Preprint links brain astrocyte signaling to inflammation in Alzheimer's disease
A preprint, not yet reviewed by other scientists, led by B. Ghosh and colleagues. The study uses mice and cultured cells, and reports that removing soluble epoxide hydrolase (sEH) from astrocytes reduced amyloid pathology and microglial STING activation in mice. The authors report that the molecule 11,12-EET dampened inflammatory signaling in cultured microglia.

Preprint suggests gene-based differences in treatment response may come from trial bias
A preprint, not yet reviewed by other scientists, led by M. J. Tudball and colleagues. Using computer simulations and two population cohorts, the authors show how trial eligibility rules can make treatment benefit appear to depend on polygenic risk scores. They say the apparent effect may reflect bias from eligibility rather than biology.

Proposal would narrow a simplified food benefits application to older or disabled adults
The Washington Department of Social and Health Services (DSHS) proposes amendments to its rule on whether people must be interviewed to get cash and basic food benefits. The changes align with a modification by the United States Department of Agriculture (USDA) Food and Nutrition Administration (FNA) to Washington's elderly simplified application project (ESAP). If adopted, the project would be limited to adults who are disabled or 65 years of age or older, so people aged 60-64 would no longer be eligible.

Preprint reports an oral compound that improved cognitive performance in Alzheimer's mice
A preprint, not yet reviewed by other scientists, led by S. Upadhyay and colleagues. The study combines laboratory work with mice and reports that DELC2, a compound found by screening a large DNA-encoded library, reached the brain when given orally. In 5xFAD mice, the authors report it improved cognitive performance and reduced several amyloid species.

Preprint proposes a proteomic sex index, a continuous measure of sex-related biology
A preprint, not yet reviewed by other scientists, led by E. Viippola and colleagues. Using plasma proteomics data from 51,310 people in six cohorts, it proposes the Proteomic Sex Index (PSI), which measures how far a person's protein profile lies from what is typical for their chromosomal sex. The authors report links to some sex-enriched traits and diseases, and a higher index in Klinefelter syndrome (XXY).

Meta-analysis links higher DNA methylation age to higher mortality risk
A preprint, not yet reviewed by other scientists, led by J. H. Tay and colleagues. It is a systematic review and meta-analysis of 125 articles on DNA methylation age and death risk in adults. The authors report that higher DNA methylation ages were associated with higher risks of all-cause, cardiovascular and cancer mortality, which is an association rather than proof of cause.

Preprint finds a protein called Snail restricts SARS-CoV-2 entry into cells
A preprint, not yet reviewed by other scientists, led by P. P. Sahoo and colleagues. It is a laboratory study in cell cultures, which finds that Snail lowers ACE2 expression and so reduces SARS-CoV-2 entry. The authors also report that infection depletes Snail protein in cell models.

Preprint maps immune responses in 345 people from 13 South American populations
A preprint, not yet reviewed by other scientists, led by C. Choy and colleagues. It reports a single-cell atlas of blood immune cells from 345 people across 13 Indigenous South American populations, at baseline and after stimulation. The authors find that genetic ancestry affects gene expression more than age or sex does.

Preprint says a brain immune pattern exists separately from Alzheimer's disease
A preprint, not yet reviewed by other scientists, led by G. M. Serratto and colleagues. It argues that a strong brain immune pattern, previously seen as an Alzheimer's-specific subtype, also exists in neurologically healthy people and is linked to amyloid pathology. The authors suggest this could allow people to be identified earlier for targeted prevention.

A preprint, not yet reviewed by other scientists, led by N. Swartwood and colleagues. It is a systematic review and meta-analysis of 104 studies of costs faced by households with tuberculosis (TB) in low- and middle-income countries. Estimated per-episode costs of rifampin-susceptible TB ranged from $668 to $9,156 in 2025 International Dollars, with indirect and continuation treatment costs the largest shares.

A preprint, not yet reviewed by other scientists, led by Z. Fang and colleagues. It describes laboratory and mouse studies of new small-molecule inhibitors of CYP8B1, a liver enzyme that controls 12-hydroxylated bile acid synthesis. The lead compound altered bile acid composition, remodeled the gut microbiota and corrected metabolic disease in a mouse model of metabolic dysfunction-associated steatotic liver disease (MASLD).

Proposal would update radiation safety rules for industrial radiation machines in Texas
The executive commissioner of the Texas Health and Human Services Commission, on behalf of the Texas Department of State Health Services (DSHS), proposes amending section 289.228 on radiation safety requirements for industrial radiation machines. The proposal would update and reorganize the rules for non-healing arts radiation generating devices (RGDs), which are used in cargo inspection, law enforcement and security screening. It aims to align the rules with current inspection criteria.

Preprint identifies miR-29 as a control point linking ageing, rejuvenation and cancer
A preprint, not yet reviewed by other scientists, led by I. Craparotta and colleagues. It finds that the molecule miR-29 rises with ageing and falls during two routes to rejuvenation. The authors report that blocking it opposes transcriptional ageing and lowers epigenetic-clock estimates, and that low miR-29 expression marks some tumors with younger epigenetic age.
