Google Trained a Trillion-Parameter AI Language Model
An anonymous reader quotes a report from VentureBeat:
Google researchers developed and benchmarked techniques they claim enabled them to train a language model containing more than a trillion parameters. They say their 1.6-trillion-parameter model, which appears to be the largest of its size to date, achieved an up to 4 times speedup over the previously largest Google-developed language model (T5-XXL). As the researchers note in a paper detailing their work, large-scale training is an effective path toward powerful models. Simple architectures, backed by large datasets and parameter counts, surpass far more complicated algorithms. But effective, large-scale training is extremely computationally intensive. That's why the researchers pursued what they call the Switch Transformer, a "sparsely activated" technique that uses only a subset of a model's weights, or the parameters that transform input data within the model.
In an experiment, the researchers pretrained several different Switch Transformer models using 32 TPU cores on the Colossal Clean Crawled Corpus, a 750GB-sized dataset of text scraped from Reddit, Wikipedia, and other web sources. They tasked the models with predicting missing words in passages where 15% of the words had been masked out, as well as other challenges, like retrieving text to answer a list of increasingly difficult questions. The researchers claim their 1.6-trillion-parameter model with 2,048 experts (Switch-C) exhibited "no training instability at all," in contrast to a smaller model (Switch-XXL) containing 395 billion parameters and 64 experts. However, on one benchmark -- the Sanford Question Answering Dataset (SQuAD) -- Switch-C scored lower (87.7) versus Switch-XXL (89.6), which the researchers attribute to the opaque relationship between fine-tuning quality, computational requirements, and the number of parameters.
This being the case, the Switch Transformer led to gains in a number of downstream tasks. For example, it enabled an over 7 times pretraining speedup while using the same amount of computational resources, according to the researchers, who demonstrated that the large sparse models could be used to create smaller, dense models fine-tuned on tasks with 30% of the quality gains of the larger model. In one test where a Switch Transformer model was trained to translate between over 100 different languages, the researchers observed "a universal improvement" across 101 languages, with 91% of the languages benefitting from an over 4 times speedup compared with a baseline model. "Though this work has focused on extremely large models, we also find that models with as few as two experts improve performance while easily fitting within memory constraints of commonly available GPUs or TPUs," the researchers wrote in the paper. "We cannot fully preserve the model quality, but compression rates of 10 to 100 times are achievable by distilling our sparse models into dense models while achieving ~30% of the quality gain of the expert model."
AT&T Kills Off the Failed TV Service Formerly Known As DirecTV Now
killing off the online-video service formerly known as DirecTV Now and introducing a no-contract option for the newer online service that replaced it. Ars Technica reports:
AT&T unveiled DirecTV Now late in 2016, the year after AT&T bought the DirecTV satellite company. Prices originally started at $35 a month for the live-TV online service, and it had signed up 1.86 million subscribers by Q3 2018. But customers quickly fled as AT&T repeatedly raised prices and cut down on the use of promotional deals, leaving the service with just 683,000 subscribers at the end of Q3 2020. In 2019, AT&T changed the name from DirecTV Now to AT&T TV Now, creating confusion among customers and its own employees because the company simultaneously unveiled another online streaming service called AT&T TV.
AT&T TV was pitched as a more robust replacement for satellite TV, and it even mimicked cable and satellite by imposing contracts, hidden fees, and a big second-year price hike. Going forward, AT&T TV Now will no longer be offered to new customers, and AT&T TV will be the flagship for AT&T's live-TV streaming business. "AT&T TV Now has merged with AT&T TV," the service's website says in an update flagged in a news article by TV Answer Man yesterday. For existing users, "AT&T TV Now customers' service and plans remain in effect" without any changes, an AT&T spokesperson told Ars. "We have no other price changes to announce at this time."
The Linux Foundation Now Offers a Suite of Open-Source Management Classes
The Linux Foundation has new courses to
help you manage open-source projects and technical staff within your organization. Steven J. Vaughan-Nichols writes via ZDNet:
Previously, if you want to know how to run open-source well in your company, you had to work with OASIS Open or the TODO Group. Both are non-profit organizations supporting best open source and open standards practices. But, to work with either group, effectively, you already had to know a lot about open source. [...] This 7-module course series is designed to help executives, managers, software developers, and engineers understand the basic concepts for building effective open-source practices. It's also helpful to those in the C suite who want to set up effective open-source program management, including how to create an Open Source Program Office (OSPO).
The program builds on the accumulated wisdom of many previous training modules on open-source best practices while adding fresh and updated content to explain all of the critical elements of working effectively with open source in enterprises. The courses are designed to be self-paced, and reasonably high-level, but with enough detail to get new open-source practitioners up and running quickly. Guy Martin, OASIS Open's executive director, developed these courses. Martin knows his way around open source. He has a unique blend of over 25 years' experience both as a software engineer and open-source strategist. Marin has helped build open-source programs at Red Hat, Samsung, and Autodesk. He was also instrumental in founding the Academy Software Foundation, the Open Connectivity Foundation, and has contributed to TODO Group's best practices and learning guides. The "
Open Source Management & Strategy program" costs $499 and is available to begin immediately. A certificate is awarded upon completion.
FTC Settlement With Ever Orders Data and AIs Deleted After Facial Recognition Pivot
The maker of a defunct cloud photo storage app that pivoted to selling facial recognition services has been
ordered to delete user data and any algorithms trained on it, under the terms of an
FTC settlement. TechCrunch reports:
The regulator investigated complaints the Ever app -- which gained earlier notoriety for using dark patterns to spam users' contacts -- had applied facial recognition to users' photographs without properly informing them what it was doing with their selfies. Under the proposed settlement, Ever must delete photos and videos of users who deactivated their accounts and also delete all face embeddings (i.e. data related to facial features which can be used for facial recognition purposes) that it derived from photos of users who did not give express consent to such a use. Moreover, it must delete any facial recognition models or algorithms developed with users' photos or videos.
This full suite of deletion requirements -- not just data but anything derived from it and trained off of it -- is causing great excitement in legal and tech policy circles, with experts suggesting it could have implications for other facial recognition software trained on data that wasn't lawfully processed. Or, to put it another way, tech giants that surreptitiously harvest data to train AIs could find their algorithms in hot water with the US regulator.
ECB's Christine Lagarde Blasts Bitcoin's Role In Facilitating Money Laundering
An anonymous reader quotes a report from Bloomberg:
European Central Bank President Christine Lagarde took aim at Bitcoin's role in facilitating criminal activity, saying the cryptocurrency has been enabling "funny business." "For those who had assumed that it might turn into a currency -- terribly sorry, but this is an asset and it's a highly speculative asset which has conducted some funny business and some interesting and totally reprehensible money-laundering activity," Lagarde said in an online event organized by Reuters.
The remarks, made in a conversation largely focused on the euro-area's economic outlook, show top policymakers are taking notice as a speculative fever sweeps cryptocurrency markets. Bitcoin prices have more than doubled since November and topped a record $41,000 earlier this month. Concerns over money laundering and the ability of financial firms to know the identities of their clients have been at the forefront of the cryptocurrency debate. While critics say that instruments like Bitcoin make the illicit transfer of funds easier, crypto advocates say the network of digital ledgers known as the blockchain allows money to be traced more easily than cash and can actually help law enforcement.
TikTok: All Under-16s' Accounts Made Private
TikTok users aged under 16
will have their accounts automatically set to private, as the app introduces a series of measures to improve child safety. The BBC reports:
Approved followers only can comment on videos from these accounts. Users will also be prevented from downloading any videos created by under-16s. TikTok said it hoped the changes would encourage young users to "actively engage in their online privacy journey." "We hope to inspire them to take an active role and make informed decisions," head of privacy Elaine Fox said. Those aged between 13 and 15 will be able to approve "friends" for comments and choose whether to make videos public. But those accounts will also not be "suggested" to other users on the app.
The accounts of 16- and 17-year-olds will prevent others downloading their videos - but the youngsters will have the ability to turn off this restriction. In addition, TikTok is changing this age group's default settings to allow only their chosen friends to "duet" alongside them - the name given to a facility that allows a user to record themselves in a clip then played adjacent to an earlier recording, so they can be watched simultaneously. Users will not be allowed to duet with clips made by under-16s.
Pirate Bay Founder Thinks Parler's Inability To Stay Online Is 'Embarrassing'
An anonymous reader quotes a report from Motherboard:
As one of the original co-founders of The Pirate Bay, Peter Sunde Kolmisoppi knows a little something about keeping controversial services online. Kolmisoppi and his colleagues spent decades battling a global coalition of corporations, governments, and law enforcement agencies intent on wiping the file sharing website from the face of the internet. Unsuccessfully. Kolmisoppi took to Twitter this week to share some thoughts on Parler's recent deplatforming for failing to seriously police death threats and illegal content before and after the fatal Capitol riots.
"The Pirate Bay, the most censored website in the world, started by kids, run by people with problems with alcohol, drugs and money, still is up after almost two decades," Kolmisoppi said. "Parlor and gab etc have all the money around but no skills or mindset. Embarrassing." [...] Platforming white supremacy and hate speech is a tougher proposition than serving users pirated copies of the Prince discography. But Kolmisoppi was quick to laugh at the fact that despite being backed by billionaires and parts of the US government, Parler didn't seem remotely prepared for the justified firestorm it found itself at the center of. "The most ironic thing is that The Pirate Bay's enemies include not just the US government but also many European and the Russian one," he said. "Compared to gab/parlor which is supported by the current president of the US and probably liked by the Russian one too."
"In all honesty, the reason we did The Pirate Bay was to bring freedom and take back control from a centralised system," Kolmisoppi said. "The reason that Gab et al will fail is because they're just whining bitches that have only one ideology: egotism. Sharing is caring y'all." In more recent years, Kolmoisoppi has moved on to fund Njalla, a privacy-centric domain name registration service. One he says was already asked to host Parler, and refused. "Of course we wouldn't," Kolmisoppi said. "We're pro human rights, which includes the right to not be killed by extreme right wing terrorists."
House Votes To Impeach President Trump a Historic Second Time
A House majority, including several Republicans, on Wednesday
voted to impeach President Trump for "incitement of insurrection." The New York Times reports:
The House had enough votes on Wednesday to impeach President Trump for inciting a violent insurrection against the United States government, as more than a half-dozen members of the president's party joined Democrats to charge him with high crimes and misdemeanors for an unprecedented second time. Reconvening under the threat of continued violence and the protection of thousands of National Guard troops, the House was determined to hold Mr. Trump to account just one week before he was to leave office. At issue was his role in encouraging a mob that attacked the Capitol one week ago while Congress met to affirm President-elect Joseph R. Biden Jr.'s victory, forcing lawmakers to flee for their lives in a deadly rampage.
The House put forward and was on the brink of adopting a single article of impeachment, charging Mr. Trump with "inciting violence against the government of the United States" and requesting his immediate removal from office and disqualification from ever holding one again. [...] The vote, which was still underway, set the stage for the second Senate trial of Mr. Trump in a year, though senators appeared unlikely to convene to sit in judgment before Jan. 20, when Mr. Biden will take the oath of office. The last proceeding, over Mr. Trump's attempts to pressure Ukraine to smear Mr. Biden, was a partisan affair. [...]
This time, Senator Mitch McConnell of Kentucky, the Republican leader, was said to support the effort as a means of purging his party of Mr. Trump, setting up a political and constitutional showdown that could shape the course of American politics when the nation remains dangerously divided. [McConnell said he would not agree to use emergency powers to bring the Senate back into session for a trial before Jan. 19.] The House's vote was historic. Only two other presidents have been impeached; none has been impeached twice, by such a large bipartisan margin, or so close to leaving office.
UK Nuclear Spacecraft Could Halve Time of Journey To Mars
British spacecraft could travel to Mars in half the time it now takes by using nuclear propulsion engines built by Rolls-Royce under a new deal with the UK Space Agency. From a report:
The aerospace company hopes nuclear-powered engines could help astronauts make it to Mars in three to four months, twice as fast as the most powerful chemical engines, and unlock deeper space exploration in the decades to come. The partnership between Rolls-Royce and the UK Space Agency will bring together planetary scientists to explore how nuclear energy could be used to "revolutionise space travel," according to the government. Dr Graham Turnock, the chief executive of the UK Space Agency, said using nuclear power in space was "a gamechanging concept that could unlock future deep-space missions that take us to Mars and beyond."
BeagleV is a $150 RISC-V Computer Designed To Run Linux
Seeed Studios -- the makers of the Odyssey mini-PC -- have teamed up with well-known SBC vendor BeagleBoard to produce an affordable RISC-V system designed to run Linux. The new BeagleV (pronounced "Beagle Five") system features a dual-core, 1GHz RISC-V CPU made by StarFive -- one of a network of RISC-V startups created by better-known RISC-V vendor SiFive. The CPU is based on two of SiFive's U74 Standard Cores -- and unlike simpler microcontroller-only designs, it features a MMU and all the other trimmings necessary to run full-fledged modern operating systems such as Linux distributions. StarFive's VIC7100 processor design is aimed at edge AI tasks as well as general-purpose computing. In addition to the two RISC-V CPU cores, it features a Tensilica Vision VP6 DSP for machine-vision applications, a Neural Network Engine, and a single-core NVDLA (Nvidia Deep Learning Accelerator) engine.
Airbnb Blocks DC Reservations Around Inauguration
Airbnb said Wednesday it is canceling existing reservations and
blocking new ones in the Washington, D.C., area during inauguration week as federal officials remain on alert for potential violence. Axios reports:
Airbnb says the move is in response to requests from local, state and federal officials asking people not to travel to D.C. for President-elect Biden's inauguration. Guests whose reservations are canceled will receive refunds and Airbnb says it will reimburse hosts' lost earnings.
"We are aware of reports emerging yesterday afternoon regarding armed militias and known hate groups that are attempting to travel and disrupt the Inauguration," the company said in its announcement. Airbnb also said it has banned from its platform numerous individuals it has learned that are "either associated with known hate groups or otherwise involved in the criminal activity at the Capitol Building."
Ubisoft To Make Star Wars Game, Marking End To EA Exclusivity
Ubisoft said it will
develop a new Star Wars game, indicating a longtime exclusivity agreement for Electronic Arts on the Walt Disney franchise will come to an end. From a report:
The new Star Wars title is set to be the first not published by EA since Disney acquired Lucasfilm in 2012. The news sent shares of the two game companies diverging Wednesday. Ubisoft climbed more than 7%, and EA fell as much 3.2%. The agreement with EA is scheduled to expire in 2023. In an emailed statement, EA said: "We're proud of our long-standing collaboration with Lucasfilm Games, which will continue for years to come." Lucasfilm said in a blog post Wednesday morning that it had "a number of projects underway" with EA. Ubisoft said only that its game will be set in an open-world environment and will developed by the company's Massive Entertainment team in Sweden, best known for a series of shooting games called Tom Clancy's The Division. The group is also working on a game based on James Cameron's "Avatar" movies.
Apple Invests Millions To Back Entrepreneurs of Color, Part of Racial Justice Effort
Apple on Wednesday said it was putting $60 million into
a fresh round of projects aimed at challenging systemic racism, including its first foray into venture capital funding to back entrepreneurs of color. From a report:
Apple said it would invest $10 million in a fund with Harlem Capital, a New York-based early-stage venture firm, with the goal of helping fund 1,000 companies over 20 years. Apple will invest $25 million in Siebert Williams Shank's Clear Vision Impact Fund, which provides financing to small- and mid-sized businesses, with an emphasis on minority-owned firms. Apple will become a limited partner in funds at both.
Dropbox To Cut 11% of its Global Workforce
cutting its global workforce by about 11%, the company said in an 8K filing released Wednesday. From a report:
The move will affect 315 people, who will be notified by the end of the business day. "The steps we're taking today are painful, but necessary," Dropbox CEO Drew Houston said in an employee memo Wednesday. Dropbox committed to preserve job security through 2020, but Houston said that looking ahead to this year "it's clear that we need to make changes in order to create a healthy and thriving business for the future." The company said the job cuts will help it focus on its top priorities for the year, which include evolving the core Dropbox experience, investing in new products and driving operational excellence.
Debian Discusses Vendoring -- Again
writing at LWN:
This time around, Raphael Hertzog raised the issue with regard to the Greenbone Security Assistant (gsa), which provides a web front-end to the OpenVAS vulnerability scanner (which is now known as Greenbone Vulnerability Management or gvm). "the version currently in Debian no longer works with the latest gvm so we have to update it to the latest upstream release... but the latest upstream release has significant changes, in particular it now relies on yarn or npm from the node ecosystem to download all the node modules that it needs (and there are many of them, and there's no way that we will package them individually). The Debian policy forbids download during the build so we can't run the upstream build system as is."
Signal's Brian Acton Talks About Exploding Growth, Monetization and WhatsApp Data-Sharing Outrage
Brian Acton is crossing paths again with Facebook. From a report:
Over more than a decade of building and operating WhatsApp, the company's co-founder first competed against and then sold his instant messaging app to the social juggernaut. Only a few years ago he parted ways with the company that made him a billionaire in a bitter split over messaging and privacy. Now Acton says the ongoing outrage over what Facebook has done to the messaging service he helped build is driving people to his latest project -- Signal. Acton, who serves as the executive chairman of the privacy-conscious messaging app's holding company, told TechCrunch in an interview that the user base of Signal has "exploded" in recent weeks. "The smallest of events helped trigger the largest of outcomes," said Acton on a video call. "We're also excited that we are having conversations about online privacy and digital safety and people are turning to Signal as the answer to those questions." "It's a great opportunity for Signal to shine and to give people a choice and alternative. It was a slow burn for three years and then a huge explosion. Now the rocket is going," he said. The event Acton is referring to is the recent change in data-sharing policy disclosed by WhatsApp, an app that serves more than 2 billion users worldwide.

NASA Spacecraft Discovers the Universe is Less Crowded Than We Thought
An anonymous reader shares a report:
While we might think of space as a vast sea of blackness, all we have to do is look up at night to see that it's punctuated by countless stars, galaxies and even a few planets visible to the naked eye. Scientists recently used data from NASA's New Horizons mission out beyond Pluto to measure just how dark the cosmic background really is. What they found has implications for what we thought we knew about the makeup of the entire universe. In short, space is so dark there can't be as many galaxies out there, adding their faint glow to the backdrop, as astronomers have previously estimated.
"It's an important number to know -- how many galaxies are there?" Marc Postman of the Space Telescope Science Institute said in a statement Tuesday. "We simply don't see the light from 2 trillion galaxies." That was the earlier estimate derived from Hubble Space Telescope observations, but a new study forthcoming in the Astrophysical Journal and co-authored by Postman suggests the total number of galaxies in the universe is probably in the hundreds of billions rather than the trillions. Interestingly, this is closer to an even earlier figure guessing there were around 200 billion galaxies. That was based on Hubble data from the 1990s.
Plaid Pulled Plug on Visa Deal Over Price, Not Antitrust Concerns
no longer be buying fintech upstart Plaid, as the companies on Tuesday announced the "mutual termination" of the $5.3 billion agreement that was signed one year ago and opposed by U.S. antitrust regulators. From a report:
This is more about the rising value of fintech companies than it is about the U.S. Justice Department. It also turns Plaid into a very appealing target for growth equity investors, IPO bankers and SPAC sponsors. DOJ sued to block the deal in November, claiming it would eliminate Plaid's future ability to compete in the online debit market, thus giving Visa a monopoly. Visa said it would vigorously defend itself, in part because Plaid has no online debit products nor any in the pipeline. Visa also sought an expedited process to begin in the spring, whereas DOJ sought a December trial. The two sides met just before the holidays, but I'm told that DOJ would only agree to split the difference.
Disappointing Chinese Vaccine Results Pose Setback for Developing World
Scientists in Brazil have downgraded the efficacy of a Chinese coronavirus vaccine that they hailed as a major triumph last week, diminishing hopes for a shot that could be quickly produced and easily distributed to help the developing world. From a report:
Officials at the Butantan Institute in Sao Paulo said on Tuesday that a trial conducted in Brazil showed that the CoronaVac vaccine, manufactured by the Beijing-based company Sinovac, had an efficacy rate just over 50 percent. That rate, slightly above the benchmark that the World Health Organization has said would make a vaccine effective for general use, was far below the 78 percent level announced last week. The implications could be significant for a vaccine that is crucial to China's global health diplomacy. At least 10 countries have ordered more than 380 million doses of the Sinovac inoculation, CoronaVac, though regulatory agencies have yet to fully approve it.
A senior official in Hong Kong, a special administrative region of China that had already ordered CoronaVac, said on Wednesday that an advisory panel would strictly review the vaccine based on clinical trial data before it was rolled out there. "Those countries that have ordered the Chinese-made vaccines are probably going to question the usefulness of these vaccines," said Yanzhong Huang, a senior fellow for global health at the Council on Foreign Relations and an expert on health care in China. "Countries with opposition parties might use this to challenge the decision made by the incumbent government, and that will likely have domestic political implications in these countries," Mr. Huang said. Sinovac did not respond to multiple requests for comment.
Intel CEO Bob Swan To Step Down in February, VMware CEO Pat Gelsinger To Replace Him
Intel CEO Bob Swan is
set to step down effective Feb. 15. From a report:
VMWare CEO Pat Gelsinger will take over the position, sources told CNBC. Intel's stock was up about 13% in premarket trading following the news. VMWare's stock was down nearly 5%. Swan was named CEO in January 2019 after serving as interim CEO for seven months. During Swan's tenure, Intel has suffered blows from competitors. Over the summer, Intel reported that its latest generation chips would be delayed while AMD's were already shipping inside laptops. Apple announced in the fall that it would use its own proprietary chips in its Mac computers, breaking a 15-year partnership with Intel for its chip supplies.
EPA Raises Barriers To Climate-Change Rules
The Environmental Protection Agency is creating higher barriers for regulating the emissions that contribute to climate change, setting new rules that effectively block the federal government from imposing new restrictions on several heavy industries. From a report:
The agency, which first introduced a proposal to create the higher bar in August, packaged these new standards in a rule making it issued Tuesday. The rule, to be published in the Federal Register Wednesday, sets new criteria for what is considered a significant contributor of greenhouse-gas emissions. In the rule the agency says that determination is required by law and finds that oil and gas producers, refiners, steelmakers and other heavy industries don't meet the criteria, prohibiting the EPA from regulating their emissions under the Clean Air Act.
Tuesday's action may not have staying power, however. President-elect Joe Biden's team has announced plans to freeze and potentially undo any new regulations, such as this one, that are still pending when it takes power next week. The Biden transition team didn't immediately respond to a request for comment. Mr. Biden, however, has criticized the Trump administration for rolling back environmental regulations aimed at arresting climate change. President Trump has pushed for ways to check expanding environmental regulations, saying they hurt U.S. businesses like manufacturers and energy producers.
WhatsApp Clarifies It's Not Giving All Your Data To Facebook
An anonymous reader quotes a report from The Verge:
But a wave of misinformation on social media, not helped by Facebook's abysmal track record on privacy and its reputation for obfuscating changes to its various terms of service agreements, has resulted in a full-blown WhatsApp backlash that has users fleeing to competitors like Signal and Telegram. [...] WhatsApp executives, as well as Instagram chief Adam Mosseri and Facebook AR / VR head Andrew "Boz" Bosworth, are now trying to set the record straight, perhaps to little avail at this point.
"We want to be clear that the policy update does not affect the privacy of your messages with friends or family in any way. Instead, this update includes changes related to messaging a business on WhatsApp, which is optional, and provides further transparency about how we collect and use data," the company writes on the new FAQ page. It also stresses in the FAQ that neither Facebook nor WhatsApp read users' message logs or listen to their calls, and that WhatsApp doesn't store user location data or share contact information with Facebook. (It's also worth noting that data sharing with Facebook is extremely limited for European users due to stronger user privacy protections in the EU.) WhatsApp chief Will Cathcart also took to Twitter a few days ago to post a thread (later shared by Bosworth in the tweet above) trying to cut through the confusion and explain what's actually going on. "With end-to-end encryption, we cannot see your private chats or calls and neither can Facebook. We're committed to this technology and committed to defending it globally," Cathcart wrote. "It's important for us to be clear this update describes business communication and does not change WhatsApp's data sharing practices with Facebook. It does not impact how people communicate privately with friends or family wherever they are in the world."
Most Distant Quasar Discovered Sheds Light On How Black Holes Grow
fahrbot-bot shares a report from Phys.Org:
A team of astronomers led by the University of Arizona has observed a luminous quasar 13.03 billion light-years from Earth -- the most distant quasar discovered to date. Dating back to 670 million years after the Big Bang, when the universe was only 5% its current age, the quasar hosts a supermassive black hole equivalent to the combined mass of 1.6 billion suns.
In addition to being the most distant -- and by extension, earliest -- quasar known, the object is the first of its kind to show evidence of an outflowing wind of super-heated gas escaping from the surroundings of the black hole at a fifth of the speed of light. In addition to revealing a strong quasar-driven wind, the new observations also show intense star formation activity in the host galaxy where the quasar, formally designated J0313-1806, is located. The researchers will present their findings, which have been accepted for publication in Astrophysical Journal Letters, during a press conference and a scientific talk at the 237th Meeting of the American Astronomical Society, which will be held virtually Jan. 11-15.
YouTube Suspends Trump's Channel For At Least 7 Days
taken action against President Donald Trump and
barred new videos from being uploaded to his channel for at least seven days, citing violations of its policies and "concerns about the ongoing potential for violence." NBC News reports:
It's the latest action against Trump after last week's deadly riot at the U.S. Capitol by a pro-Trump mob. Twitter and Facebook have both also suspended or blocked the president's accounts. YouTube issued "a strike" to Trump's channel, and said comments would also be disabled indefinitely. The company also said it removed new content posted Tuesday.
