Microsoft has officially announced a new "moving platform" feature for the HoloLens 2, which is designed to let the augmented reality headset work in places like cars. The Verge reports: It addresses a long-standing HoloLens issue of moving environments confusing the headset's sensors. The enhancement was developed in collaboration with Volkswagen, which has been experimenting with using the headset as a heads-up display in its vehicles. As Microsoft's blog post explains, its augmented reality headset tracks movement using a combination of camera sensors and an inertial measurement unit (which typically includes accelerometers and gyroscopes). But in a car, the readings from these two sensors can conflict; the headset senses movement but sees a static environment. In other words, it was getting car sick.

That's what VW discovered after it started investigating the use of augmented reality headsets to teach drivers how to get around a racetrack faster. It started collaborating with Microsoft to fix the sensor problem in 2018, and, eventually, the two developed a prototype system that allowed a car to display real-time information on a connected headset. The system allows virtual objects to be placed both inside and outside of the vehicle. One image released by Microsoft (above) shows the HoloLens 2 projecting a virtual map onto the dashboard of a car, with navigation arrows appearing ahead at key intersections. A second shows it alerting the driver to an upcoming pedestrian crossing.

Venture capital returns have puked this year. The next dangerous stage is investor outflows. Financial Times: Back in the halcyon days of ... early 2021, it looked like venture capital was the hottest game in town. Hedge funds were piling in. Even private equity firms were getting involved in early-stage company investing. Investors loved the combination of fat returns and the lack of volatility in private markets. But the VC cycle now looks like it has hit a sudden stop. Refinitiv's venture capital index, which uses the performance of individual VC portfolios and listed stocks to mimic the performance of the broader industry, tanked another 24.2 per cent in April, taking its 2022 loss to a comically bad 45.8 per cent (NB, the Nasdaq is "only" down 19.7 per cent YTD).

That is comfortably its worst monthly performance since worst of the dotcom bust two decades ago. Of course, a lot of venture capital funds are unlikely to be marking down their books to anywhere near these levels. Some may just be doing better than others (performance persistence is higher in VC than in any other investment industry), but the advantage of private market accounting and negotiated and infrequent funding rounds means that valuations and returns can be massaged a little. There might even be a bit of schadenfreude at the pain suffered by Tiger Global lately, which many venture capitalists saw as an annoyingly uppity interloper-dilettante in Silicon Valley. But the reality is that the bottom has dropped out of tech stock valuations lately -- both public and private -- and anyone who is not marking down their positions heavily might actually unnerve investors more than assuage them.

CNN profiles Bellingcat, a Netherlands-based investigative group specializing in "open-source intelligence". And investigator Christo Grozev tells CNN that authoritarian governments make their work easier, because "they love to gather data, comprehensive data, on ... what they consider to be their subjects, and therefore there's a lot of centralized data."

"And second, there's a lot of petty corruption ... within the law enforcement system, and this data market thrives on that." Billions have been spent on creating sophisticated encrypted communications for the military in Russia. But most of that money has been stolen in corrupt kickbacks, and the result is they didn't have that functioning system... It is shocking how incompetent they are. But it was to be expected, because it's a reflection of 23 years of corrupt government.
Interestingly there's apparently less corruption in China — though more whistleblowers. But Bellingcat's first investigation involved the 2014 downing of a Boeing 777 over eastern Ukraine that killed 283 passengers. (The Dutch Safety Board later concluded it was downed by a surface-to-air missile launched from pro-Russian separatist-controlled territory in Ukraine.) "At that time, a lot of public data was available on Russian soldiers, Russian spies, and so on and so forth — because they still hadn't caught up with the times, so they kept a lot of digital traces, social media, posting selfies in front of weapons that shoot down airliners. That's where we kind of perfected the art of reconstructing a crime based on digital breadcrumbs..."

"By 2016, it was no longer possible to find soldiers leaving status selfies on the internet because a new law had been passed in Russia, for example, banning the use of mobile phones by secret services and by soldiers. So we had to develop a new way to get data on government crime. We found our way into this gray market of data in Russia, which is comprised of many, many gigabytes of leaked databases, car registration databases, passport databases. Most of these are available for free, completely freely downloadable from torrent sites or from forums and the internet." And for some of them, they're more current. You actually can buy the data through a broker, so we decided that in cases when we have a strong enough hypothesis that a government has committed the crime, we should probably drop our ethical boundaries from using such data — as long as it is verifiable, as long as it is not coming from one source only but corroborated by at least two or three other sources of data. That's how we develop it. And the first big use case for this approach was the ... poisoning of Sergei and Yulia Skripal in 2018 (in the United Kingdom), when we used this combination of open source and data bought from the gray market in Russia to piece together who exactly the two poisoners were. And that worked tremendously....

It has been what I best describe as a multilevel computer game.... [W]hen we first learned that we can get private data, passport files and residence files on Russian spies who go around killing people, they closed the files on those people. So every spy suddenly had a missing passport file in the central password database. But that opened up a completely new way for us to identify spies, because we were just able to compare older versions of the database to newer versions. So that allowed us to find a bad group of spies that we didn't even know existed before.

The Russian government did realize that that's maybe a bad idea to hide them from us, so they reopened those files but just started poisoning data. They started changing the photographs of some of these people to similar looking, like lookalikes of the people, so that they confused us or embarrass us if we publish a finding but it's for the wrong guy. And then we'll learn how to beat that.
When asked about having dropped some ethical boundaries about data use, Grozev replies "everything changes. Therefore, the rules of journalism should change with the changing times." "And it's not common that journalism was investigating governments conducting government-sanctioned crimes, but now it's happening." With a country's ruler proclaiming perpetual supreme power, "This is not a model that traditional journalism can investigate properly. It's not even a model that traditional law enforcement can investigate properly." I'll give an example. When the British police asked, by international agreement, for cooperation from the Russian government to provide evidence on who exactly these guys were who were hanging around the Skripals' house in 2018, they got completely fraudulent, fake data from the Russian government....

So the only way to counter that as a journalist is to get the data that the Russian government is refusing to hand over. And if this is the only way to get it, and if you can be sure that you can prove that this is valid data and authentic data — I think it is incumbent on journalists to find the truth. And especially when law enforcement refuses to find the truth because of honoring the sovereign system of respecting other governments.
It was Bellingcat that identified the spies who's poisoned Russian opposition leader Alexey Navalny. CNN suggests that for more details on their investigation, and "to understand Vladimir Putin's stranglehold on power in Russia, watch the new film Navalny which premieres Sunday at 9 p.m. ET on CNN."

The movie's tagline? "Poison always leaves a trail."

Anomaly Six, a secretive government contractor, claims to monitor the movements of billions of phones around the world and unmask spies with the press of a button. Reader BeerFartMoron shares a report: In the months leading up to Russia's invasion of Ukraine, two obscure American startups met to discuss a potential surveillance partnership that would merge the ability to track the movements of billions of people via their phones with a constant stream of data purchased directly from Twitter. According to Brendon Clark of Anomaly Six -- or "A6" -- the combination of its cellphone location-tracking technology with the social media surveillance provided by Zignal Labs would permit the U.S. government to effortlessly spy on Russian forces as they amassed along the Ukrainian border, or similarly track Chinese nuclear submarines. To prove that the technology worked, Clark pointed A6's powers inward, spying on the National Security Agency and CIA, using their own cellphones against them.

Virginia-based Anomaly Six was founded in 2018 by two ex-military intelligence officers and maintains a public presence that is scant to the point of mysterious, its website disclosing nothing about what the firm actually does. But there's a good chance that A6 knows an immense amount about you. The company is one of many that purchases vast reams of location data, tracking hundreds of millions of people around the world by exploiting a poorly understood fact: Countless common smartphone apps are constantly harvesting your location and relaying it to advertisers, typically without your knowledge or informed consent, relying on disclosures buried in the legalese of the sprawling terms of service that the companies involved count on you never reading.

As Facebook/Meta faces rising pressure in west, it is investing in digital infrastructure elsewhere. From a report: When government officials in the southern Nigerian state of Edo set about radically improving poor internet access for its population of 4 million, they didn't have to look far for help. MainOne, a company responsible for laying a vast network of fibre-optic cables across west Africa, was an obvious partner. Another, perhaps less obvious one, was Facebook. A joint agreement was signed to install fibre-optic cables running across the state's capital, Benin City. Since 2019, 400km (250 miles) of cables have been laid in Edo, about a quarter via the partnership between the two companies and the government. "Obviously, Facebook isn't really a digital infrastructure company, but they invested in these cables," said Emmanuel Magnus Eweka, who worked as a senior government official for the Edo government until last September. In recent years, as Facebook has come under rising legislative pressure in the west, the company has increased its focus on Africa, particularly in countries where the regulatory and legislative environment tends to be much looser.

The combination of weak and expensive internet coverage for most of Nigeria's fast-growing population of more than 200 million people has meant that companies hoping to tap into a potential goldmine of new users -- and their data -- have sought to invest in the business of helping those potential users get online in the first place. "To make internet data more affordable, Facebook needs to build infrastructures that are almost free," Eweka said. "In fact, I'd say Facebook actually loses in terms of making money out of those cables. But then they gain it back on the user data that they will generate, and obviously that has huge potential in a country like Nigeria."

Russia is adapting to a world where it no longer has access to many technologies abroad with the development of a new supercomputer platform that can use foreign x86 processors such as Intel's in combination with the country's homegrown Elbrus processors. The Register reports: The new supercomputer reference system, dubbed "RSK Tornado," was developed on behalf of the Russian government by HPC system integrator RSC Group, according to an English translation of a Russian-language press release published March 30. RSC said it created RSK Tornado as a "unified interoperable" platform to "accelerate the pace of important substitution" for HPC systems, data processing centers and data storage systems in Russia. In other words, the HPC system architecture is meant to help Russia quickly adjust to the fact that major chip companies such as Intel, AMD and TSMC -- plus several other technology vendors, like Dell and Lenovo -- have suspended product shipments to the country as a result of sanctions by the US and other countries in reaction to Russia's invasion of Ukraine.

RSK Tornado supports up to 104 servers in a rack, with the idea being to support foreign x86 processors (should they come available) as well as Russia's Elbrus processors, which debuted in 2015. The hope appears to be the ability for Russian developers to port HPC, AI and big data applications from x86 architectures to the Elbrus architecture, which, in theory, will make it easier for Russia to rely on its own supply chain and better cope with continued sanctions from abroad. RSK Tornado systems software is RSC proprietary and is currently used to orchestrate supercomputer resources at the Interdepartmental Supercomputer Center of the Russian Academy of Sciences, St Petersburg Polytechnic University and the Joint Institute for Nuclear Research. RSC claims to have also developed its own liquid-cooling system for supercomputers and data storage systems, the latter of which can use Elbrus CPUs too.

An anonymous reader quotes a report from New Atlas: One of the first products made using a novel animal-free egg white is now available in the United States. The unique macarons are the first to be made with an egg white protein that comes from engineered yeast, designed to be indistinguishable from what is found in chicken eggs. The Every Company, founded in 2014 under the name Clara Foods, is one of several food technology companies working to create real animal-free proteins using a method called precision fermentation. The idea behind the process is to break down certain animal products, such as milk and eggs, to their molecular components and then use microorganisms to produce those components. Earlier this year the first cow-free dairy milk using this method hit supermarket shelves in the United States. That product was created using whey proteins from engineered fungus, while other companies are working on similar dairy products using engineered yeast to produce the desired milk proteins.

The Every Company has spent the last few years focusing on using the same technique to produce chicken-free egg whites, working with engineered yeast to produce proteins found in egg whites. The company has not disclosed the specific combination of proteins used to create its final egg white product, however it is likely ovalbumin -- the primary protein component in egg whites -- plays a strong role in the recipe. Arturo Elizondo, CEO of Every Company, said the new egg white product functions exactly like a chicken-derived egg white. It whips, aerates and bakes in ways identical to traditional egg whites, and the company has teamed up with San Francisco-based bakery Chantal Guillon to launch the product in a line of iconic French macarons. The chicken-free egg white is the third animal-free product created by the Every Company. Its first fully commercialized product was an animal-free pepsin, launched in early 2021.

Covid-19 patients who have been hospitalised should also be routinely tested for flu, researchers have said. The call was made after the publication of a paper in the medical journal the Lancet that revealed having both conditions more than doubles the risk of a patient dying. From a report: Scientists also discovered that individuals who had contracted both Sars-CoV-2, the virus that causes Covid-19, and influenza viruses were more than four times more likely to require ventilation support and 2.4 times more likely to die than if they just had Covid-19. "We found that the combination of Covid-19 and flu viruses is particularly dangerous," said Professor Kenneth Baillie of Edinburgh University. "We expect that Covid-19 will circulate with flu, increasing the chance of co-infections. That is why we should change our testing strategy for Covid-19 patients in hospital and test for flu much more widely."

The study looked at more than 305,000 hospitalised patients with Covid-19 and involved researchers from Edinburgh University, Liverpool University, Imperial College London and Leiden University in the Netherlands. A total of 6,965 patients were found to have had Covid-19, while 227 also had the influenza virus. These individuals experienced significantly more severe outcomes, researchers found. "We were surprised that the risk of death more than doubled when people were infected by both flu and Covid-19 viruses," said Professor Calum Semple of Liverpool University. "It is now very important that people get fully vaccinated and boosted against both viruses, and not leave it until it is too late."

Companies including Highland Electric and Thomas Built have fleet-as-a-service offerings for U.S. school districts that struggle with the high upfront costs of electric school buses and the charging equipment needed to keep them running. Jeff St. John from Canary Media writes: On Thursday, the Massachusetts-based startup and the North Carolina-based school bus manufacturer announced a plan to offer "electric school bus subscriptions through 2025 at prices that put them at cost parity with diesel." This is essentially a nationwide extension of Highland Electric's "turnkey solutions provider" business model, backed by a big bus maker as its partner. Highland provides the buses and charging infrastructure, pays for the electricity to charge them, covers maintenance costs and manages the other complexities of going electric. The school district or transit authority pays an all-inclusive subscription fee, one that's structured to be lower than its current budget for owning, fueling and maintaining its existing diesel fleets.

Highland, which has raised $253 million in venture capital funding, has projects in 17 states and two Canadian provinces, including one of the largest single electric school bus deployments in the U.S., in Montgomery County, Maryland, outside Washington, D.C. While most of its projects have started small, CEO Duncan McIntyre sees the Montgomery County project -- now at 25 electric buses and set to expand to 326 over the next four years -- as the model for the future. "We are in the business of helping communities that want to complete a full fleet-electrification effort," McIntyre said in an interview. "They don't have to commit to that upfront -- but there's usually an interest in going beyond a few-vehicles pilot."

Other companies are also pulling together private-sector financing to tackle this public-sector market. Nuvve, a publicly traded EV-charging and vehicle-to-grid provider, has formed a financing joint venture that's teamed up with school bus manufacturer Blue Bird Corp. to offer similar electric bus leasing and infrastructure offerings with school districts in California, Colorado, Illinois and other states. And Canadian EV maker Lion Electric has teamed up with Zum, a San Francisco-based startup offering transportation-as-a-service for a number of school districts, in a project aiming at replacing half of Oakland, California's school buses with electric models in the coming year. Such large-scale electric bus projects remain the exception rather than the rule, however. Out of the roughly 500,000 school buses in the U.S., only about 0.2 percent -- just over 1,000 -- were electric as of the end of 2021, according to data from the World Resources Institute's Electric School Bus Initiative. And of the 354 U.S. school districts that have committed to buying electric buses, only 28 plan to deploy 10 or more, according to WRI data.

This relatively low rate of adoption is bound to accelerate as the economics of electric school buses grow more attractive, however. A 2020 study (PDF) conducted by Atlas Public Policy for Washington state indicated that falling battery costs and rising manufacturing volumes should bring electric school buses within total-cost-of-ownership (TCO) parity with fossil-fueled buses by 2030. Total cost of ownership -- a metric that bundles long-term fueling, operating, maintenance and insurance costs and a vehicle's residual value into one single figure -- can be brought down with structures that reduce costs or open up revenue-generating opportunities for the fleets in question, Nick Nigro, Atlas Public Policy's founder, said in an interview. The right combination of structures could allow electric buses to come into TCO parity with diesel buses as soon as 2025, he said.

Winamp will sell a non-fungible token (NFT) linked to its media player's original 1997 graphical skin, becoming the latest company to blend nostalgia and crypto. The Verge reports: Winamp will put the NFT up for auction through OpenSea between May 16th and May 22nd, followed by a separate sale of 1997 total NFTs based on 20 artworks derived from the original skin. The proceeds will go to the Winamp Foundation, which promises to donate them to charity projects, starting with the Belgian nonprofit Music Fund.

The NFT sale appears to be a combination of a publicity move and a fundraising effort. Winamp is sourcing the derivative art NFTs by asking artists to submit Winamp-based works between now and April 15th, then giving selected artists 20 percent of the proceeds from each sale of their image as an NFT. Nineteen of the pieces will sell in editions of 100 copies, and the remaining one will have 97; they'll all sell for 0.08 Ethereum -- around $210 at current exchange rates. The artists will get 10 percent of any royalties on later sales, where the seller will set their own price.

Winamp's head of business development Thierry Ascarez tells The Verge that buyers will get a blockchain token linked to an image of either the original skin seen above or one of its derivatives, which is a common setup for NFTs. Buyers will have the right to "copy, reproduce, and display" the image, but they won't own the copyright. Likewise, selected artists will agree to transfer all intellectual property for their work to Winamp, according to a page of terms and conditions (PDF).

Cogent Communications, one of the world's largest internet intercontinental backbone providers, has cut ties with Russian customers over its invasion of Ukraine. The Verge reports: In a letter to Russian customers obtained by The Washington Post, Cogent cited "economic sanctions" and "the increasingly uncertain security situation" as the motives behind its total shutdown in the country. Cogent similarly told The Verge that it "terminated its contracts" with Russian customers in compliance with the European Union's move to ban Russian state-backed media outlets.

As Doug Madory, an internet analyst at network tracking company Kentik points out... unplugging Russia from Cogent's global network will likely result in slower connectivity, but won't completely disconnect Russians from the internet... Traffic from Cogent's former customers will instead fall back on other backbone providers in the country, potentially resulting in network congestion. There isn't any indication as to whether other internet backbone providers will also suspend services in Russia.

Digital rights activists have criticized Cogent's decision to disconnect itself from Russia, arguing that it could prevent Russian civilians from accessing credible information about the invasion. "Cutting Russians off from internet access cuts them off from sources of independent news and the ability to organize anti-war protests," Eva Galperin, the director of cybersecurity at the digital rights group Electronic Frontier Foundation, said on Twitter....

Cogent's goal is to prevent the Russian government from using the company's networks for cyberattacks and propaganda, The Post reports.
The Post argues that on a larger scale,"these moves bring Russia closer to the day when its online networks face largely inward, their global connections weakened, if not cut off entirely." "I am very afraid of this," said Mikhail Klimarev, executive director of the Internet Protection Society, which advocates for digital freedoms in Russia. "I would like to convey to people all over the world that if you turn off the Internet in Russia, then this means cutting off 140 million people from at least some truthful information. As long as the Internet exists, people can find out the truth. There will be no Internet — all people in Russia will only listen to propaganda...."

[E]ven two weeks ago, Russia's Internet was comparatively free and integrated into the larger online world, allowing civil society to organize, opposition figures to deliver their messages and ordinary Russians to gain ready access to alternative sources of news in an era when Putin was strangling his nation's free newspapers and broadcast stations.... Patrick Boehler, head of digital strategy at Radio Free Europe, said CrowdTangle data showed that independent news stories in the Russian language worldwide were getting shared many more times on social media than stories from state-run media. He said that once the Kremlin lost control of the narrative, it would have been hard to regain.

Now the last independent journalistic outposts are gone, and the Internet options are increasingly constricted through a combination of forces — all spurred by war in Ukraine but coming from both within and outside Russia.... Government censors also blocked access to the BBC, Voice of America, Radio Free Europe/Radio Liberty and Deutsche Welle, as well as major Ukrainian websites. The BBC, CNN and other international news organizations said they were suspending reporting in Russia because of a new law that could result in 15 years of prison for publishing what government officials deem false news on the war.
Meanwhile, Politico reminds us that even Oracle has shut down its Russian cloud service operations. Laura Manley, the executive director of Harvard University's Shorenstein Center on Media, Politics and Public Policy, said Russia is creating a perfect situation to control its narrative and limit outside coverage of its Ukrainian invasion by Western social media sources. "You have the lack of eyewitness information because you have critical infrastructure being shut off," she said. "So it's sort of a worst case scenario in terms of getting real-time accurate information."

A research and development arm of the U.S. Department of Homeland Security announced last month it has been working with the Philadelphia-based company Ghost Robotics to develop a robot dog for the border. Now a small group of Latino U.S. House members recently expressed "extreme concern" about the plan. From a report: A letter obtained by Axios Latino shows that U.S. Reps. Veronica Escobar (D-Texas), Adriano Espaillat (D-NY) and Nanette Diaz Barragan (D-CA) are seeking a meeting with U.S. Customs and Border Protection about the robots. In the letter, the House members write that the term "robot dogs" is a "disingenuous moniker that attempts to soft-pitch the use of this technology."

"It downplays the threat the robots pose to migrants arriving at our southern border and the part they play in a long history of surveillance and privacy violations in our border communities." The letter also said they are concerned that the robot dogs will inevitably result in armed patrols and that they could critically injure, or even kill, migrants or American citizens. Robots used in combination with drones, facial recognition technology and license plate readers, pose civil liberties risks, the letter said.

An anonymous reader quotes a report from ZDNet: A group of Brazilian researchers has created a web platform that is able to identify false information online in an automated manner. Developed by academics at the Center for Mathematical Sciences Applied to Industry (CeMEAI), the system uses a combination of statistical models and machine learning techniques to establish whether a specific content in Brazilian Portuguese is likely to be false. Initial tests suggest the platform is able to detect fake news with a 96% accuracy. The CeMEAI is a research center based in the mathematics and computer science department of the University of Sao Paulo, in the Sao Paulo state city of Sao Carlos. The center is supported by grants from the Sao Paulo Research Agency (FAPESP). In an interview with FAPESP's news agency, project coordinator and technology transfer director Francisco Louzada Neto said the goal of the project is "to offer society an additional tool to identify, not only subjectively, whether a news item is false or not."

The system uses statistical methods to analyze writing characteristics, such as words used or more frequently used grammatical classes. These are then fed into a machine learning-based classifier, which is able to distinguish patterns of language, vocabulary and semantics of fake and real news, and automatically infer whether the content submitted to the platform is false. The models were trained with a massive database of real and false news and were exposed to the vocabulary used in over 100,000 articles published over the last five years. The researchers will aim to use the false news related to the upcoming presidential elections, as well as content related to the Covid-19 pandemic to further calibrate the models. The researchers also commented on the potential risks of the system in the interview, including the potential that the system could be used by fake news creators to assess the potential for false content to pass for real before it is published. "That's a risk we're going to have to deal with," Louzada noted.

An anonymous reader quotes a report from CNBC: Binance, the world's biggest cryptocurrency exchange, is making a $200 million strategic investment in Forbes, the 104-year-old magazine and digital publisher, CNBC has learned. The funds will help Forbes execute on its plan to merge with a publicly traded special purpose acquisition company, or SPAC, in the first quarter, according to people with knowledge of the deal. Binance will replace half of the $400 million in commitments from institutional investors announced by Forbes in August, said the people. That would make Binance one of the top two biggest owners of Forbes, which will be listed on the New York Stock Exchange under the ticker FRBS, the people said. The crypto company will also get two directors out of nine total board seats, they said. The move shows the increasing real-world influence of the crypto sector, which has seen surging valuations and minted a new class of billionaires amid global interest in digital assets. While crypto companies have gone public, affixed their names to sports arenas and flooded airwaves with celebrity endorsements, this is the sector's first big investment in a traditional U.S. media property.

The investment by Binance, founded barely five years ago, is an indication that Zhao believes content generation will be a growth area for Web 3.0 development. Web 3.0 refers to a more decentralized version of the internet that uses the blockchain, which also underpins cryptocurrencies and non-fungible tokens, or NFTs. [...] The company approached Forbes, which had been weighing options including an outright sale, after identifying three media and content platforms for potential investment, said the people. Crypto insiders say they expect a deluge of deals this year as companies deploy the enormous sums of money raised in recent fundraising rounds.

An anonymous reader quotes a report from Gizmodo: Researchers in Canada say they've come up with two simple physical techniques to help prevent a common cause of dizziness and fainting. In a small trial, they found that these maneuvers, which involve nothing more than moving your lower limbs, could effectively reduce the symptoms of initial orthostatic hypotension (IOH), a condition that temporarily leaves people light headed when they stand up. [...] Though many people can experience IOH without ever registering it as a big problem, some sufferers can have repeated or severe enough episodes of IOH that it routinely affects their daily functioning. Study author Satish Raj, a heart rhythm cardiologist at the University of Calgary, and his colleagues have often seen these sorts of patients at their dysautonomia and fainting clinic. And they wondered if there was something more they could offer these patients besides lifestyle changes like drinking more water or medications.

As he explains it, when people stand up, blood flow normally shifts downward to below our chest. But in IOH, this change seems to be accompanied by a reflex, triggered by the activation of muscles as we stand up, that causes blood vessels to open widely -- and it's this combination that then causes the rapid but temporary drop in blood pressure. Based on Raj's team's earlier work, as well as other research, they hypothesized that people with IOH could short-circuit this process by activating the reflex early or by tensing the lower limb muscles as they stood, somewhat mitigating the blood pressure drop.

To test this out, they recruited 22 volunteers with IOH to try out both of the techniques they developed. One method involved pre-activating the muscles behind the reflex from a sitting position, done simply by raising the knees one at a time for up to 30 seconds. The other asked people to stand and then tense up their lower limbs, by crossing their legs and clenching their thighs and butt. As a control, the volunteers would also stand up normally. Compared to the control condition, on measures of both the volunteers' circulation and their self-reported symptoms, people's IOH improved after doing either technique. And Raj's patients in the clinic have anecdotally reported similar success after adopting the strategies. The team's findings were published Wednesday in the journal Heart Rhythm.

An anonymous reader quotes a report from Motherboard: A section of the New York Police Department (NYPD) focused on intelligence gathering received a demo of NSO Group's controversial Pegasus spyware product, according to an email obtained by Motherboard. The news provides more insight into Israeli company NSO Group's push into the surveillance market in the United States, and specifically its pitching of the company's technology to American police forces. The findings come after the New York Times reported that the FBI bought a Pegasus license in 2019 for evaluation purposes.

"There will be a demo of the attached investigative software at the Rutgers School of Criminal Justice," James Sheehan, a program manager from the Northern New Jersey-Newark/Jersey City UASI, wrote in the August 2015 email. The UASI is the Urban Area Security Initiative, a program administered by the Department of Homeland Security which brings together bodies from law enforcement, fire service, public health, and more to address threats of terrorism and other issues. "The audience is the UASI/CorrStat region and NYPD intel," Sheehan continued. Recipients on Sheehan's email inviting people to attend included representatives from the Bergen County Prosecutor's Office, Jersey City's public safety agency, and the Paterson Police Department, a city of just over 150,000.

Attached to Sheehan's email was a brochure for Pegasus, NSO Group's hacking product, which advertised the tool's ability to obtain a target's calls, contacts, emails, WhatsApp messages, track their location, and more. The brochure contains a logo for WestBridge, NSO Group's North American branch. "Turn Your Target's Smartphone into an Intelligence Gold Mine," the Pegasus brochure reads. "NYPD intel" likely refers to the NYPD's Intelligence Bureau. Its mission is to "detect and disrupt criminal and terrorist activity through the use of intelligence-led policing. In combination with traditional policing methods, uniformed officers and civilian analysts in the Intelligence Bureau collect and analyze information from a variety of sources in order to advance criminal and terrorist investigations," according to the NYPD's website.

Three research scientists at DeepMind Technologies teamed up with former world chess champion Vladimir Kramnik to "explore what variations of chess would look like at superhuman level," according to their new article in Communications of the ACM. Their paper argues that using neural networks and advanced reinforcement learning algorithms can not only surpass all human knowledge of chess, but also "allow us to reimagine the game as we know it...."

"For example, the 'castling' move was only introduced in its current form in the 17th century. What would chess have been like had castling not been incorporated into the rules?"

AfterAlphaZero was trained to play 9 different "variants" of chess, it then played 11,000 games against itself, while the researchers assessed things like the number of stalemates and how often the special new moves were actually used. The variations tested:

- Castling is no longer allowed
- Castling is only allowed after the 10th move
- Pawns can only move one square
- Stalemates are a win for the attacking side (rather than a draw)
- Pawns have the option of moving two squares on any turn (and can also be captured en passant if they do)
- Pawns have the option of moving two squares -- but only when they're in the second or third row of squares. (After which they can be captured en passant )
- Pawns can move backwards (except from their starting square).

- It's possible to capture your own pieces.


"The findings of our quantitative and qualitative analysis demonstrate the rich possibilities that lie beyond the rules of modern chess."

AlphaZero's ability to continually improve its understanding of the game, and reach superhuman playing strength in classical chess and Go, lends itself to the question of assessing chess variants and potential variants of other board games in the future. Provided only with the implementation of the rules, it is possible to effectively simulate decades of human experience in a day, opening a window into top-level play of each variant. In doing so, computer chess completes the circle, from the early days of pitting man vs. machine to a collaborative present of man with machine, where AI can empower players to explore what chess is and what it could become....

The combination of human curiosity and a powerful reinforcement learning system allowed us to reimagine what chess would have looked like if history had taken a slightly different course. When the statistical properties of top-level AlphaZero games are compared to classical chess, a number of more decisive variants appear, without impacting the diversity of plausible options available to a player....

Taken together, the statistical properties and aesthetics provide evidence that some variants would lead to games that are at least as engaging as classical chess. "Chess's role in artificial intelligence research is far from over..." their article concludes, arguing that AI "can provide the evidence to take reimagining to reality."

sciencehabit shares a report from Science.org: When Hunga Tonga-Hunga Ha'apai, a mostly submerged volcanic cauldron in the South Pacific Ocean, exploded on January 15, it unleashed a blast perhaps as powerful as the world's biggest nuclear bomb, and drove tsunami waves that crashed into Pacific shorelines. But 3 hours or so before their arrival in Japan, researchers detected the waves of another small tsunami. Even stranger, tiny tsunami waves just 10 centimeters high were detected around the same time in the Caribbean Sea, which is in an entirely different ocean basin. What was going on?

Researchers say there is only one reasonable explanation: The explosion's staggeringly powerful shock wave, screaming around the world close to the speed of sound, drove tsunamis of its own in both the Pacific and Atlantic oceans. It's the first time a volcanic shock wave has been seen creating its own tsunamis, says Greg Dusek, a physical oceanographer at the National Oceanic and Atmospheric Administration who documented the phenomenon using a combination of tide and pressure gauges around the world. But, "It's almost certainly happened in the past," says Mark Boslough, a physicist at the University of New Mexico, Albuquerque. The discovery suggests the shock waves generated by explosive eruptions in Earth's history, and by other violent cataclysms, like the airbursts of comets or asteroids colliding with the planet's atmosphere, may have also created transoceanic tsunamis, perhaps with considerably bigger waves.

The cocktail of chemical pollution that pervades the planet now threatens the stability of global ecosystems upon which humanity depends, scientists have said. The Guardian reports: Plastics are of particularly high concern, they said, along with 350,000 synthetic chemicals including pesticides, industrial compounds and antibiotics. Plastic pollution is now found from the summit of Mount Everest to the deepest oceans, and some toxic chemicals, such as PCBs, are long-lasting and widespread. The study concludes that chemical pollution has crossed a "planetary boundary", the point at which human-made changes to the Earth push it outside the stable environment of the last 10,000 years.

Determining whether chemical pollution has crossed a planetary boundary is complex because there is no pre-human baseline, unlike with the climate crisis and the pre-industrial level of CO2 in the atmosphere. There are also a huge number of chemical compounds registered for use -- about 350,000 -- and only a tiny fraction of these have been assessed for safety. So the research used a combination of measurements to assess the situation. These included the rate of production of chemicals, which is rising rapidly, and their release into the environment, which is happening much faster than the ability of authorities to track or investigate the impacts. The well-known negative effects of some chemicals, from the extraction of fossil fuels to produce them to their leaking into the environment, were also part of the assessment. The scientists acknowledged the data was limited in many areas, but said the weight of evidence pointed to a breach of the planetary boundary. [...] The researchers said stronger regulation was needed and in the future a fixed cap on chemical production and release, in the same way carbon targets aim to end greenhouse gas emissions. Their study was published in the journal Environmental Science & Technology. "The rise of the chemical burden in the environment is diffuse and insidious," said Prof Sir Ian Boyd at the University of St Andrews. "Even if the toxic effects of individual chemicals can be hard to detect, this does not mean that the aggregate effect is likely to be insignificant."

"Regulation is not designed to detect or understand these effects. We are relatively blind to what is going on as a result. In this situation, where we have a low level of scientific certainty about effects, there is a need for a much more precautionary approach to new chemicals and to the amount being emitted to the environment."

Veronique Greenwood writes via The New York Times: Your skin is home to a thousand kinds of bacteria, and the ways they contribute to healthy skin are still largely mysterious. This mystery may be getting even more complex: In a paper published Thursday in the journal Cell Host & Microbe, researchers studying the many varieties of Cutibacterium acnes bacteria on 16 human volunteers found that each pore was a world unto itself. Every pore contained just a single type of C. acnes. C. acnes is naturally occurring, and the most abundant bacteria on skin. Its link to acne, the skin disease, is not clear, said Tami Lieberman, a professor at M.I.T. and an author of the new paper. If biologists want to unpack the relationship between your face's inhabitants and its health, it will be an important step to understand whether varying strains of C. acnes have their own talents or niches, and how the strains are distributed across your skin.

Each person's skin had a unique combination of strains, but what surprised the researchers most was that each pore housed a single variety of C. acnes. The pores were different from their neighbors, too -- there was no clear pattern uniting the pores of the left cheek or forehead across the volunteers, for instance. What's more, judging from the sequencing data, the bacteria within each pore were essentially identical. "There's a huge amount of diversity over one square centimeter of your face," said Arolyn Conwill, a postdoctoral researcher who is the study's lead author. "But within a single one of your pores, there's a total lack of diversity."

What the scientists think is happening is that each pore contains descendants of a single individual. Pores are deep, narrow crannies with oil-secreting glands at the bottom, Dr. Lieberman said. If a C. acnes cell manages to get down there, it may proliferate until it fills the pore with copies of itself. This would also explain why strains that don't grow very quickly manage to avoid being outcompeted by speedier strains on the same person. They're not competing with each other; they're living side by side in their own walled gardens. Intriguingly, these gardens are not very old, the scientists think. They estimate that the founding cells in the pores they studied took up residence only about one year before. What happened to the bacteria that previously lived there? The researchers don't know -- perhaps they were destroyed by the immune system, fell prey to viruses or were unceremoniously yanked out by a nose strip, clearing the way for new founders.
