Burke, the view that we should seek knowledge in traditional norms and customs, which have stood the test of time and presumably some sort of Darwinian competition—a human being is foolish, the species is wise. There are hints of this worldview in Manzi’s book, though he does not explicitly endorse it. He argues, for example, that we should approach social problems with a bias for the status quo; those who seek to change it carry the burden of persuasion. Once a problem is identified, we should try out our ideas on a small scale before implementing them across society
  • Pursuing the theme of federalism, Manzi argues that the federal government should institutionalize policy waivers, so states can opt out from national programs and pursue their own initiatives. A state should be allowed to opt out of federal penalties for drug crimes, for example.
  • It is one thing to say, as he does, that federalism is useful because we can learn as states experiment with different policies. But Manzi takes away much of the force of this observation when he observes, as he must, that the scale of many of our most urgent problems—security, the economy—is at the national level, so policymaking in response to these problems cannot be left to the states. He also worries about social cohesion, which must be maintained at a national level even while states busily experiment. Presumably, this implies national policy of some sort
  • Manzi’s commitment to federalism and his technocratic approach to policy, which relies so heavily on RFT, sit uneasily together. The RFT is a form of planning: the experimenter must design the RFT and then execute it by recruiting subjects, paying them, and measuring and controlling their behavior. By contrast, experimentation by states is not controlled: the critical element of the RFT—randomization—is absent.
  • The right way to go would be for the national government to conduct experiments by implementing policies in different states (or counties or other local units) by randomizing—that is, by ordering some states to be “treatment” states and other states to be “control” states,
  • Manzi’s reasoning reflects the top-down approach to social policy that he is otherwise skeptical of—although, to be sure, he is willing to subject his proposals to RFTs.

Beating History: Why Today's Rising Powers Can't Copy the West - Heather Horn - Interna... - 0 views

  • production in "all organic economies was set by the annual cycle of plant growth" -- it limits food, fuel, fiber, and building materials. Coal changed all that. By digging into the earth to get minerals instead of growing fuel on the earth, you get a vastly more efficient source of fuel and completely change the rules of the game. You've shifted from an organic economy, as he calls it, to an energy-rich economy. But the economic reprieve the fossil fuels offered could be nearing an end, as global supply becomes more competitive.
  • Historians still debate the nature and causes of the Industrial Revolution, but one thing they seem to agree on is that the it wasn't just industrial -- it was demographic and agricultural as well. Prior to the Industrial Revolution, populations all over the globe had non-negotiable checks on their growth: too many people and you get ecological crises and famines to push the number back down. In the 18th and 19th centuries, England managed to solve this problem, with tremendous leaps in population and urbanization as a result.

  • The challenge ahead for the BRICs, then, is to figure out how to maintain growth in a world where the vast new frontier opened up by the Industrial Revolution appears to be closing. The BRICs can play the West's game better than the West, both through technological innovation and population growth, but only for so long. The whole world has to figure out a way of dealing with energy and agriculture.
