Electronic skin will only truly become practical if it's thin enough to be virtually unnoticeable, and scientists might have just delivered that breakthrough. Stanford researchers have developed a new technique that produces "atomically-thin" transistors under 100 nanometers long. That's "several times" shorter than the previous best, according to the university. The team accomplished the feat by overcoming a longstanding hurdle in flexible tech. While '2D' semiconductors are the ideal, they require so much heat to make that they'd melt the flexible plastic. The new approach covers glass-coated silicon with a super-thin semiconductor film (molybdenum disulfide) overlayed with nano-patterened gold electrodes. This produces a film just three atoms thick using a temperature nearing 1,500F — the conventional plastic substrate would have deformed around 680F. Once the components have cooled, the team can apply the film to the substrate and take a few "additional fabrication steps" to create a whole structure about five microns thick, or a tenth the thickness of human hair. It's even ideal for low-power use, as it can handle high currents at low voltage. There's more work to be done. The researchers want to both refine the flexible tech and include wireless tech that would allow networking without bulky hardware. This also ignores the usual challenges with tech like this — the inventors would need to find a way to mass-produce these transistors at reasonable prices. If successful, though, this could lead to highly efficient e-skins, implants and other flexible devices that are almost imperceptible.All products recommended by Engadget are selected by our editorial team, independent of our parent company.

The facial recognition program used by nearly two dozen US states to to verify people seeking unemployment benefits is working inconsistently, leading to many people being denied benefits or having their applications put on hold, Motherboard reported. The identity verification service ID.me is intended to help reduce unemployment fraud, and uses biometric data and official documents to verify people. But according to Motherboard, some who have applied for unemployment have reported that ID.me has failed to identify them correctly, and that they have had difficulty reaching someone at ID.me to remedy the problem. ID.me didn’t immediately reply to a request for comment Saturday, but the company’s CEO Blake Hall told Motherboard in an email that the algorithms the company uses in its Face Match technology have “99.9% efficacy.” He added that user error may be to blame, and said the company was not aware of “eligible individuals” who couldn’t verity their identity with its software. With millions of people unemployed due to the coronavirus pandemic, state offices have dealt with a surge of claims over the past year. Some states reported a sharp rise in fraudulent claims last spring, and the Department of Labor reported (.pdf) in February that between March and October of last year it had identified more than $5 billion of potentially fraudulent unemployment payments. That’s far less than the $400 billion estimate Hall suggested to Motherboard and other media outlets.
Be careful about giving your WiFi network an unusual name — it might create serious headaches for any iPhone users in the household. BleepingComputer and AppleInsider say that security researcher Carl Shou has discovered a naming bug that 'breaks' WiFi on iOS devices. Give your network an SSID like "%p%s%s%s%s%n" and your iPhone will lose WiFi functionality. You can get it back by resetting your network settings (Settings > General > Reset > Reset Network Settings), but that's clearly a pain if you just wanted to avoid using cellular data. The cause isn't clear at this point, but BleepingComputer speculated that it might be a string formatting flaw. Simply put, iOS might confuse the % entries with programming commands and variables. Schou noted that he regularly uses names like this to mess with "poorly developed devices." He tested the bug with iOS 14.4.2, but it was still a problem as of iOS 14.6. We've asked Apple for comment. Character-related bugs aren't unheard of. A 2018 bug in iOS and macOS crashed apps using a single symbol. WiFi issues are rare, however, and this glitch would make it relatively easy for pranksters to (temporarily) wreck your phone using public hotspots. While it was already a good idea to avoid connecting to strange hotspots, you'll have a particularly good reason to resist that temptation while this bug exists. After joining my personal WiFi with the SSID “%p%s%s%s%s%n”, my iPhone permanently disabled it’s WiFi functionality. Neither rebooting nor changing SSID fixes it :~) pic.twitter.com/2eue90JFu3— Carl Schou (@vm_call) June 18, 2021 All products recommended by Engadget are selected by our editorial team, independent of our parent company.

Today, on Juneteenth, we recognize the efforts this nation still needs to put toward addressing structural racism and disparities, including in the world of tech. This week, HBCUvc, a nonprofit that aims to diversify the world of venture capital, launched a million-dollar fund. Founder Hadiyah Mujhid told me that the capital would provide nondilutive financing to overlooked founders, which they define as Black, Indigenous and LatinX entrepreneurs, replacing the traditional angel round. But she also admitted that supporting founders wasn’t the only primary goal. Instead, she explained to me the importance of what she defines as “teaching capital.” Similar to how teaching hospitals give aspiring doctors a way to practice and learn their craft before formally entering the field, the fund wants to do that for their some 230 aspiring investors that they already work with, many stemming from historically Black colleges and universities. Notably, nondilutive capital provides entrepreneurs with funding sans equity and a learning experience with lower stakes. There are a lot of organizations right now that are starting funds [with] the primary goal of supporting founders. And that’s a goal of ours, but we’re hoping to have a ripple effect of training and really providing on-ramps for the next best-in-class investors … and in order to do that, they have to have a training vehicle. While I’m not always a fan of rebranded names for capital, “teaching capital” is certainly a compelling framing. Track record is everything in this industry, and underrepresented folks often don’t have the benefit or privilege of access on their side — from a dollar or deals perspective. Scout programs have long existed to fill this gap, but I think that there is still a lacking of intentionality around who feels empowered to write an investment memo, ask questions and be new. This week, BLCK VC launched its scout program and Google for Startups launched a nondilutive financing instrument for Black founders, underscoring a growing focus in seeding diverse entrepreneurs. HBCUvc’s fund was announced nearly one year after it almost shut down due to a lack of capital. Mujhid explained how the unjust killing of George Floyd led to the biggest one-day donation in her nonprofit’s lifetime, which “changed the trajectory of programming.” She also said that a lot of interest was a knee-jerk reaction, urging people to view this work as a long-term commitment. Down the creative capital rabbit hole we go: In the rest of this newsletter, we’ll get into Waymo’s latest raise, the Nubank EC-1 and a Pittsburgh event that I can’t wait to nerd out about. Waymo gets way more Image Credits: Bryce Durbin Waymo, Alphabet’s self-driving arm, raised $2.5 billion in its second-ever institutional round. Investors include Alphabet, Andreessen Horowitz, AutoNation, Canada Pension Plan Investment Board, Fidelity Management & Research Company, Temasek and, of course, Tiger Global. Here’s what to know: Waymo is going external after some internal shuffling. The funding comes only months after CEO John Krafcik stepped down from his title after spending five years in that position. Last month, Waymo lost its CFO and head of partnerships. For more, here are my favorite recaps of TC Sessions: Mobility: The Nubank EC-1 Image Credits: Nigel Sussman Another week, another EC-1! Marcella McCarthy wrote about Nubank, a Brazillian credit card and banking fintech company that just last week raised at a $30 billion valuation. It’s one of the most valuable startups in the world, with over 40 million users. Here’s what to know: As McCarthy puts it in the piece, Nubank started by trying to solve a massive challenge: “How to rebuild the concept of a bank in a country where banking is widely hated, all while the incumbents heavily entrenched with the state worked to block every move.” Maybe, the story goes on to tell, it would start with California Street. Check out each installment of the series below: Around TC In May, thousands of you read my Duolingo EC-1, a deep dive into Pittsburgh’s favorite edtech unicorn.

A recent string of problems suggests facial recognition's reliability issues are hurting people in a moment of need. Motherboard reports that there are ongoing complaints about the ID.me facial recognition system at least 21 states use to verify people seeking unemployment benefits. People have gone weeks or months without benefits when the Face Match system doesn't verify their identities, and have sometimes had no luck getting help through a video chat system meant to solve these problems. ID.me chief Blake Hall blamed the problems on users rather than the technology. Face Match algorithms have "99.9% efficacy," he said, and there was "no relationship" between skin tone and recognition failures. Hall instead suggested that people weren't sharing selfies properly or otherwise weren't following instructions. Motherboard noted that at least some people have three attempts to pass the facial recognition check, though. The outlet also pointed out that the company's claims of national unemployment fraud costs have ballooned rapidly in just the past few months, from a reported $100 billion to $400 billion. While Hall attributed that to expanding "data points," he didn't say just how his firm calculated the damage. It's not clear just what the real fraud threat is, in other words. Whatever is happening with ID.me's technology, the incidents highlight one of the reasons federal and state governments hope to limit facial recognition. Even if privacy and security aren't issues, they don't appear to be reliable enough to avoid significant issues. That 99.9 percent success rate could still leave many people without benefits they're eligible to claim. Systems like this may need to be considerably more trustworthy to eliminate these headaches in the future.All products recommended by Engadget are selected by our editorial team, independent of our parent company.

The Max 10 just before landing at Boeing Field. Boeing Boeing's latest airliner completed its first flight when the company's 737 Max 10 landed at Boeing Field near Seattle on Friday afternoon. The 2.5-hour flight over Washington state begins the process for certifying the aircraft, which is scheduled to enter passenger service by 2023.In a statement, 737 Chief Pilot Capt. Jennifer Henderson said the 737 Max 10 performed beautifully: "The profile we flew allowed us to test the airplane's systems, flight controls and handling qualities, all of which checked out exactly as we expected." Editors' top picks Subscribe to CNET Now for the day's most interesting reviews, news stories and videos. The largest and fourth member of the 737 Max family, the Max 10 seats 204 people in a typical configuration and was built to compete with the Airbus A321neo. Like other Max versions, it brings a redesigned and roomier passenger cabin, quieter and cleaner engines and better fuel efficiency.The Max 10 first rolled out of Boeing's Renton, Washington, factory in November 2019, eight months after all Max aircraft were grounded worldwide following two crashes that killed a combined total of 346 people. Though the airplane has the MCAS flight control system that was blamed for the crashes, all Max 10s will have the repairs mandated by the Federal Aviation Administration when it lifted the grounding order in November.The successful flight comes as Boeing works to both restore public confidence in the Max and overcome criticism of how it and the FAA certified the first Max aircraft in 2016. Though some airlines canceled their MAX orders during the grounding, sales have begun to rebound and Boeing is finding owners for unsold planes. Boeing has almost 500 orders for the Max 10 from airlines such as United Airlines, Copa Airlines and Virgin Australia. First introduced in 1968, the 737 family still holds the record of the best-selling commercial aircraft in history, with more than 10,500 planes delivered to hundreds of airlines around the world.

This story is part of Amazon Prime Day 2021, CNET's guide on everything you need to know and how to make sure you get the best deal. Amazon Prime Day (June 21-22) always brings solid deals on tablets, but it's not a good idea to jump at the cheapest one you see. Here, we are keeping an eye on Kindle Fire tablets and iPads and Kindle Fire tablets, and here's what you should keep in mind for each brand:Apple's iPads often sell for a bit less than their list price, so long as you don't buy at the Apple Store proper, where the price is basically never cut. So you may see some decent discounts right now ($30 to $50, or even more), but we may also see better deals during upcoming Prime Day sales at Amazon and elsewhere.Amazon's Fire tablets nearly always get deep discounts across the board during Prime Day and Black Friday/Cyber Monday. Those two times of year are almost always the best time to buy. Amazon's Thursday press release confirmed a big Fire tablet deal, the HD 10 for $80. But that deal isn't starting until Monday (at the latest). What this all means is that you should wait until Prime Day to buy a tablet (especially a Fire), even though you may see some decent discounts right now. We'll continue to monitor Amazon as well as its competitors such as Best Buy, Target and Walmart -- all of which have announced Prime Day counter-sales -- for any price drops on these or other popular tablet brands. Early Prime Day iPad deals Scott Stein/CNET The eighth-gen iPad features a 10.2-inch display powered by the A12 chip. The 32GB model has a list price of $329, but it's down to $299 at Amazon. We saw it dip to $279 last year at Costco, and it's possible we'll see this baseline iPad drop during actual Prime Day or one of the counter-sales. Read our iPad 2020 review. Apple Apple's 10.9-inch iPad Air delivers a lot of what the iPad Pro does, but at a lower price. That great value earned it our Editors' Choice award last year, but the newer Pro raises the bar (albeit for more money). Read our iPad Air review. Early Prime Day Fire Tablet deals David Carnoy/CNET Amazon's Fire HD 10 is the biggest and most powerful tablet that the company offers, and it recently got better. The 2021 revision launched in April with more RAM, a 10% brighter screen and a slightly updated design. Like its 2019 predecessor, the new HD 10 starts at $150. The recharged Fire HD 10 Plus offers wireless charging, an extra gigabyte of RAM and a "soft touch, slate colored finish" for $30 more -- $180. Right now, if you buy two Fire HD 10 models, you'll get $75 taken off the top ($225, down from $300). The discount is applied at checkout. On Prime Day, individual prices will drop up to 50%, putting the model at a price worth waiting for ($80). The Fire HD 10 comes packed with benefits for Prime subscribers, making it easy for members to stream and download movies, TV shows and games. The Fire tablets don't use a pure version of Android, but instead Amazon's Android-based Fire operating system, and pulls apps from the Amazon App Store. You can still get apps from Google Play, but you'll have to install the store yourself -- meaning gaming enthusiasts have access to all of their favorite mobile games for an excellent gaming tablet experience.

This child-friendly version of the Fire HD 8 tablet adds a padded case, parental controls, a two-year warranty and a one-year subscription to Kids Plus (formerly known as FreeTime Unlimited), which normally costs $3 a month and gives you access to a bunch of kid-friendly content. It's not really suitable for remote learning, but it's a much more affordable option than giving a young child a full-on iPad. Other potential Prime Day tablet deals César Salza/CNET Price worth waiting for: Normally $90, this sold for $55 last November.The Fire HD 8 (8-inch screen) was updated in 2020 with a faster processor, USB-C charging, better Wi-Fi performance, 2GB of RAM (up from 1.5GB) and a bump from 16GB to 32GB of storage in the base model. Its HD screen is sharper than the entry-level Fire 7, but it's not nearly as sharp as iPad displays. The HD 8 Plus adds wireless charging and slightly better performance, thanks to 3GB of RAM. Read our Amazon Fire HD 8 (2020) review. David Carnoy/CNET Price worth waiting for: Normally $110, this sold for $75 last November.The Fire HD 8 Plus adds wireless charging and more RAM (3GB instead of 2GB), with performance that improves on the standard Fire HD 8. The tablet should charge just fine on most wireless charging pads. Read our Amazon Fire HD 8 Plus review. Sarah Tew/CNET Price worth waiting for: Normally $50, this sold for as low as $30 last November.Fair warning: We really think you should pay up for a Fire HD 8, which is a much better, faster tablet than the entry-level Fire 7. But at $40 or less, this non-HD 7-inch model is going to be tempting for a lot of folks. Sarah Tew/CNET Price worth waiting for: Normally $100, this dipped to $60 last November.This has all of the same extras as the HD 8 above, but it's the childproof version of the smaller, more affordable Amazon Fire 7. You're getting a 7-inch screen instead of 8, and a less robust processor. CNET Cheapskate Subscribe to our daily spotlight on the best tech deals on the web -- from phones to gadgets and more.
Deal Savings Price Show more (1 item) This story is part of Amazon Prime Day 2021, CNET's guide on everything you need to know and how to make sure you get the best deal. Amazon Prime Day 2021 kicks off on June 21, but there's already a host of excellent deals to be had. Here we're zeroing in on some early home security deals from Amazon brands Ring and Blink. Many of the discounts on Ring and Blink security cameras are currently expired, but if prior years' sale trends continue, we expect they may return for Prime Day next week, or even as early as Sunday. As always when discussing its products, it's worth noting that Ring has faced push-back for its relationships with local police departments across the US. But those policies are changing: Earlier this month the company announced it would stop sending requests for footage to Neighbors app users. Learn more about this evolving policy here. Ring has also recently required users to manually opt out of Amazon Sidewalk, a new program that shares a portion of users' bandwidth, which was disturbing to many. We'll be updating this page regularly throughout the month of June to make sure you have the most up-to-date information to guide your buying decisions. Note you need to be an Amazon Prime subscriber to see these savings. Ring deals available now Ring As its name suggests, the Ring Video Doorbell Elite is the Amazon company's most expensive smart doorbell. This refurbished model typically retails for $300 ($350 new), but is currently just $130. For your $170 in savings, you get a hardwired doorbell with a built-in camera. It features a flush-mount design and a power-over-Ethernet connection, and Amazon says it's "certified to look and work like new." Expired deals: May return for Prime Day Ring Save $125 on the Ring Spotlight Cam Battery bundled with a second-gen Amazon Echo Show 5. If you've been looking for an outdoor home security camera that doesn't require a power adapter to operate, the Ring Spotlight Cam Battery is a good option. Add in a second-gen Echo Show 5 and you can ask Alexa to show you a live feed of whatever's happening on your Ring cam in real-time. David Priest/CNET Save $55 if you get a Ring Video Doorbell Wired bundled with a third-gen Amazon Echo Dot. We really liked the Video Doorbell Wired in our testing -- it's a great hardwired video doorbell at a reasonable price. That price is even better now; it's actually less than you'd spend on its normal list price of $60 to get it bundled with an Echo Dot. If you don't want a third-gen Echo Dot bundled with the Ring Video Doorbell Wired, then this is your next best option. You can get the 1080p HD Video Doorbell Wired for $15 less than normal. It's a solid video doorbell that was already priced well, but this deal takes it under 50 bucks. Megan Wollerton/CNET If you want a Ring Video Doorbell Wired with a Ring Chime, this is the deal for you. Get the two products bundled together for $75 -- that's a $5 savings. The Ring Chime is a range extender, a doorbell chime and nightlight. Megan Wollerton/CNET Get the Blink Mini indoor home security camera for just $20 -- that's a savings of $15 off the regular price. For a basic indoor wired camera, the Blink Mini is a decent option, especially at this price. It has 1080p HD resolution, motion alerts, two-way talk and all of the other standard features you'd expect from a home security camera. Megan Wollerton/CNET The Blink Outdoor camera typically costs $100, but it's currently on sale for $60. It's a pretty good security camera that's weatherproof and battery-powered so you don't have to deal with power outlets. The price was decent at $100, but the $40 savings makes it an even better option if you're looking for a versatile outdoor camera. Unlike the last-gen Blink XT2, this model requires a Blink subscription for cloud storage. Bring your home up to speed with the latest on automation, security, utilities, networking and more.

Amazon Prime Day 2021 starts on Monday, but you can find early sales on the site as well as on Best Buy, Target and Walmart. So if you're looking to buy a device from Roku, which makes a lot of our favorite streamers, you can find some great deals right now.All of the below devices we've highlighted below are simple ways to upgrade older TVs with the latest streaming services. Some are at or near all-time low prices including a $10 discount on the Roku Express 4K Plus and $31 off of Roku's higher end streaming devices. We update this post as prices and availability of the deals fluctuate. Deals available now Sarah Tew/CNET The latest Roku is our new go-to streaming pick. This is the best way to deliver a full range of streaming channels (including plenty of free content) to any TV, up to and including 4K HDR picture quality on compatible televisions. And now it's 25% off -- the best price we've seen since it first went on sale a few months ago. Sarah Tew/CNET The 2020 Roku Ultra offers a significant upgrade over other Roku devices with both a remote finder and a wired Ethernet port. Picture quality is as good as ever with Dolby Vision support, and it's quicker than other Ultras too, thanks to its superfast processor.

Sarah Tew/CNET Although the Roku Express 4K Plus is our new favorite, the Roku Streaming Stick Plus 4K is still great. The two are basically identical aside from design, although the Express 4K Plus does support an optional Ethernet adapter. Both offer hundreds of apps, the excellent Roku interface and a robust, voice-control remote, as well as 4K HDR and Apple AirPlay. Read our Roku Streaming Stick Plus review. Expired deals: May return for Prime Day Roku This is a bare-bones Roku that can handle all your streaming needs. It isn't as fast as the Streaming Stick Plus and doesn't include Roku's more useful enhanced remote (which has a microphone for voice control and doesn't require you to point it directly at the TV). It also lacks 4K support and new features like AirPlay. It is, however, just $17 and should be fine for basic streaming. The SE is pretty much identical to the $25 Roku Express, aside from the white color.This has been going back and forth between available and in-store only, and so may depend on the availability at your local Walmart. If you really want this price it's worth checking the link below. Sarah Tew/CNET Cheap and dead simple, the Roku Express delivers all the joy of Roku's platform, but in a crazy-small package. It comes with a remote, micro-USB and HDMI ports, an HDMI cable, plus a tiny sticker to keep it in place. That said, with the 4K version on sale for just $5 more; that's far and away the better deal.
