President Donald Trump said on Monday that he would join a three-way meeting with Russia's Vladimir Putin and China's Xi Jinping, but that the talks would focus on nuclear weapons rather than the war in Ukraine. The Kremlin said the idea came up in recent discussions, and next month's APEC summit in Shenzhen has emerged as a possible venue. No meeting has been fixed. Trump also renewed criticism of Ukraine's Volodymyr Zelensky, saying it was time for someone else to negotiate on Ukraine's behalf. A joint meeting of the three leaders would be unprecedented.

Federal agents arrested more than two dozen people in California on Monday in a push against noncitizen voting, with the Guardian reporting that 28 green card holders were charged. Homeland Security Investigations officers carried out the operation in Commerce, southeast of Los Angeles, as part of what the Justice Department calls Operation Protect the Vote. The arrests came as the administration asks a federal court to block California from counting mail ballots from about 20,000 voters it calls likely noncitizens before the November 3 midterms. State officials call the lawsuit interference in a state election.

China's exports rose 36.3 percent in September from a year earlier to $447.18 billion, the fastest growth since February and well above forecasts of 25.5 percent. Electronics and semiconductors led the gain, driven by demand for data-centre parts as companies expand AI computing capacity, and car shipments also climbed. Imports rose 31 percent, but the monthly trade surplus still reached a record $133.5 billion. Exports to the United States rose 39.6 percent after Washington and Beijing agreed to roll back tariffs on $30 billion of goods each and extended their trade truce to January.

Samsung will build the base dies for Nvidia's custom high-bandwidth memory, NVHBM, on TSMC's 3-nanometer process rather than its own foundry, according to the Seoul Economic Daily. Industry estimates put TSMC's 3nm yield above 90 percent against roughly 60 percent for Samsung's 2nm line. The design moves the memory controller onto the base die, freeing GPU space and delivering up to 30 percent more bandwidth and 15 percent less power than HBM4E. It would be the first time the two foundry rivals have worked together on HBM, and it comes as UBS projects a 10 percent global HBM shortfall next year.

Japan launched its Martian Moons eXploration spacecraft on Tuesday aboard an H3 rocket from Tanegashima, aiming to return the first samples from Phobos. Liftoff was at 4:41 a.m. local time. The 4,480-kilogram probe will spend about three years in the Martian system, mapping both moons and then landing on Phobos to collect at least 10 grams of material. A capsule is due back on Earth in 2031. Scientists hope the samples will show whether the moons are captured asteroids or debris from an impact on Mars.

Drew Rasmussen held Cleveland to one run on four hits over seven innings as the Tampa Bay Rays beat the Guardians 3-1 in Game 5 of the American League Championship Series, taking a 3-2 lead. Rasmussen is the first Rays pitcher with two postseason starts of seven or more innings allowing one run or fewer. Cleveland managed five hits and its defence again failed to convert a playable out. Game 6 is at Tropicana Field on Tuesday. The Guardians, who have not won a title since 1948, came back from 0-2 down in the Division Series.

A Harvard Medical School study published in Nature Medicine found that people at risk of Alzheimer's who walked 3,000 to 5,000 steps a day had about 40 percent less cognitive decline than those who walked less, a delay of roughly three years. Those walking 5,000 to 7,500 steps appeared to gain as much as seven years. Brain scans showed less buildup of tau, a protein tied to disease progression. The study followed participants for about nine years but is observational, so it cannot prove that walking caused the difference.

A study in Nature Communications finds that Thwaites Glacier in West Antarctica could add up to 30 millimetres to global sea level by 2100, roughly twice earlier estimates, even without additional warming. The revised figure accounts for warm seawater reaching several kilometres inland beneath the glacier's floating front, a process most ice-sheet models left out. Thwaites already loses more ice each year than snowfall replaces, and its bed deepens inland. The finding changes flood frequency estimates for coastal cities, ports and roads built near present high tide lines.
