We need to translate Russian news post into English, format per rules.
We need a 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 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.
Let's identify facts:
- Date: 26 August (article presented HydroMEA). So date: August 26.
- HydroMEA chip.
- Human sensory neurons grow in gel with Schwann cells.
- Schwann cells create myelin sheath around axons.
- Microelectrode array measured impulse speed.
- In 2025 work, part of authors of HydroMEA already learned to separate responses of individual human sensory axons using microchannels and electrodes.
- New model added 3D gel similar softness to nerve tissue and Schwann cells.
- In chip center placed neurons, sides Schwann cells.
- Narrow channels held neuron bodies in central compartment and directed axons over electrodes.
- One electrode stimulated axon bundle end, others recorded response arrival.
- Path length divided by delay to get conduction velocity.
- At final point of experiment average conduction velocity was 0.8 m/s in culture with Schwann cells and 0.5 m/s in culture of neurons only.
- Images show myelin sheaths around axons.
- Authors exchanged media between cultures. Difference in speed persisted: authors link it to direct cell interactions and changes around axon, later acceleration — with myelination.
- Authors propose to model demyelination in this system and compare drugs or electrical stimulation by conduction velocity. This will allow correlating visible sheath with axon impulse conduction.
We need to wrap key numbers: date August 26, 0.8 m/s, 0.5 m/s, maybe 2025 (year), maybe HydroMEA name? The name is not a number but a proper noun; maybe we can wrap it? The rule says wrap key numbers, percentages, drug/company/gene names, dates. So company name (HydroMEA) is a chip name; could be considered a company/product name, so we can wrap it. Also Schwann cells maybe not needed. But we need at most 4-5 double asterisks. Let's pick: August 26, HydroMEA, 0.8 m/s, 0.5 m/s, 2025. That's 5.
We need to ensure not wrap whole sentence. So we wrap each individually.
Now citations: There's mention of article presented HydroMEA on August 26 in article; maybe it's a journal? Not given. There's "В работе 2025 года часть авторов HydroMEA уже научилась..." So reference to work 2025 year, but not a journal. There's no explicit journal citation. So we may not need underscores. However we might need to wrap any study/journal citations; none present. So we can skip underscores.
But we might need to wrap something like "article" but not needed.
Make sure to preserve all facts.
Now produce headline: short under 90 chars. Something like: "HydroMEA chip measures myelin‑dependent nerve impulse speed in human sensory neurons". Count characters: Let's count: "HydroMEA chip measures myelin‑dependent nerve impulse speed in human sensory neurons". That's about 78? Let's count: HydroMEA (8) + space=1 =>9, chip (4)=>13, space=14, measures(7)=>21, space=22, myelin‑dependent (maybe hyphen counts as char) let's approximate 16? Actually "myelin‑dependent": m y e l i n ‑ d e p e n d e n t = 16 inc hyphen? Let's count: myelin (6) + hyphen (1) + dependent (9) =16. So total 22+16=38, space=39, nerve(4)=>43, space=44, impulse(7)=>51, space=52, speed(5)=>57, space=58, in(2)=>60, space=61, human(5)=>66, space=67, sensory(8)=>75, space=76, neurons(7)=>83. So 83 chars, okay under 90.
Now blank line, then body paragraphs.
We need short paragraphs 2-3 sentences each.…
