🤖 AI Summary

タイトル:Windowsバックドア「Sleepwalker」は魔術パケットにより起動され、メモリに潜んで指令を待つ

要点:
1. バックドア「Sleepwalker」は特定のネットワークパケット(「魔術パケット」)で起動し、それが到着するまで静かにメモリに潜んでいる。
2. 対象となるパケットには、バックドア独自の指令言語で書かれた短いプログラムが含まれる。
3. 指令言語は23インストラクションで構成されており、コードを直接メモリ上で実行したり、データを移動したりできるなど機能が豊富。
4. 対象となるホストアドレスとしてVMwareのVMCI(Virtual Machine Communication Interface)が使用できることも特徴的。
5. バックドアは64ビットWindows DLLファイル内に隠され、Microsoftのdpapi.dllを模倣している。実際のdpapisvc.dllへのリダイレクトを試みるなど、高度な脱皮技術を持つ。

詳細:
- 通常バックドアはコマンド&コントロールサーバーと通信し始めるが、「Sleepwalker」はネットワークトラフィックに潜んで特定のパターンを見つける。
- テクニカル分析では、感染されたまま外部に接続を行わないため、一般的なセキュリティツールには見つからない可能性があることが指摘されている。
"The Register has a story about a Windows backdoor that waits silently in memory for a 'magic packet' before springing into action," writes Slashdot reader fred133. "No outgoing traffic, just waiting..." From the report: Like a sleeper cell awaiting activation, a never-before-seen Windows backdoor dubbed Sleepwalker waits silently in memory for one specifically crafted network packet to wake it up and deliver commands using the malware's 23-instruction language. The commands can do everything from running code directly in memory to moving data off the computer. Malware researcher Dominik Reichel discovered the passive backdoor, which also has its own command language, and detailed Sleepwalker in a technical analysis on Monday. "What makes it worth writing up is what that packet carries: not a readable command, but a short program written in a command language of the backdoor's own design," Reichel said. "Its 23 instructions cover scheduling, several ways to move data, staged file delivery and running code directly in memory. Recovering the encryption key is not enough to understand one of these programs. The internal command language must be reverse engineered as well." In addition to having its own command language, it's also notable that the remote host can be a VMware VMCI target instead of a normal network address. "Taken as a whole, the approach here is consistent with a targeted, well-resourced operation rather than an opportunistic one," Reichel wrote. The malware, hidden inside a 64-bit Windows DLL file, impersonates Microsoft's dpapi.dll, part of Windows' data protection API for protecting sensitive data. It exports the same seven functions as the real dpapi.dll, but attempts to forward calls to a file named dpapisvc.dll, which is not a real Windows component. The file also has a forged ESET Management Agent version resource, and loads via side-loading into ERAAgent.exe, the Windows executable for ESET Management Agent. After confirming that its host process is named ERAAgent.exe, Sleepwalker goes to sleep inside the computer's memory, which also helps it remain hidden from traditional anti-virus tools. Unlike most backdoors, which call back to an attacker-controlled command-and-control (C2) server and start receiving commands, Sleepwalker lies in wait, checking every packet that passes through the network looking for a specific pattern - this is called a magic packet. Once it sniffs out a packet that matches the exact pattern, the backdoor decrypts the data and treats it as a command. "Because the backdoor never sends anything out on its own and does not open any obvious listening port by default, tools that watch for connections to known-bad domains or unusual outbound traffic will not see anything unusual," Reichel wrote. "The absence of outbound connections to known-bad infrastructure does not rule out an infection, either. A machine can be fully compromised by this backdoor while producing nothing at all for a network monitor to flag."

AliExpress Leverages User Audio Systems For Fingerprinting

著者: BeauHD
2026年8月25日 16:00

🤖 AI Summary

AliExpressはユーザーの音響システムを利用し、指紋認証を行う手法を採用していることが明らかになりました。開発者の「laserphile」によると、アリエクスプレスのサイトがWebAudio APIを使用して、不可聴の音声信号を放送し、それぞれのデバイスが信号を処理する微妙な違いを測定することで、ユーザーを特定する独自の指紋を作成しているとのこと。Bluetoothヘッドフォンが一時的に停止することや、画面サイズやネットワークデータなど、幅広い情報も収集されていると報告されています。

この手法は不可視かつ非同意で行われており、プライバシーに重大な影響を及ぼします。開発者は問題を解決するためにはプライバシーオリエンテッドのブラウザを使用することを推奨しています。FirefoxやBraveといったブラウザでは、この種の追跡を制限またはブロックすることが可能です。

要するに、AliExpressはユーザーのデバイス情報を無断で収集し、指紋化することでトラッキングを行っているという点が本記事の主な内容です。
A developer says AliExpress is using the browser's WebAudio API to help fingerprint users by playing inaudible audio and measuring tiny differences in how their devices process it. CyberNews reports: The developer, "laserphile," wrote on their blog that they recently ran into some weird issues with their Bluetooth headphones. They couldn't play music via their phone when, at the same time, the AliExpress website was open on their PC. The headphones, laserphile explained, support multipoint Bluetooth audio so they can be connected to the PC and phone at the same time, for instance, playing music on the phone and announcing notifications through the PC. "Shortly after loading the AliExpress homepage, audio from my phone would stop playing. Closing the AliExpress tab fixes it immediately," the developer said in the blog post. "Muting the tab/Firefox/Windows does not help, and there is no visible video, music, or other media playing on the page. This seemed suspicious enough to investigate." It turns out that Alibaba has been secretly leveraging AliExpress users' audio systems to track them and build detailed fingerprints of them. [...] The AliExpress site was using the browser's WebAudio API to run invisible sound waves at zero volume. By measuring tiny hardware differences in how each PC processed those signals, the site created a unique digital fingerprint to track devices -- without user knowledge or consent. The secret audio path froze the developer's Bluetooth connection while covertly scraping hardware memory, screen dimensions, and network data in the background. The data collection extends beyond audio. Further inspection revealed that the same scripts also measure canvas, WebGL, hardware specs, WebRTC, mouse/touch events, and automation indicators. All of these form a broad device fingerprint that is sent back to Alibaba's telemetry servers. The simplest fix is to use a privacy-focused browser such as Firefox or Brave, which can limit or block this kind of fingerprinting. Brave goes further by randomizing fingerprint data and blocking the AliExpress tracking scripts involved.

World's Oceans Hit Highest Temperature On Record As El Nino Grows

著者: BeauHD
2026年8月25日 12:30

🤖 AI Summary

海は記録を超えるほど暖かくなり、人為的な気候変動と進行するエルニーニョ現象の影響を受けています。欧州宇宙探査技術庁(Copernicus)の気候サービスによると、太平洋極地以外の平均表層水温は9月24日に21.1℃に達し、過去最高を更新しました。これは3回にわたって2024年3月に記録された21.09℃を超えたものです。

データは海面下10メートル(約32フィート10インチ)の温度を使用し、浮標や船舶、衛星からの測定を組み合わせて得られた世界全体の推計値です。専門家たちは記録更新のタイミングが注目を集めています。通常、海面温度は毎年3月か4月に最も高い値となりますが、これは南半球の夏終わりと一致しています。現在エルニーニョ現象のピーク時期にはまだ早いにもかかわらず、海洋がすでに高温になっていることは懸念材料となっています。

南半球が地球の大半を覆しているため、平均海面温度に大きな影響を与えます。サウスハンプトン大学海洋研究所のジェイムズ・グリスト准教授は、「記録更新が既に発生していることは、エルニーニョの強さの早期指標である」と述べています。「全てが同じ状況であれば、2027年3月か4月にも再び記録を更新する可能性があります」とも付け加えました。
An anonymous reader quotes a report from the BBC: The world's oceans are hotter than ever recorded, new data suggests, as they suffer from human-caused climate change and the growing El Nino weather phenomenon. The average surface temperature of the planet's seas outside the polar regions hit 21.1C (70F) on Saturday, according to figures from the European Copernicus climate change service. That edges past the 21.09C recorded on three separate days in March 2024, and is far above average for the time of year. [...] The data is based on sea temperatures 10m (32ft 10in) below the surface, using measurements from buoys, ships and satellites, which are combined to produce a global estimate. While the margin of record is currently very small and any global estimate comes with uncertainties, scientists say its timing is particularly notable. Average worldwide sea temperatures tend to reach their yearly peak in March or April, which corresponds to the end of summer in the southern hemisphere -- and not in August. The southern hemisphere contains more of the planet's ocean surface than the northern hemisphere and so exerts a bigger influence on average sea temperatures. What is especially concerning to scientists is that the oceans are already so hot when the natural El Nino weather phenomenon is still some way off its expected peak. "The fact that we are already breaking records is an early indicator of how strong the El Nino is becoming," said Dr Jeremy Grist, senior research fellow at the National Oceanography Centre in Southampton. "All things being equal we might expect the ocean temperature record to be broken again in March [or] April 2027," he added.

SEC Investigating Near-Implosion of AI Hedge Fund

著者: BeauHD
2026年8月25日 07:00

🤖 AI Summary

アメリカ証券取引委員会(SEC)は、AI関連のヘッジファンド「Situational Awareness」の近乎崩壊を調査し、主要なウォール街銀行に対し取引や借入金に関する情報提供を求めている。このヘッジファンドは元OpenAI研究者のレオポルド・アシェンブレンナーによって設立され、300億ドル以上の資産を管理していたが、流動性の不足により大規模な株式売却が迫られた。

SECは小投資家を保護するために金融市場を監視しており、損失を出した投資会社に対して定期的に民事訴訟を行っている。Situational Awarenessに対する調査はまだ初期段階で、罰則や処罰につながるとは限らないという。Situational Awarenessは2年前に設立され、AIのboomに乗って急速に成長したが、高株価のAI企業の売上が下落し、従来型テクノロジー企業の株価が上昇するなど、多重のリスクにより資金不足に直面し、最終的にシティレーンに株式を格安で売り渡さざるを得なかった。

この記事は Slashdot から引用しています。関連情報として、トランプ政権によるH-1Bビザ申請料金引き上げやアマゾンのハードウェア価格上昇なども参照できるという。
The SEC is investigating the near-collapse of AI-focused hedge fund Situational Awareness, sending subpoenas to major Wall Street banks for details about the fund's trades, borrowing, and communications with lenders. The fund, founded by former OpenAI researcher Leopold Aschenbrenner, managed over $30 billion and borrowed tens of billions more before leveraged bets unraveled, forcing it to sell most of its stock portfolio to Citadel at a discount. The New York Times reports: The subpoenas asked for details on the timing of Situational Awareness's trades and for its communications with lenders about the money it was borrowing, also known as "leverage," two of those people said. The subpoenas additionally warned the banks to preserve any information regarding the San Francisco hedge fund. The S.E.C. oversees financial markets with an eye toward protecting small investors, and has brought civil cases regularly against investment firms that produced large losses. Any investigation into Situational Awareness would be at its earliest stages, and it's no guarantee that it would lead to fines or other punishment. The hedge fund has not been accused of wrongdoing. [...] Situational Awareness had a fast rise and an even quicker retreat. Founded just two years ago by Leopold Aschenbrenner, a former researcher at OpenAI, it rode the A.I. boom to soaring investment returns. To achieve those results, however, the fund relied on heavy borrowing, as well as complicated and expensive financial instruments that magnify gains -- and losses. The latter piled up quickly last month when the stock prices of publicly traded, high-flying A.I. companies dipped. At the same time, shares in more traditional technology companies -- which the hedge fund had been betting against -- rose, compounding the problem. Situational Awareness was forced into a fire sale. It wound up selling most of its stock portfolio to a rival, Citadel, at a discount.

Trump Admin Moves to Impose More Than $100K Fee For H-1B Worker Visas

著者: BeauHD
2026年8月25日 06:00

🤖 AI Summary

トランプ政権は、特定の新規H-1Bビザに対する年金額103265ドルを永久化する方針である。これにより、技術、教育、研究分野で高度な技能を持つ外国人労働者の雇用に依存する企業には大幅なコスト増が見込まれる。Reutersによると、「裁判所は今年6月にこの年金を違法と判断し、政権が収受できなくなった」とのことだ。また、ボストンの上告法院ではこの決定の検討が行われており、別の法院では主要企業団体による年金に対する挑戦に対する裁判官の妥当性も審理中である。

トランプ氏の暫定的な年金増額は今年9月に期限切れとなり、1年前から発布された。土曜日に連邦登録雑誌に公表された国土安全保障省の提案案によると、この年金が永久化される可能性がある。年内には finalize されるとみられる。

H-1Bプログラムは、米国企業が専門分野の研修を受けた外国人労働者を雇うためのもので、年間65,000件のビザと、修士以上学位を持つ2万件の別枠がある。これらのビザは通常2000ドルから5000ドル程度の手数料しかかかっていなかったが、トランプ氏の指示により大幅に増額された。

この年金は、留学生ビザを保有する外国人市民に適用されず、また現在のビザの更新に対しては適用されない。
The Trump administration is proposing to make permanent a $103,265 fee on certain new H-1B visas, dramatically increasing costs for employers that rely on highly skilled foreign workers in tech, education, and research. "A federal judge in June ruled that the fee was illegal and blocked the Trump administration from collecting it," reports Reuters. "A Boston-based appeals court is reviewing that decision while a different court considers whether a judge properly rejected a challenge to the fee by a major business group." From the report: Trump's temporary fee increase expires in September, one year after it was issued. The proposed rule by the U.S. Department of Homeland Security, posted in the Federal Register on Monday, would make a fee of $103,265 permanent. It could be finalized by the end of the year. The H-1B program allows U.S. employers to hire foreign workers with training in specialty fields and offers 65,000 visas annually, with another 20,000 for workers with advanced degrees, approved for three to six years. Those visas typically came with fees between $2,000 and $5,000 before Trump's order. The fee would not apply to visas granted to foreign citizens already in the United States on student visas, who make up a large share of new H-1B recipients, or to renewals of current visas.

🤖 AI Summary

台湾当局对涉嫌非法向中国出口高端AI服务器并伪造文件掩盖违规行为的9人提起诉讼,其中包括一名Nvidia高级经理和两名Supermicro员工。这些人在美国实施出口管制的情况下,试图规避相关法规。

据路透社报道,检察官没有透露姓名,但确认嫌疑人因“信任侵犯和伪造文件”被捕。目前尚有一名与案件有关联者潜逃,涉嫌挪用分销公司资金,协助中国获取受限的Nvidia芯片。

2022年起,美国要求出口半导体到中国需获得许可,目的是通过领先中国在AI竞赛中保护国家安全。Supermicro创始人Wally Liaw因涉嫌自2024年以来向中国非法输送价值约25亿美元的AI服务器被捕后,台湾展开了独立调查以了解详情。

调查显示,共谋者试图伪造文件,使130台B300服务器看似在台湾设施中安装和使用。但实际上74台最终被出口并交付给中国客户,另有56台则因海关检查异常未能交货。据台湾官员称,Nvidia经理与Supermicro员工在不同层面进行勾结以谋取巨额利润,非法出口高端服务器,增加了企业合规成本,并严重损害了国家的国际声誉。

Supermicro对此表示,公司将致力于保护先进技术和知识产权,并将继续与台当局合作,强化安全措施、提升供应链透明度和执行出口管制法律。
An anonymous reader quotes a report from Ars Technica: Taiwan has indicted nine people -- reportedly including an Nvidia senior manager and two Supermicro employees based in the country -- who allegedly helped forge documents to cover up illegal exports of high-end AI servers to China in violation of US export controls. On Monday, Reuters reported that prosecutors in Keelung did not release any names but confirmed that the suspects were "charged with breach of trust and document forgery." One suspect linked to a related case remains at large, accused of the "siphoning of funds from a distributor company involved" in helping China get access to restricted Nvidia chips. Since 2022, the US has required a license to export semiconductors to China, with the intent of protecting national security by staying ahead of China in the AI race. But after the US arrested Supermicro co-founder Wally Liaw in March for allegedly funneling $2.5 billion in restricted AI servers to China since 2024, Taiwan launched a separate probe to learn more about the scheme. Taiwan's investigation found that co-conspirators attempted to falsify documents to make it appear that 130 B300 servers were installed and in use at a Taiwan facility. But 74 of those servers "were ultimately exported and delivered to Chinese customers," Reuters reported, while the rest, 56, were intended to go to China but were blocked once Taiwanese customs officials "detected irregularities." According to Taiwan officials, Nvidia's manager and Supermicro employees "colluded with one another at various levels for enormous profit, illegally exporting high-end servers, increasing corporate compliance costs, and severely damaging our nation's international image." Supermicro said in a statement to PCMag: "Supermicro is committed to protecting our advanced technologies and intellectual property. We are working closely with Taiwanese authorities on recent events, which underscore the importance of continued collaboration across industry and government to strengthen safeguards, enhance supply chain visibility, and facilitate the enforcement of export control laws."

China Delays Ambitious Chang'e 7 Lunar Mission Until 2027

著者: BeauHD
2026年8月25日 03:00

🤖 AI Summary

中国は8月24日の打ち上げを延期し、嫦娥7号月面ミッションを2027年まで延期すると発表しました。この延期は悪天候によるもので、中国の宇宙飛行士団(CMSA)は「絶対的な安全」が求められるためと説明しています。科学アメリカンによると、米国と中国は月面有人帰還を目指している競争にあり、米国は1960年代に実現し他国では未達成のこの目標に向けてそれぞれ努力を続けているのです。

嫦娥7号は Shackleton 峡谷で氷結した水を探すために設計されており、ここは月南極近くの21キロメートル四方の坑です。これはこれまで任何の有人探査機が立ち寄ったことのない地域であり、水を探偵することが長期的な月面居住に不可欠な要素となっています。

Ars Technicaによると、延期の主因は台風ナーラによるもので、海南島と大陸中国を隔てる水路で進む台風ナーラは最大45マイルの風速を持っています。また、次回の打ち上げ窓口が2月や3月になるのは、極地着陸区の日照条件と90日間の月周観測が必要なミッション計画による可能性が高いです。

このミッションは米国と中国が月面基地を建設するために争う重要な地区に焦点を当てているため、どちらの国の先発権が争点となっています。
China has delayed its ambitious Chang'e 7 lunar mission until at least 2027 after scrubbing an August 24 launch. Poor weather conditions were likely a factor, with China's Manned Space Agency (CMSA) saying the decision reflects the need for "absolute safety." Scientific American reports: China and the U.S. are in a race to send humans back to the moon, a feat that that U.S. accomplished in the 1960s and that has never been achieved by any other country. Chang'e 7 is to play to a crucial part in China's ambitions: the probe is designed to search for frozen water in the Shackleton Crater, a pit that spans some 21 kilometers (13 miles) and sits beside the lunar south pole. No spacecraft has ever landed in that region, which scientists consider to be among the likeliest places to find water on the moon. Locating water that can be used by humans is vital to establishing any long-term lunar presence. NASA and China are eyeing the region to establish a crewed base -- and because this real estate is so precious, it matters who gets their first. Ars Technica notes in its reporting that the delayed launch was "most likely" due to Typhoon Narra, "which has 45 mph winds (equivalent to a moderate Tropical Storm) and continues to meander around in the waterway separating Hainan Island, where the spaceport is located, and mainland China." As for why the next launch window won't open until next February or March? "It likely is a combination of factors, including sunlight conditions in polar landing zones as well as the mission plan that requires a 90-day lunar orbit reconnaissance before landing," reports Ars. There's also a possibility, albeit an unlikely one, that "some technical issue was discovered at the last minute with either the complex Chang'e 7 payload, or the rocket."

🤖 AI Summary

アルツハイマー病の初めての血液検査がFDAで承認されました。このテストは40歳以上の症状のある患者に適用でき、アミロイドとタウというタンパク質のバイオマーカーを一つの血液サンプルから測定します。 PrecivityAD2は、これらを迅速に評価する単一血液検査で、プラズマAB42/40とp-tau217/np-tau217を質量 espectrometry を使用して測定し、結果を陰性、おそらく陽性、またはAD陽性とスコアリングします。この検査は一か月前にFDA承認された最初のものであり、現在3つ目の承認を得ました。PrecivityAD2は1,142人の症状のある成人を対象にした臨床検証研究で97.6%の精度を示しました。また、慢性腎臓病や糖尿病などの共病状態を持つ患者でも結果が一致しました。この検査は一般的な健康Screeningには適しておらず、認知機能の衰えがある患者向けです。これは早期診断、臨床試験の強化、精密医療と組み合わせ治療の基礎を築くために重要なステップとなるでしょう。
The FDA has cleared the first Alzheimer's blood test for symptomatic patients as young as 40. The test measures amyloid and tau biomarkers from a single blood draw and identified positive biomarkers with 97.6% accuracy in a validation study. New Atlas reports: PrecivityAD2 is a single blood test that quickly assesses the proteins amyloid and tau, using mass spectrometry to measure plasma AB42/40 and p-tau217/np-tau217. The results are then scored, qualifying as negative, likely positive, or positive for AD. "Just over a year ago, there were no FDA-cleared blood tests for Alzheimer's, and now we have three," Isobel Coleman, chief executive officer of the Alzheimer's Drug Discovery Foundation (ADDF), said in a statement. "This is a proof point that sustained, early investment in translational science plays a catalytic role in moving promising ideas from the lab to patients." In a recent clinical validation study, 1,142 symptomatic adults were tested using PrecivityAD2. The process accurately identified 97.6% of positive biomarkers. What's more, the results remained consistent even in patients with comorbidities like chronic kidney disease and diabetes, which can distort plasma amyloid samples. It's worth noting that the test isn't intended for general health screenings, but for patients who already show some cognitive decline. "As PrecivityAD2 and tools like it move further into clinical practice, they will enable earlier detection, sharpen clinical trials, and build the foundation for precision medicine and combination therapies," Coleman added.

2026年8月25日 01:00

🤖 AI Summary

humanoidロボットが北京で開催された「世界 humanoid ロボット大会」の100メートル競 walk 中、ウサイン・ボルトの世界記録より速い9.39秒で走破したというニュースです。開発元は北京市 humanoid ロボットイノベーションセンターで、同ロボットが Honor の Lightning に先行しました。大会では種目も多岐にわたり、サッカー、卓球、ボクシングなども行われます。

しかし、現段階では商業的な用途には使用されない見込みです。競走後に直接障害物に衝突し、一部は人間の援助を必要としながらコースから運び出されたという点に注意が必要です。

前年の大会では Tiangong Ultra が21.5秒で優勝していました。また、北京ではロボットハーフマラソンも開催され、Lightning が50分26秒で優勝しました。
この成果は昨年と比べて著しい進歩ですが、まだ商業的な活用には至っていないようです。
Two humanoid robots competing at the World Humanoid Robot Games in Beijing on Saturday ran the 100-meter dash faster than Usain Bolt's 9.58-second world-record time. "[T]he Tiangong Ultra humanoid robot completed the 100-meter dash in 9.39 seconds during a preliminary heat," reports Engadget. "Developed by Beijing Humanoid Robot Innovation Center, the record-holding robot overtook Honor's Lightning robot, which completed the sprint in 9.47 seconds. From the report: Despite the impressive finish times, don't expect these humanoid robots to be used for any commercial purposes yet. After their sprints, they slammed directly into pads and some even required human assistance to be stretchered off the course. However, it's still a major improvement from last year's inaugural World Humanoid Robot Games, where the Tiangong Ultra won the 100-meter dash in 21.5 seconds. Beijing has also hosted a humanoid robot half-marathon, where Honor's Lightning won in 50 minutes and 26 seconds, which also beat the pace of another human world record. "The World Humanoid Robot Games in Beijing kicked off August 22 and will run until the 26, hosting thousands of robot participants competing in more than just track and field events, including soccer, table tennis and boxing," adds Engadget.

🤖 AI Summary

Dr. Dreは、ギタリストやエミネムのヒット曲「The Real Slim Shady」など多くのヒット曲を生み出した7回のグラミー賞受賞プロデューサーで、人工知能(AI)を使って音楽を作ることに積極的です。ニューヨーク・タイムズのインタビューで、DreはAI反対派を「新しいことを学ぶのが難しい人々」だと表現しました。「私は脅威とは見えないし、作曲が苦手な人だけがそれを脅威だと感じる」と語りました。

また、ビーツ・バイ・ドレとの共同経営者であるジェミー・イオヴァインもAIの欠点はないと主張します。「良い音楽を作るために gifted な人々にAIを提供すれば、より良いアルバムが作れます」と彼は述べました。Dreは、自身もAIを使って「これまでの自分の作品との比較」をするために利用していると語っています。

さらに、多くのプロデューサーがAIを使用していることを認めていないにもかかわらず、「隠れたAIプロデューサー」と呼ばれるIovineはティムバランもその一人だと述べています。
An anonymous reader quotes a report from Gizmodo: Dr. Dre, the pioneering rapper and seven-time Grammy-winning producer behind hit songs like Tupac's "California Love" and Eminem's "The Real Slim Shady," is very much pro using artificial intelligence tools to make music. In an interview with the New York Times, Dr. Dre and Interscope Records co-founder Jimmy Iovine spoke about artificial intelligence's recent foray into music production, with the producer characterizing those who oppose AI song generation tools as "afraid of learning new things." "I don't see it as a threat. I think the only people that see it as a threat are the people who have trouble creating," Dr. Dre said. "I had a discussion with a few people a few days ago. They were against AI, and I'm like, 'OK, you sound like the person that would have been against the drum machine when it came out.' Or synthesizers, right?" [...] Iovine, the music executive and Dr. Dre's partner in Beats by Dre, for his part, says he doesn't "see the downside at all." "There will be some crappy music. There's crappy music now," Iovine told the NYT. "In the studio, when gifted people have AI, they're going to make better records." Dr. Dre said he uses AI in producing "as a tool to see what it would do with what I just did." The award-winning producer also said he is definitely not alone among his peers in his stance on AI either: many producers use AI but fear to admit it. Iovine calls them "closet AI producers," and says Timbaland, the four-time Grammy-winning singer-producer behind a long list of hits like "Promiscuous" with Nelly Furtado, is also one.

After 50 Years, Physicists May Have Finally Found a Particle Made of Pure Force

2026年8月24日 20:34

🤖 AI Summary

50年以上にわたる探求の末、物理学者が「ゴリラグレープ」のような量子力の粒子であるグールンを主成分とする特殊な粒子(グールンボール)を見つけることに成功したという報告がある。この研究は北京での加速器実験で得られた結果に基づいており、中国の南京大学のジン・シャン博士らのチームが主導した。

彼らは高エネルギー粒子衝突を解析し、X(2370)と呼ばれる既知の粒子がグールンボールであるという強い証拠を得た。この粒子は夸力学間力媒介子からなる唯一の特殊な粒子であり、「ゴリラグレープ」の一種として知られる。

研究結果はアーカイブに投稿され、ブラジルで開催された高エネルギー物理学国際会議で発表された。ジン博士は南中国朝報紙に、「この成果は強力相互作用を説明する理論が最も厳しい検証を通過し、物理世界の理解の境界を拡張する可能性がある」と述べた。

この研究は約50年のグールンボール探査から最も明確な実験結果であり、夸力学間力媒介子が新たな物質形態を作り出すという長年にわたる理論予測を支持している。しかし、より多くの実験が必要で、さらにこの特殊なグールンボールの原型を確認し制約するためには「粒子 smashing」を行う必要があると指摘されている。
Gluons are the quantum 'Gorilla Glue' involved in binding quarks together, ScienceAlert reminds us. But for nearly 50 years, physicists have hunted for "glueballs", exotic particles predicted by this theory of the strong interaction — the only type of particle in nature composed entirely of force mediators: Now, a collaboration working at a collider in Beijing says it has the clearest evidence yet that a known particle called X(2370) is dominated by one of these elusive states... Physicists sifted through the wreckage of high-energy particle collisions to find strong evidence of this glueball, made predominantly of gluons — massless force carriers of the strong interaction between quarks... The new evidence for this exotic, unstable glueball's ephemeral existence comes from a recent preprint on arXiv, presented at the International Conference on High Energy Physics in Brazil... This collaboration uses the Beijing Electron Positron Collider II, a particle accelerator and collider that smashes electrons into their antimatter counterparts, called positrons, to probe perplexing particle physics. The resultant glueball is an "unprecedented form of matter," says Jin Shan, a particle physicist at Nanjing University and one of the research team's leaders. "It not only enables the theory describing strong interactions to pass its most rigorous test, but also vastly expands the boundaries of our understanding of the physical world," he told Fan Chen at South China Morning Post... Previously, in a study published in the journal Physical Review Letters in 2024, the researchers analyzed 10 billion meson decay events. They measured the X(2370) particle's mass and spin parity — a property that dictates its interactions and almost-instantaneous decay — for the first time, finding complete agreement between their experimental values and predictions. Now, they've identified its additional decay modes and determined its flavor-singlet nature, "the most important characteristic of a glueball...." The authors describe their work as the clearest experimental result to emerge from nearly 50 years of glueball searches, supporting the long-standing theoretical prediction that gluons can bind together into a new form of matter. The discovery ""highlights advances in technology and analytical techniques that have recently revealed another decades-in-the-making physics mystery," the article points out. "More experiments are needed to further confirm and constrain the prototypes of the highly esoteric glueball; in other words, more particle smashing."

SCO Successor Xinuos Asks Court to Rehear Its Claims Against IBM/Red Hat Over Project Monterey

🤖 AI Summary

SCOの継承者であるXinuosは、IBMとRed Hatに対するプロジェクト・モンテレー関連の主張について再審を要求し、長期にわたるLinux著作権の法的対立がついに終わりを見せる可能性があると報じられています。

2021年にSCOの後継者であるXinuosは、IBMがProject Montereyのコードを提供した際には非独占的なライセンスしか持っていないことから、IBMがその約束を破ったことを主張しました。Xinuosはニューヨーク南区地方裁判所に訴訟を提起し、2023年8月10日に二審法廷で再考の機会を求める権利があると判示されました。

二審法廷は、当初の法律文書により再検討する時期ではないと判断しました。Xinuosがライセンス問題ではなく所有樁に関する主張を行ったことを指摘しています。Xinuosは全判事会による再考を望んでいますが、これは通常起こらないほどまれなケースです。

関連記事:2000年にSlashdotではSCOの一つの社長とのインタビューが行われました。 SCOは約50年前に起きた「誰がUnixの所有者か?」という訴訟に関連していると指摘しています。

The long legal battle over ownership of Linux "is closer than ever to ending," reports the Register, "after a panel of three judges ruled a claim against IBM and Red Hat isn't valid, and that time has expired for further action." In 2021, an heir to SCO settled with IBM for $14.25 million — a sum that reflects the fact SCO had for years failed to produce strong evidence to back its claims. Another of SCO's legal successors, Xinuos, filed a new claim that IBM should be on the hook because Big Blue knew it did not own the code it contributed to Linux but instead had a non-exclusive license to use it. Xinuos argued that when IBM contributed Project Monterey code to Linux [25 years ago], it breached that license. Xinuos eventually took that argument to the US District Court for the Southern District of New York — and failed to convince it that IBM and Red Hat had a case to answer. Xinuos appealed, and on August 10th the United States Court of Appeals for the Second Circuit decided [PDF] not to revisit the District Court's decision, agreeing that the original legalese governing Project Monterey means it's too late to re-litigate the matter. The Appeals Court also agreed that Xinuos tried to frame the case as a licensing issue but failed, instead arguing that the issue was really about ownership. That ain't all, folks, because Xinuos intends to file a petition to have the case re-heard by the full bench of the Court of Appeals. That hardly ever happens, unless the court finds significant errors or major legal issues that make a rehearing worthwhile. Law firm Kaplan says the Second Circuit has allowed reviews of less than 0.03 percent of the cases it has handled. So perhaps this matter is now close to a final resolution. Back in 2000 Slashdot interviewed one of the presidents of SCO.

One-Third of Web Pages are Now Written With AI, Says Pew Research

著者: EditorDavid
2026年8月24日 13:34

🤖 AI Summary

Pew Researchのシニアデータサイエンティストが、過去5年間の50万件以上の英語ウェブページをAI検出ツールで分析し、どれほどのページがAIによって書かれているかまたは編集されているかを推定した結果、全体の10%のページにAI著者特性が見られると報告しました。ChatGPTのリリース後、新規ウェブページの3分の1以上がAIによって著作者または大量に編集された可能性があることが判明しました。

また、ウェブ上でのAI作成テキストは一様ではありません。.comドメインの約10%のページがAI作成の兆候を示す一方で、.org、.edu、.govドメインでは4.6%、1%程度にとどまっていることがわかりました。

さらに、現在のインターネットと2023年の状況を比較した結果、エムダッシュが2倍、オックスフォードコマースが増えた(63%)、AIによって頻繁に使用される言葉(例:「delve」、「interplay」、「testament」)の使用頻度が2倍になり、ネガティブな平行比較もほぼ3倍に増加したことが明らかになりました。
A Pew Research senior data scientist analyzed 500,000 English-language webpages from the past five years with an AI detection tool to estimate how many were likely written or edited by AI: Of all the pages in this sample, 10% show significant signs of AI authorship... If we filter old webpages out of our samples and look at only the pages published after the release of ChatGPT, the trend is even more pronounced. In the July 2026 snapshot, signs of AI authorship can be found in over one-third of pages published after ChatGPT was released. This is in line with other studies that have shown that large shares of recently published pages on the internet were likely written or substantially edited by AI. AI-authored text is not evenly spread across the web. When ChatGPT was first released, the kinds of linguistic patterns that can signal AI authorship appeared at similar rates across the main top-level web domains (.com, .org, .edu and .gov). But in samples from 2026, around one-in-ten pages with a .com domain show signs of AI authorship — about double the share on .org domains (4.6%), and 10 times the rate on .edu or .gov domains (both around 1%). They even identified specific ways online text has changed, "comparing the internet of today to a snapshot from 2023." Em dashes appear twice as often Oxford commas increased 63%. Words used more frequently by AI (like "delve," "interplay" or "testament") have more than doubled in usage. "Negative parallelism" comparisons ("it's not just X, it's Y") have nearly tripled.

Could Mecha Comet's Linux PC-Phone Hybrid Be the Future of Linux Smartphones?

著者: EditorDavid
2026年8月24日 11:31

🤖 AI Summary

「Mecha Comet」というLinuxを基盤としたPCとスマートフォンのハイブリッドデバイスがKickstarterで334万ドルを集め、10月や11月に発送される予定です。このデバイスは、4インチのAMOLEDディスプレイ、マイク、スピーカー、SIM Tray、USBポート2基、ミニHDMIポートを搭載しており、重量とサイズはスマートフォンより少し大きいです。

開発者はShoaib Merchantで、同社は300以上の拡張機能モジュールやキーボード、ゲームパッド、I/Oブレークアウトなどのオープンハードウェア提供を予定しています。デバイス自体はUSB PD(Power Delivery)により外部電源から起動することも可能です。

Mecha Cometはカスタムなハードウェア最適化されたLinuxディストリビューションを搭載しており、使い手が「ポケットに持ち運べる専用のLinuxターミナル」のように利用できます。このデバイスには内蔵NPUがあり、AIワークフローの実行も可能です。

開発者の一人は、この製品が「Linuxスマートフォンの未来」と主張しています。彼自身は、このデバイスを使って遠隔操作を行うことを計画しており、リモートアクセスやデジタルデトックスにも適しているとします。
3,346 backers pledged $1,198,844 on Kickstarter to build the (modular) handheld Linux computer, the Mecha Comet. It's slightly bigger and heavier than your smartphone, with a 4-inch AMOLED display and loaded up with things like microphones, speakers, a SIM tray, two USB ports and a mini HDMI port. There's three separate kill switches for wifi, microphone and camera — plus a "boot mode" switch for the SD card, and even three pins for instant access to its debug console. It's now expected to ship in October or November (and is still available for preorder). Snap-in extensions include a keyboard (with programmable colors for its backlit keys), a gamepad, and a special IO Breakout that exposes the 40 pogo pins for modules, sensors, and MCUs. They're all open hardware, and founder Shoaib Merchant says "I'm looking forward to more community designs over the upcoming months." He shows the screen in action in a video on Kickstarter, demonstrating native apps like Music, Notes, Settings, and Files — as well as a Terminal app running on its color screen. A Linux correspondent at How-To Geek notes its ships "with a custom, hardware-optimized Linux distro out of the box," so "it's like having a dedicated Linux terminal in your pocket." And they argue the new device "could be the future of Linux smartphones." I should also mention that you don't necessarily have to use the battery; it can power on over USB PD without one. Overall, you're getting the same I/O you'd expect from a computer in a smartphone-like form factor, complete with modular input devices — and it's running Linux under the hood. For me, that's the most innovative gadget I've seen in the Linux hardware space in a long time... It's powerful enough to run most Linux terminal apps, which opens up a lot of possibilities. You're also getting an NPU built right into the SoC, which opens up the possibility for on-device AI workflows — something not possible in budget smartphones. Now, I personally plan to use it for SSHing into my main computer and home lab and operating them remotely. That's also why I'll be putting the LTE modem in the M.2 slot rather than an SSD — mobile data means I can reach my machines even when there's no Wi-Fi around. I also showed it to my partner, and she sees this as the ideal minimalist phone for digital detoxing. There's a built-in media player, a basic notes app, and you can even run Spotify from the terminal if you want.

The Global Race To Make a Practical Quantum Computer Just Took a Big Leap Forward

著者: EditorDavid
2026年8月24日 08:53

🤖 AI Summary

量子コンピューターの実用化を目指すグローバルな競争が大きく前進したと、Tech.Slashdot は報告しています。Quantinuum社(本社:イギリス・ケンブリッジ、アメリカ・ブルームフィールド)が開発した Helios システムは、 trapped ions を用いて動作し、98 の量子ビットを操作する最大規模の trapped-ion 量子コンピューターです。これにより、従来の QCCD マシンでは実現不可能だった複数タスク同時処理が可能となりました。

Helios システムは、四方向 X 接続部というハードウェアと、最適なルートを計算する Helios ランタイムというソフトウェアにより、大きな進歩を遂げています。この技術革新により、Helios は現存の最大級のスーパーコンピューターでも可能な方法で時間とエネルギー効率よく量子計算を行うことが可能になりました。

ただし、これらの実験はランダムなベンチマークテストに過ぎず、科学や商取引における実用的な量子計算を行うには、数百万の量子ビットを必要とする可能性があります。
It's "radically different from other quantum computers" reports Phys.org. The Helios system uses trapped ions — charged atoms suspended in free space using electromagnetic fields. But it operates with 98 qubits — making it the largest trapped-ion quantum computer built so far. Quantinuum, the company behind the device, is based in Cambridge, U.K., and Broomfield, Colorado. It demonstrated earlier machines operating on 32 qubits in 2023 and 56 qubits in 2025... It relies on two major advances — one in hardware and one in software. First, the four-way X junction lets the system handle several tasks at once rather than one at a time, which is much faster. That was impossible in earlier QCCD [quantum charge-coupled device] machines, which could only move data back and forth in a single line or loop. Second, judicious use of the freedom offered by the two dimensions of the X junction relies on new classical control software called Helios runtime, which plans the smartest, fastest route for moving and processing the data. Together, these represent a substantial advance in the engineering of quantum computers. An important consequence is that Helios can perform computations that cannot be performed even on the largest supercomputers using known methods within reasonable amounts of time and power consumption. This demonstrates the ability of this device and its successors to surpass the computational prowess of classical computers — although their algorithms and hardware are rapidly advancing, too. Having said that, Helios' computations have just been random benchmark tests, so the practical importance of this leap forward is still limited. To perform quantum computations of practical importance in science and commerce, even the most optimistic estimates suggest that quantum computers must be enormously bigger and better — of the order of a million qubits.

Amazonの Twitch テーリングサービスがユーザーのストリームをAI製品に使用することなくライセンスや承認を得ること無く利用したとして、クラスアクション訴訟に見舞われました。Engadget によると、Twitchは先月、ユーザーが「チャンネルコンテンツを使用してAmazon全体での生成AIコンテンツモデルの訓練を行いたいか」を選べるオプトアウト機能を追加しました。しかし、Mike Minton(社長製品責任者)はViewerの質問に対し、「もしオプインだったなら誰も選ばないだろう」と述べ、設定はデフォルトで有効でありユーザーが参加しない場合はオプトアウトする必要があると説明しました。最新のクラスアクション訴訟では、TwitchとAmazonはストリーマーを「別々の商業AI製品の無料トレーニング素材」として利用したとして契約違反を主張しています。
A class action filed this week accused Amazon's Twitch gaming service of using video streams to fuel its AI products without licensing or obtaining permission, reports Engadget: Earlier this month, Twitch Support posted on X that it added an option to opt out of "having your channel content used to train generative AI content models across Amazon." Shortly after, Twitch hosted an episode of its recurring Patch Notes stream where Mike Minton, the company's chief product officer, said "if it was opt-in, nobody would opt in," when asked by a viewer why the Twitch settings for AI training aren't opt-in but instead enabled by default, requiring users to opt out if they don't want to participate. Now, the latest class action lawsuit claims that Twitch and Amazon committed a breach of contract when the companies decided to use its streamers as "free training stock for separate commercial AI products."

OpenAI Faces Safety Scrutiny After Introducing 'ChatGPT For Teens'

著者: EditorDavid
2026年8月24日 05:59

🤖 AI Summary

OpenAI は、13〜17歳向けの ChatGPT 版をリリースし、自殺や自己傷害に関する内容、浪漫的または性的なチャットなどに対する保護機能が強化された。Tech 分析家の Carmi Levy 氏によると、このバージョンはユーザーの年齢推定を行い、不適切な体験を防ぐとともに、学習に役立つ機能も追加しているという。

しかし、Levy 氏は、「AI が完璧ではない」と指摘。AI は一部のユーザーを誤認する可能性があり、保護機能を回避しようとする者もいるため、完全な安全性とは言えないと述べた。さらに、このバージョンは親が子供のオンライン活動を監視する意欲を減退させる可能性があるとして、「逆効果」であると批判した。

CNN によれば、OpenAI は ChatGPT の不適切な会話が若者に被害を与えているとして訴訟に直面している。新機能には、90 分間の利用後に休憩を促す機能や、「静寂時間」や「学習時間」などの設定があり、ChatGPT は既存の保護機能を改善し、ユーザーから個人的感情表現を防ぐとともに、プライベートまたは機密な画像のアップロードに注意を叫ぶ機能も追加された。

この新バージョンは若者のオンライン安全を高める可能性があるが、専門家の多くは慎重な姿勢で受け止めている。OpenAI の親子コントロール機能を利用して子供の ChatGPT アカウントを確認することが推奨されている。
This week OpenAI launched a version of ChatGPT exclusively designed for teenagers between the ages of 13 and 17, reports CTV, "saying this version came with stronger protections around content related to mentions of suicide, self-harm and romantic or sexual chats." [Tech analyst Carmi Levy says] "What it's doing is it's using cues, it's sort of watching how you're using the tool, and it's trying to guess your age." Levy said if ChatGPT thinks a person has lied about their age when they first signed up, it will automatically put them into the Teens mode for protection. "It includes those sort of two things: prevent you from having experiences that are age inappropriate, and also add features that are aligned with academics, so that makes it easier to study, makes it less likely for you to cheat on an assignment, provide resources that that that allow you to learn more effectively," he said. Levy reminded users that this is still an application and a web service, which means it's constantly collecting personal information about the users' activities on the device and using the data to estimate their age... In the event a user is talking about self-harm, this new version will block the conversation and suggest additional help or call emergency or mental health services, Levy explained. It would do the same with violent content, eating disorders, engaging in dangerous activities, as well as explicit, sexual or graphic content. "It's using AI again to sort of parse out that conversation: 'are we headed in a in a significant direction? If so, throw up that guardrail, stop it from happening, redirect.'" However, the tech analyst said a number of people who have attempted to bypass the guiderails for research have succeeded in doing so "with a little bit of prompting.... I wouldn't call it 100% safe. That's kind of the catch-22 of the entire AI industry." This will lead parents to think that their children are safer and reduce the oversight on their online activities, which Levy described as a "perverse impact" that is "problematic." "Parents should not assume that OpenAI has their kids' best interests at heart. They should also not assume that these technologies are perfect. They will miss certain things, and they will also engage in what we call false positives," he said. "An adult who's legitimately is in the platform might be tagged as a child because the AI simply got it wrong." OpenAI's blog post says the new mode was designed for "preserving the ability to learn, create, and explore." But CNN notes the move "comes as OpenAI faces a string of lawsuits alleging that inappropriate conversations with ChatGPT contributed to the harm or deaths of young people." [New tools] include nudges for teen users to take a break if they've been active for 90 minutes within a three-hour window. OpenAI is also adding options for teens or parents to set "Quiet Hours" when ChatGPT is unavailable or "Study Hours" where ChatGPT's study mode for learning will be on by default. The company also said it has improved protections to prevent ChatGPT from expressing personal feelings toward a user. And it's adding reminders that caution teens to think twice if they try to upload a private or sensitive image to the chatbot... Nearly a third of American teens use AI chatbots daily, a Pew Research Center study published in December found. ChatGPT was by far the most popular AI chatbot in the survey, with more than half of those teens reporting having used it. Engadget shared this observation from Josh Golin, the executive director of Fairplay, a non-profit advocating for policies to make the internet safer for children. "Most parents, overwhelmingly, do not avail themselves of [parental oversight] tools, in part because they are deliberately made hard to find and use." Golin's group wanted to see testing of the tools first to see whether they led to better outcomes for teenagers. "The way this was just announced feels more like a response aimed at public relations than actual deep thinking about what kind of support [teens] need." And Mashable got a similar quote from Robbie Torney, head of AI/digital assessments for Common Sense Media's Youth AI Safety Institute. OpenAI's teen experience makes important safety commitments, but "What we really need now is evidence that they work, and we need this evidence, including our testing and the testing of others, before anyone, including parents, puts real trust in ChatGPT for Teens." Importantly, Torney said parents shouldn't assume their child is using ChatGPT for Teens. While OpenAI uses age estimation to place users in the age-appropriate version of ChatGPT, it can still mistake a user as older. Parents can be sure their child is using the teen version by linking their ChatGPT account to their child's and implementing OpenAI's parental control features. If a teen has previously lied about their age — and plenty do — they may continue to access the adult version of ChatGPT... Torney said caregivers must enact parental controls to receive notifications from OpenAI should their teen discuss suicide, self-harm, or acts of violence in immediate or dangerous ways... An OpenAI spokesperson said every notification is reviewed by a trained human before it's sent. The company strives to review notifications in under one hour.
