EurekAlert · 28 Oct 2026 · Research

Smoke days at US schools rose from about 7 a year to about 54

EurekAlert carried an Oregon State University release on 28 October 2026. The Environmental Research paper's journal date is 13 October 2026. Across 2006 to 2023, mean annual smoke days rose from 6.8 to 54.4 at public schools and from 9.4 to 112.2 at childcare centers. The abstract covers 115,612 schools and 131,372 childcare centers, and about 2.64 billion student-smoke-days at schools plus 1.02 billion at childcare centers in 2023. Some West Coast buildings had higher indoor fine-particle readings than the air outside on smoke days. The population is students and young children, not a young-adult trial, and sex was not split. This is an exposure study, not a treatment. Not medical advice.

Three Nature papers map immune-cell genetics in nearly 2,000 people

News-Medical reported on 28 October 2026 three Nature papers from the Garvan Institute TenK10K project. The first phase sequenced nearly 2,000 Australians and measured gene activity in more than 5 million immune cells, linking variants to 16 diseases and 44 blood traits. One paper reports more than 180,000 effects on expression. Another links more than 69,000 tandem-repeat variants to expression. A third links more than 240,000 variants to how open the DNA is, and says that layer explained up to 23 percent more disease-linked regions than gene activity alone. One example is a variant that raises OSM in natural killer cells and tracks with higher irritable-bowel risk. Sex and age bands were not given. This is a map, not a personal genetic readout.

Inflammatory joint macrophages were silenced in mice, not in a clinic

News-Medical reported on 28 October 2026 a Science Translational Medicine paper by Rui Peng and colleagues (DOI 10.1126/scitranslmed.adz4081). Single-cell sequencing of mouse synovium and samples from people with osteoarthritis found an expanded group of inflammatory macrophages that carry CD74 and gather where synovium meets cartilage. CD74 partnered with the enzyme ENO2. Lipid nanoparticles carrying silencing RNA against CD74 calmed those cells in a dish and reduced synovial inflammation and disease progression in mice. That intervention is a mouse experiment, not a joint treatment for people. Ages and sex of the human samples were not given in the report. Not medical advice.
