1. Labor induction jumps at maternal age 40, and at 35 with a failed falsification check, without cesarean or newborn changes

   Turning 35, and again turning 40, moves a pregnancy into the "advanced maternal age" category, which carries more surveillance and more advice to deliver early. Using every US singleton first birth at term from 2016 to 2024, we compared mothers just below and just above each age with a preregistered regression discontinuity, using confidence intervals that stay valid when age is recorded in whole years. Labor induction jumps by 1.19 percentage points at 35 (honest 95% CI 0.7 to 1.68). The preregistered verdict is inconclusive, because the share of first births also jumps at 35, by 0.4 points. At 40, induction jumps by 2.86 points (2.05 to 3.67), and that secondary test meets its confirm rule. Delivery at 39 weeks rises at both ages. Cesarean delivery, NICU admission, low Apgar scores, severe maternal morbidity and term stillbirth show no jump at either age. The label appears to move delivery timing without changing these measured outcomes.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: Among singleton first births at 37-44 weeks in US natality files for 2016-2024, labor induction rises by 1.19 percentage points at maternal age 35 (honest 95% CI 0.70 to 1.68, bias bound 0.1 pp per year squared), but the preregistered decision rule classifies this primary test as inconclusive because the all-parity nulliparity share also jumps at age 35 (0.40 pp, Holm-adjusted p = 0.023).
   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In the same population, labor induction rises by 2.86 percentage points at maternal age 40 (honest 95% CI 2.05 to 3.67), with no covariate discontinuity at 40 after Holm adjustment, so the preregistered secondary test at 40 meets its confirm rule.

2. Species-resolved enzyme profiles leave few eligible longitudinal compensation events in Crohn’s disease

   How many longitudinal observations support a species-resolved microbial compensation analysis in the public inflammatory-bowel-disease multi-omics dataset? A reproducible eligibility audit finds 277 candidate intervals after specimen matching and sequencing-depth filtering. Four broad enzyme annotations yield [6,6,4,0] eligible contributor-decline intervals, in the stated annotation order; only [1,1,0,0] also contain paired numeric calprotectin metadata. These counts describe the specified measurement design, not whether biological compensation succeeds or fails.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: Among 277 consecutive retained Crohn’s specimen intervals under the specified read-filtered, species-relative-abundance-decline and paired-transcript eligibility rules, EC 2.8.3.8, 2.7.2.7, 2.8.3.9 and 2.3.1.19 yield respectively 6, 6, 4 and 0 eligible intervals, of which respectively 1, 1, 0 and 0 also have agreeing numeric calprotectin metadata at both visits.

3. Historical schedules lower assigned grid carbon intensity under deadlines, with higher intensity for some jobs

   Do historical electricity schedules help when jobs arrive throughout the day and cannot wait indefinitely? We evaluated fixed seasonal profiles and recent-history profiles on public Great Britain grid records. For the primary workload, seasonal scheduling lowered mean assigned carbon intensity by 11.24% in 2024 and 12.01% in 2025 relative to immediate execution. Yet 17.61% and 15.55% of jobs received higher intensity. Recent-minus-seasonal mean differences were -0.21 and -0.07 g CO2/kWh. These are retrospective accounting results for a synthetic workload, not measured emissions avoided.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: Conditional on the frozen Great Britain national intensity snapshot and a uniform half-hour arrival workload, three-hour jobs allowed up to six hours of start delay have 11.24% and 12.01% lower mean assigned intensity under 2023-trained seasonal profiles than immediate execution across 17,424 and 17,472 jobs in 2024 and 2025, respectively, while 17.61% and 15.55% have higher intensity and a lagged recent-history profile changes the seasonal mean by -0.21 and -0.07 g CO2/kWh, without establishing causal emissions avoided or future workload performance.

4. Seasonal electricity schedules retain lower average carbon intensity across two later years in Great Britain

   Can a simple electricity-use schedule transfer across years? We selected seasonal three-hour windows using 2023 data and evaluated them in later Great Britain grid records. Relative to midnight use, assigned average carbon intensity was 5.78% lower in 2024 and 13.15% lower in 2025. The schedule performed worse on 137 and 111 days, respectively. A single year-round window did not improve both years. These retrospective accounting results describe the recorded grid; they do not estimate emissions avoided by changing electricity demand.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In the frozen Great Britain national Carbon Intensity API actual series, three-hour seasonal UTC windows selected only from 2023 yield mean assigned-intensity reductions versus 00:00-03:00 UTC of 5.778479% across 364 complete days in 2024 and 13.150070% across 365 days in 2025, compared with -9.430428% and 2.353958% for the single 2023-selected year-round window, while the seasonal rule is worse on 137 and 111 days respectively; these are finite-period accounting comparisons and do not estimate causal emissions reductions.

5. Sparse species-resolved RNA prevents a reliable test of butyrate backup responses in Crohn's

   Can other microbes maintain butyrate-related transcription when a leading contributor declines? A preregistered audit of public IBDMDB profiles finds that the available pathway-level species assignments are too sparse for a reliable answer. Among 375 retained paired Crohn's samples from 52 participants, the primary pathway has positive community RNA in 205 samples but named-species RNA in only 25. The specified longitudinal analysis retains 6 sustained-decline episodes from 5 people. Every retained episode has zero reported RNA from the named alternatives throughout its observation window. These zeros do not distinguish undetected or unassigned transcription from biological failure of compensation.

   • Published, Reproduced, Reviewed.Published, Reproduced, Reviewed: In the audited public IBDMDB HUMAnN3 pathway tables, 375 retained paired Crohn's samples from 52 participants contain named-species PWY-5676 RNA in only 25 of 205 samples with positive community pathway RNA, and the preregistered sustained-contributor-decline analysis yields six episodes from five participants with zero reported alternative-species RNA at all three visits, preventing this operational analysis from distinguishing biological compensation failure from unresolved transcription.
