Sun, sand, surf — and kaboom. The US Supreme Court on Wednesday heard Department of the Air Force v. Prutehi Guåhan, a case over whether the Air Force can keep using Tarague Beach, next to Andersen Air Force Base in northern Guam, to detonate unexploded ordnance, Al Jazeera reports. The Air Force has used the beach for detonations since 1982.

The stakes are explosive by the pound: the dispute stems from a 2021 permit application seeking to detonate around 30,000 pounds and open-burn 5,000 pounds of waste munitions, including World War II-era weapons, Courthouse News reports. Guam’s EPA issued a preliminary decision that neither denied nor approved that renewal, and the detonations have continued, per SCOTUSblog.

Prutehi Guåhan — “Protect Guam” in Chamorro — says the range sits on ancestral land the military seized after World War II, next to culturally important fishing grounds, and above an aquifer that provides drinking water to over 80% of the island, Al Jazeera reports. The group wants the Air Force to do a full environmental review under NEPA; the government says the hazardous-waste law, RCRA, displaces that requirement and that the suit was filed too early.

The bench was torn. “This is an odd case,” said Justice Clarence Thomas, noting that it involves “a regulated body asking permission to do something.” Justice Sonia Sotomayor observed that Congress “explicitly does away with NEPA in a bunch of different ways … But they haven’t done it in this context.” Justice Elena Kagan warned of “a gigantic contingency” because Guam’s EPA may not issue the permit the Air Force wants. Law.com read the court as leaning toward the Air Force; Courthouse News said the justices seemed to question “when, not if,” review should happen.

Outside, it was about more than sand. “Guam is a colony of the United States,” said Prutehi Guåhan executive director Monaeka Flores. “We do not have voting representation in Congress. We do not vote for the president.” The island, home to about 170,000 people, has been a US territory since 1898.

Until the justices rule, the Air Force keeps operating under its prior permit, as the group told the court (per SCOTUSblog) — which means the beach stays open. For bombs.

Wall Street’s party hit a wall made of bonds. Stocks closed lower Wednesday as long-dated US Treasury yields resumed their climb, reviving fears about inflation and mounting debt one day after the S&P 500 and Nasdaq hit record closes, Reuters reports. Brent crude briefly crept above $100 a barrel and the 30-year Treasury yield touched a 24-year high.

The scoreboard, per Reuters’ preliminary data: the S&P 500 lost 0.23% to 7,801.15, the Nasdaq dropped 0.24% to 27,533.39, and the Dow fell 355.91 points, or 0.69%, to 51,165.37. Earlier in the session the 30-year yield was at 5.72%, the highest since 2002, according to Reuters via GV Wire; the Motley Fool had the 10-year at 5.31%. Caterpillar fell more than 6% after an analyst downgrade, and Webull tumbled 20% on reports a congressional committee raised concerns about its China connections.

Now the part that hits your kitchen table: the average 30-year fixed mortgage rate jumped to 7.49% from 7.30% — the highest in almost three years — and mortgage applications fell 4.2% in the week ending Oct. 2, the Mortgage Bankers Association said, per HousingWire. Refinance applications were 56% below a year ago. “Very few homeowners have an incentive to refinance at these rates,” said MBA deputy chief economist Joel Kan. Homebuilder stocks slid 2.9%, Reuters says.

Then the Fed dropped its homework. Minutes of the Sept. 15–16 meeting — where officials voted unanimously for a quarter-point hike to 3.75%–4.00% — show policymakers divided over why they hiked: some to keep energy and other price shocks from spreading, a more hawkish core to guard against demand-driven inflation, Reuters reports. “Most participants assessed that another increase in the target range for the federal funds rate would likely be appropriate by year end,” the minutes said.

Markets aren’t betting on October, though: traders price less than a 20% chance of a second straight hike at the Oct. 27–28 meeting, down from 37.6% a week ago, per CME FedWatch, Reuters says. Stocks pared losses after the International Energy Agency agreed to speed the release of oil stocks, prioritizing diesel.

Bottom line: oil up, yields up, mortgages up — and the only thing going down is the number of people who can afford a house.

Check your boarding pass — and the sky. Houthi attacks on two Saudi airports killed three civilians and injured 36 on Tuesday and Wednesday, Saudi Arabia’s General Authority of Civil Aviation said, per Al Jazeera.

The toll: at Abha International Airport in the south, two female residents — one Moroccan, one Algerian — were killed and 28 people were hurt. At King Khalid International Airport in Riyadh, a Sudanese citizen was killed and eight were injured, including five Saudi citizens, The National reports. The aviation authority said injuries ranged from minor to serious and the strikes caused “some material damage.”

The Iran-backed rebels claimed both hits: drones at Riyadh, ballistic missiles and drones at Abha and the Khamis Mushait airbase. Flightradar24 said flights at King Khalid were halted for more than an hour Wednesday morning after a hold of a few hours on Tuesday, and the airport’s website was down for a second straight day. The Saudi-led coalition said it intercepted missiles and drones around Khamis Mushait and Jazan and kept hitting launch sites.

Yemen got it too. Aden’s Transport Ministry said two ballistic missiles and several explosive-laden drones were fired at the city’s international airport around daybreak; one missile landed near the runway minutes before Yemenia Airways flight 603 from Cairo was due in, and the flight was diverted to Jeddah. No casualties were reported. Houthi spokesman Brig. Gen. Yahya Saree claimed strikes on Saudi military camps “killed and wounded dozens” — claims that could not be independently verified.

The backdrop: Saudi-backed Yemeni government forces are locked in escalating combat with Houthi fighters who seized a broad swath of territory astride the strategic Bab al-Mandeb strait, Al Jazeera reports. Yemen’s legal affairs minister said Houthi shelling in Taiz province killed six civilians and wounded 18, most of the casualties women and children.

And Washington’s message to its people in the kingdom? The US embassy in Riyadh issued another security alert urging “heightened vigilance” and warned of possible flight cancellations. Translation: the Red Sea war just moved into the departure lounge.

Look at your hands. That’s the prize. The 2026 Nobel Prize in Chemistry goes to Henri B. Kagan of Université Paris-Sud in France and Kenso Soai of Tokyo University of Science in Japan “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis,” the Royal Swedish Academy of Sciences announced Wednesday.

The riddle: many molecules, like amino acids, come in two mirror-image versions — “chiral,” like left and right hands. Life uses only one. But lab reactions usually spit out a 50-50 mix, and in medicine that matters, because one version can fight disease while the other does nothing or even causes harm, BBC News explains.

Kagan took the first decisive step in 1986, finding a way to manipulate reactions to create a bigger excess of one mirror image than anyone thought possible. Soai went further: in 1995 he described the first reaction with the potential to be homochiral, and in 2003 he pulled it off — a reaction that formed only one of the two possible mirror images. “Other than life itself, no one had previously achieved this feat,” the academy says.

“Henri Kagan and Kenso Soai have provided a solution to a chemical mystery that is over a century old: how homochirality can emerge spontaneously. The chemical reactions they have developed are spectacular,” said Heiner Linke, chair of the Nobel Committee for Chemistry. Committee member Peter Somfai called it “probably the most fundamental question in life,” adding that something like it happened four billion years ago — “and now we have, for the first time, mimicked that in the lab.”

Soai, on the phone with the Nobel press conference: “This is one of the most exciting days of my life.” Kagan was born in 1930; Soai in 1950. They split 12 million Swedish kronor — about $1.25 million, per the BBC — and the academy says their work has been decisive for chemists designing reactions to make pharmaceuticals.

Peer review, meet the firehose. OpenAI on Tuesday evening posted 722 math manuscripts, organized into 372 “families” of related results, produced by an internal frontier model the public can’t use yet, according to OpenAI’s announcement and its openai/math GitHub repository.

The numbers: over the evaluation, the model was posed about 4,000 problems. On average, each result used the equivalent of roughly three hours of ChatGPT Pro thinking compute, OpenAI says. The Decoder reports nearly every result came from a single prompt to a single agent — a far cry from last month’s Navier-Stokes claim, which took a swarm of up to 10,000 agents and millions of dollars in compute.

What’s in the pile: work across fields including number theory and algebraic geometry, and results the Wall Street Journal says touch three of the remaining Millennium Prize Problems, among them the Riemann hypothesis, per Quartz. Many — but not all — of the papers come with Lean formalizations, computer-checkable proofs, and the repository itself warns the collection “includes results at different stages of verification.”

The bold move is where it lives: GitHub, not journals. OpenAI says it consulted the Institute for Advanced Study’s Advisory Group on Mathematics and AI — but Quartz reports it broke with one request, that labs stop testing frontier math problems on proprietary models. OpenAI says it will keep doing that.

Mathematicians aren’t all cheering. In an open letter titled “A Severe Misalignment of AI in Mathematics,” 25 Fields Medal winners warned that mass-producing true statements could destroy fertile ground rather than create new ideas, The Decoder reports. OpenAI says it will fund workshops on AI-produced results and is working to “responsibly release” the model. The humans now have homework — 722 papers of it.

Happy birthday, Vladimir — here’s the body count. Russia hammered Kyiv and cities across Ukraine overnight into Wednesday with what President Volodymyr Zelenskyy called about 70 missiles, many of them ballistic, plus attack drones, in one of the biggest strikes since the full-scale war began in 2022, Al Jazeera and Reuters report. At least 20 people, including children, were killed.

The deadliest hit landed in Pryluky, in the northern Chernihiv region, where a cruise missile scored a direct hit on a five-story apartment building while residents slept. Ukraine’s State Emergency Service said 14 people were killed there, including four children, and 50 were injured, seven of them children; rescuers pulled 15 people from the rubble, Euromaidan Press reports.

“Today, for Putin’s birthday, the Russian army ‘gave’ him the destruction of an apartment building in Pryluky in Chernihiv Oblast. It was an ordinary five-story building,” Zelenskyy said. Putin turns 74 today, per the Guardian.

The rest of the map: two dead in a fire at a garage cooperative in Kyiv’s Darnytskyi district, where bomb techs also worked around an unexploded ballistic missile that fell among apartment blocks; two dead in Kremenchuk; two in Oleksandriia; damage in Dnipro and Zaporizhzhia. Ukraine’s air force said Russia launched 130 drones and 48 cruise missiles plus ballistic missiles, and that air defenses downed 161 targets. Poland scrambled jets and put ground-based air defenses on alert.

Russia’s Defense Ministry called it a “massive strike” on military-industrial sites, including where Fire Point builds Flamingo cruise missiles and long-range drones. Zelenskyy says ballistic missiles remain the biggest problem and Kyiv is hunting daily for Patriot interceptors. Foreign Minister Andrii Sybiha’s take: “On Putin’s birthday, Russian generals brought him his favorite present: war crimes.”

Brussels answered with cash: European Commission President Ursula von der Leyen announced €1.24 billion for Ukrainian drones and missiles, saying “Russia is pursuing a deliberate strategy of terror.” Translation: winter came early, and it’s armed.

The Congo outbreak just hopped a plane. Kenya confirmed its first Ebola case — and first Ebola death on Tuesday, Health Cabinet Secretary Aden Duale announced, as the outbreak in the Democratic Republic of the Congo keeps spreading, ABC News reports.

The patient was a 40-year-old Kenyan man who had lived in the DRC for seven years and traveled from Buta in the country’s northwest. After falling ill about a month ago and being treated at several DRC hospitals, he went by road to Kampala, Uganda, then flew a Jambo Jet flight into Nairobi on Oct. 3. He was isolated, tested positive for Bundibugyo virus — a rare Ebola variant behind the DRC outbreak, for which there are no vaccines and no treatments, per ABC — and died Monday evening.

Here’s the chilling part: he passed through public health screening at Jomo Kenyatta International Airport. Kenya’s health director general Dr. Patrick Amoth said medication “to lower your temperature” could mask symptoms, adding: “We believe that he knew that he was unwell.”

Now the hunt: officials have identified 28 contacts, including family and health workers, and are trying to reach 23 more passengers and four crew from his flight. “I wish to assure the public not to panic as all systems are in place to mitigate the spread of the disease,” Duale said. The World Health Organization says it is supporting Kenya’s response.

The scale next door is brutal: as of Oct. 3, the Congo Ministry of Health counted 8,854 confirmed cases and 4,114 deaths, ABC reports.

That little padlock in your browser? Somebody just counterfeited it. Google said Tuesday that attackers hijacked three country-code top-level domains — .gh (Ghana), .sl (Sierra Leone) and .as (American Samoa) — and used that control to obtain unauthorized HTTPS certificates covering “several Google domains” plus domains belonging to other organizations, according to Google’s own post.

How it worked: the attackers compromised the third-party ccTLD infrastructure and modified authoritative DNS records, Ars Technica explains. With traffic for selected sites pointed at them, they could pass the tests certificate authorities use to confirm someone controls a domain — and walk away with valid-looking certs. Google said its own systems were not compromised and it has “no reason to believe” the issuing CAs did anything wrong.

The fix so far: Chrome blocked the unauthorized certificates it identified using its emergency CRLSets mechanism, and Google worked with the issuing CAs to revoke them for other browsers. Google says Chrome users don’t need to do anything.

But here’s the gut punch, straight from Google: “Due to the complexity of DNS hijacks, we cannot guarantee that our analysis identified every affected domain, nor do Chrome interventions reliably protect non-Chrome users.” Google didn’t name the other affected brands, and Ars says it isn’t clear how many certificates were issued.

Got a website? Google’s advice is to watch Certificate Transparency logs for certs on your domains and publish restrictive CAA records naming which authorities may issue for you. History buffs will remember the 2011 DigiNotar hack, when forged Google certs were used against at least 300,000 people with ties to Iran, per Ars.

The war just came roaring back to Moscow’s doorstep. Ukraine launched more than 650 drones toward the Russian capital overnight into Tuesday, Moscow Mayor Sergei Sobyanin said — adding that most were shot down — in what Reuters calls one of the biggest attacks of the war on Moscow and the surrounding region.

The toll on the ground: Moscow region Governor Andrei Vorobyov said two people were killed — a 71-year-old man pulled from the rubble of a house and a 20-year-old man in a nearby village — and nine were injured. He said 185 drones were destroyed or brought down over his region, with 47 houses, four apartments and three cars damaged.

The big question is fuel. Prominent Russian war blogger Yuri Podolyaka said an oil storage tank was hit at the Volodarskaya oil storage and distribution facility — the biggest in the Moscow region, which stores diesel, gasoline and jet fuel and supplies all three of the capital’s large airports, per Reuters. There was no official confirmation it was hit, and Reuters could not immediately verify video purporting to show a huge blaze. Meduza reports local authorities had not reported a fire.

South of the city, the head of Domodedovo — home to Russia’s third-largest airport — said crews were working to restore electricity to villages hit by drones. Al Jazeera’s Moscow correspondent said the barrage ended a relative lull in large Ukrainian strikes on Moscow since Sept. 20, as both sides pound each other’s infrastructure ahead of winter.

Translation: Kyiv keeps aiming at the oil money that pays for Russia’s war — and the diesel squeeze is everybody’s problem now.

The Midwest just struck Nobel gold — at the bottom of the planet. The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Physics to Francis Halzen of the University of Wisconsin–Madison “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin,” per the official announcement. He gets the whole prize: 12 million Swedish kronor.

The machine is gloriously bonkers: a cubic kilometer of Antarctic ice wired with thousands of light sensors. Neutrinos zip through Earth — and you — without a trace, but very rarely one smacks an atomic nucleus and throws off a telltale flash of light the sensors can track back toward its source, the BBC explains. Halzen first pitched the South Pole idea in 1988; IceCube was finished in 2011.

The payoff: in 2013 IceCube announced the first high-energy neutrinos from outside the solar system, and it later detected high-energy neutrinos from a supermassive black hole at the heart of a distant galaxy, an active galaxy 47 million light-years away, and the Milky Way itself, UW–Madison says. “His tenacity and scientific vision has paved the way for a new kind of astronomy,” said Nobel physics committee chair Mark Pearce.

The winner kept it humble. “I have to emphasise how lucky I was. Because when we started this project, everybody realised this was maybe a good idea, but very few thought it would work, including myself,” the Belgian-born Halzen, now a U.S. citizen, told a news conference, per the BBC.

Badger bragging rights: UW says Halzen is the sixth physicist connected to the university to win the Nobel, and the first active UW–Madison faculty member to win one since Howard Temin in 1975. “This is a celebration of a very unusual project,” Halzen said.
