We need to translate Russian news post into natural fluent English, format per rules.
First line: short headline under 90 chars, no markdown.
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 need to preserve all facts, numbers, names, citations exactly.
The Russian text mentions: "19 августа редакционный обзор журнала Nature Biotechnology сопоставил четыре подхода к записи ДНК." So date: August 19 (year not given; assume 2025? Not given; we just keep "August 19". Could be 2024? We'll just keep "August 19". No year given.
Citation: Nature Biotechnology editorial review. We'll wrap that in single underscores: Nature Biotechnology.
Key numbers: "длиной примерно до 200 нуклеотидов" -> about 200 nucleotides. "молекулы длиннее 1 000 оснований" -> longer than 1,000 bases. "ретр... создавали последовательности длиной в десятки пар оснований" -> tens of base pairs. Also "быстрый рост бактерии Vibrio natriegens сокращает этот этап клонирования." maybe not a number.
We need at most 4-5 double asterisk facts. Choose: August 19 date, ~200 nucleotides, >1,000 bases, tens of base pairs (maybe "tens of base pairs"). Could also include Vibrio natriegens? Not a number. Could include "Nature Biotechnology". But that's a citation, goes in single underscores, not double asterisk.
We need to wrap study/journal citations in single underscores. So Nature Biotechnology.
Now produce headline: maybe "Nature Biotechnology highlights DNA synthesis bottleneck". Under 90 chars.
Let's craft: "Nature Biotechnology identifies long accurate DNA synthesis as key bottleneck". Count characters: Let's count: "Nature Biotechnology identifies long accurate DNA synthesis as key bottleneck". Count: N(1)... Let's just ensure <90. It's fine.
Now body paragraphs.
Paragraph 1: Summarize that editorial compared four approaches to DNA writing, explains why creating long accurate sequences slows design-to-test cycle. Include date and citation.
Paragraph 2: Talk about phosphoramidite chemistry standard, makes short oligos up to ~200 nt, errors accumulate, assembly can't fix errors.
Paragraph 3: Describe Sidewinder and MOSAIC assembly methods, their functions.
Paragraph 4: Mention cloning in Vibrio natriegens speeds up step, but bottleneck remains before cloning: need to write and assemble long DNA with acceptable accuracy.
Paragraph 5: Alternative routes: TdT enzyme (Ansa Biotechnologies) yields >1,000 bases; retrons produce tens of bp; four branches address different limits; experimental cycle tempo depends on length, accuracy, speed; for AI-designed proteins, time to experiment includes DNA manufacture and verification; for gene/cell therapy need long accurate sequences for multi-edit constructs; new methods must be compared on varying length/complexity to assess speed, accuracy, reliability.
We need to embed double asterisks for key numbers: August 19, ~200 nucleotides, >1,000 bases, tens of base pairs. Possibly also "Vibrio natriegens" not a number.
We must not wrap whole sentences; just wrap the facts.
Thus:…
