A team of scientists from the Singapore University of Technology and Design discovered that, using simple chemistry, the organic polymer chitin -- contained in the exoskeletons of insects and crustaceans -- can easily be transformed into a viable building material for basic tools and habitats. The findings have been published in the journal PLOS ONE. Ars Technica reports: "The technology was originally developed to create circular ecosystems in urban environments," said co-author Javier Fernandez. "But due to its efficiency, it is also the most efficient and scalable method to produce materials in a closed artificial ecosystem in the extremely scarce environment of a lifeless planet or satellite." [T]he authors of the current paper point out that most terrestrial manufacturing strategies that could fit the bill typically require specialized equipment and a hefty amount of energy. However, "Nature presents successful strategies of life adapting to harsh environments," the authors wrote. "In biological organisms, rigid structures are formed by integrating inorganic filler proceed from the environment at a low energy cost (e.g., calcium carbonate) and incorporated into an organic matrix (e.g., chitin) produced at a relatively high metabolic cost."

Fernandez and his colleagues maintain that chitin is likely to be part of any planned artificial ecosystem because it is so plentiful in nature. It's the primary component of fish scales and fungal cell walls, for example, as well as the exoskeletons of crustaceans and insects. In fact, insects have already been targeted as a key source of protein for a possible Martian base. And since the chitin component of insects has limited nutritional value for humans, extracting it to make building materials "does not hamper or compete with the food supply," the authors wrote. "Rather, it is a byproduct of it."

With space junk piling up around our planet, the International Space Station needed to perform a last-minute avoidance maneuver Tuesday to steer clear of an "unknown piece of space debris expected to pass within several kilometers." From a report: Mission Control in Houston conducted the move at 2:19 p.m. PT using the Russian Progress resupply spacecraft docked to the ISS to help nudge the station out of harm's way. "Out of an abundance of caution, the Expedition 63 crew will relocate to their Soyuz spacecraft until the debris has passed by the station," NASA said in a statement prior to the move. The maneuver went off smoothly, NASA administrator Jim Bridenstine reported. "The astronauts are coming out of safe haven," he tweeted after the ISS relocated.

sciencehabit writes: A mini-arms race is unfolding in the supposed field of quantum radar, spurred by press reports in 2016 that China had built one -- potentially threatening the ability of stealthy military aircraft to hide from conventional radars. Governments around the world have tasked physicists to look into the idea. Whereas a conventional radar searches for objects by detecting pulse of microwaves reflected from them, quantum radar would utilize pulses of microwaves linked by a quantum connection called entanglement. The system would retain one pulse and measure it in concert with the one reflected from the object. Correlations between the two would make it easier to spot an object through the glare of the surroundings. Or so researchers hoped. Groups have demonstrated elements of a quantum radar, but only in limited experiments that a nonquantum system can still match. And fundamental physical limits suggest the scheme can't beat ordinary radar for long-range detection. Even one of the inventors of the basic concept thinks it won't work when applied to radar.

Mike Morhaime, the cofounder of Blizzard Entertainment, has launched a new game company called Dreamhaven, and it has established two new game studios: Moonshot and Secret Door. VentureBeat reports: The Irvine, California-based company is a pretty good clue that Morhaime and his wife Amy Morhaime weren't quite done with games when they left Activision Blizzard in 2018. Mike will be the CEO of Dreamhaven, while Amy will head operations. They have hired a number of (mostly former Blizzard) industry veterans to help run their studios, which will work on separate games. That's an ambitious startup, as working on two games at once is a handful. But it's not without precedent, as Harold Ryan's Probably Monsters startup in Seattle also has two studios working on two games at once. What makes the Morhaimes' company unique so far is that they're funding it themselves. [...] So far, the company has 27 employees across all three entities, and it's hiring more staff. The artwork on the company's homepage combines aspects of both fantasy and science fiction, but the company isn't yet saying what games it is working on, nor is it talking about genres. But it is working on a familiar model, as it closely resembles the way Morhaime ran things at Blizzard, with an emphasis on quality, iteration, and giving creative staff enough time. The parent company's role is to provide guidance and funding, as well as central services that each studio will need, such as communications and human resources. But each studio will make its own decisions about how to make the best games, Morhaime said. The founders have equity in the parent company.

Moonshot's leaders are Jason Chayes, Dustin Browder, and Ben Thompson. Chayes was previously an executive producer at Blizzard Entertainment, where he worked on the Hearthstone team. He also worked at Electronic Arts and Disney. Browder's 25-year career includes roles as the game director for StarCraft II, Heroes of the Storm, Command & Conquer, and The Lord of the Rings. Thompson's credits include creative director for Hearthstone and art director for the World of Warcraft trading card game, with additional credits on Dungeons & Dragons and Magic: The Gathering. Moonshot is also home to a team of seasoned developers who've worked on some of gaming's most popular franchises.

Dreamhaven's second game studio, Secret Door, has a leadership team of Chris Sigaty, Alan Dabiri, and Eric Dodds. Sigaty's roles have included executive producer on Hearthstone, StarCraft II, and Heroes of the Storm, as well as lead producer on the original Warcraft III. Dodds was the original game director of Hearthstone and veteran game designer on World of Warcraft and StarCraft. Dabiri has filled both technical director and game director roles and has worked on Warcraft III, StarCraft II, and Heroes of the Storm. Sigaty was at Blizzard for almost 24 years, working closely with Chayes on games like StarCraft II: Wings of Liberty. He left Blizzard at the end of 2019 and to devote some time to family. He also talked with Morhaime and Chayes.

Legendary horror game Amnesia: The Dark Descent and A Machine for Pigs is now open source, meaning that modders can dig in and see what lies underneath the hood of both games. Polygon reports: The full source code for The Dark Descent and A Machine for Pigs has been released on Github for folks who want to take a crack at modifying the game. It's relatively rare for developers to post their game codes themselves, though sometimes proprietary code can make its way online via leaks. "This doesn't mean that the game is suddenly free," Amnesia developer Frictional Games said in a blog post. "It just means that people are free to use the source however they want as long as they adhere to the GPL3 licence. The game and all of its content is still owned by Frictional Games. Just like before."

Seeing how these classic games are built will also mean seeing things like flaws, and inefficiencies Frictional Games warned -- but it's all still functional and potentially useful to anyone learning game development. "I also hope this release can be of help to anyone wanting to create their own engine or just wanting to learn more about game programming," Frictional Games said. "While the code is not the greatest in places and the tech used is not the latest, it is a fully contained game engine in a fairly easy-to-understand package. It is also a testament that it is possible to do this sort of thing, even with a very limited team."

Researchers will be able to gain a deeper understanding of what's considered the world's oldest surviving (digital) computer after its long-lost user manual was unearthed. Engadget reports: The Z4, which was built in 1945, runs on tape, takes up most of a room and needs several people to operate it. The machine now takes residence at the Deutsches Museum in Munich, but it hasn't been used in quite some time. An archivist at ETH Zurich, Evelyn Boesch, discovered the manual among her father's documents in March, according to retired lecturer Herbert Bruderer. Rene Boesch worked with the Swiss Aeronautical Engineering Association, which was based at the university's Institute for Aircraft Statics and Aircraft Construction. The Z4 was housed there in the early 1950s.

Among Boesch's documents were notes on math problems the Z4 solved that were linked to the development of the P-16 jet fighter. "These included calculations on the trajectory of rockets, on aircraft wings, on flutter vibrations [and] on nosedive," Bruderer wrote in a Association of Computing Machinery blog post.

An anonymous reader quotes a report from Ars Technica: T-Mobile US CEO Mike Sievert yesterday fired back at AT&T and Verizon, saying the carriers' complaints about T-Mobile obtaining more spectrum licenses show that they are afraid of competition. "The duopolists are scrambling to block this new competition any way they can... Suddenly in the unfamiliar position of not having a dominant stranglehold on the wireless market, and preferring not to meet the competitive challenge in the marketplace, AT&T and Verizon are urging the FCC to slow T-Mobile down and choke off our ability to compete fairly for added radio spectrum," Sievert wrote in a blog post. As we wrote Monday, Verizon and AT&T have urged the Federal Communications Commission to impose limits on T-Mobile's ability to obtain more spectrum licenses. AT&T complained that T-Mobile's acquisition of Sprint allowed it to amass "an unprecedented concentration of spectrum."

Verizon has the most spectrum of any US carrier "by far" but "has the anti-competitive instincts and sheer audacity to complain that a much smaller T-Mobile has too much," Sievert wrote. "After holding massive spectrum advantages over T-Mobile and others for decades, Verizon and AT&T just can't stand the idea of anyone else being ahead of them or having a fair shot in an auction where they plan to use their financial might to do what they have always done -- dominate." Sievert also wrote that the 600MHz spectrum T-Mobile is leasing was previously controlled by AT&T. "AT&T had won at auction the spectrum that Columbia Capital is now leasing to T-Mobile and -- guess what -- AT&T decided it didn't want it and sold it to Columbia," Sievert wrote. "Verizon, the ringleader in opposing this lease, never bothered to even show up and bid for any 600MHz spectrum. In short, we have AT&T and Verizon seeking to block T-Mobile from using spectrum that AT&T decided to jettison, and Verizon had no interest in pursuing. Now both companies are seeking to block T-Mobile from putting this spectrum to use for the benefit of American consumers."

mabu writes: National Voter Registration Day, earmarked to call attention to encouraging more people to register to vote, is a pinnacle of many state's voter registration drives. Unfortunately in the state of Louisiana, its secretary of state Kyle Ardoin, decided this was a great time to shut the web site down for "scheduled maintenance." As a result, people who tried to register to vote online, on one of the most visible days of the registration drive, were denied the ability. "Ardoin's apparent decision to shut down the website raises concerns about ongoing efforts to suppress voter turnout during a heated election season in the midst of the COVID-19 pandemic," reports NOLA.com. New Orleans' mayor Latoya Cantrell called the move "Unacceptable."

"Ardoin, a Republican, has sparred with Democrat Gov. John Bel Edwards over absentee voting -- both in federal court and in the court of public opinion," NOLA.com adds. "A federal judge in Baton Rouge recently overturned efforts by Ardoin and GOP lawmakers to roll back previously expanded absentee voting in Louisiana. The judge's ruling, if it stands, would allow Louisiana voters to cast absentee ballots if they are concerned about COVID-related health risks associated with voting in-person. The ruling effectively reinstates the absentee voting rules that applied to the statewide primaries held in July and August, which came off without a whiff of 'voter fraud.'"

According to The Verge, Twitter says they will be testing voice DMs soon, after rolling out audio tweets for iOS in June. From the report: Brazil will be the first country included in that test. "We know people want more options for how they express themselves in conversations on Twitter -- both publicly and privately," [Alex Ackerman-Greenberg, product manager for direct messages at Twitter, said in a 20-second voice message].

Similar to voice tweets, voice messages have a bare-bones, simple interface: there's just a play / pause button, and the sender's avatar pulsates as the message plays. The product team designed an "in-line recording experience to make it easier to send these messages as part of the natural conversation flow," so that's one difference from the current audio tweets interface. There's a "report message" option in the event that someone misuses voice DMs, which is always a fair concern with private audio.

An anonymous reader quotes a report from CNET: Gavin Newsom has just announced plans to abolish the internal combustion engine by 2035. In an executive order announced Wednesday, Newsom said sales of internal-combustion passenger vehicles and light trucks would be banned by 2035. Instead of gas and diesel vehicles, the mandate calls for the sale of zero-emission vehicles. Medium- and heavy-duty trucks will be given an extra decade to comply. "This is the most impactful step our state can take to fight climate change," Newsom said. "Our cars shouldn't make wildfires worse -- and create more days filled with smoky air. Cars shouldn't melt glaciers or raise sea levels threatening our cherished beaches and coastlines."

Newsom also called on the state Legislature to ban the controversial oil extraction method known as fracking, "setting up what could be a contentious political fight when lawmakers reconvene in Sacramento next year," reports The Los Angeles Times.

Yesterday, U.S. Senators Rand Paul (R-KY), Ron Wyden (D-OR), and Gary Peters (D-MI) introduced the bipartisan ''Unplug the Internet Kill Switch Act of 2020'' (S. 4646), which would help protect Americans' First and Fourth Amendment rights by preventing a president from using emergency powers to unilaterally take control over or deny access to the internet and other telecommunications capabilities. Slashdot reader SonicSpike shares an excerpt from the announcement: In a World War II-era amendment to Section 706 of the Communications Act of 1934, Congress gave the Executive sweeping authority to put under direct government control or even shut down "any facility or station for wire communication" should a president "[deem] it necessary in the interest of the national security and defense" following a proclamation "that there exists a state or threat of war involving the United States." Cause for alarm over such power has only increased across the decades with the technological revolution, which has included email, text messages, and the internet, as well as the expansion of television, radio, and telephone networks.

The Unplug the Internet Kill Switch Act would amend Section 706 to strip out this "Internet Kill Switch" and help shut the door to broader government surveillance or outright control of our communications channels and some of Americans' most sensitive information. The legislation would also reassert a stronger balance of power during a national emergency between the Executive Branch and the people's representatives in Congress. You can read the "Unplug the Internet Kill Switch Act of 2020" here (PDF).

Plastic face shields are almost totally ineffective at trapping respiratory aerosols, according to modelling in Japan, casting doubt on their effectiveness in preventing the spread of coronavirus. From a report: A simulation using Fugaku, the world's fastest supercomputer, found that almost 100% of airborne droplets of less than 5 micrometres in size escaped through plastic visors of the kind often used by people working in service industries. One micrometre is one millionth of a metre. In addition, about half of larger droplets measuring 50 micrometres found their way into the air, according to Riken, a government-backed research institute in the western city of Kobe.

This week, senior scientists in Britain criticised the government for stressing the importance of hand-washing while placing insufficient emphasis on aerosol transmission and ventilation, factors that Japanese authorities have outlined in public health advice throughout the pandemic. As some countries have attempted to open up their economies, face shields are becoming a common sight in sectors that emphasise contact with the public, such as shops and beauty salons. Makoto Tsubokura, team leader at Riken's centre for computational science, said the simulation combined air flow with the reproduction of tens of thousand of droplets of different sizes, from under 1 micrometre to several hundred micrometres.

The September 20 deadline for a purported TikTok sale has already passed, but the parties involved have yet to settle terms on the deal. ByteDance and TikTok's bidders Oracle and Walmart presented conflicting messages on the future ownership of the app, confusing investors and users. Meanwhile, Beijing's discontent with the TikTok sale is increasingly obvious. From a report: China has no reason to approve the "dirty" and "unfair" deal that allows Oracle and Walmart to effectively take over TikTok based on "bullying and extortion," slammed an editorial published Wednesday in China Daily, an official English-language newspaper of the Chinese Communist Party. The editorial argued that TikTok's success -- a projected revenue of about a billion dollars by the end of 2020 -- "has apparently made Washington feel uneasy" and prompted the U.S. to use "national security as the pretext to ban the short video sharing app." The official message might stir mixed feelings within ByteDance, which has along the way tried to prove its disassociation from the Chinese authority, a precondition for the companies' products to operate freely in Western countries.

Last year, NASA had said that in four years, it would be landing the first woman ever on the moon, and returning to Earth's only natural satellite for the first time since 1972, through its Artemis programme. Now, in a release on September 22, NASA has shared an update outlining its plan, announcing a whopping $28 billion plan for the return to the lunar surface. From a report: The funds are all going to be used for the development of machinery; one billion dollars of the budget will go directly to the development of a commercial human lunar system that will take humans to the moon's surface. An allotment of $651 million will be used to support the Orion Spacecraft and the rocket that Boeing is building for the moon mission -- called the Space Launch System or SLS, on which NASA has already spent at least $11.9 billion.

The mission is named Artemis after the Greek goddess of the moon and the twin sister of Apollo. It's the antithesis to the NASA mission which last landed humans on the moon, Apollo 17. Only 12 humans, all male, have ever walked on the moon and they were all American, according to Bettina Inclan, NASA Communications Director. And with Artemis, they are finally planning to launch women on our satellite too. Currently, there are just 12 active women astronauts, excluding the five other female astronauts who graduated from training earlier this year. The crew for the 2024 mission, however, has not yet been named. According to NASA Administrator Jim Bridenstine, the first woman to walk on the moon would be somebody "who has been proven, somebody who has flown, somebody who has been on the International Space Station already."

America's most famous spy agency has a major competitor it can't quite seem to beat: Silicon Valley. From a report: The CIA has long been a place cutting-edge technology is researched, developed, and realized -- and it wants to lead in fields like artificial intelligence and biotechnology. However, recruiting and retaining the talent capable of building these tools is a challenge on many levels, especially since a spy agency can't match Silicon Valley salaries, reputations, and patents. The agency's solution is CIA Labs, a new skunkworks that will attempt to recruit and retain technical talent by offering incentives to those who work there.

Under the new initiative, announced today, CIA officers will be able for the first time to publicly file patents on the intellectual property they work on -- and collect a portion of the the profits. The agency will take the rest of the balance. Dawn Meyerriecks, who heads the agency's science and technology directorate, says the best-case scenario is that the agency's research and development could end up paying for itself. "This is helping maintain US dominance, particularly from a technological perspective," says Meyerriecks. "That's really critical for national and economic security. It also democratizes the technology by making it available to the planet in a way that allows the level of the water to rise for all."

Intel today announced the launch of new products tailored to edge computing scenarios like digital signage, interactive kiosks, medical devices, and health care service robots. From a report: The 11th Gen Intel Core Processors, Atom x6000E Series, Pentium, Celeron N, and J Series bring new AI security, functional safety, and real-time capabilities to edge customers, the chipmaker says, laying the groundwork for innovative future applications. Intel expects the edge market to be a $65 billion silicon opportunity by 2024. The company's own revenue in the space grew more than 20% to $9.5 billion in 2018. And according to a 2020 IDC report, up to 70% of all enterprises will process data at the edge within three years. To date, Intel claims to have cultivated an ecosystem of more than 1,200 partners, including Accenture, Bosch, ExxonMobil, Philips, Verizon, and ViewSonic, with over 15,000 end customer deployments across "nearly every industry."

The 11th Gen Core processors -- which Intel previewed in early September -- are enhanced for internet of things (IoT) use cases requiring high-speed processing, computer vision, and low-latency deterministic processing, the company says. They bring an up to 23% performance gain in single-threaded workloads, a 19% performance gain in multithreaded workloads, and an up to 2.95 times performance gain in graphics workloads versus the previous generation. New dual video decode boxes allow the processors to ingest up to 40 simultaneous video streams at 1080p up to 30 frames per second and output four channels of 4K or two channels of 8K video. According to Intel, the combination of the 11th Gen's SuperFin process improvements, miscellaneous architectural enhancements, and Intel's OpenVINO software optimizations translates to 50% faster inferences per second compared with the previous 8th Gen processor using CPU mode or up to 90% faster inferences using the processors' GPU-accelerated mode.

Google has announced that Flutter, its open source UI development kit for building cross-platform software from the same codebase, is finally available for Windows apps in alpha. From a report:For the world's leading desktop operating system with some 1 billion installations of Windows 10 alone, this has been a long time coming. Flutter's alpha incarnation was initially launched at Google's I/O developer conference back in 2017, before arriving in beta less than a year later. In its original guise, Flutter was designed for Android and iOS app development, but it has since expanded to cover the web, MacOS, and Linux, which are currently available in various alpha or beta iterations. Developers have had to consider unique platform-specific factors when designing for the desktop or mobile phones, such as different screen sizes and how people interact with their devices. On smartphones, people typically use touch and swipe-based gestures, while keyboards and mice are commonly used on PCs and laptops. This means Flutter has had to expand its support to cover the additional inputs.

Software engineer Cal Paterson writes: Mozilla recently announced that they would be dismissing 250 people. That's a quarter of their workforce so there are some deep cuts to their work too. The victims include: the MDN docs (those are the web standards docs everyone likes better than w3schools), the Rust compiler and even some cuts to Firefox development. Like most people I want to see Mozilla do well but those three projects comprise pretty much what I think of as the whole point of Mozilla, so this news is a a big let down. The stated reason for the cuts is falling income. Mozilla largely relies on "royalties" for funding. In return for payment, Mozilla allows big technology companies to choose the default search engine in Firefox - the technology companies are ultimately paying to increase the number of searches Firefox users make with them. Mozilla haven't been particularly transparent about why these royalties are being reduced, except to blame the coronavirus. I'm sure the coronavirus is not a great help but I suspect the bigger problem is that Firefox's market share is now a tiny fraction of its previous size and so the royalties will be smaller too - fewer users, so fewer searches and therefore less money for Mozilla.

The real problem is not the royalty cuts, though. Mozilla has already received more than enough money to set themselves up for financial independence. Mozilla received up to half a billion dollars a year (each year!) for many years. The real problem is that Mozilla didn't use that money to achieve financial independence and instead just spent it each year, doing the organisational equivalent of living hand-to-mouth. Despite their slightly contrived legal structure as a non-profit that owns a for-profit, Mozilla are an NGO just like any other. In this article I want to apply the traditional measures that are applied to other NGOs to Mozilla in order to show what's wrong. These three measures are: overheads, ethics and results.

America is now under siege by climate change in ways that scientists have warned about for years. But there is a second part to their admonition: Decades of growing crisis are already locked into the global ecosystem and cannot be reversed. From a report: This means the kinds of cascading disasters occurring today -- drought in the West fueling historic wildfires that send smoke all the way to the East Coast, or parades of tropical storms lining up across the Atlantic to march destructively toward North America -- are no longer features of some dystopian future. They are the here and now, worsening for the next generation and perhaps longer, depending on humanity's willingness to take action. "I've been labeled an alarmist," said Peter Kalmus, a climate scientist in Los Angeles, where he and millions of others have inhaled dangerously high levels of smoke for weeks. "And I think it's a lot harder for people to say that I'm being alarmist now." Last month, before the skies over San Francisco turned a surreal orange, Death Valley reached 130 degrees Fahrenheit, the highest temperature ever measured on the planet. Dozens of people have perished from the heat in Phoenix, which in July suffered its hottest month on record, only to surpass that milestone in August.

Conversations about climate change have broken into everyday life, to the top of the headlines and to center stage in the presidential campaign. The questions are profound and urgent. Can this be reversed? What can be done to minimize the looming dangers for the decades ahead? Will the destruction of recent weeks become a moment of reckoning, or just a blip in the news cycle? The Times spoke with two dozen climate experts, including scientists, economists, sociologists and policymakers, and their answers were by turns alarming, cynical and hopeful. "It's as if we've been smoking a pack of cigarettes a day for decades" and the world is now feeling the effects, said Katharine Hayhoe, a climate scientist at Texas Tech University. But, she said, "we're not dead yet." Their most sobering message was that the world still hasn't seen the worst of it. Gone is the climate of yesteryear, and there's no going back. The effects of climate change evident today are the results of choices that countries made decades ago to keep pumping heat-trapping greenhouse gases into the atmosphere at ever-increasing rates despite warnings from scientists about the price to be paid.
