Integrated Dependency and Primary-Patient Profiling Prioritize Nucleotide-Synthesis Vulnerabilities in High-Risk B-ALL

Relapsed B-cell acute lymphoblastic leukemia (B-ALL) remains difficult to treat, yet the space of therapeutic hypotheses is crowded with lineage markers, recurrent fusions, and poorly prioritized dependencies. We asked a narrower question: which noncanonical genes and pathways remain compelling therapeutic liabilities after integrating cell-line dependency data with primary-patient subtype and relapse information? We combined DepMap 24Q2 CRISPR knockout and expression profiles across 32 B-lymphoblastic leukemia/lymphoma models with two public patient cohorts: the DFCI 16-001 pediatric ALL RNA-seq cohort with molecular subtype calls and a paired diagnosis/relapse pediatric B-precursor ALL cohort. Rather than identifying a single dominant target, the analysis converged on a pathway-level program centered on de novo pyrimidine synthesis and connected one-carbon/purine support. UMPS, CAD, DHODH, ATIC, MTHFD1, and FPGS remained the most coherent axis after primary-cohort integration. Pathway-level scoring placed TCF3-PBX1 B-ALL near the top of the combined nucleotide program and highlighted KMT2A-rearranged disease as a strong pyrimidine-focused comparison subtype. Exploratory pharmacology using the public PRISM repurposing screen showed broad activity of the antifolate trimetrexate in annotated B-ALL lines, whereas the public release lacked a clean DHODH inhibitor. These results prioritize nucleotide-synthesis stress, rather than a single receptor or transcription factor, as the most defensible near-term therapeutic hypothesis for high-risk B-ALL and nominate antifolate-versus-pyrimidine-blockade experiments in TCF3-PBX1 and KMT2A-rearranged models as the next concrete step.

The Breakup of AT&T and the Long-Run Quality of American Communications Infrastructure

This paper evaluates a persistent policy claim: that the breakup of AT&T improved competition but weakened the long-run quality of U.S. communications infrastructure. I examine that claim in two steps. First, I situate the argument in the institutional transition from the 1982 Modified Final Judgment and the 1984 divestiture to the competition-oriented regime reinforced by the Telecommunications Act of 1996. Second, I assemble a comparative panel from the World Bank's World Development Indicators for the United States, China, Canada, France, Germany, Japan, South Korea, and the United Kingdom, covering fixed telephony, mobile subscriptions, fixed broadband, and internet use. The evidence rejects a simple decline story. Existing empirical work indicates that Bell's breakup increased the scale and diversity of U.S. telecommunications innovation. Likewise, the United States did not collapse on mobile adoption. The strongest weakness appears instead in the fixed access network. In 2024, the United States trailed the advanced-country peer mean in fixed broadband subscriptions per 100 people, and OECD benchmarks show lower fibre intensity and higher fixed-broadband price baskets than the OECD average. The most defensible conclusion is therefore mixed: the Bell breakup appears to have supported innovation, but the post-Bell regulatory order failed to produce a clearly superior national access network.

Refined Interictal HFO Features Show Pathology-Dependent Utility for Postsurgical Outcome Prediction in an Open Pediatric-Dominant iEEG Cohort

We tested whether refined interictal high-frequency oscillation (HFO) summaries improve prediction of favorable postsurgical seizure outcome in an open pediatric-dominant focal epilepsy cohort. Using OpenNeuro dataset ds005398, we analyzed subject-level metadata for 185 participants and known binary Engel class I outcome labels for 162 participants. We first established a metadata-only baseline using age, sex, recording method, pathology, resection status, and sampling frequency. We then retrieved 183 HFO event tables from the dataset derivatives, aggregated subject-level burden and spatial-distribution features, and evaluated repeated stratified cross-validated logistic regression models. The pooled metadata baseline was weak (ROC AUC 0.564), and naive HFO summaries produced little improvement. Refined HFO features that emphasized event burden, detector-specific rates, and SOZ-resection contrasts modestly improved pooled discrimination (ROC AUC 0.628). The main signal emerged after pathology stratification: in focal cortical dysplasia, refined HFO features improved ROC AUC from 0.435 to 0.541, and in the heterogeneous non-HS/non-tumor “Other” pathology group they improved ROC AUC from 0.455 to 0.582. These gains were moderate rather than decisive, but they support a heterogeneity-centered interpretation: HFO-derived features appear more useful in some pathology groups than in pooled models of mixed focal epilepsy. The result argues against universal biomarker claims and favors pathology-conditional evaluation of interictal HFO methods.

Household Cigarette Exposure and Functional Burden in Pediatric Epilepsy: Pooled Evidence from the 2016-2024 National Survey of Children's Health

Objective: to test whether household cigarette exposure is associated with worse outcomes among U.S. children with current epilepsy. Methods: we pooled the 2016-2024 National Survey of Children's Health topical public-use files and identified 2,371 children with current epilepsy. The primary exposure was household cigarette use; smoking inside the home was analyzed secondarily. Outcomes were parent-reported moderate/severe epilepsy, any emergency room visit, seven or more missed school days, activity limitation, and a composite burden endpoint defined as any ER visit, high absence, or activity limitation. Weighted logistic models adjusted for age, sex, race/ethnicity, poverty, food insecurity, and survey year. Results: household cigarette exposure was common in the epilepsy cohort (weighted 19.2%). It was associated with higher adjusted odds of composite burden (OR 1.85, 95% CI 1.35-2.54), seven or more missed school days (OR 1.38, 95% CI 1.04-1.81), and activity limitation (OR 1.34, 95% CI 1.07-1.68). Associations with parent-rated epilepsy severity and ER use were not clearly different from the null after adjustment. Indoor smoking estimates were less stable because relatively few children were exposed. Conclusions: among children with current epilepsy, household cigarette exposure tracks more strongly with functional burden than with parent-rated seizure severity. The finding is observational and cannot establish causality, but it identifies smoking exposure as a plausible marker of elevated burden in pediatric epilepsy care.

Migratory Butterflies as Pollen Vectors and Neuroecological Models: A Hypothesis-Driven Review Linking Pollination and Neuroscience

Migratory butterflies link plant reproduction and animal navigation in ways that are still understudied across disciplines. This paper argues that butterfly migration should be analyzed as a neuroecological process in which sensory guidance, circadian timing, and directional persistence shape not only animal movement, but also the spatial distribution of transported pollen. We synthesize three bodies of evidence: first, that butterflies can act as effective pollinators in some plant systems even when they are not universally the most efficient pollinator guild; second, that pollen metabarcoding has become a practical way to reconstruct long-distance butterfly movements; and third, that monarch butterflies provide unusually detailed neural and molecular evidence for migration-relevant compass mechanisms, including antennal circadian clocks, central-complex processing of skylight cues, and light-dependent magnetic orientation. Based on this synthesis, we propose a testable framework in which pollination outcomes depend on the interaction among floral contact mechanics, migrant stopover behavior, and the neural control systems that stabilize orientation across changing atmospheric and light environments. Rather than claiming that current evidence already quantifies continent-scale pollen gene flow caused by migratory butterflies, we outline the experiments required to measure it directly. The result is a hypothesis-driven review that positions migratory butterflies as a tractable model for connecting movement neuroscience with landscape-level pollination ecology.
