  • Researchers Pinpoint Reason Infants Die From SIDS

    This is a great breakthrough for such a tragic disease, and one which has led to terrible miscarriages of justice.

    SIDS refers to the unexplained deaths of infants under a year old, and it usually occurs while the child is sleeping. According to Mayo Clinic, many in the medical community suspected this phenomenon could be caused by a defect in the part of the brain that controls arousal from sleep and breathing. The theory was that if the infant stopped breathing during sleep, the defect would keep the child from startling or waking up.  The Sydney researchers were able to confirm this theory by analyzing dried blood samples taken from newborns who died from SIDS and other unknown causes. Each SIDS sample was then compared with blood taken from healthy babies. They found the activity of the enzyme butyrylcholinesterase (BChE) was significantly lower in babies who died of SIDS compared to living infants and other non-SIDS infant deaths. BChE plays a major role in the brain’s arousal pathway, explaining why SIDS typically occurs during sleep.  Previously, parents were told SIDS could be prevented if they took proper precautions: laying babies on their backs, not letting them overheat and keeping all toys and blankets out of the crib were a few of the most important preventative steps. While safe sleep practices are still important for protecting infants, many children whose parents took every precaution still died from SIDS. These parents were left with immense guilt, wondering if they could have prevented their baby’s death. Dr. Carmel Harrington, the lead researcher for the study, was one of these parents. Her son unexpectedly and suddenly died as an infant 29 years ago. In an interview with the Australian Broadcasting Corporation (ABC), Harrington explained what she was told about the cause of her child’s death.  “Nobody could tell me. They just said it’s a tragedy. But it was a tragedy that didn’t sit well with my scientific brain.”  Since then, she’s worked to find the cause of SIDS, both for herself and for the medical community as a whole. She went on to explain why this discovery is so important for parents whose babies suffered from SIDS.  “These families can now live with the knowledge that this was not their fault,” she said.

  • Chat Control

    “The End of the Privacy of Digital Correspondence”:

    The EU wants to oblige providers to search all private chats, messages, and emails automatically for suspicious content – generally and indiscriminately. The stated aim: To prosecute child pornography. The result: Mass surveillance by means of fully automated real-time messaging and chat control and the end of secrecy of digital correspondence. Other consequences of the proposal are ineffective network blocking, screening of person cloud storage including private photos, mandatory age verification leading to the end of anonymous communication, censorship in Appstores and the paternalism and exclusion of minors in the digital world.

  • Thought-terminating cliché

    A thought-terminating cliché (also known as a semantic stop-sign, a thought-stopper, bumper sticker logic, or cliché thinking) is a form of loaded language, often passing as folk wisdom, intended to end an argument and quell cognitive dissonance. Its function is to stop an argument from proceeding further, ending the debate with a cliché rather than a point.
    Examples: “it is what it is”, “it’s in God’s hands”, “YOLO”, or the Irish favourite: “we all partied”

  • “Hypercoagulation” as a potential long COVID sign

    Interesting Twitter thread discussing a potential treatment for long COVID — no interest in providing even the relevant _tests_ in the UK, so a British kid was brought to Germany to receive the treatment, and is now responding well. Here’s details on the specific biosigns:

    Her fluorescent microscopy showed very hyperactivated sticky platelets. Mine are on the right for comparison. She also had microclots and evidence of endothelial damage (but latter not severe). I believe she was the first UK child under 12 to have these tests done. The platelets and microclots show that her blood is ‘hypercoaguable’ – too sticky. These may be blocking up the very small blood vessels that allow oxygen into muscles and nerves, which could explain some of her symptoms.

  • “The first Starlink war”

    Very interesting thread from Trent Telenko on how a Ukrainian GIS app, combined with Starlink internet access, has created 21st century artillery warfare and outflanked the Russia military:

    Ukraine’s ‘GIS Art for Artillery’ app combined with Starlink actually gives the Ukrainian military measurably better than US Military standard artillery command and control. The Ukraine War is the first Starlink War & the side with Starlink is beating the side without.
    This is pretty nuts. On the other hand, though, Starlink’s operational security is now critically important, and doubtless being heavily targeted by Russian hackers, and Ukraine’s tactics are reliant on the vagaries of Elon Musk… Source twitter thread:

  • Trino | Project Tardigrade delivers ETL at Trino speeds to early users

    This looks fantastic — Trino (nee Presto) adds some significant improvements for long-running and heavyweight query support.

    When your long-running queries experience a failure, they don’t have to start from scratch. When queries require more memory than currently available in the cluster they are still able to succeed. When multiple queries are submitted concurrently they are able to share resources in a fair way, and make steady progress.

  • metabolically-led post-exertional symptoms in Long COVID

    Interesting thread from a Mount Sinai-based lab discussing the side effects of possible mitochondrial dysfunction and oxidative stress:

    Our cells use a very specific fuel source called ATP that is produced in a part of the cell called the mitochondria. Unfortunately, ATP also fuels the cellular activities of viruses. As such, when a virus enters our cells it quickly hijacks our mitochondria to fuel viral replication and other viral activities. In other words when you are infected by a virus like #COVID19, you are infected by a little energy thief: taking your hard-earned ATP and using it for its own purposes. Not only does this mean that the virus is proliferating on stolen energy (rude!) but it also means that your cells must perform their regular functions with far less energy. So this is where things get cyclical: we have hijacked mitochondria resulting in inefficient, “stressed“ cells. Our cells are producing energy “for two” now, but barely managing to function, leading to the overproduction of reactive oxygen species (ROS), which we can think of as the “exhaust fumes” of our mitochondria. ROS are bad characters – systemically, they can trigger inflammation and hypocapnia. Unfortunately, once the body is experiencing oxidative stress, the mere act of producing more energy starts to damage the mitochondria.

  • “Living with COVID” has been a lie

    This is a fantastic thread from Luca Ferretti:

    “Living with COVID” has been a lie. Not because it isn’t possible, or because it isn’t the right goal. But in practice it has clearly morphed into “let’s stop talking about COVID, and the problem will disappear by itself”. A dangerous and irresponsible bet. Most of the political & health authorities have implicitly chosen to rely mainly on vaccination to control COVID. A reasonable choice… if only the vaccination campaign would have aimed at protecting the entire population with sterilising vaccines adapted to the new variants. Instead, despite hundreds of vaccines in the pipeline, there are no next-generation or sterilising vaccines on the horizon… little large-scale clinical trials (apart from Israel)… and few updated vaccines against variants (Moderna’s Omicron-Delta booster and little else). Of course, protection for children has been repeatedly delayed (English kids between 5-11 were vaccinated only last month) and kids under 5 are still unprotected worldwide, with the laudable exception of Cuba. Everybody’s waiting for the US FDA, whose intentions are unclear. It is truly depressing to see so little and slow concrete progress on what is meant to be “the ultimate weapon” against SARSCoV2. It seems to suggest that we don’t really rely so much on it, and that we’re satisfied with postponing the problems until the next not-so-mild variant. Simple precautionary public hygiene measures – face masks and ventilation – are mostly ignored. Testing and surveillance, downsized or limited. And the growing stress on the healthcare system is being swept under the carpet, even as we risk paying the price for it for years. This is not the product of any large conspiracy. It is simply the result of a combination of neglect, inertia, bureaucracy, selfishness, careerism, lack of long-term perspective and so on, among some (though not all!) politicians, doctors, academics, bureaucrats and others…

  • Bringing emulation into the 21st century

    Well executed satire:

    An 8080 microprocessor utilising a modern, containerised, microservices-based architecture running on Kubernetes with frontends for a CP/M test harness and a full implementation of the original Space Invaders arcade machine. The full project can be found as a github organisation which contains ~60 individual repositories each implementing an individual microservice or providing the infrastructure.
    Needless to say this monster runs at approximately 1KHz, instead of the required 2MHz. A good demo of how some deliberately obtuse and inappropriate architectural decisions can really make a mess of things.

  • GitHub has wiped out open source history by “suspending” Russian users

    This sounds like a pretty crappy way to go about things:

    It is unclear to me what GitHub’s intended result was with these account suspensions, but it appears to be incredibly destructive for any open source project that has interacted with a now-suspended account. On a service like Twitter, you can visit the placeholder profile of a suspended account and see a message communicating that the account is suspended, and other users’ @mentions of the account still link to the suspended account’s profile. On GitHub, that’s not how it works at all. Apparently, “suspending an account” on GitHub actually means deleting all activity for a user — which results in (1) every pull request from the suspended account being deleted, (2) every issue opened by the suspended account being deleted, (3) every comment or discussion from the suspended account being deleted. In effect, the user’s entire activity and history is evaporated. All of this valuable data is lost. The only thing left intact is the raw Git commit history. It’s as if the user never existed.

  • CVE-2022-21449: Psychic Signatures in Java

    Argh, this is a bad one:

    Recent releases of Java were vulnerable to a similar kind of trick, in the implementation of widely-used ECDSA signatures. If you are running one of the vulnerable versions then an attacker can easily forge some types of SSL certificates and handshakes (allowing interception and modification of communications), signed JWTs, SAML assertions or OIDC id tokens, and even WebAuthn authentication messages. All using the digital equivalent of a blank piece of paper. It’s hard to overstate the severity of this bug. If you are using ECDSA signatures for any of these security mechanisms, then an attacker can trivially and completely bypass them if your server is running any Java 15, 16, 17, or 18 version before the April 2022 Critical Patch Update (CPU). For context, almost all WebAuthn/FIDO devices in the real world (including Yubikeys*) use ECDSA signatures and many OIDC providers use ECDSA-signed JWTs.

  • Data from French long COVID cohort

    This is a decent step forward in long COVID research. 968 self-selected long covid sufferers reporting their symptom progression over a year: “Proud to present our results on the course of Long Covid symptoms over time, using the @PatientsComPaRe cohort and recently published in @NatureComms. after 1 year 85% of patients still reported some symptoms; there were specific trajectories depending on symptoms (pane A). For example, 40% reported cough 60 days after symptom onset vs. 20% at 12 months after onset; 50% of patients report a considerable impact on their professional lives; Long Covid is a relapsing remitting disease. It seems that, over time, relapses tend to be less frequent; Future research will look at patient trajectories (understanding those who get better vs others) and looking at biomarkers of long COVID”.

  • “FAANG promo committees are killing Kubernetes”

    This makes a lot of sense. Letting “working for a big software company” be the only way to effectively get paid to collaborate on open source wasn’t a great idea.

    Promo committees have, for years now, been consistently undervaluing the work of full-time Kubernetes contributors. Or really of open source work more broadly. Attributable revenue has been taking over as one of the most important factors at most companies. And Kubernetes has very little of that. It’s happened gradually, and I don’t think this was ever an intended outcome but it’s a thing and we have to live with it. It’s too indirect, fixing a bug in kube-apiserver might retain a GCP customer or avoid a costly Apple services outage, but can you put a dollar value on that? How much is CI stability worth? Or community happiness? And then add on top of it, the time cost. “FOSS maintainers are overloaded” should not be news to anyone, but now add 20/hours a week of campaigning to other high-level folks to “build buzz” for your work and let me know how that goes.

  • The three big myths about Omicron

  • We can’t rely on boosters to get through each new wave of Covid

    This is very worrying, given our government’s current “just boosters” strategy for dealing with COVID-19:

    We are living in a precarious truce imposed through frequent mRNA boosters to keep the viral caseload “manageable”. But there are signs this isn’t sustainable, and that a strategy simply consisting of boosters in perpetuity may not be fit for purpose. Recent case surges in Hong Kong, Denmark and Scotland emphasise the fragility of that balance. And new evidence from the past two years suggests that encounters with different variants of Covid or different vaccine types can alter the effectiveness of later jabs in surprising ways – an effect called immune imprinting. This raises the possibility that booster performance could be even less predictable and effective in the future. Sars-CoV-2 began as a single variant, which we term the Wuhan strain. But we now inhabit a world where no two people share precisely the same exposure history: we have never been infected, or were asymptomatically, mildly or severely infected during any or a combination of the Wuhan to Alpha, Delta, Omicron or BA.2 waves, and we’ve all had somewhere from zero to four doses of diverse vaccines. The combination of these exposures gives each of us a unique immune memory repertoire.
    The author is Danny Altmann, a professor of immunology at Imperial College London.

  • Dual use of artificial-intelligence-powered drug discovery | Nature Machine Intelligence

    Well, this is terrifying:

    In less than 6 hours after starting on our in-house server, our [machine learning] model generated 40,000 molecules that scored within our desired threshold. In the process, the AI designed not only VX, but also many other known chemical warfare agents that we identified through visual confirmation with structures in public chemistry databases. Many new molecules were also designed that looked equally plausible. These new molecules were predicted to be more toxic, based on the predicted LD50 values, than publicly known chemical warfare agents (Fig. 1). This was unexpected because the datasets we used for training the AI did not include these nerve agents. The virtual molecules even occupied a region of molecular property space that was entirely separate from the many thousands of molecules in the organism-specific LD50 model, which comprises mainly pesticides, environmental toxins and drugs (Fig. 1). By inverting the use of our machine learning models, we had transformed our innocuous generative model from a helpful tool of medicine to a generator of likely deadly molecules.

  • New-onset IgG autoantibodies in hospitalized patients with COVID-19

    This is not great — this article in Nature from Sep 2021 details “autoimmune features and autoantibody production” associated with COVID-19 infection.

    COVID-19 is associated with a wide range of clinical manifestations, including autoimmune features and autoantibody production. Here we develop three protein arrays to measure IgG autoantibodies associated with connective tissue diseases, anti-cytokine antibodies, and anti-viral antibody responses in serum from 147 hospitalized COVID-19 patients. Autoantibodies are identified in approximately 50% of patients but in less than 15% of healthy controls. When present, autoantibodies largely target autoantigens associated with rare disorders such as myositis, systemic sclerosis and overlap syndromes. A subset of autoantibodies targeting traditional autoantigens or cytokines develop de novo following SARS-CoV-2 infection. [….] We conclude that SARS-CoV-2 causes development of new-onset IgG autoantibodies in a significant proportion of hospitalized COVID-19 patients and are positively correlated with immune responses to SARS-CoV-2 proteins.

  • study of “Long COVID” symptoms in the Danish population

    These numbers are frankly massive:

    Six to twelve months after the test date, the risks of 18 out of 21 physical symptoms were elevated among test-positives and one third (29.6%) of the test-positives experienced at least one physical post-acute symptom. [jm: “test-positives” are “individuals aged 15-years or older, consisting of RT-PCR confirmed SARS-CoV-2 cases between September 2020 – April 2021”] The largest risk differences were observed for dysosmia (RD = 10.92%, 95%CI 10.68-11.21%), dysgeusia (RD=8.68%, 95%CI 8.43-8.93%), fatigue/exhaustion (RD=8.43%, 95%CI 8.14-8.74%), dyspnea (RD=4.87%, 95%CI 4.65-5.09%) and reduced strength in arms/legs (RD=4.68%, 95%CI 4.45-4.89%). More than half (53.1%) of test-positives reported at least one of the following conditions: concentration difficulties (RD=28.34%, 95%CI 27.34-28.78%), memory issues (RD=27.25%, 95%CI 26.80-27.71%), sleep problems (RD=17.27%, 95%CI 16.81-17.73%), mental (RD=32.58%, 95%CI 32.11-33.09%) or physical exhaustion (RD=40.45%, 95%CI 33.99-40.97%), compared to 11.5% of test-negatives. New diagnoses of anxiety (RD=1.15%, 95%CI 0.95-1.34%) or depression (RD=1.00%, 95%CI 0.81-1.19%) were also more common among test-positives. Interpretation: At the population-level, where the majority of test-positives (96.0%) were not hospitalized during acute infection, a considerable proportion experience post-acute symptoms and sequelae 6-12 months after infection.

  • New – Customer Carbon Footprint Tool | AWS News Blog

    ‘Starting today customers can calculate the environmental impact of their AWS workloads with the new customer carbon footprint tool. This new tool uses easy-to-understand data visualizations to provide customers with their historical carbon emissions, evaluate emission trends as their use of AWS evolves, approximate the estimated carbon emissions they have avoided by using AWS instead of an on-premises data center, and review forecasted emissions based on current use. The forecasted emissions are based on current usage, and show how a customer’s carbon footprint will change as Amazon stays on path to powering its operations with 100% renewable energy by 2025, five years ahead of its original target of 2030, and drives toward net-zero carbon by 2040 as part of The Climate Pledge. The customer carbon footprint tool is visible today through the AWS Billing console and helps to support customers on their sustainability journey. When signed into the AWS Billing console, customers can view their carbon emissions data by geographical location and by AWS services, such as Amazon Elastic Compute Cloud (EC2) and Amazon Simple Storage Service (S3). They can also measure changes in their carbon footprint over time, as they deploy new resources in the cloud. The new tool uses data that meets the Greenhouse Gas Protocol, which is the international standard for greenhouse gas reporting.’ Covers Scope 1 and Scope 2 emissions.

  • a short story about pandemic misinformation & biased reporting

    Well-illustrated case study from 2021 in how misinformation evolves in the mainstream press. First, an Irish Times journalist concocted a thesis (“Given that only 1 in 1,000 cases of COVID-19 come from an outdoor setting, is the government too prohibitive on people meeting outdoors?”), and got a weakly confirmatory response from the HPSC (who should have known better). Through poor reporting by other newspapers around the world, this quickly became a “fact” reported by an Irish “study” — despite being nothing of the sort — and published in the New York Times and NPR. Eventually it became a research reference in several academic papers and the BMJ. Naturally, warnings from experts, and the Minister for Health, about its inaccuracy, were ignored. What a mess…
