Hydrogen and Hybrids: Toyota CEO Defends Combustion Engines, Saying 'The Enemy Is Carbon' (bloombergquint.com) 265

This weekend Toyota's president drove a specially-equipped Corolla powered by an in-house hydrogen engine, reports Bloomberg. "Along with Mazda Motor Corp., Toyota showcased vehicles running on carbon-neutral propellants in a three-hour road race this weekend in Okayama." Toyota's hydrogen-powered car underscores the automaker's belief that a wide variety of vehicle types — including hybrids and hydrogen-powered cars, in addition to electric vehicles — will play a role in decarbonizing its fleet over the coming decades. That puts the company in contrast to others, such as General Motors Co., Jaguar Land Rover and Volvo Car AB, which say they'll sell only EVs two decades from now. "The enemy is carbon, not internal combustion engines," Toyoda said at a briefing Saturday. "We need diverse solutions, that's the path toward challenging carbon neutrality."

Toyota says that that different emissions-reducing car technologies are needed for different regions of the world. EVs are a good option for places like Europe, where batteries can be charged with electricity derived largely from renewable sources, the automaker says. Other options, such as hydrogen or hybrids, may be a better fit in other regions.

The technology is separate from the company's other big bet on hydrogen — hydrogen fuel cells such as those that power the Mirai passenger car. While fuel cells use the chemical reaction between hydrogen and oxygen to generate electricity, which in turn runs a motor, the hydrogen engine burns the element just like gasoline. Traditional engines only need to be tweaked in minor ways, such as changing out the fuel supply and injection systems, to make them capable of running on hydrogen, Toyota Chief Engineer Naoyuki Sakamoto said in a briefing last month. That also makes the technology a way to save some of the hundreds of thousands of jobs making parts related to combustion engines that are predicted to disappear in Japan if the automotive sector makes a full shift to EVs, according to Toyoda.

Have Scientists Disproven Google's Quantum Supremacy Claim? (scmp.com) 35

Slashdot reader AltMachine writes: In October 2019, Google said its Sycamore processor was the first to achieve quantum supremacy by completing a task in three minutes and 20 seconds that would have taken the best classical supercomputer, IBM's Summit, 10,000 years. That claim — particularly how Google scientists arrived at the "10,000 years" conclusion — has been questioned by some researchers, but the counterclaim itself was not definitive.

Now though, in a paper to be submitted to a scientific journal for peer review, scientists at the Institute of Theoretical Physics under the Chinese Academy of Sciences said their algorithm on classical computers completed the simulation for the Sycamore quantum circuits [possibly paywalled; alternative source of the same article] "in about 15 hours using 512 graphics processing units (GPUs)" at a higher fidelity than Sycamore's. Further, the team said "if our simulation of the quantum supremacy circuits can be implemented in an upcoming exaflop supercomputer with high efficiency, in principle, the overall simulation time can be reduced to a few dozens of seconds, which is faster than Google's hardware experiments".

As China unveiled a photonic quantum computer which solved a Gaussian boson sampling problem in 200 seconds that would have taken 600 million years on classical computer, in December 2020, disproving Sycamore's claim would place China being the first country to achieve quantum supremacy.

Can We Use Big Batteries to Power Our Trains? (arstechnica.com) 238

Research studying the possibility of electrifying rail-based freight "finds that the technology is pretty much ready," reports Ars Technica, "and under the right circumstances, the economics are on the verge of working out."

It helps that the price of batteries have dropped 87% over the last decade: In the U.S., the typical freight car travels an average of 241 kilometers per day when in operation. So the researchers created a battery big enough to move that distance as part of a large freight train (four locomotives, 100 freight cars, and about 7,000 tonnes of payload). They found that lithium ferrous phosphate would let each of the four locomotives be serviced by a single freight car configured as a giant battery. The battery would only occupy 40 percent of the volume of a typical boxcar and would be seven tonnes below the weight limit imposed by existing bridges. Because of the efficiency of direct electric power, the train would use only half the energy consumed by an internal combustion engine driving an on-board generator...

Using an economic measure called the "net present value," the researchers determine that switching to batteries alone would cost $15 billion. But taking the pollution damages into account turns the number into a $44 billion savings. Considering climate damages as well boosts the savings to $94 billion. Even if these damages are ignored, a rise in the price of diesel and allowing freight companies to buy power at wholesale rates come close to shifting the costs to neutral... [F]reight companies could use their capacity to provide grid stabilization services or sell back power when the price gets high. In extreme cases, this system could actually pay for the entire infrastructure.

"Preliminary estimates of the most expensive 90 hours per year in the ERCOT [Texas] market, for example, show that batteries could be discharged at $200/kWh, potentially generating enough revenue to pay for the upfront battery cost in a single year," the study says.

Special thanks to clovis (Slashdot reader #4,684) for the submission — and for also sharing "some general info about diesel-electric locomotives" and "some detail on the AC-DC-AC drive."

The US Department of Homeland Security Urges 'Digital Literacy' (cnn.com) 56

In the war against misinformation and social media-inspired violence, ultimately the social media platforms are just one front. But what about the people consuming misinformation? In June America's National Security Council unveiled a "National Strategy for Countering Domestic Terrorism," which argued that "pursuing the goal of preventing, disrupting, and deterring acts of domestic terrorism... can mean, broader still, cultivating the type of digital literacy that can empower the American public to resist those who would use online communications platforms and other venues to recruit, radicalize, and mobilize to violence."

This week America's Department of Homeland Security warned the country still faces "a diverse and challenging threat environment" including the possibility of violence "by individuals and small groups...including domestic violent extremists and those inspired or motivated by foreign terrorists and other malign foreign influences.....These actors continue to exploit online forums to influence and spread violent extremist narratives and promote violent activity." (Though they add that the agency "is not aware of an imminent and credible threat to a specific location...")

But besides offering links to mental health resources and info on law enforcement tip lines, the agency also suggests Americans "Maintain digital media literacy to recognize and build resilience to false and harmful narratives" — linking to an online publication about "Media Literacy and Critical Thinking Online."

Here's our look at the documents they're making available — and the language that they're using to convey the threat.

How Should Facebook Be Fixed? (vox.com) 171

The technology site Recode interviewed 12 "leading thinkers and leaders on Facebook today," including the Senator pushing tech-industry updates for U.S. antitrust law, an early researcher on viral misinformation, and a now-critical former Facebook executive. "[M]ost believe that Facebook can be fixed, or at least that some of its issues are possible to improve..." Their ideas are wide-ranging, with some more ambitious and unexpected than others. But common themes emerge in many of their answers that reveal a growing consensus about what Facebook needs to change and a few different paths that regulators and the company itself could take to make it happen:

- Antitrust enforcement. Facebook isn't just Facebook but, under the Meta umbrella, also Instagram, WhatsApp, Messenger, and Oculus. And several experts Recode interviewed believe that forcing Facebook to spin off these businesses would defang it of its concentrated power, allow smaller competitors to arise, and challenge the company to do better by offering customers alternatives for information and communication.

- Create a federal agency to oversee social media, like the Food and Drug Administration. The social media industry has no dedicated oversight agency in the U.S. the way that other industries do, despite its growing power and influence in society. That's why some people we interviewed advocated for making a new agency — or at least increasing funding for the existing FTC — so that it could regulate safety standards on the internet the same way the FDA does for food and pharmaceutical drugs.

- Change Facebook's leadership. Facebook's problems are almost synonymous with the leadership of Mark Zuckerberg, who has unilaterally controlled the company he started in his Harvard dorm room in 2004. Many interviewees believe that for any meaningful change to happen, Facebook needs an executive shake-up, starting from the very top... some experts Recode interviewed suggested that Facebook executives should be criminally prosecuted for either misleading business partners or downplaying human harms their company causes.

The experts also want reforms on the safety-from-prosecution shields of Section 230 "in a way that won't run into First Amendment challenges," and also increased transparency from social media companies about problematic content.

"Some of the experts interviewed by Recode argued that Facebook and other social media companies should be legally required to share certain internal data with vetted researchers about what information is circulating on their platforms."

Penpot, the Vector Design Web-app Taking On Figma and Canva With FOSS, Hits Beta (penpot.app) 55

"It's Open Source. It's free," says a web page at Penpot.app.

Slashdot reader kxra writes: Penpot is a free-software, web-based vector design platform using .svg as a first-class filetype used as the underlying storage for all designs.

As more design teams around the world move to the convenience of multi-device synchronized and collaborative web apps, this is a welcome respite from proprietary vendor lock-in by the likes of Figma and Canva. Penpot has finally launched as Beta, with competitive features such as a template library that all creators can pull from.

It's created by Kaleidos Open Source, the same team behind the project management tool Taiga for Agile teams which is taking on the likes of JIRA and Confluence with FLOSS.

"Not having a free & open source UX/UI tool that would make devs participate in the design process and bridge the gap between UX/UI and code was a terrible itch for us..." explains the FAQ at Penpot.app. But it also answers the question: why Open Source? Software Technology has the unique advantage, compared to other industries and intellectual property, of having almost zero cost to replicate itself, thus providing a wonderful chance to massively distribute the tools for a more digitally sovereign society. Besides the pure license aspect of it and its legal framework, Open Source fosters more engaging communities where the lines between user and contributor are often blurred...

Penpot requires a browser, that's it. If you want to host your own Penpot instance, that's fine too. We plan to release a native app bundle later this year.

There is a theme here. Universal access. That's why we love to call our product Penpot, there's nothing more personal and yet more universal than a pot full of pens. It's all about choice.

Its GitHub repository already has 5,200 stars and 41 contributors.

US Rollout of 5G Frequencies Delayed Over Aviation Safety Concerns. Are They Warranted? (usatoday.com) 31

Because of a "surprising and sudden request" from America's Federal Aviation Administration that's "based on unverified potential radio interference, a highly anticipated increase in 5G speeds and availability just got put on hold," writes the president/chief analyst of market research/consulting firm TECHnalysis.

But in an opinion piece for USA Today, he asks if the concern is actually warranted? [A]s soon as you start to dig into the details, the concerns quickly seem less practical and more political. Most notably, the plan to launch 5G services on C-Band frequencies has been in the works for several years and really took on momentum after the three big U.S. carriers spent over $80 billion earlier this year to get access to these frequencies. In addition, a report that the FAA cited as part of their complaint has been out for well over a year, so why the last-minute concerns?

U.S. government agencies are, unfortunately, known to hold grudges against one another, sometimes without real clarity as to what's actually involved, as appears to be the case here... Some 40 countries around the world are already using most of the C-Band frequencies for 5G (part of the reason the U.S. has fallen behind on the 5G front), and none have reported any interference with radio altimeters on planes in their countries, the wireless trade association CTIA argues on its website 5GandAviation.com. In addition, new filtering technologies being built into a somewhat obscure part of smartphones called the RF (radio frequency) front end, such as Qualcomm's recently introduced ultraBAW filters, can reduce interference issues on next generation smartphones.

All told, there are numerous reasons why the FAA's concerns around 5G deployment look to be more of a red herring than a legitimate technical concern. While it is true that some older radio altimeters with poor filtering might have to be updated and/or replaced to completely prevent interference, it's not clear that the theoretical interference would even cause an issue.

The article complains that the delayed expansion of bandwidth "could also delay important (and significant) economic impacts," since every previous change in cellular service levels "has triggered billions of dollars of new business and thousands of new jobs by creating new opportunities that faster wireless networks bring with them and 5G is expected do the same...

"While airplane safety shouldn't be compromised in any way, an overabundance of unnecessary caution on this issue could have a much bigger negative impact on the U.S.'s technology advancements and economy than many realize."

Will Microsoft Beat Facebook to the Metaverse? (venturebeat.com) 45

"When comparing Meta — formerly Facebook — and Microsoft's approaches to the metaverse, it's clear Microsoft has a much more grounded and realistic vision," argues an analyst at data analytics/consultancy company GlobalData: Meta is set to grab a large portion of the $51 billion revenues from VR that GlobalData expects will be generated by 2030. Facebook led the consumer VR headsets market in 2020 and registered 255 VR-related patents between 2016 and 2020. And, as Meta, the company also plans to launch an enterprise-grade headset in Q4 2021. However, VR hardware and software have not been widely adopted. This is attributable to several issues, including latency, nausea, high prices, privacy concerns, and a lack of compelling content. While technologies such as 5G, cloud services, and motion tracking should help to address latency and nausea issues, improving content and developing effective data privacy practices will be paramount for VR's success (more on data privacy in a moment). For these reasons VR is not yet ready to take on the task of the metaverse.

Microsoft seems to have understood better than Meta how people actually use technology. All you need to use Mesh — Microsoft's so-called gateway to the metaverse — is your current smartphone or laptop. No clunky headsets or expensive tech setups are needed. With this approach, Microsoft is keeping its focus on available capabilities and enterprise applications over Meta's vision of total lifestyle adoption. Microsoft Teams also currently has over 145 million daily active users, whereas the total cumulative installed base of VR headsets is less than 17 million. From these numbers alone, Mesh for Microsoft Teams has a possible user base of more than eight times the number of users Meta could hope to reach with its VR headsets.

Facebook's promises of protecting data's privacy in the metaverse "will not be enough to reassure most future users," the article argues.

"Microsoft, on the other hand, is a market leader in data privacy and, when ranked by the 10 themes that matter most to the social media industry, is in second place overall, according to GlobalData's Social Media Thematic Scorecard. Meta is ranked 21st overall out of 35 companies on the scorecard, and its activity with regards to data privacy will be highly detrimental to its future performance."

Besides new issues like hyper-personalized ads, the metaverse will still face the old problem of content moderation, the article suggests — only now spread across a massive scale. And the article ultimately argues that "The metaverse will suffer from the same issues that plague the current version of the internet unless the right actions are taken by those that end up with control..."

Microsoft's better position as a future leader in the metaverse "comes with responsibilities, and Microsoft needs to be prepared to face them...."

Internet of Things Projected To Generate Up To $12.6 Trillion By 2030 (axios.com) 31

From smart home devices to sensor-laden factories, the Internet of Things (IoT) is poised to generate trillions of dollars in value by the end of the decade, according to a new report from the McKinsey Global Institute (MGI). Axios reports: MGI estimates by 2030 the IoT could enable between $5.5 trillion and $12.6 trillion in value globally. About 65% of that value is projected to be created in business applications, like smart factories or offices, rather than consumer applications like internet-connected robot vacuums. The IoT economy is predicted to lean toward developing countries -- which benefit from being able to build smart facilities from the ground up rather than retrofitting -- and China in particular, which MGI expects will generate more than a quarter of all IoT value by 2030.

It's far from certain all of this economic value will be realized. [...] Whether the many companies contributing to the sector agree on interoperability standards that would make the physical IoT more like the digital, highly interoperable internet. Up to three-quarters of the high-end estimates for future IoT value depend on establishing interoperability, Chui notes, while cybersecurity concerns will remain a lingering headwind.

Slashdot Asks: Should YouTube Remove the Dislike Count? (vortex.com) 141

On Wednesday, YouTube announced a controversial decision to make the "dislike" count on videos private across its platform. While the intent is to better protect its creators from harassment and reduce the threat of "dislike attacks," the decision has been met with a lot of criticism, especially among prominent tech YouTubers like MKBHD who claims the dislike count is a "useful tool to see how helpful a video will be at a glance." Surely, you've searched for a "how-to" video and immediately clicked off because you noticed the like-to-dislike ratio completely skewed. In my experience, it's been a very good indicator as to how accurate or helpful a video is.

Long-time Slashdot reader Lauren Weinstein weighs in on the decision, saying a more "nuanced approach would be preferable." They write: In particular, my view is that it is reasonable to remove the publicly viewable Dislike counts from videos by default, but that creators should be provided with an option to re-enable those counts on their specific videos (or on all of their videos) if they wish to do so. With YouTube removing the counts by default, YouTube creators who are not aware of these issues will be automatically protected. But creators who feel that showing Dislike counts is good for them could opt to display them. Win-win! What are your thoughts on YouTube's decision to remove the dislike count? Did they go too far or does their reasoning make sense?

Coinbase Goes Social by Letting Users Tout Crypto Allocations (bloomberg.com) 16

Coinbase Global is adding a slew of social-networking capabilities, one of which will make it easier for traders to share information about their allocations on platforms such as Instagram and Twitter. From a report: The biggest U.S. cryptocurrency exchange said Friday it's adding a Share button that will let traders detail what coins they own on social networks. More ways of sharing data about trades are in the works as well, the company said in a blog. The effort is likely aimed at harnessing word of mouth about crypto investing to attract more users. Coinbase said this week that its monthly transacting users had decreased sequentially in the third quarter. At the same time, the firm boosted its recurring-user forecast for the full year.

Contract Lawyers Face a Growing Invasion of Surveillance Programs that Monitor their Work (washingtonpost.com) 59

The attorneys worry that if law firms, traditionally the defenders of workers' rights, are turning to the programs, why wouldn't every other business? From a report: Camille Anidi, an attorney on Long Island, quickly understood the flaws of the facial recognition software her employers demanded she use when working from home. The system often failed to recognize her face or mistook the Bantu knots in her hair as unauthorized recording devices, forcing her to log back in sometimes more than 25 times a day. When she complained, she said, her bosses brushed it off as a minor technical issue, though some of her lighter-skinned colleagues told her they didn't have the same problem -- a common failing for some facial recognition systems, which have been shown to perform worse for people of color. So after each logout, Anidi gritted her teeth and did what she had to do: Re-scan her face from three angles so she could get back to a job where she was often expected to review 70 documents an hour.

"I want to be able to do the work and would love the money, but it's just that strain: I can't look left for too long, I can't look down, my dog can't walk by, or I get logged out," she said. "Then the company is looking at me like I'm the one delaying!" Facial recognition systems have become an increasingly common element of the rapid rise in work-from-home surveillance during the coronavirus pandemic. Employers argue that they offer a simple and secure way to monitor a scattered workforce. But for Anidi and other lawyers, they serve as a dehumanizing reminder that every second of their workday is rigorously probed and analyzed: After verifying their identity, the software judges their level of attention or distraction and kicks them out of their work networks if the system thinks they're not focused enough.

Contract attorneys such as Anidi have become some of America's first test subjects for this enhanced monitoring, and many are reporting frustrating results, saying the glitchy systems make them feel like a disposable cog with little workday privacy. But the software has also become a flash point for broader questions about how companies treat their remote workforces, especially those, like contract attorneys, whose short-term gigs limit their ability to push for change. The attorneys also worry that it could become the new norm as more jobs are automated and analyzed: If the same kinds of law firms that have litigated worker protections and labor standards are doing it, why wouldn't everyone else?

Microsoft To Block Windows 11 Browser Workarounds (thurrott.com) 134

The creator of EdgeDeflector said this week that the latest Insider build of Windows 11 now blocks all default browser workarounds. If this functionality makes its way to the finished product, it will mark a new, dark chapter for Microsoft, which told the media at the Windows 11 launch that it was aware that it had made changing app defaults pointlessly difficult, but that it had not done so maliciously and would fix it. This is the opposite of that claim. From a report: "Something changed between Windows 11 builds 22483 and 22494 (both Windows Insider Preview builds)," EdgeDeflector creator Daniel Aleksandersen writes in a new blog entry. "The build changelog ... omitted the headline news: you can no longer bypass Microsoft Edge using apps like EdgeDeflector."

Microsoft not communicating effectively? I find that hard to believe. Cough. But Microsoft moving to make Windows 11 behave even more maliciously towards its users and browser rivals? That I have a hard time with. Basically, EdgeDeflector, as well as third-party browsers like Mozilla Firefox and Brave, intercept OS-level URL requests that force you to use Microsoft Edge even when you have gone through the incredibly ponderous steps to make a non-Edge browser the default in Windows 11. But in the latest Insider Preview build, Microsoft is changing how these URL requests work. And it's no longer possible to intercept URL requests that force users to use Edge instead of their default browser. (In the Insider builds. This functionality will come to mainstream users in the coming months unless we can change Microsoft's collective mind.)

Biden Signs Bill To Secure Telecoms Against National Security Threats (axios.com) 27

President Biden signed into law a bill that requires the Federal Communications Commission (FCC) to secure telecommunications systems against potential foreign threats to national security. From a report: In recent years, lawmakers have increasingly voiced concerns about Chinese telecom giants' operations in the U.S., and possible surveillance by the Chinese government. Under the new law, the FCC is barred from considering authorization for products made by companies on its "covered list," which includes Huawei and ZTE. The designation blocks U.S. companies from using FCC funds to purchase communications equipment and services that the U.S. government considers a national security threat. The bill received near-unanimous support in Congress. It was sponsored by Sens. Marco Rubio (R-Fla.) and Ed Markey (D-Mass.), along with House Minority Whip Steve Scalise (R-La.) and Rep. Anna Eshoo (D-Calif.).

Windows 11 SE Won't Be Sold Separately, Can't Be Reinstalled Once Removed (arstechnica.com) 87

An anonymous reader quotes a report from Ars Technica: Microsoft is taking the fight to Chromebooks in schools with the $250 Surface Laptop SE, but inexpensive hardware is only part of the equation. One reason Chromebooks have succeeded in education is because of Chrome OS, which is well-suited for lower-end hardware, easy for IT administrators to manage, and hard to break with errant apps or malware. Microsoft's answer to Chrome OS is Windows 11 SE. Unlike past efforts like Windows in S mode (which is still its own separate thing), Windows 11 SE isn't just a regular version of Windows with a cheaper license or a cut-down version that runs fewer apps. Windows 11 SE defaults to saving all files (including user profile information) to students' OneDrive accounts, and it has had some standard Windows 11 features removed to ensure a "distraction-free" learning environment that performs better on low-end devices. The operating system also gives IT administrators exclusive control over the apps and browser extensions that can be installed and run via Microsoft Intune.

If you're a school IT administrator with a fleet of PC laptops or desktops, you might wonder if you can buy and install Windows 11 SE on hardware you already have so you can benefit from its changes without buying new hardware. The answer, Microsoft tells us, is no. The only way to get Windows 11 SE is on laptops that ship with Windows 11 SE. And if you re-image a Windows 11 SE device with a different version of Windows 10 or Windows 11, it won't even be possible to reinstall Windows 11 SE after that. [...] Microsoft has published documentation (PDF) that more fully explains the differences between Windows 11 SE and the other editions of Windows (including Windows in S mode).

Google Caught Hackers Using a Mac Zero-Day Against Hong Kong Users (vice.com) 13

Google researchers caught hackers targeting users in Hong Kong exploiting what were at the time unknown vulnerabilities in Apple's Mac operating system. According to the researchers, the attacks have the hallmarks of government-backed hackers. From a report: On Thursday, Google's Threat Analysis Group (TAG), the company's elite team of hacker hunters, published a report detailing the hacking campaign. The researchers didn't go as far as pointing the finger at a specific hacking group or country, but they said it was "a well resourced group, likely state backed."

"We do not have enough technical evidence to provide attribution and we do not speculate about attribution," the head of TAG Shane Huntley told Motherboard in an email. "However, the nature of the activity and targeting is consistent with a government backed actor." Erye Hernandez, the Google researcher who found the hacking campaign and authored the report, wrote that TAG discovered the campaign in late August of this year. The hackers had set up a watering hole attack, meaning they hid malware within the legitimate websites of "a media outlet and a prominent pro-democracy labor and political group" in Hong Kong. Users who visited those websites would get hacked with an unknown vulnerability -- in other words, a zero-day -- and another exploit that took advantage of a previously patched vulnerability for MacOS that was used to install a backdoor on their computers, according to Hernandez.

Lawsuit Over Subway Tuna Now Says Chicken, Pork, Cattle DNA Were Detected 136

A new version of a lawsuit accusing Subway of deceiving the public about its tuna products said lab testing shows they contain animal proteins such as chicken, pork and cattle, and not the advertised "100% tuna." From a report: Karen Dhanowa and Nilima Amin filed a third version of their proposed class action this week in the federal court in San Francisco, near their homes in Alameda County. Subway said in a statement it will seek to dismiss the "reckless and improper" lawsuit. The chain said the plaintiffs have "filed three meritless complaints, changing their story each time," and that its "high-quality, wild-caught, 100% tuna" was regulated strictly in the United States and around the world. Since the case began in January, Subway has run TV ads and launched a website defending its tuna. It also revamped its menu but not its tuna, saying an upgrade wasn't needed. The original complaint claimed that Subway tuna salads, sandwiches and wraps were "bereft" of tuna, while an amended complaint said they were not 100% sustainably caught skipjack and yellowfin tuna.

South Korea Tests System for Controlling Air Taxis (reuters.com) 27

South Korea demonstrated a system for controlling urban air mobility vehicles (UAM) on Thursday, which it hopes will serve as taxis between major airports and downtown Seoul as soon as 2025, cutting travel time by two-thirds. From a report: Last year, South Korea announced a roadmap to begin commercial urban air travel by 2025. The transport ministry estimates such services could cut travel time for distances between 30-50km (19-31 miles) from an hour by car to 20 minutes by air. "As UAM is expected to become one of the common means of transportation that citizens use in daily life, it is absolutely imperative that we test and try out UAM services in various environments," Transport Minister Noh Hyeong-ouk, who attended the demonstration on Thursday, said in a statement. A pilot flew a two-seat model made by Germany's Volocopter at Seoul's Gimpo Airport to test and demonstrate its control and coordination.

Whole Genome Sequencing Could Save NHS Millions of Pounds, Study Suggests (theguardian.com) 26

The use of whole genome sequencing could save the NHS millions of pounds, a study suggests, after it found a quarter of people with rare illnesses received a diagnosis for their condition through the technology. From a report: In some cases, the findings have provided reassurance for families that they have not passed their condition on to their children, while in others they have inspired life-changing treatments. Though individually uncommon, rare inherited diseases affect about 6% of the UK population, or roughly 3 million people. Traditionally, geneticists searched for the abnormalities underpinning such conditions by looking at the person's chromosomes through a microscope, but this is no good at spotting tiny, but often highly significant changes, such as single letter substitutions in the genetic code. Because of this, "many of the people who have a rare disease either live very long diagnostic odysseys to get an answer for why they are like they are, or they do not get an answer in their entire lifetime," said Prof Sir Mark Caulfield at Queen Mary University of London (QMUL), a former chief scientist at Genomics England. In 2013, the UK government launched the 100,000 Genomes Project to investigate whether WGS -- which involves reading through the entire 3bn pairs of letters in the human genome -- could help doctors better understand the cause of patients' symptoms, and identify other family members who may be at risk. Five years later, NHS England became the first national health care system in the world to offer WGS to people with undiagnosed rare diseases and cancer as part of routine care.

Google Wants To Save the Planet With Satellite Images (bloomberg.com) 9

Google Earth Engine has created a vast trove of open source satellite imagery and augmented it with data-analysis software that makes it relatively easy for skilled outsiders to draw up their own interactive maps. From a report: More important, its team of staff scientists (Google won't say how many) wrangles massive data sets to answer critical questions for a constellation of pro bono "clients" that includes conservation groups, city agencies, community advocates, and researchers. The 20,000 image files added to the Earth Engine team's collection each day are more than just static photos. Satellites gather, for example, detailed information on the soil composition more than a foot underground and the amount of water vapor rising from farmland. Staffers help clients distill relevant information and relay it to the field. Via radio, the nomads in Senegal learn where to find a drink for their cows; bright pink dots on interactive maps inform the indigenous Peruvians of the locations of logging activity; and a shared website targets the spots in LA where trees will likely do the most good.

"The raw data is not enough. Government officials now tell us, "We're drowning in data, but we're thirsty for insights,'" says Rebecca Moore, who runs the team. "We invented Google Earth Engine to allow scientists to easily analyze data and ask questions about how the climate is changing and answer in seconds or minutes instead of years." Other companies, including Amazon.com and Microsoft, have technical services with capabilities comparable to Earth Engine, but experts in the field say the sheer number of work-hours Moore's staff dedicates to volunteer efforts sets it apart. "It's just a remarkable level of transparency and information that wasn't available before," says Mikaela Weisse, project manager for Global Forest Watch, an open source online tool that monitors deforestation. Joe Morrison, a vice president at satellite imaging company Umbra, who writes a newsletter about the industry, calls Earth Engine the most important contribution to climate science in 50 years.
