Scientists combed through nearly 30 years of earthquake data to probe huge and mysterious objects near the Earth's core. From a report: Scientists have discovered a vast structure made of dense material occupying the boundary between Earth's liquid outer core and the lower mantle, a zone some 3,000 kilometers (1,864 miles) beneath our feet. The researchers used a machine learning algorithm that was originally developed to analyze distant galaxies to probe the mysterious phenomenon occurring deep within our own planet, according to a paper published on Thursday in Science. One of these enormous anomalies, located deep under the Marquesas Islands, had never been detected before, while another structure beneath Hawaii was found to be much larger than previously estimated. Scientists led by Doyeon Kim, a seismologist and postdoctoral fellow at the University of Maryland, fed seismograms captured from hundreds of earthquakes that occurred between 1990 to 2018 into an algorithm called Sequencer. While seismological studies tend to focus on relatively small datasets of regional earthquake activity, Sequencer allowed Kim and his colleagues to analyze 7,000 measurements of earthquakes -- each with a magnitude of at least 6.5 -- that shook the subterranean world under the Pacific Ocean within the past three decades. "This study is very special because, for the first time, we get to systematically look at such a large dataset that actually covers more or less the entire Pacific basin," Kim said in a call. Though scientists have previously mapped out structures deep inside Earth, this study presents a rare opportunity to "bring everything in together and try to explain it in a global context," he noted.

Homeowners and pool operators are turning to artificial intelligence for an extra layer of safety to prevent drownings in backyard and public pools. From a report: The detection systems, which use submerged cameras and a form of AI known as computer vision, analyze live videos of swimmers and send alerts if they spot a person who appears to be drowning. Jenny Naggatz, 33, of Gulf Breeze, Fla., installed an AI device from technology company Coral Detection Systems in her family's pool to safeguard her two children, both of whom are under 4. Coral Detection's triangle-shaped device sits in the corner of a pool with an attached camera hanging a few inches below the water surface. "It has definitely given me more peace of mind," Ms. Naggatz said. "I'm just as careful around the water as I would be without it, but it's just another layer of protection." The safety of young children around swimming pools remains a cause for concern, according to a U.S. Consumer Product Safety Commission report released last week. On average, 379 children under 15 drowned each year in pools, spas or hot tubs from 2015 through 2017, the most recent statistics available, and hit a peak of 395 in 2017, the commission said. Noting that most child drownings occur at home during the summer months, the commission urged caution given that Covid-19 measures had confined more families to their homes and delayed the opening of public pools. AI drowning-detection products are not intended to replace adult supervision or lifeguards, but rather to serve as an extra safeguard.

The problem with snake oil pitches like The Correspondent, aside from the fact that they're dishonest, is that they suck resources away from ideas that might actually make news work better. This happened repeatedly in tech. A famous successful tech entrepreneur claims to have found a breakthrough, and the press gets all excited. It sucks up all the money and attention that might have gone to products that could have helped, and then they do it again and again. People should be suspicious of grand claims, no matter who is making them. And if you, an analyst, really think you've found The One, you should get opinions from friends before you stake your rep on it.

Twitter btw is quite fluid. That's one of the things I like most about it. But it has severe limits on what it can do.

The other day I wrote a short definition of blogging, including a word I suspect not a lot of bloggers would use -- fluid. To me the process of writing on your blog, if it isn't fluid, it isn't doing its job. By fluid I mean this. I have an idea. Count the steps before the idea appears on your blog and how complex the steps are. The more steps the more likely you'll lose your way, and find it hard to get back to what you were doing. You respond by skipping it altogether, the idea is lost. You can engineer fluidity, the same way you can optimize for other attributes. But most blogging software doesn't imho even try.

Detections rates for stalkerware applications on Android and Windows devices are slowly improving, according to the findings of a seven-month research project carried out by independent antivirus testing lab AV-Comparatives and the Electronic Frontier Foundation. From a report: The study, published earlier this week, took place in two phases, with the first in November 2019, and the second in May 2020. Researchers looked at how 10 Android mobile antivirus apps and 10 Windows antivirus products detected some of today's most prevalent stalkerware strains. The stalkerware strains, 20 on Android and 10 on Windows, were chosen by AV-Comparatives together with the Electronic Frontier Foundation (EFF), based on their popularity in the US. The study discovered that many antivirus companies have improved their detection rates between the November 2019 scan and May 2020.

Republican Federal Communications Commissioner Mike O'Rielly said he's unsure whether his agency has the authority to carry out President Trump's executive order targeting tech firms' legal protections. From a report: Trump's order seeks to have the FCC craft regulations limiting the scope of legal immunity that online platforms have under federal law. All three commission Republicans would need to support such regulations for them to pass, as the FCC's two Democrats are certain to oppose them. In an interview Wednesday for C-SPAN's "The Communicators," O'Rielly told Axios he sympathizes with the president's claims that conservatives have been unfairly stifled online, but "what we do about that is a different story. I have deep reservations they provided any intentional authority for this matter, but I want to listen to people," O'Rielly said, later adding, "I do not believe it is the right of the agency to read into the statute authority that is not there."

The New York attorney general's office has interviewed Amazon workers from a handful of facilities in the state, as claims of employee retaliation become a central focus of its investigation into the company's labor practices, CNBC reported Friday, citing people familiar with the matter. From the report: New York Attorney General Letitia James sent a letter to Amazon in April saying it was looking into whether the company violated federal employment law or broke the state's whistleblower laws when it fired a worker who organized a strike at its Staten Island facility. The worker, Chris Smalls, led a protest calling for Amazon to close the warehouse and put in place greater safety protections, echoing warehouse workers' concerns across the country. The letter calls on Amazon to reinstate Smalls and asks it to turn over all internal communications dating back to Feb. 1 related to workers' complaints, protests and efforts to organize. In late March, James' office began contacting Amazon workers from New York area warehouses. So far, it has spoken to workers from facilities in Staten Island, Queens and Bethpage, and is adding more facilities to its roster as it receives complaints, the people said. The conversations have touched on Amazon's safety practices during the coronavirus pandemic, including enforcement of social distancing rules, workers' access to personal protective equipment and its documentation of positive coronavirus cases at facilities.

NASA has awarded Astrobotic of Pittsburgh $199.5 million to deliver NASA's Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon's South Pole in late 2023. From a report: The water-seeking mobile VIPER robot will help pave the way for astronaut missions to the lunar surface beginning in 2024 and will bring NASA a step closer to developing a sustainable, long-term presence on the Moon as part of the agency's Artemis program. "The VIPER rover and the commercial partnership that will deliver it to the Moon are a prime example of how the scientific community and U.S. industry are making NASA's lunar exploration vision a reality," said NASA Administrator Jim Bridenstine. "Commercial partners are changing the landscape of space exploration, and VIPER is going to be a big boost to our efforts to send the first woman and next man to the lunar surface in 2024 through the Artemis program." VIPER's flight to the Moon is part of NASA's Commercial Lunar Payload Services (CLPS) initiative, which leverages the capabilities of industry partners to quickly deliver scientific instruments and technology demonstrations to the Moon. As part of its award, Astrobotic is responsible for end-to-end services for delivery of VIPER, including integration with its Griffin lander, launch from Earth, and landing on the Moon.

Google escalated a fight with Sonos over the wireless home-speaker market, filing a lawsuit that alleges patent infringement. From a report: The conflict between the two companies, which had been collaborating on incorporating some Google features in Sonos's speakers, erupted in January when Sonos sued Google for infringing its patents. The speaker maker is facing increased competition from tech giants such as Google and Amazon.com that are expanding into selling Internet-connected home gadgets, including less expensive wireless speakers. "Sonos has made false claims about the companies' shared work and Google's technology in the lawsuits," the Alphabet unit said in a complaint filed Thursday in San Francisco federal court. "While Google rarely sues other companies for patent infringement, it must assert its intellectual property rights here." Sonos, the Santa Barbara-based pioneer of wireless speakers, is using Google's patented technology for search, software, networking, audio processing and digital-media management and streaming, while refusing to pay a license, according to the lawsuit.

I got an email from The Correspondent this morning, the first communication since they disappeared. I contributed $25 so I could find out what contributors got. Did it ever amount to anything? TheC didn't make sense, didn't come close to earning the universal acclaim it got, or the money they raised from the people. They claimed they would open a new kind of news org in America, and when they met their money-raising goal said that was never their intention.

During an internal presentation at Facebook on Wednesday, the company debuted features for Facebook Workplace, an intranet-style chat and office collaboration product similar to Slack. From a report: On Facebook Workplace, employees see a stream of content similar to a news feed, with automatically generated trending topics based on what people are posting about. One of the new tools debuted by Facebook allows administrators to remove and block certain trending topics among employees. The presentation discussed the "benefits" of "content control." And it offered one example of a topic employers might find it useful to blacklist: the word "unionize." Facebook Workplace is currently used by major employers such as Walmart, which is notorious for its active efforts to suppress labor organizing. The application is also used by the Singapore government, Discovery Communications, Starbucks, and Campbell Soup Corporation. The suggestion that Facebook is actively building tools designed to suppress labor organizing quickly caused a stir at the Menlo Park, California-based company. Facebook employees sparked a flurry of posts denouncing the feature, with several commenting in disbelief that the company would overtly pitch "unionize" as a topic to be blacklisted.
