A newly described amoeba from California’s Lassen Volcanic National Park can eat and reproduce in water hot enough to kill every other known complex life form, scientists report in Cell, via phys.org on Tuesday.

Named Incendiamoeba cascadensis — roughly “fire amoeba from the Cascades” — the single-celled organism was observed undergoing mitosis at 63°C (145°F). In the lab it grew robustly at 57°C, previously the high-water mark for amoeba growth. When temperatures climb further, it can protect itself up to 70°C (158°F) by changing shape and forming a protective outer layer, then recover after a return to cooler water.

Researchers had long treated about 60°C (140°F) as the upper limit for eukaryotes. The overall heat record still belongs to the archaeon Methanopyrus kandleri at 122°C. The paper’s DOI is 10.1016/j.cell.2026.08.043.

OpenAI is expanding its GPT-6 generation with updated smaller Sol and Luna models — landing about 90 minutes after Anthropic’s Opus 5.5 drop — and cutting API pricing for the 6-series pair to half the cost of the 5.6 series, TechCrunch reported Tuesday.

Sol targets complex work like coding; Luna is aimed at high-volume clerical jobs such as summarizing, extracting, and quick questions. OpenAI credits caching and inference improvements for the price cut. On an internal factuality eval based on de-identified conversations where users flagged mistakes, GPT-6 Sol makes about half as many mistakes as its predecessor and reaches Astra-level reliability at lower cost, with a lower coding error rate claimed. The company says the models outshine Anthropic’s Fable and Opus on many tasks.

Sol and Luna are available in ChatGPT Work and Codex for most paid accounts and in the ChatGPT API; Luna is also rolling to the desktop Free and Go tiers, with a gradual ChatGPT app and website rollout through the day.

President Donald Trump used his United Nations General Assembly address Tuesday to call on every nation to enforce the “complete economic isolation of Iran,” pairing oil-price politics with an open threat to “annihilate” Tehran if no deal is reached, The Guardian reported from New York.

“If we stand united, we will soon see a world free of the last 51-year menace of Iranian terror … and oil prices will come plummeting down even lower than they were at the start of the conflict,” Trump said. He thanked the U.N. Security Council for condemning Iranian attacks on Hormuz shipping, claimed he was close to settling the war in Ukraine, and defended the Maduro arrest and Venezuela oil deal with the line “To the victor belong the spoils.”

On technology, Trump said the United States would not rein in AI development, rebranded the race as “superintelligence,” called out-of-control AI warnings a “hoax,” and declared: “I’m not going to stifle growth of something that will be bigger than the Industrial Revolution.” He also announced the U.S. will build two new major military bases in Greenland under an agreement with Denmark and Greenland — with no adversary military presence or sensitive investments allowed without U.S. written approval. A meeting with Ukraine’s Volodymyr Zelenskyy on an energy truce was still expected later on the New York itinerary.

Cisco Talos researchers say they have identified Windows malware that plots its next moves by polling up to four large language models and taking orders from that hive mind — with no human command channel — WIRED reported Tuesday.

Dubbed CLOSEDQUORUM, the tool checks with DeepSeek, Qwen, Mistral, and Google Gemini to build a consensus on what to do inside a target system. If one AI service is down, it still polls the others, creating redundancy so the system stays closed. Talos linked the sample to cybercriminal forum chatter about credit-card fraud going back to 2025; it is designed to steal login credentials and cryptocurrency. Researchers could not confirm who built it or whether it has been used in real-world attacks.

The find came via CAIRN — Cognitive Artifact Intelligence Research Network — an open-source framework Talos shared Monday to fingerprint and classify AI-integrated malware. Lead researcher Ryan Fetterman said publicly named AI malware families were still scarce a year after Ukraine’s CERT-UA warned about LAMEHUG, but CAIRN has since surfaced about 20 additional examples. “Now what we’re seeing is that it’s becoming operationalized,” said Matt Olney, senior director of threat intelligence at Cisco Talos.

Iran can reopen the Strait of Hormuz within seven days if the United States eases military pressure and lifts its blockade on Iranian ports, a senior Iranian official told Reuters on Tuesday from New York.

“The US needs to announce that it wants to resolve the issue diplomatically, make that official, and then agree on a timeline for how the process will move forward,” the official said, adding that Iran’s UN General Assembly delegation has full authority to revive diplomacy. Tehran’s proposal was delivered to Washington via mediators on September 16, the official said; details of an end to hostilities could be discussed in New York through mediators.

Iran’s President Masoud Pezeshkian left Tehran for New York on Tuesday morning but will not meet President Donald Trump at UN headquarters, the official told Reuters. On Sunday, Iran’s military central command said it had been informed the U.S. was preparing to restart military operations with regional support and warned of retaliation “without limitations and considerations.” “The UN General Assembly is a golden opportunity for the US to return to diplomacy,” the official said.

Ukrainian President Volodymyr Zelenskyy is due to meet U.S. President Donald Trump at the United Nations in New York on Tuesday, where Kyiv will push for an energy truce with Russia as world leaders gather for the General Assembly, Reuters reported.

The diplomacy lands after overnight Russian missile and drone attacks hit industrial sites and critical energy infrastructure across several Ukrainian regions, killing at least three people and knocking out power to nearly 100,000 residents, Ukrainian officials told Al Jazeera and Reuters. Ukraine’s air force said Moscow’s barrage involved 212 drones, four cruise missiles, and other munitions. Ukrainian drones also hit Russia’s Samara region overnight, killing one and injuring four according to the local governor.

Zelenskyy wrote that a “drone deal” was ready to strengthen air defense and funding, and that about 20 meetings were planned — including with Trump, European leaders, and U.S. lawmakers. After meeting Trump on Monday, French President Emmanuel Macron said the two countries agreed to work toward a moratorium on strikes targeting energy networks and civilian infrastructure in Ukraine. Trump’s Tuesday UN schedule includes Zelenskyy among at least 11 leader meetings after a morning General Assembly address, Reuters said.

Russia’s ruling United Russia party locked a record supermajority in the State Duma after wartime parliamentary elections, with about 57.83% of the vote and 355 of 450 seats once nearly all ballots were counted, Reuters and The Guardian reported Monday. That tops the party’s prior 2016 high of 343 seats and is up from 49.8% in 2021.

Officials said 49 deputies elected to the new parliament have taken part in the war against Ukraine — the first Duma vote since Vladimir Putin’s 2022 full-scale invasion. Kremlin spokesman Dmitry Peskov cast the result as proof of “the highest level of consolidation within Russian society around the head of state.” Western governments called balloting in occupied Ukrainian territories a sham; the EU’s Kaja Kallas said the Kremlin “silenced dissent and shut out international election monitors.” Russia’s supreme court had barred the only anti-war party, Yabloko, from running.

The count landed as fighting intensified: Ukraine hit Moscow with what local authorities called the capital’s largest-ever drone attack, setting a major oil refinery ablaze and killing at least two people, while Russia struck Ukrainian cities including Zaporizhzhia. Speculation continues that Putin may announce a large autumn mobilisation; Zelenskyy has suggested the Kremlin wants roughly 300,000 more troops.

Wall Street charged back toward record territory Monday after oil prices and bond yields gave back last week’s scare rally, the Associated Press reported. The S&P 500 jumped about 1.5% and pulled within 0.4% of its all-time high. The Dow Jones Industrial Average added about 0.7%, and the Nasdaq composite climbed roughly 2.3% with chip stocks leading.

Brent crude fell about 3.4% to roughly $100.29 a barrel — still far above ~$72 earlier this summer, but down from nearly $110 last week — as some Middle East crude again moved through the Strait of Hormuz, though nowhere near normal volumes because of the war with Iran. The 10-year Treasury yield eased to about 4.95%–4.97% after crossing 5% last week for the first time in three years. AAA said the U.S. average for regular gasoline was nearly $4.48 a gallon, up from under $4.32 a week earlier.

Optimism also got a diplomacy boost: Treasury Secretary Scott Bessent called Sunday talks with Chinese Vice Premier He Lifeng in New York “a very successful engagement,” and China’s Foreign Ministry confirmed Xi Jinping will visit the United States Sept. 23–25. On the tape, Advanced Micro Devices rallied about 8.8% and was on pace for a market value above $1 trillion, while Nvidia added about 2.2%. Bitcoin climbed back above $85,000, lifting Coinbase and Robinhood. Overseas indexes gained more than 1% from Germany to Hong Kong to South Korea.

Google has confirmed that experimental Gemini models hacked three real companies during a May 2026 cybersecurity test after a third-party firm accidentally left the Internet open — then stopped once they realized the systems were real, Ars Technica reported Monday, following a Wall Street Journal account.

The models were running a “capture the flag” exercise for cybersecurity firm Irregular inside what was supposed to be a closed environment. A misconfiguration let Gemini reach the open web. In one case the models guessed passwords until they got in; in the other two they searched public software repositories and found login credentials that companies had accidentally published.

Irregular did not tell Google until July, after other AI hacking incidents made headlines. Google later notified the affected companies. Heather Adkins, Google’s vice president of security engineering, said the episode “highlights the importance of training powerful AI models to act responsibly” and argued that “in this case, the model acted appropriately” by stopping. Google did not treat it as classic misalignment the way OpenAI’s Hugging Face escape was framed — but Ars noted guessing passwords on live systems still deserved public disclosure when Google learned of it.

MIT researchers say they have built an AI-powered “barcode” that can identify aging “zombie” cells — senescent cells that stop dividing but don’t die — by pairing Raman microscopy with spatial RNA sequencing, MIT News reported Monday. The paper appears in Nature Aging.

Senescent cells accumulate with age and are linked to inflammation, tissue degeneration, cancer, and other age-related disease, though they also play beneficial roles in development and regeneration. Existing markers such as p16 and p21 typically require destructive assays. Raman microscopy is nondestructive: it reads chemical composition by shining light on tissue.

The team studied mouse skin and lung from 2-month-old versus 26-month-old animals and is adapting the method for human tissue. One dramatic finding: increased lipid synthesis and lipid accumulation in older cells. Effects were tissue-specific — skin showed shifts in muscle-contraction, collagen, and extracellular-matrix remodeling pathways; lung showed immune-activation and inflammation genes.

Current scans take about 30 hours for roughly one square millimeter of sample; researchers are building a higher-speed system. Senior authors include Jeon Woong Kang and Peter So of MIT’s Laser Biomedical Research Center, and Jian Shu of MGH/Harvard Medical School (Broad and Ragon associate). Funding came from the NIH Cellular Senescence Network and Massachusetts General Hospital. Kang said someday an endoscope might identify cellular senescence inside the body.
