A new article summarizes research from the University of Oxford and NIHR Oxford Health Biomedical Research Centre. Slashdot reader AleRunner writes: Nearly one in five people who have had Covid-19 are diagnosed with a psychiatric disorder such as anxiety, depression or insomnia within three months of testing positive for the virus," Natalie Grover writes. Although "people with a pre-existing mental health diagnosis" are 65% more likely to get COVID, so it may be that this is partly explained by doctors diagnosing illness that would otherwise be missed, the article suggests that the rate is double the rate for influenza and unexpectedly high so other explanations are needed. From the article: Paul Harrison, a professor of psychiatry at the University of Oxford, said more research was needed to establish whether a diagnosis of a psychiatric disorder could be directly linked to getting coronavirus. General factors that influence physical health were not captured in the records analysed, such as socio-economic background, smoking, or use of drugs. There was also potential that the general stressful environment of the pandemic is playing a role, he noted. Research suggests that people from poorer socio-economic backgrounds are more likely to suffer mental ill-health. Poverty also increases exposure to coronavirus, owing to factors like crowded housing and unsafe working conditions. "Equally, it's not at all implausible that Covid-19 might have some direct effect on your brain and your mental health. But I think that, again, remains to be positively demonstrated," said Mr. Harrison... The calculations were made on the basis of roughly 70 million US health records, including more than 62,000 cases of Covid-19 that did not require a hospital stay or an emergency department visit.

Popular Mechanics writes: In a new study, researchers found the traditional psychoactive drug ayahuasca stimulates the growth of new brain cells in the hippocampi of research mice. The hippocampus is responsible for many memory functions, and the mice dosed with ayahuasca also performed better in a battery of memory tests. While ayahuasca, a hallucinogenic and often purgative tea brewed from leaves of a shrub that grows in South America, contains the psychoactive compound N, N-dimethyltryptamine (DMT), it also packs harmine and tetrahydoharmine, two compounds that form new neurons from stem cells in a petri dish, per IFL Science. "The study, published in Translational Psychiatry, a Nature Research journal, reports the results of four years of in vitro and in vivo experimentation on mice..." according to one medical news site. José Ángel Morales, a researcher in the UCM and CIBERNED Department of Cellular Biology, tells them "This capacity to modulate brain plasticity suggests that it has great therapeutic potential for a wide range of psychiatric and neurological disorders, including neurodegenerative diseases." In neurodegenerative diseases, it is the death of certain types of neurons that causes the symptoms of pathologies such as Alzheimer's and Parkinson's. Although humans have the capacity to generate new neuronal cells, this depends on several factors and is not always possible. "The challenge is to activate our dormant capacity to form neurons and thus replace the neurons that die as a result of the disease. This study shows that DMT is capable of activating neural stem cells and forming new neurons," concluded Morales.

Today's must-listen podcast: Radio Open Source. A review of the election with eight regular guests. Take-away: Dems need candidates that working class people connect with.

Programming columnist Mike Melanson assesses the news that Guido Van Rossum, the creator of the Python programming language, has come out of retirement to join Microsoft's developer division: The news brought a flurry of congratulations and feature requests, though a few of the suggested features indeed, already exist. Others still were met with informative responses that make the resulting threads worth a perusal, especially if you're looking for a quick "who's who" on Twitter for the world of programming languages. Microsoft's Miguel de Icaza pointed out that this addition adds to the company's now growing list of language designers and contributors: "The developer division at Microsoft now employs the language designers and contributors to Python, Java, JavaScript, Typescript, F# C#, C++. We just need some PHP, Rust and Swift magic to complete the picture." [Microsoft senior software engineer Kat Marchán added "We actually have some early ex-moz Rust people too!"] So, what can we expect from all of this? Is it a corporate takeover of open source, as some further down in the long list of replies always seem to suggest? Or is Microsoft planning the Frankenstein of all languages, with a little bit of this, a little bit of that? In all likelihood, you Python developers using Microsoft products probably have some good features to look forward to in the near future, and that's that, but there's always lingering fears...especially when it comes to Microsoft. As van Rossum suggests, stay tuned. After Slashdot's earlier story, long-time reader alexgieg posted his own theory: "Several months ago the Excel folk within Microsoft asked users whether they'd like to have Python as an alternative scripting language in Office. Support for that was overwhelming, but nothing more was said on the matter since then. I guess this is Microsoft's answer."

Slashdot reader Iwastheone shared this report from the Register: Google on Thursday was sued for allegedly stealing Android users' cellular data allowances though unapproved, undisclosed transmissions to the web giant's servers... The complaint contends that Google is using Android users' limited cellular data allowances without permission to transmit information about those individuals that's unrelated to their use of Google services... What concerns the plaintiffs is data sent to Google's servers that isn't the result of deliberate interaction with a mobile device — we're talking passive or background data transfers via cell network, here. "Google designed and implemented its Android operating system and apps to extract and transmit large volumes of information between Plaintiffs' cellular devices and Google using Plaintiffs' cellular data allowances," the complaint claims... Android users have to accept four agreements to participate in the Google ecosystem: Terms of Service; the Privacy Policy; the Managed Google Play Agreement; and the Google Play Terms of Service. None of these, the court filing contends, disclose that Google spends users' cellular data allowances for these background transfers. To support the allegations, the plaintiff's counsel tested a new Samsung Galaxy S7 phone running Android, with a signed-in Google Account and default setting, and found that when left idle, without a Wi-Fi connection, the phone "sent and received 8.88 MB/day of data, with 94 per cent of those communications occurring between Google and the device." The device, stationary, with all apps closed, transferred data to Google about 16 times an hour, or about 389 times in 24 hours. Assuming even half of that data is outgoing, Google would receive about 4.4MB per day or 130MB per month in this manner per device subject to the same test conditions... An iPhone with Apple's Safari browser open in the background transmits only about a tenth of that amount to Apple, according to the complaint... Vanderbilt University Professor Douglas C. Schmidt performed a similar study in 2018 — except that the Chrome browser was open — and found that Android devices made 900 passive transfers in 24 hours... The complaint charges that Google conducts these undisclosed data transfers for further its advertising business, sending "tokens" that identify users for targeted advertising and preload ads that generate revenue even if they're never displayed.

An anonymous reader quotes a report from IEEE Spectrum: While setting fire to an iron ingot is probably more trouble than it's worth, fine iron powder mixed with air is highly combustible. When you burn this mixture, you're oxidizing the iron. Whereas a carbon fuel oxidizes into CO2, an iron fuel oxidizes into Fe2O3, which is just rust. The nice thing about rust is that it's a solid which can be captured post-combustion. And that's the only byproduct of the entire business -- in goes the iron powder, and out comes energy in the form of heat and rust powder. Iron has an energy density of about 11.3 kWh/L, which is better than gasoline. Although its specific energy is a relatively poor 1.4 kWh/kg, meaning that for a given amount of energy, iron powder will take up a little bit less space than gasoline but it'll be almost ten times heavier. It might not be suitable for powering your car, in other words. It probably won't heat your house either. But it could be ideal for industry, which is where it's being tested right now. Researchers from TU Eindhoven have been developing iron powder as a practical fuel for the past several years, and last month they installed an iron powder heating system at a brewery in the Netherlands, which is turning all that stored up energy into beer. Since electricity can't efficiently produce the kind of heat required for many industrial applications (brewing included), iron powder is a viable zero-carbon option, with only rust left over. So what happens to all that rust? This is where things get clever, because the iron isn't just a fuel that's consumed -- it's energy storage that can be recharged. And to recharge it, you take all that Fe2O3, strip out the oxygen, and turn it back into Fe, ready to be burned again. It's not easy to do this, but much of the energy and work that it takes to pry those Os away from the Fes get returned to you when you burn the Fe the next time. The idea is that you can use the same iron over and over again, discharging it and recharging it just like you would a battery. To maintain the zero-carbon nature of the iron fuel, the recharging process has to be zero-carbon as well. There are a variety of different ways of using electricity to turn rust back into iron, and the TU/e researchers are exploring three different technologies based on hot hydrogen reduction (which turns iron oxide and hydrogen into iron and water). [...] Both production of the hydrogen and the heat necessary to run the furnace or the reactors require energy, of course, but it's grid energy that can come from renewable sources. [...] Philip de Goey, a professor of combustion technology at TU/e, told us that he hopes to be able to deploy 10 MW iron powder high-temperature heat systems for industry within the next four years, with 10 years to the first coal power plant conversion.

"The rising popularity of alternative social media app Parler is raising concerns over the spread of misinformation and potential for radicalizing users on a platform that's taken a hands-off approach to regulating content," reports The Hill's reporter on technology policy: The app has been boosted by conservatives, surging since Election Day, as Republicans amp up allegations of anti-conservative bias from social media giants like Twitter and Facebook that have clamped down on pro-Trump election misinformation. Experts warn that a total lack of content moderation could prove harmful beyond creating political echo chambers and further spreading conspiracy theories. "Anytime you take a laissez faire approach to moderation — you say, 'anything goes' right up until actual threats of real world violence — that creates a huge space for some really problematic things to happen," said Bret Schafer, a fellow focusing on disinformation at the Alliance for Securing Democracy.... For those who have abandoned Twitter and Facebook in favor of Parler, it could create a new dynamic on the mainstream social media platforms. "The idea that these people are leaving those platforms and no longer trying to red pill individuals to see their conspiracy theories on large platforms like Facebook and Twitter, I think that's a good thing," said Jason Blazakis, director of the Center on Terrorism, Extremism, and Counterterrorism at the Middlebury Institute. He added that the shift to Parler could mean fewer people on Facebook and Twitter are "exposed to these ideas," and "migrating to more obscure platforms" may ultimately result in a smaller audience for misinformation.... Unchecked content also risks exploitation of misinformation by foreign actors, much like it did on U.S. social media platforms in 2016, said Saif Shahin, an assistant professor at American University's School of Communications. But he said Parler's success underscores that misinformation in the U.S. is now fundamentally a domestic problem. "We have people in this country divided so sharply along partisan lines that they actively are seeking what we consider to be disinformation, but what they consider just one type of information," Shahin said. "It is a domestic problem, a social problem, within American society." Long-time Slashdot reader shilly also shared a thread on Twitter from entrepreneur/activist Dave Troy (currently a TedX organizer) raising questions about Parler's funding, and asserting that "a preliminary analysis of the first several thousand accounts on Parler shows that it is the usual Russia-aligned operatives that we in this space have tracked for years. This is a large-scale op aligned with Russian interests." Within hours Russia's state-controlled media outlet "Russia Today" had published an article calling Troy an "unhinged conspiracy theorist."

"Ubuntu developers have fixed a series of vulnerabilities that made it easy for standard users to gain coveted root privileges," reports Ars Technica: "This blog post is about an astonishingly straightforward way to escalate privileges on Ubuntu," Kevin Backhouse, a researcher at GitHub, wrote in a post published on Tuesday. "With a few simple commands in the terminal, and a few mouse clicks, a standard user can create an administrator account for themselves." The first series of commands triggered a denial-of-service bug in a daemon called accountsservice, which as its name suggests is used to manage user accounts on the computer... With the help of a few extra commands, Backhouse was able to set a timer that gave him just enough time to log out of the account before accountsservice crashed. When done correctly, Ubuntu would restart and open a window that allowed the user to create a new account that — you guessed it — had root privileges... The second bug involved in the hack resided in the GNOME display manager, which among other things manages user sessions and the login screen. The display manager, which is often abbreviated as gdm3, also triggers the initial setup of the OS when it detects no users currently exist. "How does gdm3 check how many users there are on the system?" Backhouse asked rhetorically. "You probably already guessed it: by asking accounts-daemon! So what happens if accounts-daemon is unresponsive....?" The vulnerabilities could be triggered only when someone had physical access to, and a valid account on, a vulnerable machine. It worked only on desktop versions of Ubuntu. "This bug is now tracked as CVE-2020-16125 and rated with a high severity score of 7.2 out of 10. It affects Ubuntu 20.10, Ubuntu 20.04, and Ubuntu 18.04..." reports Bleeping Computer.

We've been aware since long before the election that the Repubs could play games with the Electoral College, appointing a group of Electors in states Biden won with Republican legislatures, who do not vote according to the popular vote. This was contemplated in Florida in 2000 by its Republican legislature, but was made unnecessary by the Supreme Court decision.

Then I heard Trippi's theory, that McConnell et al are using Trump to support the Republican candidates in the Georgia runoff on January 5. I found it convincing, but the theory doesn't say what happens after that. What if the Electoral College (December 14, a couple of weeks before January 5) elects Biden? Hard to imagine Trump campaigning too enthusiastically for Loeffler and Perdue.

Then this Guardian article I read last night left me convinced that the Repubs should be considered seriously as trying to keep Trump in power through Electoral College shenanigans.

And finally this tweet from AP Washington bureau chief, Julie Pace, that says "GOP leaders in four critical states won by Biden say they won’t participate in a legally dubious scheme to flip electors to Trump. Their comments effectively shut down a half-baked plot some Republicans floated as a last chance to keep Trump in office."

It's still not clear exactly how and who will remove Trump from the White House if he doesn't go voluntarily on January 20.

Meanwhile it couldn't hurt to have peaceful candlelight vigils in the Republican state capitals: Madison, Lansing, Harrisburg, Atlanta, Phoenix.

Suppose one were to contemplate a new scripting language that was minimally different from JavaScript, was implemented by a pre-processor (ie it generated JavaScript code), that could handle any JavaScript code or data structure, but -- allowed you to implement asynchronous functions that were called synchronously, both in the built-in functions and developer-defined functions, without using special syntax such as promises or await/async to invoke them.
