Saudi Crown Prince Mohammed bin Salman met Egyptian President Abdel Fattah Al-Sisi in Cairo on Tuesday for a working visit covering regional security, trade and the wars in Gaza, Sudan and Yemen. Egypt's presidency said the two leaders agreed that the security of Saudi Arabia and the Gulf states is part of Egypt's national security. Both stressed the need to protect freedom of navigation through the Strait of Hormuz, Bab Al-Mandab and the Red Sea, where shipping has been disrupted for months. They also agreed to speed up steps to raise bilateral trade and investment and to remove obstacles that limit economic ties.

The US Supreme Court late on Monday rejected the Trump administration's plan to give the Postal Service a central role in deciding who can receive a mail ballot, clearing the way for normal mail voting in the November 3 midterms. The 7-2 ruling followed a months-long legal fight and a second federal judge's order blocking the same rules. The plan would have required states to adopt a uniform ballot envelope and upload lists of eligible voters to a federal portal, and the Postal Service could have refused to deliver ballots that failed its checks. A whistleblower report warned millions of ballots might never have been sent.

The 10-year US Treasury yield rose above 5% on Monday for the first time in nearly three years, as energy prices tied to Middle East supply disruptions kept inflation pressure high. The Federal Reserve meets on September 15-16, and traders now price roughly an 80% to 90% chance of a rate increase, up sharply from a week earlier. Goldman Sachs chief economist David Mericle wrote that pricing is high enough that the committee will likely want to avoid the market reaction that would follow from holding steady. Asian shares and US stocks fell as investors weighed higher oil, higher yields and slower AI spending.

US President Donald Trump dismissed concerns about artificial intelligence safety as a hoax in posts on social media, rejecting calls for more guardrails on the technology. His comments followed an interview in which Anthropic co-founder Jack Clark told the BBC that a mandatory AI kill switch, verifiable by a third party, may eventually be needed. Clark said AI systems are becoming more capable every few months. The exchange highlights a deadlock in Congress over frontier models, data center construction and the electricity those sites consume, while demand for AI memory and accelerator chips keeps rising.

The TAME trial, the planned study of whether the diabetes drug metformin can delay diseases of aging, has still not launched because it remains short of funding. It is designed as a six-year randomized trial of about 3,000 adults aged 65 to 79 at 14 US sites, coordinated at Wake Forest, and is estimated to cost $45 million to $70 million. The National Institute on Aging has set aside about $5 million. Researchers say the obstacle is that metformin is a cheap generic, so no drugmaker expects a return. Claims that the trial has enrolled patients or produced results are inaccurate.

The Trump administration said on Monday it will repeal rules limiting greenhouse gas emissions from coal and gas power plants, and the EPA proposed rolling back its own authority to regulate that pollution in the future. Power plants are the second-largest source of US climate pollution, close to a quarter of the national total and roughly 3% of the global figure. The agency argues the rules threatened grid reliability as electricity demand rises from data centers. Environmental groups and law professors said the move will increase emissions in a year on track to be the warmest on record.
