California Warns of Measles Exposure Across Multiple Counties After Infected Passenger Traveled by Train
California public health officials issued a measles exposure warning spanning six counties after an unvaccinated, infected passenger traveled through the state on Amtrak trains and connecting buses. The warning comes during the largest US measles resurgence in more than three decades.California health officials are warning residents of potential measles exposure across six counties after an infected and unvaccinated individual traveled through the state using Amtrak trains and thruway bus connections. Officials are urging anyone who may have been on the same routes during the relevant time periods to check their vaccination status and watch for symptoms. Measles is highly contagious and spreads through the air; a single infected person can transmit the virus to up to 90 percent of unvaccinated people they encounter. The warning comes as the United States is experiencing its largest measles resurgence in more than three decades, driven largely by declining vaccination rates in some communities. Symptoms typically appear seven to fourteen days after exposure and include fever, cough, runny nose, red eyes, and a characteristic rash. The MMR vaccine is highly effective at preventing infection. Individuals who are unsure of their vaccination status are advised to contact a healthcare provider.
Congo Begins Ebola Vaccinations for Health Workers at Center of Outbreak
Health authorities in the Democratic Republic of Congo have begun administering Ebola vaccines to health workers and frontline responders at the epicenter of the current outbreak, using the Ervebo vaccine proven effective in past outbreaks.The Democratic Republic of Congo has started an Ebola vaccination campaign targeting health workers and other frontline personnel at the center of the current outbreak. The Ervebo vaccine, which demonstrated effectiveness during previous Ebola outbreaks caused by the more common Zaire strain of the virus, is being used in the campaign. Health workers and others directly involved in the outbreak response are being prioritized for the initial doses. Congo has faced repeated Ebola outbreaks in recent years, and vaccination of frontline responders is considered a critical early step in containing spread. The current outbreak's scope and the specific region affected were not fully detailed in available source material, but the initiation of targeted vaccination represents a formal escalation in the public health response.
Study Finds US Military Veterans Have Higher Levels of PFAS 'Forever Chemicals' Than Civilians
A peer-reviewed study found that US military veterans carry significantly higher concentrations of PFAS 'forever chemicals' in their blood than the general civilian population, linked to elevated PFAS contamination around military bases from firefighting foam.A new peer-reviewed study has found that US military veterans have substantially higher levels of per- and polyfluoroalkyl substances — known as PFAS, or 'forever chemicals' — in their blood compared to civilians. The elevated exposure is linked to PFAS-containing firefighting foams historically used at military installations, which have contaminated soil and water around bases across the country. PFAS compounds are called 'forever chemicals' because they do not break down naturally in the environment or the human body and have been associated with a range of health concerns including certain cancers, immune system effects, and thyroid disruption. The findings raise additional questions about the long-term health consequences for veterans who served at or near affected installations, and about the adequacy of existing medical monitoring and compensation programs for PFAS-exposed service members. Efforts to clean up PFAS-contaminated military sites have been ongoing, though progress has been slow and costs are substantial.
Fiji Declares National HIV Emergency as Cases Surge
Fiji has declared a national emergency over a dramatic rise in HIV infections, with an estimated one in 60 adults now living with the virus. Authorities link the surge to increased drug use and needle sharing.Fiji has declared a national public health emergency in response to a sharp increase in HIV infections. Approximately one in 60 adults in the Pacific island nation is now estimated to be living with the virus. Health authorities recorded around 2,000 new cases in 2025 alone — a dramatic rise for a country of Fiji's size. Officials attribute the surge primarily to growing intravenous drug use and the sharing of needles, which enables rapid transmission. Fiji is a popular international travel and tourism destination, including for American visitors. The government's emergency declaration is intended to unlock additional resources and accelerate the public health response, including expanded testing, treatment access, and harm reduction programs. HIV is manageable with antiretroviral treatment, but access to consistent medical care is a challenge in many Pacific island nations. The declaration signals that existing health infrastructure has been insufficient to contain the spread.
Trump Announces Plans for 'AI Force' and Appointment of Artificial Intelligence Overseer
President Trump announced he would create an 'AI Force' to monitor artificial intelligence and appoint an AI overseer, providing few specifics. The announcement follows growing public debate about the risks of advanced AI systems.President Trump announced plans to establish a new entity called the 'AI Force' dedicated to monitoring artificial intelligence, and said he would soon appoint an AI overseer — described in some accounts as an 'AI czar' — to lead oversight efforts. Trump provided few details about the structure, authority, or funding of either initiative. The announcement drew comparisons to Trump's first-term creation of the Space Force, a branch of the military established in 2019. The timing coincides with a period of heightened public and industry debate about the risks posed by advanced AI systems. Trump also stated that his administration would not impede the growth of the AI industry, framing the initiative as protective of American technological leadership rather than restrictive. The announcement is consistent with the administration's broader position that slowing AI development would cede ground to China. Whether the AI Force would be a formal military branch, a regulatory body, or an advisory office was not specified in available source material.
National Park Service Budget Cuts Delay Maintenance Projects Across the Country
Budget reductions and staff cuts at the National Park Service have deferred maintenance projects at parks across the United States, while resources have been redirected to presidential priority projects in Washington.The National Park Service is facing deferred maintenance projects at parks around the country as a result of budget cuts and staffing reductions under the Trump administration. Resources have been diverted from routine park upkeep to support projects in Washington favored by the president. The practical effects include postponed infrastructure repairs at parks that were already carrying a significant maintenance backlog — estimated at tens of billions of dollars in deferred work prior to the current round of cuts. The redirection of funds and personnel raises questions about the long-term condition of federal lands and visitor facilities. The National Park Service manages more than 400 sites across the country, including national parks, monuments, historic sites, and recreation areas visited by hundreds of millions of people annually.
Houthi Forces Strike Near Riyadh Airport; Saudi Arabia Reports Missile Intercept
Yemen's Houthi movement launched ballistic missiles and drones targeting Riyadh and Saudi oil facilities. Saudi Arabia reported intercepting a missile aimed at the capital, while a fire broke out near Riyadh's airport, causing flight delays.Yemen's Houthi movement launched a wave of ballistic missiles and drones at Saudi Arabia's capital Riyadh and at Saudi oil infrastructure, representing a significant escalation in the conflict. Saudi authorities sent air raid alerts to citizens by mobile phone warning of aerial attacks. A fire broke out near a fuel depot at Riyadh's international airport, visible as thick black smoke rising above the area, and caused flight disruptions. Saudi officials said they intercepted at least one ballistic missile aimed at the capital. The extent of damage to oil facilities was not immediately confirmed across all sources. The attack marks one of the most direct Houthi strikes on the Saudi capital in recent memory. The Houthis, an Iranian-backed armed group that has controlled much of northern Yemen for years, have continued launching cross-border attacks despite years of Saudi-led military operations. The conflict carries implications for global energy markets, as Saudi Arabia is one of the world's largest oil exporters, and for shipping through nearby waterways. Pakistan, which signed a joint defense pact with Saudi Arabia last year, may face pressure to respond to the escalation.
Anthropic Moves Forward with IPO Plans as AI Safety Debate Intensifies
AI company Anthropic is advancing plans for an initial public offering, with annualized revenue expected to reach $100 billion this year. Its chief executive has simultaneously called for slowing development of certain advanced AI models.Anthropic, the AI safety-focused company behind the Claude AI assistant, is moving ahead with plans for an initial public offering even as its chief executive, Dario Amodei, publicly advocates for slowing the development of some advanced AI models. The company is expected to reach $100 billion in annualized revenue in the current year, reflecting rapid commercial growth. Amodei has been one of the more prominent voices in recent weeks calling for greater oversight and caution around powerful AI systems, including advocating for independent evaluators embedded within AI companies. The juxtaposition of pursuing a major public market listing while simultaneously urging restraint on AI development has drawn attention and scrutiny. Anthropic was founded by former OpenAI researchers and has positioned itself as focused on AI safety research alongside commercial development.
Lawsuit Alleges Leading AI Companies Made Illegal Agreement to Coordinate Development Slowdown
A lawsuit filed against Anthropic, OpenAI, SpaceX AI, and Google alleges the companies violated antitrust law by coordinating an agreement to slow AI development, which plaintiffs argue harms consumers who pay for AI subscriptions.A lawsuit has been filed alleging that four of the leading artificial intelligence companies — Anthropic, OpenAI, SpaceX AI, and Google — entered into an illegal agreement to coordinate a slowdown of AI development, in violation of antitrust law. The plaintiffs argue that this coordination among competitors constitutes anticompetitive behavior and that it reduces the value consumers receive from paid AI products and subscriptions. Antitrust law generally prohibits competing companies from coordinating on matters that affect market competition. The case draws on the recent public statements by executives at these firms calling for pauses or slowdowns in certain AI development, and alleges those public statements reflect a private agreement rather than independent decision-making. The lawsuit adds a new legal dimension to the already contentious debate over how quickly advanced AI systems should be developed and who should set the pace.
