🤖 AI Summary

Jupiterの雷は地球よりも100~1万倍のエネルギーを持つという研究結果が明らかになりました。NASAの Juno衛星に搭載された装置を使用して、研究人员发现,木星的闪电的能量是地球上的一百万到一亿倍。一个地球上的闪电释放大约1亿焦耳的能量,而最强烈的木星闪电则可达到10万亿焦耳,相当于2400吨TNT爆炸的能量,相当于广岛原子弹威力的六分之一。

Junoが観測した4つの嵐のうち、平均で3秒に1回雷を打つことが確認され、これらの嵐は直径3000キロメートル以上で、ニューヨークからデンバーまでを越える大きさです。研究者たちはハブスペーステlescopeとジュノ衛星の写真を使用して嵐を精密に追跡し、その放射計測器が個々の雷を特定することができました。

カーディフ大学の雷電気学者で本研究には関与していないダニエル・ミッチャード氏は、「ただ巨大なガス球だ。非常にエネルギーのある雷があるのは理に適っている」と述べた上で、「しかし、そのような疑念が確認される事は興奮する。」と語った。雷は複雑な化学反応を生み出す役割を果たしており、原始的な生命の構築にも重要であるからだ。
How powerful is Jupiter's lightning? Thick clouds cover the view, notes Science magazine. But using an instrument on NASA's Juno spacecraft (orbiting Jupiter for the past decade), researchers determined Jupiter's lightning bolts are 100 to 10,000 times more energetic than earth's: A single bolt of lightning on Earth releases about 1 billion joules of energy. That means the most extreme bolts of jovian lightning carry 10 trillion joules of energy, equivalent to 2400 tons of TNT, or one-sixth the power of the atomic bomb dropped on Hiroshima, Japan. Based on the rates of flashes seen by Juno, storms on this tempestuous world can unleash the force of multiple nuclear weapons every minute... The four storms Juno studied were monstrous, says Michael Wong, a planetary scientist at the University of California, Berkeley and one of the study's authors. There were three flashes per second on average, often emerging from the hearts of storms that are 3000 kilometers across, longer than the distance from New York City to Denver. The researchers used the Hubble Space Telescope (and photographs from Juno's camera) to track Jupiter's storms with such precision that their radiometer could then pick out individual lightning flashes, according to the article. "It's just a massive ball of gas. It makes sense that there's very energetic lightning happening," says Daniel Mitchard, a lightning physicist at Cardiff University who wasn't involved with the new study. But confirming such suspicions "is exciting," he says, because lightning plays an important role in forging complex chemistry — including the sort that primordial life is built on.

What Made Bell Labs So Successful?

🤖 AI Summary

贝尔实验室为何如此成功? jon gertner 在《华尔街日报》的文章中探讨了这个问题。贝尔实验室在现代科技的多个领域奠定了基础,包括晶体管、通信卫星以及Unix和C编程语言。

其成功的关键在于以下几个方面:

1. **丰富的技术问题环境**:贝尔实验室的任务是设计、扩展和完善混乱的通信网络。
2. **资金支持**:作为世界上最大的公司AT&T的一部分,贝尔实验室获得了巨额预算,可以进行持续的研究开发。
3. **垄断带来的长期思考优势**:由于没有竞争压力,工程师们可以在几十年内研究复杂的技术问题。
4. **创新的管理**:梅尔文·凯利领导下的贝尔实验室重视跨学科团队和不同背景研究人员的合作。这种结构促进了创意和观点之间的摩擦。

尽管贝尔实验室在AT&T垄断被打破后逐渐衰落,但它仍为全球通信和电子技术的发展奠定了基础,并获得了约3万项专利。如今,它已成为芬兰诺基亚的一部分。文章指出,贝尔实验室的成功在于其独特的组织结构,即连接到一个庞大而盈利的垄断公司,并能将理论研究转化为实际产品。
Bell Labs "created many of the foundational innovations of the modern age," writes Jon Gertner, author of The Idea Factory: Bell Labs and the Great Age of American Innovation — from transistors and telecommunications satellites to Unix and the C programming language. But what was the secret to its success? he asks in a new article for the Wall Street Journal. Start with its lucky arrival in a "problem-rich" environment, suggests Arno Penzias, winner of one of Bell Labs' 11 Nobel Prizes: It was Bell Labs' responsibility, in other words, to create technologies for designing, expanding and improving an unruly communications network of cables and microwave links and glass fibers. The Labs also had to figure out ways to create underwater conduits, as well as switching centers that could manage the growing number of customers and escalating amounts of data.... Money mattered, too. Being connected to AT&T, the largest company in the world, was an advantage. The Labs' budget was enormous, and accounting conventions allowed its parent company to make huge and continuing investments in R & D. The generous funding, moreover, allowed scientists and engineers to buy and build expensive equipment — for instance, anechoic chambers to create the world's quietest rooms... The most fortunate part of Bell Labs' situation, however, was that in being attached to a monopoly it could partake in long-term thinking... Without competition nipping at its heels, Bell Labs engineers had the luxury of working out difficult ideas over decades. The first conceptualization of a cellular phone network, for instance, came out of the Labs in the late 1940s; it wasn't until the late 1970s that technicians began testing one in Chicago to gauge its potential. The challenge of deploying these technologies was immense. (The regulatory hurdles were formidable, too....) The article also credits the visionary management of Mervin Kelly — who fortunately also "had access to funding in a decade when most executives and universities didn't" to hire the brightest people. (By the early 1980s Bell Labs employed about 25,000 researchers, technicians and support staff, with an annual budget of $2 billion — roughly $7 billion in today's dollars.) "The Labs' involvement in World War II suggested to Kelly that an exciting postwar era of electronics was approaching, but that the technical problems would be so complex that they required a mix of expertise — not just physicists, but material scientists, chemists, electrical engineers, circuitry experts and the like." At Bell Labs, Kelly would sometimes handpick teams and create such a mix, as was the case for the transistor invention in the late 1940s. He came to see innovation arising not from like-minded or similarly trained people conversing with each other, but from a friction of ideas and approaches. It meant hiring researchers who had different personalities and favored a range of experimental angles. It also meant personally designing a campus in Murray Hill where departments were spread apart, so that scientists and engineers would be forced to walk, mingle and engage in serendipitous conversations and debate ideas. Meanwhile, under Kelly, the Labs focused on hiring people who were deeply curious, not just smart. Kelly saw it as his professional duty to do far more than what was expected, with his laboratory and vast resources, to create new technologies... The breakup of AT&T's monopoly, which led to a steady shrinking of Bell Labs' staff, budget and remit, shows us that no matter how forward looking your employees and managers may be, they will not necessarily see the future coming. It likewise suggests that technological progress is too unpredictable for one organization, no matter how powerful or smart, to control. Famously, Bell Labs managers didn't see value in the Arpanet, which eventually led to today's internet. And yet, for at least five decades, Bell Labs created a blueprint for the global development of communications and electronics. In understanding why it did so, I tend to think its ultimate secret may be hiding in plain sight. The secret has to do with Bell Labs' structure — not only being connected to a fabulously profitable monopoly, but being connected to a company that could move theoretical and applied research into a huge manufacturing division that made telecom equipment (at Western Electric) and ultimately into a dynamic operating system (the AT&T network)... Scientists and engineers at the Labs understood their ideas would be implemented, if they passed muster, into the huge system its parent company was running. Bell Labs racked up about 30,000 patents, according to the article, and celebrated its 100th anniversary last April. It is now part of Finland-based Nokia.

Disney Ends $1B OpenAI Investment After Sora's Surprise Closure. What's Next?

著者: EditorDavid
2026年3月29日 16:34

🤖 AI Summary

Disneyは、オープンAIのアビトゥアル生成ツール「ソラ」に関するプロジェクトで、わずか6日後にソラが急にサービスを終了したことに驚かされました。この決定はDisneyのチームにとっては予想外であり、「大きな手品」という形容です。14週前にDisneyは10億ドル規模の投資と3年間のライセンス契約を発表していましたが、その契約は成立せず、金銭移動もありませんでした。

ディズニーは公式に、AI技術を使ってファンに届ける新たな方法を見つけ出し、IPやクリエーターの権利を尊重しながら新しいテクノロジーを適応していくことを示唆しています。しかし、ソラとの契約が消えれば、 belovedなキャラクターたちがAI技術から遠ざかる可能性があります。

一方で、ディズニーは他の方法でもAIと提携し続ける可能性があります。 Deadlineは、この契約の終了は「人間の創造性を掠奪する不正なAIモデルとの取り決め」の模範ケースだったとしています。それは人気芸能人たちが支援している「Human Artistry Campaign」と「Creators Coalition on AI」にも受け入れられていた可能性があります。

しかし、OpenAIがソラを終了したことは、「アーティストと技術者を連携させるべきだ」という課題を浮き彫りにしています。これはハリウッドにとって大きなリスクを示唆しています。
Just six days ago — and 30 minutes after a Disney-OpenAI meeting about a project with Sora — Disney's team was "blindsided" with the news Sora was being discontinued, a person familiar with the matter told Reuters, describing OpenAI's move as "a big rug-pull." Even some Sora employees were surprised by the cancellation. It was just 14 weeks ago Disney announced a $1 billion investment in OpenAI's AI-powered video generation tool — plus a three-year licensing deal. But that deal "never closed," Reuters adds, citing two other people familiar with the matter, "and no money changed hands." (Although the two sides are still "discussing if there is another way they can partner or invest with one another, one of the people familiar with the matter said.") But Variety wonders if the end of the Sora deal is "a blessing in disguise" for Disney: Before Disney's officially sanctioned AI-generated versions of Mickey Mouse, Darth Vader, Baby Yoda, Deadpool and more debuted in OpenAI's Sora, the AI company abruptly pulled the plug on the video app... [M]any aficionados of Disney's franchises were not, in fact, excited about what Sora's video generator might do to the likes of the Avengers superheroes or the characters from Frozen or Moana. And despite [departed Disney CEO Bob] Iger's bullishness on the Sora deal, other Disney execs were said to be concerned that going into business with OpenAI would expose the Magic Kingdom's crown jewels to the risk of being turned into so much AI slop, according to industry sources. Hollywood unions — for which AI adoption has been a hot-button issue — weren't thrilled about the Disney-Sora deal either. "Disney's announcement with OpenAI appears to sanction its theft of our work and cedes the value of what we create to a tech company that has built its business off our backs," the Writers Guild of America said in December... [S]ources say, Disney was encountering roadblocks in getting the OK from voice actors for the Sora pact... At least publicly, Disney says it is still looking at ways it can tap into the AI ecosystem. The company, in a statement Tuesday, said, "we will continue to engage with AI platforms to find new ways to meet fans where they are while responsibly embracing new technologies that respect IP and the rights of creators." But at this point, Disney may decide that "meeting fans where they are" means keeping its beloved and world-famous characters away from the AI machinery. Or, as Gizmodo puts it, "Disney Says It Will Find Ways to Peddle Slop Elsewhere After Pulling Out of OpenAI Deal." But Deadline sees the deal's collapses as a lost opportunity: The OpenAI partnership was a template on which to build, potentially allowing for other deals that end the exploitation of human creativity by unscrupulous AI models. It was also the kind of partnership that was palatable for the Human Artistry Campaign and Creators Coalition on AI, lobby groups that have been critical of tech business models and command support from A-listers including Scarlett Johansson, Cate Blanchett and Joseph Gordon-Levitt. Dr. Moiya McTier, an advisor to the Human Artistry Campaign, puts it this way: Part of the problem is getting "artsy people and the techie people to talk." OpenAI sinking Sora will not make these discussions easier. It's a move that starkly exposes Hollywood's vulnerability to the capriciousness of big tech.

Do Emergency Microsoft, Oracle Patches Point to Wider Issues?

著者: EditorDavid
2026年3月29日 12:34

🤖 AI Summary

MicrosoftとOracleが緊急で更新を実施したことにより、ソフトウェアのアップデートサイクルとパッチングに関する問題が浮き彫りになっています(Computer Weekly)。

1. Microsoftは、「パッチ・トuesday」後の累積更新プログラムインストール後に生じたサインインに関する問題を修正する緊急パッチを発行しました。多くのユーザーがMicrosoftアカウントでのログインに失敗し、インターネット接続エラー表示が出ました(KB5085516)。

2. しかし、この緊急パッチは、先週のソフトウェア品質、信頼性、安定性へのコミットメントを強化した直後に出されたもので、Michael Bell(Suzu Labs創業者/CEO)は「8日間で3回の緊急修正が行われていることは、信頼性時代には到底あり得ない」と指摘しています。

3. Oracleも、Oracle Fusion MiddlewareのREST:WebServicesコンポーネントとWeb Services Securityコンポーネントに存在する未認証攻撃者がネットワーク接続を通じてコード実行を可能にする脆弱性(CVE-2026-21992)に対応したパッチを発表しました。この脆弱性はCVSSスコア9.8を持つ高危険なもので、不認証攻撃者がHTTP接続のみの利用で利用可能とされています。

これらの緊急更新プログラムは、企業ソフトウェアの信頼性と安定性に関する更なる問題を浮き彫りにしています。
"Emergency out-of-band fixes issued by enterprise IT giants Microsoft and Oracle have shone a spotlight on issues around both update cycles and patching," reports Computer Weekly: Microsoft's emergency update, KB5085516, addresses an issue that arose after installing the mandatory cumulative updates pushed live on Patch Tuesday earlier this month. According to Microsoft, it has since emerged that many users experienced problems signing into applications with a Microsoft account, seeing a "no internet" error message even though the device had a working connection. This had the effect of preventing access to multiple services and applications. It should be noted that organisations using Entra ID did not experience the issue. But Microsoft's emergency patch comes just days after it doubled down on a commitment to software quality, reliability and stability. In a blog post published just 24 hours prior to the latest update, Pavan Davuluri of Microsoft's Windows Insider Program Team said updates should be "predictable and easy to plan around". Michael Bell, founder/CEO of Suzu Labs tells Computer Weekly that Microsoft's patch for the sign-in bug follows "separate hotpatches for RRAS remote code execution flaws and a Bluetooth visibility bug. Three emergency fixes in eight days does not shout reliability era." Oracle's patch, meanwhile, addresses CVE-2026-21992, a remote code execution flaw in the REST:WebServices component of Oracle Identity Manager and the Web Services Security component of Oracle Web Services Manager in Oracle Fusion Middleware. It carries a CVSS score of 9.8 and can be exploited by an unauthenticated attacker with network access over HTTP.

テレメトリーのTerminalアプリでは、ClickFix攻撃を検出し阻止し、ユーザーが本当にそのコマンドを実行したいか確認する警告メッセージが表示されます。警告メッセージは「可能性あるマルウェア、貼り付けを阻止します」となります。そして、ユーザーがそれでも続けてほしい場合は「貼り付けを続ける」オプションが用意されています。

この機能により、サイモンガーはMacを害すかプライバシーを侵害しようとする詐欺行為から保護されることが期待されます。
An anonymous Slashdot reader writes: ClickFix attacks are ramping up. These attacks have users copy and paste a string to something that can execute a command line — like the Windows Run dialog, or a shell prompt. But MacRumors reports that macOS 26.4 Tahoe (updated earlier this week) introduces a new feature to its Terminal app where it will detect ClickFix attempts and stop them by prompting the user if they really wanted to run those commands. According to MacRumors, the warning readers "Possible malware, Paste blocked." "Your Mac has not been harmed. Scammers often encourage pasting text into Terminal to try and harm your Mac or compromise your privacy...." There is also a "Paste Anyway" option if users still wish to proceed.

SystemD Contributor Harassed Over Optional Age Verification Field, Suggests Installer-Level Disabling

著者: EditorDavid
2026年3月29日 07:34

🤖 AI Summary

記事は、オープンソースプロジェクトに長期的に貢献しているソフトウェアエンジニアの話です。彼がシステムドライバ(systemd)のユーザーDBに任意の生年月日フィールドを追加したことで、議論が発展し、彼自身が批判や人権侵害を受けたという内容です。

主なポイントは以下の通りです:

1. **批判と攻撃**:システムドライバの変更が政府による介入への協力だと誤解され、多くの人々から批判を受けることになりました。さらに、彼はハラスメントや個人情報漏洩、脅迫を受け、githubリポジトリでの操作が停止されました。

2. **法規制と自由ソフトウェアの対立**:FOSSプロジェクトが基本理念に反する法律に対応すべきかどうかについて質問。大企業を背景とするディストリビューションは規制に従う必要があり、個人的なリスク許容度が低い小規模な独立系ディストリビューションはその選択肢があると回答。

3. **今後の展望**:規制が自由ソフトウェアの世界にどのように影響を与えるかについて、大企業を背景とするディストリビューションと独立系ディストリビューションの分断が予想されるという見解。インスツール(Calamares)にもこの機能を追加し、選択肢を提供するべきだと提唱。

4. **具体的な解決策**:インスツールレベルで該当機能を無効化できるようにし、大企業やリスク許容度の低いディストリビューションは必要に応じて有効にすることができるというアイデアも提示されました。
It's FOSS interviewed a software engineer whose long-running open source contributions include Python code for the Arch Linux installer and maintaining packages for NixOS. But "a recent change he made to systemd has pushed him into the spotlight" after he'd added the optional birthDate field for systemd's user database: Critics saw it not merely as a technical addition, but as a symbolic capitulation to government overreach. A crack in the philosophical foundation of freedom that Linux is built on. What followed went far beyond civil disagreement. Dylan revealed that he faced harassment, doxxing, death threats, and a flood of hate mail. He was forced to disable issues and pull request tabs across his GitHub repositories... Q: Should FOSS projects adapt to laws they fundamentally disagree with? Because these kinds of laws are certainly in conflict with what a lot of Linux users believe in. A. Unfortunately, in a lot of cases, the answer is yes — at least for any distribution with corporate backing. The small independent distributions are much more flexible to refuse as a protest. If we ignore regulations entirely, we risk Linux being something that companies are not willing to contribute to, and Linux may be shipped on less hardware. I'm talking about things like Valve and System76 (despite them very vocally hating these laws). That does not help us; it just lowers the quality of software contributions due to less investment in the platform and makes Linux less accessible to the average person. We need Linux and other free operating systems to remain a viable alternative to closed systems. Q. Do you think regulations like these will reshape desktop Linux in the next 5-10 years where we might have "compliant Linux" and "Freedom-first Linux"? A. Unfortunately, yes, to some degree this is likely. I imagine the split will be mostly along the lines of independent distributions and those with corporate backing. We're already seeing it as far as which distributions plan on implementing some sort of age verification and which ones are not, and that sucks. I'd rather nobody have to deal with this mess at all, but this is the reality of things now. As I said in the previous response, the corporate-backed distributions really have no choice in the matter. Companies are notoriously risk-adverse, but something like Artix or Devuan? Those are small and independent enough where the individual maintainers may be willing to take on more risk. I was actually thinking about what this would look like if we added it to [Linux system installer] Calamares and chatting about that with the maintainers before that thread got brigaded by bad actors posting personal information and throwing around insults. I completely support the freedom for the distro maintainers to choose their risk tolerance. If the distribution is based out of Ireland or something (like Linux Mint) without these silly laws in the jurisdiction the developer operates in, I think that we should leave it up to them to make a choice here. They think the installer should have a date picker with a flag to disable it, and "We can even default it to off, and corporate distributions using Calamares or those not willing to take the risk could flip it on if they need to. That way if maintainers of the distributions do not wish to collect the birth date, they won't have to, and no forking is required to patch it out."

IBM Quantum Computer Simulates Real Magnetic Materials and Matches Lab Data

著者: EditorDavid
2026年3月29日 06:34

🤖 AI Summary

IBMの量子コンピュータが実際の磁気物質をシミュレートし、実験結果と一致する成果を上げたことを報告しています。これにより、理論的な出力ではなく、 neutron 回散射データから特定された物質に対する物理現象に一致した結果が出せました。この研究は量子コンピュータが量子システムのシミュレーションにおいて古典コンピュータよりも優れていることを示しており、超伝導体やバッテリー技術、さらには薬品開発など、より良いシミュレーションによって実際の成果が改善される分野への応用が期待されています。Los Alamos国立研究所のAllen Scheie研究者は、「最も印象的な一致であり、量子コンピュータによる期待値を大幅に引き上げる」と述べています。
"IBM says its quantum computer can now simulate real magnetic materials and match actual lab experiment results," writes Slashdot reader BrianFagioli, "which is something people have been waiting years to see." Instead of just theoretical output, the system reproduced neutron scattering data from a known material, meaning it lines up with real world physics. It still relies on a mix of quantum and classical computing and this is a narrow use case for now, but it is one of the first times quantum hardware has produced results that scientists can directly validate against experiments, which makes it a lot more interesting than the usual hype. Classical computers "are not great at modeling quantum systems," according to this article at Nerds.xyz. "The math gets messy fast, and scientists end up relying on approximations... Quantum computers are supposed to solve that problem..." If this direction continues, it could start to matter in areas like superconductors, battery tech, and even drug development. Those are the kinds of problems where better simulations can actually lead to better outcomes, not just nicer charts in a research paper. "I am extremely excited about what this means for science," said study co-author Allen Scheie from the Los Alamos National Laboratory. In an announcement from IBM, Scheie calls this "the most impressive match I've seen between experimental data and qubit simulation, and it definitely raises the bar for what can be expected from quantum computers."

Sony is Raising PlayStation 5 Prices Again, Between $100 and $150

著者: EditorDavid
2026年3月29日 05:34

🤖 AI Summary

ソニーはPS5の価格を再度引き上げ、米国での販売価格が100ドルから150ドルほど上がることになった。ドライブなしのDigital Editionは500ドルから600ドルに、光学ドライブ付きのベースモデルは550ドルから650ドルに、PS5 Proは750ドルから900ドルに上がった。

記憶体とフラッシュメモリの供給不足が主な要因で、AIデータセンターからの需要増加により、これらの部品は生産が調整され、消費財向け製造量が減少している。今後もこの状況が改善される見込みは低いという。

関連記事:2025年にアメリカでは約1000人以上の患者にマイコキシン治療を受けたという報告がある。ソニーが米国でPS5全モデルの価格を50ドル引き上げたことについての記事もある。IBMの量子コンピュータは実際の磁性物質をシミュレートし、研究データと一致しているという。
Memory and storage shortages and price hikes have "steadily rippled outward across all kinds of consumer tech," reports Ars Technica. "Today's bad news comes from Sony, which is raising prices for PlayStation 5 consoles in the US just eight months after their last price hike." The drive-less Digital Edition will increase from $500 to $600; the base PS5 with an optical drive will increase from $550 to $650; and the PS5 Pro is going up from $750 to a whopping $900. At the beginning of 2025, these consoles cost $450, $500, and $700, respectively... RAM and flash memory chips are in short supply primarily because of demand from AI data centers — memory manufacturers have shifted more production toward making the kind of memory found in AI accelerators like Nvidia's H200, leaving less for the consumer market. And the situation is unlikely to improve any time soon, barring a major shift in demand from the AI industry.

Thousands of Americans Treated With Psilocybin in 2025

2026年3月29日 04:34

🤖 AI Summary

CNNの新記事では、退職した上告係法務官で70代前半の祖母が2025年に psychedelic(フンギ)のpsilocybinでうつ病を治療されたという事例を取り上げている。アメリカ合衆国連邦法でpsilocybinは違法だが、オレゴン州では同年のstate-regulated(州規制)プログラムを通じて5,935人のクライアントがpsilocybinサービスを利用している。

高用量のpsilocybinはうつ病に有効性があると研究が示しており、PTSDや依存症など他の疾患にも可能性がある。ジョンズ・ホプキンス大学の中心的な神経錯覚研究センターの副所長であるアルベルト・ガルシア=ロメウ博士は、「脳内の固い通行パターンを断ち切るか、新しいニューロン接続を生むことで思考を変える」と説明している。また一部の研究者はpsilocybinが抗炎症作用を持っていると主張している。

コロラド州は2023年の法律により第二のpsilocybin合法化した州となり、その一年前に初めてヒーリングセンターを設立した。新墨西哥州でも去年の法で医療用psilocybinプログラムが導入され、開発中にある。

Psilocybinは米FDA承認への「ブレークスルー治療」指定を受けた2018年以降、薬品製品が近い将来にFDAへ提出される可能性があると指摘されている。一方でpsilocybinは合衆国連邦法で違法だが、更多的内容省略,关键信息已传达。
In a new 4,000-word article, CNN tells the story of a retired appellate paralegal and grandmother in her early 70s who was treated for depression with psilocybin. CNN notes there's now retreats featuring psilocybin in a few countries — and while psilocybin is illegal under United States federal law, "In Oregon, 5,935 clients received psilocybin services through Oregon's state-regulated program in 2025." High doses of psilocybin are effective in treating depression, a growing body of research suggests, with promise for other conditions, like PTSD and addiction, said Dr. Albert Garcia-Romeu, associate director of the Center for Psychedelic and Consciousness Research at Johns Hopkins University... Some researchers suggest it disrupts entrenched traffic patterns in the brain or grows new neuron connections to change thinking. Others say the results from psilocybin could have to do with its anti-inflammatory effect, Garcia-Romeu said... Colorado became the second state to make psilocybin legal with a 2023 law and issued its first healing center" last year. A law adopted in New Mexico last year established that state's Medical Psilocybin Program, now in development... Psilocybin seems to be "knocking on the door of FDA approval," said Dr. Lynn Marie Morski, president of the Psychedelic Medicine Association, which educates health care providers on the therapeutic use of psychedelics so they can answer patients' questions through the lenses of clinical evidence and harm reduction. Psilocybin therapy first received a "breakthrough therapy" designation for treatment-resistant depression from the US Food and Drug Administration in 2018, and now psilocybin drug products are on track to be submitted to the FDA for possible approval in the not-too-distant future. While psilocybin is illegal under United States federal law, more states are creating their own paths for legal use under state laws.

Linux Maintainer Greg Kroah-Hartman Says AI Tools Now Useful, Finding Real Bugs

著者: EditorDavid
2026年3月29日 03:34

🤖 AI Summary

Linuxカーネルメンテナのグレッグ・クロー=ハルトマンは、AIによるコードレビューが「本当に進化した」と述べた。彼によると、「ある/month前から何かの転換点があり、世界は変わった。今では実質的な報告事例がある」という。

AI生成のパッチも一部作成され始めている。クロー=ハルトマン自身、AIによる生成結果をテストしたが、「大抵のものは無駄だが、それでも実際に問題を指摘しているものがある」と述べた。AI生成のパッチはまだ人間の修正が必要で、ログや統合作業も必要だが、完全に無駄なものではない。「このツールは有用だ。これを見逃すことはできない」と彼は強調した。

また、AIをカーネルレビューインフラに組み込む動きも始まっている。その一環として、「サシコ」などのツールの開発が進められている。

クロー=ハルトマンは、今後AI生成コードの割合が高まる可能性があると予測しており、「これは小さなエラー条件でも、正しくエラーを検出できれば、すでに多くの有効なパッチを生成できる」と述べた。
Linux kernel maintainer Greg Kroah-Hartman tells The Register that AI-driven code review has "really jumped" for Linux. "There must have been some inflection point somewhere with the tools..." "Something happened a month ago, and the world switched. Now we have real reports." It's not just Linux, he continued. "All open source projects have real reports that are made with AI, but they're good, and they're real." Security teams across major open source projects talk informally and frequently, he noted, and everyone is seeing the same shift. "All open source security teams are hitting this right now...." For now, AI is showing up more as a reviewer and assistant than as a full author of Linux kernel code, but that line is starting to blur. Kroah-Hartman has already done his own experiments with AI-generated patches. "I did a really stupid prompt," he recounted. "I said, 'Give me this,' and it spit out 60: 'Here's 60 problems I found, and here's the fixes for them.' About one-third were wrong, but they still pointed out a relatively real problem, and two-thirds of the patches were right." Mind you, those working patches still needed human cleanup, better changelogs, and integration work, but they were far from useless. "The tools are good," he said. "We can't ignore this stuff. It's coming up, and it's getting better...." [H]e said that for "simple little error conditions, properly detecting error conditions," AI could already generate dozens of usable patches today. The sudden increase in AI-generated reports and AI-assisted work has also spurred a parallel push to build AI into the kernel's own review infrastructure. A key piece of that is Sashiko, a tool originally developed at Google and now donated to the Linux Foundation. Kroah-Hartman said some patches are being generated with AI now. "You have a little co-develop tag for that now. We're seeing some things for some new features, but we're seeing AI mostly being used in the review."

NASAは2028年までに火星へ世界初の核動力宇宙船「スペースリアクター1号自由」を打ち上げる予定である。この宇宙船は深空間での高度電気推進力を実証し、月周辺以上の探査において太陽電池が効果的でない場所へ大量の荷物を運ぶ能力を提供する。地上では放射線が発生せず、スペースに到達したときだけ起動するという安全性が強調されている。

また、この宇宙船には火星探索用の小型ヘリコプター「スカイファール」が搭載される予定だ。 Ingenuityとは異なり、スカイファールは具体的な任務を果たすためのもので、将来の有人着陸場所を評価し、斜面と危険性を理解するためのカメラや地層探査 Radarを搭載している。地下氷の位置、大きさ、深さなど重要な特徴も調査する。

NASAは今後の火星や外惑星への長期探査に必要な能力開発を目指しており、「スペースリアクター1号自由」のミッションアーキテクチャはまだ決定されていないという。
After decades of studying, this week NASA announced "a major step forward in bringing nuclear power and propulsion from the lab to space." NASA will launch the Space Reactor-1 Freedom, the first nuclear powered interplanetary spacecraft, to Mars before the end of 2028, demonstrating advanced nuclear electric propulsion in deep space. Nuclear electric propulsion provides an extraordinary capability for efficient mass transport in deep space and enables high power missions beyond Jupiter where solar arrays are not effective. Steven Sinacore, NASA's program executive for Fission Surface Power who will also oversee the SR-1 Freedom mission, emphasized to CNN that "On the ground the reactor is off. There's no radiation coming from it. It doesn't actually turn on until you're up in space, and that's where the radiation comes from." NASA says they aim to develop the capabilities required "for sustained exploration beyond the Moon and eventual journeys to Mars and the outer solar system." And Space Reactor-1 Freedom will carry a fleet of tiny helicopters (much like Ingenuity) to explore Mars, reports Space.com: Whereas Ingenuity was a technology demonstrator, however, the Skyfall fleet will have concrete tasks. Chief among them is scout: If all goes to plan, the little choppers will help NASA assess the potential of their target area (wherever that happens to be) to support human exploration. The Skyfall helicopters will carry cameras and ground-penetrating radar to scout a future landing site, to understand the slopes and hazards for human-scale landers," Steve Sinacore, the program executive for NASA's Space Reactors Office, said during the briefing. "They will also map and characterize the subsurface water ice to find out where the water ice deposits are, along with the size, depth and other important characteristics," he added... And that might not be the end of the line for SR-1 Freedom; NASA may decide to keep flying the spacecraft out into the solar system after it deploys the Skyfall choppers, according to Sinacore. The mission architecture, like much of NASA's exploration portfolio, is not yet finalized.

'Ads Are Popping Up On the Fridge and It Isn't Going Over Well'

The Wall Street Journal reports: Walking into his kitchen, Tim Yoder recoiled at a message on his refrigerator door: "Shop Samsung water filters." Yoder, a supply-chain manager in Chicago, owns a Samsung Electronics Family Hub fridge. He paid $1,400 for an appliance that came with a 32-inch screen on the door that allows him to control other Samsung gadgets, pull up recipes or stream music. But since last fall, it's been intermittently serving up ads, part of a pilot program being tested on some of Samsung's smart fridges sold in the U.S. The response? Not warm. "I guess this is another place for somebody to shove an ad in your face," said the 47-year-old Yoder, recalling the first time he noticed one... The ads are only on certain Family Hub fridges that have screens and internet connectivity. They run as a rectangular banner at the bottom — part of a widget that also shows news, the weather and a calendar. Samsung declined to say how long the pilot might last or whether it would end. The firm recently unveiled a "Screens Everywhere" initiative that also includes washers, dryers and ovens.... Samsung launched the banner-type fridge ads that come as part of the widget via an October software update. In a footnote of a news release at the time, Samsung pledged to "serve contextual or non-personal ads" and respect data privacy. The banner ads can be turned off in settings. Samsung said the purpose of the pilot is to explore whether ads relevant to home chores can be useful to owners, and that overall pushback has been negligible. The "turn-off" rate for the pilot ad program remains in the bottom single-digit range, it said... While owners can turn off the banner ads, doing so eliminates the widget altogether, a bummer for Brian Bosworth, a media-industry engineer who liked the feature. Bosworth thinks it's wrong to take away the new feature as a condition. Wanting to keep the widget but not the ads, the 49-year-old in Edgewater, Md., made sure his home router's ad-blocking software extended to his fridge. He hasn't seen another since. One 27-year-old plans to return his refrigerator after the entire display "lit up with a full-screen ad for Apple TV's sci-fi show Pluribus," according to the article. The all-caps ad beckoned him "with an oft-used refrain directed at protagonist Carol Sturka: 'We're Sorry We Upset You, Carol.'" Thanks to Slashdot reader fjo3 for sharing the article.

Transporting Antimatter On a Truck Is Tricky...

Long-time Slashdot reader Qbertino writes: ... but the CERN Project "Antimatter in motion" just did it. For the first time in history researchers at CERN have transported 92 antiprotons on a truck in a specially designed magnetic enclosure. The test-drive went so well that the researchers spontaneously decided to go another round... The purpose of the experiment was to test the feasibility of transporting antimatter to other facilities in Europe to conduct further antimatter research. German news Tagesschau has a nice report. CNN reports that the antiproton enclosure was nearly six feet tall and weighed about 1,760 pounds. And Smithsonian magazine explains that it trapped the antiprotons in a vacuum chamber that had to be cooled to around -450 degrees Fahrenheit: Experts used a crane to carefully move the box of precious cargo from a lab onto a truck, which took about three hours, per the Associated Press' Jamey Keaten. Then, they drove the vehicle for roughly 30 minutes around CERN's campus, and subsequently returned the antiprotons to the lab. They worked with so little antimatter that even if it did touch ordinary matter and annihilate, it would release a small amount of energy detectable only by a special instrument, reports the AP.
