Rev-erbα protein appears to limit calcium build-up in artery walls, a preprint finds
This preprint, not yet reviewed by other scientists, combines data from people with diabetes, human artery samples, and experiments in mice and cells. It reports that Rev-erbα is lower in calcified areas of human artery plaques, and that mice without Rev-erb develop faster atherosclerosis and vascular calcification.

Toddlers' early memories seem to persist but become hard to reach, a preprint finds
This preprint, not yet reviewed by other scientists, followed toddlers aged 18 to 24 months through a memory test, with retrieval up to six months later. It reports that memories were not simply erased: many toddlers kept only part of a memory, and the authors say early memories persist in an increasingly inaccessible form.

Temporary rule, in effectWashington Health Care Authority
Washington funds long-term services for a limited group affected by federal law
This temporary emergency rule, in effect from October 1, 2026, sets up a limited community access program with the Department of Social and Health Services (DSHS). It continues state-funded long-term services and supports for people whose immigration status makes them ineligible for federally funded medical assistance, and the agency will use standard rule-making to make the changes permanent.

Washington rules change children's initial health screen from must to may
This is a final rule, effective November 7, 2026. The Health Care Authority removes outdated language to align with federal requirements and with the department of children, youth, and family's policies, and it provides that children entering out-of-home placement may, instead of must, receive an initial health screen within five days.

Mice carrying a human IL6RA variant show less artery disease and aneurysm
This is a preprint, not yet reviewed by other scientists, and it is a study in male mice. Researchers introduced the human IL6RA variant into mice, report that it changes soluble IL6RA levels as in humans, and say it significantly prevents atherosclerosis and abdominal aortic aneurysm (AAA).

Adding linafexor to low-dose semaglutide gave more weight loss in a trial
This preprint, not yet reviewed by other scientists, reports a randomized, placebo-controlled phase 2 trial in 62 adults with obesity, type 2 diabetes and metabolic dysfunction-associated steatohepatitis (MASH). Taken by mouth with semaglutide for 16 weeks, linafexor led to 6.17% weight loss versus 2.91% with placebo, with gastrointestinal side effects similar in both groups (23.3% vs. 18.8%).

Higher development linked to stronger government responses to PEPFAR funding freeze
This preprint, not yet reviewed by other scientists, examines how governments in Sub-Saharan Africa responded to disruption of President's Emergency Plan for AIDS Relief (PEPFAR) funding after the suspension of United States foreign aid. It finds that higher Human Development Index (HDI) scores were significantly associated with stronger government responses, while links for gross domestic product (GDP) per capita and HIV prevalence were not significant after adjustment for multiple comparisons.

Women's empowerment linked to completing India's PM-JAY verification, preprint finds
This preprint, not yet reviewed by other scientists, is a cross-sectional observational study of 14,378 women in six Indian states who were eligible for the Pradhan Mantri Jan Arogya Yojana (PM-JAY) publicly funded health insurance scheme. It shows a link, not a cause: high women's empowerment was associated with higher odds of completing PM-JAY verification, but not with outpatient service use.

Chemotherapy leaves a narrow set of surviving cell states in breast tumours
This preprint, not yet reviewed by other scientists, combines spatial, single-cell, protein and other data from breast cancer. It reports that chemotherapy depleted the pretreatment cell states and repeatedly favored a restricted set of survivors, and that the capacity to reach those survivor states was partly present before treatment.

Shape of lipid nanoparticles may affect how well mRNA works in lab cells
This preprint, not yet reviewed by other scientists, is a laboratory study of lipid nanoparticles (LNP), the carriers used to deliver messenger RNA (mRNA). It reports that adding more DSPC lipid changed particle shape from spherical to non-spherical, and that non-spherical particles gave higher and more sustained protein expression, a difference the authors say uptake alone does not explain.

Diet and exercise through young adulthood tied to better midlife heart health
This preprint, not yet reviewed by other scientists, is an observational study of participants in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort, which shows a link, not a cause. It finds that people who kept higher diet quality and higher physical activity through young adulthood had much higher odds of high midlife cardiovascular health, and the combined association was larger than either factor alone.

Adult pneumonia in the United States carries $30.80 billion a year in direct costs
This preprint, not yet reviewed by other scientists, estimates annual direct healthcare costs of community acquired pneumonia (CAP) among adults in the United States, using 2023 Medical Expenditure Panel Survey data. Most of the cost is hospital care, and the authors also link higher pneumococcal vaccination uptake to lower pneumonia mortality across states.

Wikipedia drug-safety warnings may be weaker in Russian, Arabic and Hebrew
This preprint, not yet reviewed by other scientists, audits drug-safety warnings for 33 drugs in English, Russian, Arabic and Hebrew Wikipedia, using large language models as a measuring tool. It estimates that warnings were weaker in the Russian, Arabic and Hebrew editions than in English, but the uncertainty ranges include no difference, and the model codes are not yet checked against human coding.

Castration extends male mouse lifespan at three ages, preprint reports
This preprint, not yet reviewed by other scientists, is a mouse study in which male UM-HET3 mice, a genetically heterogeneous stock, were castrated at 20, 60 or 240 days of age. Castration at each age prevented early excess male mortality and increased median lifespan, and the authors say the responsible testicular factors act rapidly and their continued presence is needed to sustain higher male mortality.

Pairing decision-only medical AI with a language model reduced framing effects
This preprint, not yet reviewed by other scientists, tests two decision-only AI models, Jev and OpenAI Decisions, alone and paired with the language model GPT-6 Luna, using clinical case presentations. The authors report that pairing reduced decision changes caused by added labels or pressure cues, that triage accuracy stayed near 81% to 82%, and they describe the work as a proof of concept.

Adherence patterns may explain conflicting primaquine results in malaria campaigns
This preprint, not yet reviewed by other scientists, uses a data-driven agent-based model of malaria infection and transmission to examine primaquine, a drug that targets mature gametocytes, the stage that passes malaria from humans to mosquitoes. The authors report that differences in how people adhere to multi-round mass drug administration (MDA) campaigns could explain conflicting earlier results, and they predict that primaquine in routine case management could significantly reduce the prevalence of infection.
