Cells escaping replicative crisis acquire genome changes after becoming immortal

A preprint, not peer-reviewed, published October 13, 2026, studies human cells as they pass the replicative crisis, a barrier triggered by telomere shortening. Single-cell sequencing found extreme genome instability in crisis cells, while cells that escaped crisis first showed relatively few and simple structural variants. The authors say the genomes of these immortal clones evolve further over later divisions, and propose that crisis selects against cells with aberrant karyotypes.

FLASH X-rays in mice boosted anti-PD-1 therapy against distant tumors, a preprint reports

A preprint, not peer-reviewed, published October 13, 2026, reports a study in mice. Compared with conventional dose-rate X-rays at the same dose, ultrahigh dose-rate FLASH X-rays gave a stronger effect on distant tumors when combined with anti-PD-1 therapy. The authors attribute this to neutrophils keeping their chromatin compact, which reduced neutrophil extracellular trap formation that excluded T cells from primary tumors.

Methylation variability in cancer clusters at PRC2-binding regions, a preprint finds

A preprint, not peer-reviewed, published October 13, 2026, analyzes DNA methylation across hundreds of matched tumor and normal methylomes. It reports that PRC2-associated regions show the highest methylation entropy, and that this pattern emerges early, with precancerous and malignant tissues displaying highly similar profiles.

Regenerating mouse intestine and liver show a brief drop in predicted tissue age

A preprint, not peer-reviewed, published October 13, 2026, reports a study in mice. Using transcriptomic aging clocks, the authors found that regenerating intestinal epithelium was predicted to be younger than controls, and that the change was transient and reversible. They also report decreased transcriptomic age after liver regeneration in old animals.

Engineered cells sense interleukin-23 and could release a neutralizing nanobody

A preprint, not peer-reviewed, published October 14, 2026, describes engineered cell sensors that detect interleukin-23, a biomarker in many autoimmune diseases. The authors report a design that outputs an IL-23 neutralizing nanobody, which they say could reduce inflammation triggered by interleukin-23 secretion.

Vagus nerve stimulation in mice acts through the default mode network, a preprint finds

A preprint, not peer-reviewed, published October 15, 2026, reports brain-wide mapping in mice. The authors found that vagus nerve stimulation activated neuronal ensembles in the default mode network, and that activating or silencing those ensembles reproduced or abolished the stimulation's enhancement of cognitive behaviors. They say the link was mediated by locus coeruleus neuronal subpopulations.

Paid family leave linked to infant brain tracts only where mothers had higher education

A preprint, not peer-reviewed, published October 15, 2026, examines paid family leave and language and white matter measures in 274 infants from the HEALthy Brain and Child Development Study. Neither maternal nor paternal leave was directly associated with language scores, but maternal education moderated the link between maternal leave and fractional anisotropy in two tracts, appearing only among infants whose mothers had relatively high education.

6-Methylnicotine acts more strongly than nicotine on key brain receptors, a preprint says

A preprint, not peer-reviewed, published October 16, 2026, compares (-)6-methylnicotine (6-MN), a nicotine analog added to some vape solutions and nicotine oral pouches, with nicotine. The authors report that 6-MN is a more potent agonist than nicotine at the 4β2 and 3β4 nicotinic receptors and increases these receptors in brain. They note that it is currently unregulated in the U.S. by the Food and Drug Administration (FDA).

Malaria mosquitoes across Ghana show widespread insecticide resistance, a preprint says

The authors report moderate-to-high pyrethroid resistance (4-65%) at all sites, a strong association between the L995F kdr mutation and pyrethroid resistance, and a link between the Ace-1 G280S mutation and pirimiphos-methyl resistance.

LRRK2 inhibition quickly reversed dopamine release deficits in middle-aged mice

A preprint, not peer-reviewed, published October 16, 2026, reports striatal dopamine release in mice with the LRRK2-G2019S knock-in mutation, a model of Parkinson's Disease. The authors found that dopamine release declined with maturity, first in males and then in females, and that 2 hours of LRRK2 inhibition rapidly reversed deficits in middle-aged mice but not in very old ones, which they say bears on the timing of current LRRK2 inhibitor clinical trials.

A switch to posterior-mean evaluation at Amazon reduced test volume and raised signal

A preprint on arXiv, not peer-reviewed, published October 15, 2026, argues that evaluating A/B tests with raw impact estimates rewards sampling noise. Using data on A/B tests at Amazon, the authors report that after a 2024 shift to posterior-mean-based evaluation, test volume declined while precision and the dispersion of true impacts increased, more than doubling signal-to-noise ratios.

Brain MRI AI models plateau because learned features collapse, a preprint reports

A preprint, not peer-reviewed, published October 16, 2026, studies 3D transformer models that classify dementia or mild cognitive impairment against cognitively normal individuals from brain MRI, using Alzheimer's Disease Neuroimaging Initiative data. The authors report that supervised transformers compress almost all of their discriminative signal into one principal component, and that the plateau comes from the learned encoder rather than task difficulty.

Human-wildlife conflict follows shared spatial patterns across regions, a preprint finds

A preprint, not peer-reviewed, published October 13, 2026, compares random forest models of about 11,000 conflict incidents across 29 mammalian scenarios. It reports that conflicts within the same biome tend to share predictors, and that proximity to protected areas was the most consistently important predictor globally. The likelihood of conflict increased with human population density across nearly all scales and contexts.

Coproduced city scenarios reveal varied paths to urban sustainability transformation

A peer-reviewed study in PNAS, published October 16, 2026, analyzes 60 coproduced positive scenario visions and pathways from nine US and Latin American cities, developed with stakeholders in more than 20 workshops. It finds that most pathways combine several theories of change across domains, and that the same strategy, such as car-free regions, can pursue different transformative aims depending on the theory behind it.

Brazilian ranchers on the Dirty List shifted cattle sales to dodge its costs

A peer-reviewed study in PNAS, published October 12, 2026, analyzes millions of cattle transactions in Brazil after ranchers were added to the 'Dirty List', a public registry of employers found to use modern slavery. The authors report that these ranchers cut direct sales to slaughterhouses that had signed sustainable supply chain commitments, and instead laundered cattle through compliant intermediaries or sold to nonsignatory slaughterhouses. They say this weakened the financial cost of listing and likely let beef and leather linked to modern slave labor enter international supply chains.

Grid expansion would cut the cost of net-zero power in Yukon, a preprint finds

A preprint, not peer-reviewed, published October 13, 2026, models how decarbonization could work in the isolated power system of Yukon (Canada). It finds that reaching net-zero without grid expansion would greatly increase system costs, while grid expansion would reduce net-zero costs by about 25%. Intermediate cuts would rely mainly on photovoltaic generation and battery storage, and deeper cuts on large-scale wind with hydrogen storage.
