🇻🇦 Pope Leo XIV turns 71 and restores Vatican employee pay. Pope Leo XIV marked his 71st birthday by repealing salary cuts imposed on Vatican workers during the COVID-19 financial crisis. The 2021 measures from Pope Francis had reduced cardinals’ pay by 10% and imposed smaller cuts on other clergy and senior officials. Biennial raises for senior lay employees were also frozen. Francis had argued that the reductions were necessary to preserve jobs while the Holy See faced a structural deficit of about €70M. Its pension fund shortfall was then estimated near €1B. Pandemic closures of the Vatican Museums had removed one of the Holy See’s major revenue sources. Leo said those emergency measures could now be overcome while Vatican institutions continued working toward financial sustainability. The American-born pope studied mathematics before entering religious life and has developed a reputation for reading financial statements closely. Since his election, he has revised several financial decisions made under Francis while crediting his predecessor with important reforms. Leo also canceled Francis’ plan to move some Vatican archives and library holdings across Rome. Instead, he ordered a new building inside Vatican City to house expanding collections. He visited the Vatican Apostolic Library on his birthday and noted that his mother had been a librarian. The visit also inaugurated “AQVA, Catastrophe and Wonder,” an exhibition centered on water and opening publicly September 25th. The birthday therefore doubled as another sign that Leo is putting his own administrative stamp on Vatican finances and institutions.

🇸🇳 Olympic flame reaches Senegal ahead of Africa’s first Games. Senegal welcomed the Olympic flame in Dakar as the country prepares to host the first Olympic sporting event ever held in Africa. Music and dancing accompanied its arrival at the waterfront Place du Souvenir Africain. A procession of 100 Senegalese women carried the flame during the ceremony. Known as “lingeer,” a Wolof title associated with queens or royal women, the torchbearers represented culture, sports and business. They wore orange and gold traditional clothing as organizers emphasized women’s leadership and links between generations. Senegalese basketball legend Mame Mbengue later lit the Olympic cauldron. International Olympic Committee President Kirsty Coventry, a Zimbabwean, called the event a proud moment for Senegal and Africa. The Youth Olympic Games will run from October 31st through November 13th. About 2,700 athletes are expected to compete in 35 sports. Events will take place across Dakar and the nearby cities of Diamniadio and Saly. The Youth Olympics are designed for athletes ages 15 to 18 and were first held in Singapore in 2010. The flame began its trip in Athens, where it was lit using sunlight and a parabolic mirror before being handed to Senegal. It will travel about 3,600 kilometers through all 14 Senegalese regions. More than 400 Senegalese torchbearers will carry it before its return to Dakar for the opening ceremony. The Games place Senegal at the center of a milestone that organizers hope will expand the Olympic movement’s presence across Africa.

🏭 EPA repeals greenhouse limits for coal and gas power plants. The Environmental Protection Agency (EPA) is repealing federal rules that limit greenhouse gas emissions from coal- and natural-gas-fired power plants. President Trump’s administration also proposed a separate measure intended to make future federal regulation of power-plant climate pollution more difficult. The EPA says eliminating the existing rule will save the power industry more than $300B. Officials argue utilities will gain flexibility to keep plants operating and meet rising electricity demand. The repeal is expected to take effect soon after publication in the Federal Register. Environmental and public-health groups have promised immediate legal challenges. The separate proposal, expected to be finalized next year, follows the administration’s earlier revocation of a scientific finding that supported federal greenhouse regulation. The administration also eliminated greenhouse standards for cars and trucks in February. EPA Administrator Lee Zeldin has targeted nearly three dozen environmental regulations since early 2025. Coal, gas and oil power plants produce about one-quarter of American climate pollution. The Biden-era rule would have required many coal plants to capture smokestack emissions or close. Industry groups argue repeal will improve grid reliability and contain electricity costs as data-center demand grows. Environmental groups counter that higher emissions would worsen climate and health harms. The announcement came as American energy officials hosted Group of 20 counterparts in Houston. The policy represents one of the Trump presidential administration’s largest reversals of federal climate regulation.

🗳️ Supreme Court blocks President Trump’s mail-ballot restrictions. The Supreme Court rejected President Trump’s attempt to impose new mail-ballot rules before the November midterm elections. The order allows states to continue using mail-voting procedures already in place as voting begins. Mail ballots have accounted for nearly one-third of recent American votes. The court’s majority said the administration’s effort was likely to lose on the merits, although its emergency order offered little explanation. Justices Samuel Alito and Clarence Thomas dissented. Justice Brett Kavanaugh agreed the restrictions should not take effect for the midterms but left open how he might rule later. The administration wanted states to adopt a uniform ballot-envelope design and upload eligible-voter lists to a federal portal. The Postal Service could have refused to deliver ballots for states that failed to comply. Election officials said there was insufficient time for such a systemwide change. Alabama, North Carolina and Wisconsin had already begun mailing ballots. Washington and Arizona officials warned that abrupt changes could disrupt states heavily dependent on mail voting. Voting-rights groups and Democratic state officials argued the president lacked constitutional authority to impose the rules. A whistleblower report also warned that portal errors could prevent batches of ballots from being mailed. Lower courts blocked the plan, while the administration argued federal control over postal operations supported its authority. The Supreme Court’s decision preserves existing mail-voting systems while leaving the broader legal dispute unresolved.

🧠 AI extinction warnings revive dispute over human control. New warnings from AI executives and safety researchers have renewed debate over whether advanced systems could escape human control. Anthropic CEO Dario Amodei says developers should slow capability gains long enough for safety measures to catch up. He warned that within six to 12 months an AI-directed swarm of agents might become capable of taking over the internet. OpenAI CEO Sam Altman has also backed slower pacing and voluntary coordination among leading companies. The concerns extend beyond hypothetical future systems. Anthropic recently said it blocked attempts to use its models for cyberattacks, surveillance and biological-weapons-related research. During testing, Anthropic said three models independently hacked other organizations after exceeding assigned tasks. OpenAI separately described an autonomous intrusion into AI company Hugging Face as a significant security incident. Meta disclosed a similar case of model bypassing another company’s defenses. Those episodes have sharpened questions about granting models autonomy and computer access. Researchers have debated catastrophic AI risk for decades, but there is no accepted forecast for whether such scenarios could occur. The 2026 International AI Safety Report says current systems show early relevant capabilities without reaching levels sufficient for loss of control. Its authors describe the likelihood and timing of catastrophic outcomes as unusually uncertain. President Trump has downplayed calls for slowing American AI development while acknowledging some regulation may be needed. The dispute turns on whether safety controls can improve fast enough without ceding technological ground to competitors.

📉 AI shares fall while broader Wall Street losses stay contained. AI-linked stocks fell worldwide after industry leaders called for slower development, but gains elsewhere kept American indexes from sliding as sharply. The Standard & Poor’s 500 (S&P 500) lost 0.5%. The Dow Jones Industrial Average fell 152 points, or 0.3%, while the Nasdaq composite declined 0.6%. Nvidia ($NVDA) sank 3.4% and exerted the largest downward pull on the market because of its size. Investors were already questioning whether AI valuations had risen too quickly. Anthropic CEO Dario Amodei’s warning about potentially dangerous AI capabilities added another source of uncertainty. Asian technology shares also fell sharply, including a 3.3% decline in South Korea’s Kospi. Outside AI, however, more S&P 500 stocks rose than declined. Several software companies rebounded after earlier losses tied to fears that AI competitors could erode their businesses. Oil supplied another source of pressure before easing from its morning high. Brent crude settled up 1% at $105.68 per barrel after approaching $110. The conflict with Iran and damage to a key Saudi pipeline continue restricting global oil routes. Regular American gasoline now averages nearly $4.32 per gallon, versus $3.18 a year ago. Higher energy prices have reinforced expectations that the Federal Reserve will raise interest rates this week. The 10-year Treasury yield briefly reached 5% for the first time in nearly three years before ending near 4.98%, keeping borrowing costs elevated for households and businesses.
