The Blurred Lines and Closed Loops of Google Search (wired.com) 15

Early this year, Google pushed out a seemingly tiny tweak to how it displays search ads for desktop computers. From a report: Previously, the search engine had marked paid results with the word "Ad" in a green box, tucked beneath the headline next to a matching green display URL. Now, all of a sudden, the "Ad" and the URL shifted above the headline, and both were rendered in discreet black; the box disappeared. The organic search results underwent a similar makeover, only with a new favicon next to the URL instead of the word "Ad." The result was a general smoothing: Ads looked like not-ads. Not-ads looked like ads. This was not Google's first time fiddling with the search results interface. In fact, it had done so quite regularly over the last 13 years, as handily laid out in a timeline from the news site Search Engine Land. Each iteration whittled away the distinction between paid and unpaid content that much more. Most changes went relatively unnoticed, internet residents accepting the creep like the apocryphal frog in a slowly boiling pot.

But in January, amid rising antitrust drumbeats and general exhaustion with Big Tech, people noticed. Interface designers, marketers, and Google users alike decried the change, saying it made paid results practically indistinguishable from those that Google's search algorithm served up organically. The phrase that came up most often: "dark pattern," a blanket term coined by UX specialist Harry Brignull to describe manipulative design elements that benefit companies over their users. That a small design tweak could inspire so much backlash speaks to the profound influence Google and other ubiquitous platforms have -- and the responsibility that status confers to them. "Google and Facebook shape realities," says Kat Zhou, a product designer who has created a framework and toolkit to help promote ethical design. "Students and professors turn to Google for their research. Folks turn to Facebook for political news. Communities turn to Google for Covid-19 updates. In some sense, Google and Facebook have become arbiters of the truth. That's particularly scary when you factor in their business models, which often incentivize blurring the line between news and advertisements."

Google's not the only search engine to blur this line. If anything, Bing is even more opaque, sneaking the "Ad" disclosure under the header, with only a faint outline to draw attention. [...] But Google has around 92 percent of global search marketshare. It effectively is online search. Dark patterns are all too common online in general, and January wasn't the first time people accused Google of deploying them. In June of 2018, a blistering report from the Norwegian Consumer Council found that Google and Facebook both used specific interface choices to strip away user privacy at almost every turn. The study details how both platforms implemented the least privacy-friendly options by default, consistently "nudged" users toward giving away more of their data, and more. It paints a portrait of a system designed to befuddle users into complacency. [...] That confusion reached its apex a few months later, when an Associated Press investigation found that disabling Location History on your smartphone did not, in fact, stop Google from collecting your location in all instances.

Google Images Launches 'Licensable' Badge and Search Filter (petapixel.com) 5

Google today launched new features in Google Images "to help people use images on the web responsibly." From a report: The features should benefit photographers, as they help people both identify photos that can be licensed as well as find out how to properly license them. Google Images' new "Licensable" badge, which had been in beta testing since February 2020, is now live. "[W]ith a seemingly infinite number of images online, finding the right image to use, and knowing how to use that image responsibly, isn't always a simple task," Google says. Google's new Licensable badge aims to make it easier for photo buyers to find photos they can license. Whenever a publisher or photographer provides licensing information for a photo (by providing structured data or IPTC photo metadata), Google will display a badge that says "Licensable" over the photo in search results.

Apple Mistakenly Approved a Widely Used Malware To Run on Macs (techcrunch.com) 44

Apple has some of the strictest rules to prevent malicious software from landing in its app store, even if on occasion a bad app slips through the net. But last year Apple took its toughest approach yet by requiring developers to submit their apps for security checks in order to run on millions of Macs unhindered. From a report: The process, which Apple calls "notarization," scans an app for security issues and malicious content. If approved, the Mac's in-built security screening software, Gatekeeper, allows the app to run. Apps that don't pass the security sniff test are denied, and are blocked from running. But security researchers say they have found the first Mac malware inadvertently notarized by Apple. Peter Dantini, working with Patrick Wardle, a well-known Mac security researcher, found a malware campaign disguised as an Adobe Flash installer. These campaigns are common and have been around for years -- even if Flash is rarely used these days -- and most run unnotarized code, which Macs block immediately when opened. But Dantini and Wardle found that one malicious Flash installer had code notarized by Apple and would run on Macs. Wardle confirmed that Apple had approved code used by the popular Shlayer malware, which security firm Kaspersky said is the "most common threat" that Macs faced in 2019.

CenturyLink Outage Led To a 3.5% Drop in Global Web Traffic (zdnet.com) 27

US internet service provider CenturyLink has suffered a major technical outage on Sunday after a misconfiguration in one of its data centers created havoc all over the internet. From a report Due to the technical nature of the outage -- involving both firewall and BGP routing -- the error spread outward from CenturyLink's network and also impacted other internet service providers, ending up causing connectivity problems for many more other companies. The list of tech giants who had services go down today because of the CenturyLink outage includes big names like Amazon, Twitter, Microsoft (Xbox Live), EA, Blizzard, Steam, Discord, Reddit, Hulu, Duo Security, Imperva, NameCheap, OpenDNS, and many more. Cloudflare, which was also severely impacted today, said CenturyLink's outward-propagating issue led to a 3.5% drop in global internet traffic, which would make this one of the biggest internet outages ever recorded.

Amazon Wins FAA Approval For Prime Air Drone Delivery Fleet (cnbc.com) 48

Amazon received federal approval to operate its fleet of Prime Air delivery drones, a milestone that allows it to expand unmanned package delivery, the Federal Aviation Administration said Monday. From a report: The approval will give Amazon broad privileges to "safely and efficiently deliver packages to customers," the FAA said. The FAA certification comes under Part 135 of FAA regulations, which gives Amazon the ability to carry property on small drones "beyond the visual line of sight" of the operator. Amazon said it will use the FAA's certification to begin testing customer deliveries. The company said it went through rigorous training and submitted detailed evidence that its drone delivery operations are safe, including demonstrating the technology for FAA inspectors. "This certification is an important step forward for Prime Air and indicates the FAA's confidence in Amazon's operating and safety procedures for an autonomous drone delivery service that will one day deliver packages to our customers around the world" David Carbon, vice president of Prime Air, said in a statement. "We will continue to develop and refine our technology to fully integrate delivery drones into the airspace, and work closely with the FAA and other regulators around the world to realize our vision of 30 minute delivery."

For U.S. Space Force Ranks, William Shatner Endorses 'Starfleet Amendment' (spacenews.com) 207

America's House of Representatives proposed a new structure for the U.S. Space Force in what's being called "the Starfleet amendment". Space News reports: Before the House passed the so-called "Starfleet" amendment, Space Force officials had been internally debating a new rank structure to set the space branch apart from its parent service the U.S. Air Force. The amendment in the House version of the 2021 National Defense Authorization Act requires the Space Force to use the Navy's rank structure. The proposal will be debated later this year in a House and Senate conference. The Senate would have to support the amendment for it to become law.
The amendment was introduced by a former Navy SEAL (now a Republican congressman from Texas), the article reports. But more importantly, the amendment "got a prominent endorsement from the Starfleet captain himself, William Shatner." In a special editorial in Military Times, Shatner wrote: It's been captains throughout entertainment history that have gone into space and been the heroes that saved the day, the planet, the galaxy and the universe. Where in any of this rich history of inspired heroes travelling into space was there a...colonel...?

"Star Trek" has borrowed so much of its iconic rank symbols from the U.S. military and NASA. When you unveiled the Space Force logo, many immediately saw it as an homage to "Star Trek" (even though our Delta was an homage to the previous military space insignias). Why not borrow back from "Star Trek" and adopt our ranks as well? We took them from the Navy for good reason, even though Gene Roddenberry was a veteran of the U.S. Army Air Corps. They made better sense when talking about a (space) ship.

So wrapping this up, I'm going to say that if you want the public to believe in heroes, that you should adopt the Navy ranks as they are the ones the public is most used to being heroes. So please reconsider and name the Space Force ranks after the U.S. Navy.

Space News reports that officials from Space Force "declined to comment on Shatner's article, or on whether his views might carry any weight with lawmakers." But the site's source said there's polarized feelings inside real-world Space Force about the Starfleet amendment.

"Some view the prospect of using naval ranks as an insult that would permanently turn the service into a Star Trek punchline."

Manned Flying Car Successfully Tested for the First Time (cnn.com) 110

The Japanese company SkyDrive "has announced the successful test drive of a flying car," reports CNN: It was the first public demonstration for a flying car in Japanese history. The car, named SD-03, manned with a pilot, took off and circled the field for about four minutes... "We want to realize a society where flying cars are an accessible and convenient means of transportation in the skies and people are able to experience a safe, secure, and comfortable new way of life," CEO Tomohiro Fukuzawa said in a statement.

The SD-03 is the world's smallest electric vertical takeoff and landing vehicle and takes up the space of about two parked cars, according to the company. It has eight motors to ensure "safety in emergency situations..." The success of this flight means that it is likely the car will be tested outside of the Toyota Test field by the end of the year. The company will continue to develop technologies to safely and securely launch the flying car in 2023, the news release said.

No price has been announced.

Are Apple's Privacy Changes Hypocritical, Unfair to Facebook and Advertising Companies? (chron.com) 168

iPhone users will have to opt-in to tracking starting with iOS 14. Advertisers are "crying foul," reports the Washington Post: [W]ith Apple under the antitrust spotlight, its privacy move has also been called a power move by an advertising industry that is scrambling to adjust to the changes, expected to be included in iOS 14, the company's latest mobile operating system expected to go live next month... "This is not a change we want to make, but unfortunately Apple's updates to iOS14 have forced this decision," Facebook said in a blog post.

Some in the advertising industry see the moves as part privacy, part self-interest on the part of Apple. Apple also offers advertising, and by limiting the amount of data outside marketers collect, Apple's access to the data becomes more valuable. "I think there's probably 30 percent truth in that they're doing it for privacy reasons and it's 70 percent that they're doing it because it's what's good for Apple," said Nick Jordan, founder of Narrative I/O, which helps companies gather data for advertising. "It's a question for regulators and courts whether they should be able to wield the power they do over this ecosystem," he said. "They created it, but can they rule it with an iron fist...?"

Apple says that when customers open apps, they'll be asked whether they'd like to give that specific app permission to track them with something called an "ID for Advertisers," or IDFA. Apple created the IDFA in 2012 to help app developers earn money on iOS. The unique number, assigned to iPhone customers, allows advertisers to track their movements around websites and apps by following that unique identifier... With the new pop-up messages, customers will be forced to make a choice. It is likely that most consumers will opt out of being tracked. Facebook said in a blog post that it would render its off-platform ad network so ineffective that it may not make sense to offer it to developers at all. Facebook said that in testing it had seen a more than 50% drop in revenue as a result of the loss of data from Apple...

"There's been no discussion, no commercial transaction. They're saying this is what we decided is right in the name of privacy and this is what we're going to do," said Stuart Ingis, a partner at the law firm Venable who represents the Partnership for Responsible Addressable Media, an association of advertisers.

"Personally, I don't see the problem here," argues Slashdot reader JustAnotherOldGuy.

The Post notes that Apple runs its own advertising business based on data gathered from its users — but Apple's director of privacy engineering "doesn't consider this data gathering 'tracking'...because Apple collects the data from its own users on its own apps and other services. Facebook and other advertisers, Apple says, gather data on users even when they're not using Facebook."

ARM Not Just For Macs: Might Make Weather Forecasting Cheaper Too (nag.com) 41

An anonymous reader writes: The fact that Apple is moving away from Intel to ARM has been making a lot of headlines recently — but that's not the only new place where ARM CPUs have been making a splash.

ARM has also been turning heads in High Performance Computing (HPC), and an ARM-based system is now the world's most powerful supercomputer (Fugaku). AWS recently made their 2nd generation ARM Graviton chips available which allows everyone to test HPC workloads on ARM silicon. A company called The Numerical Algorithms Group recently published a small benchmark study that compared weather simulations on Intel, AMD and ARM instances on AWS and reported that although the ARM silicon is slowest, it is also the cheapest for this benchmark.

The benchmark test concludes the ARM processor provides "a very cost-efficient solution...and performance is competitive to other, more traditional HPC processors."

Facebook Ignored 455 Complaints About Militia Page Urging Weapons at Kenosha Protest (buzzfeednews.com) 432

BuzzFeed News reports: In a companywide meeting on Thursday, Facebook CEO Mark Zuckerberg said that a militia page advocating for followers to bring weapons to an upcoming protest in Kenosha, Wisconsin, remained on the platform because of "an operational mistake." The page and an associated event inspired widespread criticism of the company after a 17-year-old suspect allegedly shot and killed two protesters Tuesday night.

The event associated with the Kenosha Guard page, however, was flagged to Facebook at least 455 times after its creation, according to an internal report viewed by BuzzFeed News, and had been cleared by four moderators, all of whom deemed it "non-violating." The page and event were eventually removed from the platform on Wednesday — several hours after the shooting.

"To put that number into perspective, it made up 66% of all event reports that day," one Facebook worker wrote in the internal "Violence and Incitement Working Group" to illustrate the number of complaints the company had received about the event... The internal report seen by BuzzFeed News reveals the extent to which concerned Facebook users went to warn the company of a group calling for public violence, and how the company failed to act.

After BuzzFeed news published its story about Facebook's internal report, Mark Zuckerberg made the same comments in a public forum, reports CNN: The page clearly violated Facebook's rules against violent militias, Zuckerberg acknowledged in a video posted Friday to his Facebook profile, and that "a bunch of people" had even reported the page prior to the killing of two protesters, Joseph Rosenbaum and Anthony Huber.

Just last week, Facebook announced it would crack down on militia organizations that advocated for violence or spoke about the potential for violence. But in its first week of implementation, the policy's lack of enforcement led to the spread of violent messages on the platform directly linked to the events in Kenosha, where protests erupted after the police shooting of Jacob Blake.

Cory Doctorow's New Book Explains 'How to Destroy Surveillance Capitalism' (medium.com) 76

Blogger/science fiction writer Cory Doctorow (also a former EFF staffer and activist) has just published How to Destroy Surveillance Capitalism — a new book which he's publishing free online.

In a world swamped with misinformation and monopolies, Doctorow says he's knows what's missing from our proposed solutions: If we're going to break Big Tech's death grip on our digital lives, we're going to have to fight monopolies. That may sound pretty mundane and old-fashioned, something out of the New Deal era, while ending the use of automated behavioral modification feels like the plotline of a really cool cyberpunk novel... But trustbusters once strode the nation, brandishing law books, terrorizing robber barons, and shattering the illusion of monopolies' all-powerful grip on our society. The trustbusting era could not begin until we found the political will — until the people convinced politicians they'd have their backs when they went up against the richest, most powerful men in the world. Could we find that political will again...?

That's the good news: With a little bit of work and a little bit of coalition building, we have more than enough political will to break up Big Tech and every other concentrated industry besides. First we take Facebook, then we take AT&T/WarnerMedia. But here's the bad news: Much of what we're doing to tame Big Tech instead of breaking up the big companies also forecloses on the possibility of breaking them up later... Allowing the platforms to grow to their present size has given them a dominance that is nearly insurmountable — deputizing them with public duties to redress the pathologies created by their size makes it virtually impossible to reduce that size. Lather, rinse, repeat: If the platforms don't get smaller, they will get larger, and as they get larger, they will create more problems, which will give rise to more public duties for the companies, which will make them bigger still.

We can work to fix the internet by breaking up Big Tech and depriving them of monopoly profits, or we can work to fix Big Tech by making them spend their monopoly profits on governance. But we can't do both. We have to choose between a vibrant, open internet or a dominated, monopolized internet commanded by Big Tech giants that we struggle with constantly to get them to behave themselves...

Big Tech wired together a planetary, species-wide nervous system that, with the proper reforms and course corrections, is capable of seeing us through the existential challenge of our species and planet. Now it's up to us to seize the means of computation, putting that electronic nervous system under democratic, accountable control.

With "free, fair, and open tech" we could then tackle our other urgent problems "from climate change to social change" — all with collective action, Doctorow argues. And "The internet is how we will recruit people to fight those fights, and how we will coordinate their labor.

"Tech is not a substitute for democratic accountability, the rule of law, fairness, or stability — but it's a means to achieve these things."

Brave Complains Google's Newly-Proposed 'WebBundles' Standard Would 'Make URLs Meaningless' (brave.com) 169

"Google is proposing a new standard called WebBundles," complains Brave's senior privacy reseacher. "This standard allows websites to 'bundle' resources together, and will make it impossible for browsers to reason about sub-resources by URL." This threatens to change the Web from a hyperlinked collection of resources (that can be audited, selectively fetched, or even replaced), to opaque all-or-nothing "blobs" (like PDFs or SWFs). Organizations, users, researchers and regulators who believe in an open, user-serving, transparent Web should oppose this standard...

The Web is valuable because it's user-centric, user-controllable, user-editable. Users, with only a small amount of expertise, can see what web-resources a page includes, and decide which, if any, their browser should load; and non-expert users can take advantage of this knowledge by installing extensions or privacy protecting tools... At root, what makes the Web different, more open, more user-centric than other application systems, is the URL. Because URLs (generally) point to one thing, researchers and activists can measure, analyze and reason about those URLs in advance; other users can then use this information to make decisions about whether, and in what way, they'd like to load the thing the URL points to...

At a high level, WebBundles are a way of packing resources together, so that instead of downloading each Website, image and JavaScript file independently, your browser downloads just one "bundle", and that file includes all the information needed to load the entire page. And URLs are no longer common, global references to resources on the Web, but arbitrary indexes into the bundle. Put differently, WebBundles make Websites behave like PDFs (or Flash SWFs). A PDF includes all the images, videos, and scripts needed to render the PDF; you don't download each item individually. This has some convenience benefits, but also makes it near-impossible to reason about an image in a PDF independently from the PDF itself. This is, for example, why there are no content-blocking tools for PDFs. PDFs are effectively all or nothing propositions, and WebBundles would turn Websites into the same.

By changing URLs from meaningful, global identifiers into arbitrary, package-relative indexes, WebBundles give advertisers and trackers enormously powerful new ways to evade privacy and security protecting web tools... At root, the common cause of all these evasions is that WebBundles create a local namespace for resources, independent of what the rest of the world sees, and that this can cause all sorts of name confusion, undoing years of privacy-and-security-improving work by privacy activists and researchers...

We've tried to work at length with the WebBundle authors to address these concerns, with no success. We strongly encourage Google and the WebBundle group to pause development on this proposal until the privacy and security issues discussed in this post have been addressed. We also encourage others in the Web privacy and security community to engage in the conversation too, and to not implement the spec until these concerns have been resolved.

'Unusually Large Number' of Breached SendGrid Accounts Are Sending Spams and Scams (krebsonsecurity.com) 13

Krebs on Security reports: Email service provider Sendgrid is grappling with an unusually large number of customer accounts whose passwords have been cracked, sold to spammers, and abused for sending phishing and email malware attacks. Sendgrid's parent company Twilio says it is working on a plan to require multi-factor authentication for all of its customers, but that solution may not come fast enough for organizations having trouble dealing with the fallout in the meantime...

[A] large number of organizations allow email from Sendgrid's systems to sail through their spam-filtering systems. To make matters worse, links included in emails sent through Sendgrid are obfuscated (mainly for tracking deliverability and other metrics), so it is not immediately clear to recipients where on the Internet they will be taken when they click...

Rob McEwen is CEO of Invaluement.com, an anti-spam firm whose data on junk email trends are used to improve the spam-blocking technologies deployed by several Fortune 100 companies. McEwen said no other email service provider has come close to generating the volume of spam that's been emanating from Sendgrid accounts lately. "As far as the nasty criminal phishes and viruses, I think there's not even a close second in terms of how bad it's been with Sendgrid over the past few months," he said...

Neil Schwartzman, executive director of the anti-spam group CAUCE, said Sendgrid's two-factor authentication plans are long overdue, noting that the company bought Authy back in 2015. "Single-factor authentication for a company like this in 2020 is just ludicrous given the potential damage and malicious content we're seeing," Schwartzman said... Schwartzman said if Twilio doesn't act quickly enough to fix the problem on its end, the major email providers of the world (think Google, Microsoft and Apple) — and their various machine-learning anti-spam algorithms — may do it for them.

Krebs found an online cybercriminal selling access to more than 400 compromised Sendgrid accounts. "Accounts that can send up to 40,000 emails a month go for $15, whereas those capable of blasting 10 million missives a month sell for $400."

'The Largest Nuclear Bomb Ever Detonated' Explored in Declassified Russian Footage (smithsonianmag.com) 210

"The blast was over 3,000 times bigger than the bomb that destroyed Hiroshima," reports Smithsonian magazine: Hydrogen bombs are so destructive, their impact has been described as unthinkable throughout history. Recently declassified Russian footage of the 1961 Tsar Bomba hydrogen bomb test shows why. The 40-minute documentary, which was posted on YouTube on August 20, shows footage of the largest bomb ever detonated on Earth, Thomas Nilsen reports for the Barents Observer.

Video footage shows the blast from several angles, sometimes struggling to show the entire mushroom cloud in the frame. Later, the documentary compares the ice-covered archipelago before the blast to the scorched, red and brown landscape left behind afterward. The Soviet Union tested the 50-million-ton hydrogen bomb, officially named RDS-220 and nicknamed Tsar Bomba, in late October 1961, Matthew Gault reports for Vice. This test occured during the height of the Cold War, when the Soviet Union and the United States competed to build the largest and most destructive nuclear weapons.

"There was a megatonnage race — who was going to have a bigger bomb," atomic age historian Robert S. Norris tells the New York Times' William Broad. "And the Soviets won...." It was three times as large as the biggest bomb ever detonated by the U.S., dubbed Castle Bravo.

schwit1 shares more information from Popular Mechanics: It's difficult to truly get across how powerful RDS-220 was. The mushroom cloud reached an altitude of 210,000 feet, and people observed the flash through bad weather at 621 miles. An observer felt heat from the explosion at a distance of 168 miles, and the bomb was capable of inflicting third-degree burns at 62 miles.

To Assuage Fears of Google Domination, Istio Restructures Its Steering Committee (thenewstack.io) 10

An anonymous reader quotes The New Stack: While there are some who may never get over the fact that the Istio service mesh, originally created by Google and IBM, will not be handed over to the Cloud Native Computing Foundation, the project took a big step this past week to assuage those who critiqued the project for being under a Google-majority control: Istio has introduced a new Istio steering committee.

According to the blog post, the new steering committee will consist of 13 seats, with four "elected Community Seats" and nine "proportionally allocated Contribution Seats," a change they say "solidifies our commitment to open governance, ensuring that the community around the project will always be able to steer its direction, and that no one company has majority voting control over the project." This final point is really the key to the announcement here, with them further and more explicitly clarifying later that "no single vendor, no matter how large their contribution, has majority voting control over the Istio project." To this end, they write, they have "implemented a cap on the number of seats a company can hold, such that they can neither unanimously win a vote, or veto a decision of the rest of the committee."

As for how those seats are allocated, the four Community Seats will consist of four representatives from four different organizations and will be chosen in an annual election. The nine Contribution Seats will be assigned to a minimum of three different companies "in proportion to contributions made to Istio in the previous 12 months," with this year's metric being merged pull requests.

But not everyone was satisfied. On Twitter AWS engineer Matthew S. Wilson called it "a crappy way to build a community," objecting to the way it's recognizing and rewarding open source contributions by company rather than by the individuals.

And Knative co-founder Matt Moore called it "what you get when a company wants to 'play community', but treat its employees as interchangeable cogs."

Thin-Skinned Solar Panels Printed With Inkjet (phys.org) 28

An anonymous reader quotes a report from Phys.Org: Solar cells can now be made so thin, light and flexible that they can rest on a soap bubble. The new cells, which efficiently capture energy from light, could offer an alternative way to power novel electronic devices, such as medical skin patches, where conventional energy sources are unsuitable. Until now, ultrathin organic solar cells were typically made by spin-coating or thermal evaporation, which are not scalable and which limit device geometry. This technique involved using a transparent and conductive, but brittle and inflexible, material called indium tin oxide (ITO) as an electrode. To overcome these limitations, the team applied inkjet printing. "We formulated functional inks for each the layer of the solar cell architecture," says Daniel Corzo, a Ph.D. student in Baran's team.

Instead of ITO, the team printed a transparent, flexible, conductive polymer called PEDOT:PSS, or poly(3,4-ethylenedioxythiophene) polystyrene sulfonate. The electrode layers sandwiched a light-capturing organic photovoltaic material. The whole device could be sealed within parylene, a flexible, waterproof, biocompatible protective coating. [...] After optimizing the ink composition for each layer of the device, the solar cells were printed onto glass to test their performance. They achieved a power conversion efficiency (PCE) of 4.73 percent, beating the previous record of 4.1 percent for a fully printed cell. For the first time, the team also showed that they could print a cell onto an ultrathin flexible substrate, reaching a PCE of 3.6 percent.
The research has been published in the journal Advanced Materials Technologies.

A Closer Look At Elon Musk's Neuralink Surgical Robot (techcrunch.com) 44

Earlier today, Elon Musk demonstrated his startup Neuralink's brain link device working in a pig named Gertrude. While the science and the device itself were front-and-center at the presentation, the surgical robot the company debuted is equally as important because it's designed to handle the full surgical installation process. "That includes opening up the scalp, removing a portion of the skull, inserting the hundreds of 'thread' electrodes 6mm deep along with the accompanying chip, then closing the incision," reports CNET. TechCrunch takes a closer look at the robot: The rounded polycarbonate sci-fi design of the brain surgeon bot looks like something out of the Portal franchise, but it's actually the creation of Vancouver-based industrial design firm Woke Studio. To be clear, Musk's engineers and scientists have created the underlying technology, but Woke built the robot's look and user experience, as well as the behind-the-ear communication end piece that Neuralink has shown in prior presentations. Neuralink's bot features clean white (required for ensuring sterility, per Woke), arcing lines and smooth surfaces for a look that at once flags its advanced technical capabilities, but also contains some soothing and more approachable elements, which is wise considering what the machine is intended to do.

Woke says the Neuralink surgical robot can be separated into three main parts: The head, the body and base. The head of the robot is that helmet-like piece, which actually holds the head of the patient. It also includes a guide for the surgical needle, as well as embedded cameras and sensors to map the patent's brain. The intent of the design of this piece, which includes a mint-colored interior, is to give the robot "an anthroprmorphic characteristic" that helps distract from the invasive nature of the procedure. There are also single-use disposable bags that line the interior of the helmet for sterile operation. The Neuralink robot also has a "body," that humped rear assembly, which includes all the parts responsible for the motion of the robot as it sets up from the procedure. The third element is the base, which basically keeps the whole thing from tipping over, and apparently also contains the computing brains of the brain-bot itself.

Long-Awaited Celera 500L 'Bullet' Plane Is Finally Revealed (cnn.com) 65

The Grim Reefer shares a report from CNN: The whispers started three years ago. A mysterious bullet-shaped plane was spotted at the Southern California Logistics Airport near Victorville in April 2017. Its unusual design prompted immediate speculation, with military website The War Zone being the first to report that the aircraft was the work of California-based Otto Aviation -- and that development was very much under wraps.

Now, in the late summer of the strangest year in aviation history, the Celera 500L has finally been revealed to the world, with the launch of a new website and a bunch of very cool new photos. What we're looking at is a six-person private craft that promises to fly at jet speeds, but with eight times lower fuel consumption, and a range that's twice that of a comparably sized craft. Bold claims indeed. Otto Aviation says on its website that 31 successful test flights have so far been performed, with aerodynamic efficiency proven in 2019, bolstering its declaration that "the Celera 500L is the most fuel-efficient, commercially viable aircraft in existence."

Elon Musk Shows Neuralink Brain Link Working In a Pig (cnet.com) 87

With a pig named Gertrude, Elon Musk demonstrated his startup Neuralink's technology to build a digital link between brains and computers. A wireless link from the Neuralink device showed the pig's activity activity as it snuffled around a pen on stage Friday night. CNET reports: The demonstration shows the the technology to be significantly closer to delivering on Musk's radical ambitions than during a 2019 product debut, when Neuralink only showed photos of a rat with a Neuralink connected via a USB-C port. It's still far from reality, but Musk said the US Food and Drug Administration in July granted approval for "breakthrough device" testing. Musk also showed a second-generation device that's more compact and that fits into a small cavity hollowed out of a hole in a skull. "It's like a Fitbit in your skull with tiny wires," Musk said of the device. It communicates with brain cells with 1,024 thin electrodes that penetrate within brain cell.
