Sleep & dementia risk: A new review argues sleep’s “housekeeping” helps clear brain waste, linking disrupted sleep rhythms to higher dementia risk and pointing to heart-rate variability as a possible non-invasive risk signal. Diabetes testing nuance: An ADA-focused case-based webinar highlights when HbA1c can mislead due to abnormal hemoglobin or altered red blood cell lifespans, and how separation methods can flag limitations. China space science: Shenzhou-22 returned ~41 kg of space-station samples from 23 experiments, including life-science specimens like artificial embryos and brain organoids, plus advanced materials for gravity-related studies. Citizen biodiversity push: Scotland’s temperate rainforest survey logged 1,100+ species in West Cowal using volunteers plus AI-assisted ID, building a needed baseline for conservation. Quantum materials breakthrough: Brown and Michigan researchers stabilized a theorized intermediate “missing step” in metal crystal transformations, with unusual optical behavior that could feed quantum tech. Tech in classrooms: Armenia signed on to bring ChatGPT Edu to 50,000 students, teachers, and researchers via a phased rollout. Wildlife discovery: Himalayan pit viper research splits one “species” into five lineages, including new species. Photon weirdness: A study explores quantum light behavior where photons can effectively exit a medium sooner than expected under specific conditions. AI governance: The UK plans AI facial age checks to support asylum age assessments when documentation is disputed. Core Scientific permits: Georgia opened/closed comment windows on air permits for Core Scientific backup diesel generators at two data-center sites.
