NIH funds new All of Us Research Program genome center to test advanced sequencing tools – National Institutes of Health
Posted: October 24, 2019 at 10:46 am
News Release
Friday, October 18, 2019
HudsonAlpha awarded $7 million to expand national health dataset with uncharted genetic variants.
The All of Us Research Program has selected the HudsonAlpha Institute for Biotechnology, Huntsville, Alabama, to evaluate the use of leading-edge DNA sequencing technologies that could someday improve diagnosis and treatment of many diseases, both common and rare. The National Center for Advancing Translational Sciences (NCATS) is funding the project with $7 million over one year. All of Us and NCATS are parts of the National Institutes of Health.
All of Us will provide one of the worlds most robust platforms for precision medicine research, with a broad range of data to drive new discoveries, said Eric Dishman, All of Us director. Through this partnership with NCATS, well be able to offer approved researchers an even greater depth of genetic information than originally planned, making the resource even more valuable for them and the diverse communities we seek to help.
With this award, HudsonAlpha will use long-read whole genome sequencing technologies to generate genetic data on about 6,000 samples from participants of different backgrounds. Long-read sequencing analyzes DNA in larger segments than standard (short-read) sequencing technologies, exposing genetic variations that may otherwise go undetected. These variations include different types of alterations to the genetic structure, such as duplication, deletion or rearrangement of the building blocks that uniquely make up ones genome and set it apart from others. Everyone has thousands of these genetic variations, most with little known effect. However, researchers are learning more about how some genetic variants underlie certain health conditions or, conversely, increase disease resistance. Understanding the genetic underpinnings of health and disease will help researchers identify more targeted interventions in the future.
This project will allow researchers to better determine the value of long-read sequencing and its strengths and limitations in exploring more elusive parts of the genome. Combined with the 1 million whole genome sequences the program already plans to deliver over the next several years, this additional infusion of genetic information will provide the research community with the largest collection of genomic structural variation data and clinical data ever produced.
Because long-read sequencing can reveal genetic changes associated with rare diseases, this project is an opportunity to assess and potentially refine the technology for advancing research across the many diseases for which there is no treatment, said Christopher P. Austin, M.D., NCATS director. This project illustrates the power of data and technology to accelerate the translation of knowledge into improved health.
The HudsonAlpha team, led by Shawn Levy, Ph.D., brings significant experience in large-scale sequencing projects and in genetic studies on inherited disorders as well as complex conditions, including autism, diabetes, cancer, schizophrenia, degenerative neurological disease and amyotrophic lateral sclerosis(ALS).
We look forward to collaborating with the other All of Us genome centers and the rest of the consortium on this exciting effort, said Dr. Levy. Contributing long-read sequencing data to reveal additional structural variants will enable the scientific community to study human diversity on a tremendous scale.Appreciating the impacts of all types of genetic variation will further unravel the genetic, environmental and behavioral influences of health.
About theAll of UsResearch Program:Themissionof theAll of UsResearch Program is to accelerate health research and medical breakthroughs, enabling individualized prevention, treatment, and care for all of us. The programwill partner with one million or more people across the United States to build the most diverse biomedical data resource of its kind, to help researchers gain better insights into the biological, environmental, and behavioral factors that influence health. For more information, visitwww.JoinAllofUs.organdwww.allofus.nih.gov.
About the National Center for Advancing Translational Sciences (NCATS):NCATS conducts and supports research on the science and operation of translation the process by which interventions to improve health are developed and implemented to allow more treatments to get to more patients more quickly. For more information about how NCATS is improving health through smarter science, visithttps://ncats.nih.gov.
About the National Institutes of Health (NIH):NIH, the nation's medical research agency, includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical, and translational medical research, and is investigating the causes, treatments, and cures for both common and rare diseases.

Ambitious Initiative Brings Together Education Sector to "Map the EdTech Genome" – Yahoo Finance

Jefferson Education Exchange will create a framework to help school and district leaders understand why edtech products work in some contexts but not in others
WASHINGTON, Oct. 24, 2019 /PRNewswire/ --A new first-of-its-kind initiative, announced today, will create an evidence-based framework to help educators make better-informed decisions about what technology to use in their classrooms -- and how to implement it most effectively. Coordinated by the nonprofit Jefferson Education Exchange, the EdTech Genome Project will be overseen by a diverse group of educators, association leaders, researchers, and technology experts who represent the most influential voices in the national conversation on education technology.
(PRNewsfoto/Jefferson Education Exchange)
"Teachers are on the frontlines of decision-making about what technology to use in the classroom. Getting useful information to address the needs of students in our specific contexts helps us provide an equitable education," said Alexander Kmicikewycz, a teacher at Chicago Public Schools. "That's why teacher voice is so important in education research -- and why it's so exciting to be part of a research project that is bringing together stakeholders from across the education community to tackle such a significant challenge for educators."
The EdTech Genome Project is designed to address a critical collective action problem in education technology. Each year, educators and school administrators spend more than $13 billion on more than seven thousand technology tools and products. But because most purchasing decisions are chiefly influenced by word of mouth or internet searches, an estimated 85% of edtech tools are either a poor fit for a particular school, or are not implemented effectively. Yet there is no system through which educators can report the results of their implementations so that others may learn from them. As a result, billions of dollars continue to be wasted on tools and products that do not meaningfully improve student outcomes -- despite the best of intentions by all involved.
Backed by philanthropic and social impact organizations including Strada Education Network, the Chan Zuckerberg Initiative, and Carnegie Corporation of New York, the project will draw on extensive research and direct outreach with educators to identify up to ten contextual variables associated with edtech implementation success or failure. Once the stakeholders reach consensus on the list of variables, up to ten national working groups will be formed by bringing together the leading researchers and practitioners with deep experience in each variable. Each working group will then spend a year examining existing evidence and measurement instruments as each group works to reach consensus about how implementation factors such as "teacher agency," "initiative fatigue," "quality of professional development," and other technical and cultural factors can be quantified.
"If you want to improve your health, experts will ask you questions about your diet, current lifestyle, and fitness goals before recommending dietary changes and a fitness routine. For some people, a better choice may be water aerobics or yoga, while others may be ready to train for a marathon. But in education, we haven't applied research the same way," said Katrina Stevens, Director of Learning Sciences for the Chan Zuckerberg Initiative. "This is a critical first step towards creating a shared understanding of what technology works, where, and why."
Story continues
The EdTech Genome Project will be directed by a 30-member steering committee made up of leaders from education and research organizations including ISTE, the National Education Association, the American Federation of Teachers, Gallup, and the American Institutes for Research, as well as teachers and technology leaders from seven public school districts across the country.
"The way we use -- and misuse -- education technology has profound costs in not just economic, but equity, terms," said Bart Epstein, president and CEO of the Jefferson Education Exchange and a research associate professor at the University of Virginia Curry School of Education and Human Development. "This effort is about empowering educators and administrators by providing them access to the hard-earned experiences of their peers nationwide. Better understanding of what works where and why will enable them to fulfill the promise of technology to improve outcomes for all students."

How Automation and Machine Learning Help Explore the Dark Corners of the Genome – SynBioBeta
Posted: at 10:46 am
If you synthesized every variant of a 79-nucleotide long piece of DNA (479), their mass would be greater than the mass of the earth. If you did the same thing, but with 126 nucleotides, their mass would be greater than the observable universe. I first read about these hyper-astronomical numbers in a review by Ard Louis, Professor of Theoretical Physics at the University of Oxford.
Given that the E. coli genome is five million bases long, and the human genome is 600 times longer, how can engineers possibly know which precise modifications are best to overproduce some chemical, or which edits to make to stop the spread of a cancer? Nature has barely begun to explore this coding space, and we might be nave to think that we could do better.
In synthetic biology, the Design-Build-Test cycle is used to create organisms with desired properties. But, given the possible combinations of DNA sequences, it is nearly impossible to design the perfect DNA sequence for our desired application. A growing tide of computer-aided biology promises to accelerate this pipeline, using automated liquid handlers to Build (and in some cases Test), and feeding the resulting data into machine learning algorithms, which Design the next set of experiments.
Machine learning is just a set of algorithms that computers use to perform specific tasks without a set of direct instructions. Feed the computer lots of high-quality data, and it will tell you which experiment to perform next.
The Echo Liquid Handler developed by Labcyte, now part of Beckman Coulter Life Sciences, can help provide that data.
Moving liquid with sound waves, the Echo Liquid Handler is contact-free and capable of transferring 2.5 or 25 nanoliter increments precisely and accurately. For the synthetic biologist, you can combine a range of fluids from oligonucleotides, master mixes with enzymes to lysates for TX-TL expression without the need to calibrate the instrument, says John Lesnick, Senior Scientist at Beckman Coulter. The whole process is also remarkably fast, with the Echo transferring hundreds of droplets per second. This speed and precision enables scientists to test a far greater number of variants than would ever be possible by hand. The data collected here, once fed into machine learning algorithms, can be used to answer challenging questions, like:
Which guideRNA will best edit this gene?
Which promoter should I use to express this protein?
How can I modify this enzyme to maximize its catalytic turnover?
Many high-powered synthetic biology companies are already using this computer-aided approach to rewire biology at breakneck pace. Genome editing company Inscripta used machine learning algorithms to develop an all-in-one platform that can make hundreds of precise genome edits simultaneously in living cells. Zymergen is producing high-performance materials not found anywhere in nature by using machine learning to dictate which genetic modifications to make in an organism.
We are entering an era of computer-aided synthetic biology, where machines can run experiments, analyze the data, and design the next experiments. It may help us explore the darkest corners of genomes, and create incredible chemicals and products once inaccessible to nature.
Given the hyper-astronomical combinations that a DNA sequence can adopt, how can scientists find the best combination for their application?
Consider Inscriptas digital genome engineering platform, which was recently used to create a 200,000-edit library of an E. coli biosynthesis pathway. The system, which is an enclosed device that was formally announced at the SynBioBeta conference, uses CRISPR/Cas9 to make thousands of parallel edits at specific regions of the genome.
Richard Fox, Executive Director of Data Science at Inscripta.
The basic CRISPR technology has at least two key features, says Dr. Richard Fox, Executive Director of Data Science at Inscripta. One is the ability to cut a gene, then paste and repair So its probably not a stretch to imagine that were using data to derive the rules that optimize the editing processes.
To determine which guideRNAs are best for each edit, they leveraged machine learning. We generate a lot of data to figure out which designs work better than others, and part of improving our system performance is to use that data to empirically determine, along with statistics and machine learning, which guides are best for cutting, explains Fox.
But the utility of machine learning doesnt stop there. Inscripta is also using their gene editing platform to inform protein engineering and directed evolution, the same method that earned Frances Arnold, Professor at the California Institute of Technology, the 2018 Nobel Prize in Chemistry.
We spent a fair bit of time working in the field of protein engineering, especially through methods like directed evolution. Specifically, we generated genotype and phenotype data around enzymes and other proteins, says Fox, referring to how a DNA sequence encoding a protein can impact the observable characteristics of an organism (i.e., its phenotype).
Inscripta, for example, can make many different edits in the DNA sequence encoding an enzyme, and then run experiments to measure the phenotypes that result. If the enzyme is responsible for producing a bright pigment, then certain edits will cause it to produce more or less of that pigment. By feeding that information into machine learning pipelines, the algorithm can predict which edits will maximize the desired phenotype.
Forty minutes northwest of Inscripta, in Emeryville, California, Zymergen is using similar strategies to engineer the future of molecules and materials.
Biology is an incredibly powerful, multi-purpose tool, and it can be aimed at any number of different endpoints, says Aaron Kimball, CTO of Zymergen.
Within a 310,000 square-foot space in Emeryville, Zymergen is using engineered organisms to produce a slew of chemicals and materials. Though inspired by nature, many of the materials they create are not found anywhere else on earth. Just like Inscripta, their engineering process requires the exploration of hyper-astronomical spaces to find the DNA combinations that work best to produce a desired compound.
To build the strains that we use for full-scale fermentation, we use lab automation systems. Theres a loop that we usedesign, build, test and analyze. In the design phase, we design many genetic edits that we believe will be beneficial, then we physically make those edits in our strains, and then we test them for different responses, says Kimball.
Once liquid handlers are used to build the strains, the resulting data informs the next round of experiments, says Kimball. In the learning phase, we update any models that we made and feed that information into the next round of designso the build phase and the test phase are, essentially, entirely performed on lab automation systems so that we can perform this work at scale.
In Zymergens case, the objective is to engineer organisms that can produce custom designed materials and chemicals at scale. Often, seemingly innocuous edits in a single gene can lead to superior strains with higher production capabilities. But finding which edits to make requires a constant dialogue between data and algorithms.
We have one of the largest libraries of DNA available in the worldas well as an electronic database that we can search. So we can use machine learning algorithms to search that database for homologs to genes that might be beneficial replacements over the genes that are naturally encoded in an organism, says Kimball. We might also [use machine learning to] search more heavily into the dark matter of the genome, the genes of no known functionand then combine beneficial edits or mutations.
Despite being founded in 2013, Zymergen has already used this automation-meets-machine-learning approach with remarkable success. Although the company hasnt revealed their customers, co-founder and CEO Joshua Hoffman has previously stated that their clients have sold half a billion dollars worth of products made with our bugs in the last couple of years.
Zymergen CEO Joshua Hoffman
Synthetic biologists want to create a biological future that moves our civilization away from petrochemicals, demonstrates the promise of renewables, and produces high quality products for less. Considering the hyper-astronomical possibilities of genetic sequences, it is clear that humans are poorly equipped to test this vast space.
But maybe high-throughput liquid handlers, like the Echo, coupled with machine learning algorithms, can help us learn from biology, sift through the dark corners of genomes, and continue advancing this biologized industrial revolution.

1 Billion Years of Evolution Illuminated by Genetic Sequencing of 1,100 Plants – SciTechDaily
Posted: at 10:46 am

Plants are evolutionary champions, dominating Earths ecosystems for more than a billion years and making the planet habitable for countless other life forms, including us. Now, scientists have completed a nine-year genetic quest to shine a light on the long, complex history of land plants and green algae, revealing the plot twists and furious pace of the rise of this super group of organisms.
The project, known as the One Thousand Plant Transcriptomes Initiative (1KP), brought together nearly 200 plant biologists to sequence and analyze genes from more than 1,100 plant species spanning the green tree of life. A summary of the teams findings published on October 23, 2019, in Nature.
In the tree of life, everything is interrelated, said Gane Ka-Shu Wong, lead investigator of 1KP and professor in the University of Albertas department of biological sciences. And if we want to understand how the tree of life works, we need to examine the relationships between species. Thats where genetic sequencing comes in.
Much of plant research has focused on crops and a few model species, obscuring the evolutionary backstory of a clade that is nearly half a million species strong.
To get a birds-eye view of plant evolution, the 1KP team sequenced transcriptomes the set of genes that is actively expressed to illuminate the genetic underpinnings of green algae, mosses, ferns, conifers, flowering plants and all other lineages of green plants.
One hallmark of plant evolution is the frequency of genome duplication. Flowering plants are renowned for making multiple copies of their genome, which may contribute to the evolution of new gene functions. The 1KP project uncovered previously unknown duplication events in this group. Credit: Kristen Grace/Florida Museum
This gives a much broader perspective than what you could get by just looking at crops, which are all concentrated in one little part of the evolutionary tree, said study co-author Pamela Soltis, University of Florida distinguished professor and Florida Museum of Natural History curator. By having this bigger picture, you can understand how changes occurred in the genome, which then allows you to investigate changes in physical characteristics, chemistry or any other feature youre interested in.
One challenge was the projects sheer size, said study co-author Douglas Soltis, UF distinguished professor, and Florida Museum curator.
To look at that many genomes is unparalleled, he said. Its not a jump in technology as much as a jump in scale.
Sequencing transcriptomes requires freshly collected tissues, which is how Soltis found himself trekking through Gainesvilles greenery with containers of liquid nitrogen. Back at the laboratory, a team extracted genetic material from the frozen plant clippings and shipped the extractions to China for sequencing. All over the world, their colleagues followed suit.
Analyzing the sequences also required a reworking of existing software, which wasnt designed to handle such an unprecedented volume of genetic data, and without funding for the analysis, the researchers chipped away at the data as they had spare time.
But the labor was worth it, Pamela Soltis said.
The plant community got more than 1,000 sets of sequences, said Soltis, who also directs the UF Biodiversity Institute. Who could argue with that? All these branches of the plant tree of life have been filled in.
One hallmark of plant evolution and a feature rarely seen in animals is the frequency of genome duplication. Over and over again, lineages doubled, tripled or even quadrupled their entire set of genes, resulting in massive genome sizes. While the purpose of whole genome duplication is still unclear, scientists suspect that it may drive evolutionary innovation: If you have two copies of genes, one copy can gradually evolve a new function.
Addressing the frequency of whole genome duplication in plants was one of 1KPs goals, Douglas Soltis said. While flowering plants and ferns were already famous for genome duplication, Soltis said 1KP uncovered a number of previously unknown duplication events in these groups, as well as in the gymnosperms, the group of plants that includes conifers.
Other plant lineages took a different route, expanding certain gene families rather than copying their entire genome. This, too, is thought to provide new avenues for evolutionary development, and not surprisingly, the research team uncovered a major expansion of genes just before the appearance of vascular plants, land plants with xylem and phloem special cells for transporting water and nutrients.
But Douglas Soltis said gene expansions did not always correspond to major plant evolutionary milestones.
Theres not much of an expansion before seed plants appear or for flowering plants, he said. In fact, flowering plants actually shrank certain gene families, which may be a sign that they just co-opted existing genes for new functions.
Another surprise finding was that mosses, liverworts and hornworts form a single related group, confirming a centuries-old hypothesis that had been reversed in recent decades.
Wed done a partial analysis in 2014 that suggested these plants were close relatives, but a lot of people didnt believe it. These results underscore those findings, Pamela Soltis said. Its going to rock the moss world.
While the project refines our understanding of plant evolution and relationships between lineages, these data are also invaluable tools for advancing crop science, medicine, and other fields, the researchers said.
Identifying genes that have been duplicated in flowering plants could help scientists better understand their function, which could lead to crop improvements, Pamela Soltis said.
And because many plants have medicinal benefits, the genetic data offered by the 1KP project could lead to new discoveries that improve human health.
We focused on getting a lot of wild samples collected from plant lineages known to have important chemistry in hopes that people could mine this material for new compounds, Douglas Soltis said.
The sequences generated by the 1KP team are publicly accessible through the CyVerse Data Commons.
Probably hundreds of papers have used the data in ways we dont even know about, Pamela Soltis said. That is a super cool aspect of this study.
But the 1KP team has little time to celebrate its achievement. The next goal? Sequencing 10,000 genomes.

Gene Sequences Shed Light on Over One Billion Years of Green Plant Evolution – Technology Networks
Posted: at 10:46 am
Gene sequences for more than 1100 plant species have been released by an international consortium of nearly 200 plant scientists who were involved in a nine-year research project,One Thousand Plant Transcriptomes Initiative(1KP), that examined the diversification of plant species, genes and genomes across the more than one-billion-year history of green plants dating back to the ancestors of flowering plants and green algae.
Their findings, One Thousand Plant Transcriptomes and Phylogenomics of Green Plants, published today inNature, (doi: 10.1038/s41586-019-1693-2) reveal the timing of whole genome duplications and the origins, expansions and contractions of gene families contributing to fundamental genetic innovations enabling the evolution of green algae, mosses, ferns, conifer trees, flowering plants and all other green plant lineages. The history of how and when plants secured the ability to grow tall, and make seeds, flowers and fruits provides a framework for understanding plant diversity around the planet including annual crops and forest tree species. Sequences, sequence alignments and tree data are available through theCyVerse Data Commons.
Plants have evolved to produce numerous useful chemicals. This study provides insight into that evolutionary process, saidToni Kutchan, Ph.D., vice president for Research and Oliver M. Langenberg Distinguished Investigator,Donald Danforth Plant Science Center. Megan Augustin, research associate, Alex Harkess, Ph.D., postdoctoral associate and Michael McKain, Ph.D., former postdoctoral associate at the Danforth Center also contributed to the research.
Over 100 taxonomic specialists contributed material from field and living collections that include theCentral Collection of Algal Cultures,Royal Botanic Gardens, Kew,Royal Botanic Garden Edinburgh,Atlanta Botanical Garden,New York Botanical Garden,Fairylake Botanical Garden, Shenzhen,TheFlorida Museum of Natural History,Duke University,University of British Columbia Botanical GardenandThe University of Alberta. By sequencing and analyzing genes from a broad sampling of plant species, researchers are better able to reconstruct gene content in the ancestors of all crops and model plant species, and gain a more complete picture of the gene and genome duplications that enabled evolutionary innovations.
In the tree of life, everything is interrelated, saidGane Ka-Shu Wong, lead investigator and professor in the University of AlbertasDepartment of Biological Sciences. Our inferred relationships among living plant species inform us that over the billion years since an ancestral green algal species split into two separate evolutionary lineages, one including flowering plants, land plants and related algal groups and the other comprising a diverse array of green algae, plant evolution has been punctuated with innovations and periods of rapid diversification saidJames Leebens-Mack, professor of plant biology in theUniversity of Georgia Franklin College of Arts and Sciencesand co-corresponding author on the study.
The massive scope of the project demanded development and refinement of new computational tools for sequence assembly and phylogenetic analysis. New algorithms were developed for inferring evolutionary relationships from hundreds of gene sequences for over one thousand species, addressing substantial heterogeneity in evolutionary histories across the genomes.
The Somekh Family Foundation, Government of Alberta and a sequencing commitment from BGI in Shenzhen, China, were secured by Wong to launch 1KP. Once the project was operational, additional resources came from other ongoing projects, including iPlant (nowCyVerse) funded by theU.S. National Science Foundation.

Zuckerberg on Chinese censorship: Is that the internet we want? – TechCrunch
Posted: October 23, 2019 at 9:46 am
China is exporting its social values, political ads are an important part of free expression and the definition of dangerous speech must be kept in check, Facebooks CEO Mark Zuckerberg argued today in a speech at Georgetown University.
He criticized how American companies that do business with China were becoming influenced by the countrys values. While our services like WhatsApp are used by protestors and activists everywhere due to strong encryption and privacy practices, on TikTok, the Chinese app growing quickly around the world, mentions of these same protests are censored, even here in the U.S.! Zuckerberg said. Is that the Internet that we want?
Because Facebook couldnt come to an agreement with Chinese censors and thereby doesnt operate in the nation, Now, we have more freedom to speak out and stand up for the values that we believe in and fight for free expression around the world. While he didnt mention Apple, the NBA and Blizzard, which are amidst scandals about cowing to Chinese policy, the shade thrown at them was clear.
Zuckerberg spoke today for 40 minutes at Georgetown University and then did a Q&A to share his thoughts on speech and how we might address the challenges that more voice and the internet introduce, and the major threats to free expression around the world. He discussed how We want the progress of free expression without the tension, leading people to advocate for pulling back on free expression. Where do you draw the line?
Zuckerberg says that Facebook now has 35,000 people working on security, and the companys security budget is higher now than the whole revenue of the company when it IPOd, which was $5 billion in 2012. Facebook removes or downranks content that is objectively dangerous. Still, he says that he doesnt want to let the definition of what is dangerous expand beyond whats absolutely necessary.
Coining a new phrase, Zuckerberg noted that People having the power to express themselves at scale is a new kind of force in the world a Fifth Estate alongside the other power structures of society.
On allowing political ads on Facebook even if they carry misinformation, Zuckerberg argues that political ads can be an important part of voice, especially for local candidates, up and coming challengers and advocacy groups that the media might not otherwise cover. That way they can get their voice into the debate. While that may be true, the same system allows whichever group or candidate has the most funding to dominate the narrative.
I recently argued that Facebook should drop all political ads until regulation to prevent their use to spread misinformation was passed. President Trump is spending more than many of his Democratic party rivals combined while using lies about them planning to remove the second amendment to raise money.
Still, Zuckerberg argues, Banning political ads favors incumbents and whoever the media chooses to cover. He did not address who spends the most or how Facebook could still offer free expression of candidates to their own followers even if it banned political ads. He essentially drew no distinction between freedom of speech and freedom of reach aka paid amplification through ads. Instagram CEO Adam Mosseri echoed this sentiment, equating ads and speech, tweeting I believe that people deserve to hear what politicians are saying and make up their own minds. After some discussion, though, Mosseri admitted I often wish we could ban political ads, but said it would be complex to define what did and didnt qualify as one.
Relying on favoring incumbents argument ignores how President Trump has spent $4.9 million on Facebook ads this year compared to $9.6 million spent by the 23 Democratic candidates combined, and that Trump had outspent them all put together as of March. Banning political ads wouldnt prevent candidates from saying what they want and being judged, but it would stop richer candidates speech from having more weight.
Overall, Zuckerberg sounded more passionate and empathetic than in his recent testimonies on Capitol Hill. He seemed to take on some of the cadence and tone of former President Barack Obama, pitching up his voice to stress the urgency of challenges facing democracy. However, the speech format allowed Zuckerberg to avoid immediate pushback on his points, such as why political advertising favors challengers if its incumbents with the most money to spend. Zuckerberg did hold a Q&A after his speech, but the stream of that wasnt broadcast from his Page like the prepared remarks, and he mostly reiterated points from the speech.
Zuckerberg drove home one important theme threaded throughout the talk, though. He attempted to link the idea of U.S. companies potentially policing free expression to protect safety and elections with how China censors speech. And while other companies like the NBA and Blizzard that do significant business with the country try to downplay its influence, Zuckerberg spoke up about how the tentacles of Chinas values are choking off speech far beyond its borders.

Report On Global Social Media Censorship Shows Russia, India, And Turkey Are Still Leading The Censor Pack – Techdirt
Posted: at 9:46 am
from the and-all-these-US-companies-are-giving-them-a-boost dept
Millions of people around the globe are using blogging services and social media platforms created by US companies to communicate with each other. Unfortunately, these US companies have been helping censorial governments shut their citizens up by complying with a large variety of content removal requests.
While it is generally a best practice to follow local laws when offering services in foreign countries, it's always disappointing when US companies respect laws that have been created solely for the purpose of stifling dissent, silencing critics, and putting marginalized people at the risk of even greater harm.
Paul Bischoff of Comparitech has compiled information from a number of companies' transparency reports to produce an easily-readable snapshot of worldwide censorship as enabled by US tech companies. And the countries you'd expect to be demanding the censorship of the most content are the ones you'll see taking top spots at various platforms. Russia, Turkey, and India all top the charts, both in the number of demands made and the actual amount of memory-holed content.
Russia must be home to one of the last large Blogger userbases, considering how often the country targets this platform. Russia alone accounted for 53% of the 115,000 removal requests received by Google, which also covers search engine listings and YouTube. Russia's takedown demands have been steadily escalating over the past half-decade, jumping from 2,761 in 2015 to 19,192 in the first half of 2018 alone. Most of Russia's requests are supposedly "national security" related, but that still leaves plenty to spread around to cover other things the government disapproves of, like nudity, drug abuse, and defamation.
Turkey comes in at a very distant second. It too likes to claim stuff is either defamation or a threat to national security, but it prefers to perform its vicarious censorship on a different social media platform: Twitter.
Turkey jumps into the top spot here, accounting for 55.23 percent of the overall number of requests (54,652). Russia is a distant second with 21.17 percent of the overall number.
But Russia is gaining ground
[T]he largest number of content removal requests came last year with 23,464 (an 84% increase on the previous year). [...]Russia and Turkey... made up 21.25 and 59.67 percent of the requests in 2018, respectively.
Yes, Twitter is Turkey's playground. The easily-offended head of state (and all of his easily-offended officials) love to use content removal requests to silence critics and bury unflattering coverage. Unfortunately, Twitter has been all too helpful when it comes to Turkey oppressing its citizens via third parties. Sure, much of the blocking only affects Turkey, but that's where dissenting views are needed the most.
Bischoff's report is worth reading in full. It breaks down the raw data of transparency reports into easily-digestible chunks that show which platforms which countries censor most, as well as the type of complaints these countries are sending most often.
You'll also see why one of the biggest censors in the world barely shows up in these reports. China doesn't need third parties' help to control what its citizens see online. It begins this censorship at home by blocking content across multiple platforms (and, often, the platforms themselves), some of which are homegrown services far more popular with Chinese users than their American equivalents. A lack of data doesn't mean China is taking a hands-off approach to content moderation. It simply means the Chinese government rarely has to put its hands on anything outside the country to achieve its aims.
One of the more minor players in the global takedown playground is Wikimedia. Outside of the occasional DMCA takedown request, Wikimedia rarely gets hassled by anyone, much less world governments. But the requests it does get are far weirder than the run-of-the-mill censor-by-proxy requests delivered to social media platforms. Wikimedia is one of the few American entities that has told the Turkish government to beat it when Turkey asked for negative (but apparently factual) content to be removed. It also had to explain to members of an unnamed political party how Wikipedia -- and the First Amendment -- actually work.
A lawyer reached out to us on behalf of a lesser-known North American political party that was unhappy with edits to English Wikipedia articles about the party and one of its leaders. Her clients apparently wanted previous, more promotional versions of the articles restored in place of the later versions. To better engage in discussions with the community, we encouraged them to familiarize themselves with Wikipedias recommendations on style and tone and the policy restricting use of promotional language. We also advised that one of the best ways to resolve their concerns is to engage with the community directly.
And it has only removed one piece of content ever that wasn't the result of a valid DMCA takedown request:
According to Wikimedia, a blogger visiting Burma/Myanmar posted a redacted photo of his visa on his website. Somehow, a version of his visa picture without his personal information removed ended up on an English Wikipedia article concerning the countrys visa policy.
He wrote to us, asking to remove the photo, wrote Wikimedia. Given the nature of the information and the circumstances of how it was exposed, we took the image down.
Tech advances have accelerated the pace of global censorship. When you're dealing with the world's greatest communication tool -- the internet -- you kind of have to take the good with the bad. Geoblocking content to stay in the good graces of foreign governments may seem like the "lesser of several evils" approach, but even if it's the approach that will result in the least amount of collateral damage, it's still something that encourages authoritarians to continue being authoritarian.

Blizzard Gaming Boycott Is The Tip Of The Chinese Censorship Iceberg – The Federalist
Posted: at 9:46 am
If youve somehow managed to browse the internet without hearing about the Blizzard debacle, let me catch you up: Blizzard Entertainment is a gaming company that runs Hearthstone, an online card game with competitive tournaments. A Hong Kong-based player named Ng Wai Chung (alias Blitzchung) used a pro-democracy slogan during a post-match interview that was being live-streamed, and Blizzard suspended Blitzchung for six months, withholding his prize money to appease the Chinese government.
It may sound like a small incident, but it created a huge online backlash culminating in a boycott, which led to Blizzard reducing Blitzchungs suspension and returning his prize money. A large-scale boycott may seem like a disproportionate response, and, if this event had occurred in isolation, it would be disproportionate.
But Blitzchungs ban did not occur in isolation. This is just one of many recent cases in which other countries have changed their policies to appease the Chinese government, and these policy changes have affected people outside China. In July of last year, several American airline companies changed their websites to make it look as if Taiwan were not a sovereign country, at the request of the Chinese Communist Party (CCP).
The NBA recently groveled to the CCP because a team manager criticized the Chinese government on Twitter. Apple recently pulled an app from its app store that helps Hong Kong protesters track the police, although this move was recently reversed. Over and over again, CCP censorship has insinuated itself into global business by leveraging the lucrative Chinese market. The Blizzard boycott was just the tip of the censorship iceberg.
We can set up the problem like this: The Chinese government will never budge on censorship, but Western consumers will raise hell when they feel they are being subjected to it and this, in turn, has been at least partially effective, as is evident in the cases of Blizzard and Apple. So far, the trend has been Western companies walking a very thin line between losing access to the Chinese market and losing their customer base everywhere else.
This cant last forever. The Chinese government will not be content with repeated incidents of this kind, and Western consumers will prove allergic to CCP censorship. Moreover, the U.S. government is showing itself increasingly willing to challenge China economically. The U.S.-China trade war has exacerbated all of this a great degree. Something has to give.
A full geopolitical examination of the U.S.-China relationship is far, far beyond the scope of this article, but suffice it to say, the current state of economic conflict is not entirely due to the Trump administration. This confrontation was a long time coming, and the reasons for it go far deeper than Trump.
So when you hear a dispatch from the White House saying America is reaching the first phases of a trade deal with China, dont be fooled this is far from over. The United States, even if it hammers out a deal with China, will still make policy changes to decouple its economy from Chinas. This conflict is far more profound than the election of a hotheaded American president, and it will continue long after hes out of office.
There are three factors: the stubbornness of the Chinese government, the stubbornness of Western consumers, and the trade war and deeper economic conflict between the American and Chinese governments. Of those three factors, something has to give. Either Western consumers must accept a certain amount of CCP censorship, the CCP must cease its efforts to promote its own interest via censorship (and other underhanded means), or economies that do not wish to bend the knee to the CCP must decouple themselves from China. Ill discuss each in turn.
Keep in mind that these are extreme outcomes. Various mixtures of each are possible. Each one is a kind of limit scenario, a pure outcome relating to one of the three factors giving way. I do not expect any of these three to pan out exactly as described, but this is useful for illustrative purposes.
First possibility: With the rise of China, commonly prophesied among economists and geopolitical pundits, it may be that Chinas economic power becomes so overwhelming that foreign companies will be unable to resist CCP censorship. If the Chinese economy is so dominating that no multinational can compete without access to it, then all multinationals are effectively subject to China.
The world would live under de facto Chinese censorship. You and I and other private individuals may be able to criticize the Chinese government on our own time, but no person who is remotely prominent would dare to say a word against the CCP, since doing so could easily result in the loss of ones career.
This may sound like doom-mongering, and I will concede that it is unlikely, but its also not impossible. This is what happens if the first factor, Western stubbornness, fails.
Second possibility: With China suffering from the trade war and the United States in a hurry to decouple itself from the Chinese economy, it may turn out that the foretold pax sinica was a mirage all along. If thats true, then Chinas various economic problems, such as its (most likely permanent) status as a net importer of food, the demographic time-bomb of its aging population, and civil unrest such as that seen in Hong Kong, will all come home to roost just as the West begins to crank up the heat.
While the shrinking of the Chinese economy will cause economic problems worldwide, it would have at least one positive effect: The CCP would no longer have a big enough bargaining chip to enforce its censorship on foreign countries. Perhaps it would be possible to convince the CCP to do this without removing Chinas economic clout, but Im pessimistic about that possibility and cannot see the Chinese government removing its censorship. This is what happens if the second factor, Chinese stubbornness, fails.
Third possibility: If the trade war ends in long-term decoupling without terminal economic problems for either side, then a simple economic decoupling may defang the CCPs influence on foreign companies without forcing it to drop its censorship. This seems unlikely, given the interconnectivity of the world in the information age. On the other hand, much of that exchange of information sits on an underlying economic entanglement, which, in this scenario, would drop out.
As I said before, these are three extreme scenarios, and in the short to medium term, none can manifest purely without admixture of the others. In the long term, however, I do think the overall geopolitical situation will be strongly characterized by one of these three. The only question is, which one?

The night the censors drove old ‘Dixie’ down – Washington Examiner
Posted: at 9:46 am
Winston-Salem, North Carolina, operates on a more liberal compass heading than much of the South. But it carries the unfortunate distinction of having hosted the Dixie Classic Fair since 1956.
The word Dixie, NPR reported, offends enough locals (and one assumes outsiders) that the city is censoring it out of existence.
Some local skeptics questioned whether the name Dixie Classic Fair should be stripped from history, puzzled that next to go might be Dixie Cups. For good measure, lets throw in Dixieland, Dixie Mart, Winn-Dixie, and the Dixie Chicks. These all may somehow offend, and the absurdity of changing them won't be enough to pause hit the "pause" button on the non-stop movie of censorship.
Censorship has long been the first refuge of scoundrels, and history isnt always forgiving of their cause. Stalin erased Nikolai Yezhov from a now-famous official propaganda photo, which only served to keep the functionarys name alive well beyond his historical due. The salting of Carthage after the Third Punic War one of Romes more memorable mop-up operations might be the only thing keeping Carthages name alive two millennia later. And who can forget about Galileo? His name lives on, whereas that of Pope Urban VIII, who tried to silence him, is almost forgotten.
Taking offense to words and symbols is as natural as breathing. Censoring them out of existence is operating on a far grander scale. When I was growing up in California, a group of atheists decided that places with Christian saints names had to go, ostensibly for violating the separation of church and state. But this was really because, as atheists, they just hated Christianity.
Think of the audacity: the logistics of changing every offending name, from San Anselmo to San Francisco to Los Angeles, and every Zion in between (thats every persons drivers license, every official document, every newspaper masthead, etc.). It would have bankrupted many of these municipalities and all just for the fun of it. The coup failed, but not without extravagant legal fees, paid mostly by the citizenry. Every time I pass the highway sign at Grass Valley that reads, San Francisco, 143 Miles my heart sings, not simply because Im going back to the city of my birth, but because, despite a tiny few ill-intentioned and censorious atheists, it is still San Francisco.
Most recently, and coincidentally, was the San Francisco Board of Educations decision (these are educators mind you) to censor an anti-racist mural in a local high school. The Life of Washington, painted in 1936 by an avowed left-wing agitator to depict the evils of slavery and exploitation in the founding of the nation, is ironically the very thing todays leftists would trip over themselves to erect in public. Its depiction of slaves and Native Americans could not be more poignant.
But because the very liberal Board of Education has become hyper-sensitive to the supposed hyper-sensitivity of students, this piece of history had to go. This time, the censors won, but not without embarrassment since some in the media were actually watching and wondering, This is What Educators Do?
By the way, student attitudes towards the mural before, during, and since the controversy remained decidedly apathetic. So much for the little dears' sensitivity.
Meanwhile, as the grievance industry pursues its metaphorical March to the Sea with all of Sherman's subtlety, its worth revisiting someone whose legacy has a dog in this fight: Rev. Martin Luther King, Jr. He may not have known he belongs in the censorship battles, but he does.
King, deeply a son of the South, was unequivocal about the pasts eventual reckoning. The arc of history is long, but it bends towards justice, he said, and liberals like to quote him on that. But one may ask if, for King, that means all of history or just some selections from a drop-down menu that suits the tenor of the current era.
A basic reading of the man offers a simple answer. For King, the pastor and prophet, the linearity of Christianity promises redemption and salvation, but one must live within human history to get there. The problem of this history is both our fate and our calling. It is not a trifle.
How dare you invoke King, some will say, and not without good intention, though certainly fueled by emotion and mistrust. Those who defend censorship in the name of soothing bruised sensitivities would do well to recognize that King himself was as much a maker of history as he was its victim. The glory of King cannot exist without the shame of the past. Yin and yang are inseparable. Destroy one, you destroy the other.
Two quotes in a teachable moment are always better than one. George Santayanas all-purpose cheer for history Those who do not remember the past are condemned to repeat it itself always bears repeating. Would King subscribe to an updating of his own words? "The arc of history is long, but it bends towardscensorship?"
