An analysis of 497 sampled fish found a strong genetic divide between Northern and Southern Hemisphere groups, with additional structure among Mexican fish and differences between selected captive stocks and wild populations.

MARLOWE ranked microbial contributors well in controlled tests, but its results were less reliable for secondary sources and less specific than MiCId in the broader comparison.

GPS tracking linked reinforcers that joined resident birds with slower dispersal and larger core ranges than birds that stayed in an exclusive reinforcer group. Survival to 55 days did not differ significantly, and the observational design could not show that social integration caused the movement patterns.

A systematic review of GLP-1 and dual GIP/GLP-1 drugs found no consistent signal of psychiatric harm, but said the evidence is too mixed to determine whether most reported outcomes are treatment-related.

Vine tea’s main flavonoid, dihydromyricetin, has shown reported activity against bacteria and fungi in laboratory studies, and some formulations performed better than the free compound. But the evidence is uneven, with no standardized dose, limited direct proof of how the compound works, and safety data that do not answer questions about human use.

In cultured U2OS cells, repeated sodium arsenite exposure was linked to smaller stress granules, reduced assembly at lower follow-up doses and less docking with P-bodies.

A laboratory study links chromosome 16q loss and CYLD depletion to genomic instability, a shift in DNA repair and greater Olaparib sensitivity in cancer models, while tissue and public-data results remain associative.

A laboratory study used temperature-responsive material patterns to turn planar hydrogel constructs into programmed 3D forms, then measured curvature, motion, viability and cell behavior during culture.

Digital FDG PET/CT detected more cases of cranial giant cell arteritis than an initial scan reading and had 100% specificity in the analyzed group, while the study stopped short of showing it should replace ultrasound or biopsy.

TPT1 showed the strongest single-gene separation between sarcopenia and control samples in two bulk muscle-transcriptomic cohorts, while mouse and cell experiments showed matching protein changes. The findings remain exploratory and do not establish causation, disease specificity, or clinical usefulness.

Researchers combined a pangenome, chromatin-accessibility data and simulations to examine how mutational, regulatory and structural differences may contribute to reproductive isolation while populations exchange genes. The analysis found candidate regions in both adjacent comparisons, but no consistent chromatin signal in the two hybrid zones.

A prospective hospital study found that two dried-blood-spot devices closely matched paired serum results for anti-Trypanosoma cruzi antibodies, but low-index positives were sometimes missed.

In young moon jellyfish, treatments that changed the animals’ bacterial community coincided with more frequent arm regeneration. The results point to a possible role for arginine-related metabolism, but model predictions and short-term laboratory tests do not establish how the process works.

A new arXiv preprint reports a reconstruction ensemble that combined multiple cryo-EM ab initio jobs. It achieved 97.4% accuracy on a 45-class asymmetric synthetic benchmark, versus 34.6% for the best single-shot run, and separated four major ribosomal assembly states from junk in an unfiltered experimental stack.

A mathematical analysis of pooled subtree information finds a sharp contrast: three-leaf buckets can hide distinct labelled tree pairs, while n-1 buckets recover pairs across broad size ranges, with small exceptions.

An abstract genotype–phenotype model associated higher penetrance with mutational robustness and lower access to alternative high-fitness regions, while simulations linked infrequent environmental change with penetrance and frequent change with adaptability.

The SWEB model estimated crop water use and root-zone soil moisture across Australian grain regions, with correlations of 0.70 to 0.85 across most regions and higher errors in southeast Australia.

A new arXiv preprint proposes one continuum-mechanics framework for bounded, unbounded and proportionate tissue growth. Its central results are theoretical: the model predicts a stress threshold, long-term proportions set by material parameters and a turnover-dependent growth rate, but it does not test those predictions against biological measurements.

A modeling preprint suggests that near-perfect correlations between species are not a universal sign of ecological instability; the signal depends on whether a slowly relaxing mode is visible above background fluctuations.

A new arXiv preprint develops models in which reproduction and survival favor different trait values and their selection strengths vary across space or time. The analysis predicts shifted optima, asymmetric or potentially two-peaked effective fitness landscapes, and wider or displaced distributions of simulated trait outcomes.

A tissue study of four fatal DENV-4 cases from Ceará’s 2012 dengue epidemic found abnormalities in the liver, lungs and kidneys, while the hearts examined were largely preserved. TNF-α and IFN-γ staining was detected in liver, lung and kidney tissue. The qualitative study cannot estimate risk, prognosis or the frequency of these findings.
