We need to translate Russian news post into natural English, format per rules.
First line: short headline under 90 chars. No markdown, no '#'.
Then blank line, then body split into short paragraphs (2-3 sentences each), separated by blank lines.
Wrap few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks . At most 4-5 per post, never a whole sentence.
Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).
We have a preprint on bioRxiv dated August 24. That's a date. Also numbers: 1,531 healthy human samples, 14 tissue/cell groups, ~90% variance explained, 163 CpG sites, CpG islands entropy 23% lower, blood and colon >90% variance explained around islands, brain islands contribution up to 99%, flanking region ~1000 bp DNA calendar age explains 47-68% local dispersion. Also mention SCARLET model linking age-related DNA methylation marks in blood with hematopoietic stem cell division mode.
We need to select at most 4-5 key facts to bold. Choose: 1,531 samples, 14 tissue groups, ~90% variance explained, 163 CpG sites, 23% lower entropy in CpG islands, >90% variance explained in blood/colon, brain islands up to 99%, calendar age 47-68% in flanking region. That's many; need limit to 4-5. Choose most important: 1,531 samples, ~90% variance explained, 163 CpG sites, CpG islands entropy 23% lower, brain islands contribution up to 99% (or blood/colon >90%). Let's pick: 1,531 samples, ~90% variance explained, 163 CpG sites, CpG islands entropy 23% lower, brain islands contribution up to 99%. That's 5.
Now citations: The preprint on bioRxiv August 24. Also mention SCARLET model (maybe a study). We need to wrap study/journal citations and publication references in single underscores. So we can put bioRxiv, August 24 and maybe SCARLET model? SCARLET is a model name, not a publication. Could treat as SCARLET? Probably better to put the preprint reference: bioRxiv, August 24. Also maybe mention that it's a preprint (not peer-reviewed). Could also include bioRxiv as citation.
We need to preserve all facts, numbers, names, citations exactly. Do not add commentary.
Now produce headline: something like "Stem cell division history explains most epigenetic noise across tissues". Under 90 chars.
Let's count: "Stem cell division history explains most epigenetic noise across tissues" length: let's count characters including spaces. "Stem"(4) + space1=5, "cell"(4)=9, space=10, "division"(8)=18, space=19, "history"(7)=26, space=27, "explains"(8)=35, space=36, "most"(4)=40, space=41, "epigenetic"(10)=51, space=52, "noise"(5)=57, space=58, "across"(6)=64, space=65, "tissues"(7)=72. So 72 chars, okay.
Now blank line.
Then body paragraphs.
We need short paragraphs 2-3 sentences each.
Let's craft maybe 4 paragraphs.
Paragraph 1: Introduce study: On August 24, a preprint on bioRxiv presented analysis of 1,531 healthy human samples from 14 tissue/cell types. Authors accounted for cell-type proportions and found that estimated stem‑cell division history explained about 90% of the epigenetic noise captured by their statistical model.
We need bold numbers: 1,531, 90%. Also date maybe bold? But we limited bold to 5 items; we already used 1,531 and 90% (two). We'll also bold 163 CpG sites, 23% lower entropy, brain islands up to 99% (that's five). So we should not bold date. Good.
Paragraph 2: Describe epigenetic noise measure: They used Shannon entropy of DNA methylation at individual CpG sites; higher entropy indicates a more mixed methylated/unmethylated state. To isolate division effects, they estimated and subtracted cell‑type composition before correlating age with division history.…
