タイトル:マイクロプラスティックが地球温暖化にどのように貢献しているか

記事によると、中国の復旦大学を中心に研究された新しいNature Climate Changeの論文は、空気中のマイクロプラスチックが反射するよりも吸収する熱が多い可能性があることを示しています。特に濃色や彩色された粒子は、ブラックカーボン(化石燃料を燃やす際に生成される煙の一部)と比較して大さな暖房源ではないとしても無視できるものでもないとされています。

研究者たちは、マイクロプラスチックが大気中で地球温暖化にどれほど寄与しているかを推定し、その影響はブラックカーボンの約六分の一であると推測しました。この推定値によると、1年間の世界中のマイクロプラスティックスの排出量は200基の石炭火力発電所が同一年間稼働した場合に匹敵する据え置き効果があります。

研究者たちはまた、粒子が老いていくと吸収度がどのように変わるかも調査しました。黒や彩色された粒子は、白色の粒子よりも75倍以上の吸収度を示すことが明らかになりました。この推定値は未だに不確実性が高く、より多くの研究が必要であることも強調されています。

この論文は現在の気候モデルで考慮されていない大気中の微細な粒子による追加的な暖房効果についても更なる研究が必要であると述べています。
A new Nature Climate Change study suggests airborne microplastics -- especially darker and colored particles -- are likely contributing to atmospheric warming by absorbing more heat than they reflect. Researchers estimate the effect could be roughly one-sixth that of black carbon, though outside experts say the uncertainties remain large and more study is needed before drawing firm policy conclusions. "We can say with confidence that overall they are warming agents," said Drew Shindell, a Duke University earth science professor and co-author of the study. "To me, that's the big advance." The Washington Post reports: To undertake their study, a group led by researchers at Fudan University in China examined how different colors and sizes of microplastics interact with light across the spectrum, while combining that information with simulations of how particles get dispersed in the air across the planet. "Black, yellow, blue and red [particles] absorb sunlight much more strongly than the white particles," Yu Liu, a Fudan professor and study co-author, said in a call with reporters. In fact, the study details how black and colored particles showed "absorption levels nearly 75 times higher than pristine, non-pigmented plastics." The scientists also found that different sizes of particles absorb light at different intensities -- and that how they absorb light can change as they age. The authors estimate that microplastics suspended in the atmosphere could be contributing to global warming at about one-sixth the amount of black carbon, also known as soot, a pollutant generated largely from burning fossil fuels. If the latest estimates are right, Shindell said, microplastics might not be an enormous source of atmospheric warming, compared with massive contributors such as cars and trucks, belching industrial plants or even burping cows. "But not a trivial one, either," he said. By his calculation, the effect of one year's microplastic emissions globally is approximately equivalent to 200 coal-fired power plants running for that year. But that rough estimate does not factor the longer-term repercussions of microplastics decaying and persisting in the environment for decades to come. Whatever the exact impact, the topic deserves further study, the authors say, because current climate modeling does not account for any additional warming that these tiny particles might be causing.

>Title: 超小型氷天体プラチノに気候を発見か

>Astronomers が超小型氷天体「2002 XV93」に薄い大気の存在を検出する可能性について報告しています。国立天文台の高山耕也らが Nature Astronomy で発表した研究によると、この天体は直径約500kmで、プラチノとされる軌道上に存在し、プラトニクスの1つです。

>2002 XV93は直径300マイル(500キロメートル)程度で、現在の太陽系最小型天体と見なされています。その大気は地球の大気圧の5百万から1千万分の1と非常に薄く、プラトニクスとしては他の天体よりも遠方にあります。

>この大気はメタンや窒素、一酸化炭素が主成分と考えられています。NASAのウェブ・スペース télescope などの観測により、大気の構成を確認することが可能だと高山は述べています。

>2002 XV93はニューマークベル特有の天体であり、プラトニクスとは木星公転周期の2分の1で土星公転周期の3分の2の時間がかかります。その大気の存在は火山噴火や彗星衝突によるものと考えられています。

この報告はまだ確認が必要ですが、新たな天体探索と理解に重要な一歩を踏み出したと言えます。

"The Associated Press is reporting on a new study in Nature Astronomy suggesting that a tiny, icy world beyond Pluto harbors a thin, delicate atmosphere that may have been created by volcanic eruptions or a comet strike," writes longtime Slashdot reader fahrbot-bot. From the report: Just 300 miles (500 kilometers) or so across, this mini Pluto is thought to be the solar system's smallest object yet with a clearly detected global atmosphere bound by gravity, said lead researcher Ko Arimatsu of the National Astronomical Observatory of Japan. This so-called minor planet -- formally known as (612533) 2002 XV93 -- is considered a plutino, circling the sun twice in the time it takes Neptune to complete three solar orbits. At the time of the study, it was more than 3.4 billion miles (5.5 billion kilometers) away, farther than even Pluto, the only other object in the Kuiper Belt with an observed atmosphere. This cosmic iceball's atmosphere is believed to be 5 million to 10 million times thinner than Earth's protective atmosphere, according to the the study [...]. It's 50 to 100 times thinner than even Pluto's tenuous atmosphere. The likeliest atmospheric chemicals are methane, nitrogen or carbon monoxide, any of which could reproduce the observed dimming as the object passed before the star, according to Arimatsu. Further observations, especially by NASA's Webb Space Telescope, could verify the makeup of the atmosphere, according to Arimatsu.

🤖 AI Summary

OpenAIの共同創業者兼会長、グレッグ・ブロッカムは、エルン・ミュス克との訴訟の第5日目で証言し、自身の株価が約300億ドルであることを明かしました。彼は個人的にOpenAIに投資していないにもかかわらず、その資産価値はメリンダ・フレイシス・ゲーツと匹敵するほどです。裁判長はミュス克からブロッカムとアルトマンが「アメリカで最も嫌われている男になるだろう」と警告されたという前日訴訟文書を採用しなかったことを発表しました。

ブロッカムは、彼が自身の慈善部門に10万ドル寄付する約束を果たしていないことについて認めましたが、その理由はアルトマンによる指示待ちだったと説明しました。また、初日の証言者スタウル・ラスケット教授は、ミュス克側弁護士からの高い謝金(40時間分で5万ドル)を告白し、高額な専門家費用が一般的なものより著しく高いことを明らかにしました。

この訴訟の概要:
1. ミュス克がOpenAIの訴訟で証言を終えた(第4日目)
2. ミュス克はOpenAIがGoogleに対抗するために非営利組織として設立されたと主張し、OpenAI側と衝突した(第3日目)
3. ミュス克はOpenAIの設立目的について証言し、共同創業者のサム・アルトマンとともに裁判に臨んだ(第2日目)
4. ミュス克とアルトマンが初回開廷日に法廷に向かう(第1日目)。
OpenAI president Greg Brockman's testimony dominated the fifth day of the trial for Elon Musk's lawsuit against the AI company. Brockman took the witness stand on Monday, disclosing that his stake in OpenAI is worth nearly $30 billion, despite not personally investing money in OpenAI. The judge also declined to admit a pretrial text in which Musk allegedly warned Brockman that he and Altman would become "the most hated men in America." From a report: Brockman's disclosure would put him on the Forbes list of the world's richest people, with wealth comparable to Melinda French Gates. [...] Late Sunday, OpenAI lawyers tried to admit as evidence a text message Musk sent to Brockman two days before the trial began. According to a court filing -- which did not include the actual text exchange -- Musk sent a message to Brockman to gauge interest in settlement. When Brockman replied that both sides should drop their respective claims, Musk shot back, according to the filing, "By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be." Judge Yvonne Gonzalez Rogers, who is overseeing the trial, did not admit the text exchange as evidence. Brockman acknowledged that he had promised to personally donate $100,000 to OpenAI's charity but never did. In explaining the delay, Brockman put the onus on Altman: "I asked Sam when I should donate this, and he said he would let me know," reports Business Insider. The first witness to testify on Monday was Stuart Russell, an artificial intelligence expert who teaches computer science at the University of California, Berkeley. "The most memorable part of Russell's testimony was when he talked about how much Musk's legal team paid him," notes Business Insider. "He received an eye-popping $5,000 per hour for 40 hours of preparatory work. Expert witnesses in high-profile cases typically make between $500 to $1,000 per hour."

White House Considers Vetting AI Models Before They Are Released

🤖 AI Summary

アメリカ政府は、Anthropicの強力なMythosモデルなどに続く懸念から、AIモデルが公的にリリースされる前に審査を受けることを検討しています。トランプ政権は前年からAI技術の推進派であり、「この産業を成長させ、 THRIVEさせるべきだ」と述べています。しかし、政府はAIによるサイバー攻撃の政治的な影響を避けるために、新しいモデルが軍事的機能を持つ可能性があることを評価し、早期にアクセスできるようにするためのレビューシステムを検討しています。

詳細には、ホワイトハウスは最近、Anthropic、Google、OpenAIの幹部と会談を行い、政府によるAIモデルの審査について話し合いました。英国のように、いくつかの機関がAIモデルの安全性基準に適合することを確認する方法を検討しています。

この決定はトランプ政権のAIに対する姿勢の一変を示しており、彼は以前、「この産業を政治や規制で止めるな」と述べていました。しかし、現在政府は、AIモデルがサイバーセキュリティ能力を持つ可能性があるため、その早期アクセスを推奨しています。

The Trump administration is reportedly considering an executive order to create a working group that could review advanced AI models before public release. The shift follows concerns over Anthropic's powerful Mythos model and its cyber capabilities, with officials weighing whether the government should get early access to frontier models without necessarily blocking their release. The New York Times reports: In meetings last week, White House officials told executives from Anthropic, Google and OpenAI about some of those plans, people briefed on the conversations said. The working group is likely to consider a number of oversight approaches, officials said. But a review process could be similar to one being developed in Britain, which has assigned several government bodies to ensure that A.I. models meet certain safety standards, people in the tech industry and the administration said. The discussions signal a stark reversal in the Trump administration's approach to A.I. Since returning to office last year, Mr. Trump has been a major booster of the technology, which he has said is vital to winning the geopolitical contest against China. Among other moves, he swiftly rolled back a Biden administration regulatory process that asked A.I. developers to perform safety evaluations and report on A.I. models with potential military applications. "We're going to make this industry absolutely the top, because right now it's a beautiful baby that's born," Mr. Trump said of A.I. at an event in July. "We have to grow that baby and let that baby thrive. We can't stop it. We can't stop it with politics. We can't stop it with foolish rules and even stupid rules." Mr. Trump left room for some rules, but he added that "they have to be more brilliant than even the technology itself." The White House wants to avoid any political repercussions if a devastating A.I.-enabled cyberattack were to occur, people in the tech industry and the administration said. The administration is also evaluating whether new A.I. models could yield cyber-capabilities that could be useful to the Pentagon and U.S. intelligence agencies, they said. To get ahead of models like Mythos, some officials are pushing for a review system that would give the government first access to A.I. models, but that would not block their release, people briefed on the talks said.

🤖 AI Summary

カリフォルニア州の民主党議員アダム・シフが提出した、バイ Partisan LIFT AI法案は、オープンアイ、グーグル、マイクロソフトなどの主要なAI開発企業の支援を受けており、「AIリテラシー」教育をK-12カリキュラムに組み込むことを提案しています。この法案により、国立科学基金(NSF)の新所長は、高等教育機関や非営利団体に対して「AIリテラシー」に関する学習教材や教師研修などの研究開発資金を提供することができるとされています。

法案では、「AIリテラシー」として「適切な年齢に応じた知識と能力を持つこと(AIの有効な使用、出力の批判的解釈、AI世界での問題解決、潜在的なリスク軽減)」が定義されています。この法案にはアメリカ労働者組合連合、グーグル、オープンアイなど13社が賛同しています。

また、教師向けの「AIリテラシー」評価ツールや実践的研修、実践的な学習ツールの開発が支援されます。さらに既存カリキュラムにもAIリテラシーを適切に組み込むことが提案されています。
An anonymous reader quotes a report from 404 Media: A new, bipartisan bill introduced (PDF) by Democratic Senator of California Adam Schiff and endorsed by the biggest AI developers in the world -- including OpenAI, Google, and Microsoft -- would change the K-12 curriculum to shoehorn in "AI literacy," something that young people and teachers alike already hate in schools. The Literacy in Future Technologies Artificial Intelligence, or LIFT AI Act, would empower the new director of the National Science Foundation (NSF) to make grant awards "on a merit-reviewed, competitive basis to institutions of higher education or nonprofit organizations (or a consortium thereof) to support research activities to develop educational curricula, instructional material, teacher professional development, and evaluation methods for AI literacy at the K-12 level," the bill says. It defines AI literacy as using AI; specifically, "having the age-appropriate knowledge and ability to use artificial intelligence effectively, to critically interpret outputs, to solve problems in an AI-enabled world, and to mitigate potential risks." The bill is endorsed by the American Federation of Teachers, Google, OpenAI, Information Technology Industry Council, Software & Information Industry Association, Microsoft, and HP Inc. [...] The grant would support "AI literacy evaluation tools and resources for educators assessing proficiency in AI literacy," according to the bill. It would also fund "professional development courses and experiences in AI literacy," and the development of "hands-on learning tools to assist in developing and improving AI literacy." Most importantly for real-world implications, it would fund changing the existing curriculum "to incorporate AI literacy where appropriate, including responsible use of AI in learning."

GoogleのPixel 11シリーズは、グローバルなメモリ不足の影響でRAM容量が削減される可能性があるとBeauHDによるレポートでは指摘されています。泄露情報によると、ベースモデルは現在の12GBから8GBに、プロモデルは現在の16GB以下の12GB版が追加される見込みです。各モデルには16GBの構成も用意される予定ですが、スペック低下モデルの登場により、16GB版は価格を上げる可能性があります。

また、Proモデルにはカメラ性能向上や明るいディスプレイなどの機能強化も含まれていると報告されています。このメモリ不足はSamsungなど他の携帯電話メーカーにも影響を与え、価格が上昇している状況です。
Google's Pixel 11 lineup could see RAM cuts or lower starting configurations because of the global memory shortage, with leaks suggesting the base model may drop from 12GB to 8GB while Pro models could add 12GB versions below the current 16GB tier. The Verge reports: There will be 16GB configurations available for each, but adding a lower-spec model could mean the 16GB version is getting a price hike. However, the silver lining is that the specs from MysticLeaks also include camera upgrades and brighter displays for the Pro models. The RAM shortage is pushing other phone makers, including Samsung, to raise prices, too.

The Audio Industry Is Grappling With the Rise of 'Podslop'

2026年5月5日 04:00

🤖 AI Summary

現代のポッドキャスト産業では、数千もの新番組が毎日のようにリリースされ、その一部はAI生成である可能性が高い。しかし、どのポッドキャストがAIで作られたのかを正確に特定することは難しくなっている。最近、アマゾンは製品説明のためにクアルティーポッド(擬似的ポッドキャスト)を生成する機能を導入した。

この状況は業界にとって大きな挑戦となっている。例えば、Apple PodcastsではAIを使用して「重要な部分」を作成したクリエイターに表示を要求しており、欺瞞的なコンテンツは禁止されている。Spotifyも具体的なガイドラインを公表していないが、危険や誤解の可能性のあるコンテンツには規則を適用している。

さらに複雑になるのは収益面だ。多くのポッドキャストは無料サービスを利用してアドマーケットプレイスに参加できるため、これらの番組とホスティングサービスは毎回の再生やダウンロードから利益を得ている。Spreakerがこの問題を注視している一方で、AIを使用した番組でも60%の収益配分を受け取るようユーザーに警告している。

しかし、ポッドキャスト「slop」(劣悪な内容)という議論は今や過去の話だという見方もある。 pódstudio Inception Point の共同設立者Jeanine Wrightは、「まだ slop について議論している人は6-7回ジョークを言っているだけだ」と述べている。

この問題には、AI生成コンテンツが広告枠に配られることが受け入れられるか、また「slop」の定義は何であるべきかなど、大きな疑問が残されている。
An anonymous reader quotes a report from Bloomberg's Ashley Carman: Welcome to the modern era of podcasting in which thousands of new shows are released into the world every day with a sizable portion likely being AI-generated. Figuring out exactly which ones fall into that growing category is becoming more difficult just as the industry is starting to take this issue seriously. In only the past month or so, Amazon launched a feature that explains a product by generating a quasi-podcast, complete with co-hosts talking to each other and taking questions from users. Shout out to Business Insider reporter Katie Notopoulos for spotting this (and, naturally, demoing it with an adult diaper rash-cream). Not long ago, Nicholas Thompson, chief executive officer of the Atlantic, noted "podslop" dominated his Spotify search results when he typed in the word "Sora." This was around the time that OpenAI shut down its user-generated, AI-content-only app. [...] All of which raises some big, difficult questions. For one, what should the listening platforms do about this incursion? As of right now, Apple Podcasts requires creators who generated a "material portion" of their show using AI to disclose it. The platform also bans misleading or deceptive content. Spotify hasn't published any specific guidelines around AI, though it maintains general rules around dangerous and misleading content. Where this conversation gets even trickier is when it comes to money. Many of these podcasts are hosted on at least one free service that allows programs to opt into their ad marketplace with zero barrier to entry, meaning these shows (and the hosting service) profit off every listen or download. Spreaker, a company owned by iHeartMedia, is the primary one to watch here. Though it tells users to disclose when they rely on AI, it still allows those shows to opt into its programmatic ad marketplace, which pays creators 60% of the revenue generated by the ads placed in their shows. It stands to reason that most of these thousands of shows don't reach many people. But in the aggregate, the ears and dollars could add up. Are the advertisers on board with being next to AI-generated content, some of which might be deemed "slop?" There's also the question of how to define "slop." Jackson of the Podcast Index and his co-host Adam Curry treat it as something listeners simply know when they hear it, while Alberto Betella, co-founder of RSS.com, defines it as "fully automated content with no human review." Jeanine Wright, co-founder of Inception Point, rejects the debate altogether: "The people still talking about slop are still making 6-7 jokes," she said. "It's still yesterday's conversation."

🤖 AI Summary

GameStopがeBayを560億ドルで買収する非要請オファーを提出したと伝えています。CEOのライアン・コーンは、eBayをAmazonに匹敵する大企業にすることを目指しているとしています。「eBayは今よりも数百億ドル Worth になるべきだ」と彼は述べました。

GameStopはTDバンクから最大200億ドルの債務融資が保証されていることを明らかにしており、同社はeBayに対する株式ポジションを2月4日に構築したと報告しています。Offerは50%キャッシュ、50%GameStop株で構成されています。

eBay側は取引案を審査すると表明し、具体的な検討は株主の価値創出を中心に進めると述べています。取引が受け入れられないと GameStopは株主向け投票戦争を展開する可能性があるとしています。

コーンCEOは自身がeBay運営に最適な人選であると強調し、ゲーム販売業界の経験と Chewy社での実績を挙げています。両社には既存の共通点があり、コレクターズカードなどのセールスを含む競争があります。
GameStop has made an unsolicited $56 billion cash-and-stock offer to buy eBay (paywalled; alternative source), with CEO Ryan Cohen arguing he can turn the marketplace into a far larger Amazon competitor. "EBay should be worth -- and will be worth -- a lot more money," Cohen said in an interview. "I'm thinking about turning eBay into something worth hundreds of billions of dollars." The Wall Street Journal reports: Cohen said GameStop has a commitment letter from TD Bank to provide up to $20 billion in debt financing to help make a deal possible. GameStop delivered an offer letter to eBay on Sunday and released a copy of it following the Journal's report on the details of the bid. Cohen wrote in the letter to eBay Chairman Paul Pressler that GameStop started building its eBay position on Feb. 4. It said its offer consists of 50% cash and 50% GameStop shares. EBay said Monday morning its board and financial advisers would review GameStop's unsolicited proposal. It said there were no discussions with or outreach from GameStop before receiving the offer. Ebay added that it will review the offer "with a focus on the value to be delivered to eBay shareholders, including the value of the GameStop stock consideration and the ability of GameStop to deliver a binding, actionable proposal." If eBay isn't receptive, Cohen said he was prepared to run a proxy fight and take the offer directly to its shareholders. The window for shareholders to nominate director candidates at eBay ahead of an annual meeting scheduled for this June has already closed, according to the company's proxy materials. Cohen told the Journal that putting his videogame retailer and eBay under one roof could create opportunities to cut costs and improve earnings. The two companies have some overlap already, including a focus on selling collectibles such as trading cards. "There is nobody who is more qualified, based on my experience, to run the eBay business," Cohen said, referencing his time at GameStop and previously Chewy, the online pet-products marketplace he co-founded.

Scientists Discover 27 Potential New Planets That Orbit Two Stars

著者: BeauHD

🤖 AI Summary

星の周回惑星として27個の新しい候補が発見されました。アストロノミー誌によると、現在まで宇宙で確認された二つの星を回る惑星は18個に過ぎず、一方で単一の星を回る惑星は6000個以上が確認されています。研究チームは「apsidal precession」と呼ばれる方法を使用し、1590個の星系から36個の候補を選び出し、その内27個は惑星質量である可能性があると指摘しました。

この発見は、星の周回惑星の数がさらに増えることを示唆しています。研究者たちはNASAの「Transiting Exoplanet Survey Satellite」を使ってこれらの潜在惑星を探し、 Monthly Notices of the Royal Astronomical Society にその結果を発表しました。

さらに詳細なスペクトル分析が必要ですが、候補は木星より大きいものから土星と同じサイズまでのものが含まれる可能性があります。
Astronomers have identified 27 potential new circumbinary planets -- worlds that orbit two stars, like Star Wars' Tatooine. "To date, only about 18 circumbinary planets ... had been identified in the universe," reports the Guardian. "More than 6,000 planets have been discovered that orbit single stars, like Earth does around the sun." The Guardian reports: In a timely publication for May 4, also known as Star Wars Day, scientists have identified nearly 30 more candidate planets, whose distances range from 650 to 18,000 light years away from Earth. [...] More than half of the stars in the universe exist in binary or multiple star systems. The researchers instead used a method known as "apsidal precession," searching for a wobble between stars that orbit around and eclipse each other. "If we monitor the exact timing of these eclipses ... that can tell us that there's something else going on in the system," said Margo Thornton, the study's lead author and a PhD candidate at UNSW. After eliminating other factors such as the rotation and gravitational pull of the two stars, the team identified 36 star systems out of 1,590 whose behavior could only be explained by a third body. For "27 of those objects, it is possible that they are planet mass," Thornton said. More research into their spectra -- the light they emit -- was needed to formally confirm them as circumbinary planets, she said. "It's just a matter of: what is the mass of it? Is it a planet? Is it a brown dwarf? Is it a star?" The team discovered the potential planets -- which likely range from Neptune-sized to ten times heavier than Jupiter -- using data from Nasa's Transiting Exoplanet Survey Satellite, a planet-hunting space telescope that launched in 2018. The research was published in the Monthly Notices of the Royal Astronomical Society.

Infrasound Waves Stop Kitchen Fires, But Can They Replace Sprinklers?

🤖 AI Summary

サブウーファーによる音波が調理場の火災を鎮火させるというデモが行われ、その有効性について議論されている。California Concordで行われたこの試験では、AI駆動センサーが煙探知器が鳴る前に、壁から放出されるサブウーファーの音波によって火災が鎮火した。

サウシン・ファイヤテック社は、音波による消防法を現実化しようとしており、従来の消火栓システムよりも家屋の水損を防ぐことが期待されている。しかし専門家の一部は、この技術が家庭や山林での火災対策で置き換える可能性について疑問視している。

音波は小さな炎を鎮火させる効果があるものの、熱い表面や湿った燃料の冷却には役立たずとされ、再燃や潜伏する火災などのリスクが高まると指摘された。サウシン・ファイヤテック社は第三者認証とNFPA 13D相当性を主張しているが、詳細なテスト結果は公開されていない。

消防当局と外部観察者は、信頼性、メンテナンス、校正、システムの故障検知方法についてもっと情報が必要だと指摘した。
An anonymous reader quotes a report from Ars Technica: In a makeshift demonstration kitchen in Concord, California, cooking oil splatters in and around a frying pan, which catches fire on an unattended gas stove. Within moments, a smoke detector wails. But in this demonstration, something less common happens: An AI-driven sensor activates and wall emitters blast infrasound waves toward the source of the fire in an attempt to put it out. The science of acoustic fire suppression, which has long been known and documented in scientific literature and the press, works by vibrating oxygen molecules away from a fuel source, depriving the fire of a critical component needed for combustion. Indeed, after just a few seconds of infrasound, the tiny kitchen blaze goes out. "We were able to not just point-and-shoot like a fire extinguisher; we figured out how to run it through ducting and distribute it like a sprinkler system," said Geoff Bruder, co-founder and CEO of Sonic Fire Tech, during the presentation. The company's goal is to replace sprinklers, which are effective at stopping fires but can also do significant water damage to a property. Sonic Fire Tech appears to be the first company trying to commercialize the science of acoustic fire suppression. Its executives have already been touring Southern California; Wednesday's event was the first in the northern half of the state. The company aims to make this infrasound technique mainstream in both commercial (for instance, a data center, where sprinklers would damage electronics) and in-home installations, given that sprinklers are already required in all new California homes built in 2011 and later. Sonic Fire Tech also hopes to produce a backpack-based system that could be worn by wildland firefighters headed out into the field. "We are making meaningful technological improvements on a monthly basis," Stefan Pollack, a company spokesperson, emailed Ars after the event. But two experts who spoke with Ars raised serious questions about the potential for this technology to supplant traditional sprinklers in a home. They are even more skeptical as to whether the technique can be effective in an uncontrolled wildfire situation, where flames can grow very quickly. Experts are concerned that infrasound may knock down small flames but does not cool hot surfaces or wet fuel like sprinklers do, which raises the risk of re-ignition, smoldering fires, hidden fires, or blocked fires. Sonic Fire Tech has claimed third-party validation and possible NFPA 13D equivalency, but it has not publicly released full testing details. Fire officials and outside observers also want more information about reliability, maintenance, calibration, and how system failures would be detected and communicated.

🤖 AI Summary

インターネット・マター研究所の調査によると、英国で3割以上の子供がソーシャルメディアやオンラインプラットフォームでの年齢確認措置を回避したと報告しています。さらに、研究によれば、6人の親のうち1人が子供に年齢確認を绕道させた経験があると言明し、子供たちは「プラットフォームを欺いて年齢を高らせる」という手法を使用していることも判明しました。一部の親は眉ペンシルを使って髭を描くことで年齢認証を逃れることも確認されました。
調査結果によると、1000人の英国子供のうち46%が年齢確認は容易に回避できると考えており、32%が実際にその手法を使用していると認めていました。また、49%の子供たちが有害なコンテンツに遭遇したという報告もあり、インターネット・マター研究所はこの結果を「不十分」として、実際には年齢認証措置が無効であるか容易に回避できると主張しました。
The Independent reports that "more than a third of children in the UK have found a way around age verification measures" for social media sites and other online platforms. And new research from online safety organisation Internet Matters "suggests one in six parents have helped their child to get past age verification checks, with children reporting 'tricking' platforms into thinking they are older. " Parents also said they had caught their children drawing on facial hair in a bid to evade the technology. One mother said: "I did catch my son using an eyebrow pencil to draw a moustache on his face, and it verified him as 15 years old"... From a sample of 1,000 UK children, 46% said they believed age checks are easy to bypass, while 32% admitted to having done so. 49% of the children surveyed said they'd still encountered harmful content, according to the online safety activists. The group called the figure "unacceptable," and complained that age verification measures "are often ineffective in practice or easy to bypass."

Can Investors Trust AI Sales Figures? Asks Wall Street Journal Opinion Piece

著者: EditorDavid
2026年5月4日 16:34

🤖 AI Summary

Wall Street Jouournalの記事は、人工知能(AI)会社が「問題のある傾向」を示していると警告しています。特定のAI企業がパートナーに製品を使用するよう支払いを行うことで、自身の収益成長が実質的な需要によるものか補助金受領によるものか区別がつきにくい状況が生じていると指摘しています。

記事は、OpenAIの15億ドル、Anthropicの2億ドル、Googleの7,500万ドルという大規模な資金提供事例を挙げています。これらの合弁事業を通じて、プライベートエクイティファンドが関与する同業他社は正常な発展と人工的な財務工学を区別するのが難しくなる可能性があると述べています。

投資家向けの警告を発したロバート・ポゼン氏は、米国最大の共同基金会社の会長を務めた経験があり、MITビジネススクールで講師を務めています。彼は、AI企業が上場準備を行う際には慎重に財務情報を評価するよう投資家に呼びかけるとともに、補助金や合弁事業によって急速に採用されているAIツールの普及について懸念を示しています。

ポゼン氏は投資家のためのアドバイスとして、「補助金を受けているセグメントからの企業収益の割合」を求めることを提案しており、その割合が高い場合、これらの会社に対する収益見込みに疑問を呈することも重要であると指摘しています。
A Wall Street Journal opinion piece warns of "a troubling trend" in AI's growth. "Rather than selling software, some AI companies are paying their partners to use it." It cites OpenAI's $1.5 billion joint venture with private-equity firms, Anthropic's $200 million contribution to a private-equity firm joint venture, and Google's $750 million subsidization of Gemini's adoption by consulting firms. "These agreements muddy the distinction between a company's sound growth trajectory and artificial financial engineering." [T]he scale and structure of the recent AI deals go beyond standard incentive mechanisms... When a seller pays customers to buy its products, it is unclear if its revenue growth reflects vibrant demand or a willingness to accept subsidies. Slashdot reader destinyland writes: This warning comes from a prominent figure in the investing community. For six years Robert Pozen was chairman of America's oldest mutual fund company, after five years at Fidelity. An advocate for corporate governance, he's currently a lecturer at MIT's business school (and the author of the book Remote Inc.: How to Thrive at Work...Wherever You Are). "As AI companies prepare initial public offerings, investors should scrutinize their numbers closely," Pozner writes, warning about "time-limited financial support". "In evaluating AI sales figures, analysts should consider the distorted incentives that the recent financing deals create," writes Pozner: Private-equity firms, enticed by promised returns, might demand rapid rollouts of AI products, rather than ensuring their orderly and safe development. Portfolio companies of private-equity firms may embrace AI tools not because they are needed but because adoption is mandated by their owners. Consultants may favor one set of AI models based on the subsidy instead of the merits. If guarantees and subsidies are major factors in the rapid adoption of AI tools, investors should be skeptical of AI companies' revenue projections. Many of their customers enticed by consultants will stop paying full price when the financial incentives are gone. Many of the portfolio companies of private-equity firms could back away from selected AI tools once these joint ventures expire. The challenge with evaluating these AI financing deals is the lack of transparency. At present, AI vendors don't separate revenue driven by subsidies or joint ventures from standard sales. The lesson from the telecom debacle is that financial engineering can obscure, for years, the difference between real customer demand and demand driven by incentives. When AI companies begin to finance their own product distribution, guaranteeing returns to investors and subsidizing sales, it's a signal for investors to dig deeper. Investing in an AI company? Ask what percentage of enterprise revenue is coming from subsidized channels or joint ventures, Pozner suggests. And the renewal/retention rate for customers not supported by subsidies or joint ventures...

🤖 AI Summary

Robloxは、チャットアクセスのための強制的な年齢認証導入が主要な逆風となり、2026年の収益見通しを約9億ドル下方修正した。結果的に、株価は前場取引で21.85%下落。全米ユーザーの65%が認証を完了しているものの、51%のグローバル日間アクティブユーザーが認証を受けている状況では、新規利用者獲得に影響が出ているという。一方で、デイリーアクティブユーザーは35%増加し、利用時間も43%増えた。

Robloxは、安全対策によって2026年の売上高成長見通しを下方修正するとともに、「プラットフォームの基本的な強化」を通じて長期的には成長可能性が高まるという立場を示した。しかしながら、法律費として1四半期で5700万ドルの費用を計上している。

Age verification became mandatory for chat access on Roblox in January — and Friday morning Quartz reported it's apparently impacted the company's financials: Roblox cut its full-year 2026 bookings forecast by roughly $900 million at the midpoint on Thursday, blaming stronger-than-expected headwinds from its mandatory age-verification rollout on an audience that skews heavily toward children and teenagers. Full-year 2026 bookings are now projected at $7.33 billion to $7.60 billion, a range that sits roughly $900 million below the prior guidance of $8.28 billion to $8.55 billion; analysts had expected $8.38 billion, according to Yahoo Finance. Roblox stock fell almost 22% in premarket trading.... Daily active users rose 35% year over year to 132 million, while hours engaged climbed 43% to 31 billion hours... Daily Active Users and hours engaged fell below forecasts of 143.8 million and 33.68 billion, respectively, according to Yahoo Finance... Users who have not completed age checks have faced restricted communication features, and the process has weighed on the platform's ability to bring in new users. Russia's blocking of the platform, which took effect in December 2025, added further drag on user growth, according to Yahoo Finance. As of the end of the first quarter, 51% of global daily active users had completed age verification, with 65% of U.S. users having done so, Roblox said.... The safety push has come with legal costs. Roblox accrued $57 million in the first quarter for settlements and settlement proposals with certain states over youth-related consumer protection and digital safety matters, with payments structured over multiple years, the company said. Roblox acknowledged in a letter to shareholders that "our aggressive push to enhance safety lowers our expectations for topline growth in 2026." But they argued that it also "makes our platform fundamentally better and amplifies the long-term growth potential of Roblox through more effective content targeting, tailored communication experiences, and improved community sentiment."

"So yesterday the Devteam (it is always the Devteam) released version 5.0 of legendary and venerable rogueike compuer game NetHack," writes the Rogue-like games column @Play. "It is 39 years old..." MilenCent (Slashdot reader #219,397) writes: In addition to play changes it's left for players to discover, this version updates the code to compile with C99, makes it much easier to cross compile the code for other systems than the one running, and now uses Lua for its dungeon generation. Happy hacking! For new players, "Nethack 5.0 now has an optional tutorial in the early phases of the game that might help you," notes the Rogue-like games column @Play: Three systems binaries are provided: Windows, MS-DOS and Amiga. Yes, Nethack still supports MS-DOS, and yes, it still supports classic Amiga: it explicitly supports AmigaDOS 3.0, meaning it can still run on 68000 machines... That these are the only systems they provide binaries for shouldn't be seen as an indication that these are the "most important" platforms for Nethack, it's more that, since it's entirely open source, building it yourself is entirely possible, and more expected than with most software. Nethack can be built for Linux, Windows 8-11, AmigaDOS, MacOS (I'm not sure if this includes classic Mac too but it might), Windows CE (wow), OS/2 (additional wow), BeOS, VMS and multiple Unixes... Another option is to play through public Nethack servers. The most popular of these are probably alt.org and Hardfought.

🤖 AI Summary

OpenAIがコーデックスアプリにAI生成のペットを導入しました。これらの「オプションなアニメーション付き同伴者」はコーデックス自体がコードを作成しないものの、開発者がコーデックスの進行状況を把握するためのフロートウィンドウとして機能します。通知やタスク完了の確認など、開発者が現在作業中のアプリから切り離さずにコーデックスの動向を知ることができます。

初期には猫や犬などの8種類が標準で用意されており、さらにユーザーはCodexに直接依頼して独自のペットを作成し共有できます。既存の作品にはドラゴンボールの主人公「Gojo」、パトリック・スター( SpongeBob SquarePants)、元Microsoftのキャラクター「クラピー」、OpenAI CEOのサム・アルトマン、Anthropic CEOのダリオ・アモデイ、そして当然のごとくゴブリンなどのものがあります。

この機能は Slashdot の記事から引用しました。
"Vibe coding just got a whole lot more adorable," writes Engadget: OpenAI introduced AI-generated pets to the Codex app, its agentic tool that helps with coding. These "optional animated companions" don't do any coding themselves, but serve as a floating overlay that can tell you what Codex is working on, notify you when Codex completes a task or whether it needs your input on something. The new feature lets developers see Codex's active thread, without having to switch away from your current open app. "The feature ships with eight built-in variations — including a cat and dog," reports Mashable. "But the more interesting play is the custom pet creator." Users can prompt Codex directly to generate their own companion, then share it online. A quick scroll through the homepage reveals the community has already gotten to work. Current creations include Goku, Patrick Star, Microsoft's long-retired Clippy, OpenAI CEO Sam Altman, Anthropic CEO Dario Amodei, and — naturally — a goblin. There's also Grogu, Dobby, a tiny Bob Rossi, and a "Doge-style Shiba Inu dog"...

🤖 AI Summary

AIカメラが西米国の森林火災の早期検知に活用される

3月のある日、アリゾナ州ココノイ NATIONAL ForestのAIカメラで煙のようなものが検出されました。人間のアナリストが雲や埃ではないか確認し、 estadoの森林サービスと最大電力会社に連絡しました。 Arizona Public Serviceが設置した数十台の中の1つが、 Diamond Fireの早期兆候を捕らえました。消防隊員たちは迅速に駆けつけ、面積7エーカー(2.8ヘクタール)未満で火災が拡大する前に消火しました。

極端な暑さと雪不足により、西米国の森林火災の危機感が高まっています。 アリゾナ州などはAIを早期火災検知に導入し、人命や財産を救うことを目指しています。 Arizona Public Serviceには現在40台のAI煙検出カメラがあり、夏までに71台へ増設する計画です。また、アリゾナ州消防庁は7台を展開しています。

Pano AIは2020年から導入され、オーストラリアやカナダ、アメリカの17州で使用されています。同社技術は昨年、全米725件の森林火災を検知しました。

Cindy Kobold(アリゾナ公共サービス気象学者)によると、AI技術は911通報よりも平均45分早く通知します。
The Associated Press reports: On a March afternoon, artificial intelligence detected something resembling smoke on a camera feed from Arizona's Coconino National Forest. Human analysts verified it wasn't a cloud or dust, then alerted the state's forest service and largest electric utility. One of dozens of AI cameras installed for the utility Arizona Public Service had spotted early signs of what came to be known as the Diamond Fire. Firefighters raced to the scene and contained the blaze before it grew past 7 acres (2.8 hectares). As record-breaking heat and an abysmal snowpack raise concerns about severe wildfires, states across the fire-prone West are adding AI to their wildfire detection toolbox, banking on the technology to help save lives and property. Arizona Public Service has nearly 40 active AI smoke-detection cameras and plans to have 71 by summer's end, and the state's fire agency has deployed seven of its own. Another utility, Xcel Energy in Colorado, has installed 126 and aims to have cameras in seven of the eight states it serves by year's end... ALERTCalifornia is a network of some 1,240 AI-enabled cameras across the Golden State that work similar to the system in Arizona.... Pano AI, whose technology combines high-definition camera feeds, satellite data and AI monitoring, has seen a growing interest in its cameras since launching in 2020. They've been deployed in Australia, Canada and 17 U.S. states, including Oregon, Washington and Texas... Last year, its technology detected 725 wildfires in the U.S., the company said... Cindy Kobold, an Arizona Public Service meteorologist, said the technology notifies them about 45 minutes faster on average than the first 911 call.

Carbon Pollution Is Making Food Less Nutritious, Risking the Health of Billions

著者: EditorDavid
2026年5月4日 07:29

🤖 AI Summary

新規のメタ分析は、食物中の栄養素が過去40年間減少していることを示唆しています(Washington Post)。この現象の背景にある「不可視の要因」は二酸化炭素による汚染です。大気中の二酸化炭素濃度が上昇し、これに主な原因をなす化石燃料の燃焼があることから、植物の成長に強い影響を与えています。

例えば、小麦やブロッコリーなどの多くの重要な作物は、ビタミンやミネラルが減少しています。これにより、今日の食事は祖父が食べていたものより栄養価が低い可能性があります(Kristie Ebi 教授)。富裕国の人は強力な医療システムがあり、この変化に対処できる手段がありますが、世界最貧困層や最も脆弱な人々には大きな影響が出るでしょう。この現象は2050年頃までに、10億以上の女性と子供を鉄欠乏性貧血のリスクにさらす可能性があるとされています。

植物は二酸化炭素が光合成を行うのに必要ですが、大気中の二酸化炭素が増えたからといって必ずしもよく成長するわけではありません。32種類の化合物について43種類の作物を調べた結果によると、ほとんどの食物が二酸化炭素濃度上昇によって害を受けていることが分かっています。この研究は1980年代末からの平均的な栄養素減少率が約3.2パーセントであると結論付けています。

この問題の影響は非常に大きく、世界的な食料不足に深刻な悪影響を及ぼす可能性があります。
A new meta-analysis found nutrients in food decreased over the last 40 years, reports the Washington Post. "Many of humanity's most important crops — including wheat, potatoes, beans — contain fewer vitamins and minerals than they did a generation ago." "The invisible culprit behind this damaging phenomenon? Carbon dioxide pollution." Surging concentrations of carbon in the atmosphere, caused largely by burning fossil fuels, have produced potent changes in the way plants grow — from increasing their sugar content to depleting essential nutrients like zinc... "The diets we eat today have less nutritional density than what our grandparents ate, even if we eat exactly the same thing," said Kristie Ebi, a professor at the University of Washington's Center for Health and the Global Environment. People in wealthy countries with strong health care systems will have many tools to cope with the change, experts said. But for the world's poorest and most vulnerable, the consequences could be devastating. One study concluded that by the middle of the century the phenomenon could put more than a billion additional women and children at risk of iron-deficiency anemia — a condition that can cause pregnancy complications, developmental problems and even death. Meanwhile, some 2 billion people across the globe who already suffer from some form of nutrient shortage could see their health problems grow even worse. "The scale of the problem is huge," Ebi said. Plants depend on carbon dioxide to perform photosynthesis — but that doesn't mean they grow better when there's more carbon in the air, scientists say. A sweeping survey of changes among 32 compounds in 43 crops found that nearly every plant that humans eat is harmed by rising CO2 levels... On average, they found, nutrients have already decreased by an average 3.2 percent across all plants since the late 1980s, when the concentration of carbon dioxide in the atmosphere was about 350 parts per million.

🤖 AI Summary

テキサス州アUSTIN南郊のスタートアップは、ロボットを使用して地元で採取した粘土を使って住宅を建設していることを地元ニュース局が報告しています。材料は現場で集められ、混合され、構築プレートに配置されます。その後、上から降りてくるロボットは爪で粘土を拾い、壁に運び設置します。さらに同ロボットはハンマーの装備を変更し、粘土を押压缩成します。「人間がアドオーブ家の建設を行うのを模倣している」とソフトウェアエンジニアのAnastasia Nikoulinaは述べています。システムは機械学習を使用して壁の状況を評価し、平らで堅固な表面を作り出するために建設方法を調整しています。

このプロジェクトはLockhartとLuling間にあるスタートアップが新しい技術をテストするための ranch「Proto-Town」で進行中です。同社は年内に20軒以上の住宅を建設する計画です。
A startup south of Austin is using robots to build homes out of clay pulled directly from the ground, reports a local news station: The materials are gathered on site, mixed, and placed on a build plate. From there, a robot lowers from above, picks up the clay with a claw, carries it to the wall and drops it into place. Later, the same robot switches tools, using a hammer attachment to pound the material into shape. "It's kind of trying to replicate how a human might build an adobe house," said software engineer Anastasia Nikoulina... Using machine learning, the system constantly evaluates the wall, adjusting how it builds to create a flat, solid surface... The project is underway at Proto-Town, a ranch between Lockhart and Luling where startups test new technologies, from anti-drone systems to nuclear reactors. The company plans to build their next home on the property, with hopes to do more than 20 homes over the next year.
