Executive Summary
President Trump signed an executive order on Monday directing federal health agencies to split the combined measles, mumps and rubella vaccine into three separate shots, drawing swift condemnation from major medical organizations and at least two Republican senators as the nation grapples with its largest measles outbreak in 35 years. The order came as U.S. forces fired Hellfire missiles at a Panama-flagged cargo ship attempting to breach the naval blockade of Iranian ports, the third such forcible halt since the blockade resumed last month, while Iran reiterated that the Strait of Hormuz will remain closed until Washington ends the war and unfreezes Iranian assets. Oil prices climbed on the heightened tensions, with Brent crude rising to near $90 a barrel, as a 7.4-magnitude earthquake in western Colombia killed at least 216 people and rescue teams continued pulling survivors from collapsed buildings more than 24 hours after the tremor.

Anthropic and OpenAI Models Make Breakthroughs in Mathematics, Raising Questions About AI’s Role in Discovery
Anthropic announced this week that an unreleased artificial intelligence model made significant progress on the Riemann hypothesis, a 150-year-old problem in mathematics, by testing 650 ideas across 60 sub-agents over 36 hours at a cost of $31 million. The model improved the lower bound of solutions for which the hypothesis holds, a result that was confirmed by the company’s in-house mathematicians and formalized in the Lean proof assistant. Separately, an Anthropic researcher credited the model Claude Fable 5 with finding a counterexample to the 87-year-old Jacobian conjecture, suggesting the conjecture is false in dimensions higher than two.
OpenAI also disclosed that its internal “Astra” model solved ten long-standing mathematics problems, including advances in sphere packing and error-correcting codes. The announcements signal that AI systems are moving beyond computational assistance into genuine mathematical discovery, potentially accelerating progress in fields that underpin cryptography and data transmission.
The advances come alongside new research revealing both the inner workings and vulnerabilities of frontier models. Researchers at the University of Tübingen and other institutions extracted hidden reasoning traces from large language models, uncovering evidence that Chinese AI systems may have been distilled from American models and exposing a vulnerability to personal information leakage. A separate paper showed that Claude Opus 4 and 4.1 exhibit functional introspective awareness, able to identify injected concepts and distinguish their own outputs from artificial prefills. It is unclear how quickly AI companies will patch the reasoning trace extraction vulnerability, or whether the mathematical results will withstand independent peer review.
Intel Seeks Approval for $20 Billion Stock Sale as Alibaba Tests Paid AI Tiers
Intel chief executive Lip-Bu Tan sought and received informal approval from Commerce Secretary Howard Lutnick for a $20 billion secondary stock sale, the company’s first since 1971, to fund artificial intelligence projects including its delayed chip factory in Ohio. The government declined to participate in the offering, which will dilute its 9.9 percent stake—a position that has gained 375 percent since the Commerce Department invested a year ago. The move signals confidence in Intel’s turnaround under Tan, whose position was previously threatened by President Trump.
Meanwhile, Alibaba has begun testing paid tiers for its AI office assistant QwenWork, with annual subscriptions ranging from 200 yuan, or about $29.60, to 1,499 yuan, plus optional video generation credits. The Chinese e-commerce giant is seeking to monetize its AI offerings to offset rising infrastructure costs, joining a broader industry push to turn generative AI from a capital-intensive experiment into a sustainable business. Whether users will pay for tools that have largely been free remains an open question.
Geopolitics & Security
U.S. Fires on Cargo Ship as Iran Hardens Stance on Strait of Hormuz
The United States military fired two Hellfire missiles at a Panama-flagged cargo ship attempting to sail toward an Iranian port on Tuesday, disabling its steering gear after the vessel ignored repeated warnings, according to U.S. Central Command. The strike on the M/V Vela Nova marks the third time American forces have forcibly halted a vessel since the naval blockade of Iranian ports resumed on July 14. Centcom said it has now redirected 55 commercial ships, disabled three, and boarded two others.
The escalation came as Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, reiterated that the Strait of Hormuz will remain closed until Washington meets a set of conditions, including ending the blockade, releasing frozen Iranian assets, and agreeing to a region-wide ceasefire in Gaza and Lebanon. Rezaei said additional undisclosed demands had been passed to Washington through mediators. Vessel traffic through the strait has collapsed to just six commodity ships on Monday, down from an 11-ship average over the previous ten days, according to data from Kpler. Crude exports through the waterway have fallen to roughly 2.2 million barrels per day, compared with about 20 million barrels before the conflict began in February.
President Trump told reporters on Monday that the U.S. Navy has “100 percent” control of the strait and floated the idea of Iran paying reparations to the United States for past attacks, introducing a new sticking point in already stalled negotiations. Qatar reported that Omani-mediated talks over future shipping arrangements are making “major progress,” but Iran insists the strait will not fully reopen without American concessions. Oil prices rose on the uncertainty, with Brent crude gaining about 1.24 percent to $90 a barrel and West Texas Intermediate rising 1.3 percent to $84.30.
Trump Secretly Switched Planes in Turkey After Iran Threat Detected
President Trump was secretly moved between aircraft via a catering truck during a NATO summit in Ankara last month, after U.S. officials detected a credible Iranian threat to fire a missile at Air Force One, according to The Washington Post. The operation involved Trump boarding the older presidential jet in view of cameras before being smuggled out to a smaller C-32A military aircraft. The press pool and some White House staff were told to close window shades and remained unaware he was no longer aboard.
The White House has not confirmed the switch, but Trump said the decision was “up to the Secret Service.” The threat is the latest in a series of Iranian assassination plots against Trump and former officials linked to his 2020 order to kill Qassem Soleimani, the commander of Iran’s Quds Force. The ruse raises questions about the security of presidential travel abroad, particularly the use of a Qatari-donated Boeing 747-8 that lacked full missile-defense systems. It is unclear whether the Secret Service will adjust its protocols for future summits or accelerate retrofitting of the presidential fleet.
Russian Strikes Kill Six in Zaporizhzhia as Ukraine’s Drone Campaign Falters
Overnight Russian attacks killed at least six people in Zaporizhzhia and wounded 19, with Ukrainian President Volodymyr Zelenskyy accusing Moscow of using North Korean ballistic missiles. The strikes also hit a children’s hospital in Kyiv, wounding one person, and a drone attack in Mykolaiv injured a 75-year-old woman. Russia’s Defense Ministry said the attacks targeted defense industry facilities and transport and logistics centers.
The barrage came as Ukraine’s 40-day deep-strike campaign, launched by Zelenskyy to pressure Russia into peace talks, expired without achieving its goal. Despite hitting Russian oil refineries and logistics hubs, Moscow has not softened its stance, and President Vladimir Putin remains unwilling to make concessions. Zelenskyy has requested South Korean air defense systems, warning that 30,000 to 50,000 North Korean troops are now deployed in Russia. The failure of the campaign leaves Kyiv facing the same stark choice: continue a costly war or negotiate largely on Russian terms.
In a sign of the conflict’s widening spillover, Bulgaria summoned Ukraine’s ambassador after a Ukrainian-made decoy drone exploded near a gas pipeline, marking the first such incident on Bulgarian territory since 2022. The episode highlights the risks for NATO members as the war grinds into its third year.
Netanyahu Rejects U.S.-Backed Gaza Peace Plan
Israeli Prime Minister Benjamin Netanyahu publicly rejected the 15-point Gaza peace plan brokered by the Trump administration, insisting that the Israeli military will not withdraw from Gaza until Hamas is fully disarmed. The rejection came despite Hamas having signed onto the plan, which envisioned a phased disarmament in exchange for Israeli withdrawal. Netanyahu’s stance, delivered twice at a Cabinet meeting, underscores a deepening rift with Washington and complicates American efforts to stabilize the region ahead of Israeli elections in October.
Reported Palestinian deaths in Gaza dropped sharply from 47 to 8 in the week following the initial disarmament announcement, according to the Gaza Health Ministry. But the ceasefire remains fragile, and it is unclear whether the Trump administration will pressure Netanyahu to reconsider or allow the plan to collapse.
Economy & Markets
Yen Erases Half of Intervention Gains as Carry Trades Return
The Japanese yen has weakened to over 159 per dollar, erasing about half of the gains from a historic U.S.-Japan intervention less than two weeks ago, when it had strengthened to 155 after crossing 163. The intervention, which involved coordinated action by Washington and Tokyo, initially reset market psychology but has not eliminated the fundamental forces pressuring the currency.
“Intervention has scared markets, but has not stopped the laws of finance which say money flows in the direction of maximum returns,” said Jesper Koll, expert director at Monex Group. “As long as the cost of money in Japan is lower than the return overseas, carry trades will re-assert.” The core issue remains the yield gap between Japan and the United States, which continues to incentivize investors to borrow cheaply in yen and invest in higher-yielding assets. Higher Treasury yields and elevated oil prices, particularly problematic for energy-importing Japan, have further restored macro forces favoring the dollar. It is unclear whether Tokyo will intervene again or accept further depreciation.

Trump Orders MMR Vaccine Split, Drawing Fire From Medical Establishment and Some Republicans
President Trump signed an executive order on Monday overhauling federal childhood vaccine recommendations, including a directive to split the combined measles, mumps and rubella vaccine into three separate shots. Trump claimed without evidence that the combined vaccine could be “quite lethal” and linked vaccines to autism, a connection repeatedly disproven by scientific studies. The order also reclassifies several vaccines, recommending hepatitis A, hepatitis B, meningococcal and dengue vaccines only for high-risk children.
The order drew swift and unified opposition from major medical organizations. Dr. Willie Underwood III, president of the American Medical Association, said the order puts “children’s health at risk,” while Dr. Jan K. Carney of the American College of Physicians called it part of a “troubling pattern” of unilateral changes to vaccine guidance. Republican Sen. Bill Cassidy of Louisiana, a physician, said “This executive order is wrong” and reiterated that vaccines do not cause autism. Sen. John Cornyn of Texas posted data from The Lancet showing vaccines have averted 154 million deaths since 1974, including 146 million among children under five.
The American Academy of Pediatrics estimates it would take a decade to develop separate vaccines for each MMR component. Experts note the order is unlikely to have immediate practical impact, as states control their own vaccination schedules and the federal recommendations serve as guidelines. But public health officials warn that splitting the MMR vaccine could lead to more missed or delayed vaccinations, potentially worsening the largest U.S. measles outbreak in 35 years. Roughly 9 percent of parents report skipping or delaying the MMR vaccine for their children, according to a 2025 survey by KFF and The Washington Post.
Colombia Earthquake Kills 216 as Rescuers Pull Survivors From Rubble
A 7.4-magnitude earthquake struck western Colombia on Monday morning, killing at least 216 people and leaving hundreds missing, with thousands of homes damaged or destroyed across Cali, Pereira, and Manizales. Rescue teams, including soldiers, firefighters, and volunteers, pulled several survivors from collapsed buildings, including a 32-year-old woman in Cali and a 31-year-old woman after a 16-hour operation. The quake, the strongest in a century, prompted President Abelardo de la Espriella to declare a national disaster, with local mayors reporting overwhelmed hospitals and dozens of collapsed structures.
The disaster has also drawn attention to corporate conduct during emergencies. U.S.-based Blackstone Medical Services faced backlash after a manager warned employees against leaving work during the quake. Former Labor Minister Antonio Sanguino called for government intervention, and it is unclear whether the company will face regulatory scrutiny.
Wildfires Burn Across Four Continents as Heat Records Loom
Wildfires are burning across multiple regions worldwide, from the western United States and Canada to Indonesia and the United Kingdom, driven by hot, dry conditions and exacerbated by climate change. In the U.S. and Canada, at least 200 major wildfires are active, with significant destruction reported in Spokane, Washington. In the United Kingdom, firefighters are struggling to contain a large blaze in the New Forest that has scorched more than 247 acres of heathland, with peat fires continuing to spread underground. The National Fire Chiefs Council reported July as the busiest month on record for wildfires, with 966 incidents this year.
Indonesia has deployed cloud-seeding aircraft and nearly 50,000 firefighters to combat fires that have burned over 100,000 hectares, closing dozens of schools due to poor air quality in West Kalimantan. The U.K. Met Office said the country is on course for its hottest summer on record, with almost three-quarters of England officially in drought. The simultaneous fires across continents underscore the global scale of wildfire risk as climate change intensifies extreme weather patterns.
Typhoon Dolphin and Tropical Storm Chan-hom Disrupt East Asia
Typhoon Dolphin, the strongest typhoon to hit China this year, triggered mass evacuations and severe flooding across central and northern China, while Tropical Storm Chan-hom lashed Japan’s Tokyo region, leaving thousands without power. In Beijing, authorities evacuated thousands of residents from flood- and landslide-prone areas, closed hundreds of tourist sites, and suspended bus and metro services as the capital braced for more than 150 millimeters of rain in 24 hours—over one-third of its average annual rainfall. More than a million people were evacuated across China, with Hubei province, a major manufacturing hub, under an orange alert for extreme rainfall and landslides.
In Japan, Chan-hom made landfall in Ibaraki prefecture, injuring five people and cutting power to over 3,000 homes during the bon festival holiday week. The Philippines, already hit by Dolphin’s earlier passage, has seen at least 16 deaths from floods and landslides, with Manila’s river surface covered in rubbish after nine days of heavy rain equivalent to more than a month’s rainfall in some areas.

Fauci’s COVID Vaccine Messaging Sparks Renewed Scrutiny
Resurfaced texts revealing Dr. Fauci privately warned colleagues about miscarriage risks while publicly claiming no issues have drawn sharp reactions. @elonmusk amplified the story with a blunt “This really happened,” later adding that “They can’t handle the truth is the real issue here” in response to a European op-ed calling him a fascist for his platform’s role in spreading information. @zerohedge flagged the core contradiction: “Fauci Privately Flagged Miscarriage Risk Before Telling Pregnant Women There Were ‘No Red Flags.’” The thread reveals a deepening distrust of institutional health messaging among these voices.
The AI Acceleration Debate: Pause Calls vs. Full Speed Ahead
A clear tension is emerging between those pushing for AI restraint and those racing forward. @garrytan questioned whether Bernie Sanders’ letter urging Sam Altman, Dario Amodei, and Mark Zuckerberg to pause AI development would “send this to China too,” implying unilateral slowdowns are strategically naive. Meanwhile, @jensenhuang announced NVIDIA’s Nemotron 3.5 Lightning, an open 30B MoE model built for “always-on agents,” signaling no slowdown from the chip giant. @dhh captured the builder enthusiasm, saying he hasn’t been “this excited to jump out of bed and get in front of the keyboard” since discovering Ruby, while @naval drew a line in the sand: “People who are serious about software train their own models.”
AI-Powered Development Reaches New Extremes
The conversation around AI-assisted coding has moved from novelty to staggering scale. @paulg reported meeting a founder who writes 10,000 lines of code a day thanks to AI, preempting skeptics by noting “this is not 10,000 lines of bug-filled crap,” and later teased that another founder sometimes hits 50,000 lines daily. @dhh described using Claude to optimize his home network’s radio channels and mesh settings, calling the experience “SCI-FI.” @tobi noted “10+ PRs overnight” for his Omarchy Quattro tool, while @chamath shared how his firm 8090 replaced manual spreadsheet processes at BISSELL with software that auto-approves 81.4% of parts in seconds at half the cost.
Crypto’s Regulatory Inflection Point
The regulatory landscape for crypto appears to be shifting, though details remain murky. @zerohedge reported the SEC is “poised to unveil major crypto plans as Clarity Act stalls,” suggesting executive action may fill a legislative vacuum. @brian_armstrong announced Coinbase has established Abu Dhabi as its international tokenization hub after securing an FSRA license, framing it as a “big unlock for building a more open, accessible, and global financial system.” The contrast between U.S. regulatory uncertainty and UAE’s welcoming posture is striking.
China’s Soft Power Moment: Tourism and Safety
A nuanced thread emerged around China’s appeal as a travel destination, with personal experience colliding with political critique. @levelsio described China as “having its moment for tourists,” praising the adventure of navigating without shared language and calling locals “some of the friendliest people I’ve ever met.” When challenged with the classic test “can you say your leader is bad without getting in trouble?”, @levelsio countered with his own test: “can you and your partner and kids walk home at night safely alone?” — arguing most Western capitals fail while China, Japan, and Thailand pass. The exchange highlights a growing willingness among some commentators to weigh lived safety against abstract political freedoms.
The Quest for Verifiable and Aligned AI
Technical discussions are converging on making AI both provable and personally aligned. @VitalikButerin analyzed progress on LLM proving, noting “we roughly, sort of, have single-digit (<10x) overhead for LLM proving,” and laid out the ambitious roadmap toward single-digit overheads for fully homomorphic encryption and eventually verifiable FHE. @garrytan emphasized that “deep alignment of your AI with you and your context is massively important,” highlighting River AI’s $1.1 billion raise to build personal AI where users “own everything: the hardware it runs on, the data it learns from, and the intelligence itself.” @EMostaque shared Anthropic’s work applying Claude to the Riemann hypothesis, where it increased the proven lower bound from 41.6% to 67.2% — a reminder that frontier models are making genuine research contributions even without solving the grand challenge.
Meritocracy, Immigration, and Political Realignment
@paulg distilled a tension with characteristic brevity: “You can be pro-meritocracy or anti-immigration, but you can’t be both.” The statement lands amid broader political sorting. @Noahpinion took aim at the DSA, arguing “all the DSA people are the craziest wokey wokes you’ve ever met” and dismissing the notion that the DSA is an alternative to woke politics. @wolfejosh surfaced a resurfaced video of NYC mayoral candidate Zohran Mamdani, calling it “pure cunning machiavellian deceit” rather than psychopathy, while @chamath highlighted a bipartisan House bill requiring federal agencies to inventory legacy IT systems — a reminder that government modernization challenges transcend partisan lines.
