necro81 writes: Back in March 2020, NASA shut down the Australia dish in its Deep Space Network for repairs and upgrades. For the duration of the outage, NASA had no means for communicating with Voyager 2. From the NYTimes:

On Friday, Earth's haunting silence will come to an end as NASA switches that communications channel back on, restoring humanity's ability to say hello to its distant explorer.

Because of the direction in which it is flying out of the solar system, Voyager 2 can only receive commands from Earth via one antenna in the entire world. It's called DSS 43 and it is in Canberra, Australia. It is part of the Deep Space Network, or DSN, which along with stations in California and Spain, is how NASA and allied space agencies stay in touch with the armada of robotic spacecraft exploring everything from the sun's corona to the regions of the Kuiper belt beyond the orbit of Pluto. (Voyager 2's twin, Voyager 1, is able to communicate with the other two stations.)

A round-trip communication with Voyager 2 takes about 35 hours --17 hours and 35 minutes each way....

While Voyager 2 was able to call home on the Canberra site's smaller dishes during the shutdown, none of them could send commands to the probe....

NASA ... did send one test message to the spacecraft at the end of October when the antenna was mostly reassembled.

An international team of astronomers has found signs that a habitable planet may be lurking in Alpha Centauri, a binary star system a mere 4.37 light-years away. It could be one of the closest habitable planet prospects to date, although it's probably not much like Earth if it exists. From a report: The new findings: The Alpha Centauri system's potential to host life-bearing worlds has always intrigued scientists, but no known exoplanets have ever been established there -- in part because the close proximity meant it was too bright for astronomers to really narrow in on any planetary objects in the area. But in a paper published in Nature Communications on Wednesday, an international team of astronomers using the European Southern Observatory's Very Large Telescope (VLT) in Chile found a bright thermal imaging signal coming from the habitable zone of Alpha Centauri A. The signal was derived through Near Earths in the Alpha Center Region (NEAR), a $3 million project supported by the ESO and Breakthrough Watch. The latter is an initiative backed by Russian billionaire Yuri Milner to look for Earth-size rocky planets around Alpha Centauri and other star systems within 20 light-years of us. NEAR was able to push forward upgrades to the VLT that included a thermal chronograph, which can block stellar light and look for heat signatures coming from planetary objects as they reflect the light from their star. It found the signal around Alpha Centauri A after analyzing 100 hours of data.

"The U.S. app Clubhouse erupted among Chinese social-media users over the weekend," reports Bloomberg, "with thousands joining discussions on contentious subjects...undisturbed by Beijing's censors." On the invite-only, audio-based social app where users host informal conversations, Chinese-speaking communities from around the world gathered to discuss China-Taiwan relations and the prospects of unification, and to share their knowledge and experience of Beijing's crackdown on Muslim Uighurs in the far west region of Xinjiang. Open discussion of such topics is off limits in China, where heavy government censorship is the norm...

On Friday night, a room attracted more than 4,000 people from both sides of the Taiwan Strait to share their stories and views on a range of topics including uniting the two sides. In another room on Saturday, several members of the Uighur ethnic community now living overseas shared their experience of events in Xinjiang, where China has rolled out a widely criticized re-education program that saw an estimated 1 million people or more put into camps...

"Thanks to Clubhouse I have the freedom and the audience to express my opinion," a Finland-based doctor and activist who goes by Halmurat Harri Uyghur told Bloomberg News.
Bloomberg spoke to Michael Norris, a research/strategy manager at a Shanghai-based consultancy, who said most Chinese Clubhouse users he'd spoken to are part of the tech/investment/marketing world. "Those who do engage in political discussion on Clubhouse take on a degree of personal risk," he said. "While most are aware Clubhouse records real names, phone numbers and voice, they are broadly unaware about recent cases in China involving interrogation and jail for errant posts on Twitter." Since Clubhouse so far is only accessible on Apple Inc.'s iPhone and users must have a non-Chinese Apple account, the app has only gained traction among a small cohort of educated citizens, according to Fang Kecheng, a communications professor at the Chinese University of Hong Kong. "I don't think it can really reach the general public in China," he said. "If so, it will surely get blocked."
Reuters highlights the significance of the event: "I don't know how long this environment can last", said one user in a popular Weibo post that was liked over 65,000 times. "But I will definitely remember this moment in Internet history."

Slashdot reader GatorSnake shares "Another take of the implications of Section 230... One person poisoned the online personas of multiple people who had 'wronged' her, with it being nearly impossible to have the false accusations removed from the sites or from Google's search results."

The New York Times reports: Mr. Babcock, a software engineer, got off the phone and Googled himself. The results were full of posts on strange sites accusing him of being a thief, a fraudster and a pedophile. The posts listed Mr. Babcock's contact details and employer. The images were the worst: photos taken from his LinkedIn and Facebook pages that had "pedophile" written across them in red type. Someone had posted the doctored images on Pinterest, and Google's algorithms apparently liked things from Pinterest, and so the pictures were positioned at the very top of the Google results for "Guy Babcock."

Mr. Babcock, 59, was not a thief, a fraudster or a pedophile. "I remember being in complete shock," he said. "Why would someone do this? Who could it possibly be? Who would be so angry?" Then he Googled his brother's name. The results were just as bad. He tried his wife. His sister. His brother-in-law. His teenage nephew. His cousin. His aunt. They had all been hit. The men were branded as child molesters and pedophiles, the women as thieves and scammers...

Ripoff Report offered "arbitration services," which cost up to $2,000, to get rid of "substantially false" information. That sounded like extortion; Mr. Babcock wasn't about to pay to have lies removed... Ripoff Report is one of hundreds of "complaint sites" — others include She's a Homewrecker, Cheaterbot and Deadbeats Exposed — that let people anonymously expose an unreliable handyman, a cheating ex, a sexual predator. But there is no fact-checking. The sites often charge money to take down posts, even defamatory ones. And there is limited accountability. Ripoff Report, like the others, notes on its site that, thanks to Section 230 of the federal Communications Decency Act, it isn't responsible for what its users post.

"If someone posts false information about you on the Ripoff Report, the CDA prohibits you from holding us liable for the statements which others have written. You can always sue the author if you want, but you can't sue Ripoff Report just because we provide a forum for speech...."
The Times found over 100 so-called "complaint" sites with more defamatory posts — Babcock's brother-in-law calculates there've been 12,000 made by the same person. The Times ultimately attributes the posts to a disgruntled employee fired by Mr. Babcock's father — in the year 1993 — who was now using a computer in a public library at the University of Toronto.

"Under U.S. law, a foreign court generally can't force an American website to remove content..." the Times notes, leaving few options for the victims they'd interviewed. "Victims spent years begging Google, Pinterest and WordPress to take down the slanderous posts or at least make them harder to find. The companies rarely did so, until I contacted them to request comment for this article. Pinterest then removed photos... Automattic, which owns WordPress, deleted her blogs."

But not Google Images.

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare. Phys.Org reports: Army researchers built the quantum sensor, which can sample the radio-frequency spectrum -- from zero frequency up to 20 GHz -- and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals. The Rydberg sensor uses laser beams to create highly-excited Rydberg atoms directly above a microwave circuit, to boost and hone in on the portion of the spectrum being measured. The Rydberg atoms are sensitive to the circuit's voltage, enabling the device to be used as a sensitive probe for the wide range of signals in the RF spectrum.

The Rydberg spectrum analyzer has the potential to surpass fundamental limitations of traditional electronics in sensitivity, bandwidth and frequency range. Because of this, the lab's Rydberg spectrum analyzer and other quantum sensors have the potential to unlock a new frontier of Army sensors for spectrum awareness, electronic warfare, sensing and communications -- part of the Army's modernization strategy. The peer-reviewed journal Physical Review Applied published the researchers' findings, Waveguide-coupled Rydberg spectrum analyzer from 0 to 20 GigaHerz, co-authored by Army researchers Drs. David Meyer, Paul Kunz, and Kevin Cox.

Myanmar's new military government has ordered local telecom operators, internet gateways, and other internet service providers to block Twitter and Instagram in the South Asian country days after imposing a similar blackout on Facebook to ensure "stability" in the Southeast Asian nation. From a report: Norwegian telecom giant Telenor, which is one of the largest telecos in Myanmar, said the government has ordered ISPs to block Twitter and Instagram "until further notice." The directive has "legal basis in Myanmar's telecommunications law," Telenor said, but it is challenging the "necessity and proportionality of the directive in its response to Myanmar Ministry of Transport and Communications, and highlighted the directive's contradiction with international human rights law."

[...] In a statement, a Twitter spokesperson told TechCrunch: "We're deeply concerned about the order to block Internet services in Myanmar. It undermines the public conversation and the rights of people to make their voices heard. The Open Internet is increasingly under threat around the world. We will continue to advocate to end destructive government-led shutdowns. We understand some people across the Asia-Pacific region may also be having trouble accessing Twitter, and we're working to fix it."

More than two dozen Dropbox employees say they've witnessed or experienced gender discrimination at the company, an investigation by news outlet VentureBeat has found. From a report: In December 2020, a source familiar with the matter sent VentureBeat a document containing anonymous interviews with 16 current and former Dropbox employees who allege gender discrimination at the cloud computing company. The report alleging discrimination began circulating internally after its author sent it to Dropbox employees throughout North America on December 9. Compiled by a former Dropbox researcher, the report was not commissioned by Dropbox executives and is strongly contested by the company. "When I first read the email, when the report was sent out, I started crying," Source 1, who said she had experienced discrimination with regard to promotion at Dropbox, told VentureBeat. "I was frustrated and almost livid that so many other people were experiencing it, too. I really hoped that my personal experience was a one-off, and it was jarring and really upsetting to see so many things that could have been my story." The subjects of the report alleging discrimination point to examples such as "changing standards for promotions, unequal compensation, being set back in their careers after maternity leave, and experiencing retribution when they take their cases to HR." The report also detailed instances of alleged harassment and demotion after employees filed a complaint with Dropbox HR or returned to work following maternity leave. Internal communications VentureBeat obtained indicate that more than a dozen Dropbox employees agreed with the report's conclusions.

Three Democratic U.S. senators introduced a bill that would limit Section 230, a law that shields online companies from liability over content posted by users, and make the companies more accountable when posts result in harm. From a report: Called the SAFE TECH Act, the bill would mark the latest effort to make social media companies like Alphabet's Google, Twitter and Facebook more accountable for "enabling cyber-stalking, targeted harassment, and discrimination on their platforms," Senators Mark Warner, Mazie Hirono and Amy Klobuchar said in a statement. In the wake of the Jan. 6 storming of the U.S. Capitol in Washington, lawmakers have been studying ways to hold Big Tech more accountable for the role they played in the spread of disinformation before the riot and about policing content on their platforms. The bill would make it clear that Section 230, which was enacted in 1996 as part of a law called the Communications Decency Act, does not apply to ads or other paid content, does not impair the enforcement of civil rights laws, and does not bar wrongful-death actions.

SpaceX disclosed in a public filing on Thursday that its Starlink satellite internet service now has "over 10,000 users in the United States and abroad." From a report: "Starlink's performance is not theoretical or experimental ... [and] is rapidly accelerating in real time as part of its public beta program," SpaceX wrote in a filing with the Federal Communications Commission. Elon Musk's company began a public beta program of Starlink in October, with service priced at $99 a month, in addition to a $499 upfront cost to order the Starlink Kit, which includes a user terminal and Wi-Fi router to connect to the satellites.

Microsoft today launched Viva, a new "employee experience platform," or, in non-marketing terms, its new take on the intranet sites most large companies tend to offer their employees. From a report: This includes standard features like access to internal communications built on integrations with SharePoint, Yammer and other Microsoft tools. In addition, Viva also offers access to team analytics and an integration with LinkedIn Learning and other training content providers (including the likes of SAP SuccessFactors), as well as what Microsoft calls Viva Topics for knowledge sharing within a company. If you're like most employees, you know that your company spends a lot of money on internal communications and its accompanying intranet offerings -- and you then promptly ignore that in order to get actual work done. But Microsoft argues that times are changing, as remote work is here to stay for many companies, even after the pandemic (hopefully) ends. Even if a small percentage of a company's workforce remains remote or opts for a hybrid approach, those workers still need to have access to the right tools and feel like they are part of the company.

[...] Unsurprisingly, Viva is powered by Microsoft 365 and all of the tools that come with that, as well as integrations with Microsoft Teams, the company's flagship collaboration service, and even Yammer, the employee communication tool it acquired back in 2012 and continues to support. There are several parts to Viva: Viva Connections for accessing company news, policies, benefits and internal communities (powered by Yammer); Viva Learning for, you guessed it, accessing learning resources; and Viva Topics, the service's take on company-wide knowledge sharing. For the most part, that's all standard fair in any modern intranet, whether it's from a startup provider or an established player like Jive.

A man who has been an AT&T customer since 1960 has a message for CEO John Stankey about the company's failure to upgrade DSL areas to modern Internet service. Aaron Epstein, 90, is so frustrated by his 3Mbps Internet plan that he took out a Wall Street Journal ad in today's print edition in order to post an open letter to Stankey. From a report: "Dear Mr. Stankey: AT&T prides itself as a leader in electronic communications. Unfortunately, for the people who live in N. Hollywood, CA 91607, AT&T is now a major disappointment," Epstein wrote in the letter. Epstein paid $1,100 to run the ad for one day in the Manhattan and Dallas editions of today's Journal, he told Ars in a phone interview. He chose the Manhattan edition to reach investors who might want to pressure AT&T into upgrading its network and Dallas because that's where AT&T is headquartered, he said. "We need to keep up with current technology and have looked to AT&T to supply us with fast Internet service," Epstein wrote in the open letter to AT&T's CEO. "Yet, although AT&T is advertising speeds up to 100Mbps for other neighborhoods, the fastest now available to us from AT&T is only 3Mbps. Your competitors now have speeds of over 200Mbps. Why is AT&T, a leading communications company, treating us so shabbily in North Hollywood?"

"Huawei, the crown jewel of China's technology industry, has suffered from a sustained American campaign to keep its equipment from being used in new 5G networks around the world," reports the New York Times. Now they've identified "a covert pro-Huawei influence campaign in Belgium about 5G networks." [Alternate URL here]

It began when trade lawyer Edwin Vermulst was paid to write an article criticizing a Belgian policy that would block Huawei from lucrative contracts: First, at least 14 Twitter accounts posing as telecommunications experts, writers and academics shared articles by Mr. Vermulst and many others attacking draft Belgium legislation that would limit "high risk" vendors like Huawei from building the country's 5G system, according to Graphika, a research firm that studies misinformation and fake social media accounts. The pro-Huawei accounts used computer-generated profile pictures, a telltale sign of inauthentic activity. Next, Huawei officials retweeted the fake accounts, giving the articles even wider reach to policymakers, journalists and business leaders. Kevin Liu, Huawei's president for public affairs and communications in Western Europe, who has a verified Twitter account with 1.1 million followers, shared 60 posts from the fake accounts over three weeks in December, according to Graphika. Huawei's official account in Europe, with more than five million followers, did so 47 times...

Twitter said it had removed the fake accounts after Graphika alerted it to the campaign on Dec. 30... Many of their followers appeared to be bots...

The effort suggests a new twist in social media manipulation, said Ben Nimmo, a Graphika investigator who helped identify the pro-Huawei campaign. Tactics once used mainly for government objectives — like Russia's interference in the 2016 American presidential election — are being adapted to achieve corporate goals. "It's business rather than politics," Mr. Nimmo said. "It's not one country targeting another country. It looks like an operation to promote a major multinational's interests — and to do it against a European state."
Though the social media campaign had little impact on Belgian policymakers, one telecom consultancy noted Huawei's fear that similar legislation "could spread to other parts of the world." (The article points out Belgium is the headquarters of both NATO and the European Union.)

But Phil Howard, the director of the Oxford Internet Institute, see a future where disinformation will become increasingly commercialized. "The flow of money is increasingly there," he tells the Times. "Large-scale social media influence operations are now part of the communications tool kit for any large global corporation."

Robin George Andrews, reporting for National Geographic: A 62-year-old adventure mystery that has prompted conspiracy theories around Soviet military experiments, Yetis, and even extraterrestrial contact may have its best, most sensible explanation yet -- one found in a series of avalanche simulations based in part on car crash experiments and animation used in the movie Frozen. In an article published this week in the journal Communications Earth and Environment, researchers present data pointing to the likelihood that a bizarrely small, delayed avalanche may have been responsible for the gruesome injuries and deaths of nine experienced hikers who never returned from a planned 200-mile adventure in Russia's Ural Mountains in the winter of 1959.

In what has become known as the Dyatlov Pass incident, ten members of the Urals Polytechnic Institute in Yekaterinburg -- nine students and one sports instructor who fought in World War II -- headed into the frigid wilderness on a skiing and mountaineering expedition on January 23, 1959. One student with joint pain turned back, but the rest, led by 23-year-old engineering student Igor Dyatlov, continued on. According to camera film and personal diaries later found on the scene by investigators, the team made camp on February 1, pitching a large tent on the snowy slopes of Kholat Saykhl, whose name can be interpreted as "Dead Mountain" in the language of the region's Indigenous Mansi people. The nine -- seven men and two women -- were never heard from again.

When a search team arrived at Kholat Saykhl a few weeks later, the expedition tent was found just barely sticking out of the snow, and it appeared cut open from the inside. The next day, the first of the bodies was found near a cedar tree. Over the next few months, as the snow thawed, search teams gradually uncovered more spine-chilling sights: All nine of the team members' bodies were scattered around the mountain's slope, some in a baffling state of undress; some of their skulls and chests had been smashed open; others had eyes missing, and one lacked a tongue. Each body was a piece in a grim puzzle, but none of the pieces seemed to fit together. A criminal investigation at the time blamed their deaths on an "unknown natural force," and the Soviet bureaucracy kept the case quiet. The lack of detail about this shocking event, an apparent massacre that transpired in a deeply secretive state, gave rise to dozens of long-lived conspiracy theories, from clandestine military tests to Yeti attacks.

Four European apps which secure user data via end-to-end encryption, ProtonMail, Threema, Tresorit and Tutanota, have issued a joint-statement warning over recent moves by EU institutions that they say are setting lawmakers on a dangerous path to backdooring encryption. From a report: Last month the EU Council passed a resolution on encryption that's riven with contradiction -- calling for "security through encryption and security despite encryption" -- which the four e2e app makers believe is a thinly veiled call to backdoor encryption. The European Commission has also talked about seeking "improved access" to encrypted information, writing in a wide-ranging counter-terrorism agenda also published in December that it will "work with Member States to identify possible legal, operational, and technical solutions for lawful access." Simultaneously, the Commission has said it will "promote an approach which both maintains the effectiveness of encryption in protecting privacy and security of communications, while providing an effective response to crime and terrorism." And it has made it clear there will be no 'one silver bullet' as regards the e2e encryption security 'challenge.' But such caveats are doing nothing to alleviate the concerns of e2e encrypted app makers -- who are convinced proposals from the Council of the EU, which is involved in adopting the bloc's laws (though the Commission usually drafts legislation), sums to an push toward backdoors.

"While it's not explicitly stated in the resolution, it's widely understood that the proposal seeks to allow law enforcement access to encrypted platforms via backdoors," the four app makers write, going on to warn that such a move would fatally underline the security EU institutions also claim to want to maintain. "The resolution makes a fundamental misunderstanding: Encryption is an absolute, data is either encrypted or it isn't, users have privacy or they don't," they go on. "The desire to give law enforcement more tools to fight crime is obviously understandable. But the proposals are the digital equivalent of giving law enforcement a key to every citizen's home and might begin a slippery slope towards greater violations of personal privacy."

sciencehabit shares a report from Science Magazine: Researchers have discovered a common martian mineral deep within an ice core from Antarctica. The find suggests the mineral -- a brittle, yellow-brown substance known as jarosite -- was forged the same way on both Earth and Mars: from dust trapped within ancient ice deposits. It also reveals how important these glaciers were on the Red Planet: Not only did they carve valleys, the researchers say, but they also helped create the very stuff Mars is made of.

Jarosite was first spotted on Mars in 2004, when the NASA Opportunity rover rolled over fine-grained layers of it. The discovery made headlines because jarosite needs water to form, along with iron, sulfate, potassium, and acidic conditions. The work suggests jarosite forms the same way on Mars, says Megan Elwood Madden, a geochemist at the University of Oklahoma who was not involved with the research. But she wonders whether the process can explain the huge abundance of jarosite on Mars. "On Mars, this is not just some thin film," she says. "These are meters-thick deposits."

[Giovanni Baccolo, a geologist at the University of Milan-Bicocca] concedes that the ice core contained only small amounts of jarosite, particles smaller than an eyelash or a grain of sand. But he explains that there's much more dust on Mars than in Antarctica, which only receives small amounts of airborne ash and dirt from northern continents. "Mars is such a dusty place -- everything is covered in dust," Baccolo says. More ash would favor more jarosite formation under the right conditions, he says. Baccolo wants to use Antarctic cores to investigate whether ancient martian ice deposits were cauldrons for the formation of other minerals. He says jarosite shows how glaciers weren't just land carving machines, but might have contributed to Mars's chemical makeup. "This is just the first step in linking deep Antarctic ice with the martian environment." The researchers reported their findings this month in Nature Communications.

SpaceX has begun launching Starlink satellites with laser links that will help provide broadband coverage in polar regions. As SpaceX CEO Elon Musk wrote on Twitter on Sunday, these satellites "have laser links between the satellites, so no ground stations are needed over the poles." From a report: The laser links are included in 10 Starlink satellites just launched into polar orbits. The launch came two weeks after SpaceX received Federal Communications Commission approval to launch the 10 satellites into polar orbits at an altitude of 560km. "All sats launched next year will have laser links," Musk wrote in another tweet yesterday, indicating that the laser systems will become standard on Starlink satellites in 2022. For now, SpaceX is only including laser links on polar satellites. "Only our polar sats have lasers this year & are v0.9," Musk wrote. Alaskan residents will benefit from the polar satellites, SpaceX told the FCC in an application to change the orbit of some of its satellites in April 2020.

Google said today that a North Korean government hacking group has targeted members of the cyber-security community engaging in vulnerability research. From a report: The attacks have been spotted by the Google Threat Analysis Group (TAG), a Google security team specialized in hunting advanced persistent threat (APT) groups. In a report published earlier today, Google said North Korean hackers used multiple profiles on various social networks, such as Twitter, LinkedIn, Telegram, Discord, and Keybase, to reach out to security researchers using fake personas. Email was also used in some instances, Google said. "After establishing initial communications, the actors would ask the targeted researcher if they wanted to collaborate on vulnerability research together, and then provide the researcher with a Visual Studio Project," said Adam Weidemann, a security researcher with Google TAG.

Ars Technica reported Saturday that "The Falcon 9 rocket was ready. Its payload of 143 satellites were ready. But Mother Nature was not ready."

Although SpaceX pressed ahead with fueling of the Falcon 9 booster on Saturday morning, the company scrubbed the launch attempt of the Transporter-1 mission a few minutes before the window opened due to weather. Conditions at Cape Canaveral violated the electrical field rule for a safe launch. The company now plans to try to launch again on Sunday morning, with the launch window opening at 10am ET (15:00 UTC).
Slashdot noted earlier that SpaceX plans to launch the most satellites ever deployed in a single mission, 143, from Florida for more than a dozen customers. UPI reports: A 2017 mission by the India Space Research Organization launched 104 spacecraft, which would be the previous record if the SpaceX launch is a success... The Transporter-1 mission is the first in a series of regularly scheduled SpaceX rideshare projects for multiple customers. SpaceX also plans to carry 10 of its Starlink communications satellites on this mission.

"The Starlink satellites aboard this mission will be the first in the constellation to deploy to a polar orbit," according to the SpaceX mission description. Polar orbits circle the globe by passing over the North Pole and South Pole, while many satellites circle above equatorial regions. Houston-based space firm Nanoracks is acting as a broker to arrange some customers for the launch, said Tristan Prejean, a mission manager at Nanoracks. Nanoracks' two customers for Transporter-1 are two satellite companies, California-based Spire Global and Montreal-based GHGSat. Spire launches fleets of small satellites that monitor weather and patterns for shipping for aviation interests. GHGSat monitors industrial emissions of gasses from space -- especially greenhouse gases that contribute to climate change.

Amazon has extended an offer to President Joe Biden to assist with the national distribution of Covid-19 vaccines, a move that could expedite the federal effort to combat the pandemic. From a report: Dave Clark, the CEO of Amazon's consumer business, and one of the company's highest-ranking executives, sent a letter to the president shortly after he was sworn in Wednesday. "As you begin your work leading the country out of the COVID-19 crisis, Amazon stands ready to assist you in reaching your goal of vaccinating 100 million Americans in the first 100 days of your administration," he wrote in his letter, a copy of which was obtained by NBC News.

"We are prepared to leverage our operations, IT, & communications capabilities and expertise to assist your administration's vaccination efforts," Clark wrote. "Our scale allows us to make a meaningful impact immediately in the fight against COVID-19, and we stand ready to assist you in this effort." Clark said Amazon had agreements in place with licensed third-party health care providers to administer vaccines on-site at Amazon facilities. "We are prepared to move quickly once vaccines are available," he wrote.

Scientists from a trio of universities have combined satellite imagery with deep learning to detect elephants from space. The goal is to help protect these endangered species from poachers or habitat destruction. Their study was published in the journal Ecology and Conservation. Interesting Engineering reports: The team's method proved comparable to human detection accuracy and could help solve a number of existing challenges, such as cross-border limits, and cloud coverage, among others. The team used Maxar WorldView-3 satellite imagery, which is capable of collecting more than one million acres (5,000 km2) imagery in one go in just a few minutes. This allows for fast repeat imaging when necessary, and minimizes the risk of double counting as it's so rapid.

Then the team leveraged deep learning to process the vast amount of imagery it collected from Maxar's WorldView-3 satellite. In a matter of hours, the team collected its relevant data. This process usually takes months when sorting out by hand. On top of speed, the deep learning algorithms also provided consistent results less prone to error, as well as false negatives and false positives. In order to develop this method, the team created a customized training dataset of over 1,000 elephants, and then fed it into a Convolutional Neural Network (CNN). After trials, the team concluded that its CNN can detect elephants in satellite imagery with as high an accuracy as human detection capabilities.
