Washington rule ends federally funded medical aid for some legal immigrants
This is a temporary emergency rule from the Washington Health Care Authority, in effect from October 1, 2026. It applies a federal change so that the definition of qualified noncitizens covers only lawful permanent residents, Cuban/Haitian entrants and compact of free association migrants for federally funded medical assistance. It also lengthens the refugee medical assistance eligibility period from four months to eight months.

Washington proposes medical cannabis product rules to match recent state law
This is a proposed rule from the Washington Department of Health. It would amend chapter 246-70 WAC to align medical cannabis rules with changes to state law from 2SHB 1210 in 2022 and SHB 1453 in 2024, updating terms, label requirements and tax exemptions for medical cannabis products. The department says the changes would help it uphold standards that protect public safety.

Gene conversion drives diversity hotspots in Mycobacterium tuberculosis antigens
A peer-reviewed study in PNAS analyzed complete genome assemblies from 151 clinical isolates of Mycobacterium tuberculosis (Mtb). It finds diversity hotspots driven by gene conversion between homologous genes, with over 300 gene conversion events, mostly in virulence-associated PE, PPE and ESX gene families, including the vaccine candidate PPE18.

Preprint says Denmark's COVID-19 testing and tracing found 55 to 60% of infections
This is a preprint on medRxiv, not yet reviewed by other scientists. It estimates that Denmark's combined national testing and contact tracing program identified on average about 55 to 60% of infected people in the period studied. It says the program as typically implemented was largely ineffective in controlling the pandemic, though a focused approach helped control one large local outbreak.

Preprint identifies possible new readthrough drugs for nonsense mutation diseases
This is a preprint on bioRxiv, not yet reviewed by other scientists. It reports possible new translation readthrough inducing drugs (TRIDs) for premature termination codon (PTC) diseases, including three Sartans, angiotensin II receptor blockers that are FDA-approved for hypertension. In a laboratory test the Sartans were more potent than ataluren, and the authors suggest these compounds might be more effective than ataluren for some of these diseases.

Language model system outperforms generalist physicians in benchmark diagnoses
A peer-reviewed study in Science tests frontier language models on sequential diagnosis, where information and tests are selected step by step. In a controlled benchmark, an artificial intelligence (AI) system reached 83.2% accuracy on New England Journal of Medicine clinicopathological conference cases and 80.3% on MIMIC-IV-ED emergency department admissions, compared with 36.1% and 46.8% for generalist physicians.

Study finds boosting taurine in aged mice dampens inflammation
A peer-reviewed study in Cell reports that taurine levels rise with age in mice and humans. In aged mice, boosting taurine further increased health span and dampened inflammation through its regulation of the NLRP3 inflammasome in macrophages. The findings come from mice.

Study finds education reduces dementia incidence and weakens genetic risk
A peer-reviewed study in PNAS estimates the causal effect of education on Alzheimer's Disease and Related Dementias (ADRD), using a regression discontinuity created by a compulsory schooling reform. It finds education reduces ADRD incidence, and that the reform weakened the relationship between genetics and ADRD incidence.

This is a preprint on bioRxiv, not yet reviewed by other scientists, based on experiments in A549 cells that express ACE2. The authors report that Spike-induced ACE2 clustering activates the PIEZO1 channel, which triggers lysosomal exocytosis, and that the resulting ceramide enhances cell-cell fusion.
