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.

The red stuff is coming out of the barn. President Donald Trump signed an executive order Monday night to temporarily allow off-road “dyed” diesel for highway use and defer the federal excise tax on it, according to the White House fact sheet.

Trump unveiled it at a rally in Nebraska, NBC News reports: “Tonight I’m going to sign a historic executive order to officially waive the off-road requirement and allow anyone to purchase tax-free red dye diesel for any reason.” The White House claims it will save truckers over $100 per refill.

The fine print, straight from the order itself: within five days, Treasury must decide whether relief is authorized under a federal tax-deadline relief statute (26 U.S.C. 7508A) and, if so, defer the tax on dyed diesel used on the road from Oct. 5 through Dec. 31, 2026 — without penalties or interest — and have the IRS announce it won’t impose dyed-fuel penalties for that period. Treasury is told only to “explore avenues, including legislation,” to wipe out the deferred bill. States get a nudge, not a mandate: the White House will “encourage” them to adopt matching policies.

Why now? Pain at the pump. NBC says diesel hit an all-time high of $6.52 a gallon on Sept. 22, per AAA, and is up more than 70% since the Iran war began Feb. 28 — with Ukrainian drone strikes on Russian refineries pushing the Kremlin to ban diesel exports. Voters in both parties are citing gas prices and the cost of living as top midterm issues.

Wall Street noticed: CNBC says stock futures rose Tuesday morning as Treasury yields and oil prices both dropped. Farmers, truckers and anybody with a diesel tank: watch for that Treasury guidance — and your state’s rules — before you fill up red.

The Black Sea war just crashed into NATO’s front yard. Bulgarian Prime Minister Rumen Radev said two commercial vessels were struck by drones Tuesday inside Bulgaria’s Exclusive Economic Zone — the first attack on shipping in the NATO member’s EEZ, the Associated Press reports via CBC.

Radev said sea and aerial drones hit the ships around 3 a.m. local time, about 80 miles (128 km) off the coast. The Togo-flagged Alfa Watan suffered critical structural damage and sank at the scene. The BBC says a nearby Bulgarian vessel found only an overturned boat, rafts and life jackets; the crew is missing and a search is under way.

The second ship, the Palau-flagged Able, was carrying grain and caught fire. A Bulgarian ferry pulled all 18 crew to safety — 11 Turkish and seven Indian nationals — and two badly injured sailors were flown to a hospital in Varna. “This is an unacceptable attack in Bulgaria’s exclusive economic zone. It is a blatant violation of international law and maritime law,” Radev said.

Who did it? Officially, nobody knows: the origin of the drones was not immediately established, NATO declined to comment, and the BBC says Moscow has not commented. But the timing is ugly — a day earlier a Turkish-owned cargo ship carrying corn caught fire after a drone attack and sank off Romania, killing two, in what Ukraine’s Volodymyr Zelenskyy called “a horrific strike by two Russian drones on a civilian vessel.”

And the bill lands on everyone. “What is happening is seriously disrupting shipping in the Black Sea, driving up insurance costs even further and making shipping extremely difficult,” Radev warned. EU Commission President Ursula von der Leyen put it bluntly: “Attacks on civilian shipping are unacceptable.”

The fight for one of the planet’s most important shipping lanes just went full throttle. Forces of the Saudi-led coalition recaptured several key areas around the Bab el-Mandeb Strait from Iran-backed Houthi rebels on Monday, Yemeni officials told the Associated Press.

Government-allied forces retook the crucial town of Dhubab just north of the strait and also captured Bab and Hadeid, officials said; witnesses saw government tanks rolling in. Coalition spokesman Maj. Gen. Turki al-Malki said 100 fighter jets were backing the offensive, that the coalition had secured “air protection” of the strait, and that it had destroyed hundreds of Houthi targets.

Yemen’s Presidential Leadership Council chief Rashad al-Alimi branded the operation “Yemen Dawn” and said the goal is “liberating” rebel-held Sanaa. The Houthis reported multiple coalition airstrikes, including on the capital. The push came right after the rebels seized the town of Turbah on Sunday, cutting a main road between Taiz and Aden.

Washington’s fingerprints? Secretary of State Marco Rubio said the Saudis “have a right to defend themselves” but wouldn’t detail coordination. A regional official and a U.S. official told AP that U.S. support included intelligence sharing, target identification and planning for the offensive.

Why you should care: the Houthis’ September land grab — including the city of Mokha and several Red Sea islands — gave them the Yemeni side of a chokepoint that carries 12% of global trade. The flare-up since mid-July has killed at least 959 people and wounded more than 4,200, per the WHO, and displaced about 174,097 people inside Yemen, per the U.N. migration agency.
