OpenEvidence and Anthropic Make a Clinical-Evidence AI Free to Clinicians in About 100 Lower-Income Countries
OpenEvidence, a platform that answers doctors' questions from peer-reviewed research and treatment guidelines, announced with Anthropic on September 23 that a specialised version will be free to healthcare providers in about 100 low- and middle-income countries, including Uganda, Angola, Sudan, Haiti and Mongolia. Anthropic supplies the models; OpenEvidence says it will tailor the system to each region's health infrastructure. The existing product is already free to clinicians in the US and Europe, where US doctors consulted it 42 million times in August alone. Anthropic president Daniela Amodei said market incentives alone "would not cause it to happen." Why it matters: A tool with proven heavy use in rich-country medicine is moving, at no cost to the clinician, into health systems where access to major journals, specialist expertise and continuing medical education is scarce, and at the scale of about 100 countries at once rather than a pilot. No per-country launch dates or clinician-verification process have been published, and it is not yet shown which guidelines the system follows where national protocols differ from US ones.
MTN and the Gates Foundation Commit $25 Million to AI and Phone-Based Maternal Care for 500,000 Nigerian Women
The MTN Group Foundation and the Gates Foundation launched the Nigeria Maternal Health Multiplier on September 22: about US$25 million in direct and in-kind contributions over 2026 to 2030. Targets are 500,000 women reaching better care by 2030, 5,000 frontline health workers equipped with AI and phone-based decision support to spot pregnancy and childbirth complications earlier, and 500 facilities connected to more consistent care standards. MTN contributes connectivity, affordable smartphones, mobile data, mobile financial services and local execution. Nigeria accounts for nearly 30 percent of maternal deaths worldwide, and only 59 percent of Nigerian women complete four or more antenatal visits. Why it matters: In Nigerian maternal care the binding constraint is often the device and the data bundle, not the algorithm, and here a network operator is committing both alongside the clinical AI. The 5,000 health workers and 500 facilities are countable before 2030; the partners call the $25 million an anchor for further funding and later expansion, but have not yet published target states or a rollout schedule.
Indiana's Flood-Debris Task Force Uses Drones and AI to Clear 80,000 Cubic Yards With Under Half Its Usual Staff
At a September 23 briefing at the State Emergency Operations Center, Gov. Mike Braun and the Indiana Department of Homeland Security reported that the state-led debris task force has worked in 33 hard-hit communities after this summer's flooding, removing 80,000 cubic yards with an estimated 190,000 still to go. Drones assess sites in place of ground crews, and AI identifies debris types, plans collection routes and optimises removal. Task-force lead Kevin Guthrie said the operation runs with "less than 50% of the employees that would normally be here." FEMA reimburses 75 percent of eligible debris costs in 11 approved counties and the state covers 75 percent of the remaining local share, leaving local governments 6.25 percent. Why it matters: Debris removal is the slowest, most expensive phase of US disaster recovery and is usually contracted to outside teams. Indiana is presenting this model as a template for state-led recovery, with Guthrie calling it "the textbook example of what we take to the next Congress"; the staffing figure is concrete, but officials have put the savings only at "thousands of dollars," and the remaining 190,000 cubic yards are the test.
Gates Closed a $500 Million US Anti-Poverty Program That Unlocked $2.2 Billion in Benefits; Grantees Call the AI Pivot "Total Abandonment"
New reporting by Alex Daniels in The Chronicle of Philanthropy (September 23) puts numbers on what the Gates Foundation gave up. Since 2016 it put roughly $500 million into US anti-poverty research, data and job-quality work that, by its own internal estimates, unlocked $2.2 billion in safety-net benefits, helped 1.4 million Americans access benefits and improved job quality for 100,000 low-wage workers. The foundation shut the effort in October 2025 and redirected toward AI tools meant to help people claim benefits, clear credit problems and find jobs, including its share of a $1 billion, seven-year multi-funder commitment to NextLadder Ventures. UpTogether CEO Jesús Gerena called the pivot "total abandonment." Why it matters: This is the other side of the $1 billion equitable-AI split Impact Signals covered on September 17, with the foundation's own outcome figures for the program it closed. Those figures set a measurable bar for the AI replacement: $2.2 billion in unlocked benefits and 1.4 million people reached. The Ballmer Group and the GitLab, McGovern and Robin Hood foundations are funding similar AI-for-mobility efforts.
