U.S. to reject UN chronic disease pact over ideological dispute

The United States will oppose a United Nations declaration on chronic diseases, Health Secretary Robert F. Kennedy Jr. said, alleging it ignores key issues and advances abortion and “radical gender ideology.” The declaration’s text contains no references to reproductive rights or gender ideology; “gender” appears only in discussion of women’s health. Despite U.S. objections, adoption by the 193 member states is expected in October. Advocates called Kennedy’s stance misleading and at odds with his Make America Healthy Again agenda. They noted the draft had already been softened after industry pushback, removing high taxes and graphic warnings on tobacco, alcohol, and sugary drinks. Critics warned the move would isolate the United States on global health priorities and undermine cooperation on noncommunicable disease and public health goals. (New York Times)

Kennedy’s support erodes as voters back school vaccine rules

A national poll finds 33% of registered voters approve of Robert F. Kennedy Jr.’s performance as health secretary, down from 38% in June. Confidence in medical information from him is low: 17% “very,” 22% “somewhat,” 11% “not so,” and 46% “not at all.” Conducted September 18–21 among 1,276 voters (±3.3 points), the survey also shows 67% support vaccine requirements for public school attendance. Support splits by party: Democrats 91% and independents 70% in favor; Republicans are divided (44% support, 46% oppose). Beyond vaccines, 79% say the country is in a “political crisis.” The results underscore waning trust in Kennedy’s leadership while revealing broad national backing for routine childhood immunization mandates, with disagreement concentrated among Republicans.

Generalist robot brain adapts to damage and unfamiliar bodies

A startup demonstrates a single AI model that can control many robots and keep working under extreme damage—like a quadruped adapting after its legs are cut. The system, an “omni-bodied brain,” is trained across diverse robots and tasks so it can generalize to new hardware and situations, using in-context learning–style adaptation. A smaller research variant, LocoFormer, shows locomotion that transfers from simulated variety to real two- and four-legged machines, including balancing on two wheels or walking on hind legs. The approach is also being tested on robot arms that adjust to changes such as reduced lighting. Rivals are pursuing generalist control, but this effort stands out for breadth; the company raised $300 million in 2024. (Wired)

Fresh microglia transplants emerge as a potential therapy for brain disease

A news article describes research suggesting that replacing the brain’s resident immune cells—microglia—with a fresh supply could help treat a range of conditions, from ultra-rare genetic disorders to Alzheimer’s disease. The piece highlights growing scientific interest in strategies to remove dysfunctional microglia and repopulate the brain with healthier cells, with the goal of restoring homeostasis and clearing damaging debris. It frames the approach as a promising avenue among emerging interventions aimed at neurodegeneration, while noting the early stage of clinical translation. The story was published on September 25, 2025 and includes references to recent papers exploring microglial replacement and related techniques. Further methodological and outcome details likely require access to the full article. (Nature)

Dutch to return Dubois ‘Java Man’ fossil trove to Indonesia

The Netherlands will repatriate more than 28,000 fossils from the Dubois Collection to Indonesia after a government commission concluded they were removed in colonial times “against the will of the people.” The trove includes a skull fragment from Java’s Solo River—historic evidence of Homo erectus often called “Java Man.” The agreement was sealed in Leiden by Dutch education minister Gouke Moes and Indonesia’s counterpart Fadli Zon, with emphasis on preserving scientific access as the collection changes custody. The decision aligns with a broader wave of restitution, with examples of returns by France, Germany, and Belgium. The fossils were excavated in the late 1800s by Dutch anatomist Eugène Dubois when Indonesia was a Dutch colony. (AP)

Ecuadorian court acquits scientists in COVID test procurement case

An Ecuadorian court acquitted molecular biologist Linda Guamán and public health scientist Ximena Abarca of criminal charges tied to Quito’s 2020 purchase of 100,000 allegedly subpar COVID-19 tests, ending a four-year case that drew international attention. On 22 September, the court ruled prosecutors failed to show financial or material harm and acknowledged the researchers’ efforts helped save thousands of lives. Guamán and Abarca, who faced up to 10 years in prison, endured travel bans, ankle monitors, and weekly check-ins for more than two years. They say the ordeal damaged careers and relationships. The defense emphasized that regulators validated the tests and explained LAMP technology’s similarity to PCR. The researchers expect a possible appeal and may seek damages to recover legal costs and reputational harm incurred. (Science)
