Vlad Savov from The Verge reports of his experience using the first smartphone with a fingerprint scanner built into the display: After an entire year of speculation about whether Apple or Samsung might integrate the fingerprint sensor under the display of their flagship phones, it is actually China's Vivo that has gotten there first. At CES 2018, I got to grips with the first smartphone to have this futuristic tech built in, and I was left a little bewildered by the experience. The mechanics of setting up your fingerprint on the phone and then using it to unlock the device and do things like authenticate payments are the same as with a traditional fingerprint sensor. The only difference I experienced was that the Vivo handset was slower -- both to learn the contours of my fingerprint and to unlock once I put my thumb on the on-screen fingerprint prompt -- but not so much as to be problematic. Basically, every other fingerprint sensor these days is ridiculously fast and accurate, so with this being newer tech, its slight lag feels more palpable. Vivo is using a Synaptics optical sensor called Clear ID that works by peering through the gaps between the pixels in an OLED display (LCDs wouldn't work because of their need for a backlight) and scanning your uniquely patterned epidermis. The sensor is already in mass production and should be incorporated in several flagship devices later this year.

Many media outlets are reporting that the U.S. government's top-secret Zuma satellite may have run into some serious problems during or shortly after its Sunday launch. Zuma was launched atop a SpaceX Falcon 9 rocket from Florida's Cape Canaveral Air Force Station Sunday evening -- a launch that also featured a successful landing back on Earth by the booster's first stage. While everything seemed fine at the time, rumors began swirling within the spaceflight community that something had happened to Zuma. "According to one source, the payload fell back to Earth along with the spent upper stage of the Falcon 9 rocket," Ars Technica's Eric Berger wrote. Scientific American reports: To be clear: There is no official word of any bad news, just some rumblings to that effect. And the rocket apparently did its job properly, SpaceX representatives said. "We do not comment on missions of this nature, but as of right now, reviews of the data indicate Falcon 9 performed nominally," company spokesman James Gleeson told Space.com via email. Space.com also reached out to representatives of aerospace company Northrop Grumman, which built Zuma for the U.S. government. "This is a classified mission. We cannot comment on classified missions," Northrop Grumman spokesman Lon Rains said via email. All we know about the satellite itself is that it was destined for a low-Earth orbit and built for the U.S. government. We will update this story if we hear anything else about Zuma's status.

An anonymous reader quotes a report from Grub Street: Per Business Insider, Jack in the Box CEO Leonard Comma told an industry crowd that "it just makes sense" to swap cashiers for inanimate machines in the year 2018. Not because he thinks 2018 will be the year that fast food gets technologized so much as it's the year that Jack in the Box's home state of California increases the minimum wage to $11. In fact, wage bumps hit 18 states this year, with California on pace to become the first $15-wage state in coming years -- a prospect that terrifies industry executives. Jack in the Box has flirted with the idea of installing automated kiosks before. As early as 2009, it tested them out, and apparently found that they increase store efficiency and average check totals -- not bad at all if money's your bottom line. But according to Comma, the chain's executives balked because the upfront cost of converting from people to machines was still too great. What a difference a dollar an hour apparently makes: He told the crowd that with "the rising costs of labor," it's time to start thinking about automating restaurants.

"AT&T and Comcast have solidified a court victory over the metro government in Nashville, Tennessee, nullifying a rule that was meant to help Google Fiber compete against the incumbent broadband providers," reports Ars Technica. From the report: The case involved Nashville's "One Touch Make Ready" ordinance that was supposed to give Google Fiber and other new ISPs faster access to utility poles. The ordinance let a single company make all of the necessary wire adjustments on utility poles itself instead of having to wait for incumbent providers like AT&T and Comcast to send work crews to move their own wires. But AT&T and Comcast sued the metro government to eliminate the rule and won a preliminary victory in November when a U.S. District Court judge in Tennessee nullified the rule as it applies to poles owned by AT&T and other private parties.

The next step for AT&T and Comcast was overturning the rule as it applies to poles owned by the municipal Nashville Electric Service (NES), which owns around 80 percent of the Nashville poles. AT&T and Comcast achieved that on Friday with a new ruling from U.S. District Court Judge Aleta Trauger. Nashville's One Touch Make Ready ordinance "is ultra vires and void or voidable as to utility poles owned by Nashville Electric Service because adoption of the Ordinance exceeded Metro Nashville's authority and violated the Metro Charter," the ruling said. Nashville is "permanently enjoined from applying the Ordinance to utility poles owned by Nashville Electric Service." The Nashville government isn't planning to appeal the decision, a spokesperson for Nashville Mayor Megan Barry told Ars today.

In an email Tuesday, Tesla said that its manufacturing of the long-awaited electricity-producing shingles began last month at a factory in Buffalo built with backing from New York State. It comes more than a year after Tesla unveiled the shingles to a mix of fanfare and skepticism. Bloomberg reports: The appeal: a sleek, clean solar product, especially for homeowners seeking to replace aging roofs. The tiles -- from most angles -- look like ordinary shingles. They allow light to pass from above and onto a standard flat solar cell. Tesla, the biggest U.S. installer of rooftop-solar systems, piloted the product on the homes of several employees. The company expects to begin installing roofs for customers within the next few months.

Tesla started production of solar cells and panels about four months ago at its Gigafactory 2 in Buffalo. New York committed $750 million to help build the 1.2 million-square-foot factory, which currently employs about 500 people. The plant will eventually create nearly 3,000 jobs in Western New York and nearly 5,000 statewide, Governor Andrew Cuomo said in 2015.

New submitter Rick Schumann writes: The senate bill to block the FCC repeal of Obama-era internet net neutrality rules now has 40 co-sponsors, up from the 30 co-sponsors it had yesterday. The bill, being driven by Senate minority Democrats, requires only a simple majority vote in order to be passed, although Washington insiders are currently predicting the bill will fail. "The bill would use authority under the Congressional Review Act (CRA) to block the FCC's repeal from going into effect," reports The Hill. "And with more than 30 senators on board, the legislation will be able to bypass the committee approval process and Democrats will be able to force a vote on the floor."

An anonymous reader writes: The United Kingdom has recently debated banning reidentification in its new data privacy law. This proposal has quickly been identified as dangerous and criticized, as it was argued this is not only ineffective but would also put at risk legitimate security and privacy researchers. Following public outcry, the UK government amended the bill to include safe-guards allowing researchers to study anonymization weaknesses. Researchers will also gain a new channel of disclosure via the Information Commissioner Office (ICO). According to The Guardian, "Researchers will have to notify the ICO within three days of successfully deanonymizing data, and demonstrate that they had acted in the public interest and without intention to cause damage or distress in re-identifying data."

Kodak has joined the cryptocurrency craze by launching its own KodakCoin, a cryptocurrency for photographers. As soon as the news was announced, Kodak's stock (KODK) jumped more than 60 percent. The Verge reports: KodakCoins will work as tokens inside the new blockchain-powered KodakOne rights management platform. The platform will supposedly create a digital ledger of rights ownership that photographers can use to register and license new and old work. Both the platform and cryptocurrency are supposed to "empower photographers and agencies to take greater control in image rights management," according to the press release. The digital currency is meant to create a new economy for photographers to receive payment and sell work on a secure platform. But while Kodak's proposed blockchain-powered platform and virtual coin sound good on paper, it's not clear why the photography company needs to use blockchain to achieve its goals, rather than just create another social media platform instead. It appears that Kodak, like the other tea and vape companies that received media attention last month for making the abrupt leap to blockchain, could just be trying to capitalize on the current cryptocurrency mania.

An anonymous reader quotes a report from Ars Technica: An open letter to Apple from some investors sparked the tech giant to respond by promising new software tools for parents to restrict and monitor their kids' smartphone use. In a report by The Wall Street Journal, Apple states it has plans to create new software features that will make its current parental controls on iPhone and other devices "even more robust." "We think deeply about how our products are used and the impact they have on users and the people around them," Apple said in its statement to The Wall Street Journal. "We take this responsibility very seriously and we are committed to meeting and exceeding our customers' expectations, especially when it comes to protecting kids."

Apple didn't provide details on its planned, improved parental control features, but it did point back to the controls its software has had in place since 2008. The Settings app on every iPhone has a parental control section that allows adults to restrict website access, control in-app purchases, and install or delete apps, among other things. But those existing settings haven't been enough to quell the worries of the investors who wrote an open letter to Apple last week, expressing concern about the effect smartphones can have on kids who are glued to those devices.

The Freedom of the Press Foundation is reporting that James Dolan, former Marine and co-creator of the whistleblower submission system SecureDrop alongside Aaron Swartz and Wired editor Kevin Poulsen, has died at age 36. He reportedly took his own life. Gizmodo reports: First deployed as StrongBox with The New Yorker, organizations such as the Washington Post, the New York Times, the Associated Press, and Gizmodo Media Group have all come to rely on SecureDrop -- which allows highly secure communication between journalists and sources in possession of sensitive information or documents. As an industry tool, it has become invaluable for reporters. Dolan joined the Freedom of the Press Foundation to maintain SecureDrop after co-creator Aaron Swartz took his life in 2013 at age 26, as pressure mounted in a federal investigation against him that many felt was overzealous. Memorial services have not yet been announced, and presently the circumstances of Dolan's death are not known.

Paul Vigna, writing for WSJ: Prices for some of the most popular cryptocurrencies dropped sharply Monday. One apparent reason: an adjustment from a popular website on its digital-currency price quotes (Editor's note: the link may be paywalled; alternative source). A website called coinmarketcap.com on Monday removed data from some South Korean exchanges from its price quotes for a range of virtual currencies including bitcoin, Ethereum and Ripple's XRP. The move followed a South Korean government crackdown on cryptocurrencies. The move by coinmarketcap caused some amount of chaos when prices across the board suddenly plunged. In mid-Monday trading, XRP had fallen 26% over the past 24 hours, Bitcoin Cash was down 18%, and litecoin was down 12%. Of the top 40 cryptocurrencies, 31 were down, including bitcoin and Ethereum. [...]

Coinmarketcap has become one of the most popular destinations for price quotes as the sector surged last year. According to Amazon's web-ranking service, coinmarketcap is currently the 154th most popular website in the world, in the same ballpark as Chinese retail giant Alibaba.com. The website's rejiggered prices led to a flip in market-value rankings on the site. Ethereum, with a $109 billion total market valuation, moved into second place, the spot previously occupied by XRP, which fell to third place with a $97 billion market value. Bitcoin remained number one, with a $255 billion market value.

From a report on VentureBeat: Smartphones and computers were designed in different eras, and they don't really work well together, forcing us to split our time between them. But Dell is trying to change that with Dell Mobile Connect software, which makes the two devices more interoperable. [...] You can now make and receive phone calls directly from your computer, and you can also send and receive text messages on your PC screen. This allows you to stay connected on your PC without worrying that you're missing phone notifications or calls. And you can use any Android app on your PC. That allows you to bring your small-screen apps like games to a bigger screen. If your computer doesn't have a touchscreen, you can control the mirrored phone game with a keyboard and mouse. [...] Dell will preload the software on new Dell consumer and business PCs, and it has a free smartphone app that works on either Android or iOS. Dell Mobile Connect will be available on all new Dell Inspiron, XPS, Vostro, or Alienware purchased worldwide in January 2018 or later.

A group of prominent developers published an open-letter on Tuesday, outlining their deep concerns about Accelerated Mobile Pages, a project by Google that aims to improve user experience of the Web. Google services already dominate the Web, and the scale at which AMP is growing, it could further reinforce Google's dominance of the Web, developers wrote. The letter acknowledges that web pages could be slow at times, but the solutions out there to address them -- AMP, Facebook's Instant Articles, Apple News -- are creating problems of their own, developers say. From the letter: Search engines are in a powerful position to wield influence to solve this problem. However, Google has chosen to create a premium position at the top of their search results (for articles) and a "lightning" icon (for all types of content), which are only accessible to publishers that use a Google-controlled technology, served by Google from their infrastructure, on a Google URL, and placed within a Google controlled user experience. The AMP format is not in itself, a problem, but two aspects of its implementation reinforce the position of Google as a de facto standard platform for content, as Google seeks to drive uptake of AMP with content creators: Content that "opts in" to AMP and the associated hosting within Google's domain is granted preferential search promotion, including (for news articles) a position above all other results. When a user navigates from Google to a piece of content Google has recommended, they are, unwittingly, remaining within Google's ecosystem.

If Google's objective with AMP is indeed to improve user experience on the Web, then we suggest some simple changes that would do that while still allowing the Web to remain dynamic, competitive and consumer-oriented: Instead of granting premium placement in search results only to AMP, provide the same perks to all pages that meet an objective, neutral performance criterion such as Speed Index. Publishers can then use any technical solution of their choice. Do not display third-party content within a Google page unless it is clear to the user that they are looking at a Google product. It is perfectly acceptable for Google to launch a "news reader," but it is not acceptable to display a page that carries only third party branding on what is actually a Google URL, nor to require that third party to use Google's hosting in order to appear in search results. We don't want to stop Google's development of AMP, and these changes do not require that.

Feathers on birds of paradise contain light-trapping nanotechnology that makes some of the deepest blacks in the world, a new study has found. From a report: Blackbirds, it turns out, aren't actually all that black. Their feathers absorb most of the visible light that hits them, but still reflect between 3 and 5 percent of it. For really black plumage, you need to travel to Papua New Guinea and track down the birds of paradise. Although these birds are best known for their gaudy, kaleidoscopic colors, some species also have profoundly black feathers. The feathers ruthlessly swallow light and, with it, all hints of edge or contour. By analyzing museum specimens, Dakota McCoy, from Harvard University, has discovered exactly how the birds achieving such deep blacks. It's all in their feathers' microscopic structure.

A typical bird feather has a central shaft called a rachis. Thin branches, or barbs, sprout from the rachis, and even thinner branches -- barbules -- sprout from the barbs. The whole arrangement is flat, with the rachis, barbs, and barbules all lying on the same plane. The super-black feathers of birds of paradise, meanwhile, look very different. Their barbules, instead of lying flat, curve upward. And instead of being smooth cylinders, they are studded in minuscule spikes. These unique structures excel at capturing light. When light hits a normal feather, it finds a series of horizontal surfaces, and can easily bounce off. But when light hits a super-black feather, it finds a tangled mess of mostly vertical surfaces. Instead of being reflected away, it bounces repeatedly between the barbules and their spikes. With each bounce, a little more of it gets absorbed. Light loses itself within the feathers. McCoy and her colleagues, including Teresa Feo from the National Museum of Natural History, showed that this light-trapping nanotechnology can absorb up to 99.95 percent of incoming light.
