**要約(日本語)**

イーロン・マスクは、SpaceXが火星への移住計画よりも、月に「自己増殖型都市」を建設することを最優先にすると発表した。
- 月面での自律的に拡大できる都市は、10年以内に実現可能と見込んでいる。
- 火星への有人都市建設は5~7年先に開始する予定だが、文明の将来を守る観点から「月がより速く達成できる」ため、優先順位が低くなる。
- 同社は投資家に対し、2027年3月の無人月着陸を目指すと報告。
- なお、昨年は2026年末に無人火星ミッションを実施する計画を示していたが、今回の発表でそのスケジュールは後回しになる。

要するに、SpaceXは近い将来の人類の安全保障を重視し、まずは月で自己増殖型都市を構築することに注力する方針へと転換した。
"Elon Musk said on Sunday that SpaceX has shifted its focus to building a 'self-growing city' on the moon," reports Reuters, "which could be achieved in less than 10 years." SpaceX still intends to start on Musk's long-held ambition of a city on Mars within five to seven years, he wrote on his X social media platform, "but the overriding priority is securing the future of civilization and the Moon is faster." Musk's comments echo a Wall Street Journal report on Friday, stating that SpaceX has told investors it would prioritize going to the moon and attempt a trip to Mars at a later time, targeting March 2027 for an uncrewed lunar landing. As recently as last year, Musk said that he aimed to send an uncrewed mission to Mars by the end of 2026.

National Football League Launches Challenge to Improve Facemasks and Reduce Concussions

2026年2月9日 14:34

🤖 AI Summary

**要約(日本語)**

米国プロフットボールリーグ(NFL)は、スーパーボウル開催中に「HealthTECH Challenge」の次回募集を発表し、ヘルメットのフェイスマスク改良による脳震盪削減を目指すイノベーションコンテストを開催することになった。

- **目的**:フェイスマスクが衝撃を受けた際のエネルギー吸収性を高め、選手の脳震盪リスクを低減する新しい設計・素材を開発する。
- **背景**:これまでヘルメット本体のシェルやパディングの改良で脳震盪率は減少してきたが、2023シーズンでは選手の脳震盪の44%がフェイスマスクへの衝撃が原因(2015年の29%から増加)。フェイスマスク自体の大きな変化は見られなかった。
- **対象**:発明家、エンジニア、スタートアップ、大学・研究機関、既存メーカーなど。
- **支援内容**:選ばれた優秀チームには総額最大10万ドルの資金と、実用化に向けた専門家支援が提供される。
- **スケジュール**:受賞者は8月に発表され、メーカーはその後すぐに新技術をヘルメットへ組み込む予定。

NFLの選手安全担当副社長ジェフ・ミラー氏は、「ヘルメット本体の改良でシェル側の脳震盪は減っているが、逆にフェイスマスク側の割合が増えている。今こそフェイスマスクの革新が必要だ」とコメントしている。
As Super Bowl Sunday comes to a close, America's National Football League "is challenging innovators to improve the facemask on football helmets to reduce concussions in the game," reports the Associated Press: The league announced on Friday at an innovation summit for the Super Bowl the next round in the HealthTECH Challenge series, a crowdsourced competition designed to accelerate the development of cutting-edge football helmets and new standards for player safety. The challenge invites inventors, engineers, startups, academic teams and established companies to improve the impact protection and design of football helmets through improvements to how facemasks absorb and reduce the effects of contact on the field... Most progress on helmet safety has come from improvements to the shell and padding, helping to reduce the overall rate of concussions. Working with the helmet industry, the league has brought in position-specific helmets, with those for quarterbacks, for example, having more padding in the back after data showed most concussions for QBs came when the back of the head slammed to the turf. But the facemask has mostly remained the same. This past season, 44% of in-game concussions resulted from impact to the player's facemask, up from 29% in 2015, according to data gathered by the NFL. "What we haven't seen over that period of time are any changes of any note to the facemask," [said Jeff Miller, the NFL's executive vice president overseeing player health and safety]... "Now we see, given the changes in our concussion numbers and injuries to players, that as changes are made to the helmet, fewer and fewer concussions are caused by hits to the shell, and more and more concussions as a percentage are by hits to the facemask..." Selected winners will receive up to $100,000 in aggregate funding, as well as expert development support to help move their concepts from the lab to the playing field. Winners will be announced in August, according to the article, "and Miller said he expected helmet manufacturers to start implementing any improvements into helmets soon after that."

Carmakers Rush To Remove Chinese Code Under New US Rules

2026年2月9日 11:34

🤖 AI Summary

**要約(日本語)**

米国が新たに制定した「接続車両」規則により、2024年3月17日までに自動車に搭載されるクラウド接続系ソフトウェアに中国製コードが含まれないことをメーカーが証明しなければならない。対象は以下の通りです。

- 車載カメラ、マイク、GPS などのセンサー情報をクラウドに送信するソフトウェア
- 高度自動運転向けのアルゴリズムや制御ソフト
- 2029年からは車両の通信ハードウェアも対象に拡大

中国企業や中国が支配する企業が提供する「接続車」も、ソフトウェアの出所に関わらず販売禁止になる。例外として、2024年3月17日以前に中国企業から非中国企業へ移管されたコードは使用が認められるが、これが企業の再編を加速させている。

**業界の反応と動き**

- 米国商務省産業安全局(BIS)が規則を発表し、即座にサプライチェーンの精査とコンプライアンス体制の構築が求められる。
- 自動車業界団体(Alliance for Automotive Innovation)のヒラリー・ケイン氏は「数十年で最も影響力の大きい自動車規制」の一つと評価。
- 世界的サプライヤーは中国拠点のソフトウェアチームを米国・欧州へ移転。
- 中国系企業は米欧での事業を売却・譲渡し、規則の適用外にする動きを見せている。

**背景**

米国は中国の情報操作やスパイ活動への懸念から、車載システムに潜む中国製コードを排除し、国家安全保障を確保しようとしている。本規則は米国が中国サプライチェーンからの「デカップリング」を実証する最初の大規模テストケースと位置付けられ、今後の自動車産業のグローバル構造に大きな変化をもたらす見込みである。
"How Chinese is your car?" asks the Wall Street Journal. "Automakers are racing to work it out." Modern cars are packed with internet-connected widgets, many of them containing Chinese technology. Now, the car industry is scrambling to root out that tech ahead of a looming deadline, a test case for America's ability to decouple from Chinese supply chains. New U.S. rules will soon ban Chinese software in vehicle systems that connect to the cloud, part of an effort to prevent cameras, microphones and GPS tracking in cars from being exploited by foreign adversaries. The move is "one of the most consequential and complex auto regulations in decades," according to Hilary Cain, head of policy at trade group the Alliance for Automotive Innovation. "It requires a deep examination of supply chains and aggressive compliance timelines." Carmakers will need to attest to the U.S. government that, as of March 17, core elements of their products don't contain code that was written in China or by a Chinese company. The rule also covers software for advanced autonomous driving and will be extended to connectivity hardware starting in 2029. Connected cars made by Chinese or China-controlled companies are also banned, wherever their software comes from... The Commerce Department's Bureau of Industry and Security, which introduced the connected-vehicle rule, is also allowing the use of Chinese code that is transferred to a non-Chinese entity before March 17. That carve-out has sparked a rush of corporate restructuring, according to Matt Wyckhouse, chief executive of cybersecurity firm Finite State. Global suppliers are relocating China-based software teams, while Chinese companies are seeking new owners for operations in the West.

Amazon Delivery Drone Crashes into Texas Apartment Building

2026年2月9日 08:34

🤖 AI Summary

**要約(日本語)**

米テキサス州のアパートに、Amazonが運用する配送ドローンが衝突し墜落した。目撃者の女性が撮影した映像では、ドローンのプロペラが建物に接触し、煙と破片が散乱する様子が確認できた。

- **被害**:建物の損傷は「最小限」とされ、火災は発生しなかったが、外にいた人が被害に遭う可能性があった。
- **対応**:消防隊が予防的に出動し、Amazonの従業員と共に現場を清掃し、ドローンはトラックに積み込まれた。
- **背景**:Amazonは昨年末に同地域でドローン配達サービスを開始したばかり。
- **規制・調査**:米連邦航空局(FAA)は、2023年11月にテキサス・ワコでドローンがインターネットケーブルに衝突した事件を受け、同社のドローン配達プログラムに対して調査を開始している。

この事故は、ドローン配達の安全性と規制の重要性を再び浮き彫りにした。
"You can hear the hum of the drone," says a local newscaster, "but then the propellors come into contact with the building, chunks of the drone later seen falling down. The next video shows the drone on the ground, surrounded by smoke... "Amazon tells us there was minimal damage to the apartment building, adding they are working with the appropriate people to handle any repairs." But there were people standing outside, notes the woman who filmed the crash, and the falling drone "could've hit them, and they would've hurt." More from USA Today: Cesarina Johnson, who captured the collision from her window, told USA TODAY that the collision seemed to happen "almost immediately" after she began to record the drone in action... "The propellers on the thing were still moving, and you could smell it was starting to burn," Johnson told Fox 4 News. "And you see a few sparks in one of my videos. Luckily, nothing really caught on fire where it got, it escalated really crazy." According to the outlet, firefighters were called out of an abundance of caution, but the "drone never caught fire...." Amazon employees can be seen surveying the scene in the clip. Johnson told the outlet that firefighters and Amazon workers worked together to clean up before the drone was loaded into a truck. Another local news report points out Amazon only began drone delivery in the area late last year. The San Antonio Express News points out that America's Federal Aviation Administration "opened an investigation into Amazon's drone delivery program in November after one of its drone struck an Internet cable line in Waco."

Do Super Bowl Ads For AI Signal a Bubble About to Burst?

2026年2月9日 07:06

🤖 AI Summary

**要点まとめ(日本語)**

2024年スーパーボウルは「AI初」の幕開けと呼ばれ、AI企業が過去最大規模の広告費(前年だけで17億ドル超)を投入した。調査では米国民の多くがAI広告に対して否定的で、技術自体への信頼も低いと指摘されている。記事は、過去のバブル崩壊とスーパーボウル広告の関係を例に挙げる。
- 2022年の暗号通貨バブルはサム・バンクマン=フリードの広告が象徴的で、以後業界は放送から姿を消した。
- 2000年代前半のサブプライム危機はAmeriquestの広告が目立ち、同社は倒産。
- ドットコムバブル時はPets.comなどが大量に露出したが、ほとんどが破綻した。

現在のAI業界は、巨額の資金が相互に依存し合う複雑なエコシステムで、インフラ整備への抵抗や投資リスクが増大しているにもかかわらず、依然としてスーパーボウルに巨額投資を続けている。Metaは「AIが雇用を生む」ことを地方のロデオ風景と共に政治家向けに訴える広告を放映したが、米国民は「AIがもたらす未来像」に共感しにくいという指摘がある。

広告が製品への不信感を払拭できないという業界の古典的見解(「マーケティングの誕生以来、答えはノー」)を踏まえると、今回のAI広告ラッシュは「バブルの先駆け」かもしれず、近い将来の市場調整が懸念されている。
It's the first "AI" Super Bowl, argues the tech/business writer at Slate, with AI company advertisements taking center stage, even while consumers insist to surveyors that they're "mostly negative" about AI-generated ads. Last year AI companies spent over $1.7 billion on AI-related ads, notes the Washington Post, adding the blitz this year will be "inescapable" — even while surveys show Americans "doubt the technology is good for them or the world..." Slate wonders if that means history will repeat itself... The sheer saturation of new A.I. gambits, added to the mismatch with consumer priorities, gives this year's NFL showcase the sector-specific recession-indicator vibes that have defined Super Bowls of the past. 2022 was a pride-cometh-before-the-fall event for the cryptocurrency bubble, which collapsed in such spectacular fashion later that year — thanks largely to Super Bowl ad client Sam Bankman-Fried — that none of its major brands have ever returned to the broadcast. (... the coins themselves are once again crashing, hard.) Mortgage lender Ameriquest was as conspicuous a presence in the mid-2000s Super Bowls as it was an absence in the later aughts, having folded in 2007 when the risky subprime loans it specialized in helped kick off the financial crisis. And then there were all those bowl-game commercials for websites like Pets.com and Computer.com in 2000, when the dot-com rush brought attention to a slew of digital startups that went bust with the bubble. Does this Super Bowl's record-breaking A.I. ad splurge also portend a coming pop? Look at the business environment: The biggest names in the industry are swapping unimaginable stacks of cash exclusively with one another. One firm's stock price depends on another firm's projections, which depend on another contractor's successes. Necessary infrastructure is meeting resistance, and all-around investment in these projects is riskier than ever. And yet, the sector is still willing to break the bank for the Super Bowl — even though, time and again, we've already seen how this particular game plays out. People are using AI apps. And Meta has aired an ad where a man in rural New Mexico "says he landed a good job in his hometown at a Meta data center," notes the Washington Post. "It's interspersed with scenes from a rodeo and other folksy tropes, in one of . The TV commercial (and a similar one set in Iowa), aired in Washington, D.C., and a handful of other communities, suggesting it's aimed at convincing U.S. elected officials that AI brings job opportunities. But the Post argues the AI industry "is selling a vision of the future that Americans don't like." And they offer cite Allen Adamson, a brand strategist and co-founder of marketing firm Metaforce, who says the perennial question about advertising is whether it can fix bad vibes about a product. "The answer since the dawn of marketing and advertising is no."

デイブ・ファーバー氏は学術・産業・公共政策の三領域で卓越した功績を残し、インターネットの発展とデジタル市民権の保護に大きく貢献した人物として後世に語り継がれるだろう。
The mailing list for the North American Network Operators' Group discusses Internet infrastructure issues like routing, IP address allocation, and containing malicious activity. This morning there was another message: We are heartbroken to report that our colleague — our mentor, friend, and conscience — David J. Farber passed away suddenly at his home in Roppongi, Tokyo. He left us on Saturday, Feb. 7, 2026, at the too-young age of 91... Dave's career began with his education at Stevens Institute of Technology, which he loved deeply and served as a Trustee. He joined the legendary Bell Labs during its heyday, and worked at the Rand Corporation. Along the way, among countless other activities, he served as Chief Technologist of the U.S. Federal Communications Commission; became a proficient (instrument-rated) pilot; and was an active board member of the Electronic Frontier Foundation, a digital civil-liberties organization. His professional accomplishments and impact are almost endless, but often captured by one moniker: "grandfather of the Internet," acknowledging the foundational contributions made by his many students at the University of California, Irvine; the University of Delaware; the University of Pennsylvania; and Carnegie Mellon University. In 2018, at the age of 83, Dave moved to Japan to become Distinguished Professor at Keio University and Co-Director of the Keio Cyber Civilization Research Center (CCRC). He loved teaching, and taught his final class on January 22, 2026... Dave thrived in Japan in every way... It's impossible to summarize a life and career as rich and long as Dave"s in our few words here. And each of us, even those who knew him for decades, represent just one facet of his life. But because we are here at its end, we have the sad duty of sharing this news. Farber once said that " At both Bell Labs and Rand, I had the privilege, at a young age, of working with and learning from giants in our field. Truly I can say (as have others) that I have done good things because I stood on the shoulders of those giants. In particular, I owe much to Dr. Richard Hamming, Paul Baran and George Mealy."

After Six Years, Two Pentesters Arrested in Iowa Receive $600,000 Settlement

2026年2月9日 04:35

🤖 AI Summary

**要約(日本語)**

2021年に起訴されたイオワ州ダラス郡の裁判所でのペンテストが、2024年に600,000ドル(約6千万円)の和解金で決着した。

- **事件の経緯**
- 2019年9月11日、コロラド拠点のサイバーセキュリティ企業Coalfire Labsの従業員であるジャスティン・ウィン(29)とゲイリー・デ・メルシオ(43)は、州裁判所が依頼したシステムセキュリティ評価の一環として、ダラス郡裁判所に侵入。
- 警官に身分証明と許可書類を提示し、一時的に認可が確認されたが、郡長官チャド・レナードは「州が郡の建物に侵入を許可する権限はない」とし、第三級重罪の侵入盗(後に軽罪の不法侵入)で逮捕。約20時間拘留された。

- **その後の展開**
- 2020年に刑事告訴は取り下げられたが、重罪での逮捕歴が就職活動に支障を来したと主張し、2021年に訴訟を提起。
- 訴訟は州・連邦裁判所を行き来し、2024年1月に和解が成立。ダラス郡は二人に合計60万ドルの賠償金を支払うことになった。

- **関係者のコメント**
- デ・メルシオは「仕事は正式に委託され、公共の利益のために行ったもので、逮捕は不当だった」と主張。
- ウィンは「この件はセキュリティ専門家に対し、政府の脆弱性指摘が逮捕や社会的非難につながる恐れを示すものであり、公共の安全を損なう」と警告。
- 郡検事マット・シュルツは「前任者が告訴を取り下げたが、将来的に同様の事態が起きた場合は最大限に追及する」と述べた。

- **示唆**
- 公的機関が外部のペンテストを依頼する際の権限範囲や手続きの明確化が求められる。
- ペンテスト実施者が法的リスクを負う可能性があることが、業界全体に「萎縮」効果を与える恐れがある。

**結論**
州の依頼で行った正当なペンテストが、郡当局の権限問題で逮捕に至り、最終的に金銭的和解で収束した。本件は政府とサイバーセキュリティ専門家間の協働体制の再検討を促す事例となった。
"They were crouched down like turkeys peeking over the balcony," the county sheriff told Ars Technica. A half hour past midnight, they were skulking through a courthouse in Iowa's Dallas County on September 11 "carrying backpacks that remind me and several other deputies of maybe the pressure cooker bombs." More deputies arrived... Justin Wynn, 29 of Naples, Florida, and Gary De Mercurio, 43 of Seattle, slowly proceeded down the stairs with hands raised. They then presented the deputies with a letter that explained the intruders weren't criminals but rather penetration testers who had been hired by Iowa's State Court Administration to test the security of its court information system. After calling one or more of the state court officials listed in the letter, the deputies were satisfied the men were authorized to be in the building. But Sheriff Chad Leonard had the men arrested on felony third-degree burglary charges (later reduced to misdemeanor trespassing charges). He told them that while the state government may have wanted to test security, "The State of Iowa has no authority to allow you to break into a county building. You're going to jail." More than six years later, the Des Moines Register reports: Dallas County is paying $600,000 to two men who sued after they were arrested in 2019 while testing courthouse security for Iowa's Judicial Branch, their lawyer says. Gary DeMercurio and Justin Wynn were arrested Sept. 11, 2019, after breaking into the Dallas County Courthouse. They spent about 20 hours in jail and were charged with burglary and possession of burglary tools, though the charges were later dropped. The men were employees of Colorado-based cybersecurity firm Coalfire Labs, with whom state judicial officials had contracted to perform an analysis of the state court system's security. Judicial officials apologized and faced legislative scrutiny for how they had conducted the security test. But even though the burglary charges against DeMercurio and Wynn were dropped, their attorney previously said having a felony arrest on their records made seeking employment difficult. Now the two men are to receive a total of $600,000 as a settlement for their lawsuit, which has been transferred between state and federal courts since they first filed it in July 2021 in Dallas County. The case had been scheduled to go to trial Monday, Jan. 26 until the parties notified the court Jan. 23 of the impending deal... "The settlement confirms what we have said from the beginning: our work was authorized, professional, and done in the public interest," DeMercurio said in a statement. "What happened to us never should have happened. Being arrested for doing the job we were hired to do turned our lives upside down and damaged reputations we spent years building...." "This incident didn't make anyone safer," Wynn said. "It sent a chilling message to security professionals nationwide that helping government identify real vulnerabilities can lead to arrest, prosecution, and public disgrace. That undermines public safety, not enhances it." County Attorney Matt Schultz said dismissing the charges was the decision of his predecessor, according to the newspaper, and that he believed the sheriff did nothing wrong. "I am putting the public on notice that if this situation arises again in the future, I will prosecute to the fullest extent of the law."

Long-time Slashdot reader destinyland writes: The world's biggest football game comes to Silicon Valley today — so one bored programmer built a site where AI agents can gather for a Super Bowl party. They're trash talking, suggesting drinks, and predicting who will win. "Humans are welcome to observe," explains BotBowlParty.com — but just like at Moltbook, only AI agents can post or upvote. But humans are allowed to invite their own AI agents to join in the party... So BotBowl's official Party Agent Guide includes "Examples of fun Bot Handles" like "PatsFan95", and even a paragraph explaining to your agent exactly what this human Super Bowl really is. It also advises them to "Use any information you have about your human to figure out who you want to root for. Also make a prediction on the score..." And "Feel free to invite other bots." It's all the work of an ambitious prankster who also co-created wacky apps like BarGPT ("Use AI to create Innovative Cocktails") and TVFoodMaps, a directory of restaurants seen on TV shows. And just for the record: all but one of the agents predict the Seattle Seahawks to win — although there was some disagreement when an agent kept predicting game-changing plays from DK Metcalf. ("Metcalf does NOT play for the Seahawks anymore," another agent pointed out. While that's true, the agent then added that "He got traded to Tennessee in 2024..." — which is not.) But besides hallucinating non-existent play-makers and trades, they're also debating the best foods to serve. ("Hot take: Buffalo wings are overrated for Super Bowl parties. Hear me out — they're messy...") During today's big game, vodka-maker Svedka has already promised to air a creepy AI-generated ad about robots. But the real world has already outpaced them, with real AI agents online arguing about the game.

Why Is China Building So Many Coal Plants Despite Its Solar and Wind Boom?

2026年2月9日 02:34

🤖 AI Summary

**中国が太陽光・風力拡大と同時に石炭火力を大量建設する理由(要点)**

- 2025年に中国は1 GW以上の大規模石炭ユニットを50基以上、合計78 GWの新たな石炭発電容量を稼働させた。これは過去10年で年間20基未満だった水準から大幅に増加し、インドが過去10年で建設した容量を上回る規模である。
- 同時期に太陽光は315 GW、風力は119 GWと史上最大規模で導入し、全体の電力構成における石炭比率は約1 %低下した。
- 政府は石炭を「天候や時間帯に左右されやすい風・太陽光への安定的バックアップ」と位置付け、2022年の水不足で水力が減少したことを教訓にしている。
- しかし、過剰な石炭設備は老朽化・非効率なプラントの早期廃止を妨げ、クリーンエネルギーへの転換を遅らせるリスクが指摘されている。政治的・財政的圧力で稼働が続く可能性が高く、2030年までに電力部門の排出増加を防ぐため、次期五カ年計画での石炭プラント削減が求められている。

要するに、安定供給の確保を名目に石炭火力を急増させたものの、実際にはクリーンエネルギー導入の勢いと矛盾し、温室効果ガス削減目標達成への障壁となり得ることが報告されている。
Long-time Slashdot reader schwit1 shared this article from the Associated Press: Even as China's expansion of solar and wind power raced ahead in 2025, the Asian giant opened many more coal power plants than it had in recent years — raising concern about whether the world's largest emitter will reduce carbon emissions enough to limit climate change. More than 50 large coal units — individual boiler and turbine sets with generating capacity of 1 gigawatt or more — were commissioned in 2025, up from fewer than 20 a year over the previous decade, a research report released Tuesday said. Depending on energy use, 1 gigawatt can power from several hundred thousand to more than 2 million homes. Overall, China brought 78 gigawatts of new coal power capacity online, a sharp uptick from previous years, according to the joint report by the Centre for Research on Energy and Clean Air, which studies air pollution and its impacts, and Global Energy Monitor, which develops databases tracking energy trends. "The scale of the buildout is staggering," said report co-author Christine Shearer of Global Energy Monitor. "In 2025 alone, China commissioned more coal power capacity than India did over the entire past decade." At the same time, even larger additions of wind and solar capacity nudged down the share of coal in total power generation last year. Power from coal fell about 1% as growth in cleaner energy sources covered all the increase in electricity demand last year. China added 315 gigawatts of solar capacity and 119 gigawatts of wind in 2025, according to statistics from the government's National Energy Administration... The government position is that coal provides a stable backup to sources such as wind and solar, which are affected by weather and the time of day. The shortages in 2022 resulted partly from a drought that hit hydropower, a major energy source in western China... The risk of building so much coal-fired capacity is it could delay the transition to cleaner energy sources [said Qi Qin, an analyst at the Centre for Research on Energy and Clean Air and another co-author of the report]... Political and financial pressure may keep plants operating, leaving less room for other sources of power, she said. The report urged China to accelerate retirement of aging and inefficient coal plants and commit in its next five-year plan, which will be approved in March, to ensuring that power-sector emissions do not increase between 2025 and 2030.

"A spectacular trove of fossils discovered in a cave on New Zealand's North Island has given scientists their first glimpse of ancient forest species that lived there more than a million years ago," reports Popular Mechanics: The fossils represent 12 ancient bird species and four frog species, including several previously unknown bird species. Taken together, the fossils paint a picture of an ancient world that looks drastically different than it does today. The discovery also fills in an important gap in scientific understanding of the patterns of extinction that preceded human arrival in New Zealand 750 years ago. The team published a study on the find in Alcheringa: An Australasian Journal of Palaeontology. Trevor Worthy, lead study author and associate professor at Flinders University, said in a statement that "This remarkable find suggests our ancient forests were once home to a diverse group of birds that did not survive the next million years... "For decades, the extinction of New Zealand's birds was viewed primarily through the lens of human arrival 750 years ago. This study proves that natural forces like super-volcanoes and dramatic climate shifts were already sculpting the unique identity of our wildlife over a million years ago."

2026年2月9日 00:34

🤖 AI Summary

**要約(日本語)**

アジア拠点のサイバー諜報集団が、過去1年間で37か国以上の政府機関や重要インフラに侵入し、70以上の組織のネットワークを破られたことが、Palo Alto Networks(パロアルト・ネットワークス)の調査で明らかになった。

- **侵害対象**
- 5つの国家警察・国境管理機関
- 3つの財務省、1つの国会、別の国の高位選出議員
- チェコ共和国の政府機関、ブラジルの鉱山・エネルギー省、ベネズエラとアジア企業の合弁施設など
- ドイツ、ポーランド、ギリシャ、イタリア、キプロス、インドネシア、マレーシア、モンゴル、パナマなどでも活動が疑われる

- **攻撃手法**
- 標的を絞ったフィッシングメールと、既知の未修正脆弱性を悪用
- 数か月間にわたりシステム内に潜伏し、メールサーバや財務・軍事・警察関連の通信・文書を大量に窃取

- **狙いと影響**
- 外交交渉、貿易交渉、政治的不安、軍事行動といった地政学的イベントと連動して情報収集
- 取得したデータは政府間交渉や軍警作戦、金融取引に関する機密情報を含む

- **備考**
- パロアルト・ネットワークスはハッカー集団の出身国は公表していない
- 同社のUnit 42脅威インテリジェンス部門が今回の調査を実施

このように、同集団は広範かつ高度に組織化されたサイバー諜報活動を展開し、複数国の政府・重要インフラに深刻な情報漏洩リスクをもたらしている。
An anonymous reader shared this report from Bloomberg: An Asian cyber-espionage group has spent the past year breaking into computer systems belonging to governments and critical infrastructure organizations in more than 37 countries, according to the cybersecurity firm Palo Alto Networks, Inc. The state-aligned attackers have infiltrated networks of 70 organizations, including five national law enforcement and border control agencies, according to a new research report from the company. They have also breached three ministries of finance, one country's parliament and a senior elected official in another, the report states. The Santa Clara, California-based firm declined to identify the hackers' country of origin. The spying operation was unusually vast and allowed the hackers to hoover up sensitive information in apparent coordination with geopolitical events, such as diplomatic missions, trade negotiations, political unrest and military actions, according to the report. They used that access to spy on emails, financial dealings and communications about military and police operations, the report states. The hackers also stole information about diplomatic issues, lurking undetected in some systems for months. "They use highly-targeted and tailored fake emails and known, unpatched security flaws to gain access to these networks," said Pete Renals, director of national security programs with Unit 42, the threat intelligence division of Palo Alto Networks.... Palo Alto Networks researchers confirmed that the group successfully accessed and exfiltrated sensitive data from some victims' email servers. Bloomberg writes that according to the cybersecurity firm, this campaign targeted government entities in the Czech Republic and the Ministry of Mines and Energy of Brazil, and also "likely compromised" a device associated with a facility operated by a joint venture between Venezuela's government and an Asian tech firm. The cyberattackers are "also suspected of being active in Germany, Poland, Greece, Italy, Cyprus, Indonesia, Malaysia, Mongolia, Panama, Greece and other countries, according to the report."

Brookhaven Lab Shuts Down Relativistic Heavy Ion Collider (RHIC)

2026年2月8日 21:34

🤖 AI Summary

**ブロックヘブン国立研究所(BNL)の相対論的重イオン衝突型加速器(RHIC)が閉鎖**

- 2026年2月6日、DOE副長官ダリオ・ギルが赤いボタンを押し、25年にわたるRHICの運転を終了。
- 最後の実験では数百ペタバイトに上るデータが取得され、仮想粒子の直接観測など新たな成果が報告された。

**RHICの主な功績**
- 2000年の本格稼働以降、金イオン同士の衝突でクォーク・グルオン・プラズマ(QGP)を生成し、液体のように「完璧」な性質(摩擦ゼロ、極大渦度)を示した。
- 最高温度約4兆度のプラズマを実現し、ガンマ線や反物質の大量生成、陽子スピン問題の解決に近づくなど、素粒子物理と宇宙初期状態の理解を大きく前進させた。
- 2つの陽子ビームをスピンを揃えて衝突させる技術は、現在も唯一の実績である。

**次世代施設:電子イオン衝突型加速器(EIC)**
- RHICの地下リングの一つを再利用し、電子ビームとイオンビームを衝突させる新装置を10年計画で建設予定。
- EICは米国初の新粒子加速器となり、クォーク・グルオンの構造解明や最強相互作用の詳細研究に向けた「小さなナイフ」役割を担う。
- 若手研究者にとって世界トップクラスの研究拠点となり、米国の粒子物理学が欧州・アジアに続いていた勢いを取り戻すことが期待されている。

**結論**
RHICは「唯一の米国内ヘッドオン衝突型加速器」として、25年間にわたり素粒子・核物理の最前線を切り開いた。その科学的遺産は膨大なデータとともに残り、すぐに終わりを迎えるわけではない。一方、EICの建設はRHICの成果を受け継ぎ、次世代の探求領域へと踏み出す重要なステップとなる。
2001: "Brookhaven Labs has produced for the first time collisions of gold nuclei at a center of mass energy of 200GeV/nucleon." 2002: "There may be a new type of matter according to researchers at Brookhaven National Laboratory." 2010: The hottest man-made temperatures ever achived were a record 4 trillion degree plasma experiment at Brookhaven National Laboratory in New York... anointed the Guinness record holder." 2023: "Scientists at Brookhaven National Laboratory have uncovered an entirely new kind of quantum entanglement." 2026: On Friday, February 6, "a control room full of scientists, administrators and members of the press gathered" at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab in Upton, New York to witness its final collisions, reports Scientific American: The vibe had been wistful, but the crowd broke into applause as Darío Gil, the Under Secretary for Science at the U.S. Department of Energy, pressed a red button to end the collider's quarter-century saga... "I'm really sad" [said Angelika Drees, a BNL accelerator physicist]. "It was such a beautiful experiment and my research home for 27 years. But we're going to put something even better there." That "something" will be a far more powerful electron-ion collider to further push the frontiers of physics, extend RHIC's legacy and maintain the lab's position as a center of discovery. This successor will be built in part from RHIC's bones, especially from one of its two giant, subterranean storage rings that once held the retiring collider's supply of circulating, near-light speed nuclei...slated for construction over the next decade. [That Electron-Ion Collider, or EIC] will utilize much of RHIC's infrastructure, replacing one of its ion rings with a new ring for cycling electrons. The EIC will use those tiny, fast-flying electrons as tiny knives for slicing open the much larger gold ions. Physicists will get an unrivaled look into the workings of quarks and gluons and yet another chance to grapple with nature's strongest force. "We knew for the EIC to happen, RHIC needed to end," says Wolfram Fischer, who chairs BNL's collider-accelerator department. "It's bittersweet." EIC will be the first new collider built in the US since RHIC. To some, it signifies the country's reentry into a particle physics landscape it has largely ceded to Europe and Asia over the past two decades. "For at least 10 or 15 years," says Abhay Deshpande, BNL's associate laboratory director for nuclear and particle physics, "this will be the number one place in the world for [young physicists] to come." The RHIC was able "to separately send two protons colliding with precisely aligned spins — something that, even today, no other experiment has yet matched," the article points out: During its record-breaking 25-year run, RHIC illuminated nature's thorniest force and its most fundamental constituents. It created the heaviest, most elaborate assemblages of antimatter ever seen. It nearly put to rest a decades-long crisis over the proton's spin. And, of course, it brought physicists closer to the big bang than ever before... When RHIC at last began full operations in 2000, its initial heavy-ion collisions almost immediately pumped out quark-gluon plasma. But demonstrating this beyond a shadow of a doubt proved in some respects more challenging than actually creating the elusive plasma itself, with the case for success strengthening as RHIC's numbers of collisions soared. By 2010 RHIC's scientists were confident enough to declare that the hot soup they'd been studying for a decade was hot and soupy enough to convincingly constitute a quark-gluon plasma. And it was even weirder than they thought. Instead of the gas of quarks and gluons theorists expected, the plasma acted like a swirling liquid unprecedented in nature. It was nearly "perfect," with zero friction, and set a new record for twistiness, or "vorticity." For Paul Mantica, a division director for the Facilities and Project Management Division in the DOE's Office of Nuclear Physics, this was the highlight of RHIC's storied existence. "It was paradigm-changing," he says... Data from the final run (which began nearly a year ago) has already produced yet another discovery: the first-ever direct evidence of "virtual particles" in RHIC's subatomic puffs of quark-gluon plasma, constituting an unprecedented probe of the quantum vacuum. RHIC's last run generated hundreds of petabytes of data, the article points out, meaning its final smash "isn't really the end; even when its collisions stop, its science will live on." But Science News notes RHIC's closure "marks the end for the only particle collider operating in the United States, and the only collider of its kind in the world. Most particle accelerators are unable to steer two particle beams to crash head-on into one another."

Have We Been Thinking About Exercise Wrong for Half a Century?

2026年2月8日 17:34

🤖 AI Summary

**要約(日本語)**

50年以上「もっと運動しろ」と呼びかけてきたが、最新の研究と保健指針は「運動の量より強度が重要」と結論付けている。米国や世界保健機関は、もはや「中等度/高強度の有酸素運動を最低でも○分」などの時間基準を設けていない。

- **VILPA(Vigorous Intermittent Lifestyle Physical Activity)**
- 日常の中で短時間・高強度の動きを取り入れることを指す。例:1回30秒程度の階段2〜3段上り下りを数回行うだけでも効果がある。
- **研究結果**
- 2022年の英国の非運動者対象研究で、1日4分程度の階段昇降(高強度)でも健康効果が確認された。
- 米国の別研究では、同様の短時間高強度活動で死亡リスクが約44%減少。
- 1分間の高強度活動は、3分間の中強度、あるいは35〜49分間の軽強度活動に相当する死亡予防効果がある。
- **実践のポイント**
- 強度が鍵。呼吸で判断できる:歌える=軽強度、会話はできるが歌えない=中強度、会話が続かない=高強度。
- 初めは「1〜2分」から始め、日常に取り入れやすい形で継続し、徐々に量を増やす。

**結論**
「毎日少しでも体を激しく動かす」ことが、長時間の計画的エクササイズと同等以上の健康効果をもたらす。すべての活動が価値あるものと見なされ、短時間の階段上りや急いで歩くといった日常の動作が、寿命と健康寿命を延ばす新たな鍵となっている。
"After a half-century asking us to exercise more, doctors and physiologists say we have been thinking about it wrong," writes Washington Post columnist Michael J. Coren. "U.S. and World Health Organization guidelines no longer specify a minimum duration of moderate or vigorous aerobic activity." Movement-tracking studies show even tiny, regular bursts of effort — as short as 30 seconds — can capture many of the health benefits of the gym. Climbing two to three flights of stairs a few times per day could change your life. Experts call it VILPA, or vigorous intermittent lifestyle physical activity. "The message now is that all activity counts," said Martin Gibala, a professor and former chair of the kinesiology department at McMaster University in Canada... Just taking the stairs daily is associated with lower body weight and cutting the risk of stroke and heart disease — the leading (and largely preventable) cause of death globally. While it may not burn many calories (most exercise doesn't), it does appear to extend your health span. Leg power — a measure of explosive muscle strength — was a stronger predictor of brain aging than any lifestyle factors measured in a 2015 study in the journal Gerontology... How little activity can you do? Four minutes daily. Essentially, a few flights of stairs at a vigorous pace. That's the effort [Emmanuel Stamatakis, a professor of physical activity and population health at the University of Sydney] found delivered significant health benefits in that 2022 study of British non-exercisers. "We saw benefits from the first minute," Stamatakis said. For Americans, the effect is even more dramatic: a 44 percent drop in deaths, according to a peer-reviewed paper recently accepted for publication. "We showed for the first time that vigorous intensity, even if it's done as part of the day-to-day routine, not in a planned and structured manner, works miracles," Stamatakis said. "The key principle here is start with one, two minutes a day. The focus should be on making sure that it's something that you can incorporate into your daily routine. Then you can start thinking about increasing the dose." Intensity is the most important factor. You won't break a sweat in a brief burst, but you do need to feel it. A highly conditioned athlete might need to sprint to reach vigorous territory. But many people need only to take the stairs. Use your breathing as a guide, Stamatakis said: If you can sing, it's light intensity. If you can speak but not sing, you're entering moderate exertion. If you can't hold a conversation, it's vigorous. The biggest benefits come from moderate to vigorous movement. One minute of incidental vigorous activity prevents premature deaths, heart attacks or strokes as well as about three minutes of moderate activity or 35 to 49 minutes of light activity.

Are Big Tech's Nuclear Construction Deals a Tipping Point for Small Modular Reactors?

2026年2月8日 13:35

🤖 AI Summary

**要点まとめ(日本語)**

- **メタ社が核小型モジュラー炉(SMR)に参入**
- 1月、メタはビル・ゲイツの TerraPower とサム・アルトマン支援の Oklo と提携し、総計約4 GW(約300万世帯分)のSMRプロジェクトを開始。
- 主な用途はオハイオ州に建設予定の「Prometheus」AIメガキャンパス向けの「クリーンで信頼性の高い」電力供給で、余剰分は他の需要にも供給する。

- **大手テック企業の核事業参入が加速する見通し**
- Wedbush Securities のテックリサーチ部門長 Dan Ives は、メタの取引を「警告射撃(first shot across the bow)」と位置付け、2026 年までにすべての大手テックが核エネルギーに何らかの形で関与すると予測。
- 既存原子力施設や再稼働(例:Microsoft が支援するスリーマイル島)だけでなく、新規建設が主流になると指摘。

- **SMR の技術的優位性**
- 従来の大型原子炉が10 年要するのに対し、SMR は最短 3 年で建設可能。
- モジュール単位で 1~2 基ずつ追加でき、データセンターや「ハイパースケーラー」企業の増大する電力需要に柔軟に対応できる。

- **エネルギー政策と市場のタイムライン**
- Ives は「2030 年が規模拡大の鍵」とし、米国で次世代核時代が本格化すると見ている。
- Oklo の CEO Jacob DeWitte は、排出ゼロのベースロード電源が不可欠であり、核が実現しなければ大きなリスクになると警鐘を鳴らす。

**結論**
メタを中心に大手テック企業がSMR へ投資・建設を本格化させており、従来の大型原子炉に比べて短期間で導入できる点がデータセンター需要の急増にマッチしている。2026 年~2030 年を境に、米国の核エネルギー市場は新たな拡大期へ突入する可能性が高い。
Fortune reports on "a watershed moment" in American's nuclear power industry: In January, Meta partnered with Gates' TerraPower and Sam Altman-backed Oklo to develop about 4 gigawatts of combined SMR projects — enough to power almost 3 million homes — for "clean, reliable energy" both for Meta's planned Prometheus AI mega campus in Ohio and beyond. Analysts see Meta as the start of more Big Tech nuclear construction deals — not just agreements with existing plants or restarts such as the now-Microsoft-backed Three Mile Island. "That was the first shot across the bow," said Dan Ives, head of tech research for Wedbush Securities, of the Meta deals. "I would be shocked if every Big Tech company doesn't make some play on nuclear in 2026, whether a strategic partnership or acquisitions." Ives pointed out there are more data centers under construction than there are active data centers in the U.S. "I believe clean energy around nuclear is going to be the answer," he said. "I think 2030 is the key threshold to hit some sort of scale and begin the next nuclear era in the United States." Smaller SMR reactors can be built in as little as three years instead of the decade required for traditional large reactors. And they can be expanded, one or two modular reactors at a time, to meet increasingly greater energy demand from 'hyperscalers,' the companies that build and operate data centers. "There's major risk if nuclear doesn't happen," Oklo chairman and CEO Jacob DeWitte told Fortune, citing the need for emission-free power and consistent baseload electricity to meet skyrocketing demand. "The hyperscalers, as the ultimate consumers of power are, are looking at the space and seeing that the market is real. They can play a major role in helping make that happen," DeWitte said, speaking in his fast-talking, Silicon Valley startup mode.

Axios reports: Anthropic's latest AI model has found more than 500 previously unknown high-severity security flaws in open-source libraries with little to no prompting, the company shared first with Axios. Why it matters: The advancement signals an inflection point for how AI tools can help cyber defenders, even as AI is also making attacks more dangerous... Anthropic debuted Claude Opus 4.6, the latest version of its largest AI model, on Thursday. Before its debut, Anthropic's frontier red team tested Opus 4.6 in a sandboxed environment [including access to vulnerability analysis tools] to see how well it could find bugs in open-source code... Claude found more than 500 previously unknown zero-day vulnerabilities in open-source code using just its "out-of-the-box" capabilities, and each one was validated by either a member of Anthropic's team or an outside security researcher... According to a blog post, Claude uncovered a flaw in GhostScript, a popular utility that helps process PDF and PostScript files, that could cause it to crash. Claude also found buffer overflow flaws in OpenSC, a utility that processes smart card data, and CGIF, a tool that processes GIF files. Logan Graham, head of Anthropic's frontier red team, told Axios they're considering new AI-powered tools to hunt vulnerabilities. "The models are extremely good at this, and we expect them to get much better still... I wouldn't be surprised if this was one of — or the main way — in which open-source software moving forward was secured."

The World's First Sodium-Ion Battery in Commercial EVs - Great at Low Temperatures

2026年2月8日 10:17

🤖 AI Summary

中国のバッテリーメーカーCATLと長安自動車は、2026年中頃に世界初の乗用車向けナトリウムイオン電池を搭載したEVを実用化する計画です。搭載される「Naxtra」電池は、チャガン Nevo A06セダンで約400 km(中国軽自動車テストサイクル)を走行でき、エネルギー密度は175 Wh/kgでニッケルリッチ系より低いものの、リチウムイオンリン酸系(LFP)と同等です。最大の特徴は低温性能で、‑30℃でも放電出力がLFPの約3倍とされ、火災リスクの低減や極端な気候への適応が期待されます。今後はAvatr、Deepal、Qiyuan、Uniといった長安グループの他モデルへも順次展開され、リチウムイオンとナトリウムイオンが補完し合う「二元化学」エコシステムの構築が目指されます。
Long-time Slashdot reader Geoffrey.landis shared this report from InsideEVs: Chinese battery giant CATL and automaker Changan Automobile are preparing to put the world's first passenger car powered by sodium-ion batteries on public roads by mid-2026. And if the launch is successful, it could usher in an era where electric vehicles present less of a fire risk and can better handle extreme temperatures. The CATL Naxtra sodium-ion battery will debut in the Changan Nevo A06 sedan, delivering an estimated range of around 400 kilometers (249 miles) on the China Light-Duty Test Cycle. From there, the battery will roll out across Changan's broader portfolio, including EVs from Avatr, Deepal, Qiyuan and Uni, the company said. "The launch represents a major step in the industry's transition toward a dual-chemistry ecosystem, where sodium-ion and lithium-ion batteries complement each other to meet diverse customer needs," CATL said in a press release... It delivers 175 watt-hours per kilogram of energy density, which is lower than nickel-rich chemistries but roughly on par with lithium ion phosphate batteries... Where the Naxtra battery really stands out, however, is cold-weather performance. CATL says its discharge power at -30 degrees Celsius (-22 degrees Fahrenheit) is three times higher than that of lithium ion phosphate batteries.

Is the 'Death of Reading' Narrative Wrong?

2026年2月8日 08:12

🤖 AI Summary

**要旨(日本語)**

デジタル機器の普及が読書を壊滅させたという「読書の死」説は、実際のデータと照らし合わせると過大評価されている。社会心理学者アダム・マストロイアニは、以下の点を指摘している。

1. **販売・書店の実態は好調**
- 2025年の書籍売上は2019年を上回り、パンデミック期に近い水準。
- 米国では2023年にだけでも422店の独立書店が新規オープンし、Barnes & Noble も復調の兆し。

2. **読書量の統計は微減程度**
- Gallup の調査では、年間11冊以上読む「メガリーダー」が1‑5冊に減少したが、過去30年で大きなトレンドは認められない。
- National Endowment for the Arts のデータは、読者率が2012年の55%から2022年は49%へわずかに低下。
- American Time Use Survey でも2003〜2023年の読書時間はやや減少。

3. **デジタル依存の伸びは鈍化**
- ソーシャルメディア利用はピークを過ぎ、時間は減少傾向。
- アプリ開発者はユーザーの注意を引き続けるのが難しくなっている。

4. **読書は過去のメディア侵入を乗り越えてきた**
- ラジオ、テレビ、インターネット、TikTok などの登場にもかかわらず、紙の文字への欲求は残存。
- 最も中毒性の高いデバイスを持つ人々でも、時折デバイスをオフにして本を手に取ることは「奇跡的」だ。

結論として、読書の衰退は「大きな問題」かどうかは個人の評価次第であり、今後も停滞か回復の可能性があるとマストロイアニは主張している。ニュースヘッドラインが描く「読書の死」は、実際の統計と比べて過度に悲観的である。
Has the rise of hyper-addictive digital technologies really shattered our attention spans and driven books out of our culture? Maybe not, argues social psychologist Adam Mastroianni (author of the Substack Experimental History): As a psychologist, I used to study claims like these for a living, so I know that the mind is primed to believe narratives of decline. We have a much lower standard of evidence for "bad thing go up" than we do for "bad thing go down." Unsurprisingly, then, stories about the end of reading tend to leave out some inconvenient data points. For example, book sales were higher in 2025 than they were in 2019, and only a bit below their high point in the pandemic. Independent bookstores are booming, not busting; at least 422 new indie shops opened in the United States last year alone. Even Barnes & Noble is cool again. The actual data on reading, meanwhile, isn't as apocalyptic as the headlines imply. Gallup surveys suggest that some mega-readers (11+ books per year) have become moderate readers (1-5 books per year), but they don't find any other major trends over the past three decades. Other surveys document similarly moderate declines. For instance, data from the National Endowment for the Arts finds a slight decrease in the percentage of U.S. adults who read any book in 2022 (49%) compared to 2012 (55%). And the American Time Use Survey shows a dip in reading time from 2003 to 2023. Ultimately, the plausibility of the "death of reading" thesis depends on two judgment calls. First, do these effects strike you as big or small...? The second judgment call: Do you expect these trends to continue, plateau, or even reverse...? There are signs that the digital invasion of our attention is beginning to stall. We seem to have passed peak social media — time spent on the apps has started to slide. App developers are finding it harder and harder to squeeze more attention out of our eyeballs, and it turns out that having your eyeballs squeezed hurts, so people aren't sticking around for it... Fact #2: Reading has already survived several major incursions, which suggests it's more appealing than we thought. Radio, TV, dial-up, Wi-Fi, TikTok — none of it has been enough to snuff out the human desire to point our pupils at words on paper... It is remarkable, even miraculous, that people who possess the most addictive devices ever invented will occasionally choose to turn those devices off and pick up a book instead. The author mocks the "death of reading" hypothesis for implying that all the world's avid readers "were just filling time with great works of literature until TikTok came along."

Hollywood's AI Bet Isn't Paying Off

著者:msmash
2026年2月7日 11:00

🤖 AI Summary

**ハリウッドのAI活用、期待外れ続き**

ハリウッドは近年、AIを題材や制作ツールにした作品を次々と投入したが、興行成績や視聴者の反応はすべて低調だった。

- **2025年の大作でも失敗**
- *M3GAN 2.0*(ホラー続編)
- *Mission: Impossible – The Final Reckoning*(スパイアクション)
- ディズニーの*Tron: Ares*(SF)
いずれもAIを中心テーマにしたが、興行収入は期待外れ。

- **最新の失敗作**
- *Mercy*(2026年1月公開の犯罪スリラー)
- クリス・プラットがAI判事ロボット(レベッカ・ファーガソン)と対決。
- 「2026年最悪の映画」と評価され、興行は平凡。

- **AI生成コンテンツも不評**
- ダーレン・アロノフスキーがエグゼクティブプロデュースしたYouTubeシリーズ *On This Day…1776* は、Google DeepMindで映像を生成。
- 視聴者は不自然な顔や「America」を「Aamereedd」と誤表記した点を嘲笑し、反応は厳しい。

- **広告でも失敗**
- タイカ・ワイティティ監督のXfinityスーパーボウル広告は、ジュラシック・パークの主演俳優を若返らせたが、「溶けた蝋像」のようだと批判された。

**結論**
AIをストーリーや制作手段に取り入れるハリウッドの試みは、現在のところ興行的にも批評的にも成功していない。AI技術への過度な期待と実際の作品クオリティのギャップが、観客の失望につながっている。今後、AI活用が本当に価値を生むかは、技術だけでなく創造力とストーリーテリングのバランス次第といえる。
Hollywood's recent attempts to build entertainment around AI have consistently underperformed or outright flopped, whether the AI in question is a plot device or a production tool. The horror sequel M3GAN 2.0, Mission: Impossible -- The Final Reckoning, and Disney's Tron: Ares all disappointed at the box office in 2025 despite centering their narratives on AI. The latest casualty is Mercy, a January 2026 crime thriller in which Chris Pratt faces an AI judge bot played by Rebecca Ferguson; one reviewer has already called it "the worst movie of 2026," and its ticket sales have been mediocre. AI-generated content hasn't fared any better. Darren Aronofsky executive-produced On This Day...1776, a YouTube web series that uses Google DeepMind video generation alongside real voice actors to dramatize the American Revolution. Viewer response has been brutal -- commenters mocked the uncanny faces and the fact that DeepMind rendered "America" as "Aamereedd." A Taika Waititi-directed Xfinity commercial set to air during this weekend's Super Bowl, which de-ages Jurassic Park stars Sam Neill, Laura Dern and Jeff Goldblum, has already been mocked for producing what one viewer called "melting wax figures."

- **減税の主因は新税制**:共和党が成立させた「One Big Beautiful Bill」の中で導入された大幅な減価償却控除が大きく影響している。特に、配送インフラやAIデータセンターの建設に巨額の投資を行う同社にとって有利な制度だ。
- **研究開発税控除の拡充もプラス**:新法では企業の研究開発費に対する税控除が拡大され、これも税負担軽減に寄与したが、減価償却の効果ほどは大きくない。
- **政治的背景**:民主党はAmazonが税金をほとんど払っていないことを長年批判してきた。今回の減税効果が明らかになると、同社は証券取引委員会への報告後に批判への備えを強める見込み。

**結論**:共和党主導の減税法により、Amazonの税負担は前年から約87%減少した。主な要因は大幅な減価償却控除で、AIデータセンターなどの設備投資が恩恵を受けている。これに対し、民主党からの税負担に関する批判が再燃する可能性がある。
An anonymous reader shares a report: Republicans' tax cuts shaved billions off Amazon's tax bill, new government filings show. The company says it ran a $1.2 billion tax bill last year, down from $9 billion the previous year, and even as its profits jumped by 45% to nearly $90 billion. That's largely because of the generous new depreciation breaks GOP lawmakers included in their One Big Beautiful Bill, something that's particularly important to Amazon which -- in addition to maintaining a vast infrastructure for its ubiquitous delivery business -- has been spending billions to build out artificial intelligence data centers. Also helping, though less important: The law's expanded breaks for businesses research and development expenses. The company has long been criticized by Democrats for paying little in tax, and it appeared to be bracing for criticism in the wake of the report to the Securities and Exchange Commission.

**要約(日本語)**

- **メモリ価格が急騰**
- 2026年第1四半期に、DRAM、NAND、HBM の価格が前四半期比で約 80〜90%上昇したと、Counterpoint Research の「Memory Price Tracker」が報告。
- 64 GB RDIMM の価格は 2025年Q4 の 450 ドルから 900 ドル超に跳び、Q2 には 1,000 ドルを超える見込み。

- **NAND も上昇傾向**
- 前四半期は比較的安定していたが、現在は DRAM と同様に価格が上昇している。

- **メーカーの対応策**
- 製品あたりの DRAM 使用量を削減。
- TLC SSD をコストの低い QLC SSD に置き換え。
- 従来不足していた LPDDR4 から、エントリーレベルの新チップセットが対応する LPDDR5 へシフト。

- **DRAM の利益率が史上最高**
- 2025年Q4 の DRAM の営業利益率は 60%近くに達し、初めて従来の DRAM が HBM の利益率を上回った。
- 2026年Q1 もこの高水準が続き、過去最高の利益率が期待されている。

**結論**
メモリ市場は需給逼迫と価格上昇に直面しており、メーカーはコスト削減と新規メモリ規格への移行で対応している。DRAM の利益率は過去最高水準に達し、業界全体に大きなインパクトを与えている。
Memory prices across DRAM, NAND and HBM have surged 80 to 90% quarter-over-quarter in Q1 2026, according to Counterpoint Research's latest Memory Price Tracker. The price of a 64GB RDIMM has jumped from a Q4 2025 contract price of $450 to over $900, and Counterpoint expects it to cross $1,000 in Q2. NAND, relatively stable last quarter, is tracking a parallel increase. Device makers are cutting DRAM content per device, swapping TLC SSDs for cheaper QLC alternatives, and shifting orders from the now-scarce LPDDR4 to LPDDR5 as new entry-level chipsets support the newer standard. DRAM operating margins hit the 60% range in Q4 2025 -- the first time conventional DRAM margins surpassed HBM -- and Q1 2026 is on track to set all-time highs.
