An anonymous reader quotes a report from Motherboard: Scientists have witnessed brain patterns in dying patients that may correlate to commonly reported “near-death” experiences (NDEs) such as lucid visions, out-of-body sensations, a review of one’s own life, and other “dimensions of reality,” reports a new study. The results offer the first comprehensive evidence that patient recollections and brain waves point to universal elements of NDEs. During an expansive multi-year study led by Sam Parnia, an intensive care doctor and an associate professor in the department of medicine at NYU Langone Health, researchers observed 567 patients in 25 hospitals around the world as they underwent cardiopulmonary resuscitation (CPR) after suffering cardiac arrest, most of which were fatal.

Electroencephalogram (EEG) brain signals captured from dozens of the patients revealed that episodes of heightened consciousness occurred up to an hour after cardiac arrest. Though most of the patients in the study were sadly not resuscitated by CPR, 53 patients were brought back to life. Of the survivors, 11 patients reported a sense of awareness during CPR and six reported a near-death experience. Parnia and his colleagues suggest that the transition from life to death can trigger a state of disinhibition in the brain that “appears to facilitate lucid understanding of new dimensions of reality — including people’s deeper consciousness — all memories, thoughts, intentions and actions towards others from a moral and ethical perspective,” a finding with profound implications for CPR research, end-of-life care, and consciousness, among other fields, according to a new study published in Resuscitation. […]

“One of the things that was unique about this project is that this was the first time ever where scientists had put together a method to examine for signs of lucidity and consciousness in people as they’re being revived by looking for brain markers, or brain signatures of consciousness, using an EEG device as well as a brain oxygen monitor,” Parnia explained. “Most doctors are taught and believe that the brain dies after about five or 10 minutes of oxygen deprivation,” Parnia said. “One of the key points that comes out of this study is that that is actually not true. Although the brain flatlines after the heart stops, and that happens within seconds, it doesn’t mean that it’s permanently damaged and [has] died. It’s just hibernating. What we were able to show is that actually, the brain can respond and restore function again, even after an hour later, which opens up a whole window of opportunity for doctors to start new treatments.” Indeed, the study reports that “near-normal/physiological EEG activity (delta, theta, alpha, beta rhythms) consistent with consciousness and a possible resumption of a network-level of cognitive and neuronal activity emerged up to 35-60 minutes into CPR. This is the first report of biomarkers of consciousness during CA/CPR.”

The Associated Press reports: The National Security Agency is starting an artificial intelligence security center — a crucial mission as AI capabilities are increasingly acquired, developed and integrated into U.S. defense and intelligence systems, the agency’s outgoing director announced Thursday. Army Gen. Paul Nakasone said the center would be incorporated into the NSA’s Cybersecurity Collaboration Center, where it works with private industry and international partners to harden the U.S. defense-industrial base against threats from adversaries led by China and Russia.

Nakasone was asked about using AI to automate the analysis of threat vectors and red-flag alerts — and he reminded the audience that U.S. intelligence and defense agencies already use AI. “AI helps us, But our decisions are made by humans. And that’s an important distinction,” Nakasone said. “We do see assistance from artificial intelligence. But at the end of the day, decisions will be made by humans and humans in the loop.”

Nakasone said it would become “NSA’s focal point for leveraging foreign intelligence insights, contributing to the development of best practices guidelines, principles, evaluation, methodology and risk frameworks” for both AI security and the goal of promoting the secure development and adoption of AI within “our national security systems and our defense industrial base.” He said it would work closely with U.S. industry, national labs, academia and the Department of Defense as well as international partners.

Mike Wall writes via Space.com: OSIRIS-REx’s asteroid-sample canister just creaked open for the first time in more than seven years. Scientists at NASA’s Johnson Space Center (JSC) in Houston lifted the canister’s outer lid on Tuesday (Sept. 26), two days after OSIRIS-REx’s return capsule landed in the desert of northern Utah. “Scientists gasped as the lid was lifted,” NASA’s Astromaterials Research and Exploration Science (ARES) division, which is based at JSC, wrote Tuesday in a post on X (formerly Twitter). The operation revealed “dark powder and sand-sized particles on the inside of the lid and base,” they added.

That powder once resided on the surface of an asteroid named Bennu, the focus of the OSIRIS-REx mission. OSIRIS-REx launched toward the 1,650-foot-wide (500 meters) Bennu in September 2016, arrived in December 2018 and snagged a hefty sample from the space rock in October 2020 using its Touch-and-Go Sample Acquisition Mechanism, or TAGSAM. The asteroid material landed in Utah inside OSIRIS-REx’s return capsule on Sunday (Sept. 24), then made its way to Houston by plane on Monday (Sept. 25). It will be stored and curated at JSC, where the team will oversee its distribution to scientists around the world.

Researchers will study the sample for decades to come, seeking insights about the the solar system’s formation and early evolution, as well as the role that carbon-rich asteroids like Bennu may have played in seeding Earth with the building blocks of life. But that work isn’t ready to begin; the ARES team hasn’t even accessed the main asteroid sample yet. Doing so requires disassembly of the TAGSAM apparatus, an intricate operation that will take considerable time.

An anonymous reader quotes a report from the BBC: What I felt was fear,” says Claudia Duarte Agostinho as she remembers the extreme heatwave and fires that ripped through Portugal in 2017 and killed more than 100 people. “The wildfires made me really anxious about what sort of future I would have.” Claudia, 24, her brother Martim, 20, and her sister Mariana, 11, are among six young Portuguese people who have filed a lawsuit against 32 governments, including all EU member states, the UK, Norway, Russia, Switzerland and Turkey. They accuse the countries of insufficient action over climate change and failing to reduce their greenhouse gas emissions enough to hit the Paris Agreement target of limiting global warming to 1.5C. The case is the first of its kind to be filed at the European Court of Human Rights (ECHR) in Strasbourg. If it is successful, it could have legally-binding consequences for the governments involved. The first hearing in the case is being held on Wednesday.

Aged from 11 to 24, the six claimants argue that the forest fires that have occurred in Portugal each year since 2017 are a direct result of global warming. They claim that their fundamental human rights — including the right to life, privacy, family life and to be free from discrimination — are being violated due to governments’ reluctance to fight climate change. They say they have already been experiencing significant impacts, especially because of extreme temperatures in Portugal forcing them to spend time indoors and restricting their ability to sleep, concentrate or exercise. Some also suffer from eco-anxiety, allergies and respiratory conditions including asthma. None of the young applicants is seeking financial compensation.

Lawyers representing the six young claimants are expected to argue in court that the 32 governments’ current policies are putting the world on course for 3C of global warming by the end of the century. […] In separate and joint responses to the case, the governments argue that the claimants have not sufficiently established that they have suffered as a direct consequence of climate change or the Portuguese wildfires. They claim there is no evidence to show climate change poses an immediate risk to human life or health, and also argue that climate policy is beyond the scope of the European Court of Human Rights jurisdiction. “These six young people from Portugal, who are ordinary individuals concerned about their future, will be facing 32 legal teams, hundreds of lawyers representing governments whose inaction is already harming them,” says Gearoid O Cuinn, director of Global Legal Action Network (GLAN).

“So this is a real David vs Goliath case that is seeking a structural change to put us on a much better track in terms of our future.”

Liam Proven writes via The Register: Steam OS is the Arch-based distro for a handheld Linux games console, and Valve is aggressively pushing Linux’s usability and Windows interoperability for the device. Two unusual companies, Valve Software and Igalia, are working together to improve the Linux-based OS of the Steam Deck handheld games console. The device runs a Linux distro called Steam OS 3.0, but this is a totally different distro from the original Steam OS it announced a decade ago. Steam OS 1 and 2 were based on Debian, but Steam OS 3 is based on Arch Linux, as Igalia developer Alberto Garcia described in a talk entitled How SteamOS is contributing to the Linux ecosystem.

He explained that although Steam OS is built from some fairly standard components — the normal filesystem hierarchy, GNU user space, systemd and dbus — Steam OS has quite a few unique features. It has two distinct user interfaces: by default, it starts with the Steam games launcher, but users can also choose an option called Switch to Desktop, which results in a regular KDE Plasma desktop, with the ability to install anything: a web browser, normal Linux tools, and non-Steam games.

Obviously, though, Steam OS’s raison d’etre is to run Steam games, and most of those are Windows games which will never get native Linux versions. Valve’s solution is Proton, an open-source tool to run Windows games on Linux. It’s formed from a collection of different FOSS packages, notably: [Wine, DXVK, VKD3D-Proton, and GStreamer]. The result is a remarkable degree of compatibility for some of the most demanding Windows apps around […]. You can view Garcia’s 49-page presentation here (PDF).
